Retrospective application of judicial rulings often creates administrative complications in service matters. Discuss with reference to the OBC creamy-layer controversy.

Judicial rulings ordinarily operate retrospectively, declaring what the law always was. The Supreme Court's decision in Union of India v. Rohith Nathan (11 March 2026) on OBC creamy-layer determination [1] shows how this can unsettle concluded service matters even while correcting genuine injustice.

The ruling and its retrospective reach

• The Court held that a parent's salary alone — in a PSU or private firm — cannot decide creamy-layer status; the nature and category of the post must be examined, so the 1993 Office Memorandum prevails over the later income-based clarification [1][3].
• It directed creation of supernumerary posts for OBC candidates excluded solely on parental salary [1].
• The Centre submits that this logic reaches service matters settled since 2012 [2].

Resulting administrative complications

• Ongoing allocation stalled: DoPT sought leave to allot services to the 958 CSE-2025 recommendees on pre-verdict criteria; the Court is weighing a special Bench [2].
• Seniority churn: reopening past selections would drastically alter cadre seniority, with a cascading effect even on Unreserved candidates [2].
• Surge of fresh claims from aspirants who never sought non-creamy-layer certification earlier [2].
• Verification burden: post-equivalence between PSU/bank and government posts must be settled case by case [4], straining the certification machinery under the reservation framework [6].

The competing demand of justice

• Excluding genuinely backward candidates on income alone amounts to hostile discrimination, defeating the purpose of Article 16(4) [1].
• Since Indra Sawhney, correct identification of the creamy layer is a constitutional obligation, not a matter of administrative convenience [5].

The dispute is therefore less about the correctness of the interpretation than about its temporal reach. A calibrated use of prospective overruling — protecting concluded appointments while granting relief to identified claimants through supernumerary posts — can reconcile the two. Codifying clear post-equivalence norms would let administrative stability and substantive equality advance together.
