What Happened
- The government circulated three Bills in Parliament on April 14, 2026, to enable fresh delimitation, expand the Lok Sabha, and operationalise women's reservation
- The legislative package consists of: (1) Constitution (One Hundred and Thirty-First Amendment) Bill, 2026; (2) Delimitation Bill, 2026; and (3) Union Territories Laws (Amendment) Bill, 2025
- The 131st Amendment Bill proposes expanding Lok Sabha from 543 to 850 members (cap: 815 from States + 35 from Union Territories)
- Delimitation will be based on "such Census as Parliament may by law determine" — effectively the 2011 Census rather than awaiting the 2027 Census
- The Bills amend Article 81 (Lok Sabha composition) and Article 82 (readjustment of constituencies), removing the freeze on seat numbers
- One-third of Lok Sabha and Assembly seats will be reserved for women for 15 years, with rotation after each delimitation cycle

Article 81 and Article 82: Constitutional Framework for Parliamentary Representation
Article 81 of the Constitution specifies the composition of the Lok Sabha, currently capped at 543 elected members from States and up to 2 from Union Territories. The proposed 131st Amendment raises this cap to 850 (815 + 35 UTs). Article 82 mandates readjustment of constituency boundaries after each Census. The 42nd Amendment (1976) and 84th Amendment (2001) froze seat numbers based on the 1971 Census to incentivise states' population control efforts; this freeze expires after the first Census post-2026.
- Current Lok Sabha strength: 543 (democratically elected) + up to 2 Anglo-Indian nominated seats (abolished by 104th Amendment, 2020)
- Proposed strength: 850 (largest democratic chamber in the world by size when implemented)
- The 131st Amendment also amends Articles 170 and 332 (State Assemblies and SC/ST reservation in assemblies)
- The freeze removal changes the marginal heading of Article 82 from "Readjustment after each Census" to "Readjustment of constituencies" — signifying Parliament's discretion over which Census to use
Connection to this news: The 131st Amendment Bill is the central constitutional instrument — UPSC will test its provisions, the Articles it amends, and the policy rationale for seat expansion.
The Delimitation Commission: Composition, Powers, and Finality
The Delimitation Bill, 2026, sets up the Delimitation Commission to redraw constituency boundaries and allocate seats. The Commission is headed by a sitting or retired Supreme Court judge, with the Chief Election Commissioner and State Election Commissioners as members. It is empowered with the powers of a civil court for purposes of inquiry.
- Delimitation Commission's orders have the force of law and cannot be challenged in any court (by constitutional provision)
- The Commission will: allocate seats across states based on updated population data; redraw constituency boundaries; determine SC/ST reserved constituencies; and designate women-reserved constituencies
- Safeguards include: publication of draft proposals, opportunity for objections, and public hearings before finalisation
- Previous Delimitation Commissions: 1952, 1963, 1973, 2002 (for state assemblies only, not Lok Sabha)
Connection to this news: The 2026 Delimitation Commission will be the first to redraw Lok Sabha boundaries since 1976 — a landmark exercise with significant federal and political implications.
North-South Divide: Federalism and Seat Allocation
The most sensitive political dimension of delimitation is the potential shift in parliamentary representation from southern to northern states. Southern states — Andhra Pradesh, Karnataka, Kerala, Tamil Nadu, Telangana — reduced their population growth rates substantially due to successful family planning. Under a pure population-based seat allocation, northern states (UP, Bihar, MP, Rajasthan) — with higher fertility rates — would gain significantly more seats, reducing the relative weight of southern states.
- The 1971 Census freeze was explicitly introduced to prevent penalising states for population control; removing it raises concerns among southern states
- Population projections suggest northern states could gain ~43 seats while southern states lose ~24 under pure population-based reallocation
- The government has promised to maintain states' proportional share of Parliament as it currently stands — placing the burden on the Delimitation Commission to devise a formula
- The capacity of the new Parliament building (~1,224 seats) can accommodate the expanded House of 850
Connection to this news: The North-South divide is a key test of India's cooperative federalism — directly testable in Mains GS2 (federalism, centre-state relations) and Prelims (constitutional facts).
Operationalising Women's Reservation: What Changes
The 2023 Act had linked women's reservation to a post-2023 Census and subsequent delimitation — effectively deferring it to 2034 or later. The 131st Amendment decouples this by allowing delimitation on 2011 Census data. This means: women's reservation can be implemented after the current delimitation exercise concludes, potentially making it operative for the 2029 Lok Sabha election.
- Reservation applies: One-third of Lok Sabha seats, one-third of all State Assembly seats (including within SC/ST quotas)
- Rotation: Reserved constituencies to rotate after each delimitation cycle
- Duration: 15 years (Parliament can extend)
- No OBC sub-quota: Major unresolved political demand
- UT changes: Separate UT Laws Amendment Bill covers Delhi, J&K, and Puducherry
Connection to this news: The sequencing — delimitation first, women's reservation operationalised thereafter — is both a constitutional mechanism and a political signal heading into 2029 elections.
