The Union government has circulated draft copies of three proposed Bills to MPs ahead of a special parliamentary session. The legislation would increase Lok Sabha seats from the current 543 to 850, triggering a major delimitation exercise. The proposals raise constitutional questions about Articles 81, 82, and 170, which govern the composition of Parliament and state legislatures. Southern states fear losing political representation due to their better population control record compared to northern states.

India's Lok Sabha seat count has been frozen at 543 since 1977, pursuant to the 42nd Constitutional Amendment, which suspended delimitation until after the first Census following 2000. The 84th Amendment (2001) extended this freeze until after the first Census following 2026. This freeze was a deliberate constitutional bargain to prevent states that successfully controlled population growth — primarily southern states — from being penalised with reduced parliamentary representation.

Article 81 of the Constitution governs the composition of the House of the People, stipulating that total seats shall not exceed 550. Importantly, this means expanding to 850 would itself require a constitutional amendment under Article 368, not merely ordinary legislation. Article 82 mandates readjustment of constituencies after each Census (delimitation), while Article 170 governs state legislative assembly composition.

The Delimitation Commission, established under the Delimitation Commission Act 2002, carries out this exercise under the superintendence of the Election Commission. Previous Delimitation Commissions were constituted in 1952, 1963, 1973, and 2002.

The constitutional tension here is acute: expanding seats requires amending Article 81 itself, which is a basic structural provision, and any formula that allocates seats strictly by population could disadvantage states like Tamil Nadu, Kerala, Andhra Pradesh, and Telangana. This raises questions about federalism — itself considered part of the basic structure since Kesavananda Bharati v. State of Kerala (1973). The examiner will test whether aspirants can identify which constitutional articles are engaged, what amendment procedure is required, and what the basic structure doctrine's relevance is.
