Delimitation

Constitutional Basis and Process

Delimitation is the process of fixing the number of seats in the Lok Sabha and State Legislative Assemblies and redrawing the boundaries of parliamentary and assembly constituencies. It is constitutionally mandated by Article 82 (parliamentary seats) and Article 170 (state assembly seats), which require readjustment after every Census. A Delimitation Commission is constituted under the Delimitation Act for this purpose. The Commission is headed by a retired or sitting Supreme Court judge and includes the Chief Election Commissioner and the concerned State Election Commissioners as ex-officio members. Associate members (MPs and MLAs) may participate in an advisory capacity without voting rights. Critically, the orders of the Delimitation Commission are final and cannot be challenged in any court of law — they are published in the Gazette of India and are binding for the next elections.
