Delimitation of constituencies and determination of constituencies reserved for SCs and STs are done

The delimitation of constituencies and the determination of seats reserved for Scheduled Castes (SCs) and Scheduled Tribes (STs) are primarily the responsibility of the Delimitation Commission [3]. Under Article 82 of the Constitution, Parliament enacts a Delimitation Act after every census to establish this independent, high-powered body [3]. The Commission is appointed by the President of India and works in collaboration with the Election Commission of India, with the Chief Election Commissioner serving as an ex-officio member [3]. Its mandate includes redrawing electoral boundaries and fixing the quota of reserved constituencies based on the proportion of SC or ST populations in each state [3]. The decisions of the Delimitation Commission have the force of law and cannot be challenged in any court, ensuring the stability of the electoral process [3].
