Discuss the constitutional mechanism of the 1971-Census-based seat freeze and evaluate the arguments for and against its further extension.

Article 82 requires readjustment of Lok Sabha seats after every census, yet India's seat allocation still rests on the 1971 Census. Successive amendments have converted a temporary pause into a durable federal bargain — one now central to the delimitation debate.

The constitutional mechanism

• The 42nd Amendment (1976) froze the number of Lok Sabha and Assembly seats allotted to each State on the 1971 Census, until publication of the first census after 2000 [2].
• The 84th Amendment (2001) extended the freeze to the first census after 2026, amending Articles 81, 82, 170, 330 and 332; SC/ST reserved seats were reworked on 2001 Census data [4].
• Only inter-State allocation is frozen; intra-State boundaries were redrawn by the 2002 delimitation exercise.
• Stated rationale: a motivational measure enabling States to pursue population stabilisation [2].

Case for further extension

• Rewards demographic performance: a shift to 2011 Census data would reduce Tamil Nadu from 39 to 32 seats while Uttar Pradesh rises from 80 to 89 [1] — penalising States that stabilised fertility earliest.
• Protects federal balance, preserving the southern and smaller States' voice in national policymaking and in the Electoral College.
• Sustains Centre-State trust, since population-linked losses compound existing grievances over resource devolution.

Case against further extension

• Erodes "one person, one vote, one value", the proportionality principle underlying Article 81; malapportionment widens with every decade of freeze.
• Vast constituency sizes weaken representative accountability and MPs' service capacity.
• Stalls women's reservation under the 106th Amendment, whose one-third quota takes effect only after a census and consequent delimitation [3].
• Population control now tracks development and female literacy more than seat incentives.

Extension buys federal comfort at rising representational cost. A calibrated path — enlarging the House so no State loses seats in absolute terms, guaranteeing shares through a constitutional schedule, and building consensus via the Inter-State Council — can reconcile equality of vote with federal fairness. The 131st Amendment Bill's defeat for want of a two-thirds majority [1] confirms that consensus, not arithmetic, is the real precondition.
