What This Article Covers

1.The Constitution (One Hundred And Thirty-First Amendment) Bill, 2026, related to women's reservation and delimitation, was defeated in the Lok Sabha.

2.Article 81's freeze on delimitation, which uses the 1971 Census for inter-state seat distribution, is set to automatically lapse after the 2026 Census data is published.

3.This lapse will enforce the 'one person, one vote, one value' principle, benefiting populous northern states (UP, Bihar) at the expense of southern states (Kerala, Tamil Nadu).

The Big Picture
Prelims · HighMains · High

The delimitation freeze under Article 81 of the Constitution is set to lapse in 2026, requiring a fresh delimitation based on the upcoming Census 2026-27 data. This will significantly alter the Lok Sabha seat distribution among states, shifting political power from southern states to the northern 'Hindi heartland' states, unless the freeze is extended again via a constitutional amendment.
