Amid confusion over internal reservation, Karnataka SC/ST commission holds deliberations

What Happened

  • The Karnataka State Commission for Scheduled Castes and Scheduled Tribes convened deliberations with senior officials, former Karnataka Public Service Commission (KPSC) functionaries, and community representatives over the ongoing confusion regarding implementation of internal reservation within the SC category.
  • A parallel dispute concerns the overall reservation ceiling: the State reduced the combined SC/ST reservation from 56% to 50% for recruitment to 56,432 posts, in apparent compliance with the Supreme Court's 50% cap doctrine, triggering protests from communities that benefited from the higher quota.
  • The confusion stems from the landmark Supreme Court ruling in State of Punjab v. Davinder Singh (2024), which permitted states to sub-classify the SC list for reservations, overruling the previous 2004 position that SCs form a homogenous group.
  • Karnataka had constituted a one-man commission (October 2024) to recommend sub-classification ratios within the 17% SC quota after the Cabinet gave in-principle approval for internal reservation.
  • Community representatives are seeking clarity on how sub-categories will be defined, the data basis for quotas within the quota, and a timeline for implementation.

State of Punjab v. Davinder Singh (2024): Sub-Classification Within SC/ST Quotas

On August 1, 2024, a 7-judge Constitution Bench of the Supreme Court delivered a 6:1 majority verdict in State of Punjab v. Davinder Singh (2024 INSC 562), holding that state governments have the power to sub-classify Scheduled Castes (and by extension Scheduled Tribes) within the presidential list for the purpose of reservations in public employment and education. The Court overruled its 2004 decision in E.V. Chinnaiah v. State of Andhra Pradesh, which had treated the entire SC presidential list as a single, homogenous class impermissible of further subdivision.

  • The 2004 E.V. Chinnaiah bench (5 judges) had held that the SC list under Article 341 constitutes a single indivisible group; any sub-classification would amount to tinkering with the Presidential list — a power vested exclusively in Parliament.
  • The 2024 bench (7 judges) held that Scheduled Castes are not homogenous; historical discrimination has affected sub-groups within the SC list to varying degrees, and states may use quantifiable, demonstrable empirical data to justify sub-classification.
  • The sole dissent was by Justice Bela M. Trivedi, who upheld the E.V. Chinnaiah position.
  • The ruling expressly requires that sub-classification be backed by data — not political preference — and that no sub-group should be allocated 100% of the sub-quota (creamy layer principle may also be considered for SCs in future).
  • CJI DY Chandrachud led the 7-judge bench; the judgment was delivered on the last day of his tenure as CJI.

Connection to this news: Karnataka's commission is now doing exactly what the Supreme Court mandated — gathering empirical data and consulting stakeholders to build the evidentiary basis for sub-classification, rather than proceeding on political considerations alone.

Constitutional Basis of Reservations: Articles 15, 16, and 341

The reservation framework in India rests on Articles 15(4) and 15(5) (special provisions for SCs, STs, OBCs in education) and Article 16(4) and 16(4A) (reservation in public employment and promotions). The SC presidential list is constituted under Article 341 — only the President can notify SCs, and Parliament can modify the list by law; states cannot add or remove communities from it.

  • Article 341(1): The President, after consultation with the Governor, may specify which castes/races/tribes shall be deemed SCs in a state.
  • Article 341(2): Parliament by law may include/exclude any caste from the presidential list.
  • Article 16(4A): States may provide reservation in promotion with consequential seniority for SCs/STs if they are not adequately represented. Inserted by the 77th Amendment (1995); further modified by 85th Amendment (2001).
  • The 50% ceiling on reservations was established in Indra Sawhney v. Union of India (1992) — the Mandal case — as a general rule, subject to extraordinary circumstances (the Tamil Nadu case of 69% was upheld as an exception under the Ninth Schedule).
  • Internal reservation or sub-classification does not alter the total percentage reserved; it redistributes the existing quota among sub-groups within the SC list.

Connection to this news: Karnataka's reduction from 56% to 50% is a direct consequence of the Indra Sawhney ceiling; the internal sub-classification operates within the remaining 17% SC quota and does not affect the ceiling but redistributes its benefits.

The Karnataka Reservation History and SC Internal Categorisation

Karnataka's SC community is internally diverse, comprising communities like Holeya, Madiga, Bhovi, and others who have historically competed for the same 17% SC quota. Madiga leaders across southern states have long demanded sub-classification so that dominant SC sub-groups do not capture a disproportionate share of government jobs and education seats. The Andhra Pradesh sub-classification attempt — struck down in E.V. Chinnaiah (2004) — was specifically motivated by this Madiga demand; the 2024 ruling reopens this possibility.

  • Karnataka notified a one-man commission under a retired judge in October 2024, following the Davinder Singh verdict.
  • The commission is tasked with recommending sub-quota proportions based on population share and representation data.
  • Any sub-classification notification by the State must withstand judicial scrutiny — it will need to demonstrate quantifiable backwardness data per sub-group.
  • The KPSC and state government face administrative complexity: existing recruitments under the undivided SC quota must be reconciled with any new sub-categorised system.
  • The 56% to 50% reduction in combined SC/ST quotas for the 56,432-post recruitment reflects adherence to the Indra Sawhney general ceiling and is a separate issue from internal sub-classification.

Connection to this news: The commission's deliberations are the critical implementation step between the Supreme Court's 2024 green light and actual policy change; any sub-classification without adequate data will be vulnerable to fresh legal challenge.
