What Happened
- The Union Government circulated the draft Constitution (131st Amendment) Bill, 2026, which proposes increasing the strength of the Lok Sabha from the existing 543 seats to a maximum of 850 seats.
- Of the proposed 850 seats, 815 will be allocated to States and 35 to Union Territories — amending Article 81 of the Constitution.
- The Bill proposes to delete the third proviso to Article 82, which currently mandates that the next delimitation shall be based on the first census conducted after 2026.
- Instead, the Bill allows Parliament (by simple majority) to decide which census will form the basis of delimitation — with the 2011 Census data proposed as the immediate operative dataset.
- The Bill simultaneously amends Article 334A to allow the one-third women's reservation (enacted under the Nari Shakti Vandan Adhiniyam, 2023) to take effect immediately after delimitation, targeting the 2029 Lok Sabha elections.
- A special Parliamentary session was scheduled for April 16-18, 2026, to take up both the 131st Amendment Bill and the companion Delimitation Bill, 2026.

Constitutional Provisions Governing Lok Sabha Composition
Article 81 of the Constitution specifies that the House of the People shall consist of not more than 550 members directly elected from States and Union Territories. The current ceiling (post-84th Amendment) is 543 elected members plus 2 nominated Anglo-Indian members (later removed by the 104th Amendment). The 131st Amendment Bill proposes to raise this ceiling to 850, representing the most significant expansion of the lower house since independence.
- Article 81(2): The allocation of seats to each State is based on population (1971 Census for current Lok Sabha, frozen till post-2026 Census by the 42nd Amendment as extended by the 84th and 87th Amendments).
- Article 82: After every census, Parliament by law readjusts the allocation of seats in Lok Sabha and the division of each State into territorial constituencies (delimitation).
- The 42nd Amendment (1976) froze delimitation based on 1971 Census until after the 2000 Census; the 84th Amendment (2001) extended the freeze till after the 2026 Census.
- The proposed 131st Amendment deletes this freeze and substitutes Parliament's discretion — allowing delimitation based on 2011 Census data before the 2027 Census is complete.
Connection to this news: The 131st Amendment is designed to break the constitutional deadlock that would otherwise delay women's reservation till ~2034, by enabling delimitation based on 2011 data and allowing the Nari Shakti Vandan Adhiniyam to take effect from 2029.
Delimitation: Process and Constitutional Framework
Delimitation is the process of redrawing the boundaries of parliamentary and assembly constituencies to reflect population changes. It is carried out by a Delimitation Commission — a statutory body constituted under the Delimitation Act, 2002. The Commission's orders have the force of law and cannot be challenged in any court (Article 329). Previous Delimitation Commissions: 1952, 1963, 1973, 2002. Each was followed by the corresponding Lok Sabha elections.
- Delimitation Commission: Chairperson is a retired Supreme Court judge; members include the Chief Election Commissioner and State Election Commissioners.
- The 2002 Commission (reporting 2007) redrew constituencies based on the 2001 Census.
- Delimitation adjusts SC/ST reserved seats in proportion to their population in each constituency.
- The Delimitation Bill, 2026, proposes to set up a new Delimitation Commission using 2011 Census population data to redraw all 850 Lok Sabha and corresponding assembly constituencies.
Connection to this news: Using the 2011 Census (15 years old) for delimitation is central to the political controversy — southern states that implemented population control policies fear losing seats relative to high-population northern states.
Women's Reservation: Legislative History and Article 334A
The demand for women's reservation in Parliament has been pending since 1996, when the Constitution (81st Amendment) Bill was first introduced. After multiple failed attempts (1998, 1999, 2008, 2010 — the Rajya Sabha passed it in 2010, but it lapsed without Lok Sabha passage), the 128th Constitution Amendment Bill was finally passed as the Nari Shakti Vandan Adhiniyam (Constitution 106th Amendment Act) in September 2023. It inserted Article 330A (Lok Sabha) and Article 332A (State Assemblies) reserving one-third of seats for women, including SC/ST women. However, the original Act tied implementation to post-census delimitation, effectively deferring it to ~2034.
- Article 334A (original): Women's reservation operative "after the census taken after the commencement of the Constitution (One Hundred and Sixth Amendment) Act, 2023."
- The 131st Amendment proposes to amend Article 334A to remove this census precondition and link women's reservation to the new delimitation exercise.
- If 850 seats are created and 1/3rd reserved for women: approximately 283 seats reserved for women.
- Women currently constitute only ~15% of Lok Sabha members (82 out of 543 after 2024 elections).
Connection to this news: The 131st Amendment cleverly bundles the expansionary political benefit (more seats for all states) with the women's reservation promise, using the former as a sweetener to secure opposition support for the latter.
