Should reservation for SCs and STs be proportional to their population even when this exceeds the 50% ceiling? Critically analyse.

Articles 15(4) and 16(4) allow reservation for SCs and STs so that they have adequate representation. Indra Sawhney (1992) capped total reservation at 50%, with an exception only for "extraordinary circumstances" [3]. Karnataka's 2022 hike (SC 15%→17%, ST 3%→7%, total 56%) was struck down as "constitutionally impermissible" [1]. The case tests whether population share alone should override the cap.

Case for population-proportional quotas

• Substantive equality: SCs and STs face exclusion based on caste and tribe, not just backwardness. Population share is the natural measure, and Karnataka's hike followed the Nagamohan Das Commission's recommendation [1].
• Cap is judge-made, not textual: In Janhit Abhiyan (2022), the majority said the 50% limit is not inflexible and upheld 10% EWS reservation above it [5].
• Inconsistency: Allowing EWS above 50% while refusing a few points to the most disadvantaged groups looks unequal.
• Precedent: Tamil Nadu's 69% quota has survived through Ninth Schedule protection (76th Amendment).

Case against / limitations

• Equal opportunity: Article 16(1) and Article 335 (efficiency of administration) treat reservation as an exception, so a real open-competition share must remain.
• Strict judicial test: In Jaishri Laxmanrao Patil (2021), the Supreme Court found no exceptional circumstances for the Maratha quota and refused to revisit Indra Sawhney [4].
• Breaches invite more breaches: Karnataka's own Act cites other States crossing 50% to justify its hike [2].
• Population share is not the same as under-representation: The EWS majority held that the cap governs caste-based quotas, which places SC/ST quotas inside it [5]. Benefits also concentrate among better-off sub-groups, which is why Davinder Singh (2024) allowed sub-classification [6].
• Ninth Schedule is not a safe harbour: After I.R. Coelho (2007), laws placed in it can still be tested against the basic structure.

Balanced assessment

• Crossing 50% is defensible only with quantifiable, contemporaneous data showing SC/ST representation department by department and grade by grade.
• Rebalancing the shares within 50% should be tried before breaching the cap.
• A larger bench should reconcile Patil with Janhit Abhiyan.

Proportionality is a valid moral claim, but it is not an automatic constitutional right. A middle path works best: rigorous data, sub-classification, and clear guidance from a larger bench. This would let SC/ST quotas grow where the evidence shows under-representation, in line with Article 46 and SDG 10.
