Critically examine the constitutional validity of breaching the 50% reservation ceiling, citing the *Indra Sawhney* judgment and subsequent state exceptions.

The 50% ceiling on reservations is nowhere written into the Constitution; it was judicially crafted in Indra Sawhney v. Union of India (1992) as a facet of the equality guaranteed by Articles 14 and 16(1). Breaching it is therefore constitutionally possible, but only as a narrow, evidence-backed exception.

The ceiling and its in-built exception

• Articles 15(4) and 16(4) are enabling provisions, not mandates. Indra Sawhney upheld the 27% OBC quota, introduced the creamy layer test, and capped total reservation at 50% to balance affirmative action against formal equality [1].
• The same judgment permitted relaxation in "extraordinary situations" — for instance, far-flung populations kept outside the national mainstream [1].

Grounds supporting a breach

• Tamil Nadu's 69% quota (Act 45 of 1994) was placed in the Ninth Schedule under Article 31B and has operated for three decades, showing that a population-proportionate quota can be legislatively sustained [2].
• In Janhit Abhiyan (2022) the Court upheld the 10% EWS quota under the 103rd Amendment, holding that the 50% limit is not inflexible and governs SC/ST/OBC reservations [3].
• Fresh caste enumeration strengthens the empirical case: Karnataka's socio-educational survey has driven demands for reservation of up to 75% for Dalits, backward classes and minorities [4].

Grounds against

• In the Maratha reservation case (2021) the Court struck down the 16% SEBC quota and expressly declined to revisit the ceiling absent extraordinary circumstances [5].
• Ninth Schedule immunity is not absolute after I.R. Coelho (2007); post-1973 entries remain open to basic-structure review.
• Without quantifiable data on backwardness and inadequacy of representation, an excessive quota erodes open competition and administrative efficiency under Article 335, turning the exception into the rule.

The ceiling is thus a rule of judicial prudence rather than an absolute bar. A durable expansion must rest on rigorous commission-backed data — the very purpose of caste enumeration — rather than political assertion. Reliable enumeration, periodic review of backward-class lists under Article 340, and parallel investment in education can reconcile proportional representation with the equality code the Constitution protects.
