Polity · Constitutional Framework
Covers Articles 1–4 of Part I of the Constitution: India as a Union of States, Parliament's power to reorganise states, the evolution of states and union territories since independence, and key constitutional amendments related to territorial changes.
Articles 1 to 4, placed under Part I of the Constitution, define the nature of the Indian Union and lay down the rules governing its territorial composition. These provisions settle two foundational questions: what India is called, and how its territory can be altered.
The Constituent Assembly could not reach a consensus on what to call the country. One faction favoured the ancient name Bharat, while another preferred the modern international name India. The deadlock was resolved by adopting both names — 'India, that is, Bharat' — giving constitutional standing to each.
Article 1 designates India a 'Union of States', not a 'Federation of States'. Dr. B.R. Ambedkar explained this choice on two grounds:
The Union is therefore described as indestructible. States exist purely for administrative convenience — the country is an integral whole that has been divided, not a collection of units that have come together.
Under Article 1, the territory of India encompasses:
Key Distinction: 'Territory of India' is broader than 'Union of India'. The Union of India covers only states (which share legislative and executive powers with the Centre), while Territory of India additionally includes union territories and acquired territories — both of which are directly administered by the Central government.
As a sovereign state, India can acquire territory through modes recognised by international law: cession (by treaty, purchase, gift, lease or plebiscite), occupation of hitherto unoccupied areas, conquest, or subjugation. Territories acquired after 1950 include Dadra and Nagar Haveli, Goa, Daman and Diu, Puducherry, and Sikkim.
Parliament is empowered to admit (states already in existence outside India) or establish (entirely new states not previously in existence) new states on whatever terms and conditions it considers appropriate.
Parliament can:
Procedural Conditions:
The Constitution does not guarantee the territorial integrity or continued existence of any state. Parliament can unilaterally redraw state boundaries or even abolish a state. The Union, however, is indestructible.
This contrasts sharply with the USA, where the federal government cannot alter state boundaries without the concerned state's consent — making it 'an indestructible union of indestructible states'.
Laws passed under Articles 2 and 3 are not considered constitutional amendments under Article 368. They can therefore be passed by a simple majority through the ordinary legislative process — not the special majority needed for constitutional amendments.
A major constitutional issue arose when the Central government decided to transfer the Berubari Union territory (West Bengal) to Pakistan. The Supreme Court (1960) held that Parliament's power under Article 3 to diminish state areas does not include ceding Indian territory to a foreign country. Such cession requires a constitutional amendment under Article 368.
Consequently, the 9th Constitutional Amendment Act (1960) was enacted to transfer Berubari to Pakistan.
In contrast, the Supreme Court ruled in 1969 that settling a boundary dispute with another country does not require a constitutional amendment — it can be done by executive action since no cession of territory is involved.
This amendment gave effect to the Land Boundary Agreement between India and Bangladesh:
Background: The India–East Pakistan boundary was set by the Radcliffe Award (1947), partly revised by the Bagge Award (1950), and addressed again by the Nehru-Noon Agreement (1958). The 9th Amendment (1960) could not be operationalised for former East Pakistan. The 1974 India-Bangladesh Land Boundary Agreement and its 2011 Protocol finally resolved the outstanding issues.
India comprised two categories of political units:
Of 552 princely states within India's geographic boundaries, 549 joined India voluntarily. Three holdouts — Hyderabad, Junagarh, and Kashmir — were eventually integrated:
The original Constitution classified states into four categories:
| Category | Nature | Examples |
|---|---|---|
| Part A | Erstwhile Governor's Provinces of British India | Assam, Bihar, Bombay, Madras |
| Part B | Erstwhile princely states with legislatures | Hyderabad, Mysore, Rajasthan |
| Part C | Chief Commissioner's Provinces + some princely states (centrally administered) | Ajmer, Delhi, Manipur |
| Part D | The Andaman and Nicobar Islands alone | Andaman and Nicobar Islands |
Total: 29 units.
Appointed in June 1948 to assess linguistic reorganisation, the Dhar Commission submitted its report in December 1948 and recommended reorganisation based on administrative convenience, not language. This triggered widespread resentment.
The Indian National Congress formed its own committee comprising Jawaharlal Nehru, Vallabhbhai Patel and Pattabhi Sitaramayya (hence JVP). It submitted its report in April 1949 and formally rejected language as the basis for state reorganisation. Notably, the JVP Committee had no chairman or convenor.
Despite the rejection of linguistic basis, popular agitation — particularly the death of Potti Sriramulu after a 56-day hunger strike — forced the government's hand. In October 1953, Andhra State was carved out of Madras State, separating Telugu-speaking areas. It was India's first linguistic state; Kurnool was its capital and the High Court was at Guntur.
Appointed in December 1953, this three-member States Reorganisation Commission was chaired by Fazl Ali, with K.M. Panikkar and H.N. Kunzru as members. Its September 1955 report:
The government accepted the Commission's recommendations with minor changes. The 7th Constitutional Amendment Act (1956) and the States Reorganisation Act (1956) together:
| State / UT | Year | How Created |
|---|---|---|
| Maharashtra & Gujarat | 1960 | Bombay state bifurcated on linguistic lines (Marathi/Gujarati); Gujarat became 15th state |
| Dadra and Nagar Haveli | 1961 | Liberated from Portugal (1954); made UT by 10th Constitutional Amendment Act, 1961 |
| Goa, Daman & Diu | 1961/62 | Acquired from Portugal by police action; made UT by 12th Constitutional Amendment Act, 1962 |
| Puducherry | 1962 | French territories handed over in 1954; made UT by 14th Constitutional Amendment Act, 1962 |
| Nagaland | 1963 | Separated from Assam; 16th state (State of Nagaland Act, 1962, effective 1 Dec 1963) |
| Haryana & Chandigarh | 1966 | Punjab bifurcated on Shah Commission recommendation; Haryana = 17th state, Chandigarh = UT |
The demand for a 'Sikh Homeland' (Punjabi Subha) by the Akali Dal under Master Tara Singh led to the Punjab Reorganisation Act (1966). The Shah Commission recommended:
| Old Name | New Name | Year |
|---|---|---|
| United Provinces | Uttar Pradesh | 1950 |
| Madras | Tamil Nadu | 1969 |
| Mysore | Karnataka | 1973 |
| Laccadive, Minicoy & Amindivi Islands | Lakshadweep | 1973 |
| Delhi (UT) | National Capital Territory of Delhi | 1992 (69th Amendment Act, 1991) |
| Uttaranchal | Uttarakhand | 2006 |
| Pondicherry | Puducherry | 2006 |
| Orissa | Odisha | 2011 |
Note: Delhi was redesignated as NCT without being made a full state.
