Environmental law in India is usually described as a single body of law, and the description misleads from the first sentence. There is no environmental code. There is no single statute that a reader can open to find the law of pollution, forests, wildlife and biodiversity set out in one ordered scheme. What exists is a collection of statutes passed half a century apart, each resting on a different constitutional foundation, each applying to a different map of the country at the moment of its birth, and each administered in practice by institutions that were designed for one of them and then borrowed by all the others. A reader who does not know which foundation a statute stands on will misunderstand where it applies, who enforces it, what happens when a state disagrees with it, and even whether breaking it is a crime.

The organising fact of the whole field can be stated in one sentence: the route determined the reach. Water and wildlife were subjects the Constitution gave to the states, so when Parliament first legislated on them it could do so only for states whose legislatures asked it to, and the resulting statutes spread across the country state by state, by consent and adoption. Air pollution and the general environment reached the statute book by a different door: Parliament used its power to legislate for implementing an international agreement, and a law made through that door applies to the whole territory of India from the day it commences, with no state consent required and none sought. Between those two doors sits a constitutional amendment that moved forests and wildlife onto shared ground, and underneath all of them sits a single set of pollution control boards, created under the Water Act, deemed to exist under the Air Act, and used in practice to run much of the umbrella statute as well. The field is not a system designed at one moment. It is a sediment of constitutional opportunities, laid down in the order in which the opportunities appeared.

That sediment has practical consequences that a purely thematic account misses. Because the earliest statutes rest on state consent, their amendment still runs through a consent mechanism, and a Parliament that wishes to soften or strengthen the Water Act in the present decade must either secure fresh state resolutions or accept that the amendment will not run everywhere at once. Because the later statutes rest on a treaty power, their content is whatever the Central Government’s rules say it is, and the operative text of Indian environmental law for most industries is not an Act at all but a notification. Because the boards are one set of bodies wearing several statutory hats, a factory’s dealings with the state are dealings with a single office administering several laws of different ages and different constitutional pedigrees. This article sets out that architecture statute by statute and route by route, states the strongest version of the two standard arguments about the framework, and gives a verdict on each.

What environmental law in India consists of

Stripped to its components, the field has five layers. The first is constitutional: a directive principle instructing the state to protect and improve the environment, a fundamental duty laid on every citizen in the same direction, and a judicial reading of the right to life that converted those aspirations into an enforceable right to a wholesome environment. The second layer is the statutes themselves: the Wild Life (Protection) Act of 1972, the Water (Prevention and Control of Pollution) Act of 1974, the Forest (Conservation) Act of 1980, the Air (Prevention and Control of Pollution) Act of 1981, the Environment (Protection) Act of 1986, the Public Liability Insurance Act of 1991, the National Green Tribunal Act of 2010 and the Biological Diversity Act of 2002, together with the much older Indian Forest Act of 1927 that still governs the classification of forest land on the ground. The third layer is the delegated legislation made under the umbrella Act of 1986: the rules and notifications on environmental impact assessment, coastal regulation, hazardous waste, biomedical waste, plastic waste, electronic waste, noise, hazardous chemicals and genetically engineered organisms, which between them contain most of the obligations an operator actually has to obey. The fourth layer is institutional: the Central Pollution Control Board, the State Pollution Control Boards, the National Biodiversity Authority and its state counterparts, the forest bureaucracy, and the ministries that direct them. The fifth layer is adjudicatory: the Supreme Court and the High Courts exercising writ jurisdiction, and since 2010 a specialised tribunal hearing most environmental disputes under the principal statutes.

Is there a single environmental code in India?

No. India has never enacted a consolidated environmental code, and the field remains a set of separate statutes passed decades apart under different constitutional powers, supplemented by a large body of rules and notifications made under the Environment (Protection) Act of 1986 and by case law built on the right to life in Article 21 of the Constitution.

The field even lacks a shared vocabulary at the level of the statute book. The word environment itself is defined only in the umbrella Act, where Section 2(a) provides that it includes water, air and land and the inter-relationship which exists among and between them and human beings, other living creatures, plants, micro-organisms and property. The older statutes define their own media instead: the Water Act defines pollution of a stream or well, the Air Act defines an air pollutant and an emission, the wildlife statute defines animal, habitat and hunting, and the diversity statute defines biological resources. Each statute therefore carries a private dictionary, and a word of art in one Act, from industry to occupier to trade effluent, cannot be assumed to bear the same meaning in the next. Practitioners read the definitions section of the governing Act before anything else, a habit the architecture imposes.

The absence of a code is not an oversight awaiting correction. It is the direct product of the way the field was built. Each statute arrived when a constitutional route for it became available: a pair of state-consent statutes in the nineteen seventies, a treaty-based pair in the nineteen eighties, a tribunal statute and a biodiversity statute in the following decades. Consolidation has been proposed more than once, most elaborately by the high level committee chaired by T. S. R. Subramanian in 2014, and has never been carried through, for reasons that go to the foundations: a Parliament that repeals a consent-based statute and replaces it with its own text faces the same consent problem at the point of repeal that it faced at the point of enactment. The sections that follow take the layers in the order in which they were laid down, because the order is the explanation.

The constitutional map before any statute

The Constitution of 1950 contains no entry for the environment as such, and no article uses the word. Legislative power over the subjects that environmental law would later occupy was distributed by the Seventh Schedule in a pattern that made a national environmental statute almost impossible to write. Water, meaning water supplies, irrigation, canals, drainage, embankments, water storage and water power, was placed in Entry 17 of the State List, subject only to Entry 56 of the Union List, which covers the regulation and development of inter-state rivers and river valleys to the extent Parliament declares control by the Union to be expedient in the public interest. Public health and sanitation sat in Entry 6 of the State List. Forests sat in Entry 19 of the State List. The protection of wild animals and birds sat in Entry 20 of the State List. Land, the subject under which most disputes about natural resources would eventually be fought, sat in Entry 18 of the State List. A Parliament that wished to legislate against water pollution in 1970 faced the plain difficulty that the Constitution had given the subject to the state legislatures, and had given it no general power over the environment because the environment had not been imagined as a legislative subject at all.

Two provisions of the Constitution supplied the way around that difficulty, and the whole shape of the field follows from the difference between them. The first is Article 252. Where the legislatures of two or more states pass resolutions to the effect that a matter in the State List should be regulated by Parliament by law, Parliament may legislate on that matter for those states, and any other state may afterwards adopt the resulting Act by passing a resolution of its own. An Act made this way is not a national Act in the ordinary sense. It is a statute whose territorial extent is assembled state by state, and clause 2 of the same article keeps the arrangement honest: such an Act may be amended or repealed only by an Act of Parliament passed in like manner, which is to say through the same consent procedure, and it cannot be amended or repealed by a state legislature even for that state’s own territory. The land cluster earlier in this series met the same mechanism at the point of repeal, where a repeal statute built on Article 252 could not take effect across the country without state participation, a point worked through in the account of the urban land ceiling repeal. Article 252 is an instrument of negotiated federalism: the Centre drafts and administers, but only inside a perimeter the states have drawn.

The second provision is Article 253, and it works in the opposite way. Notwithstanding the normal distribution of legislative power, Parliament may make any law for the whole or any part of the territory of India for implementing any treaty, agreement or convention with another country, or any decision made at an international conference, association or other body. A law under Article 253 needs no state resolution, consults no state legislature, and applies everywhere the law says it applies from the moment of commencement. Its only precondition is external: there must be an international commitment to implement. Where Article 252 produces a statute whose map is drawn by consent, Article 253 produces a statute whose map is drawn by the treaty. The two provisions between them explain why some Indian environmental statutes are uniform national law and others began life as partial law covering a named list of states, and they explain it without any reference to the importance Parliament attached to the subject. The door that was open decided the size of the room.

A third feature of the original design matters for what followed. The Constitution’s directive principles and fundamental duties contained nothing about nature in 1950, and the right to life in Article 21 was framed in the language of personal liberty. Environmental protection entered the constitutional text only in 1976, and it entered the enforceable part of the Constitution only through judicial interpretation a decade and a half after that. The statutes therefore came first, the constitutional text second and the rights jurisprudence third, which is the reverse of the sequence most accounts assume.

Two other doors existed in theory and were not used, and their non-use confirms the analysis. Entry 56 of the Union List let Parliament take control of inter-state rivers where it declared Union control expedient in the public interest, and a determined Centre might have built a law of pollution for inter-state river basins on it. What Entry 56 could never support was a general law of water pollution, since most polluting discharges reach streams, wells and municipal systems that no one could call inter-state rivers, and Parliament in fact used Entry 56 sparingly even for river development itself. Entry 52 of the Union List, covering industries whose control Parliament declares expedient in the public interest, supported the industrial licensing code of the nineteen fifties and might have carried rules for industrial effluents alone. It could not reach municipal sewage, agricultural run-off, hospitals, hotels or any of the non-industrial sources a pollution law must govern, and a statute built on it would have been an industrial regulation measure with environmental effects rather than an environmental law. Article 249, which lets the Rajya Sabha resolve by a two-thirds majority that Parliament should legislate on a State List matter in the national interest, was the third theoretical route, and the most fragile: a law made under it lasts only while the resolution endures, renewable a year at a time, which is no foundation for a permanent regulatory system with boards, standards and consents meant to run for decades. The doors that were used were used because they were the only ones that opened onto the whole subject and stayed open.

The inheritance the statutes displaced

The framework of the nineteen seventies did not descend on an empty field, and the older law explains several of the framework’s gaps. The Indian Forest Act of 1927, a colonial consolidation, classified government forests into reserved forests, protected forests and village forests, armed forest officers with powers over felling, grazing, transit of forest produce and the settlement of rights, and remains the working statute of forest administration: the Forest (Conservation) Act of 1980 does not replace it but sits on top of it as a central check on diversion, so that forest law in India is a two-storey structure in which the ground floor is a century old. Environmental grievances below the statutory level were handled by the general law. Municipal legislation imposed duties of sanitation and abatement of nuisance on local bodies, the Indian Penal Code made public nuisance an offence, and the civil law of tort supplied actions in nuisance and negligence and the strict liability rule for dangerous escapes associated with Rylands v Fletcher. These instruments shared a common shape: they were reactive, local and case-by-case, with no standards set in advance, no specialised regulator, and no power in any authority to license an activity in advance on environmental conditions. The boards-and-consents design of 1974 was a deliberate rejection of that shape. It also explains why the older instruments were never repealed and never integrated: they continue underneath the framework, and a grievance that fits no modern statute can still be framed, as the Ratlam litigation framed it, in the language of municipal duty and public nuisance.

Stockholm and the consent route: wildlife and water come first

The trigger for the entire framework was external. In June 1972 the United Nations Conference on the Human Environment met at Stockholm, the first global conference to treat the environment as a subject of international law, and India attended with a delegation led by Prime Minister Indira Gandhi, who addressed the plenary and argued that poverty itself was a polluting condition which environmental policy could not ignore. The Stockholm Declaration that emerged called on states to enact environmental legislation and to build institutions for it. India returned from the conference with a commitment and a constitutional problem: the subjects on which legislation was most urgently wanted, water and wildlife, sat in the State List. The solution adopted for both was Article 252. State legislatures passed resolutions surrendering the subject to Parliament for their territories, Parliament legislated, and the two founding statutes of Indian environmental law entered into force as partial statutes whose extent clauses are, in effect, lists of the states that had said yes.

The first fruit was the Wild Life (Protection) Act, 1972, Act 53 of 1972, which received assent on 9 September 1972. Its preamble records that the legislatures of eleven states, namely Andhra Pradesh, Bihar, Gujarat, Haryana, Himachal Pradesh, Madhya Pradesh, Manipur, Punjab, Rajasthan, Uttar Pradesh and West Bengal, had passed resolutions under Article 252 asking Parliament to legislate on the protection of wild animals and birds, a State List subject under the original Entry 20. The Act created the machinery of protected areas, sanctuaries and national parks, prohibited hunting of scheduled animals, and regulated trade in trophies and animal articles. Its territorial biography illustrates the consent route precisely. States beyond the original eleven brought it into force by adoption, Jammu and Kashmir, which had its own political settlement with the Union, enacted a separate wildlife statute in 1978 and stood outside the central Act for decades, and the Act’s reach at any given moment was a question that could only be answered state by state.

The second and more consequential fruit was the Water (Prevention and Control of Pollution) Act, 1974, Act 6 of 1974, the statute whose institutional skeleton the entire field still uses and whose own detailed anatomy belongs to its statute pillar. Its preamble recites resolutions from twelve states, namely Assam, Bihar, Gujarat, Haryana, Himachal Pradesh, Jammu and Kashmir, Karnataka, Kerala, Madhya Pradesh, Rajasthan, Tripura and West Bengal, and it applied from the start as well to the Union territories, whose legislatures the Centre did not need to consult. Section 1 of the Act provided for the rest of the country in the manner Article 252 requires: any other state could adopt the Act by resolution, and the Act gives the adopting state a commencement of its own on the date of adoption. The Act’s stated purpose was to prevent and control water pollution and to maintain or restore the wholesomeness of water, and its operative idea was institutional rather than prohibitory. It created a Central Board and State Boards, gave them power to lay down standards for sewage and trade effluents, and required consent from the State Board before an industry could be established or an outlet for discharge used. Offences under the Act were criminal, punishable with imprisonment, and prosecution could be launched only by or with the sanction of a board, a design choice whose consequences run through the enforcement debate examined later in this article.

Two features of this first phase deserve emphasis because later accounts flatten them. The first is the order of legislating. India legislated on water before air and on wildlife before either, not because a plan said so but because those were the subjects for which state consent could be assembled in 1972 and 1974, while a general law on air or on the environment had to wait for a route that did not need consent. Sequence here is evidence about constitutional opportunity, not about priorities. The second feature is the board design. The Central Pollution Control Board was constituted in September 1974 under Section 3 of the Water Act, and State Boards followed under Section 4 in the states where the Act ran. These bodies were the first statutory environmental regulators in the country, and because they existed when later statutes arrived, later statutes used them. The field’s institutional unity, such as it is, is an accident of this ordering: the boards came with the first pollution statute and were never redesigned for the larger field they came to administer.

The administrative state grew alongside the statutes, and its growth followed the same incremental pattern. A Department of Environment was created in the Government of India in 1980, between the Water Act and the Air Act, and in 1985 it became a full Ministry of Environment and Forests, the institutional home from which the umbrella Act would be run the following year. Before 1980, environmental subjects were scattered across ministries of agriculture, health, industry and works, and pollution control was largely the business of the boards the Water Act had created; after 1985 there was a single ministry to sponsor legislation, issue the rules and notifications under it, and answer for the field in Parliament. The sequence matters to the reading of the statutes. The boards were not created as the field arm of a ministry designed for the purpose. They were created first, under a consent statute, and the ministry arrived a decade later to inherit them.

The two consent statutes then lived the biographies their foundations prescribed. The wildlife statute, once its subject moved to the Concurrent List, could be amended by Parliament for the whole country without fresh resolutions, and it was, repeatedly: a series of amendments tightened the trade provisions, the amendment of 1991 created a Central Zoo Authority and completed the prohibition on hunting save in narrow exceptions, the amendment of 2002 added conservation reserves and community reserves to the protected area family, and the amendment of 2006 inserted a National Tiger Conservation Authority with a statutory tiger conservation plan regime. Each of those amendments ran nationally, because the competence ground had shifted under the statute in 1977; the Act that began as a patchwork of eleven states’ consent became, by constitutional renovation, a genuinely national conservation code in everything but its birth certificate. The Water Act enjoyed no such renovation. Its subject stayed in the State List, its amendments of 1978 and 1988, the latter substantially strengthening penalties and inserting the Board’s direction power, were carried through the consent procedure and ran where the Act ran, and half a century on, its amendment still begins, as the 2024 amendment began, with resolutions in state legislative assemblies. The contrast between the two founding statutes is the cleanest available proof that foundations are not formalities: one amendment in 1976 to the Seventh Schedule silently rewrote the future amendability of a statute passed in 1972, and left its sibling of 1974 permanently dependent on the procedure of its birth.

The Forty-second Amendment rewires the map

The Constitutional (Forty-second Amendment) Act of 1976, passed during the Emergency, redrew the Seventh Schedule in the middle of the framework’s construction. Acting on the recommendations associated with the Swaran Singh Committee, it transferred two subjects out of the State List into the Concurrent List: forests, which became Entry 17A, and the protection of wild animals and birds, which became Entry 17B. On subjects in the Concurrent List both Parliament and the state legislatures may legislate, with the central law prevailing in case of repugnancy under Article 254, subject to the assent procedure in that article. The same amendment inserted the two environmental provisions of the constitutional text itself: Article 48A in the directive principles, providing that the state shall endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country, and clause (g) in Article 51A, making it a fundamental duty of every citizen to protect and improve the natural environment including forests, lakes, rivers and wild life, and to have compassion for living creatures. The insertions and the reasoning behind them are set out in the series account of the Forty-second Amendment itself. The environmental provisions of the amendment commenced on 3 January 1977.

The significance of the rewiring is easy to overstate and easy to miss. It did not nationalise environmental law. Water, the subject of the first pollution statute, stayed exactly where it was, in Entry 17 of the State List, and it sits there still; Parliament has never acquired ordinary legislative power over water pollution, which is why the Water Act remains a consent statute to this day and why its amendment in 2024 had to be built on fresh resolutions rather than on the Concurrent List. What the amendment changed was the ground under forests and wildlife. From 1977, Parliament could legislate on those subjects for the whole country without asking any state, and when a genuine central forest statute arrived in 1980 it used that power. The amendment also changed the terms of argument. Article 48A is a directive principle, non-justiciable by the express command of Article 37, and Article 51A duties are not enforceable by courts either; neither provision gives a citizen a claim. Their function proved to be interpretive and legitimating: they gave the courts a constitutional text to read alongside Article 21, and they gave governments a stated mandate when later statutes were challenged as intrusions into state subjects. The two consent statutes of 1972 and 1974 were left standing on their original foundations, unrepealed and unrefounded, so the field after 1977 contained statutes resting on three different kinds of ground: consent, concurrency and, shortly, treaty.

The two inserted provisions also had a judicial career that their non-justiciable form did not predict. Courts cited Article 48A and clause (g) of Article 51A as interpretive companions to Article 21 across the environmental case law of the following decades: the directive supplied the state’s side of the duty and the fundamental duty supplied the citizen’s, and benches deployed the pair to justify everything from the closure of polluting tanneries to the protection of a lake against encroachment, on the reasoning that a constitution which obliges the state to protect the environment and the citizen to cherish it cannot intend the right to life to exclude the conditions of a livable environment. The Supreme Court said as much structurally when it read the two provisions together with Article 21 in the Vellore judgment discussed below. What the amendment did not do is equally definite. It created no fundamental right to the environment, which had to wait for Subhash Kumar’s reading of Article 21; it did not disturb the distribution for water, land or public health; and it did not retrospectively alter the foundations of the two statutes already enacted, whose consent basis state governments continued to respect when those statutes were amended. A constitutional amendment that is constantly described as the moment India constitutionalised environmental protection in fact changed the competence map for two subjects, supplied two unenforceable texts of great persuasive power, and left the rest to judges and to the treaty power.

The treaty route: air and the umbrella statute

The Air (Prevention and Control of Pollution) Act, 1981, Act 14 of 1981, took the other door. Its preamble does not recite resolutions of state legislatures. It recites that decisions were taken at the Stockholm conference to take appropriate steps for the preservation of the natural resources of the earth, including the preservation of the quality of air and the control of air pollution, and that it was considered necessary to implement those decisions. That is the language of Article 253, and its consequence is written into the Act’s extent: the Air Act extends to the whole of India. It was assented to in March 1981 and commenced on 16 May 1981 everywhere at once. No state was asked, no state could be left out, and no state acquired a version of the Act with a commencement date of its own. The contrast with its elder sibling is the cleanest demonstration in the field that the constitutional route, not the subject matter, decided the shape of the statute: water pollution law had to be assembled, air pollution law could simply be declared. The Air Act’s detailed provisions, including its declaration of air pollution control areas by state governments, are treated in its own statute pillar.

The Act also performed the field’s neatest institutional economy, in Sections 3 and 4. It created no new boards. Section 3 provides that the Central Pollution Control Board constituted under the Water Act shall exercise the powers and functions of the Central Board under the Air Act, and Section 4 provides that a State Pollution Control Board constituted under the Water Act is deemed to be the State Board under the Air Act. One set of officials, appointed under a 1974 consent statute, thereby acquired jurisdiction over a 1981 treaty statute of national extent. In states that had adopted the Water Act the arrangement was seamless. The deeming device is the formal root of the single-window reality of Indian pollution control: one office, one consent culture, several statutes.

Five years later the treaty route produced the framework’s capstone. On the night of 2 and 3 December 1984, methyl isocyanate escaped from the Union Carbide plant at Bhopal and killed thousands of people in the worst industrial disaster in Indian history. The catastrophe exposed a gap that the two medium-specific statutes could not fill: there was no general law under which the Central Government could set standards for hazardous processes, restrict where dangerous industries could be sited, or direct the closure of a dangerous operation across the board. The Environment (Protection) Act, 1986, Act 29 of 1986, was Parliament’s answer, assented to on 23 May 1986 and brought into force on 19 November 1986. The disaster that prompted it has its own legislative aftermath, owned elsewhere in this series; the connective point here is the route. The Act’s preamble again invokes the Stockholm decisions of 1972, the Act legislates under Article 253, and it extends to the whole of India. Its detailed scheme is treated in the umbrella statute’s own pillar; what matters for the architecture is its design. The Act is short, twenty-six sections in four chapters, and deliberately skeletal. Section 3 arms the Central Government with power to take all measures it deems necessary or expedient for protecting and improving the quality of the environment and preventing, controlling and abating environmental pollution, including laying down standards for the quality of air, water and soil and maximum allowable limits for environmental pollutants. Section 5 empowers the Central Government to issue directions to any person, officer or authority, including directions for closure, prohibition or regulation of an industry, operation or process. Sections 6 and 25 confer the rule-making power through which the skeleton acquired its flesh. The offences provision, Section 15, originally punished contravention with imprisonment of up to five years or fine or both, placing the umbrella in the criminal column of the field’s ledger until the decriminalisation wave redrew that column.

The design deserves a closer look because it became the template for everything after. Section 3, clause 2, illustrates the breadth of the central power with a list that runs from laying down standards for environmental quality in different media, through restricting the areas in which industries and processes may be carried on, to prescribing procedures and safeguards for handling hazardous substances and for the prevention of accidents. Clause 3 of the same section empowers the Centre to constitute authorities to exercise its functions, a provision through which bodies as consequential as the Central Ground Water Authority and the loss-of-ecology authorities of particular litigation were later built without further legislation. Section 23 permits delegation of the Centre’s powers to state governments and their officers, which is the statutory bridge by which the umbrella Act’s centralised text is administered through the state machinery the older statutes built. The Act thus contains, inside twenty-six sections, a complete kit for governing a field by executive instrument: standard-setting, siting control, direction, delegation and authority-creation. The later history of the field, in which subject after subject was regulated under the umbrella rather than by fresh primary legislation, is the history of that kit being used.

The Bhopal catastrophe contributed one further statute to the map. The Public Liability Insurance Act of 1991 imposed on owners handling hazardous substances a duty to take out insurance policies against which immediate relief could be paid to victims of an accident, a no-fault compensation mechanism of narrow but real scope. It belongs in any complete map of the field because it is among the seven statutes listed in the Schedule to the National Green Tribunal Act, and so shares the forum that the principal statutes share.

Two features of the treaty route repay attention before the rules are examined. The first is its elasticity. The Environment (Protection) Act of 1986 rests, on its own preamble, on decisions taken at Stockholm in 1972, fourteen years before its enactment and in response to a domestic catastrophe that Stockholm had nothing to do with. Article 253 asks only that a law be for implementing an international decision; it does not require proximity in time, a specific treaty text, or a showing that each provision answers an international obligation, and the courts have not read such limits into it. Stockholm thus became a standing constitutional warrant under which Parliament could legislate on the environment generally, in perpetuity, without returning to the states. The second feature is a wrinkle inside the Air Act that shows how even a national-extent statute is operated federally. The Act’s consent regime applies in air pollution control areas, and those areas are declared by state governments under Section 19; a state therefore controls the geography in which the central statute’s central prohibition bites, and the early map of Indian air pollution control was drawn in state capitals under a statute no state had consented to. Extent and operation are different things, and the field’s federal character lives in the operation as much as in the extent.

The two treaty statutes divided even a single pollutant between them in a way that shows the improvisation of the period. Noise was written into the Air Act by an amendment of 1987, which brought noise within the definition of an air pollutant when present in excessive concentration, yet the operative regime of ambient noise standards, silence zones around hospitals and schools, and restrictions on horns, loudspeakers and construction hours came to rest in the Noise Pollution Rules of 2000 under the umbrella Act, administered in the districts by magistrates and police as much as by the boards. A subject can thus be defined in one statute, standardised under a second, and enforced by officers of a third system, and only a connective account of the kind attempted here will tell a sufferer from noise which instrument to open first.

The operative law lives in the rules

A reader who stops at the Acts will have read the smallest part of Indian environmental law. The Environment (Protection) Act was designed as an enabling shell, and the substantive obligations that govern an industrial operator, a hospital, a builder, a municipal body or a ship-breaker are located overwhelmingly in the rules and notifications issued under it, which the Central Government can make, amend and withdraw without returning to Parliament. The point is structural, not incidental. The rules power in Section 6 reaches the standards for emissions and effluents, the procedures for environmental clearance, the siting of industries, the handling of every significant waste stream, and the conditions on which hazardous activities may proceed at all.

What is the difference between a rule and a notification in environmental law?

Rules are delegated legislation made under an Act’s rule-making power, drafted as a code for a subject such as hazardous waste and laid before Parliament. A notification is the Gazette instrument by which government publishes a decision, and under the umbrella Act notifications carry weight: the impact assessment and coastal regulation zone regimes both rest on notifications, not rules.

The inventory makes the point concrete. The environmental impact assessment regime, under which specified projects require a prior environmental clearance from the Centre or from a state-level authority before construction begins, began with a notification in January 1994 and was comprehensively replaced by the notification of 14 September 2006, which divided projects into categories, prescribed screening, scoping, public consultation and appraisal, and created the standing expert committees whose recommendations decide applications. The coastal regulation zone notification of 1991 classified the coastline into zones and restricted construction within them, and was replaced by a fresh notification in 2011 and again in 2019, each reissue redrawing the setback lines and the list of permissible activities for the entire coastline without a parliamentary vote. The waste streams each carry their own rules: hazardous waste rules first made in 1989 and since recast, biomedical waste rules first made in 1998, plastic waste management rules, electronic waste rules, solid waste management rules, construction and demolition waste rules. The Noise Pollution (Regulation and Control) Rules of 2000 prescribe ambient noise standards and silence zones. The rules of 1989 for the manufacture, use, import, export and storage of hazardous micro-organisms and genetically engineered organisms created the approval committees through which biotechnology is environmentally regulated. The Manufacture, Storage and Import of Hazardous Chemicals Rules of 1989 govern inventories, safety audits and on-site emergency plans for chemical installations, a direct Bhopal inheritance. None of these instruments appears in the text of any Act. Each of them can be, and regularly is, amended by the executive acting alone, subject to the laying requirement and to judicial review on ordinary administrative law grounds.

Two consequences follow for anyone trying to understand the field as a whole. The first is about scrutiny. A change to the operative law of pollution in India usually takes the form of a draft notification, a short consultation window and a Gazette publication, rather than a bill, a debate and a division. The second is about stability. Standards that live in subordinate legislation can be relaxed or tightened at the speed of executive decision, which is why the argument about the strength of Indian environmental law, taken up in full below, cannot be settled by reading the Acts: the Acts are mostly permissive shells, and the severity of the regime at any moment is an executive setting rather than a legislative settlement.

Oversight of a legislature that mostly does not legislate

The formal check on this delegated empire is the laying requirement. Section 26 of the umbrella Act requires every rule made under it to be laid before each House of Parliament, which may modify or annul it, and the parliamentary committee on subordinate legislation exists to examine instruments of this class. In the environmental field the check operates weakly, for reasons of volume and technique rather than of constitutional design. The instruments that matter arrive as notifications, which are not all subject to the same laying discipline as rules; they are long, technical and numerous; and the sanction of annulment is a blunderbuss no House will fire at a standards schedule on which thousands of consents depend. Judicial review fills part of the space: a notification can be struck down as exceeding the parent Act, as arbitrary, or for breach of the procedure the parent instrument itself prescribes, and clearance jurisprudence is rich in projects remitted for fresh appraisal because the process in the notification was not followed. But review polices legality, not wisdom, and a standard lawfully relaxed stays relaxed. The honest description of accountability for the operative environmental law of India is therefore a thin parliamentary layer, a real but legality-bound judicial layer, and a thick layer of professional and public scrutiny of draft notifications, which has become, by default, the field’s substitute legislature. Consultation on drafts, once perfunctory, is the arena in which industry associations and environmental organisations contest the content of the law itself, and the outcomes of those contests, exemptions granted or withheld, thresholds raised or held, are the legislative history of the operative field.

The clearance regime as the rules universe in miniature

The impact assessment notification deserves separate treatment in a connective account, because it is the largest regulatory structure in the field that exists without any statutory parent other than three sections of the umbrella Act. Under the notification of 2006, projects in listed categories, from mining leases and river valley projects to industrial estates, building construction and townships above threshold sizes, require a prior environmental clearance. Category A projects are appraised at the Centre by a sector-specific Expert Appraisal Committee advising the ministry; Category B projects are appraised at state level by a State Expert Appraisal Committee advising a State Environment Impact Assessment Authority. The procedure prescribes screening, scoping through terms of reference, preparation of an environmental impact assessment report, a public consultation conducted in the district where the project sits, and appraisal leading to grant or refusal with conditions. Conditions typically require compliance reporting by the proponent, monitoring by the regional offices of the ministry, and adherence to the management plan on which the appraisal proceeded. The public consultation stage is the field’s one formally participatory institution: residents affected by a project may appear and object, and the proceedings are recorded and must be addressed in the final assessment, which makes the district hearing the point at which the resident of the earlier examples enters the legal process by right rather than by tolerance.

The connective significance of the regime is threefold. It demonstrates the reach of the umbrella design: a clearance system governing the largest investments in the economy rests on a notification issued under Sections 3 and 6 of an Act whose text nowhere mentions impact assessment, clearance or appraisal committees. It demonstrates the corresponding vulnerability: because the regime is a notification, its categories, thresholds, exemptions and procedures can be and repeatedly have been recast by the executive, and litigation over amendments to the notification, over standard terms of reference and over post-facto clearances for projects begun without clearance, is a standing feature of the tribunal’s docket. And it demonstrates the field’s institutional opportunism, since the appraisal committees that decide are not statutory bodies with tenure and procedure fixed by law but expert committees constituted by the government under the notification, serviced by the ministry whose projects they appraise in other capacities. A single instrument thus exhibits the delegation depth, the executive mutability and the institutional improvisation that this article identifies everywhere in the architecture.

Standards: the numbers that run the field

Between the Acts and the regulated activity stand the standards, and their legal geography explains more practical behaviour than any offence provision. Indian environmental law knows two families of numbers. Ambient standards state the quality the receiving environment must maintain: the National Ambient Air Quality Standards, revised comprehensively in a notification of 2009, prescribe limits for twelve pollutants in the air people breathe, differentiated for industrial, residential and ecologically sensitive areas, and the Central Pollution Control Board’s designated-best-use classification sorts surface waters into five classes, from water fit for drinking without conventional treatment after disinfection, through bathing and treated drinking water, down to water fit only for irrigation, industrial cooling and controlled waste disposal. Source standards state what a discharger may release: general standards for the discharge of environmental pollutants into water, land and air are collected in the schedules to the Environment (Protection) Rules, and industry-specific standards for dozens of named industries, prescribing effluent and emission limits process by process, stand alongside them. A board consent then translates the applicable numbers into the conditions of a particular plant, and a State Board may impose conditions stricter than the national floor where local conditions require it.

Three features of this standards architecture matter for the whole-field view. The first is depth of delegation: a standard that decides whether a factory is lawful sits three levels below Parliament, in a schedule to a rule made under an Act, and can be altered by substituting a table in a notification, which happens regularly and attracts a fraction of the attention an amending bill would draw. The second is asymmetry: ambient standards are aspirations the state sets for itself and are largely unenforceable by a citizen against the government of a polluted city, while source standards are obligations enforceable against the discharger, so the field’s numbers bind the regulated far more tightly than they bind the regulator. The third is variation: because consent conditions are set state by state and board by board within a national floor, two identical plants on opposite banks of a state boundary can lawfully discharge on different numerical terms, which is the standards-level expression of the federal structure the founding routes created. A reader who wants to know what Indian environmental law requires of any real activity should read the standards and the consent, not the Act: the Act supplies the authority, the schedule supplies the law.

The standards also have a judicial life that their drafters did not script. In litigation the prescribed numbers are treated as floors of legality rather than as guarantees of safety: a discharge within its consent limits can still ground proceedings where the receiving environment is demonstrably degraded, because the precautionary principle, as the Supreme Court installed it in the law of the land, places the burden on the actor to show that an activity is environmentally benign, and a schedule of numbers issued by the executive does not exhaust what the constitutional right requires. Conversely, a breach of a numerical standard is the cleanest possible foundation for a direction, which is why tribunal litigation so often reduces to a contest over sampling: whose sample, taken where, analysed by which laboratory, against which schedule. The standards system thereby performs a function beyond regulation. It converts the open-textured right to a wholesome environment into measurable propositions that boards can administer and tribunals can decide, and the conversion is imperfect in both directions, since what cannot be measured tends to drop out of the legal account of a place, and what can be measured tends to stand for the whole of it.

The conservation statutes run on different machinery

Not every environmental statute is a pollution statute, and the conservation side of the field administers itself through entirely different institutions. The Forest (Conservation) Act, 1980, Act 69 of 1980, began as an ordinance promulgated on 25 October 1980 and rests on the competence Parliament acquired when forests moved to the Concurrent List: the Centre legislates on a shared subject, so the Act extends to the whole of India and no consent or treaty was needed. Its operative provision, Section 2, is a gate rather than a code. It forbids any state government or authority from directing that a reserved forest cease to be reserved, that forest land be used for a non-forest purpose, that forest land be assigned by lease to a private party, or that naturally grown trees be cleared for reafforestation, except with the prior approval of the Central Government. A single prior-approval requirement over diversions converted the Centre into the effective decision-maker for mining leases, dams, roads and plantations touching forest land across the country, and created the clearance process around which the forest side of the field is organised. The Act was renamed in 2023 as the Van (Sanrakshan Evam Samvardhan) Adhiniyam, a change whose substance belongs to the forest cluster of this series; for the map it is enough to note that the conservation statute of 1980 is administered not by the pollution boards at all but by the environment ministry and the state forest departments, advised by a Forest Advisory Committee.

The wildlife side is administered by yet another chain. Under the Wild Life (Protection) Act of 1972, authority runs through the Director of Wildlife Preservation at the Centre, Chief Wildlife Wardens in the states, and the protected area network of sanctuaries and national parks that the Act’s later amendments elaborated into tiger reserves and conservation reserves. Its offences remained criminal after the decriminalisation wave, with substantial terms of imprisonment for offences involving scheduled species, which places wildlife law in a different enforcement world from pollution law: forest guards and wildlife officers, not board inspectors, and prosecution rather than adjudicated penalties. Amendments passed in 2022 recast its schedules to track the Convention on International Trade in Endangered Species, a further reminder that treaty commitments keep feeding the field through several doors at once.

The Biological Diversity Act, 2002, Act 18 of 2003, assented to on 5 February 2003, is the field’s second treaty statute of the later period, enacted to give effect to the Convention on Biological Diversity signed at Rio de Janeiro in June 1992. Its premise is regulatory in a different register: biological resources are sovereign assets, access to them by foreign persons and companies requires approval, and the benefits of commercial use must be shared with the communities that conserved the resource. It built a three-tier structure of its own, a National Biodiversity Authority established in 2003 and headquartered at Chennai, State Biodiversity Boards for the states, and Biodiversity Management Committees in local bodies, charged among other things with preparing People’s Biodiversity Registers. The Act extends to the whole of India, and its presence in the Schedule to the tribunal statute means that access and benefit-sharing disputes take the same forum path as pollution appeals. For the connective map, the diversity statute completes the demonstration: by 2003 Parliament had built environmental institutions under every available route, and each route left its institution in the shape the route required, a national authority for a treaty statute, state boards for a consent statute, a ministerial gate for a Concurrent List statute.

One set of boards, many masters

The pollution side of the field is administered by bodies that predate most of the statutes they serve. The Central Pollution Control Board, constituted in September 1974 under Section 3 of the Water Act, advises the Central Government on pollution matters, coordinates the State Boards, lays down standards in consultation with them, collects and publishes technical data, and runs nationwide monitoring programmes. The State Pollution Control Boards, constituted under Section 4 of the Water Act in the states where that Act runs, carry the field-level functions: inspecting premises and effluent treatment plants, sampling discharges and emissions, and granting or refusing the consents without which an industry may not be established or operated. Through the deeming provisions described earlier, the same two tiers became the boards under the Air Act without a single new appointment. Under the umbrella Act the Centre retained the formal powers, but in practice the boards furnish the sampling, analysis and inspection infrastructure through which much of the rules universe is policed, and the Centre has repeatedly authorised board officials to exercise functions under the 1986 Act. The Water (Prevention and Control of Pollution) Cess Act of 1977 added a levy on water consumption by scheduled industries and local authorities, designed to fund the boards; the cess was abolished in the taxation changes of 2017, leaving the boards funded through budgets and consent fees, a financial detail with institutional consequences examined in this article’s companion statute pillars.

Who appoints the chairperson and members of a State Pollution Control Board?

The state government does. A State Board under Section 4 of the Water Act consists of a chairperson nominated by the state government, officials of the state government, representatives of local authorities, nominees of state government companies and corporations, and non-official members representing agriculture, fishery, industry, trade and other interests, with a full-time member-secretary appointed by the state government.

That composition explains a large part of the field’s enforcement character. The boards are statutory bodies, but they are staffed through state nomination, financed substantially through state channels, and directed at officials who serve alongside the development departments whose projects they must police. Their technical staffing has been a chronic subject of criticism in the literature of the field: sanctioned posts unfilled, laboratories understaffed, inspection ratios thin against the number of regulated units. The strongest version of the weak-enforcement account of Indian environmental law rests here, and it is a genuinely strong account. A consent regime of real sophistication on paper is operated by institutions that in many states lack the chemists, engineers and lawyers to run it at the tempo the statutes assume, and prosecution under the original scheme required board sanction, which placed the decision to enforce inside the institution whose capacity was already the constraint. The decriminalisation wave, whatever else it did, can be read as an official admission that the criminal enforcement machinery the boards were given in 1974 had not been worked as designed.

The boards nonetheless matter beyond their capacity problems, because they are the one institution every pollution question reaches sooner or later. A resident complaining of a discharge, a factory applying to expand, a court seeking a factual report on a polluted stretch of river, a tribunal deciding an appeal against a closure direction: each of these paths runs through the board of the state concerned. The connective consequence of the 1974 design is that the quality of Indian environmental enforcement is, in most states, the quality of a single institution wearing the hats of the Water Act, the Air Act and the umbrella rules at once.

The boards’ standard-setting and classification work deserves a paragraph of its own, because it is where the boards most resemble a legislature. The Central Board co-ordinates the State Boards and, in the scheme of both founding statutes, industry-specific and general standards for effluents and emissions are developed through the central board system and adopted into the rules under the umbrella Act, so the numerical limits a factory must meet typically originate in board committee work and acquire legal force through a notification the ministry issues. The boards also classify industry by pollution potential. A categorisation developed by the Central Board and applied by the State Boards sorts industries into red, orange, green and white categories by a pollution index, and the category governs the period for which consent is granted, the fees payable, and in the case of white-category industries, whether consent is required at all in many states. That last consequence connects the boards’ administrative practice directly to the 2024 amendment’s exemption power: exempting whole categories from consent had been happening through classification policy before it was written into the Water Act as a central power. The boards further run the national monitoring programmes through which air and water quality are measured across the country, which gives them a second, quieter function: they generate the data on which the state of the environment is officially known, and gaps in the monitoring network are gaps in what the legal system can see.

The direction power between the two board tiers

One structural feature of the board system generates recurring friction and deserves isolation. Each founding statute contains a directions section, Section 18 in both the Water Act and the Air Act, under which the Central Board is bound by the written directions of the Central Government, a State Board is bound by the written directions of the Central Board and of its state government, and a conflict between a Central Board direction and a state government direction is referred to the Central Government for decision. The State Board is thus the servant of two masters whose instructions can conflict, with the conflict resolved upward to the Centre. In practice the Central Board uses the power to direct State Boards on matters from categorisation of industries to the closure of grossly polluting units in critically polluted areas, and the state nomination of the Board’s members operates alongside this central direction power as the counterweight. The arrangement is the federal compromise of 1974 expressed as an administrative law rule, and the 2024 amendment’s provision for the Centre to prescribe the manner of nominating state chairpersons shifts its balance: the master that appoints would join the master that directs, in the same hands. Much of the federal objection in the parliamentary debate on that amendment, including the objection that water monitoring belongs at state and local level, was aimed at precisely this junction.

Consent: the operating core where the statutes meet

If the field has an operating core, it is the consent system, because consent is the point at which every pollution statute’s abstractions become a document a factory must hold. The design repeats across the founding pair. Under Sections 25 and 26 of the Water Act, no person may establish or take steps to establish an industry, operation or process, or bring into use a new or altered outlet for sewage or trade effluent, or begin a new discharge, without the previous consent of the State Board. Under Section 21 of the Air Act, no person may establish or operate an industrial plant in an air pollution control area without the Board’s previous consent. The two consents are administered as one practice: applications are made together, inspections are joint, and the Board issues consent to establish before construction and consent to operate before commissioning, for terms calibrated to the pollution category of the industry. Conditions attached to a consent import the rest of the field into the document: effluent and emission standards from the umbrella rules, conditions of the environmental clearance where one exists, water consumption limits, sampling and reporting duties. Breach of a condition is breach of the statute under which the consent was granted, which is why the consent, a board-issued instrument, is the single most litigated document in Indian environmental law.

Consent also displays the field’s layered appellate geography in miniature. Refusals and conditions were originally appealable to appellate authorities constituted under the Water and Air Acts themselves, and specified board orders are among the matters the tribunal statute later made appealable to the National Green Tribunal, so a dissatisfied applicant can travel from a state committee room to a national tribunal on a question that began as the siting of a settling tank. The consent stage is further where the boards acquired their sharpest teeth short of prosecution: amendments in 1988 to the Water Act and in 1987 to the Air Act inserted direction powers, Section 33A and Section 31A respectively, empowering a Board to issue written directions including closure of an industry and disconnection of its electricity and water, the same species of power Section 5 of the umbrella Act gives the Centre. Much of what the umbrella Act is credited with was thus replicated inside the older statutes within two years of its enactment, a convergence that underlines the connective truth of the field: the instruments migrate between statutes, and the institutions stay the same.

Five statutes, five routes, five reaches

The table below compresses the argument of this article into a single object. Each row is a principal statute. The columns record the constitutional provision the statute rests on, whether it applied to the whole country at once or spread state by state, the body that administers it, whether its offences stand in the criminal or the civil column after the decriminalisation wave, and the forum in which a challenge to action under it is heard. Read across any row and the route explains the rest of the row.

Statute	Constitutional route	Reach at enactment	Administered by	Offences	Forum for challenge
Wild Life (Protection) Act, 1972	Article 252, on resolutions of eleven states	Consenting states first, others by adoption	Chief Wildlife Wardens and the state wildlife administration	Criminal, with imprisonment retained	Ordinary courts and the High Courts; the Act stands outside the tribunal’s Schedule
Water (Prevention and Control of Pollution) Act, 1974	Article 252, on resolutions of twelve states, with the Union territories included from the start	Twelve states and the Union territories first, other states by adoption	Central Pollution Control Board and State Pollution Control Boards	Criminal under the original Act; civil penalties in states that have adopted the 2024 amendment	National Green Tribunal, the Act being first in the tribunal’s Schedule
Air (Prevention and Control of Pollution) Act, 1981	Article 253, implementing the Stockholm decisions	The whole of India at once	The same boards, deemed to be the boards under this Act	Civil penalties through adjudicating officers since 1 April 2024, with the consent offence in Section 21 retaining imprisonment	National Green Tribunal
Forest (Conservation) Act, 1980	Concurrent List Entry 17A, inserted by the Forty-second Amendment	The whole of India at once	Central Government approval through the environment ministry, with the state forest departments	Criminal, with a short term of imprisonment under the Act	National Green Tribunal
Environment (Protection) Act, 1986	Article 253, implementing the Stockholm decisions	The whole of India at once	Central Government and authorities it constitutes, with the boards supplying the field machinery in practice	Civil penalties through adjudicating officers since 1 April 2024	National Green Tribunal

The table also records what it cannot show. Two of the five rows rest on Article 252 and two on Article 253, yet no two rows are alike in consequence: the wildlife statute kept its criminal offences and stands outside the tribunal, while the water statute lost its criminal offences only in adopting states and sits first in the tribunal’s Schedule; the two treaty statutes share a route and a commencement pattern but differ entirely in design, one a classical consent-and-prosecution statute and the other an enabling shell filled by rules. Route is the first determinant of a statute’s biography, not the only one, and the biography is what a practitioner or a resident actually has to deal with.

How the layers stack on a single project

The architecture is easiest to see whole when it is applied to one facility. Take an integrated cement plant of middling size, sited near a limestone deposit. Before construction, the project needs an environmental clearance under the 2006 impact assessment notification, because cement manufacture is a listed category: the proposal is screened, terms of reference are set, an impact assessment is prepared, a public hearing is conducted in the district, and an expert appraisal committee recommends grant or refusal to the ministry or to the state-level authority, depending on the category into which the plant’s capacity places it. If any part of the mining lease or plant site is forest land, the separate gate of the Forest (Conservation) Act opens, and diversion requires the prior approval of the Central Government on the advice of its Forest Advisory Committee, with compensatory afforestation and a net present value payment as the standard conditions of approval. If the site falls within the regulated band of the coast, the coastal notification adds a third clearance geography; if it falls within the eco-sensitive periphery of a sanctuary or national park, wildlife approvals through the standing committee of the National Board for Wildlife add a fourth. None of these processes is conducted by the pollution boards, and none is found in the text of a single statute that the proponent can read.

The boards enter at the construction and operation stages. Before establishing the plant, the proponent needs consent to establish from the State Board under the Water Act and the Air Act, which examine the effluent and emission arrangements, the water source and the stack design; in practice, for a project requiring environmental clearance, the consent to establish follows the clearance, since the board will treat the clearance conditions as the baseline of its own. Before commissioning, the proponent needs consent to operate, granted for a term fixed by the industry’s pollution category and renewable on inspection and compliance. Alongside the consents run the umbrella Act’s authorisations: an authorisation to handle hazardous waste under the hazardous waste rules, registration or authorisation for any plastic or electronic waste streams the plant generates, and the continuing conditions of the clearance itself, breach of which the ministry can pursue under the umbrella Act’s direction power in Section 5. If the plant handles hazardous substances above the threshold quantities in its process, the Public Liability Insurance Act requires an insurance policy to stand behind accident claims. A grievance about the plant can then arise in at least four legal shapes: a complaint to the Board seeking inspection and directions; an appeal against a consent or a clearance to the National Green Tribunal; a writ petition in the High Court framing the pollution as an Article 21 violation; or a prosecution or penalty proceeding under whichever statute the facts fit. The plant experiences this as one regulatory weather system. The law experiences it as five statutes, three constitutional routes, two tiers of boards and one tribunal, and the difference between those two experiences is the subject of this article.

The same architecture viewed from the receiving end explains the resident’s experience of the field. Consider a cluster of small dyeing units discharging coloured effluent into a stream behind a residential colony. The residents’ grievance is single; their legal options are plural, and each runs to a different door. A complaint to the State Board invites inspection and sampling, and the Board may act on its consent conditions, issue directions under the Water Act including closure and disconnection of utilities, or prosecute with its own sanction. A complaint under the umbrella Act can be carried to the Central or state government, and a citizen may set the criminal machinery of that Act in motion only after giving sixty days’ notice of the intention to complain, a filter built into Section 19 of the Act. An application to the National Green Tribunal can seek closure, compensation and restitution of the stream, since the Water Act stands in the tribunal’s Schedule. A writ petition can frame the discharge as a violation of the residents’ Article 21 right and ask the High Court to supervise the Board itself. Which door the residents choose determines the remedy they can get, the speed at which they can get it, and the authority arrayed against the units, and nothing in the situation tells them which door is right: that knowledge is professional knowledge about the architecture, which is the strongest practical argument for understanding the field as this article presents it, as a structure of routes and institutions rather than as a single environmental law.

A linear project shows the same stacking in its most politically charged form. A highway widening that passes through a forest division and the periphery of a protected area requires environmental clearance under the impact assessment notification for the road category, forest diversion approval under the 1980 Act for every stretch of forest land, wildlife clearance where the alignment touches a protected area or its eco-sensitive zone, board consents for its hot-mix plants, crushers and batching plants along the route, and coastal clearance for any segment in the regulated coastal band, with tree-felling permissions and compensatory afforestation obligations computed stretch by stretch. The proponent is typically a national highway authority of the same Union whose ministries appraise the clearances, a concurrence of roles the appraisal system manages rather than resolves. It was this class of project, roads, railways, transmission lines, power and mining, for which the Subramanian committee proposed its fast track in 2014, and the political economy of linear projects, nationally sponsored, locally resisted, judicially supervised, is the standing background against which every proposal to simplify the clearance system is actually a proposal to redistribute the vetoes the architecture distributes among committees, boards, courts and affected residents.

Enforcement in practice: boards, courts and the space between

Between the paper scheme and outcomes on the ground stands a working relationship between the boards and the courts that neither set of statutes describes. In the public interest litigation that dominates the field, the Supreme Court and the High Courts rarely find environmental facts themselves. They commission them, and the commissioner is typically the Central Board, a State Board, or a committee built around them: the boards sample, analyse, map the sources and report, and the bench then directs on the basis of the regulator’s own data. The arrangement converts the boards into the evidentiary arm of the courts, and it cuts both ways. It gives judicial orders a technical foundation they would otherwise lack, and it exposes the boards to judicially recorded findings about their own inaction, since the reports frequently document violations the board had power to address unaided. A second bridging practice is compensation. In the Bichhri litigation, Indian Council for Enviro-Legal Action v Union of India in 1996, the Supreme Court applied the polluter pays principle to make chemical industries finance the remediation of land and water they had contaminated, and compensation thereafter became a standard judicial and tribunal remedy, with the Central Board in time developing methodologies for computing environmental compensation by reference to the pollution load, the duration of violation and the scale of the operation, which the tribunal applies across categories of default from illegal groundwater extraction to non-compliant waste handling. A third bridge is the bank guarantee and the closure drive, instruments by which courts and boards condition continued operation on secured compliance.

The significance of this middle layer for the article’s argument is that it is customary rather than statutory. The framework as enacted knew nothing of court-commissioned board reports, compensation methodologies or continuing judicial supervision; all of it grew from the interaction of a rights-bearing constitution, an expanded law of standing and regulators whose own enforcement tempo the courts found wanting. When the tribunal was created in 2010 it absorbed much of this customary layer into a designed institution, which is why the tribunal’s practice, expert members, compensation orders and all, feels like the codification of the preceding litigation culture rather than a new departure. A reader who understands only the statutes will miss the layer in which a large part of Indian environmental law is actually transacted.

The courts complete the structure

The third layer of the field was built by judges, and it was built on a text that says nothing about the environment. Article 21 provides that no person shall be deprived of his life or personal liberty except according to procedure established by law. Beginning in the late nineteen seventies the Supreme Court read “life” expansively, and the environment entered enforceable constitutional law through that door. In Municipal Council, Ratlam v Shri Vardhichand, decided in 1980, the Court upheld the prosecution of a municipality that had failed in its statutory duty to provide sanitation, treating a public nuisance of open drains and stench as a legal wrong the state could be compelled to remedy and speaking of social justice as requiring the authorities to act. The standing revolution that made mass environmental litigation possible arrived with the public interest litigation of the following decade: in the Rural Litigation and Entitlement Kendra litigation from 1985, concerning limestone quarrying in the Doon valley, the Court entertained a letter-based petition by an organisation with no property at stake, appointed expert committees, and ordered quarries closed, establishing both the procedural pattern and the supervisory style of Indian environmental adjudication. The doctrinal keystone followed in Subhash Kumar v State of Bihar in 1991, where the Court held that the right to life under Article 21 includes the right of enjoyment of pollution-free water and air for the full enjoyment of life, and that a petition under Article 32 lies where that enjoyment is threatened. From that holding the modern structure descends: environmental harm is a fundamental rights violation, enforceable directly in the Supreme Court and the High Courts, at the instance of any public-spirited person.

The M. C. Mehta litigation, a sequence of cases run from the middle nineteen eighties onward by a single advocate-petitioner, carried the structure into industrial regulation itself: oleum leakage, the Taj Mahal trapezium, vehicular emissions in Delhi, tannery effluents into the Ganga. The specific doctrines forged in those cases, including the rule of absolute liability for hazardous industries, are owned by the doctrine cluster of this series; at the level of the whole field the Mehta cases matter because they demonstrated that the courtroom, not the boardroom of a pollution control board, was the venue in which Indian environmental standards would be made effective against large polluters. In Vellore Citizens Welfare Forum v Union of India in 1996 the Court completed the doctrinal frame, holding that the precautionary principle and the polluter pays principle are part of the law of the land, to be read with Articles 21, 47, 48A and 51A(g), and that remedial costs of environmental degradation fall on the polluter. The forest bench’s continuing supervision in the Godavarman litigation from 1996, in which the Court read the word forest by its dictionary meaning and kept forest diversion under judicial oversight for decades, showed the same logic applied to the conservation statutes. The combined effect is a field in which the operative questions are as often answered by a bench as by a board, and in which the expansion of standing, which removed the requirement that a petitioner show personal injury, is the single most consequential procedural fact: it is why this body of law is litigated by citizens and organisations rather than enforced primarily by its own regulators.

How much of environmental law in India was made by judges rather than by Parliament?

A substantial and defining part. Parliament made the statutes, the boards and the offence structure, but the enforceable right to a clean environment, the precautionary and polluter pays principles as binding law, the widened standing that lets any citizen sue, and much supervision of forests and urban pollution were created by Supreme Court interpretation of Article 21, not by legislation.

None of this was in the statutes the judges were interpreting, which is why an account of Indian environmental law confined to the statute book misdescribes its own subject. The boards prosecute and consent; the courts constitutionalised. When the tribunal statute arrived in 2010 it legislated into this judge-shaped space, directing the new tribunal in Section 20 to apply the principles of sustainable development, precaution and polluter pays, which is to say Parliament codified principles the courts had already announced.

The judicial layer also explains the tribunal that eventually joined it. By the late nineteen nineties the Supreme Court was saying openly that environmental adjudication needed scientific capacity that ordinary courts lack: in the A. P. Pollution Control Board v Professor M. V. Nayudu litigation of 1999 the Court examined how other jurisdictions had built specialised environmental courts and commended the idea to the government, and the Law Commission’s One Hundred and Eighty-sixth Report of 2003 converted the suggestion into a worked proposal for environment courts with judicial and technical members. When Parliament enacted the tribunal statute in 2010 it adopted that institutional design, benches combining judicial and expert members, and routed to it the fields where scientific fact decides outcomes. The tribunal is therefore best read as the judiciary’s critique of the field’s original design, codified: the 1974 scheme assumed regulators would regulate and courts would punish, and by 2010 all three organs agreed that a fourth institution, expert and specialised, was required to make the scheme work.

Forums: where an environmental dispute is heard

The National Green Tribunal Act, 2010, Act 19 of 2010, created a specialised forum whose jurisdiction is defined by a list: Schedule I to the Act names the Water Act of 1974, the Water Cess Act of 1977, the Forest (Conservation) Act of 1980, the Air Act of 1981, the Environment (Protection) Act of 1986, the Public Liability Insurance Act of 1991 and the Biological Diversity Act of 2002, and the tribunal hears civil cases raising a substantial question relating to the environment under those enactments, together with appeals against specified orders such as consents, clearances and closure directions. The tribunal’s constitution, benches and procedure are treated in the series account of the National Green Tribunal Act; the connective point is the list itself. The two oldest conservation statutes, the Indian Forest Act of 1927 and the Wild Life (Protection) Act of 1972, are not in the Schedule, so disputes over reserved forests and protected areas travel the older road to the High Courts under Article 226, while a dispute over a consent under the Air Act or a direction under the umbrella Act goes to the tribunal, with an appeal from the tribunal lying to the Supreme Court. Section 29 of the tribunal statute bars civil courts from entertaining matters the tribunal is empowered to decide, which makes the Schedule the operative map of the forum question: the same landscape can produce two different courts depending on which statute the grievance is framed under.

Where do environmental disputes go when the National Green Tribunal cannot hear them?

To the High Courts under Article 226 of the Constitution, and in fundamental rights matters directly to the Supreme Court under Article 32. Wildlife and reserved forest disputes under the statutes omitted from the tribunal’s Schedule follow this path, as do constitutional challenges to the environmental statutes themselves, which no tribunal can decide.

The tribunal works in two jurisdictions that a reader should keep apart, because they pull different classes of grievance into the same building. In its original jurisdiction it hears applications raising a substantial question relating to the environment arising from the Schedule statutes, and may order relief and compensation to victims of pollution and other environmental damage, restitution of property damaged and restitution of the environment for the areas affected, which makes it the first Indian forum in which compensation for environmental harm is a designed remedy rather than a judicial improvisation. In its appellate jurisdiction it hears appeals against specified instruments of the administrative system: consents and their refusal, environmental clearances, closure and stoppage directions, and penalty determinations, subject to short limitation periods that reflect a legislative preference for speed and finality. The creation of this appellate path altered the behaviour of the whole administrative layer beneath it, since a board or an appraisal authority that knows its order will be tested promptly before an expert forum writes a different order from one that expects review, if any, in a distant writ court. The post-2010 field is therefore best understood as having two adjudicative storeys: the tribunal handling the statutory traffic of the Schedule Acts, and the constitutional courts handling everything else, including everything about the field’s two oldest conservation statutes, which Parliament left where the litigation of the nineteen eighties had put them.

The tribunal also closed the field’s strangest institutional episode. After Bhopal, Parliament enacted the National Environment Tribunal Act of 1995 to provide strict liability compensation for accidents involving hazardous substances through a dedicated tribunal. The Act was never brought into force: no commencement notification issued, no tribunal was constituted, and the statute sat on the book as a dead letter for fifteen years until the National Green Tribunal Act of 2010 repealed it and enacted the working version of the idea. The episode is a caution against reading the statute book as a description of the legal system: between 1995 and 2010 the book announced a compensation tribunal that did not exist, and accident victims used the ordinary courts and, for the insurance layer, the Public Liability Insurance Act instead. It also marks the limits of the field’s growth by enactment. When a design requires new institutions, money and appointments, enactment alone does not deliver them, a lesson the boards’ staffing history teaches from the other side.

The forum map reinforces the article’s central observation. Jurisdiction in this field is not organised by subject, since pollution, forests, wildlife and biodiversity plainly belong to one subject in ordinary language. It is organised by statute, and the statutes are organised by the constitutional accidents of their birth. A lawyer advising on an environmental grievance starts not from the harm but from the enactment under which the harm can be framed, and the enactment determines the forum, the remedies, the limitation period and the identity of the respondent authority.

The municipal tier

Below the states stands a third tier that the framework’s statutes mostly ignore and its grievances mostly concern. The Constitution (Seventy-fourth Amendment) Act of 1992 gave municipalities constitutional status and, through Article 243W read with the Twelfth Schedule, contemplated their responsibility for public health, sanitation conservancy and solid waste management, and for urban forestry, protection of the environment and promotion of ecological aspects. The pollution framework built in the nineteen seventies had not waited for that amendment: the Ratlam judgment of 1980 had already located an enforceable environmental duty in a municipality’s statutory obligation to provide sanitation, and municipal public health legislation across the states continues to supply the legal basis on which overflowing drains, uncollected waste, insanitary markets and stagnant water are challenged in the first instance. The solid waste rules under the umbrella Act are addressed substantially to urban local bodies, which are at once the largest generators of the compliance problem and the institutions least equipped, in finance and in engineering staff, to solve it. The connective point completes the federal picture drawn in this article. Environmental law in India is made at the Centre under routes that bypass the states, administered by boards the states appoint, and experienced by citizens at the level of a municipality that appears in none of the founding statutes and holds duties under all of them.

Environmental law at the edges of other fields

The map drawn so far has a porous boundary, and completeness requires marking the environmental law that lives inside statutes owned by other fields. The Factories Act of 1948 acquired, by an amendment of 1987 passed in Bhopal’s shadow, a chapter on hazardous processes imposing duties of disclosure, health surveillance and emergency planning on occupiers, administered by factory inspectorates rather than pollution boards. The Motor Vehicles framework carries emission norms for vehicles, set through rules that track the ambient standards system and enforced by transport authorities. The mining code conditions leases on environmental obligations that the forest and clearance regimes then operate. The atomic energy framework regulates radioactive waste through its own safety authority, outside the umbrella Act’s ordinary run. Electricity, ports, shipping and petroleum each carry environmental obligations of their own, from oil pollution liability at sea to ash utilisation duties on thermal plants imposed through notifications under the umbrella Act. The point for the whole-field reader is methodological: a search confined to statutes with environment in their titles will understate the obligations on any real facility, and the discipline of the field consists precisely in knowing which neighbouring statute books to open. It also completes the federal picture, since these edge obligations are enforced by sectoral regulators, transport departments, inspectorates and port authorities, multiplying the set of institutions a single discharge can engage.

The states as environmental legislators

The central architecture sits on top of a state layer that predates and surrounds it, and no map of the field is complete without it. States were legislating on pollution-adjacent subjects before Parliament entered the field at all: river pollution prevention legislation existed in Orissa from 1953, and Maharashtra enacted its own water pollution prevention statute in 1969, five years before the central Act it would later adopt over the top of it. State public health engineering and municipal law governed water supply, drainage and sanitation throughout, and still governs much of what residents experience as environmental failure, from a choked drain to an uncollected waste heap. Within the central framework itself, the states hold real legislative and administrative space. On Concurrent List subjects such as forests and wildlife, a state may legislate, and a state law repugnant to a central law can still prevail in that state if it has been reserved for the President’s consideration and has received assent under Article 254, clause 2, though Parliament may legislate over it again. Under the consent statutes the states hold a more basic power still: the perimeter of the Water Act in a non-adopting state is nothing, and the adoption and amendment resolutions that extend the framework come from state legislatures. Under the umbrella rules, state governments and their boards administer consents, declare silence zones and air pollution control areas, constitute the state-level clearance authorities that appraise the smaller category of projects, and frame state rules and notifications on subjects from plastic waste to sand mining. The result is that the field’s centre of legislative gravity is national but its centre of administrative gravity is state-level, and many apparent national questions, from why a consent takes the time it takes to why the same industry is conditioned differently across a state border, are answered in the state layer rather than in any central text.

The finance of the framework

Money follows the same fragmented pattern as authority. The boards were designed to be part-funded by the water cess of 1977, a levy hypothecated to pollution control, and the abolition of the cess in 2017 without a successor levy left them dependent on consent fees and budgetary support, a dependence that shapes their appetite for enforcement against the very units whose fees fund them. Polluter money enters through several channels that were never consolidated: compensation and environmental compensation deposits ordered by courts and the tribunal in individual matters, the Environment Protection Fund into which the substituted penalties of the umbrella Act are credited, and the compensatory afforestation funds accumulated under the forest clearance regime, which grew so large under court-supervised collection that Parliament eventually enacted a dedicated statute in 2016 to govern the fund’s management and release to the states. Each channel answers a different statute or a different litigation, and no channel is available for the general purposes of the system, so the field can simultaneously hold very large sums in earmarked environmental funds and field inspectorates too thin to monitor the consents on which those funds partly depend. A designed system would treat finance as part of the architecture; this system treats it, as it treats everything, as a by-product of whichever instrument created the money.

The field’s silences

What a legal field omits is as diagnostic as what it contains, and the omissions of this field follow the same route logic as its contents: subjects acquired statutes when a constitutional door and a prompting event coincided, and subjects without either remained governed by fragments. Contaminated land is the clearest silence. India has no dedicated statute for the identification and remediation of contaminated sites; polluted soil at a legacy industrial site is addressed, if at all, through the hazardous waste rules, the umbrella Act’s direction power and the polluter pays principle applied by tribunals case by case, without a register of sites, a statutory remediation standard or a fund of the kind other jurisdictions built for the purpose. Groundwater, the source on which most of Indian irrigation and much drinking water depends, has no central statute at all: extraction is governed by state groundwater Acts in some states, by model bills circulated by the Centre that many states have not enacted, and nationally by the Central Ground Water Authority, a body constituted by notification under Section 3 of the umbrella Act in 1997 after the Supreme Court pressed the government to create a regulator for a resource no statute covered. Wetlands waited until rules of 2010, replaced in 2017, for a dedicated instrument, and remain protected largely through the clearance and coastal regimes and through judicial orders in individual cases. In each instance the pattern repeats the founding pattern of the field: protection arrives late, arrives through whatever instrument lies nearest to hand, and arrives unevenly across states, because there was no moment at which the field was designed as a whole and its inventory taken.

The newest institutional layer of the field shows the architecture still reproducing itself. The air quality crisis of the National Capital Region produced, first, an authority constituted by notification under the umbrella Act in 1998 on the Supreme Court’s prompting, and then, when episodic winter emergencies outran that body’s powers, a statute of its own: the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act of 2021 created a commission with power to direct the governments and boards of the region and to override inconsistent directions within its territory. A regional problem that the State Boards were blamed for failing to solve was answered not by reforming the boards but by placing a further authority over them for one airshed, leaving the boards in place beneath it. The pattern is familiar enough by this point to state as the field’s rule of institutional change: nothing is abolished, everything is layered, and the map a practitioner must read grows one stratum deeper with each crisis.

The decriminalisation wave redraws the offence column

Between 2023 and 2024 the field’s enforcement philosophy was formally reversed, and the manner of the reversal ran, fittingly, along the old constitutional grooves. The vehicle for the Air Act and the umbrella Act was a general statute, the Jan Vishwas (Amendment of Provisions) Act, 2023, Act 18 of 2023, assented to on 11 August 2023, which amended one hundred and eighty-three provisions across forty-two Central Acts in the name of trust-based governance and the decriminalisation of minor, technical and procedural defaults. For the Environment (Protection) Act, the amendments, brought into force on 1 April 2024, replaced the imprisonment in Section 15 with a penalty of between ten thousand rupees and fifteen lakh rupees, imposed not by a criminal court after prosecution but by an adjudicating officer after inquiry, with the penalty credited to an Environment Protection Fund and appeals lying to the National Green Tribunal. For the Air Act the same pattern applied from the same date, with one significant exception: breach of the consent requirement in Section 21, establishing or operating an industrial plant in an air pollution control area without the State Board’s consent, retained criminal liability, so the gateway offence of the air regime remains a crime while its penalty offences went civil. The Indian Forest Act of 1927 and the Public Liability Insurance Act of 1991 were amended in the same statute, the former chiefly in its penalty levels.

The Water Act could not be reached by a general amending statute in the same way, because Article 252 reserves the amendment of a consent statute to the consent procedure. It was amended instead by its own measure, the Water (Prevention and Control of Pollution) Amendment Act, 2024, built on fresh resolutions passed by the legislatures of Himachal Pradesh and Rajasthan under Article 252, assented to in February 2024, and applying in the first instance to those two states and the Union territories, with other states able to adopt it by resolution, as Bihar and West Bengal have since done. Its changes mirror the umbrella pattern with additions of its own: most imprisonment provisions converted to penalties of between ten thousand rupees and fifteen lakh rupees determined by adjudicating officers, with appeals to the tribunal; violations of the consent provisions in Sections 25 and 26 keeping a criminal edge; the Central Government empowered to issue guidelines on the grant, refusal and cancellation of consents and to exempt categories of industrial plants from the consent requirement; and the manner of nominating the chairperson of a State Board made prescribable by the Centre. The mechanism’s vitality was demonstrated again when the amendment was extended to Manipur by a resolution adopted in Parliament itself, acting for a state under President’s rule, an almost laboratory-perfect display of Article 252 at work in the present decade.

The debate over this wave deserves statement at full strength on both sides, because both sides are describing the same statutes accurately. The government’s case, put by Environment Minister Bhupender Yadav in the Rajya Sabha debate on the Water Amendment Bill, was that the amended law would give impetus to industry while advancing environmental protection, that streamlining the consent mechanism and replacing imprisonment with penalties for minor defaults removed a regime in which technical lapses exposed citizens and businesses to criminal process, and that trust-based governance was the organising principle of the whole Jan Vishwas exercise. The opposing case was put in the same debate by the Trinamool Congress member Jawhar Sircar, who charged the government with the systematic decriminalisation of environmental offences in the interest of the industrial and mining lobby and warned that river pollution, including in the Ganga, would be encouraged rather than curbed, and by the Communist Party of India (Marxist) member V. Sivadasan, who pressed the federal objection that water monitoring belongs at state and local level and that the amendment weakened the state structures that do it. A third position, visible in the technical commentary on the amendments, accepts decriminalisation in principle while questioning whether adjudicating officers drawn from the administration and penalties capped at fifteen lakh rupees can deter a large industrial polluter for whom compliance capital expenditure runs into crores.

The verdict this article reaches is that the wave is best understood not as the weakening of a working criminal regime but as a change in where power over enforcement sits. The criminal provisions being repealed were, in the pollution field, rarely prosecuted to conviction: prosecution required board sanction, trials were slow, and the threat of imprisonment functioned more as negotiating leverage in consent proceedings than as an operating sanction. Measured against actual practice, the deterrent lost is smaller than the rhetoric on both sides suggests. What is not rhetorical is the relocation of discretion. Penalties are determined inside the executive by adjudicating officers rather than by courts; consent guidelines and exemptions issue from the Centre rather than being embedded in state practice; the nomination of state chairpersons becomes centrally prescribable. Read through the lens of this article’s argument, the wave continues the field’s founding pattern: the formal text of the statutes changes less than the identity of the institution empowered to decide, and the direction of travel in 2023 and 2024 was from courts and states toward the Centre and its officers.

Two boundaries of the wave should be fixed, since they are often misstated. The first is what it did not touch. The Wild Life (Protection) Act was not among the statutes the Jan Vishwas Act amended, and its principal offences continue to carry imprisonment; the wave was a pollution-law event, not a general pardon across the environmental field, and the conservation statutes stand where they stood. The second is escalation. The Jan Vishwas Act builds in an automatic increase of fines and penalties by ten per cent of the minimum amount at the expiry of every three years from its commencement, an unusual provision that hard-wires penalty inflation into the substituted regime and partly answers the objection that fixed monetary ceilings decay in real terms. The deeper design question the wave leaves open is institutional: adjudicating officers are executive appointees deciding penalties under statutes administered by the same executive, and the tribunal’s appellate docket will be the test of whether that arrangement produces consistent, reviewable decisions or merely faster ones.

The resulting offence map of the field is a two-track system, and the tracks correspond to the field’s two halves. On the criminal track stand the conservation statutes and the gateway offences of the pollution statutes: hunting and trade offences under the wildlife statute with their substantial imprisonment terms, the slender but criminal penalty of the forest conservation statute, operating without consent under the Air Act’s Section 21 and the Water Act’s Sections 25 and 26 in the states that have taken the 2024 amendment. On the civil track stand the offences of standards and procedure: exceeding an emission or effluent limit, failing a reporting or authorisation condition, contravening the umbrella Act or its rules, and, since its own amendment of 2023 substituted penalties for imprisonment, contraventions of the diversity statute as well, all punishable by adjudicated monetary penalty, credited in the umbrella Act’s case to a dedicated fund, with the tribunal as the appellate check. Whether a given act of pollution is a crime or a billing event therefore depends on which statute it is charged under and, for water, on which state it occurred in and whether that state has adopted the amendment, a dependence that would be indefensible in a designed system and is unremarkable in this one. It is the offence-column expression of the article’s thesis: the route and the decade of a statute still decide the legal character of identical conduct.

The accountability the architecture produces

A structure built this way distributes accountability in a pattern worth naming, because it explains the tone of public argument about the field. When a river stretch is found unfit for bathing, the state government can point to the central statute and the central standards; the Centre can point to the State Board that consents and inspects; the Board can point to its sanctioned strength and its budget, both set by the state; and the tribunal or the High Court, moved by residents, becomes the venue in which the circle of pointing is interrupted by a direction. Each participant’s account is, within its own frame, accurate, and that is the problem: the architecture was assembled in a sequence that never assigned end-to-end ownership of any environmental outcome to any institution. The pollution boards own consents but not ambient quality; the ministry owns standards but not inspection; the state owns the board but not the statute the board administers; the courts own the right but not the machinery. Environmental federalism of this accidental kind has one genuine virtue, which is redundancy: a failure at one level can be corrected at another, as the entire litigation history of the field demonstrates, since grievances blocked in the boards have repeatedly been carried to the courts and grievances the courts could not manage were eventually given a tribunal. Its cost is the diffusion of blame that every actor in the system has learned to use. Reform proposals that do not address this assignment problem, however elegant their institutional diagrams, leave the essential feature of the field untouched.

Two standard arguments, tested against the architecture

The first standard argument holds that India has strong environmental laws that are weakly enforced. Its evidence is real. The consent system in the Water and Air Acts is detailed and demanding on paper; the umbrella Act’s powers of closure and standard-setting are sweeping; the boards that must operate all of it are, in most states, thinly staffed, technically stretched and nominated through political processes; monitoring data are sparse beside the size of the regulated economy; and the criminal sanctions that gave the paper strength were seldom carried through. Stated this way the argument is broadly right, and any honest account of the field must keep its central observation intact. But it is incomplete in a way the architecture exposes. It assumes the strength is in the laws, as a legislative settlement, and the weakness is in administration, as an accident of capacity. The structure described in this article shows something different: Parliament chose, in 1986 and in every rules cycle since, to locate the substantive standards of the field in delegated legislation that the executive can rewrite without a vote. The severity of the operative law at any moment is therefore not a fixed legislative inheritance that administrators fail to honour; it is a setting the executive itself chooses, and when an exemption is notified for a category of projects or a standard is relaxed by amendment of a schedule, that is not weak enforcement of a strong law. That is the law being changed by its custodian. The dilution-by-notification critique, documented amendment by amendment over the years by research organisations such as the Centre for Science and Environment in New Delhi, which has tracked how successive revisions of the clearance notification have widened exemptions and softened appraisal, is on this structural point simply accurate, and the strong-law framing survives only when it is confined to the skeleton of the Acts rather than the flesh of the rules.

The second standard argument runs the other way: that environmental regulation obstructs development, that clearance timelines are unpredictable, that appraisal by committee substitutes amateur judgment for expertise, and that capital is deterred by the cumulative burden of environmental clearance, forest clearance, consents and wildlife approvals running on separate tracks. This argument also has real evidence behind it, and the architecture explains where it bites. A project that needs forest land faces the Section 2 gate of the 1980 Act; a project in a listed category faces environmental clearance under the 2006 notification; the same project faces consent to establish and consent to operate from the State Board; and each process has its own committee, its own conditions and its own appeal path. The strongest version of the development critique is not that any one of these gates is illegitimate but that the gates were never designed as a system, because they were built by different statutes under different routes across three decades, and no proponent can discover from the law itself the full list of permissions a project requires. Against it stands the evidence that delay concentrates in state-level processing and in deficient project documentation rather than in the statutory gates as such, and the further observation that the system’s unpredictability is aggravated less by stringency than by reopenability: a clearance granted after appraisal can be challenged before the tribunal, conditions can be revisited, and long-running judicial supervision can alter the terms of a project years after investment has been committed. A strict standard applied predictably is a cost an investor can price. A moderate standard applied unpredictably is a risk an investor cannot. On the evidence of the architecture itself, uncertainty, generated by multiplicity of forums and instruments rather than by the height of any standard, is the larger burden of the two, and reforms aimed at the burden would be aimed at consolidation of process and finality of decision rather than at dilution of standards.

The state’s own reform practice acknowledges the multiplicity problem while treating it as a processing problem rather than a legal one. Successive governments have layered administrative consolidation over the statutory multiplicity: a single-window clearance portal, launched in 2018 under the name PARIVESH, through which environmental, forest, wildlife and coastal clearances are applied for and tracked on one interface, with standardised forms and timelines for appraisal committees. The portal is a real mitigation of the proponent’s burden and no mitigation at all of the lawyer’s point, which is that behind the single window stand the same separate statutes, committees and appeal routes, each with its own conditions capable of independent challenge. Administrative integration of this kind is the characteristic reform of the field in its maturity: because the statutory architecture cannot be rebuilt without running the constitutional routes again, reform energy flows into the layer that can be changed by decision, the process layer, exactly as substantive severity flows through the layer that can be changed by notification. Both tendencies confirm the structural reading offered in this article.

The consolidation question

The obvious response to an architecture like this is to ask why it has never been replaced by a designed one, and the question has been asked officially twice. The Law Commission of India, in its One Hundred and Eighty-sixth Report of 2003, proposed the constitution of specialised environment courts, reasoning that environmental disputes required a forum combining legal and scientific competence; the National Green Tribunal of 2010 was the eventual, partial answer, a tribunal rather than a court, confined to a statutory list. A decade later the high level committee chaired by the former Cabinet Secretary T. S. R. Subramanian, constituted in August 2014 to review the six principal environmental laws and reporting on 18 November 2014, proposed the full consolidation: a new umbrella statute, the Environmental Laws (Management) Act, subsuming the existing laws, with a National Environment Management Authority and State Environment Management Authorities as full-time expert bodies granting single-window, time-bound clearances, the existing boards absorbed into them, and an environment reconstruction cost charged to projects and accumulated in a dedicated fund. The report was attacked by environmental organisations and opposition parliamentarians as a clearance-first exercise conducted at speed, was examined without enthusiasm in the parliamentary committee process, and was not carried into legislation.

The Subramanian episode is instructive beyond its fate, because the obstacles to consolidation are structural and this article’s argument identifies them. A single code would have to repeal or absorb statutes standing on incompatible foundations. Repealing a Concurrent List statute is within Parliament’s ordinary competence, and amending a treaty statute raises no federal difficulty, but the Water Act and the Wildlife Act in their original application rest on state consent, and Article 252, clause 2, confines their amendment and repeal to the like manner, so a consolidating Parliament must either re-run the consent process state by state or leave the consent statutes standing beside the code it has just proclaimed universal. Consolidation also threatens every interest that has learned to work the multiplicity of the system: ministries that administer separate gates, boards whose jurisdiction would be absorbed, and appraisal structures whose informality is a feature to their users. The field therefore changes the way it has always changed, at the edges and through the instruments that need no one’s consent: a notification here, an adjudicating officer there, a tribunal list lengthened or left alone. The architecture of 1972 to 1986 is not awaiting replacement. It is the permanent frame within which replacement proposals are negotiated down to amendments.

The committee’s proposals were followed by a draft Environment Laws (Amendment) Bill circulated by the ministry in 2015, which drew the same objections in stronger form and was not introduced in Parliament. The episode completed a pattern the field had already established with the Law Commission’s courts proposal, which took seven years to arrive in attenuated form as the tribunal: in this field, institutional redesign is repeatedly proposed, repeatedly trimmed, and finally enacted, if at all, as the smallest change that does not disturb the existing distribution of jurisdiction.

Treaty commitments keep arriving

The Article 253 door through which the Air Act and the umbrella Act entered has remained open, and later treaty commitments have continued to be implemented through the framework rather than beside it. The Montreal Protocol on ozone-depleting substances was given effect through the Ozone Depleting Substances (Regulation and Control) Rules of 2000, made under the umbrella Act: a global phase-out schedule thus entered Indian law as a set of rules administered by an ozone cell in the ministry, without a dedicated statute. The biodiversity statute of 2002 answered the Rio convention of 1992 by the opposite method, a full Act with its own authorities, showing that the choice between an Act and a notification remained open and was made case by case. The field’s largest subject, climate change, has been governed almost entirely without legislation: the National Action Plan on Climate Change of 2008 and its missions are executive policy, international commitments under the Paris Agreement are implemented through targets, schemes and the energy statutes of another field, and proposals for a framework climate law have remained proposals. For the connective argument of this article the pattern is the point. New environmental subjects do not disturb the architecture; they are poured into it, and the vessel they are poured into, Act, rules, notification or policy, is chosen for administrative convenience under the routes the Constitution happens to make available, exactly as it was in 1972.

How to read this field

For the compliance reader, the practical map is the sequence of gates: identify the statutes engaged by the activity, which for most industry means the Water and Air consents first, the umbrella rules for the relevant waste streams and processes second, an environmental clearance if the project is in a listed category, and a forest or wildlife approval if the land or the location brings those statutes in; then identify the deciding institution for each gate, which in the pollution field will almost always be the State Board of the state where the plant stands. For the researcher, the primary materials repay reading in an order most guides do not suggest: the preambles of the four founding statutes, which confess their constitutional routes in their first paragraphs, then the extent clauses, then the deeming provisions of the Air Act, then the rules and notifications in which the operative obligations live, and only then the case law that constitutionalised the field. Keeping such a file in order, with the notifications and amendments that silently change the operative law preserved alongside the Acts they amend, is the working habit on which sound commentary in this field depends, much as the source material behind an investigation is preserved by the methods journalists use to keep a protected, verifiable research file in VaultBook. For the examination candidate, the examinable core is exactly the spine of this article: Articles 252 and 253, Entries 17, 17A and 17B and Entry 6, Articles 48A and 51A(g), the board structure, the tribunal’s Schedule, and the 2023 and 2024 decriminalisation amendments. The account given here is a statement of the general law and its structure; it is legal information, not advice on any individual matter, and a person facing a specific consent, clearance or prosecution question needs advice taken on the facts of that case in the state concerned.

The questions on which the framework’s next shape turns are likewise structural rather than rhetorical, and they can be read off the architecture. How many states adopt the Water Amendment of 2024, and on what timescale, will measure whether the consent route still functions as a living federal instrument or has become a formality performed by two states and a Parliament acting for a third. Whether adjudicating officers build a body of reasoned, consistent penalty decisions, and whether the tribunal’s appellate scrutiny disciplines them, will decide whether the civil track of the offence map acquires the legitimacy the criminal track never quite achieved. Whether the standards and exemptions in the rules universe continue to move at notification speed, in both directions, will determine how much of the field’s real content remains, in substance, executive law. And whether any future consolidation proposal confronts the consent basis of the founding statutes, rather than drawing institutional diagrams over it, will show whether the lesson of 1972 has been learned by the field’s reformers as thoroughly as it has been learned by its historians.

The verdict on the whole field follows from its foundations. Indian environmental law is not a strong code weakly administered, and it is not a paper tiger either. It is a group of statutes of genuinely different constitutional character, assembled in the order in which constitutional doors opened between 1972 and 2003, sharing one set of boards because the boards happened to be built first, and governed in its daily operation by executive instruments that no legislature voted on line by line. Its uniformity is a rumour; its reach, its offences, its forums and its standards all vary by statute, by state and by notification. The route determined the reach, and it still does: when Parliament amended the water statute in 2024 it reached, from long habit and constitutional necessity, for the resolutions of state legislatures, fifty years after it first did so. A reader who keeps that single fact in hand can navigate the entire field, because every peculiarity of Indian environmental law, from the factory’s consent file to the tribunal’s Schedule, is downstream of it.

Frequently Asked Questions

Q: Which laws make up India’s environmental legal framework?

The framework has five layers. The constitutional layer consists of Article 48A, clause (g) of Article 51A and the judicial reading of Article 21. The statutory layer contains the Indian Forest Act of 1927, the Wild Life (Protection) Act of 1972, the Water (Prevention and Control of Pollution) Act of 1974 with its Cess Act of 1977, the Forest (Conservation) Act of 1980, the Air (Prevention and Control of Pollution) Act of 1981, the Environment (Protection) Act of 1986, the Public Liability Insurance Act of 1991, the Biological Diversity Act of 2002 and the National Green Tribunal Act of 2010. The third layer is the rules and notifications under the 1986 Act, covering impact assessment, coastal zones and every major waste stream. The fourth is institutional: the pollution control boards, the biodiversity authorities and the forest administration. The fifth is adjudicatory: the tribunal and the constitutional courts.

Q: Does the Constitution protect the environment?

Yes, but through provisions of different strengths rather than through a single environmental clause. The original Constitution of 1950 said nothing on the subject. The Forty-second Amendment of 1976 inserted Article 48A, directing the state to endeavour to protect and improve the environment and to safeguard forests and wildlife, and clause (g) of Article 51A, making protection of the natural environment a fundamental duty of every citizen. Neither provision is directly enforceable, since directive principles and fundamental duties are not justiciable. The enforceable protection arrived through interpretation: the Supreme Court read the right to life in Article 21 as including a right to a wholesome environment, and Articles 48A and 51A(g) are regularly cited in support of that reading. Protection therefore exists, is real in litigation, and rests on a judicial construction built over two non-justiciable texts.

Q: How did the 42nd Amendment change environmental competence?

It redistributed legislative power over two subjects and added the Constitution’s only environmental texts. Forests moved from Entry 19 of the State List to Entry 17A of the Concurrent List, and protection of wild animals and birds moved from Entry 20 of the State List to Entry 17B of the Concurrent List, so Parliament acquired power to legislate on both subjects for the whole country without seeking state resolutions, subject to the repugnancy rule in Article 254. The amendment also inserted Article 48A in the directive principles and clause (g) in the fundamental duties in Article 51A. Its limits are as instructive as its changes. Water remained in Entry 17 of the State List, so the Water Act continued to depend on Article 252 and to require the consent procedure for amendment. The wildlife statute, by contrast, became freely amendable by Parliament once its subject had moved, and its later amendments ran nationally.

Q: Why were the Water and Air Acts enacted under different constitutional provisions?

Because the subjects stood in different places when each Act was passed, and the available door differed. Water was a State List subject under Entry 17, read with public health in Entry 6, and Parliament had no ordinary power over it, so the Water Act of 1974 was enacted under Article 252 on the resolutions of twelve state legislatures, applying at first to those states and the Union territories and spreading by adoption. The Air Act of 1981 was enacted under Article 253 as legislation implementing the decisions of the Stockholm conference of 1972, a power that lets Parliament legislate for the whole territory of India without state consent, so the Air Act extended to the whole of India from commencement. The difference reflects the distribution of subjects and the timing of each statute, not a judgment that water mattered less than air.

Q: Who enforces environmental law in India?

Enforcement is divided among institutions matched to the statutes. The State Pollution Control Boards are the front-line regulators for pollution: they grant and refuse consents under the Water and Air Acts, inspect premises, take samples, issue closure and disconnection directions, and launch prosecutions or penalty proceedings. The Central Pollution Control Board co-ordinates them, develops standards, runs national monitoring and may direct them under Section 18 of the founding Acts. The Central Government and the environment ministry enforce the Environment (Protection) Act, issue directions under Section 5 and run the clearance system through appraisal committees and state-level authorities. Forests and wildlife are enforced by the forest departments and Chief Wildlife Wardens, biodiversity by the National Biodiversity Authority and State Biodiversity Boards, and sanitation and waste duties fall heavily on municipalities. The National Green Tribunal and the courts adjudicate and supervise; day-to-day enforcement belongs to the boards and departments named here.

Q: Is there a right to a clean environment in India?

Yes. The right is not written in the Constitution in those words; it is a judicial construction of Article 21, which guarantees that no person shall be deprived of life or personal liberty except according to procedure established by law. In Subhash Kumar v State of Bihar in 1991 the Supreme Court held that the right to life includes the right of enjoyment of pollution-free water and air for the full enjoyment of life, and that a petition under Article 32 may be filed to enforce it. The directive in Article 48A and the duty in Article 51A(g) are read in support. In Vellore Citizens Welfare Forum in 1996 the Court added the operative principles, holding the precautionary principle and the polluter pays principle to be part of the law of the land. The right is therefore enforceable in the Supreme Court and the High Courts, and its content has been built case by case.

Q: Why do most environmental rules sit outside the Acts?

Because the framework was designed that way. The Environment (Protection) Act of 1986 is an enabling statute: Sections 3, 6 and 25 give the Central Government power to set standards, restrict activities and make rules for carrying out the Act, and the operative detail of the field, emission and effluent limits, clearance procedures, waste handling conditions, was deliberately placed in that delegated layer. Technical standards need revision as processes, fuels and knowledge change, and subordinate legislation can be amended by notification in the Gazette far faster than Parliament can amend an Act. The consequences are structural. Most of the obligations an operator must obey are found in schedules, rules and notifications rather than in any Act; Parliament’s control is exercised through the laying requirement rather than through debate on each instrument; and the severity of the regime can be raised or lowered by the executive without fresh primary legislation.

Q: Which environmental laws apply to a small factory?

The core set is the consent pair and the umbrella rules. The factory needs consent to establish and consent to operate from its State Pollution Control Board under Sections 25 and 26 of the Water Act if it will discharge sewage or trade effluent, and under Section 21 of the Air Act if it is in an air pollution control area and will emit into the atmosphere; the board classifies it by pollution potential, and white-category units are exempted from consent in many states. Under the Environment (Protection) Act it must comply with the applicable emission and effluent standards and, if it generates hazardous waste, hold an authorisation under the hazardous waste rules, with the other waste rules applying by stream. An environmental clearance is needed only if the unit falls within a listed category and threshold of the impact assessment notification, which most small units do not. If it handles notified hazardous substances above threshold quantities, the Public Liability Insurance Act requires an insurance policy.

Q: Can a state withdraw from an Act Parliament passed under Article 252?

No. Article 252 is a one-way door. Clause 2 of the article provides that an Act passed under it may be amended or repealed only by an Act of Parliament passed in like manner, meaning through the same resolution procedure, and not by an Act of the state legislature. A state that has consented, or that has later adopted the Act by resolution, cannot withdraw its consent, cannot repeal the Act for its own territory and cannot legislate inconsistently to displace it. The state’s leverage exists at two moments only: before consent, when it may refuse to pass the resolution and stay outside the Act, and at the point of amendment, when fresh resolutions are the vehicle Parliament uses, as the Water (Amendment) Act of 2024 used the resolutions of Himachal Pradesh and Rajasthan. Once inside, the state is governed by the central text like any other part of the Act’s territory.

Q: What is the difference between environmental clearance and consent to operate?

They are permissions under different statutes, from different authorities, at different stages of a project’s life. Environmental clearance is a prior approval under the environmental impact assessment notification of 2006, issued under the Environment (Protection) Act, required only for projects in listed categories; it is granted by the environment ministry or a state-level authority after screening, impact study, public consultation and appraisal, and it decides whether the project may be set up at that location and on what conditions. Consent to operate is a permission from the State Pollution Control Board under Section 25 of the Water Act and Section 21 of the Air Act, granted after consent to establish and after construction, verifying that effluent treatment and emission control arrangements are installed and that the unit can meet the applicable standards. Clearance addresses the project’s predicted impact; consent addresses the plant’s actual pollution control readiness, and a project that needs both must obtain them in that order.

Q: What is the difference between the Central Pollution Control Board and the State Pollution Control Boards?

The two tiers were both created by the Water Act of 1974 and divide national from field functions. The Central Pollution Control Board, constituted under Section 3 in September 1974, is the national body: it advises the Central Government, co-ordinates the State Boards and may direct them under Section 18, develops standards and national monitoring programmes, and publishes the technical data of the field. The State Pollution Control Boards, constituted under Section 4 by the state governments, do the regulating on the ground: they receive consent applications, inspect industries, sample discharges and emissions, issue directions including closure, and initiate prosecution or penalty proceedings. Chairpersons and members of each board are nominated by the government that constitutes it, the Centre for the Central Board and the state for a State Board. By Sections 3 and 4 of the Air Act, the same two tiers are deemed to be the boards under that Act as well, so no parallel air boards exist.

Q: Do the Water and Air Acts still matter after the Environment Protection Act?

Yes; the umbrella Act supplemented them and did not replace them. The Environment (Protection) Act of 1986 nowhere repeals the Water Act of 1974 or the Air Act of 1981, and the consent system through which industry is licensed continues to run entirely under the older pair, administered by boards that owe their existence to the Water Act. Section 24 of the umbrella Act gives its provisions overriding effect where another enactment is inconsistent, while providing that conduct punishable under both the umbrella Act and another law is punished under the other law, a formula that assumes the older statutes continue to operate. The division of labour is functional: the older Acts govern consents, board powers and medium-specific offences for water and air, while the umbrella Act supplies general standard-setting, the rules universe, the Section 5 direction power and coverage of subjects, from hazardous waste to coastal zones, that the older pair never reached.

Q: Why is environmental litigation in India dominated by public interest litigation?

Because the procedural design of the field invites it and the regulatory design made it necessary. Public interest litigation relaxed the rule of standing, so a petitioner need not show personal injury: a letter from a public-spirited person or organisation can be treated as a writ petition, and environmental harm, which is typically diffuse, falling on a river, a forest or a neighbourhood rather than on one owner with a measurable loss, fits that procedure exactly. The harm was also framed constitutionally, since after Subhash Kumar pollution is an Article 21 violation maintainable directly in the Supreme Court under Article 32 and in the High Courts under Article 226. On the other side, the statutory enforcement channel was narrow: prosecution under the founding Acts required the sanction of a board, boards were thinly staffed, and trials were slow. Litigants therefore carried environmental questions to the constitutional courts, and the doctrines, closures and supervisory regimes of the field were built there, in cases such as the M. C. Mehta series.

Q: Can a state make environmental laws stricter than the central law?

Generally yes in application, with formal limits on legislation. Three routes exist. Under the Water and Air Acts, State Boards set the conditions of each consent and may impose standards and conditions stricter than the national floor where local conditions require it, so stringency is routinely raised unit by unit without any new law. On Concurrent List subjects such as forests and wildlife, a state legislature may enact a law that departs from the central law if the state law is reserved for the President’s consideration and receives assent under clause 2 of Article 254, in which case it prevails in that state until Parliament legislates over it. State governments also make stricter rules and notifications in the spaces the central framework leaves them, on subjects from plastic to mining. The asymmetry is consistent: a state may tighten the regime within its territory through these routes, but it may not dilute a central standard, and under an Article 252 statute it may not amend the central Act at all.

Q: What triggered India’s modern environmental legislation?

The proximate trigger was the Stockholm conference of June 1972, the United Nations Conference on the Human Environment, at which India participated at the level of its Prime Minister and from which it returned committed to legislating. The Wild Life (Protection) Act followed within months in 1972 and the Water Act in 1974, both built on state resolutions under Article 252. The second trigger was constitutional: the Forty-second Amendment of 1976 moved forests and wildlife to the Concurrent List and inserted Articles 48A and 51A(g). The third was catastrophic: the Bhopal gas disaster of December 1984 produced the general Environment (Protection) Act of 1986 under the treaty power of Article 253, since a general law could not have been built on state consent at the speed required. Each layer of the framework thus answers an event: a conference, an amendment and a disaster, and the framework’s untidy shape is the record of those three occasions rather than of any single plan.

Q: Why did India decriminalise most environmental offences?

The stated reason was proportionality within a policy of trust-based governance. The Jan Vishwas (Amendment of Provisions) Act of 2023, which carried the change for the Air Act and the Environment (Protection) Act, proceeded on the ground that imprisonment for minor, technical and procedural defaults was disproportionate, deterred ordinary business activity and clogged courts, and that monetary penalties fixed by adjudicating officers would be faster, more certain and more collectable; the Water (Amendment) Act of 2024 applied the same reasoning to water. There was also a practice-based argument: criminal prosecution under the pollution Acts required board sanction, moved slowly and rarely ended in conviction, so the imprisonment being removed had functioned mainly as background leverage in consent negotiations. The change was contested in Parliament, where opposition members argued that replacing imprisonment with capped penalties diluted deterrence and favoured industrial polluters, and that objection, and the adjudicating officer design, remain the live points of dispute about the reform.

Q: What is the difference between forest clearance and environmental clearance?

They authorise different things under different instruments. Forest clearance is the prior approval of the Central Government required by Section 2 of the Forest (Conservation) Act of 1980 before forest land may be dereserved or used for a non-forest purpose such as mining, a dam, a road or a factory; it is advised on by the Forest Advisory Committee and is normally conditioned on compensatory afforestation and payment of the net present value of the diverted forest. It answers one question: may this forest land change use. Environmental clearance, under the impact assessment notification of 2006 made under the Environment (Protection) Act, appraises the project itself, its emissions, effluents, waste, water use and ecological effects, after impact study and public consultation, and answers a different question: may this project proceed at this location and on what environmental conditions. A mining project on forest land needs both, in sequence, and neither approval substitutes for the other.

Q: Who sets pollution standards in India?

Standard-setting is shared among three levels, with the Centre holding the pen for most numerical limits. The Central Government lays down standards under Sections 3 and 6 of the Environment (Protection) Act, and the schedules to the Environment (Protection) Rules carry the general and industry-specific emission and effluent standards, while ambient standards, such as the National Ambient Air Quality Standards revised in 2009, are notified under the same umbrella. The Central Pollution Control Board develops and recommends the technical content, co-ordinates uniformity among states and issues classifications and directions. Under the Water and Air Acts the boards themselves hold standard-related functions, and State Boards translate the national standards into consent conditions for each unit and may tighten them for local conditions. The practical position is that a factory’s binding numbers appear in its consent, which applies national standards developed through the central board system and notified by the Central Government, adjusted where the state board requires more.

Q: Why does the same activity face different environmental rules in different states?

Several independent causes stack. The founding statutes do not run identically everywhere: the Water Act is a consent statute whose text can differ between a state that adopted the 2024 amendment and one that has not, so the same discharge can be a criminal offence on one side of a border and a penalty matter on the other. Administration is state-level: State Boards fix consent conditions, validity periods, fees and inspection practice, declare air pollution control areas and silence zones, and impose stricter conditions where they judge local conditions to require them. State governments add their own rules and notifications on subjects the framework leaves open, from plastic and sand mining to siting restrictions, and legislate on Concurrent List subjects within the assent procedure. Finally the umbrella rules are national, but their appraisal and enforcement machinery is state-level for the smaller project categories. Uniformity in this field is a property of some texts, not of the system, and the variation is a designed consequence of its federal construction.

Q: Who should a resident approach about pollution from a nearby factory?

The first door is the State Pollution Control Board of the state where the factory stands. A written complaint to the Board, or through its grievance channels, can trigger inspection and sampling, and the Board holds the powers that matter most at that stage: it can enforce the factory’s consent conditions, issue directions including closure and disconnection of electricity and water, and initiate prosecution or penalty proceedings. The district administration and the municipality are the doors for the nuisance and sanitation aspects of the same facts. If the complaint is not acted on, two formal routes open. Under Section 19 of the Environment (Protection) Act, a citizen who has given sixty days’ notice of the intended complaint to the government or the Board may file a complaint before a court for offences under that Act. For matters under the statutes in the National Green Tribunal’s Schedule, including the Water and Air Acts, an application to the tribunal can seek closure, compensation and restoration of the affected environment.
