Delimitation Current Affairs for UPSC

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.

The Constitution (131st Amendment) Bill, 2026 failed to pass in the Lok Sabha because it did not receive the special majority required under Article 368 of the Constitution. The bill sought to enable fresh delimitation, increase Lok Sabha strength to 850 seats and operationalise one-third women’s reservation. This article explains the constitutional amendment procedure, special majority requirement, technical provisions of the bill, delimitation framework and all basic constitutional concepts behind why such a bill can fail in Parliament.
