What Happened
- The Union Government circulated copies of three Bills to MPs ahead of the Special Parliament Session on April 16–17, 2026: (1) Constitution (131st Amendment) Bill, 2026; (2) Delimitation Bill, 2026; (3) a Bill enabling women's reservation in Union Territories
- The Constitution Amendment Bill amends Articles 81, 82, and 334A to expand Lok Sabha to 850 seats and delink women's reservation from the post-2026 census requirement
- A key feature is the "proportional freeze" mechanism — seats for each State are allocated in proportion to current population but no State shall lose seats it currently holds in absolute terms
- The Bills were described by critics as circulated in an "opaque and non-consultative" manner; opposition parties held a press conference on the method of introduction
- The Delimitation Bill establishes a new Delimitation Commission and defines its process; orders of the Commission are to have the force of law and cannot be challenged in courts

Proportional Freeze Mechanism — Addressing the North-South Divide
The "proportional freeze" is a proposed safeguard under the Bills that prevents any State from losing the absolute number of Lok Sabha seats it currently holds. Under pure population-proportional delimitation using 2011 Census data, States with higher fertility (largely northern) would gain significantly while States with lower fertility (largely southern) would proportionally shrink. The "grow the pie" model — expanding total seats from 543 to 850 — combined with a floor that guarantees no State loses existing seats attempts to address this tension. States get new seats distributed in proportion to population growth, but the existing 543 seats are "frozen" for their current holders.
- Current Lok Sabha strength: 543 seats
- Proposed maximum: 850 seats (307 new seats to be distributed)
- Southern States' concern: Even with 850 seats, proportion of southern seats in total Lok Sabha would decline
- Mathematical implication: If UP currently has 80 seats (14.7%), a population-proportional 850-seat house could give it 130+ seats; Tamil Nadu currently has 39 seats, might retain 39 but drop from 7.2% to ~4.6%
- "Proportional freeze" approach: Fix current proportional shares OR guarantee absolute floor of current seats
Connection to this news: The proportional freeze mechanism is the government's attempt to resolve the constitutional equity tension — rewarding population-growth States while not penalising population-controlled States — at the heart of opposition to these Bills.
"Latest Census" Flexibility — Removing the Post-2026 Lock
The existing third proviso to Article 82 mandates that the next delimitation exercise shall use data from the "first Census conducted after the year 2026." The Bills propose to delete this proviso entirely, replacing it with language allowing Parliament to specify which census data to use. This grants Parliament — rather than the Constitution — the discretion to decide the population baseline for delimitation. The Bills intend to use 2011 Census data (the most recent available) for the immediate delimitation, enabling women's reservation to be implemented for 2029 elections.
- Current proviso: Delimitation must use "first census after 2026" (i.e., ~2027–2028 census + publication delays)
- Under existing law, post-2026 census data would not be available before 2031 at the earliest, making 2029 implementation impossible
- Proposed change: Parliament decides which census to use (giving legislative flexibility over constitutional mandate)
- 2011 Census data: Last available; 2021 Census delayed due to COVID-19, not yet conducted as of 2026
Connection to this news: The deletion of the post-2026 census requirement is the critical enabling provision that makes 2029 implementation of women's reservation legally possible.
Delimitation Bill 2026 — Commission Structure and Legal Force
The accompanying Delimitation Bill, 2026 creates the statutory framework for the new delimitation exercise. Key features include a Delimitation Commission chaired by a sitting or former Supreme Court judge (ensuring judicial credibility), with election officials and State-level associate members. Crucially, the Commission's final orders will have the force of law and cannot be challenged in any court — following precedent established in earlier delimitation Acts and reinforced by Article 329 of the Constitution.
- Delimitation Commission chair: Sitting or former Supreme Court judge
- Ex-officio members: Chief Election Commissioner (or nominated Election Commissioner) + State Election Commissioner
- Associate members per State: 10 (5 MPs + 5 MLAs, non-voting)
- Legal force of orders: Cannot be challenged in court (Article 329 bar on judicial review of delimitation)
- Previous Delimitation Acts: 1952, 1962, 1972, 2002
- 2002 Commission chair: Justice Kuldip Singh (retired Supreme Court judge)
Connection to this news: The Delimitation Bill creates the institutional machinery that will implement the constitutional changes — defining how the 307 new seats are allocated and boundaries redrawn across States and Union Territories.
