On 1 August 2024, a seven-judge Constitution Bench held by 6:1 that sub-classification within Scheduled Castes for reservation purposes is constitutionally permissible — and overruled E.V. Chinnaiah v. State of Andhra Pradesh (2004), which had held that the Scheduled Castes constituted a homogeneous class. The judgment recalibrates the Indra Sawhney – M. Nagaraj – Jarnail Singh line on reservation and opens the door to sub-quotas within SC reservation for the most disadvantaged sub-groups, subject to empirical data and constitutional safeguards. A digest of the bench, the opinions, the overruling of E.V. Chinnaiah, and what States can now do.
