"Caste enumeration is essential for evidence-based reservation policy, yet politically and judicially contentious." Discuss with reference to recent state-level caste surveys.

Reservation is a data-dependent policy, yet caste has never been counted for the general population since Independence [2]. Recent state surveys show that filling this evidentiary gap is necessary, but it collides with competitive politics and constitutional limits.

Why enumeration is essential

• Articles 15(4) and 16(4) require identification of socially and educationally backward classes; in Indra Sawhney (1992) the Supreme Court held caste to be an acceptable indicator of backwardness [7]. Identification without enumeration rests on dated estimates.
• The Union Cabinet accordingly approved caste enumeration in Census 2027 [1], to be captured in the Population Enumeration phase — the first full-population caste count since Independence [2].
• States acted earlier to fill the vacuum: Bihar's caste-based survey (2022-23), tabled before the Assembly [5], and Karnataka's Socio-Educational Survey by the State Commission for Backward Classes, conducted from 22 September 2025 and extended to 31 October at a cost of about ₹420 crore [3].

Political contention

• Enumeration converts caste shares into claims. In Karnataka, the earlier Kantharaj Commission report was never accepted by the government, forcing a fresh survey a decade later [4] — dominant communities feared a smaller-than-assumed count.
• Findings immediately drive quota demands; Karnataka has already raised SC/ST reservation to 24% [8], while backward-class groups press for proportionate shares.
• Risks include intra-OBC rivalry, boycott calls, and treating data as electoral currency rather than a welfare-targeting tool.

Judicial contention

• The 50% ceiling laid down in Indra Sawhney permits breach only in extraordinary circumstances [7].
• The Patna High Court struck down Bihar's hike of quotas to 65%, which had followed its survey [6] — a reminder that data alone cannot justify exceeding the cap.

Caste data is thus a means of precision, not a licence for expansion. Its credibility depends on transparent methodology, timely publication, and use for budgetary and welfare targeting alongside quotas. Census 2027 offers a uniform national baseline [1] that can align reservation with the Constitution's promise of substantive equality while respecting judicial safeguards.
