What Happened
- The Constitution (131st Amendment) Bill, 2026 was put to a vote in Lok Sabha on April 17, 2026, after a 21-hour debate spanning two days.
- The bill received 298 votes in favour and 230 votes against — a total of 528 MPs voted.
- To pass, a constitutional amendment requires a special majority: a majority of the total membership of the House (272 of 543) AND at least 2/3rd of members present and voting (352 of 528 = ~352 votes). The bill fell short by 54 votes.
- This became the NDA government's first legislative defeat since 2014, marking a significant political moment.
- Following the bill's defeat, Union Minister Kiren Rijiju withdrew two linked bills — the Delimitation Bill, 2026 and the Union Territories Laws (Amendment) Bill, 2026.
- The bill had proposed increasing Lok Sabha seats from 543 to 850 and linking the implementation of women's 33% reservation (already enacted via the 106th Amendment in 2023) to a fresh delimitation exercise.
Static Topic Bridges
Constitutional Amendment Procedure — Article 368
Article 368 vests Parliament with the power to amend the Constitution. It lays out three tiers of amendment: (1) by simple majority (not covered under Article 368 — e.g., creation of new states under Article 3); (2) by special majority — majority of total membership of each House AND 2/3rd of members present and voting; (3) by special majority PLUS ratification by at least half the state legislatures (for federal provisions).
- Article 368(2): Bill must be passed by each House by a majority of the total membership of that House AND by a majority of not less than 2/3rds of the members of that House present and voting
- "Total membership" majority = more than 50% of 543 = at least 272 in Lok Sabha
- "2/3rd present and voting" majority: if 528 voted, 2/3rd of 528 = 352 votes required
- Landmark case: Kesavananda Bharati v. State of Kerala (1973) — established that Parliament cannot use Article 368 to alter the "basic structure" of the Constitution
- Difference from "absolute majority": an absolute majority is a majority of the total membership (regardless of those present), while the Article 368 special majority combines both a total membership threshold AND a threshold of those present and voting
Connection to this news: The bill secured 298 yes votes against a requirement of 352 (2/3rd of 528 present and voting), falling short by 54 votes. The dual threshold nature of Article 368 makes constitutional amendments deliberately difficult, requiring broad consensus — which the government could not secure given strong opposition.
NDA's Coalition Arithmetic and Legislative Defeats
The NDA controls a majority in Lok Sabha but not the enhanced two-thirds majority required under Article 368. With 543 seats total, the NDA's seat tally of approximately 293 seats (after 2024 elections) means it must rely on cross-party support for constitutional amendments. This structural constraint is why constitutional amendments are rare even for governments with comfortable majorities.
- NDA won approximately 293 seats in the 2024 Lok Sabha elections, short of a special majority
- 272 seats = simple majority threshold in Lok Sabha
- 362 seats = 2/3rd of total membership (the higher threshold sometimes cited; the actual requirement is 2/3rd of members present and voting)
- Previous constitutional amendments under NDA: 99th (NJAC), 100th (Land Boundary Agreement), 101st (GST), 102nd (OBC list), 103rd (EWS), 104th (SC/ST reservation extension), 106th (Women's Reservation) — all passed with opposition support or during periods of numerical dominance
Connection to this news: The bill's defeat signals the limits of coalition governance when constitutional changes require supermajorities. The opposition's near-unified front on the delimitation linkage proved decisive.
