Article 82 (Parliament) and Article 170 (State Assemblies): Delimitation of constituencies based on latest census figures. However, 42nd Amendment (1976) froze delimitation based on 1971 census till 2001; 84th Amendment (2001) extended freeze till first census after 2026. Aims to encourage population control measures without penalizing States that control population growth.
