Delimitation Commissions have been constituted four times in India—in 1952, 1963, 1973, and 2002—under the Delimitation Commission Acts of 1952, 1962, 1972, and 2002.

The Delimitation Commission is a high-power body appointed by the President of India that works in collaboration with the Election Commission of India. Its primary mandate is to redraw the boundaries of the various assembly and Lok Sabha constituencies based on a recent census.

Key features of the Delimitation Commission:

1. Legal Authority: The orders of the Commission have the force of law and cannot be called into question before any court of law.
2. Finality of Orders: When the orders are laid before the Lok Sabha or the State Legislative Assembly, they cannot effect any modifications in the orders.
3. Composition: The Commission consists of three members: a retired judge of the Supreme Court (as Chairperson), the Chief Election Commissioner or an Election Commissioner nominated by them, and the State Election Commissioner of the concerned state.
