On 11 March 2026, a two-judge bench held that creamy-layer status under the DoPT 1993 Office Memorandum cannot be determined solely on parental income; the status-based and income-based gates must be applied as distinct, and the DoPT clarificatory letter of 14 October 2004 was held ultra vires the substantive 1993 OM framework.
On 10 April 2008, a five-judge Constitution Bench upheld the Central Educational Institutions (Reservation in Admission) Act 2006 — providing 27% OBC reservation in centrally-funded higher education institutions including the IITs, IIMs, AIIMS and central universities — together with the 93rd Constitutional Amendment that inserted Article 15(5). The Bench extended the Indra Sawhney creamy-layer doctrine to OBC reservation in higher education, preserved the 50% reservation ceiling and required periodic review and quantifiable data. The validity of Article 15(5) for private unaided institutions was left for Pramati (2014) to settle.
On 26 September 2018, a five-judge Constitution Bench held that the creamy-layer principle applies to reservation in promotion for Scheduled Castes and Scheduled Tribes — and read down the requirement, articulated in M. Nagaraj (2006), that States collect quantifiable data to demonstrate backwardness of SC/STs as a condition for providing such reservation. The unanimous judgment of Justice Nariman recalibrates the doctrinal architecture between Indra Sawhney, M. Nagaraj, and the SC/ST promotion reservation regime. A digest of the question, the holding, the doctrinal logic, and the lineage.
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.
On 16 November 1992, a nine-judge Constitution Bench upheld the implementation of the Mandal Commission's recommendation for 27% reservation in Central Government services for Other Backward Classes — but bounded the framework with two structural constraints: reservations could not, in the aggregate, exceed 50% of available positions, and the 'creamy layer' of the backward class had to be excluded from the benefit. Three decades on, the framework remains the constitutional architecture of Indian reservations policy. A digest of the holding, the doctrinal architecture, and how it continues to govern.
