Union and Its Territory: Articles 1 to 4 and How Parliament Redraws the Map

Exactly one real past-year Prelims question maps to this chapter as its own topic: 2025 (three statements about how Nagaland, Tripura and Arunachal Pradesh individually became States, which only resolves if you know the mechanism, ordinary law under Article 3 versus a constitutional amendment, behind each). That thin count undersells how often this chapter's material surfaces, because Articles 1 to 4 are the constitutional engine behind nearly every "which States were formed when, under what Act" fact UPSC tests elsewhere: J&K's 2019 reorganisation, Telangana's 2014 creation, the 2000 trio of Chhattisgarh, Jharkhand and Uttarakhand, and the 1956 linguistic map redraw. The Federal System note on this site touches Article 1's wording and Article 3's existence briefly, as one example inside a broader argument about India being "quasi-federal." This note does the opposite: Articles 1 to 4 as a complete chapter in their own right, article by article, and then the same logic extended to Union Territories under Articles 239, 239A and 239AA, including Delhi's special arrangement and the 2018 Supreme Court judgment settling how far its elected government's authority runs.

This chapter's material overlaps with NCERT Class 11, Indian Constitution at Work, Chapter 7 (Federalism). This note goes further than that chapter's coverage.

Article 1: naming the Union and defining its territory

Article 1(1) states: "India, that is Bharat, shall be a Union of States." "Union," not "Federation," is a deliberate drafting choice, Dr. B.R. Ambedkar explained in the Constituent Assembly that it was chosen precisely to signal that the Union is not the result of an agreement among the States, and no State has the right to secede from it. Article 1(2) then says the States and territories thereof "shall be as specified in the First Schedule," so the First Schedule is the operative list Article 1 itself points to, not decoration.

Article 1(3) draws a distinction worth reading slowly, because it is tested as a trap: "the territory of India shall comprise (a) the territories of the States, (b) the Union territories specified in the First Schedule, and (c) such other territories as may be acquired." "The territory of India" is thus broader than, and capable of growing beyond, what the First Schedule currently lists, since clause (c) leaves room for future acquisition. "India," as the Union under Article 1(1), is the political entity; "the territory of India" under Article 1(3) is the geographic extent it currently governs, and the two are not synonyms even though the article uses "India" for both. A newly acquired territory becomes part of "the territory of India" immediately, by the fact of acquisition; it only formally becomes a State or Union Territory once Parliament legislates it into the First Schedule. A statement conflating "the territory of India" with "the Union of States" reads fine on a first pass but is not what Article 1 says.

Article 2: admitting or establishing new States into the Union

Article 2 reads: "Parliament may by law admit into the Union, or establish, new States on such terms and conditions as it thinks fit." "Admit" covers a territory that already exists as a political unit somewhere, being brought into the Union, historically the route for princely states and other territories that existed before joining India. "Establish" covers Parliament creating a wholly new State that did not exist as a distinct unit before. Both routes are ordinary law, a simple Bill needing only a simple majority in each House, and Parliament sets whatever "terms and conditions" it thinks fit, wide and largely unreviewable discretion.

The point to fix precisely, the single most common source of confusion in this chapter: Article 2 deals with territory new to the Union entirely, land not already part of an existing Indian State. Article 3, next, deals with reshuffling territory already inside the Union among its existing States.

Article 3: Parliament's power to redraw the internal map

Article 3 is this chapter's real centre of gravity, both constitutionally and for the exam. It gives Parliament the power, by ordinary law, to:

• (a) 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;
• (b) increase the area of any State;
• (c) diminish the area of any State;
• (d) alter the boundaries of any State;
• (e) alter the name of any State.

Two Explanations sharpen the scope. Explanation I says that in clauses (a) to (e), "State" includes a Union Territory, so Parliament can carve a new State out of Union Territory land, or merge Union Territory land into a State, using the same machinery. Explanation II extends clause (a) further: the power to "form" a new State or Union Territory includes uniting a part of any State or Union Territory to any other State or Union Territory.

The procedure, and where the real exam traps sit. The proviso to Article 3 lays down a precise two-step gate before any such Bill can even be introduced. First, no Bill for this purpose may be introduced in either House of Parliament except on the recommendation of the President, a hard precondition on introduction, not merely on passage. Second, if the Bill affects the area, boundaries or name of any State, the President must refer it to that State's Legislature, for that Legislature to express its views within whatever period the President specifies (or a further period the President may allow); only once that period has expired can the Bill actually proceed.

The trap UPSC returns to repeatedly sits inside that second step: the State Legislature's views are sought, but they do not bind Parliament in any way. Parliament can accept, modify, or reject them entirely, and still pass the Bill by an ordinary simple majority regardless of what the affected State says, precisely what marks Article 3 as one of the sharpest unitary levers in an otherwise quasi-federal Constitution: no classical federation lets its national legislature redraw a constituent unit's borders over that unit's own objection using nothing stronger than an ordinary law. Also worth holding: since the proviso says "State" there does not include a Union Territory, no comparable consultation step is required before Parliament alters a Union Territory's boundaries.

A second trap, exactly the structural confusion the 2025 PYQ probes: Article 2 is for territory new to the Union; Article 3 is for reshuffling territory already inside it. Every State reorganisation covered later in this note was carried out under Article 3, because in every case the new units were carved from territory already belonging to an existing Indian State, never freshly acquired or admitted territory.

Article 4: why an Article 2 or Article 3 law is never a "constitutional amendment"

Article 4(1) says any law made under Article 2 or Article 3 must contain whatever provisions are necessary to amend the First Schedule (States and Union Territories) and the Fourth Schedule (Rajya Sabha seats), to give effect to the law, and may also contain "supplemental, incidental and consequential provisions" Parliament thinks necessary, including provisions on representation in Parliament and in the affected State Legislature or Legislatures.

Article 4(2) is worth memorising verbatim, because it is exactly what an exam trap is built around: "No such law as aforesaid shall be deemed to be an amendment of this Constitution for the purposes of article 368." Even though such a law literally changes the text of two Schedules, an amendment in substance, it is not treated as one for Article 368's purposes: no special majority (two-thirds present and voting, plus a majority of total membership, in each House) and no State ratification, only the ordinary law-making procedure subject to Article 3's own Presidential-recommendation and State-reference steps. This is the design choice that lets Parliament redraw India's map as often as circumstance demands without Article 368's toughest-route friction. The identical formula recurs twice more, in Article 239A(2) and Article 239AA(7)(b), and that repeated pattern is itself worth a mark on a well-built statement question.

The reorganisation of India: from 1956 to 2019

With the mechanism fixed, the standard sequence of reorganisations UPSC tests as factual recall follows directly from it. Every event below was carried out under Article 3.

The States Reorganisation Act, 1956. India's post-independence map was, at first, a patchwork organised into Part A, B, C and D States bearing little relation to linguistic or cultural boundaries. Demands for linguistically organised States led the Government to appoint the States Reorganisation Commission in December 1953, chaired by Justice Fazl Ali with H.N. Kunzru and K.M. Panikkar as members. The Commission's 1955 report recommended States be organised principally along linguistic lines, and Parliament gave that legal effect through the States Reorganisation Act, 1956, reorganising the country into 14 States and 6 Union Territories and replacing the old classification entirely. This remains the single most consequential reorganisation event in India's constitutional history.

The 2000 creation of Chhattisgarh, Jharkhand and Uttarakhand. Three new States were carved out of existing ones in quick succession: Chhattisgarh from Madhya Pradesh, Uttarakhand from Uttar Pradesh, and Jharkhand from Bihar, each by its own separate Article 3 Act, reflecting long-running regional demands grounded in distinct cultural identity, geography, and a sense of developmental neglect within the parent State.

The Andhra Pradesh Reorganisation Act, 2014. This Act bifurcated Andhra Pradesh, creating Telangana as a new State, with Hyderabad as a joint capital for both successor States for a transitional period. This is the most recent instance of a full State being newly created, as opposed to a State being reorganised into Union Territories, the 2019 case below.

The Jammu and Kashmir Reorganisation Act, 2019. Parliament, under Article 3, reorganised the erstwhile State of Jammu and Kashmir into two Union Territories: Jammu and Kashmir (with its own Legislative Assembly) and Ladakh (without one). The Act received Presidential assent on 9 August 2019 and took effect from the "appointed day," 31 October 2019. Section 13 of the Act extends Article 239A, otherwise applicable to Puducherry, to the new Union Territory of Jammu and Kashmir, supplying its Assembly with a constitutional basis. This is the only reorganisation here that converted a full State into two Union Territories rather than creating a new State, which is why the note now turns to a Union Territory's constitutional position.

Union Territories: the administrative law of Articles 239 and 239A

A State and a Union Territory are not variations on the same constitutional category; they sit under different Parts of the Constitution with different default administrative logic. Article 239(1) supplies the default rule: "Save as otherwise provided by Parliament by law, every Union territory shall be administered by the President acting, to such extent as he thinks fit, through an administrator to be appointed by him." Unlike a State, which has its own directly elected government, a Union Territory's baseline position is direct central administration through an appointed Administrator, not autonomous elected executive power. Article 239(2) allows the President to appoint a State's own Governor as the Administrator of an adjoining Union Territory, exercising that function independently of their own State's Council of Ministers.

Article 239A is the exception to that bare, purely appointed model. It allows Parliament to create, by law, for certain Union Territories, "a body, whether elected or partly nominated and partly elected, to function as a Legislature," or a Council of Ministers, or both, with whatever constitution, powers and functions the law specifies. Puducherry is the standing textbook example, and the same provision was extended by the 2019 Act to the new Union Territory of Jammu and Kashmir. Article 239A(2) repeats the Article 4 pattern, not deemed a constitutional amendment for Article 368 purposes. Hold the exam distinction: Article 239A creates a Legislature entirely at Parliament's own discretion, whether to legislate at all and in whatever design it picks, structurally weaker than what Article 239AA provides for Delhi.

Article 239AA: the special, more elaborate framework for Delhi

Delhi's position is deliberately more developed than the general Article 239A model, set out in its own dedicated article, inserted by the Constitution (Sixty-ninth Amendment) Act, 1991. From the date that amendment commenced, the Union Territory of Delhi was renamed the National Capital Territory of Delhi, and its Administrator was redesignated the Lieutenant Governor. Article 239AA(2) establishes a Legislative Assembly for the Territory, directly elected, with seat count, Scheduled Caste reservation, and delimitation regulated by a law of Parliament.

Article 239AA(3)(a) defines exactly what the Assembly can legislate on, the clause worth fixing precisely for the exam: laws "with respect to any of the matters enumerated in the State List or in the Concurrent List in so far as any such matter is applicable to Union territories, except matters with respect to Entries 1, 2 and 18 of the State List." Entries 1, 2 and 18 are, respectively, Public Order, Police and Land. So the elected Assembly holds the whole of the State and Concurrent List applicable to Union Territories, minus those three subjects, which stay with the Union. Article 239AA(3)(b) preserves Parliament's own overriding power to legislate for the Territory regardless, and (3)(c) gives Parliament's law priority over a conflicting Assembly law, unless that law was reserved for and received the President's assent.

Article 239AA(4) provides for a Council of Ministers, headed by the Chief Minister, "to aid and advise the Lieutenant Governor," with a proviso: "in the case of difference of opinion between the Lieutenant Governor and his Ministers on any matter, the Lieutenant Governor shall refer it to the President for decision and act according to the decision given thereon," and pending that decision the Lieutenant Governor may act unilaterally only where the matter is, in his own opinion, "so urgent that it is necessary for him to take immediate action." Article 239AA(7)(b) carries the same Article 4 exclusion once more.

Government of NCT of Delhi v Union of India (2018): how far the elected government's authority actually runs

That proviso, "difference of opinion... on any matter," is broad enough on a bare reading to let a Lieutenant Governor treat virtually every decision of the elected Council of Ministers as a referable "difference," gutting the Assembly's day-to-day executive authority regardless of its legislative competence. That precise question reached a five-judge Supreme Court Constitution Bench, which delivered its judgment on 4 July 2018 in Government of NCT of Delhi v. Union of India.

The Bench's own recorded conclusions ("in seriatim," point by point) settle the question with unusual directness. On the Lieutenant Governor's authority: "The Lieutenant Governor has not been entrusted with any independent decision-making power. He has to either act on the 'aid and advice' of Council of Ministers or he is bound to implement the decision taken by the President on a reference being made by him." On the referral proviso's scope: "The words 'any matter'... cannot be inferred to mean 'every matter.' The power of the Lieutenant Governor under the said proviso represents the exception and not the general rule," to be exercised only in exceptional circumstances, never mechanically to refer every decision to the President. The Court also held that the Council of Ministers' executive power is co-extensive with the Assembly's legislative competence, and that keeping the Lieutenant Governor informed of its decisions does not amount to requiring his concurrence. Separately, the judgment described Delhi's status as sui generis, "of its own kind," a class apart from both an ordinary State and an ordinary Union Territory; the National Capital Territory is not a State and the Lieutenant Governor is not a Governor.

Quick revision points

• Article 1: "Union of States," not "Federation." States/UTs listed in the First Schedule. "The territory of India" (1(3): States, UTs, plus territory that may be acquired) is broader than, and not synonymous with, "India" as the Union itself.
• Article 2 (territory new to the Union): admit or establish new States, on terms Parliament thinks fit, by ordinary law.
• Article 3 (territory already inside the Union, reshuffled): form a new State, increase/diminish area, alter boundaries, or alter name, by ordinary law. Explanation I: "State" includes a UT (except in the proviso). Core trap: the Bill needs the President's prior recommendation to be introduced, and if it affects a State's area, boundaries or name, the President refers it to that State's Legislature for its views within a specified period. Those views are advisory only; Parliament may accept, modify, or reject them and still pass the Bill by simple majority.
• Article 4: such a law amends the First Schedule (States/UTs) and Fourth Schedule (Rajya Sabha seats) as needed, plus whatever incidental provisions Parliament deems necessary, and is never deemed a constitutional amendment for Article 368, no special majority or State ratification. The identical exclusion recurs in Article 239A(2) and Article 239AA(7)(b).
• Reorganisation timeline: States Reorganisation Act, 1956 (14 States, 6 UTs, following the States Reorganisation Commission's 1955 report under Justice Fazl Ali) to Chhattisgarh/Jharkhand/Uttarakhand (2000, from Madhya Pradesh/Bihar/Uttar Pradesh) to the Andhra Pradesh Reorganisation Act, 2014 (Telangana) to the Jammu and Kashmir Reorganisation Act, 2019 (assented 9 August 2019, effective 31 October 2019, splitting J&K into the UTs of Jammu and Kashmir, with a Legislature via Article 239A, and Ladakh, without one).
• Article 239: default rule, a UT is administered by the President through an appointed Administrator. Article 239A: Parliament may by law create an elected/partly elected Legislature and/or Council of Ministers for a UT (Puducherry is the standing example; extended to J&K's UT in 2019).
• Article 239AA: Delhi's own, more elaborate framework. Assembly legislates on State List and Concurrent List subjects except Police, Public Order and Land (Entries 1, 2, 18 of the State List). Council of Ministers aids and advises the Lieutenant Governor; a genuine difference of opinion goes to the President.
• GNCTD v Union of India (2018), five-judge Constitution Bench: the Lieutenant Governor has no independent decision-making power; the proviso's "any matter" does not mean "every matter," an exception for genuine differences, not a general veto; Delhi's status is sui generis, neither a State nor an ordinary Union Territory.

Hold the two structural traps this chapter is built around: Article 2 (new territory) versus Article 3 (redrawing existing territory), and Article 3's proviso giving a State a voice, never a veto. Everything else, the 1956-to-2019 timeline and the Union Territory framework, is the same Article 3/4 logic applied to specific, dated events.
