Delimitation Bill 2026: Introduced in Lok Sabha, Constitution Amendment Bill Voted Down

Delimitation Bill, 2026 was introduced in Lok Sabha on April 16, 2026, as part of a three-bill package aimed at increasing the number of parliamentary seats and making women's reservation a reality from the 2029 elections. However, the constitutional amendment Bill that was needed to put this plan into action was voted down on April 17, 2026, and the government subsequently withdrew the Delimitation Bill. This is the first time a constitutional amendment brought by the Modi government has failed in the Lok Sabha.

The three Bills introduced were: (i) the Constitution (131st Amendment) Bill, 2026, (ii) the Union Territories Laws (Amendment) Bill, 2026, and (iii) the Delimitation Bill, 2026 (Bill No. 108 of 2026). Together, they proposed to expand Lok Sabha from 543 to 850 seats, base delimitation on the 2011 Census, and activate 33% women's reservation through the Nari Shakti Vandan Adhiniyam that had received Presidential assent in 2023.

What Happened on April 17 in Lok Sabha

During the vote on the Constitution (131st Amendment) Bill, 2026, a total of 528 MPs were present. The Bill received 298 votes in favour and 230 votes against. Since a constitutional amendment requires a two-thirds majority of members present and voting, the government needed 352 votes but fell short by 54. The Bill was negatived, making it impossible to proceed with the Delimitation Bill or the Union Territories Laws (Amendment) Bill, both of which depended on the constitutional amendment passing first.

Home Minister Amit Shah, while speaking in the Lok Sabha, said that the opposition was misleading the country and that the southern states would actually gain seats, not lose them. He stated that southern states currently hold 129 seats (about 23.76% of the House), and after the proposed 50% expansion their count would rise to 195 seats, still roughly 24% of the 816-seat expanded House. Kerala's seats, for example, would rise from 20 to 30. The opposition rejected these arguments.

Why Opposition Opposed the Bills

Opposition parties, particularly those from southern and north-eastern states, opposed the bills on two main grounds. First, they argued that basing delimitation on the 2011 Census would reduce the proportional representation of states that had better controlled their population growth, primarily the five southern states. Congress leader P Chidambaram estimated that if seats were redistributed on current population, southern states would go from 129 seats down to 103, losing 26 seats, while large-population northern states like Uttar Pradesh and Bihar would gain heavily.

Second, the opposition questioned why the government was rushing delimitation when the 2026-27 Census is already underway. They also argued that the constitutional amendment, while wrapped around women's reservation, would actually dilute southern states' political voice in Parliament.

Key Proposals in Delimitation Bill 2026

Although the bills did not pass, understanding their key proposals is useful since the government may bring a revised version in future sessions.

• Lok Sabha seats to increase from 543 to 850, with up to 815 from states and up to 35 from union territories. Current cap is 550 members.
• 2011 Census to be used as the basis for delimitation. Parliament would have the power to decide which census and when to use it for future exercises.
• Delimitation Commission to be formed by the central government. It would include a retired Supreme Court judge as Chairperson, the Chief Election Commissioner, and the State Election Commissioner of each state. Five Lok Sabha MPs and five State Assembly members from each state would serve as associate members without voting rights.
• Women's reservation to be linked to delimitation. The 106th Constitutional Amendment (2023) is now notified and in force from April 16, 2026. The 2026 bills sought to activate its provisions by tying it to the new delimitation rather than waiting for the post-2027 Census.

Background: Why Delimitation Has Been Frozen

India has not carried out a fresh delimitation of parliamentary seats since 1973, when boundaries were redrawn based on the 1971 Census. In 1976, the 42nd Constitutional Amendment froze the number of seats each state holds in Lok Sabha until the publication of the first census after 2000. The 84th Constitutional Amendment in 2001 further extended this freeze until the publication of the first census after 2026. This freeze was put in place to make sure states with better family planning programmes were not penalised by losing parliamentary seats.

The last Delimitation Commission was formed in 2002 and finalised its orders in 2008. That exercise only redrawn constituency boundaries within states; it did not change the number of seats each state gets. The upcoming exercise, if eventually carried out, will be the first in over 50 years to change the seat allocation between states.

Women's Reservation Status After the Vote

Even though the constitutional amendment failed, the 106th Constitutional Amendment Act (Nari Shakti Vandan Adhiniyam, 2023) is now officially in force from April 16, 2026, after the Union Government issued a notification under Section 1(2) of the Act. However, under the original 2023 law, women's reservation cannot actually be applied to elections until after the completion of a delimitation exercise based on the first census after the Act's commencement. Since the 2026 bills failed, the trigger for that delimitation is still tied to the post-2027 Census. This means women's reservation is unlikely to apply to the 2029 Lok Sabha elections.
