Discuss the evolution of the 'creamy layer' concept in OBC reservations in India. Examine the implications of recent judicial pronouncements on its determination.

Reservation under Article 16(4) is a tool of substantive equality, not a hereditary entitlement. The 'creamy layer' filter — excluding socially advanced sections among OBCs — was judicially engrafted to keep benefits flowing to the genuinely backward, and its correct test is again before the Supreme Court.

Evolution of the concept

• Indra Sawhney v. Union of India (1992): a nine-judge Bench upheld 27% OBC reservation but made exclusion of the creamy layer a constitutional imperative [1].
• DoPT Office Memorandum of 8 September 1993 operationalised it through a status-based test — the category of post held by parents (Group A/B), constitutional office, profession and landholding — with income as a supplementary indicator [2].
• 2004 DoPT clarification extended the test to PSU and private-sector employees, effectively converting parental salary into the decisive yardstick, while the income ceiling was periodically revised.

Recent judicial pronouncement and its determination test

• In Union of India v. Rohith Nathan (11 March 2026), the Court held that the 2004 letter cannot override the 1993 OM; salary alone cannot establish creamy-layer status, and the nature and status of the post must be examined [3].
• It directed supernumerary posts for OBC candidates excluded solely on parental salary [3].

Implications

• Social justice: restores the original occupational-status logic and remedies the exclusion of genuinely backward candidates.
• Administrative: retrospective reach unsettles appointments and seniority finalised over more than a decade, prompting the Centre's plea and the possible constitution of a special Bench, with the service allocation of 958 CSE-2025 candidates in the balance [4].
• Policy: underlines the pending task of framing credible post-equivalence norms for private-sector employment.

The controversy shows that social justice and administrative certainty are complementary, not competing, goals. Updating the 1993 framework with transparent equivalence rules, and applying corrections prospectively wherever feasible, would secure both — keeping reservation faithful to the constitutional promise of equality of opportunity.
