The Union government is preparing to reintroduce its constitutional amendment for delimitation and women's reservation, two months after the Constitution (131st Amendment) Bill, 2026 was defeated in the Lok Sabha in April for want of a two-thirds majority. The reworked plan reportedly seeks to add clarity that every state's existing seat share will be protected even as the House is expanded to around 850 seats, with allocation among states kept proportionate to the 1971 Census — a move aimed at winning over southern states and the DMK. This article explains what delimitation is, the constitutional provisions (Articles 81, 82, 170, 330, 332), the 1971 Census "freeze", the women's reservation link, the North-South federalism debate, and why a Constitution Amendment Bill can fail despite a clear majority.
