The Supreme Court will hear the Centre's plea seeking clarification of its earlier ruling that a parent's salary alone cannot determine whether an OBC candidate falls within the creamy layer. The original judgment held that overall economic and social advancement must be assessed holistically, not by income alone. The Centre now seeks guidance on how to operationalise this principle while framing OBC reservation policy, making this a pivotal moment for reservation jurisprudence under Articles 15 and 16.

The 'creamy layer' doctrine is a constitutional device originating in Indra Sawhney v. Union of India (1992), where a nine-judge bench held that the most advanced members of OBCs — those who have already achieved social and educational advancement comparable to the forward classes — must be excluded from OBC reservations. The court reasoned that reservation under Articles 15(4) and 16(4) targets backwardness, and once that backwardness is overcome, the constitutional justification for special treatment disappears.

The creamy layer test is therefore not merely an income test; it is a composite test of social, educational, and economic advancement. The Supreme Court's ruling under challenge clarified this: salary of a parent, taken in isolation, cannot be the sole criterion. A government employee earning above a threshold but belonging to a community still socially backward may not automatically cross the creamy layer.

This matters for Article 16(4), which permits the state to make provisions for reservation of appointments or posts in favour of 'backward class of citizens' that is 'not adequately represented.' The creamy layer exclusion ensures that 'backward class' is defined with precision — capturing genuine backwardness, not historical caste identity alone.

The Centre's plea now asks the court to translate this principle into an administrable standard — which criteria beyond income (parental occupation, generation of education, social mobility indicators) must be factored in. The answer will directly govern how Union Public Service Commission and state service commissions classify OBC candidates at the certificate-verification stage.
