Lok Sabha to Expand to 850 Seats: Constitution Amendment Bill to Fast-Track Women's Reservation
The Union Government introduced the Constitution (131st Amendment) Bill, 2026, proposing to expand the Lok Sabha from 543 to a maximum of 850 seats (815 from States, 35 from Union Territories)
The Bill amends Article 81 (composition of Lok Sabha), Article 82 (delimitation after census), and Article 334A (women's reservation implementation trigger)
By removing the current requirement that delimitation must use data from the "first census after 2026," the Bill allows delimitation to proceed using 2011 Census data immediately
The move is designed to implement the 33% women's reservation (Nari Shakti Vandan Adhiniyam, 2023) before the 2029 Lok Sabha elections without waiting for the next census cycle
The Bill was circulated among MPs for introduction in a Special Session of Parliament on April 16–17, 2026
Article 81: Composition of the House of the People
Article 81 of the Constitution lays down the composition of the Lok Sabha. Currently, it provides for not more than 530 members chosen by direct election from States and not more than 20 representing Union Territories — a maximum of 550. The current effective strength is 543 (530 States + 13 UTs). The proposed 131st Amendment seeks to revise these ceilings to 815 (States) + 35 (UTs) = 850.
The Bill amends Article 81 to create the constitutional space for 307 new seats, paving the way for expanded representation while accommodating the women's reservation mandate.
Article 82: Delimitation After Each Census (and the Freeze History)
Article 82 requires Parliament to enact a law for readjusting Lok Sabha seat allocation after every census. The 42nd Amendment Act (1976) froze seat allocation based on the 1971 Census to prevent States with higher population growth from gaining disproportionate seats. The 84th Amendment Act (2001) extended this freeze until the first census after 2026; the 87th Amendment Act (2003) allowed constituency boundary readjustment (not seat reallocation) using 2001 Census data. The current Bill removes the proviso requiring post-2026 Census for the next delimitation.
Deleting the third proviso of Article 82 is the key constitutional move that allows delimitation — and therefore women's reservation — to proceed before 2026 census data is available.
Article 334A: Women's Reservation Implementation Trigger
Article 334A was inserted by the 106th Constitutional Amendment Act, 2023 (Nari Shakti Vandan Adhiniyam). It mandates that women's reservation (one-third of seats in Lok Sabha and State Assemblies) shall come into effect only after (a) the first census conducted after the Act's commencement is published, AND (b) a delimitation exercise based on that census is completed. The proposed Bill amends Article 334A to delink the census requirement, allowing women's reservation to take effect after the upcoming delimitation using 2011 Census data.
Amending Article 334A removes the census-first bottleneck, enabling women's reservation to be operationalised immediately after the new delimitation based on 2011 data — potentially in time for 2029 general elections.
