Discuss the constitutional provisions governing delimitation of constituencies in India and the political economy of freezing versus unfreezing seat numbers.

Delimitation — the readjustment of seat allocation and constituency boundaries after each census under Article 82 — has returned to the centre of debate with the Delimitation Bill, 2026 proposing to raise Lok Sabha strength to 850 [2]. It is as much a question of federal bargaining as of constitutional text.

Constitutional framework

• Article 81 fixes the composition of the Lok Sabha and requires seats to be allotted to States in proportion to population; Article 170 governs Assembly strength.
• Article 82 mandates readjustment after every census, by a Delimitation Commission constituted under a law of Parliament; Article 329(a) bars courts from questioning delimitation laws and orders.
• Articles 330 and 332 provide reservation of seats for SCs and STs, now supplemented by the 106th Amendment, 2023, which reserves one-third of seats for women effective after the first census following its commencement and the delimitation based on it [3].
• The 42nd Amendment (1976) froze allocation at 1971 levels; the 84th Amendment (2001) extended the freeze on State-wise allocation until the first census after 2026, permitting only boundary readjustment [1].

The case for continuing the freeze

• It protects States that succeeded in population control, whose share of national population has fallen; the Congress has sought a 25-year freeze at 543 seats and existing State shares, with women's quota from 2029 [4].
• It sustains federal trust, already strained by fiscal devolution disputes.

The case for unfreezing

• Prolonged freeze causes malapportionment — widely unequal voter-to-MP ratios diluting "one person, one vote".
• A larger House (815 State + 35 UT seats) means smaller constituencies and closer representation, and would unlock women's reservation without waiting for the 2027 Census [2].

Both positions defend legitimate constitutional values — equality of the vote and federal equity. A negotiated path — an all-party consultative process, phased or capped reallocation so no State loses absolute seats, and compensating strength for smaller States in the Rajya Sabha — would allow representation to be updated while preserving cooperative federalism.
