State reorganisation in India rests on a single constitutional fact that most public argument about new states never reaches. The political map of the Union is not fixed by the units themselves. Parliament may form a new state out of the territory of an existing one, merge two states into one, enlarge or shrink a state, move its boundaries, or change its name, and it may do all of this by an ordinary law passed by a simple majority of members present and voting. The state whose territory is taken, divided, or renamed must be asked for its views. It cannot refuse. Its legislature’s opinion, however strongly expressed, is advice that Parliament is free to set aside, and on the one occasion when a state assembly formally rejected the very Bill that divided it, in January 2014, Parliament proceeded and the division took legal effect five months later.

That design is the subject of this guide. The articles that follow it in this series take up the individual statutes one by one: the great settlement of 1956, the three creations of 2000, the bifurcation of Andhra Pradesh in 2014, and the conversion of Jammu and Kashmir in 2019. This article does the connective work. It states the constitutional provisions exactly as they stand, explains the two conditions the Constitution attaches to their use and the judicial decisions that fixed what those conditions mean, traces the commissions whose reports shaped the map, and then takes apart a reorganisation Act itself, head by head, because the political drama of a division lasts a season while the administrative instrument that carries it out governs the successor states for generations. The disputes that fill the years after a new state appears, over assets, officers, river waters, court records, and institutions, are almost never disputes about whether the division should have happened. They are disputes inside the ten or so standard heads that every reorganisation Act must settle, and a reader who understands those heads understands where reorganisation is actually fought.

The namable claim of this article can be stated in one sentence. In India, the internal map is the least constitutionally entrenched part of the constitutional order: it can be redrawn by the weakest legislative instrument the Constitution knows, an ordinary law, and the Constitution says in terms that such a law is not even an amendment of the Constitution. Everything else in this field, the commissions, the agitations, the litigation, the decades of unfinished division work, is commentary on that sentence.

The constitutional power behind state reorganisation in India: Articles 1 to 4

The starting point is Article 1. India, that is Bharat, is declared to be a Union of States, and the territory of India comprises the territories of the states, the Union territories, and such other territories as may be acquired. The states and Union territories are not listed in the operative text of the article itself. They are specified in the First Schedule, which is a table that legislation can rewrite. The architecture matters. The Constitution does not define India by enumerating sovereign units that pre-exist it and whose boundaries it guarantees. It defines a Union, and then keeps the list of the Union’s component units in a schedule designed to be amended by the very power that the next two articles confer.

Article 2 deals with the outside edge of the Union. Parliament may by law admit into the Union, or establish, new states on such terms and conditions as it thinks fit. This is the provision for territory that is not already part of India: a foreign territory that accedes, or a territory acquired by India, enters the Union through Article 2. Its use has been rare and its most consequential modern instance, the integration of Sikkim, was carried through with constitutional amendments in 1974 and 1975 because Sikkim’s entry carried special terms that were written into the Constitution itself as Article 371F. The distinction between Article 2 and Article 3 is the distinction between enlarging the Union from outside and rearranging it from within, and confusing the two is the first error in most popular writing on this subject.

Article 3 is the working provision, and it deserves to be set out by its operations rather than paraphrased. Parliament may by law, first, form a new state by separation of territory from any state or by uniting two or more states or parts of states or by uniting any territory to a part of any state; second, increase the area of any state; third, diminish the area of any state; fourth, alter the boundaries of any state; and fifth, alter the name of any state. Two explanations widen the reach of the text. The first provides that in these five clauses the word “State” includes a Union territory, so that Parliament may carve a state out of a Union territory, or territory out of a Union territory to join to a state, under the same power. The second provides that the power to form a new state includes the power to form a new state or a new Union territory by uniting a part of one state or Union territory to another. Nothing in the article requires that the resulting units be viable, contiguous, linguistic, or consented to. The article states a power and two conditions, and the conditions are procedural only.

The first condition is that no Bill for the purpose shall be introduced in either House of Parliament except on the recommendation of the President. In the constitutional scheme, where the President acts on the aid and advice of the Council of Ministers, this condition means in substance that a reorganisation Bill is a government measure. A private member may demand a new state on the floor of the House every session for a decade, as members from the regions demanding statehood regularly do, but the Bill that divides a state can only enter Parliament as the Union government’s own proposal. The second condition is the one that generates the recurring misconception this article exists to correct. Where the proposal in the Bill affects the area, boundaries, or name of a state, the President shall refer the Bill to the legislature of that state for expressing its views thereon within such period as may be specified in the reference, or within such further period as the President may allow. The state legislature must be asked. The text then stops. It does not say that the views must be favourable, or that they must be obtained before Parliament may act beyond the initial reference, or that a failure to respond blocks anything. The period may expire in silence, and Parliament may legislate.

Article 4 completes the design and contains its most striking provision. A law made under Article 2 or Article 3 shall contain such provisions for the amendment of the First Schedule and the Fourth Schedule as may be necessary to give effect to it, and may also contain such supplemental, incidental, and consequential provisions, including provisions as to representation in Parliament and in the legislatures of the affected states, as Parliament may deem necessary. Then comes the declaration: no such law shall be deemed to be an amendment of this Constitution for the purposes of Article 368. The consequence is that a statute which rewrites the list of states, reallocates seats in the Council of States, reconstitutes legislative assemblies, and moves millions of people from one unit of the federation to another is, in the Constitution’s own classification, ordinary legislation. It is passed by the majority that passes a railway budget demand. It needs no special majority of two-thirds, no ratification by half the states, and no ceremony beyond the ordinary passage of a Bill followed by presidential assent.

The supplemental and consequential power in Article 4 is the quiet workhorse of the whole design, and it has been read broadly. A reorganisation law may reach beyond the two Schedules and make the provisions that the event of a division renders necessary across the statute book: adapting references in other laws, constituting authorities for the transition, validating things done in anticipation, and settling representation in bodies other than Parliament. When the Punjab Reorganisation Act was challenged on the reach of such a provision, the Supreme Court in Mangal Singh v. Union of India, decided in 1967, sustained the Act and treated the power to make supplemental, incidental, and consequential provisions as a real legislative power ancillary to the reorganisation, not a formula to be read down to nothing. The boundary the cases imply is one of nexus: the provision must serve the reorganisation, not use the reorganisation as a vehicle for unrelated legislation. Within that boundary, a single ordinary law can do everything a division requires, which is precisely the draftsman’s intention. The map changes, the schedules change, the statute book is conformed, the assemblies and courts are reconstituted, and all of it travels in one instrument passed by the majority of the day.

Why did the framers withhold a consent requirement?

Because the map they inherited was provisional in every direction and a consent right would have frozen it. The units of 1950 were accidents of conquest, treaty, and accession rather than expressions of settled political identity, and a Constituent Assembly that expected wholesale redrawing wrote a power to redraw, not a right to refuse.

The units it inherited in 1949 were an accident of conquest, annexation, and negotiation: British provinces drawn for imperial administration, and more than five hundred princely states integrated into the Union through instruments of accession and merger agreements in the space of about two years. A constitution that had frozen that map behind a consent requirement would have entrenched lines that almost nobody in the Assembly believed were rational, and would have handed every provincial government a veto over the correction of boundaries it had not itself drawn.

Dr B. R. Ambedkar, introducing the Draft Constitution in November 1948, drew the contrast with the American federation in terms that have organised the debate ever since. The American Union, he argued, was indissoluble but its states were also indestructible, because the federation rested on a compact among sovereign units that retained their integrity against the centre. The Indian Union was to be indissoluble without its units being indestructible: the country was one integral whole, its people a single people, and the division into states existed for the convenience of administration. The phrase that has attached itself to his argument, an indestructible Union of destructible states, is a summary rather than a quotation, but it captures exactly what Articles 3 and 4 enact. The Union cannot be dissolved by the secession of any unit. The unit can be dissolved by the Union acting through Parliament.

There was also a harder-edged reason, which the subsequent history of reorganisation has repeatedly vindicated as a description of the problem, whatever view a reader takes of the solution. If the consent of the affected state were required, a region seeking separation from a state whose majority opposed it could never obtain separation at all. The Telugu-speaking districts of Madras could not have left Madras with the Madras legislature’s consent. Telangana could not have left Andhra Pradesh with the undivided assembly’s consent, and in fact that assembly resolved against the division. The hill districts of Uttar Pradesh could not have become Uttarakhand over Lucknow’s objection. A consent rule is, in this setting, not a neutral federal courtesy. It is a decision that the existing majority of a state holds a permanent veto over the political future of every minority region within it. The framers chose the other decision, and the choice is the whole subject of the controversy section later in this article.

What happens if a state legislature does not respond?

If the period the President’s reference specifies expires without a reply, the constitutional condition stands satisfied and Parliament proceeds exactly as if views had been received. Silence is not a veto, an assent, or a ground of challenge; the reference exists to inform Parliament, and an unanswered reference informs it completely.

The reference goes to the state legislature with a period specified by the President, and the President may allow a further period. If the legislature expresses no views within the period as extended, the condition in the proviso stands satisfied and Parliament may proceed exactly as if the views had been received and considered. Silence is not a veto, a delayed response is not a veto, and an express rejection is not a veto either: all three are inputs into a parliamentary decision that the Constitution reserves to Parliament. The proviso creates a right to be heard, structured as a reference with a time limit, and the time limit is the tell. A consultation whose responses can be outwaited is a consultation designed to inform the deciding body, not to share the decision with the consulted body.

In practice the reference has produced every possible outcome except a change in who decides. State legislatures have endorsed proposals, have rejected them, have returned them with conditions, and have on occasion not taken them up within the period. The Andhra Pradesh legislature debated the bifurcation Bill in January 2014 and the Legislative Assembly adopted a resolution rejecting it, a step its supporters described as the state’s answer and its critics described as constitutionally beside the point. Both descriptions were accurate. The answer was given, as the proviso requires, and it was then set aside, as the proviso permits.

The road a reorganisation travels, from demand to appointed day

The constitutional text describes the last stage of a reorganisation. The road that leads there is longer, and most of it is travelled outside Parliament. A claim begins as a movement or an electoral promise. It is examined, if the Union government of the day is willing to examine it, through the instruments the record has made standard: a committee or commission of inquiry, a resolution of the affected state legislature where the legislature is willing, ministerial negotiation with the region’s representatives, and, at the drafting stage, an inter-ministerial exercise in which the schedules of the future Act, its territories, institutions, and service lists, are assembled. The Andhra Pradesh division shows the full sequence in modern form. The demand for Telangana was examined by the Committee for Consultations on the Situation in Andhra Pradesh, chaired by Justice B. N. Srikrishna, which reported in December 2010 with a set of options rather than a single recommendation. A Group of Ministers worked on the terms of division in the autumn of 2013. The Union Cabinet approved the creation of Telangana, the President referred the Bill to the state legislature in December 2013 with a period for its views that was extended once, the Assembly resolved against the Bill on 30 January 2014, and Parliament enacted it in February. Nothing in that sequence except its last steps is constitutionally required. All of it is politically characteristic. The power is exercised in a burst of legislation, but it is prepared, when it is prepared at all, over years.

The steps that are constitutionally required have a fixed order, and each has a small jurisprudence or practice of its own. The Union Cabinet decides. The President’s recommendation is obtained, which in practice means the Bill is settled by the government before any legislator sees it. If the proposal touches the area, boundaries, or name of a state, the President refers the Bill to that state’s legislature and specifies the period for its views, a period measured in weeks rather than months: six weeks is the span the record shows for the reference of 2013, and the power to extend it rests with the President. The state legislature debates and answers, or does not. The Bill is then introduced in either House, debated, and passed by simple majority in each. Where the state is under President’s rule, the reference and the legislative functions of the state travel an unusual road, since Parliament itself assumes the state legislature’s powers, a configuration the 2019 reorganisation used and the subsequent challenge placed at the centre of argument. Assent follows, and the Act then waits for its appointed day, notified separately, while the machinery of division is assembled: committees for the allocation of employees, experts for the apportionment of assets, and the cadre-controlling authorities for the All India Services. The interval between assent and the appointed day is when a reorganisation is actually built. The Act’s text is its blueprint, and the interval is the construction site, and the history of the field suggests that reorganisations succeed or fail in the interval more than in the debate.

One feature of the road deserves emphasis because it explains the shape of the politics. At no point does the process contain a moment at which the people of the affected territory vote on the proposal. There is no referendum, no plebiscite, and no requirement of a resolution from the districts concerned. The wishes of the people enter the process as evidence, through movements, elections, and the state legislature’s expressed views, but they never enter it as a decision. There is one luminous exception, and it proves the rule by having been arranged outside the Constitution’s own machinery. When the future of Goa was contested in the 1960s, between merger with Maharashtra and continuation as a Union territory, the question was put to the people of Goa in an opinion poll held on 16 January 1967, the only popular vote of its kind in the history of Indian reorganisation. The voters chose continued Union territory status over merger, and the verdict was honoured: Goa remained a territory for twenty further years, until statehood in 1987 settled the question the other way. The poll was a political device created for the occasion by the Union government, not a step in any statutory procedure, and it bound nobody in law. Its singularity is the datum. In the one case where the people of a territory were asked directly, they were asked by grace, and their answer was respected by the same discretion that had granted the asking. Defenders of the design note that the state legislature’s debate is the people’s forum and that a referendum on boundaries would import into the Constitution a device it uses nowhere else. Critics note that on the most consequential question a citizen can face, which state they belong to, the citizen is the only participant in the scheme who is never asked in a form that binds. Both observations are accurate, and the choice between them is the consent debate taken up later in this article, stated at the level of procedure where it begins.

What the courts have fixed, and the one thing Article 3 cannot do

The meaning of the consultation condition was settled early, in litigation arising out of the 1956 settlement itself, and the settlement has never since been disturbed. The States Reorganisation Bill as introduced had proposed that the old Bombay state be replaced by three units: a state of Maharashtra, a state of Gujarat, and the city of Bombay as a separate unit. The Bill was referred to the Bombay legislature, which expressed its views. Parliament then changed its mind in the course of passage and enacted instead a single enlarged bilingual state of Bombay, combining the Marathi-speaking and Gujarati-speaking areas that the original proposal had separated. A challenge followed in Babulal Parate v. State of Bombay, decided by the Supreme Court in 1960, on the ground that the Act as passed embodied a proposal different from the proposal referred, and that a fresh reference to the state legislature was therefore necessary before Parliament could enact it.

The Court rejected the argument, and its reasoning defines the consultation requirement to this day. The proviso obliges the President to refer the proposal contained in the Bill as introduced. It does not require that every amendment moved and carried during the Bill’s passage through Parliament be sent back for a fresh expression of views, for that would make parliamentary deliberation impossible: a legislature that could reopen the reference at every amendment would hold a continuing suspensive power over the Bill. Amendments made in Parliament must satisfy a discipline of relevance: an amendment must be germane to the subject matter of the original proposal, and it must not be a direct negative of that proposal. Judged by that test, forming one composite state where three units had been proposed was germane to the subject of reorganising the Bombay region and was not the negation of the proposal to reorganise it. The Court also observed that the validity of parliamentary proceedings could not in any event be questioned on the ground of an alleged irregularity of procedure, a bar that Article 122 places around the internal working of Parliament. The combined effect is that the consultation happens once, at the threshold, on the proposal in the Bill as introduced, and thereafter the Bill belongs to Parliament.

One boundary of the power is equally well settled, and it cuts in the opposite direction. Article 3 governs the internal rearrangement of the Union’s territory. It does not empower Parliament to give Indian territory away. When the Nehru-Noon Agreement of 1958 between India and Pakistan required the transfer of a part of the Berubari Union in West Bengal to Pakistan, the President referred the question to the Supreme Court under Article 143, and in its advisory opinion In re Berubari Union, delivered in 1960, the Court held that the power to diminish the area of a state under Article 3 does not extend to ceding Indian territory to a foreign state. Cession alters the territory of India itself as described in Article 1, and it can be effected only by a constitutional amendment under Article 368. The Ninth Amendment of 1960 was enacted to implement that agreement. The same route was taken more than half a century later when the Constitution (One Hundredth Amendment) Act, 2015 gave effect to the Land Boundary Agreement with Bangladesh and the exchange of enclaves between the two countries: an ordinary reorganisation law was not enough, because the external boundary of the Union moved. The rule of thumb is clean. Within the frontier, Parliament’s power over the map is as wide as legislative power gets. At the frontier, it stops, and the amendment procedure takes over.

A second boundary is worth stating because it is the one the 2019 reorganisation pressed against. Article 3 speaks of forming states and altering states, and the first explanation extends its clauses to Union territories for most purposes. Whether the power includes converting a state into a Union territory, downgrading a full unit of the federation into a centrally administered territory, was the question placed before the Supreme Court in the challenge to the Jammu and Kashmir Reorganisation Act, 2019. The five-judge Constitution Bench that decided the Article 370 case on 11 December 2023 upheld the creation of the Union territory of Ladakh and upheld the abrogation of the state’s special position, but it did not decide the conversion question. The Solicitor General had assured the Court that statehood would be restored to Jammu and Kashmir, and on the strength of that assurance the Court recorded that it was not called upon to adjudicate whether a state may be converted into a Union territory, while directing that statehood be restored at the earliest opportunity and that elections to the Legislative Assembly be held by 30 September 2024. The legal consequence is precise and should be stated without embellishment: the widest question about the reach of Article 3 remains open, undecided by the only court that can settle it, and any account that reports it as decided, in either direction, is wrong.

The courts’ role in this field is therefore best described as policing edges. The Supreme Court has decided the meaning of the proviso in Babulal Parate, the outer limit of the power in Berubari, and, in the Article 370 case, the questions it chose to reach while expressly leaving the conversion question open. Below the constitutional level, the original jurisdiction of the Supreme Court under Article 131, which covers disputes between states, is the forum in which the unfinished business of reorganisation is litigated: Maharashtra’s suit over Belgaum is one instance, and the river-water and boundary suits between successor states are others, though water disputes travel their own statutory road to tribunals under Article 262 and are treated in their own articles in this series. What no court has ever done is undo a reorganisation. No Act under Article 3 has been struck down, no appointed day has been rolled back, and no successor state has been remerged by judgment. The pattern is consistent with the text: a power conferred in the widest terms, with two procedural conditions, leaves a court very little to hold on to, and the challenges that have succeeded in this field have succeeded on the conditions and the edges, never on the merits of the line drawn. A reader assessing a future challenge should therefore ask the narrow questions first: was the recommendation obtained, was the reference made where the proviso required it, does the law stay within the frontier, and does it collide with some other provision of the Constitution. The broad question, whether the division was wise or just, is one the constitutional scheme reserves to Parliament and to the electorate that judges Parliament.

How does India compare with other federations?

India stands at the permissive end of the federal range. The United States and Australia make the affected state’s consent a textual condition of boundary change, and Germany requires a referendum in the territories concerned, while India requires consultation without consequence, leaving Parliament’s power over the map limited mainly by politics.

The comparison explains why foreign descriptions of Indian federalism so often reach for qualifiers. In the United States, Article IV of the federal Constitution provides that no new state shall be formed or erected within the jurisdiction of any other state, nor any state be formed by the junction of two or more states or parts of states, without the consent of the legislatures of the states concerned, as well as the consent of Congress. The consent of the affected state is a textual condition, and boundaries settled under it are correspondingly hard to move. In Australia, section 123 of the Commonwealth Constitution requires both the consent of the parliament of the affected state and the approval of a majority of that state’s electors voting on the question before the state’s limits may be altered. Germany’s Basic Law, in Article 29, routes the reorganisation of the Länder through a federal law confirmed by referendum in the territories concerned. The pattern across the classic federations is consistent: the units are constitutionally protected against the centre in their territorial integrity, and the protection usually combines legislative consent with, in some systems, a popular vote.

India chose none of these devices. There is no consent clause, no referendum requirement, and no ratification. The political scientist K. C. Wheare, whose taxonomy shaped the comparative study of federalism, described the Indian Constitution as quasi-federal, a system federal in form with a strong unitary tilt, and the territorial provisions are the clearest exhibit for his label. Granville Austin, the historian of the Constituent Assembly, read the same design more sympathetically as part of a cooperative federalism adapted to a country whose unity could not be assumed. The two descriptions disagree about the design’s merits. They do not disagree about what the design is. The units of the Indian Union hold their boundaries at the pleasure of Parliament in a way that the states of the United States, the Australian states, and the German Länder do not, and every reorganisation since 1950 has been an exercise of that pleasure, whether the affected legislature welcomed the result or resolved against it.

The commissions that shaped the map

Because the power is so wide, the politics of reorganisation has largely been the politics of persuading the Union government to use it, and the characteristic instrument of persuasion has been the commission of inquiry. Three bodies frame the whole story, and their reports, read in sequence, show the Union arguing with itself about whether language should organise the map at all.

The first was the Linguistic Provinces Commission, appointed in June 1948 by Dr Rajendra Prasad, the President of the Constituent Assembly, and chaired by S. K. Dar, a retired judge of the Allahabad High Court. The commission was asked whether new provinces should be formed on a linguistic basis, and its report, submitted on 10 December 1948, answered that they should not. It recommended that provinces be reorganised on grounds of geographical contiguity, financial self-sufficiency, and administrative convenience rather than language, and it warned that provinces formed on a primarily linguistic basis would not serve the larger interests of the nation at a moment when national unity was fragile. The Congress party, confronted with the strength of the reaction, appointed its own committee at its Jaipur session in December 1948, composed of Jawaharlal Nehru, Vallabhbhai Patel, and the Congress president Pattabhi Sitaramayya, and known by the initials of its members as the JVP Committee. Its report of 1 April 1949 reached substantially the same conclusion. Language was formally rejected as the basis for reorganisation, the creation of new provinces was said to be inopportune, and the committee recommended that the question be deferred. Between them, the two reports represented the settled view of the national leadership in the first years of the republic: linguistic states were a demand to be managed, not a principle to be enacted.

What broke the settlement was not argument but sacrifice. The demand for a Telugu-speaking state carved out of Madras had been pressed for years, and in October 1952 Potti Sriramulu, a veteran of the freedom movement, began a fast in support of it. He died in December 1952 after a fast lasting nearly two months, and the disturbances that followed his death made the existing position untenable. The Union government announced the formation of Andhra State within days, and on 1 October 1953 the Telugu-speaking districts of Madras became the first state of the Indian Union formed on a linguistic basis, with its capital at Kurnool. The creation of Andhra State did not rest on any commission’s recommendation. It demonstrated, to every other region with a linguistic or regional claim, exactly what the route to statehood looked like, and the claims multiplied accordingly.

The Union government’s response was to return to the commission device, this time at full scale. The States Reorganisation Commission was appointed in December 1953, chaired by Fazl Ali, a former judge of the Supreme Court, with H. N. Kunzru and K. M. Panikkar as its members. It toured the country, received representations on a very large scale, and submitted its report on 30 September 1955. The report’s enduring significance lies in the balance it struck. It accepted language as a legitimate and important factor in drawing state boundaries, and to that extent reversed the Dar and JVP positions. It refused the doctrine of one language, one state, insisting that language was one factor among several, to be weighed against the unity and security of the country, financial viability, administrative convenience, and the wishes of the people concerned, and it warned against treating linguistic homogeneity as an end in itself. It recommended a map of sixteen states and three Union territories. The government accepted the report with modifications, and its framework, enacted the following year, drew most of the map that India still uses. The detailed working of that enactment, the states it created and the ones it refused, and the Seventh Amendment that accompanied it, are the subject of the article on the States Reorganisation Act 1956, to which this guide links the reader for the depth this survey cannot hold.

What the government did with the Fazl Ali report is as instructive as the report itself, because the gap between a commission’s map and the enacted map is where the politics of the design shows. The Commission recommended sixteen states and three Union territories. The Act produced fourteen states and six Union territories. The Commission’s treatment of the west coast proposed a Maharashtra that included Vidarbha, a Gujarat, and the city of Bombay held apart as a separate unit, a solution designed to give each language region its state while keeping the great bilingual port city out of either’s hands. The government, after the Bill’s introduction and reference had run their course, enacted instead the composite bilingual Bombay that Babulal Parate later challenged, folding Vidarbha into it and keeping Bombay city within it. The Commission had recommended that Vidarbha might stand as a state of its own if its people wished, and Vidarbha’s advocates have treated that passage as an unredeemed promise ever since. Belgaum, which the Commission left with the Kannada-speaking state after weighing the city’s mixed character and its district’s administration, became the border dispute that has outlived the Commission by seventy years. The pattern generalises. A commission’s report is the most respectable form in which a reorganisation proposal can arrive, and it is still only advice, to a government that may accept its framework and rearrange its conclusions, exactly as a state legislature’s views are advice to a Parliament that may accept the framework of a reference and legislate against its answer. At every level of this field, the deciding body asks and the asked body advises, and the identity of the decider, not the quality of the advice, is what the Constitution settles.

The grounds on which states have actually been made

The Constitution prescribes no criterion for reorganisation. Article 3 does not mention language, culture, size, viability, or consent, and Parliament has never bound itself by a statutory test. What the record shows instead is a succession of grounds, each dominant in its period, which a reader of demands should learn to identify, because the ground on which a state is claimed usually predicts the shape of the Act that creates it.

Language was the ground of the first settlement and the one the commissions argued about. It organised the map of peninsular and western India in 1956 and completed itself in 1960 and 1966. Its strength as a criterion was administrative as much as cultural: a state whose government, courts, and schools work in the language its people speak is a state whose citizens can reach it. Its weakness appeared at every border it drew, because language regions shade into one another and no line can follow a gradient. The Fazl Ali Commission’s refusal of the one language, one state formula was a refusal to pretend otherwise.

Identity distinct from language supplied the second ground. Nagaland was created not because the Naga hills spoke one language, for they speak many, but because a political settlement with the Naga movement required a state as its instrument. Meghalaya was carved from Assam for the Khasi, Jaintia, and Garo hills, Jharkhand for the tribal plateau of southern Bihar after a movement that had run since the early twentieth century, and Mizoram and Arunachal Pradesh through the graduation of hill territories whose administration from a plains capital had always been an anomaly. In each of these the operative fact was a people’s claim to govern itself in a territory it regarded as its own, and the reorganisation Act functioned as the legal form of a political compact.

Administrative size supplied the third ground, and it carried the creations of 2000. Uttar Pradesh, Madhya Pradesh, and Bihar were the three largest states of the Union, and the regions that left them, the hill districts of the north-west, the forested east of Madhya Pradesh, and the plateau of the south Bihar, each argued that a distant and enormous state government could not attend to them: that development funds, administrative attention, and political representation all thinned with distance from the capital. The argument is empirical and its evidence is contested in each case, but as a ground it has a distinctive feature its advocates prize. It asks for no cultural separateness at all, only governability, and it therefore travels across party lines in a way identity claims do not.

A word belongs here about the evidence on which these grounds are judged, because it is weaker than the confidence of the arguments suggests. Linguistic claims rest on census returns of mother tongue, and those returns are answers to a question put by an enumerator, shaped by what the respondent believes the answer will accomplish. In Punjab before the 1966 division, the language question in the census of 1961 became a field of the larger conflict itself, with large numbers of respondents returning a language aligned with their religious community rather than with the speech of their homes, and the commission appointed in 1966 under Justice J. C. Shah to demarcate the Punjabi-speaking and Hindi-speaking areas had to build its line from tehsil-level returns whose infirmity everyone acknowledged. The Shah Commission’s work is the honest emblem of the field’s evidentiary problem. The Constitution asks Parliament to draw lines through populations, and the data from which lines are drawn are themselves political acts. Every commission since Dar has known this, and the better reports say so, which is one reason the better reports treat language as a factor to be weighed rather than a boundary to be traced.

Economic grievance supplied the fourth ground, and it is the ground of the Telangana movement in its modern phase: the claim that a region contributes more to the state’s revenues than it receives, that its water is allocated away from it, and that its share of public employment is smaller than its share of population. The triad of funds, water, and jobs was the movement’s stated case, and the case was disputed on every element by the defenders of the undivided state, who pointed to the integrated development of the capital city and the costs a division would impose on both successors. This guide does not adjudicate those figures, which remain contested between the successor states in the working out of the 2014 Act itself. It notes the form of the ground, because a division argued on economics produces an Act whose contested heads are predictable in advance: the schedules of institutions, the apportionment of debt, the sharing of river waters, and the allocation of employees are exactly where the Telangana argument said the injury lay, and they are exactly where its aftermath has been fought.

The waves of reorganisation after 1956

The settlement enacted by the States Reorganisation Act, 1956 (Act 37 of 1956), which took effect on 1 November 1956 and organised the country into fourteen states and six Union territories, was presented as a conclusion. It functioned instead as a beginning. The mechanism the Constitution supplied, an ordinary law on a commission’s or a movement’s prompting, remained available for every claim the 1956 settlement had refused, deferred, or created, and the decades since have used it in recognisable waves.

The map the 1956 Act enacted on 1 November 1956 deserves a sentence of its own, because later reorganisations are best read as amendments to it. There were fourteen states: Andhra Pradesh, Assam, Bihar, Bombay, Jammu and Kashmir, Kerala, Madhya Pradesh, Madras, Mysore, Orissa, Punjab, Rajasthan, Uttar Pradesh, and West Bengal, and six Union territories, among them Delhi, Himachal Pradesh, Manipur, and Tripura. Three features of that map contained the seeds of the next seventy years. Punjab was left undivided, although the demand for a Punjabi-speaking state had been pressed throughout the Commission’s inquiry and refused, partly because the language returns in Punjab had become entangled with religious identity in ways that made a linguistic line unusually hard to draw honestly. The north-east was left substantially within an enlarged Assam, although the hill peoples of the region had never been administered as one with the plains in any earlier dispensation, and the Commission expected the arrangement to be revisited. And Bombay was left bilingual, against the grain of the principle the Act embodied everywhere else. Each of the three features was a deferral dressed as a decision, and each was revisited within sixteen years.

The first wave completed the linguistic logic that 1956 had left unfinished. The bilingual Bombay state, the settlement’s most unstable product, lasted less than four years: after sustained agitation in both language regions, the Bombay Reorganisation Act, 1960 (Act 11 of 1960) divided it with effect from 1 May 1960 into Maharashtra and Gujarat. Nagaland followed a different route to the same destination: the State of Nagaland Act, 1962 carried statehood for the Naga Hills with effect from 1 December 1963, the product of a negotiated settlement between the Government of India and the Naga People’s Convention rather than of a linguistic claim. Punjab, which the 1955 Commission had kept undivided, was reorganised by the Punjab Reorganisation Act, 1966 (Act 31 of 1966) with effect from 1 November 1966: the Hindi-speaking areas became the new state of Haryana, the hill areas were transferred to the Union territory of Himachal Pradesh, and Chandigarh was made a Union territory and the shared capital of both successor states. Himachal Pradesh itself moved from Union territory to state under the State of Himachal Pradesh Act, 1970, with effect from 25 January 1971.

The second wave redrew the north-east and admitted the remaining outliers. The North-Eastern Areas (Reorganisation) Act, 1971 (Act 81 of 1971), effective from 21 January 1972, made Manipur, Tripura, and Meghalaya full states and constituted Mizoram and Arunachal Pradesh as Union territories, breaking up the old Assam into units that reflected the region’s distinct peoples rather than a single provincial frame. Sikkim entered by the amendment route in two steps, first as an associate state under the Thirty-fifth Amendment in 1974 and then as a full state under the Thirty-sixth Amendment with effect from 16 May 1975, its terms of entry preserved in the Constitution itself. In 1987 the process of elevation continued: Mizoram and Arunachal Pradesh became states on 20 February 1987, and Goa became a state on 30 May 1987 under the Goa, Daman and Diu Reorganisation Act, 1987 (Act 18 of 1987), with Daman and Diu remaining a Union territory. Each of these changes used the same ordinary legislative machinery, and each illustrates a different trigger: language, tribal self-government, negotiated peace settlements, and the graduation of territories that had been administered from Delhi.

The third wave was the creation of three states in a single month of 2000, each carved from a large Hindi-speaking state whose hill or tribal regions had sought separation for decades. The Madhya Pradesh Reorganisation Act, 2000 (Act 28 of 2000) created Chhattisgarh from 1 November 2000; the Uttar Pradesh Reorganisation Act, 2000 (Act 29 of 2000) created Uttaranchal, renamed Uttarakhand in 2007, from 9 November 2000; and the Bihar Reorganisation Act, 2000 (Act 30 of 2000) created Jharkhand from 15 November 2000. These divisions were, by the standards of this field, consensual: the legislatures of the parent states had themselves passed resolutions favouring the creations, and the Union government of the day had committed to them. They stand in the record as the clearest modern instance of Article 3 used as an instrument of accommodation, and their supporting Acts are examined together in the article devoted to the creations of 2000.

The fourth wave returned to the contested mode. The Andhra Pradesh Reorganisation Act, 2014 (Act 6 of 2014), which received assent on 1 March 2014 and took effect on the appointed day of 2 June 2014, divided Andhra Pradesh to create Telangana, the twenty-ninth state, after a movement for separation that had run, in its modern phase, for over a decade and a half. Hyderabad was made the common capital of both states for ten years. The parent state’s assembly had rejected the Bill that the President had referred to it, and Parliament enacted it regardless, passing the Bill in the Lok Sabha on 18 February 2014 and in the Rajya Sabha on 20 February 2014. The full anatomy of that statute, its schedules of divided institutions, and its contested promises are taken up in the article on the Andhra Pradesh Reorganisation Act 2014.

The fifth wave broke the pattern of the previous seventy years in a single respect that matters more than any other. The Jammu and Kashmir Reorganisation Act, 2019 (Act 34 of 2019), assented to on 9 August 2019 and effective from the appointed day of 31 October 2019, did not create a new state or elevate a territory. It took an existing state and converted it into two Union territories, one of Jammu and Kashmir with a legislature and one of Ladakh without, reducing the number of states in the Union from twenty-nine to twenty-eight. Every previous exercise of the reorganisation power since 1950 had moved a unit upward in status or rearranged units of equivalent status. This one moved a unit downward, and it was done while the state was under President’s rule, so that Parliament itself performed the functions of the state legislature whose views the proviso contemplates. The constitutional challenge that followed, and the Supreme Court’s treatment of the conversion question in December 2023, are addressed in the article on the Jammu and Kashmir Reorganisation Act 2019 and in this guide’s discussion of the courts.

The Bill in Parliament: debate under pressure

Because a reorganisation Bill needs only ordinary majorities, its parliamentary history turns on the Union government’s command of its own benches and its management of the affected members, and the passage of the contested Bills has repeatedly been the most disorderly chapter of the story. The division of Andhra Pradesh is again the fullest modern record. The Bill’s introduction in the Lok Sabha on 13 February 2014 was met with protests inside the chamber that culminated in a member discharging pepper spray, an incident that suspended members and filled the following days’ reporting. Its passage in the Lok Sabha on 18 February took place by voice vote amid continuous uproar, with the live telecast of the proceedings interrupted, officially through a technical failure, an interruption the opposition treated as deliberate and the government as accidental. The Rajya Sabha passed the Bill two days later after a debate in which the Prime Minister gave assurances to the residuary state from the floor of the House. None of this affected the Act’s validity, and the episode deserves its place in a thematic account for exactly that reason. It demonstrates the practical meaning of the procedural design: once the Cabinet has decided and the reference has been made, the remaining obstacles to a reorganisation are political management problems, soluble by a determined government within a single session, and no disorder in the chamber, no rejection by the affected legislature, and no assurance given or withheld in debate writes itself into the statute. What writes itself into the statute is the text the government drafts, which is why this article has insisted that the schedules, not the speeches, are where a reorganisation is decided.

Reorganisation while a state is under President’s rule

The hardest configuration of the power arises when the affected state has no government of its own in office. Under Article 356, when the President is satisfied that a state’s government cannot be carried on in accordance with the Constitution, the functions of the state government may be assumed by the President and the powers of the state legislature made exercisable by Parliament. A reorganisation carried out in that interval presents a double appearance. The reference the proviso requires is made to a legislature whose powers Parliament is exercising, and the law that divides the state is passed by a Parliament that is, for the time being, also the state’s legislature. The state is, in form, both consulted and divided by the same body.

This is not a hypothetical. The reorganisation of 2019 was carried out while Jammu and Kashmir was under President’s rule, its assembly dissolved, and the absence of an elected state government to receive the reference or express the territory’s views was among the principal grounds of the constitutional challenge. The Constitution Bench in December 2023 declined to hold that the Union is confined, during President’s rule, to reversible or routine measures, and it treated the exercise as within the powers the Constitution confers for such an interval, while the assurance on restoration of statehood removed the further question from decision. The position that results should be stated exactly. No decided case forbids a reorganisation during President’s rule, and the one great instance of it has survived challenge on the grounds the Court reached. The objection that survives is political and structural rather than doctrinal: that the proviso’s consultation, thin as it is when a legislature sits, becomes a consultation of the Union with itself when it does not, and that a power designed for a federation of functioning states operates differently, whatever its formal validity, when one of the states has been temporarily absorbed into the Union’s hands. Readers of the cluster’s later articles will find the 2019 article taking up the instance in full; this guide records the configuration because any future use of it will be argued from the 2019 precedent, and the precedent is narrower than either its celebrants or its critics sometimes suggest.

The voter and the franchise in a division

The citizen meets reorganisation first as a voter, and the Acts make careful provision for the meeting. Electoral rolls are territorial documents, and when territory moves, the rolls move with it: a voter enrolled in a constituency that passes to a successor state is a voter of that state from the appointed day, without any act of enrolment of their own. Sitting legislators are allotted by the same logic, as the representation head described, so that the assembly of each successor begins life composed of the members the undivided electorate returned for its constituencies. Where a general election falls near a division, the machinery adapts in the other direction. In 2014 the elections to the assemblies of Andhra Pradesh and Telangana were held in April and May of that year, constituency by constituency for both successors, before the appointed day had arrived, and the two assemblies stood duly constituted on the appointed day itself under the Act’s deeming provision, so that neither state spent a day without an elected legislature in being. The device is worth noticing for what it reveals about the design’s priorities. The Act treats democratic continuity as an engineering requirement of the same order as the continuity of laws and courts, to be provided for in advance, and the citizen’s experience of the largest change the Constitution permits to their political identity is therefore, at the level of the franchise, no experience at all: the polling station does not move, the ballot is familiar, and only the name of the state at the head of the result has changed.

The Union territory in the scheme

No account of the map is complete without the category that stands beside the state. The Union territories are administered by the President through an administrator, under Part VIII of the Constitution, and their legislative arrangements vary by design: most have no legislature at all, while a small number have been given legislatures of limited competence by constitutional provision or parliamentary law. In the history of reorganisation the category has performed three distinct functions. It was, first, a waiting room. Territories whose statehood was anticipated but deferred, Himachal Pradesh, Manipur, Tripura, Goa, Mizoram, and Arunachal Pradesh among them, were held as Union territories or their Part C predecessors while the Union judged their readiness, and the graduation from territory to state became a standard career for a unit of the federation. It was, second, a solution for places the Union wished to hold directly: the national capital, the island territories, and Chandigarh, whose status as a Union territory and shared capital was the compromise of 1966 between two states that each claimed it. It was, third, after 2019, a destination in the downward direction, the status into which a state was converted. The first two functions treat the category as an antechamber to statehood or a deliberate exception to it. The third treats it as a rank below statehood to which a state can be reduced, and it is the novelty of that treatment, more than the conversion of any particular state, that the undecided constitutional question is about. A reader should also note what the category does to the citizen. A resident of a Union territory without a legislature has no state legislature at all: their laws are made by Parliament, their administration answers to the Union Home Ministry, and their representation in the Council of States depends on the Fourth Schedule’s small allocations for such territories. The distance between that position and statehood is the distance the conversion question measures.

Three operations, three different politics

It clarifies the record to separate the operations the power performs, because they differ in everything except the section of the Constitution that authorises them. The first operation is creation by division, the classic case, in which a state is split and both parts continue as states. The second is elevation, in which a Union territory becomes a state, as Himachal Pradesh did in 1971, Manipur, Tripura, and Meghalaya did in 1972 through the fuller route of the 1971 Act, and Goa did in 1987. Elevation changes the unit’s own status without taking territory from a neighbour, and it is characteristically uncontested by anyone outside the territory: no existing state loses anything it values, and the debate is between the territory and the Union alone. The third operation is the one 2019 introduced into practice, conversion downward, in which a state becomes a Union territory or two, and the political valence reverses again: the unit affected loses status, its legislature’s powers contract to the Union territory pattern or vanish, and the change is experienced within the territory as a demotion imposed from outside. The text of Article 3 does not rank these operations or surround the third with any additional condition. The practice of seventy years had treated elevation and division as the whole field. Whether conversion stands on the same legal footing as the rest is, as this article has recorded, a question the Supreme Court was asked and, in December 2023, did not answer.

Between these large operations sits a quieter class of change that the same power performs without drama: the adjustment of boundaries between willing states and the alteration of names. Boundary alteration Acts, such as the Bihar and Uttar Pradesh (Alteration of Boundaries) Act, 1968 and the Haryana and Uttar Pradesh (Alteration of Boundaries) Act, 1979, have settled riverine and enclave disputes between neighbours by agreement, moving villages across a line to follow a river’s course or a settled consensus, with the consent of both legislatures in practice though the Constitution never required it. Name changes are the lightest exercise of all. The Madras State (Alteration of Name) Act, 1968 gave Tamil Nadu its name; the Uttaranchal (Alteration of Name) Act, 2006 restored Uttarakhand; and the Orissa (Alteration of Name) Act, 2011, with a companion constitutional amendment for the language’s name, made Odisha. Each was an ordinary law under the same article that divided Andhra Pradesh. The uniformity of the instrument across matters so different in weight is itself a datum about the design: the Constitution grades its procedures by subject, demanding special majorities for amendments and ratification for federal changes, and it placed the redrawing of the federal map, from a village boundary to the extinction of a state, in the lowest grade it has.

The capital question

Every division poses one question that the standard heads do not list and every successor must answer in bricks: where the new state is to be governed from. The Constitution does not require a reorganisation Act to name a capital, and the Acts generally do not, leaving the choice to the successor government, with the consequences that capitals are chosen by politics and sometimes left provisional for decades. The three creations of 2000 show the range. Raipur and Ranchi were substantial cities of the old states and became capitals without controversy. Uttarakhand was given Dehradun as an interim capital on its creation, the question of a permanent seat was referred in time to a commission, and the high Himalayan township of Gairsain, favoured by the statehood movement as the symbol of the hills’ claim, was declared the state’s summer capital twenty years after statehood, with the permanent question managed rather than closed. The interim capital that becomes permanent by inertia is a recognised figure in this field, and its opposite is the capital built from nothing, of which Amaravati, begun by the residuary Andhra Pradesh after Hyderabad’s loss and redesigned, halted, and revived with changes of government, is the largest and most expensive example.

The 2014 Act is again the exception that illuminates the rule, because it did legislate about a capital, and legislating about a capital turned out to mean legislating about the most valuable urban land in either successor. Hyderabad was declared the common capital of Telangana and Andhra Pradesh for a period of ten years from the appointed day, a device with no exact precedent at that scale, under which the city lay within Telangana’s territory while serving as the seat of both governments, its administration in the common period given special arrangements under the Governor’s oversight. The device bought the residuary state a decade in which to build elsewhere, and it created a decade in which the location of institutions, from the secretariat to the Raj Bhavan, was a standing subject of negotiation between the successors. Chandigarh is the older and darker version of the same device without a term: a city built as Punjab’s capital, made a Union territory in 1966 and the joint capital of both successors, promised to Punjab by the accord of 1985, claimed sentimentally by Haryana as its creation too, and retained in suspense ever since. The two cases state the rule of this section between them. A common capital with a term expires and forces the question. A common capital without one becomes the question, permanently.

The fiscal afterlife of a division

A reorganisation Act divides a balance sheet as surely as a map, and the balance sheet is where the successors meet each other for years. The public debt of the old state is apportioned between them, ordinarily in the ratio of their populations, as are its financial assets, its investments, and its guarantees. The population ratio is the field’s default rule because it is the only rule that is both simple and defensible, but it fits awkwardly where the debt was incurred for assets that sit in one successor’s territory, or where the revenue base that serviced the debt is unequally divided. The 2014 division is the standing illustration of the awkwardness. The residuary state of Andhra Pradesh kept the larger share of population and of debt, while the capital city whose taxes had serviced the whole, Hyderabad, went to Telangana, subject to the ten-year common capital arrangement. The argument that followed, about whether the apportionment should follow population, revenue, or the location of the assets the debt had built, is the fiscal form of the original political argument, conducted in the vocabulary of schedules.

Two further mechanisms belong to the fiscal afterlife. The first is the Finance Commission. Devolution from the Union to the states is recommended for five-year periods for the states as they stand, and a division in the middle of a period requires the award to be reworked between the successors, which the 2014 Act expressly provided for by requiring consultation with the Finance Commission on the apportionment of revenue shares. The second is the cost of the new capital. A successor that loses the old capital must build the apparatus of a state, its assembly, secretariat, High Court buildings, and official housing, in a place that may have none of them, and the Union has repeatedly been drawn into funding that construction, whether by promise in debate, by provision in the Act, or by grants after it. The 2014 Act declared the Polavaram irrigation project a national project and committed the Union to its execution, an instance of the general pattern in which the price of a division is partly nationalised. None of these matters appears in the slogans of a statehood movement. All of them appear in the budgets of the successor states for a decade, and a reorganisation Act that handles them badly purchases a short political victory at the price of a long fiscal quarrel.

What a reorganisation Act must do: the ten standard heads

A reorganisation Act is best understood as a machine for converting one legal order into two or more without a gap. The political decision it carries could be written on a page. The statute that carries it cannot, because on the morning after the division everything must still work: courts must know which cases are theirs, treasuries which debts they owe, officers which government they serve, and citizens which law governs the act they performed the day before. Across the Acts of 1956, 1960, 1966, 1971, 2000, 2014, and 2019, the solution has converged on a standard set of heads, so stable that the Andhra Pradesh Act of 2014 and the Madhya Pradesh Act of 2000, passed fourteen years apart by different governments for different regions, are recognisably the same instrument with different schedules. The table below states the heads, and the prose that follows takes the contested ones in turn.

The convergence is itself worth a moment’s attention, because it was not imposed by any drafting manual. The Act of 1956 was the first full working of the problem, assembled under pressure by draftsmen solving questions nobody in India had solved before: how to divide a public debt that had never been divided, how to allot a civil service that had never been split, how to keep a million pending files moving while the courts that held them changed their names. Its solutions became the template because they worked tolerably and because the alternative, inventing a new machinery for each division, promised fresh litigation on every clause. Later draftsmen copied the structure the way engineers copy a bridge design that has carried its load, varying the schedules to the case and keeping the spans. A reader comparing the Acts across seventy years is therefore reading a tradition as much as a series of statutes, and the tradition’s conservatism is a feature with a rationale: in transitional law, the known imperfection is usually worth more than the untested improvement, because the costs of the transition fall on people who did not choose it.

Head of the Act	What it decides	Who is affected	A dispute that has arisen under it
Appointed day	The single date from which the new units exist and every other provision is reckoned	Every person and institution in the affected territory	Fights over whether a liability, appointment, or transaction falls before or after the line, as in the reckoning of balances between Andhra Pradesh and Telangana from 2 June 2014
Territories	The districts and areas composing each successor unit, usually by schedule	Residents of every border district	The allocation of Belgaum to Mysore in 1956 produced the Maharashtra and Karnataka border dispute, the Mahajan Commission, and an original suit in the Supreme Court
Parliamentary representation	The division of the parent state’s seats in the Council of States and the House of the People, amending the Fourth Schedule	The successor states and their sitting members	The allotment of sitting Council of States members between Andhra Pradesh and Telangana in 2014 had to be settled by a draw of lots
Assembly and delimitation	The strength of each successor assembly, the allotment of sitting members, and the delimitation of constituencies	Legislators and electors in both units	The delimitation of the Jammu and Kashmir assembly under the 2019 Act, concluded by the order of 5 May 2022, was contested by the region’s parties on its allocation between divisions
High Court	Whether each unit gets its own court, or one court serves both, and what happens to its judges	Litigants, the bar, and the judiciary of both units	The common High Court at Hyderabad served two states for over four years before separate courts were constituted on 1 January 2019, after litigation over the delay
Assets and liabilities	The division of public debt, financial assets, land, buildings, and institutions between the successors	The treasuries and public institutions of both units	The division of the institutions listed in the Ninth and Tenth Schedules to the 2014 Act remained contested between the successor states for years
Services	The allocation of officers and employees, their cadre, seniority, and conditions of service	Every public employee of the divided state	Employee allocations between Andhra Pradesh and Telangana generated sustained litigation over options, seniority, and local status
Continuance and adaptation of laws	Which laws continue in the successor territories, and who may adapt them to the new map	Every person governed by the divided state’s laws	The Fifth Schedule to the 2019 Act applied 106 central laws to the new Union territories and repealed 153 state laws, a substitution litigated and debated as part of the larger challenge
Pending proceedings	The forum in which cases, appeals, and proceedings pending on the appointed day continue	Parties to every pending case in the territory	Proceedings before the common High Court at Hyderabad had to be allocated between the two successor courts when the courts separated in 2019
Removal of difficulties	A time-limited power for the executive to issue orders resolving problems the Act did not foresee	Anyone affected by a transitional gap	Removal of difficulties and adaptation orders under the 2019 Act, beginning with the order of 30 October 2019, were attacked as executive legislation beyond the clause’s purpose

The appointed day is the hinge of the whole instrument. It is a date fixed by notification, not necessarily the date of assent or of publication, and the Act is drafted backwards from it: the territories described are the territories as they will stand on that day, the balances divided are the balances as they will stand on that day, and the officers allocated are allocated with effect from that day. The choice of date is therefore never a clerical matter. Between assent and the appointed day there is an interval of preparation in which the successor governments exist in embryo, and the length of that interval is itself a political decision. The 2014 Act allowed three months, from assent on 1 March to the appointed day on 2 June. The 2019 Act allowed a similar span, from 9 August to 31 October. Every dispute about whether a liability belongs to the old state or a successor is, in form, a dispute about which side of the appointed day it falls on, and such disputes are the daily fare of the finance departments of divided states long after the celebrations end.

Why does almost everything in a reorganisation turn on the appointed day?

Because the appointed day is the hinge on which every legal consequence of the division swings. Territory, representation, courts, services, assets, debts, and laws all transfer by reference to that single date, so a draftsman who fixes it precisely has answered in advance the question every later dispute asks first: which side of the line?

Because the Act divides a going concern, not a blank sheet. On the appointed day the old state ceases to exist in its previous form, and every asset, debt, officer, case, and law must already have an owner, a forum, and a text. The date converts a political decision into thousands of legal consequences at a single stroke, which is why its choice and its reckoning generate so much of the litigation.

The territorial head looks the simplest and lasts the longest. A reorganisation Act describes the successor units by listing districts and areas, frequently in a schedule, and a district is a large and internally varied thing. Border districts almost always contain populations whose language, markets, and loyalties point across the new line, and where the Act draws the line through a mixed district it creates a grievance with an indefinite life. The standing example is Belgaum, allocated by the 1956 settlement to the state that became Karnataka. Maharashtra’s claim, pressed from 1960 onward on grounds of linguistic majority and contiguity, produced the Mahajan Commission, constituted on 25 October 1966 under the former Chief Justice Mehr Chand Mahajan, whose report recommended that Belgaum city remain with Karnataka while exchanges of villages took place on both sides. Karnataka accepted the report’s core. Maharashtra rejected it outright, and in 2004 carried the claim to the Supreme Court in an original suit under Article 131, the constitutional route for disputes between states. The suit’s existence, decades after the Act, is the point: a territorial schedule is a legal instrument, but the disputes it settles on paper continue in politics until both sides accept the settlement as final, and the Act cannot compel that acceptance.

The representation heads show the Act doing constitutional work by ordinary legislation. Article 4 authorises the reorganisation law itself to amend the Fourth Schedule, which allocates seats in the Council of States among the states, and to settle representation in the House of the People and the successor assemblies. The division follows the territory. When Madhya Pradesh was divided in 2000, its sixteen seats in the Council of States became eleven for Madhya Pradesh and five for Chhattisgarh, its forty seats in the House of the People became twenty-nine and eleven, and its assembly of 320 members became assemblies of 230 and 90. Sitting members must also be placed, and the Acts allot them by rule: a member whose constituency falls in the new state is deemed elected for it. Where the members represent a whole state rather than a constituency, as in the Council of States, the allotment can require an element of chance, and in 2014 the sitting members from undivided Andhra Pradesh were allotted between the successor states, eleven seats to Andhra Pradesh and seven to Telangana, by a draw of lots conducted for the purpose. The constituencies themselves are then redrawn by delimitation, an exercise whose governing statutes and constitutional freezes are treated in the article on the Delimitation Acts and the redrawing of seats, and which in Jammu and Kashmir after 2019 was carried out by a commission constituted under the 2019 Act itself, chaired by Justice Ranjana Prakash Desai, whose final order of 5 May 2022 fixed ninety assembly seats, forty-three in the Jammu division and forty-seven in the Kashmir division, with nine seats reserved for the Scheduled Tribes and seven for the Scheduled Castes, an allocation the region’s parties contested from opposing directions. The assembly head also exposes a small design constraint that every creation of a small state must negotiate. Article 170 fixes the size of a legislative assembly between a maximum of five hundred and a minimum of sixty members, a floor that several of the Union’s smallest states cannot sensibly meet, and the map’s smallest units sit below it by grace of special provision or of the terms on which they were created: Goa’s assembly has forty members, Mizoram’s forty, and Sikkim’s thirty-two. A reorganisation that creates a small state therefore reaches, once again, for the companion instruments this article has tracked throughout, the special provision and the schedule, because the standard template does not fit the standard’s own smallest products.

The High Court head offers the draftsman three models, and the choice among them has repeatedly mattered. The first is a separate court for each successor, the course taken in 2000, when each of the three new states received its own High Court seated within its territory. The second is a common High Court, which Article 231 of the Constitution expressly permits Parliament to establish for two or more states: the Punjab and Haryana High Court at Chandigarh is the enduring example, and the High Court of Judicature at Hyderabad served Andhra Pradesh and Telangana in common from 2014, under section 30 of the 2014 Act, until the President’s orders of 26 December 2018 constituted a separate High Court for Andhra Pradesh with effect from 1 January 2019, leaving the Hyderabad court to Telangana. The third is continuation, used in 2019, when the existing High Court of Jammu and Kashmir simply continued as the common court for both new Union territories. The interval of common jurisdiction is not dead time. Judges must be allocated, records divided, and the question of when the promised separate court will arrive has itself been litigated, as it was by the Andhra Pradesh bar in the years before the 2019 separation.

Assets, liabilities, and services are the heads under which reorganisation is experienced by the state itself, and they share a common structure. Financial assets and public debt are apportioned between the successors, ordinarily in the ratio of their populations, while physical assets generally follow their location. Institutions that served the whole of the old state, its corporations, boards, universities, and training establishments, cannot follow location so easily, because many of them sit in the capital that one successor keeps; the 2014 Act therefore listed them in its Ninth and Tenth Schedules and provided for their division or shared use, and the working out of those schedules between Andhra Pradesh and Telangana remained incomplete and contested for years, with each state accusing the other of withholding what the Act assigned. Services follow the same pattern with human stakes. The Acts allocate the officers of the All India Services between the cadres of the successors and provide machinery, through committees, options, and final orders by the Union government, for allocating state service employees, protecting their pay and conditions in the transfer. An officer’s allocation decides where a career will be spent and where seniority will run, and the litigation these decisions generate, over options exercised, local status claimed, and seniority lost, is the longest tail of any reorganisation. A reader who wants the human meaning of the word successor state will find it in the service lists.

The services head divides into two distinct operations that the Acts handle differently. The All India Services, the Indian Administrative Service, the Indian Police Service, and the Indian Forest Service, are organised in state cadres, and a division splits the cadre itself. The Union government, which controls the cadres, allocates the serving officers between the two successor cadres, balancing the officers’ preferences against the successors’ requirements and the need to keep seniority intelligible within each new list. The operation is technical and its outcomes are personal in the extreme, since an officer’s cadre decides the state in which a career will be spent, and the allocations after both 2000 and 2014 were followed by representations and litigation from officers who drew the side of the line they had not chosen. State service employees, the far larger body, are allocated under the Act’s own machinery, which characteristically gives the employee an option where the scheme permits, processes the options through an advisory committee, and leaves the final allocation to be made by or with the approval of the Union government, with a governing principle that no employee’s pay and conditions shall be worsened by the transfer. The two operations share a feature the reader should note: in services, unlike in territory, the Act deals with named individuals, and every general rule it states is somebody’s posting, promotion, and pension. It is the head under which the largest number of individual grievances arise, and the one whose disputes are least visible in the public record, being scattered across the service tribunals and High Courts of both successors for years after the division is otherwise complete.

The laws head conceals the largest single act of legal engineering in the instrument. The default rule across the Acts is continuity: every law in force in the old state immediately before the appointed day continues in force in each successor territory until the competent legislature alters it, and the Acts equip the successor governments with a time-limited power to adapt those laws, by order, to the new map, substituting the new state’s name and authorities for the old. Continuity is what makes a division administrable, since the alternative, a legal vacuum in one successor, is unthinkable; but continuity also means that for years after a division the statute book of each successor is largely the old state’s book with a new cover, and the two books diverge only as the two legislatures amend them at different speeds and in different directions. The 2019 Act is the great exception, because the territory it reorganised had lived under a distinct constitutional regime. Its Fifth Schedule applied 106 central laws to the new Union territories, repealed 153 of the state’s laws, and continued the remainder, while section 96 gave the Central Government one year to adapt laws by order for facilitating their application. Where the standard head preserves, the 2019 Act substituted, and the scale of that substitution was among the grounds on which the whole exercise was debated and challenged.

Pending proceedings receive a standard answer with sharp edges. Suits, appeals, and other proceedings pending in the courts of the old state on the appointed day continue in the corresponding courts of the successor in whose territory the cause of action or the subject matter lies, and proceedings before the old state’s High Court are distributed when the courts divide. The rule is mechanical until it is not: a transaction begun in one successor’s territory and completed in another’s, a contract with performance on both sides of the line, or an offence spanning the appointed day can put the forum itself in issue, and the transitional chapters of the Acts are written precisely to give courts a rule for those cases. The removal of difficulties clause closes the instrument. It empowers the executive, for a limited period stated in the Act, to issue orders not inconsistent with the Act’s provisions for removing any difficulty that arises in giving effect to it, with the orders laid before the legislature. The clause is an admission that no draftsman can foresee the whole of a division, and it is correspondingly open to abuse in the eyes of its critics, who read orders under it as executive amendment of a parliamentary settlement. The Jammu and Kashmir Reorganisation (Removal of Difficulties) Order, 2019, issued on 30 October 2019 on the eve of the appointed day, and the adaptation orders that followed under the 2019 Act, drew exactly that objection, and the objection states a permanent tension in the design: a reorganisation Act must delegate to be workable, and everything it delegates is a small transfer of the map-drawing power from Parliament to the government of the day.

The structural logic: where the power overlaps and where it stops

Read across the field, three structural features organise everything else. The first is the overlap between reorganisation and constitutional amendment. Most reorganisations travel by ordinary law alone, but the largest of them have needed an amendment as a companion, not to authorise the redrawing, which Article 3 already authorises, but to clear the constitutional furniture out of its path. The 1956 settlement required the Seventh Amendment because the Constitution’s original classification of states into Parts A, B, C, and D had to be abolished and replaced by a simple division between states and Union territories. Sikkim’s entry required amendments because its terms were entrenched in the text. The creation of legislative councils, the special provisions collected in the Article 371 series for particular states and regions, and the reservation arrangements that follow territory, all sit at this junction: the map moves by simple majority, but the constitutional text that describes the map’s special cases moves only by amendment, and a complete account of any large reorganisation must track both instruments. The 2014 Act illustrates the junction neatly, since the special provisions for the region in Article 371D had to be carried across both successor states by presidential order even though the division itself needed no amendment.

The second feature is the asymmetry the design tolerates and even creates. The states of the Indian Union are not uniform units with identical powers and histories. Some carry special provisions negotiated at accession or enacted later; some share a High Court, a capital, or a Governor’s special responsibilities; some are governed in their tribal areas by the Fifth and Sixth Schedules, whose arrangements a reorganisation must expressly save or expressly disturb. Reorganisation Acts therefore do more than draw lines. They decide which of the old unit’s asymmetries each successor inherits, and the decisions are among the most contested in the instrument, because a special provision is usually a settlement of somebody’s grievance, and reopening it reopens the grievance.

The third feature is a gap, and it is the one that generates the longest disputes. A reorganisation Act settles the division of the state as a legal person: its territory, seats, courts, debt, officers, and laws. It does not, and within its own terms cannot, settle the relations that the successor states must then conduct with each other as neighbours. The waters of an inter-state river do not divide because a schedule says the states have divided. The sharing arrangements fixed or assumed at the division, as the Ravi and Beas waters were apportioned in the settlement that accompanied the 1966 reorganisation of Punjab, become the subject matter of agreements, tribunals, and litigation between the successors for decades afterwards, of which the Sutlej-Yamuna Link canal dispute between Punjab and Haryana is the standing example. The same holds for power projects, for the assets of boards that operated across the new line, and for the employees of institutions that both states claim. The Act ends the old state. It cannot end the interdependence that the old state’s unity had made invisible, and a reader who understands that distinction understands why reorganisation is a beginning in administrative law even when it is an ending in politics.

The asymmetry point deserves one further turn, because the Constitution’s special provisions for particular states and regions, collected in the Article 371 series, are the layer of the federal design that reorganisation most often has to renegotiate. Article 371A protects Naga customary law and land ownership against parliamentary legislation unless the Nagaland Assembly resolves otherwise. Article 371D, inserted for Andhra Pradesh in 1973, built a scheme of equitable opportunities in public employment and education across that state’s regions, and its zonal arrangements were among the grievances and the safeguards that the 2014 division had to carry into both successor states by presidential adaptation. Article 371J, inserted in 2012, does similar work for the Hyderabad-Karnataka region within Karnataka, a region whose separateness is the residue of the 1956 settlement itself. Each of these provisions is a scar left by an earlier failure of the map to fit the country, constitutionalised so that the grievance need not be reopened. A reorganisation that touches any of them must decide whether the scar tissue transfers, divides, or dissolves, and the decision is a constitutional judgment wearing the dress of a schedule. The 2019 reorganisation is again the extreme case: the special provision for Jammu and Kashmir stood outside the 371 series in Article 370, and the reorganisation did not adapt it but accompanied its abrogation, so that the successor territories entered the Union’s ordinary arrangements entire. Whether an asymmetry is a settlement to be preserved or an anomaly to be ended is the kind of question the map-drawing power forces and cannot answer by itself, and it recurs wherever the field’s history has left a region with rights the standard pattern does not give.

It is worth pausing on one institution the 1956 Act built precisely to manage that interdependence. Part III of the States Reorganisation Act established five Zonal Councils, statutory bodies chaired by the Union Home Minister and bringing together the chief ministers of the states in each zone, to discuss matters of common interest, from boundary questions to economic planning. The councils are advisory and their record is uneven, but their presence in the founding statute is a reminder that the draftsmen of 1956 understood the point this section makes: redrawing the units creates a permanent need for machinery between them, and the machinery has to be legislated for in the same breath as the lines.

Reorganisation and the arithmetic of the Council of States

One consequence of the map is easy to overlook because it accrues to neither successor. The Council of States is composed by the Fourth Schedule’s allocation among the states, and every reorganisation rewrites that allocation, dividing the parent state’s seats between the successors as the 2000 and 2014 examples showed. The total size of the Council barely moves, since the seats divided are the seats that exist. What changes is the distribution of voice. A state of a given population speaks in the Council with the seats the Schedule gives it, and when it divides, the two successors together hold the same seats between them, but each speaks separately, with its own delegation, its own party arithmetic, and its own occasions to be courted by a Union government assembling a majority. Over the whole period of reorganisation, the steady multiplication of states, from fourteen in 1956 to twenty-eight after the conversion of 2019, has multiplied the number of delegations without multiplying the seats in proportion to population, since new states are carved from old ones rather than added to the Union’s territory. The result is a second chamber whose composition has drifted, division by division, toward the representation of units and away from the representation of population, a drift nobody designed in a single step and every step of which was taken by the same ordinary law. Students of the design regard this as one of its quiet structural consequences: the power that redraws the map also, slowly, reweights the federation’s own upper house, and it does so as a side effect that the debates on each Bill rarely mention.

The House of the People is insulated from the same drift by the constitutional freeze on the readjustment of seats, under which the allocation of Lok Sabha seats among the states stands fixed on the basis of the 1971 census until the figures of the first census taken after the year 2026 are published. A reorganisation therefore divides the parent state’s existing Lok Sabha seats between the successors, as the Madhya Pradesh division divided forty into twenty-nine and eleven, rather than reopening the national allocation. The insulation is temporary in principle and long-lived in practice, and its eventual expiry will present the Union with a question of the same family as reorganisation itself: how the people’s house is to be shared among states whose populations have grown at very different rates. That question belongs to the delimitation articles of this series, but its kinship with this one should be registered. Both ask how a union holds together units of unequal size under a single legislature, and the Constitution answers the two questions with opposite instruments, the map by simple majority and the seats by freeze.

Shared institutions: the halfway architecture

A division that severed everything at the appointed day would be unworkable, and the design therefore keeps a stock of shared institutions that hold the successors together for a time, or indefinitely. The Constitution itself supplies several. The proviso to Article 153 permits the same person to be appointed Governor of two or more states, a device used after the 2014 division when one Governor served both Andhra Pradesh and Telangana through the transition, and used in the arrangements for Punjab and Haryana, where the Governor of Punjab serves also as Administrator of Chandigarh. Article 231 permits a common High Court, and the reorganisation Acts have used common courts, a common capital, and common service cadres as transitional architecture with varying lifespans. Hyderabad was the common capital of the 2014 successors for ten years by the Act’s own terms, a period chosen to give the residuary state time to build a capital while sparing it the shock of instant exile from its own metropolis. Chandigarh’s shared status, by contrast, was framed in 1966 as temporary and has outlasted most of the politicians who framed it, because the transfer promised by the Rajiv-Longowal Accord of 1985 was never carried out and no subsequent settlement has commanded both states’ acceptance. The lesson generalises beyond any single case. In this field, transitional arrangements should be read as permanent until the instrument that ends them is identified, because the politics that made them necessary at the appointed day tend to persist, and a shared institution, once built, acquires constituencies of its own.

What reorganisation does not disturb

The widest power in the field is also, in one respect, carefully bounded, and the boundary matters to the ordinary reader more than the constitutional theory does. A reorganisation changes the public law map. It does not rewrite private rights. Land owned the day before the appointed day is owned the day after, under the same title, in whichever successor the land lies; the land records travel with the territory. Contracts between private parties are untouched. The state’s own contracts, its works agreements, concessions, and borrowings, are dealt with by the Acts expressly, which allocate the rights and liabilities under them between the successors, ordinarily following the territory the contract concerns, so that a contractor building a road in the new state finds the new state on the other side of the agreement without any act of his own. Citizenship is unaffected, being a Union subject that knows no state-level variation in status, though the administrative incidents of citizenship, the domicile certificates, local reservations in education and employment, and caste and tribe lists that run by state, are all disturbed in practice and must be re-issued, adapted, or grandfathered by the Acts and the orders under them. The Scheduled Castes and Scheduled Tribes lists, which are state-specific in their operation, are a standard instance: a community recognised in the old state may find its recognition in a successor governed by the list as the reorganisation law and subsequent presidential orders adapt it, and the litigation that follows such adaptations is a quiet measure of how much of ordinary life a change in the map reaches. The point of the boundary is reassurance with a warning inside it. Nothing private is confiscated or annulled by a division. Almost everything administrative must be re-papered, and the re-papering is the work of years.

A newer federal body repeats the pattern in a different register. The Goods and Services Tax Council, created by the One Hundred and First Amendment in 2016, decides by weighted voting in which the Union carries one third of the weight and the states together carry two thirds, each state counting as a voice in the state bloc. Every new state therefore adds a voice to the bloc and marginally reweights every other state’s share of it, so that the arithmetic of indirect taxation in India shifts, slightly and permanently, with each division of a state. No debate on a reorganisation Bill has ever turned on the point. It stands here as a further exhibit of the article’s central observation: in a federation built this way, redrawing the map is never only about the territory redrawn, because the federation’s own decision-making bodies are composed of the units, and to change the units is to change, in small compounding ways, every decision those bodies will ever take.

The consent question: the strongest case on each side

The legal position is not in doubt, and this article has stated it without qualification: no consent is required, the reference is a consultation, and a reorganisation law is ordinary legislation. The political and constitutional argument about whether the position should be so is a different matter, and it deserves to be stated at full strength on both sides, because it is the argument that every future reorganisation will rerun.

It should be recorded that the design was not adopted without the alternative being put. In the Constituent Assembly’s debates on the draft article that became Article 3, members moved amendments that would have required the consent, or the prior concurrence, of the affected state’s legislature, and the Assembly, after debate, did not adopt them. The consultation formula in the proviso is what the Assembly chose instead, deliberately, against a consent formula that was before it in terms. Later critics who describe the absence of consent as an oversight misread the record. It is a decision, taken with the alternative in view, and the argument about it is an argument with the framers’ reasoning, not with their drafting.

The case for the design begins with the character of the units. The states of India were not sovereign parties to a compact. They were created, in their inherited form, by conquest, annexation, and administrative convenience under a colonial power, and then by integration agreements negotiated in the extraordinary circumstances of 1947 and 1948. A constitution that required their consent to be redrawn would have treated the accidents of that process as permanent entitlements. The framers, legislating for a country whose map they knew to be provisional, deliberately withheld the veto, and Ambedkar’s defence of that choice in the Constituent Assembly remains its classic statement: the Union is a single integral whole, and its division into states is an administrative arrangement within the whole, not a treaty among its parts.

The case continues with the position of minorities within states. Every large state contains regions whose language, history, or economy sets them apart from the state’s majority, and those regions are, by definition, permanent minorities in the state legislature whose consent a consent rule would require. To give the legislature of Andhra Pradesh a veto over Telangana’s separation was to give the majority region of that state a permanent power to hold the minority region within a political unit it sought to leave. The defenders of the design ask what answer federalism gives to such a region if the door at the state level is locked: the only remaining doors are agitation and the Union. Article 3 is the constitutional form of that second door, and its defenders point to the record of accommodation it made possible, from Andhra in 1953 to the three creations of 2000, as evidence that the absence of a veto has more often released pressure than overridden legitimate self-government. On this view, the linguistic reorganisation itself is the proof: a settlement widely predicted to fragment the country is credited, by historians of the period, with the opposite effect, because it gave language a constitutional home inside the Union instead of leaving it as a grievance against the Union.

The case against the design begins where the case for it ends: with the meaning of the word federal. A federation in which one level of government can abolish, divide, or downgrade the other level by ordinary legislation is, on the classical understanding, federal in a limited sense only, and Wheare’s description of India as quasi-federal was aimed at exactly this asymmetry. The consultation that the proviso requires is, on this view, a formality dressed as a safeguard. The state legislature is summoned to express views that the deciding body is entitled to ignore, within a period the deciding body’s own head of state fixes, on a Bill the deciding body’s government alone can introduce. Critics of the design ask what work the word consultation is doing in such a scheme, and their strongest exhibits are the two most prominent reorganisations of the contested mode. In 2014, the legislature of the affected state debated the Bill and resolved against it, and the division proceeded on schedule. In 2019, the affected state had no functioning legislature at all, being under President’s rule, and Parliament supplied the state’s voice itself before converting the state into two Union territories. Whatever the merits of either decision, the critics’ structural point stands apart from them: in the two hardest cases, the consultation requirement constrained nothing, and a safeguard that constrains nothing in the hardest cases is not a safeguard.

The critics also press a point about incentives. Because reorganisation requires only a parliamentary majority, it is available as an instrument of ordinary politics. The same power that accommodates a genuine regional movement can reconfigure a state whose government belongs to a rival party, adjust the arithmetic of the Council of States, or create units small enough to be fiscally dependent on the Union that created them. The defenders reply that the political costs of an unwanted reorganisation are themselves the check, since a Union government that divides a state against its people’s wishes must answer for the consequences at the next election, and that the history of the power shows it used sparingly and, in most instances, in response to sustained movements rather than convenience. Both propositions can be true at once, and their tension is the honest centre of the debate.

Reform proposals cluster at the modest end, because the immodest end, a consent amendment, would require the very parliamentary majorities the proposal distrusts. The recurring suggestions are to make the consultation real without making it a veto: reference of proposals to the Inter-State Council, the body Article 263 authorises for exactly this class of question; a standing commission on state formation so that claims are examined against published criteria rather than taken up in the heat of a movement; and longer, fixed periods for the state legislature’s views, so that the reference cannot be outwaited by design. The Sarkaria Commission on Centre-State Relations, which reported in 1988 after the most extensive official examination of the federal system since the Constitution, considered this article directly and recommended that the Union exercise the power sparingly and in consultation with the state concerned, while stopping short of proposing that consent be made a condition. The Commission on Centre-State Relations chaired by Justice Madan Mohan Punchhi, which reported in 2010, recommended in the same spirit that the Union consult the states through the Inter-State Council before legislating on matters that concern them. None of these proposals has been enacted, and the design therefore stands as the framers left it. What is settled is the law. What is contested on the facts is whether particular consultations have been genuine. What is contested on values is whether a union of this kind should be able to redraw its own map, and on that question this article records the disagreement rather than pretending the text answers it.

The map comes before the Lists

There is a reason this cluster sits where it does in the architecture of the Constitution, ahead of the distribution of legislative power. Articles 2 and 3 come in Part I, before the citizenship provisions have finished and long before the Seventh Schedule divides subjects between the Union and the states. The sequence is logical, not accidental. The division of powers presupposes the units among whom power is divided. Before anyone can ask what a state may legislate on, someone must have decided that the state exists, with these boundaries and this legislature. Article 3 is that prior decision, and every change to the map silently rewrites the reach of every entry in the three Lists for the people who wake up in a different state from the one they went to sleep in. The reader who wants the Lists themselves, their contents, their overlaps, and the doctrine that resolves conflicts between them, should go to the article that compares the Union, State and Concurrent Lists; the point for this guide is the priority. Reorganisation does not merely move lines on a map. It moves every subject in the State List and the Concurrent List, for millions of people, from one legislature’s hands to another’s.

Status is the sharpest form of this priority. A state legislature commands the whole of the State List. The legislature of a Union territory with a legislature, of which Delhi and Puducherry were the standing examples before 2019 and Jammu and Kashmir became the third, legislates on a narrower grant, with subjects such as public order and police reserved to the Union’s representative. The conversion of 2019 therefore did more than rename the unit on whose territory it operated. It changed which legislature could make law on the subjects that touch daily life most closely, and it did so by the same ordinary law that redrew the map. The map and the mandate are one decision, and Article 3 takes both together.

The demands that recur, and how to read them

The power’s existence guarantees its politics. Because a new state can be created by ordinary law, no statehood demand is ever constitutionally hopeless, and the demands therefore recur across generations. Vidarbha’s claim is the oldest of the standing ones: the States Reorganisation Commission itself recommended a separate Vidarbha state, and the Union government of the day chose the bilingual Bombay experiment instead, leaving a recommendation on the record that advocates in the region have cited ever since. In the north, Bundelkhand’s demand crosses the boundary between Uttar Pradesh and Madhya Pradesh, and Purvanchal’s claim would divide Uttar Pradesh again after 2000. Within West Bengal, the Gorkhaland movement sought a state for the Darjeeling hills and obtained instead a territorial administration, the standard half-way house of this field, in which autonomy is conceded and statehood withheld. In Assam, the Bodo accords built a territorial region under the Sixth Schedule through successive settlements. Saurashtra, Mithilanchal, Koshal, and other regions carry demands of varying intensity, taken up and set down with electoral cycles. This guide takes no position on any of them. It observes only that each would travel the same legal road, a government Bill on the President’s recommendation, a reference to the affected legislature, and a parliamentary majority, and that the presence or absence of a movement’s strength in Parliament, rather than any legal criterion, is what has historically separated the demands that became states from the demands that remain resolutions.

For the researcher or the journalist following one of these demands over years, the record is scattered by design: commission reports, assembly resolutions on a reference, the schedules of a Bill, orders under an Act, and judgments years later are the documents that matter, and they accumulate slowly. Keeping that file in order, so that the resolution of one year can be set against the assurance of another, is the unglamorous work on which accurate writing about reorganisation depends, and how journalists use VaultBook to protect sources describes a way of holding such a file privately while it grows. One caution belongs in any account of this subject, and it is the caution this whole series observes: the general law stated here is legal information, not advice. A person whose land record, service seniority, pension, or pending proceeding is caught by a particular division faces consequences that turn on that Act’s schedules and transitional orders, and should take advice on the individual facts, because those provisions are unforgiving of delay.

The small states question

Running beneath the particular demands is a general argument about size, and a thematic guide should state it in the abstract because it will outlast every particular demand. The advocates of smaller states argue from the logic of administration and representation together. A state of a hundred million people, as Uttar Pradesh became, contains more citizens than most nations, and its government sits at a distance from most of them that no administrative reform can cure; its chief minister cannot know its districts, its legislature cannot represent its regions in any proportion that gives the regions weight, and its politics is dominated by the regions that supply its majorities. Division brings the capital closer, gives the neglected region a legislature in which it is the majority, and lets policy be made for its economy rather than for the average of a giant. The advocates of the 2000 creations point, in support, to the growth and governance records the three new states compiled in their first decades, and to the visibility of regions, the Chhattisgarh plains, the Jharkhand plateau, the Uttarakhand hills, that had been administrative peripheries.

The critics of smallness answer on three grounds. The first is fiscal: a state must carry the fixed apparatus of statehood, a governor, a High Court, a secretariat, a public service commission, and the overheads fall on a smaller revenue base, leaving many small states dependent on Union transfers for the larger part of their spending and correspondingly exposed to the Union’s priorities. The second is administrative: the All India Services are thin at the senior levels, and multiplying states multiplies the demand for experienced officers faster than the supply, so that the smallest states may be governed by the least experienced cadres. The third is systemic: every new state creates new inter-state relations, over water, power, boundaries, and shared institutions, and the machinery for managing those relations, as this article has shown, is slower than the machinery for creating the states. The critics also note what the advocates’ evidence omits, that the decades in which the 2000 states recorded their growth were decades of growth across nearly all of India, and that the new states began with endowments, mineral wealth in two cases, that flatter the comparison.

The honest position is that the Constitution does not decide this argument and no commission has settled it empirically, because the counterfactual, the undivided state that might have been, is never available for inspection. What the record supports is narrower: size alone predicts little, the quality of the settlement’s schedules predicts much, and the states created with their fiscal and institutional homework done have fared visibly better in their first years than those created in haste. That is a conclusion about drafting, not about geography, and it is the conclusion this whole guide has been building toward.

The second commission question, and the premium on agitation

Every generation of this debate produces the same proposal, that the Union should appoint a second States Reorganisation Commission, a standing or periodic body that would examine all pending demands against published criteria and take the question out of the politics of the moment. The proposal’s attractions are real. A commission converts a contest of strength into an inquiry into merits. It can compare claims that compete for the same territory, hear the parent state’s case at leisure rather than in the crisis of a movement, and apply one set of criteria to Vidarbha and Bundelkhand and Gorkhaland alike. Its defects are equally real, and they explain the Union’s consistent refusal to appoint one. A commission announced is a starting gun: every dormant claim in the country would be pressed before it, in the knowledge that inclusion in its report is the strongest currency a demand can hold, and the experience of 1953 to 1956, when one commission’s appointment multiplied the claims it was appointed to settle, is the standing warning. A commission also decides nothing; its report returns to the same parliamentary majority for enactment, and a government that dislikes its conclusions shelves them, as inconvenient passages of the first Commission’s report were rearranged in 1956. The case-by-case method the Union has preferred has its own pathology, which the critics of the method name precisely: it rewards agitation. On the record of this field, states have followed movements, fasts, and electoral pressure far more reliably than they have followed memoranda, and a process that responds to pressure teaches every region the same lesson about how states are won. The defenders of the case-by-case method answer that statehood is a political act and cannot be technocratised without falsifying it, and that a government answerable to Parliament is a better judge of the country’s cohesion than a body answerable to no one. The argument is unresolved, and it will be rerun, in these terms, at the next demand that gathers force.

Names on the record: what the First Schedule holds

The First Schedule is the Union’s register of itself, and its entries are the legal names of the units, not descriptions of them. A state is, in law, what the Schedule says it is, with the territories the Schedule specifies, and the reorganisation law’s amendment of the Schedule is the moment the new map becomes the Constitution’s own statement of the country. This is why the lightest exercises of the power, the name changes, are instructive out of proportion to their size. When Orissa became Odisha in 2011, the change required not only the alteration of the state’s entry but a companion amendment of the Constitution’s Eighth Schedule, where the language’s name stood as Oriya and became Odia, because a name in this system is not a label but a text that appears in several instruments at once and must be changed in all of them to be changed at all. Below the level of the Schedule, the Acts are careful to preserve the ordinary machinery of naming: the States Reorganisation Act itself saved the power of state governments to alter the name, extent, and boundaries of any district or division within the state after the appointed day, a provision that keeps the daily cartography of administration in state hands while the constitutional cartography stays with Parliament. The distinction is the field in miniature. Parliament decides what the units are. The units then govern everything inside their lines, including the lines of their own districts, until Parliament decides again.

Reading a reorganisation Act: a short method

For the researcher who must use one of these statutes rather than admire it, the Acts reward a particular order of reading. Begin with the appointed day notification, because every date in the Act is a shadow of it. Read the territorial schedule next, and read it against a district map, since the schedule’s lists of districts and taluks are the operative definition of the new state and prevail over every description in debate. Then take the representation provisions and the two constitutional schedules the Act amends, which fix the successor’s place in Parliament and are the provisions most often needed by a reader answering a factual question. The financial chapters, on apportionment, should be read with the population ratio in hand, since most of their figures are that ratio applied to different balances. The services chapters repay attention to their committee and option machinery rather than their lists, because the lists change by order while the machinery decides whose list a disputed officer lands on. The laws chapter and the adaptation orders made under it are where the statute book of the successor is actually written, and they should be checked before any statement about the law in force in a successor state is made. Finally, the removal of difficulties orders should be collected and read as a supplement to the Act itself, because in the first years of a successor state they are frequently where the operative rule lives. An Act read in this order yields its answers quickly. An Act read from the preamble forward, as literature, conceals them, which is perhaps why so much public writing about reorganisation describes the politics fluently and the instrument hardly at all.

Verdict

The series to which this article belongs has repeatedly found that a provision’s significance lies in what it does not require. Article 3 is the purest instance in the Constitution. It does not require the consent of the state divided, the agreement of the people moved, a special majority in the House that divides them, or the ratification of any other state. It requires a recommendation, a reference, and an ordinary law, and Article 4 then declares that the law is not even an amendment. What that spare text has produced is the entire modern map: fourteen states and six territories in 1956, the linguistic settlement completed in the 1960s, the north-east rebuilt in the 1970s, three states in a month in 2000, a bifurcation over the parent assembly’s rejection in 2014, and a conversion without precedent in 2019, whose widest question the Supreme Court has expressly left open. The map of India is often described as ancient and given. In law it is neither. It is a schedule, maintained by ordinary legislation, and the articles that follow this one take up, statute by statute, what maintaining it has involved. The reader who keeps three questions in hand through the cluster will not go wrong: who decided, under which head of which Act the consequences were settled, and what the settlement left for the successors to fight about afterwards. Those questions, applied to each statute in turn, convert a subject usually reported as sentiment into the legal history it actually is, and they are the questions this guide has tried to make habitual.

A new state is created by a law of Parliament under Article 3 of the Constitution. The process begins with a decision of the Union government, because a Bill for the purpose can be introduced in either House only on the recommendation of the President, which in practice means as a government measure. If the proposal affects the area, boundaries, or name of an existing state, the President first refers the Bill to that state’s legislature to express its views within a specified period. Parliament then debates and passes the Bill by a simple majority, the President assents, and the new state comes into existence on the appointed day notified under the Act, with the Act itself settling territories, representation, assets, services, and laws.

Q: Does a state have to agree to its own reorganisation?

No. The Constitution requires consultation, not consent. The proviso to Article 3 obliges the President to refer a reorganisation Bill to the legislature of an affected state so that it may express its views within the period specified, and the President may extend that period. The views expressed do not bind Parliament, which may enact the Bill against the state legislature’s stated opposition, after the period expires without a reply, or with amendments the legislature never saw, provided any amendment remains germane to the original proposal, as the Supreme Court held in Babulal Parate v. State of Bombay in 1960. The Andhra Pradesh legislature’s rejection of the bifurcation Bill in January 2014, followed by the division that June, is the standing illustration.

Q: Does creating a state require a constitutional amendment?

No. Article 4 of the Constitution provides that a law made under Article 2 or Article 3, containing the necessary amendments of the First Schedule and the Fourth Schedule and any supplemental provisions, shall not be deemed to be an amendment of the Constitution for the purposes of Article 368. A new state is therefore created by ordinary legislation passed by simple majority, without the special majority an amendment needs and without ratification by the states. Constitutional amendments have sometimes accompanied reorganisations for collateral reasons, as the Seventh Amendment accompanied the settlement of 1956 to abolish the old classification of states, and as amendments were needed for the cession of territory and for Sikkim’s terms of entry, but the creation itself never requires one.

Q: What does a reorganisation Act typically contain?

A reorganisation Act follows a standard pattern refined across the Acts of 1956, 2000, 2014, and 2019. It fixes an appointed day from which the new arrangement runs, describes the territories of the successor units, divides representation in the Council of States, the House of the People, and the successor assemblies, and provides for delimitation. It decides whether a High Court will be separate or common, apportions assets and liabilities between the successors, allocates officers and employees with protection for their conditions of service, continues existing laws in force until the successors alter them with a power of adaptation in the interval, provides for pending proceedings, and closes with a time-limited power to remove difficulties. The schedules carry the detail, and the contested heads are usually assets, services, and institutions.

Q: Which commissions shaped state reorganisation?

Three bodies frame the story. The Linguistic Provinces Commission of 1948, chaired by S. K. Dar, reported in December 1948 against forming provinces on a linguistic basis, recommending administrative convenience instead. The JVP Committee of Jawaharlal Nehru, Vallabhbhai Patel, and Pattabhi Sitaramayya reported in April 1949 to substantially the same effect, deferring the question. The States Reorganisation Commission, appointed in December 1953 under the chairmanship of Fazl Ali with H. N. Kunzru and K. M. Panikkar, reported on 30 September 1955 accepting language as a major factor while rejecting the doctrine of one language, one state, and its framework produced the settlement of 1956. Smaller bodies did particular work later, among them the Shah Commission of 1966, which demarcated the Punjabi-speaking and Hindi-speaking areas before the division of Punjab.

Q: Can a state be converted into a Union territory?

The text of Article 3, read with its first explanation, which brings Union territories within most of its clauses, was the basis on which Parliament converted Jammu and Kashmir into two Union territories by the Reorganisation Act of 2019, the first downward conversion of a state in the Union’s history. Whether the power extends that far was challenged in the Article 370 case, and the Constitution Bench, by its judgment of 11 December 2023, did not decide the question, recording the Solicitor General’s assurance that statehood would be restored to Jammu and Kashmir and directing that restoration occur at the earliest opportunity. The question therefore remains open as a matter of decided law, and the matter should be described as undecided rather than resolved in either direction.

Q: How are assets and liabilities divided between successor states?

The reorganisation Act itself apportions them, following conventions that have hardened into a pattern. The public debt of the old state and its financial assets are divided between the successors ordinarily in the ratio of their populations. Land, buildings, and other physical assets generally follow their location, passing to the successor in whose territory they sit. Institutions, corporations, and boards that served the whole of the old state are the hard cases, and the modern Acts list them in schedules, the Ninth and Tenth Schedules of the Andhra Pradesh Act of 2014 being the fullest example, for division or shared use on stated terms. The pattern produces disputes of long duration, because a schedule can assign an institution but cannot divide its staff, its records, and its obligations with the same ease.

Q: What happens to existing laws in a successor state?

They continue. The standard provision of a reorganisation Act keeps every law in force in the old state immediately before the appointed day in force in each successor territory, in the form in which it applied there, until the legislature competent for that territory alters or repeals it. The Acts support continuity with an adaptation power, allowing the successor government, for a limited period, to adapt laws by order to the new map, substituting names, territories, and authorities. The statute books of the successors therefore begin identical and diverge as their legislatures amend at different speeds. The Act of 2019 is the exception that proves the rule, since its Fifth Schedule applied 106 central laws to the new Union territories, repealed 153 state laws, and continued only the remainder.

Q: What majority does Parliament need to create a new state?

A simple majority of the members present and voting in each House, the same majority that passes ordinary legislation. No special majority of the total membership, no two-thirds requirement, and no ratification by state legislatures is needed, because Article 4 declares that a reorganisation law is not a constitutional amendment for the purposes of Article 368. The point is frequently misunderstood, since the consequences of the law are constitutional in scale: it rewrites the First Schedule’s list of states, reallocates seats in the Fourth Schedule, and reconstitutes legislatures. The Constitution classifies the instrument by its form rather than its effects, and in its form a reorganisation Act is an ordinary Bill that becomes law on presidential assent after passage by both Houses.

Q: What role does the President play in creating a new state?

The President appears at three points in the process, each formal in character and exercised on the advice of the Council of Ministers. First, no reorganisation Bill may be introduced in either House except on the President’s recommendation, which makes the measure a government Bill by constitutional design. Second, where the Bill affects the area, boundaries, or name of a state, the President refers it to that state’s legislature for its views and specifies the period within which they are to be expressed, with power to allow a further period. Third, the Bill becomes an Act on the President’s assent. The President also appoints the Governors of the successor states and, in particular reorganisations, has exercised ancillary functions such as adapting special constitutional provisions to the new units.

Q: How much time does a state legislature get to express its views on a reorganisation Bill?

As much time as the President’s reference specifies, and no more than the President allows. The proviso to Article 3 fixes no period of its own: the Bill is referred for expressing views within such period as may be specified in the reference, or within such further period as the President may allow. Practice has measured the period in weeks; the reference of the Andhra Pradesh Bill in December 2013 allowed six weeks and was extended once before the Assembly answered on the final day. When the period expires, with or without an answer, the condition stands satisfied and Parliament proceeds. The state legislature cannot extend its own time, cannot condition the process on its answer’s content, and cannot convert delay into a veto.

Q: Can Parliament change the name of a state?

Yes. Clause (e) of Article 3 empowers Parliament by law to alter the name of any state, and because a change of name affects the state, the Bill travels the same road as any reorganisation: presidential recommendation, reference to the state legislature for its views, passage by simple majority, and amendment of the First Schedule. The power has been used for the changes by which Madras became Tamil Nadu under the Madras State (Alteration of Name) Act, 1968, Uttaranchal became Uttarakhand under the Act of 2006, and Orissa became Odisha under the Act of 2011, the last accompanied by a constitutional amendment because the language’s name in the Eighth Schedule changed from Oriya to Odia with it. A name change is the lightest exercise of the widest power in the field.

Q: Can two states share a common High Court after a reorganisation?

Yes, and reorganisation Acts have repeatedly arranged it. Article 231 of the Constitution empowers Parliament to establish a common High Court for two or more states, and the choice between separate courts and a common court is one of the standard decisions a reorganisation Act records. The Punjab and Haryana High Court at Chandigarh has served two states since the division of 1966. The High Court of Judicature at Hyderabad served Andhra Pradesh and Telangana in common from the appointed day in 2014 until separate courts were constituted on 1 January 2019, leaving the Hyderabad court to Telangana and giving Andhra Pradesh its own court at Amaravati. The High Court of Jammu and Kashmir likewise continued as the common court of the two Union territories created in 2019.

Q: What happens to inter-state agreements when a state is reorganised?

They do not lapse. The reorganisation Acts allocate the old state’s rights and obligations, including those arising under its agreements with other states and with the Union, between the successors, ordinarily by reference to the territory and subject matter the agreement concerns, so that the successor within whose field the agreement falls steps into the old state’s place under it. Where an agreement served the whole of the old state, as river-water and power-sharing arrangements characteristically do, the division converts an internal allocation into an inter-state one, and the agreement’s terms become the starting point of the successors’ relations rather than their end. The sharing of the Ravi and Beas waters, fixed in the settlement surrounding the Punjab reorganisation of 1966 and restated in the agreement of 1981, fed the Sutlej-Yamuna Link dispute between Punjab and Haryana for decades on exactly this logic.

Q: Can Parliament cede Indian territory to another country by ordinary law?

No. Article 3 governs the rearrangement of territory inside the Union and does not extend to giving Indian territory to a foreign state. In its advisory opinion In re Berubari Union, delivered in 1960 on a reference concerning the Nehru-Noon Agreement with Pakistan, the Supreme Court held that cession of Indian territory alters the territory of India described in Article 1 and can be effected only by a constitutional amendment under Article 368. The Ninth Amendment of 1960 was accordingly enacted to implement that agreement, and the same route was taken for the exchange of enclaves with Bangladesh under the Land Boundary Agreement, which the Constitution (One Hundredth Amendment) Act, 2015 carried into effect. The boundary of the Union is the one line in this field that an ordinary law cannot move.

Q: Can a state reorganisation law be challenged in court?

Yes, but the grounds are narrow and no reorganisation Act has ever been struck down. The decided cases fix the available lines of attack. Compliance with the proviso to Article 3 can be examined, but the requirement is satisfied by the initial reference, and later amendments to the Bill need no fresh reference provided they are germane to the proposal and not its direct negative, as Babulal Parate v. State of Bombay settled in 1960; Article 122 separately bars questioning parliamentary proceedings for irregularity of procedure. A law that crosses the frontier into cession exceeds the power altogether, on the Berubari opinion. Beyond the edges, the width of the power leaves a court little purchase: the wisdom of a boundary, the adequacy of a consultation, and the merits of a division are matters the Constitution commits to Parliament.

Q: How are Rajya Sabha seats divided between successor states?

The reorganisation Act divides them itself. Article 4 authorises the Act to amend the Fourth Schedule, which allocates seats in the Council of States among the states, and the Act splits the parent state’s allocation between the successors broadly following their territories and populations. Madhya Pradesh’s sixteen seats became eleven for Madhya Pradesh and five for Chhattisgarh in 2000, and undivided Andhra Pradesh’s eighteen became eleven for Andhra Pradesh and seven for Telangana in 2014. Sitting members must also be allotted, since a Council member represents a whole state rather than a constituency, and the Acts deem the sitting members elected for the successor states in numbers matching the new allocation; in 2014 the allotment of individual members between the two states was carried out by a draw of lots.

Q: What is the difference between admitting a new state under Article 2 and forming one under Article 3?

The two articles govern opposite sides of the Union’s boundary. Article 2 empowers Parliament by law to admit into the Union, or establish, new states on such terms and conditions as it thinks fit, and it concerns territory that is not already part of India, territory acceding or acquired from outside. Article 3 empowers Parliament to rearrange territory that is already within the Union, forming states from states, altering areas, boundaries, and names. The distinction mattered most visibly for Sikkim, which entered from outside through the Article 2 side of the scheme, with constitutional amendments in 1974 and 1975 writing its special terms into the Constitution as Article 371F. Territory already inside the Union, by contrast, is rearranged under Article 3 by ordinary law alone, with no terms to negotiate and no consent to obtain.

Q: Does Parliament need a referendum before dividing a state?

No. Neither the Constitution nor any statute requires a referendum, a plebiscite, or any direct vote of the people of the affected territory before a state is created, divided, merged, or renamed. The wishes of the people enter the process politically, through movements, elections, and the views the affected state legislature expresses on the reference, but they never enter it as a decision that binds. The single departure in the record was arranged outside any legal requirement: the opinion poll held in Goa on 16 January 1967, in which the territory’s voters chose continued Union territory status over merger with Maharashtra, a political device whose result the Union government honoured. Other federations, Australia and Germany among them, write the referendum into the constitutional process itself. India does not.

Q: Can a Union territory be made into a state by Parliament?

Yes, by the same ordinary law that performs every other operation in this field. The first explanation to Article 3 brings Union territories within the article’s clauses, and Parliament’s practice has made elevation a standard career for a territory: Himachal Pradesh became a state in 1971, Manipur, Tripura, and Meghalaya in 1972 under the North-Eastern Areas (Reorganisation) Act, 1971, and Mizoram, Arunachal Pradesh, and Goa in 1987. The Act amends the First Schedule to move the unit from the territories to the states, settles its representation and its High Court, and the territory’s administrator gives way to a Governor and a responsible ministry. No state’s territory is taken in an elevation, so the reference the proviso requires for changes to a state has no application, and the debate is between the territory’s claim and the Union’s judgment alone.
