What Happened

Karnataka has restructured its internal reservation quotas to remain within the 50% ceiling mandated by the Supreme Court, following the landmark August 2024 judgment permitting sub-classification within Scheduled Caste (SC) reservations.
The state government issued an order implementing a revised sub-classification formula within the existing 15% SC quota: 5.25% for Category A (Madigas and allied castes), 5.25% for Category B (Holeyas and allied castes), and 4.5% for Category C — totalling the existing 15% with no net increase.
The Karnataka High Court had directed the government not to breach the 50% reservation ceiling, and the state has recalibrated its formula in compliance.
With SC 15% (sub-classified) + ST 3% + OBC 32% = 50%, Karnataka has rearranged its internal allocation without expanding the total quantum, staying precisely at the constitutional ceiling.

Static Topic Bridges

Indra Sawhney v. Union of India (1992) — The 50% Ceiling Rule

The Indra Sawhney case (also called the Mandal verdict) is the cornerstone judgment governing reservations in India. A nine-judge Constitution Bench of the Supreme Court, delivering its verdict on November 16, 1992, upheld the 27% OBC reservation in central government jobs while laying down critical limits on the reservation system.

The Bench ruled that total reservation (SC + ST + OBC) must not ordinarily exceed 50% of available posts or seats.
Exceptions to the 50% ceiling may be made only in "extraordinary circumstances" relating to backwardness of certain regions.
The ruling upheld the concept of the "creamy layer" — the exclusion of the socially and economically advanced segments from OBC benefits.
Reservations in promotions were held not to be permissible (subsequently addressed through the 77th, 81st, and 85th Constitutional Amendments).
The 50% ceiling has been upheld in subsequent cases, including the 2021 Maratha reservation case (Jaishri Laxmanrao Patil v. Chief Minister, Maharashtra), where a five-judge bench struck down the Maratha quota for breaching the ceiling.

Connection to this news: Karnataka's exercise of sub-classifying its SC quota while keeping the total at 50% is a textbook compliance strategy — the state uses the Davinder Singh judgment to achieve greater intra-category equity while scrupulously staying within Indra Sawhney's ceiling.

State of Punjab v. Davinder Singh (2024) — Sub-Classification Upheld

On August 1, 2024, a seven-judge Constitution Bench of the Supreme Court held (6:1) that states can create sub-quotas within the Scheduled Caste reservation category to direct a larger share to the most marginalised sub-groups within SCs.

The judgment overruled the earlier five-judge bench decision in E.V. Chinnaiah v. State of Andhra Pradesh (2004), which had held that SCs form a homogenous class and cannot be sub-divided for reservation purposes.
The 2024 judgment held that intra-SC inequality is empirically documented and that sub-classification is a constitutionally valid tool to achieve substantive equality.
The dissent by Justice Bela Trivedi held that sub-classification effectively re-classifies communities within the Presidential List, which only Parliament can do under Article 341.
The judgment does not allow states to create a new class; they can only allocate proportions within the existing presidential list of SCs.
Sub-classification must be backed by empirical data showing inadequate representation of a sub-group.

Connection to this news: Karnataka's 5.25–5.25–4.5 sub-formula within its 15% SC quota is a direct implementation of the Davinder Singh judgment, addressing the historical dominance of certain SC sub-groups in accessing reservations over others.

Article 15(4) and 16(4) — Constitutional Basis for Reservations

Articles 15(4) and 16(4) provide the constitutional authority for the state to make special provisions for the advancement of socially and educationally backward classes (SEBCs) and for SCs and STs.

Article 15(4) was inserted by the Constitution (First Amendment) Act, 1951, specifically to overturn the Supreme Court's decision in State of Madras v. Champakam Dorairajan (1951), which had struck down caste-based reservations in educational institutions.
Article 16(4) enables reservation in public employment; Article 16(4A) enables reservation in promotions for SCs and STs (inserted by the 77th Amendment, 1995).
Article 341 gives Parliament the exclusive power to specify which castes are included in the Presidential List of Scheduled Castes; states cannot add or remove from this list.
The tension between the non-sub-divisibility of the Presidential List (Article 341) and sub-classification within it is the central doctrinal dispute addressed in Davinder Singh (2024).

Connection to this news: Karnataka's sub-classification order exercises state power under Articles 15(4) and 16(4), while remaining bounded by Article 341 (using the existing presidential list) and Indra Sawhney's 50% ceiling.
