The decision to conduct Population Census-2027 has reopened the debate on delimitation in India. Discuss its various aspects. (2025, 20 Marks)
Delimitation is the readjustment of the number of seats allotted to each state and the redrawing of constituency boundaries after a census, carried out by an independent Delimitation Commission whose orders carry the force of law and are largely shielded from judicial challenge (Article 329(a)). Census 2027 — enumeration reference date 1 March 2027 — is the “first census after 2026” to which the seat freeze was tied, so it has reopened a question at once constitutional, federal, fiscal and social.
The constitutional frame
- Article 81 fixes the size of the Lok Sabha; Articles 82 and 170 require readjustment of Lok Sabha and assembly seats after every census, under laws made by Parliament (Article 327); Articles 330 and 332 reserve seats for SCs and STs in proportion to their population.
- Delimitation Commissions were set up in 1952, 1963, 1973 and 2002; the last, under Justice Kuldip Singh, redrew boundaries (effective 2008) without changing state totals.
- The 42nd Amendment (1976) froze seat allocation on the 1971 census to avoid penalising family planning; the 84th Amendment (2001) extended the freeze to the first census after 2026, while allowing boundaries within states to be redrawn on later census data.
Representational equality versus federal balance
- B. R. Ambedkar’s ideal of “one man one vote and one vote one value” (1949) is already strained. Milan Vaishnav and Jamie Hintson (Carnegie, 2019) found an Uttar Pradesh MP representing nearly 3 million people against 1.8 million in Tamil Nadu.
- Reallocating a 543-seat House on projected 2026 population, Bihar and Uttar Pradesh would gain 21 seats while Kerala and Tamil Nadu lose 16; in an 848-seat House where no state loses, Uttar Pradesh would hold 143.
- The southern case: states that achieved the demographic transition, and contribute disproportionately to national revenue, would lose political weight to the Hindi heartland — a federal rather than partisan grievance.
The fiscal twin
Population also drives Finance Commission formulas. The Sixteenth Finance Commission weights 2011 population at 17.5 per cent and “demographic performance” at 10 per cent — the same dispute over seats and money.
The social justice dimension
- Fresh data will readjust SC/ST reserved seats (84 and 47 in the Lok Sabha since 2008).
- Caste enumeration, the first since 1931, will fuel demands for proportional OBC political representation.
- The 106th Amendment (2023) makes women’s one-third reservation wait for census and delimitation, pushing it realistically into the 2030s.
The political trajectory
- A Joint Action Committee of southern and allied states formed in March 2025 against population-based redistribution.
- The Constitution (131st Amendment) Bill, 2026 — raising the Lok Sabha ceiling from 550 to 850, letting Parliament decide the timing of delimitation and the census used, and de-linking women’s reservation — was negatived in the Lok Sabha on 17 April 2026 (298–230), short of two-thirds; the companion Delimitation Bill was not proceeded with.
- The 31st Southern Zonal Council (Mahabalipuram, August 2026) pressed for a 543-seat freeze for 25 more years.
Options
- Extend the freeze: protects federal balance but entrenches malapportionment.
- Enlarge the House so that no state loses: softens losses but magnifies northern weight and strains deliberation.
- Degressive proportionality, as in the European Parliament: smaller states are over-represented by formula.
- Strengthen the Rajya Sabha as a genuine chamber of states, with more balanced representation, so the Lok Sabha can follow population.
- Redraw boundaries within states now, deferring inter-state reallocation.
Conclusion
Delimitation sets democratic equality against federal trust. Neither a permanent freeze nor a mechanical reallocation is sustainable; the defeat of the 131st Amendment shows that change needs consensus — most plausibly an enlarged House paired with a stronger federal second chamber and devolution that does not penalise demographic success.
