What Happened
- During a Parliament special session on April 16, 2026, the Home Minister rebutted claims that southern states would see reduced representation following Lok Sabha expansion to 816 seats.
- He stated that the total Lok Sabha strength would rise to 816 elected seats (ceiling: 850), representing a precise 50% increase over 543 seats, and that each state would receive a proportional 50% uplift.
- He argued that southern states' share would stay essentially constant — rising from 129 seats to 195 seats (23.76% → ~23.87%), and that characterising this as a "weakening" was a false narrative.
- The bills introduced include the Constitution (131st Amendment) Bill, 2026, the Delimitation Bill, 2026, and the Union Territories Laws (Amendment) Bill, 2026.
- Opposition parties contested that while absolute seat numbers increase, the permanent proportionate share disadvantage stemming from the choice of the 2011 Census (rather than a fresh census) is the real issue.
Static Topic Bridges
Article 81 and the Population-Representation Formula
Article 81(2) of the Constitution sets the rule that the number of Lok Sabha seats for a state shall be determined so that the ratio between that number and the state's population is as nearly equal as practicable. This direct population-seat ratio linkage is the root of the North-South tension.
- The 42nd Amendment (1976) inserted the instruction to use the 1971 Census figures for allocation of seats to states, decoupling seat counts from subsequent census population data.
- The 84th Amendment (2001) extended this freeze until after the first census taken after 2026, preventing reallocation for another 25 years.
- The 131st Amendment Bill, 2026, proposes to remove the post-2026-census condition and permit delimitation using the 2011 Census immediately.
Connection to this news: The government's claim of a "50% uniform increase" is accurate only as an absolute gain; the proportionate share question depends entirely on which census is used as the denominator — the 2011 Census would still reflect the differential fertility trajectories of North and South since 1971.
Basic Structure Doctrine and Federalism: Kesavananda Bharati v. State of Kerala (1973)
The Supreme Court's landmark ruling in Kesavananda Bharati (1973) held that Parliament's power to amend the Constitution under Article 368 cannot be used to destroy its "Basic Structure". While the Court has not explicitly listed all elements of Basic Structure, federalism and the democratic principle of equal representation have been considered part of it by various subsequent benches.
- Article 368 allows Parliament to amend the Constitution by a two-thirds majority of members present and voting, plus a majority of total membership.
- Amendments that affect the federal character — such as altering states' relative share of political power — could theoretically be challenged under the Basic Structure doctrine.
- However, delimitation orders themselves are insulated from judicial review under Article 329(a), creating a tension between the open-ended Kesavananda principle and the parliamentary finality over delimitation.
- The 131st Amendment Bill is a Constitution amendment bill (requiring Article 368 special majority) as distinct from the Delimitation Bill, 2026 (an ordinary parliamentary law).
Connection to this news: Opposition arguments that the delimitation proposal is an "attack on democracy" or on federalism are implicitly invoking the Basic Structure doctrine — asserting that permanently reducing southern states' proportionate weight in Parliament alters the fundamental federal compact.
Types of Majorities in Parliament: Article 368 vs. Simple Majority
Not all parliamentary decisions require the same threshold. The distinction is critical to understanding both the delimitation and women's reservation bills.
- Simple majority: More than 50% of members present and voting — used for ordinary legislation.
- Special majority (Article 368): Two-thirds of members present and voting AND majority of total membership of each House — required for constitutional amendments.
- Ratification by states (Article 368 proviso): Some amendments additionally require ratification by at least half the state legislatures — specifically those affecting federal provisions like Articles 54, 55, 73, 162, 241, or Chapter IV of Part V/Part VI/Part XI.
- The Lok Sabha expansion (131st Amendment) and the Women's Reservation implementation both require the Article 368 special majority.
Connection to this news: The government holds ~293 of 543 seats in the Lok Sabha (~54%), well short of the two-thirds threshold (~362 for a full House), making cross-party support essential for passing constitution amendment bills.
