What Happened
- Following the defeat of the Constitution (131st Amendment) Bill, 2026 in the Lok Sabha on April 17, 2026, opposition leaders including Congress MP Priyanka Gandhi Vadra and SP leader Dimple Yadav clarified that they support women's political reservation but opposed the government's approach of linking it to delimitation using the 2011 census.
- Priyanka Gandhi called the bill's defeat a "win for democracy" and alleged it was a "conspiracy" by the government to use women's reservation as a "decoy" to push through a delimitation exercise that would permanently alter the federal balance of seats in Parliament in favour of northern states.
- Opposition demanded immediate implementation of the existing 106th Constitutional Amendment Act (Nari Shakti Vandan Adhiniyam, 2023) which already provides 33% reservation for women — without any fresh delimitation or census precondition.
- The 131st Amendment Bill had sought to: (a) expand Lok Sabha seats from 550 to 850; (b) allow delimitation based on the 2011 census; (c) remove the post-census, post-delimitation trigger that had frozen the 2023 Act's implementation.
- Congress leader Priyanka Gandhi also demanded that before any delimitation, caste enumeration must be completed so that OBC communities get proportional representation within the reserved seats.

106th Constitutional Amendment Act, 2023 — Nari Shakti Vandan Adhiniyam
The 106th Constitutional Amendment Act, 2023, commonly called the Nari Shakti Vandan Adhiniyam, provides one-third (33%) reservation for women in the Lok Sabha, State Legislative Assemblies, and the legislative assembly of the National Capital Territory of Delhi. The reservation is to be allocated by rotation among constituencies by the delimitation authority. Crucially, the Act contains a "trigger clause" — Article 334A(2) specifies that the reservation shall come into effect only after the first census conducted after the commencement of this Act and after the subsequent delimitation based on that census. This trigger has been the central controversy.
- Inserted Articles 330A (reservation in Lok Sabha), 332A (reservation in state assemblies), and 334A (commencement clause — triggered by post-Act census + delimitation)
- Reservation includes sub-reservation for SC/ST women within the reserved pool
- Duration: 15 years from commencement (Article 334A(3))
- Passed by Rajya Sabha on September 21, 2023 and Lok Sabha on September 20, 2023; received Presidential assent on September 28, 2023
- The "trigger clause" (Article 334A(2)) means that without census and delimitation, the 2023 Act cannot be operationalised — which is what the 131st Amendment sought to unlock
Connection to this news: The opposition's demand — "implement the 2023 Act immediately" — is constitutionally impossible without amending or removing Article 334A(2), since the Act is self-frozen until post-census delimitation. The 131st Amendment sought to do exactly this (remove the census trigger), but linked it to a 2011-census-based delimitation that the opposition found unacceptable.
Constitutional Amendment Procedure — Article 368
Article 368 governs the procedure for amending the Constitution. Amendments related to the federal structure require ratification by at least half the state legislatures in addition to a "special majority" in Parliament. A special majority means: (a) a majority of the total membership of each House, and (b) a majority of not less than two-thirds of the members of each House present and voting. The 131st Amendment Bill failed because it secured 298 votes in favour against 230 against, with 528 members present and voting — requiring 352 (two-thirds of 528) to pass, but only getting 298 (56.4%), falling 54 votes short.
- Article 368(2): Standard constitutional amendment requires special majority (absolute majority + two-thirds of those present and voting)
- Article 368(2) proviso: Certain provisions (federal structure, election of President, SC/HC jurisdiction, distribution of legislative powers) additionally require ratification by half the state legislatures
- Simple majority: more than half of members present and voting (for ordinary laws)
- Effective/absolute majority: more than half of total House membership (e.g., no-confidence motion)
- Bills under Schedule 5 and 6, Articles 54, 55, 73, 162, Part V Chapter IV, Part VI Chapter V, Part XI, or lists in Schedule 7 require state ratification
Connection to this news: The 131st Amendment's defeat illustrates the high threshold for constitutional change — the government needed two-thirds of those present, not just a simple majority. The distinction between types of parliamentary majorities is a recurring UPSC topic.
Delimitation — Constitutional Basis and Federal Concerns
Delimitation is the process of redrawing boundaries of parliamentary and assembly constituencies and reallocating seats among states in proportion to their population. Article 82 mandates readjustment of Lok Sabha seats after each census. Article 170 similarly applies to state assemblies. A Delimitation Commission — a statutory body under the Delimitation Commission Act — conducts the exercise. The last delimitation was done in 2002 (based on 1991 census); seats have been frozen since then under the 42nd Amendment (1976), extended by the 84th Amendment (2001) until after the 2026 census. The 131st Amendment proposed to conduct delimitation based on the 2011 census instead of waiting.
- Article 82: After each census, Parliament by law readjusts representation of states in Lok Sabha (Delimitation Act)
- Article 55(3): Proportional representation among states for presidential election — linked to Lok Sabha seats
- 42nd Constitutional Amendment (1976): Froze seats until 2000 (later extended by 84th Amendment to after 2026 census)
- Southern states' concern: States that successfully controlled population growth (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh) fear losing Lok Sabha seats under population-based delimitation to more populous northern states
Connection to this news: The southern states' anxiety about delimitation — losing seats after decades of effective population control — was the driving force behind the opposition to the 131st Amendment Bill. This tension between population-based proportional representation and equitable federal representation is a core challenge in India's federal design.
