Centre opposes pleas for income-based creamy layer in SC/ST quotas
The Union government, through the Ministry of Social Justice and Empowerment, filed an affidavit opposing petitions before the Supreme Court that seek an income-based "creamy layer" sub-classification within Scheduled Caste (SC) and Scheduled Tribe (ST) reservation.
The petitions, including one filed by Ramashankar Prajapati and others (W.P.(C) No. 682/2025) and another by an advocate, seek a "merit-cum-means" approach — directing the exclusion of economically better-off individuals from SC/ST reservation benefits, similar to the creamy layer principle applied to Other Backward Classes (OBCs).
The Centre's affidavit argues that identification of SCs and STs rests on historical and social backwardness rather than economic status alone, and that any change to who qualifies as SC/ST can only be made by Parliament through law, not by judicial direction to the executive.
The Centre further submitted that any policy shift on income-based exclusion within reserved categories would require a holistic review and empirical socio-economic study, not a one-off judicial directive.
The matter remains pending before the Supreme Court, which had earlier issued notice on the lead petition.
Articles 341 and 342 — Constitutional Basis for SC/ST Identification
Article 341 empowers the President to notify castes, races, or tribes (or parts/groups within them) as Scheduled Castes for a given state or union territory, after consultation with the Governor where applicable; Article 342 provides an identical mechanism for Scheduled Tribes. Once notified, this list can be amended only by Parliament through law — not by the President's subsequent notification, nor by any court or state government.
Key Details
- Article 341(2) and Article 342(2) specify that Parliament alone may, by law, include in or exclude from the notified SC/ST list any caste, race, or tribe (or part/group within one); a subsequent presidential notification alone cannot vary the list.
- Article 342A, inserted by the 102nd Constitutional Amendment Act, 2018, created a parallel mechanism for the Central List of Socially and Educationally Backward Classes (SEBCs/OBCs) at the central level, following the same "law by Parliament" logic.
- In E.V. Chinnaiah v. State of A.P. (2004), a five-judge bench held that Scheduled Castes notified under Article 341 form a single, homogeneous class that state legislatures cannot sub-classify for preferential treatment — a holding that stood until it was overruled twenty years later.
- The Centre's affidavit invokes Articles 341 and 342 to argue that any exclusion of a "creamy layer" from the SC/ST lists — which would effectively narrow who counts as SC/ST for reservation purposes — is a legislative act reserved to Parliament, not a matter courts can direct the executive to implement.
The Centre's core constitutional objection to the pending petitions is jurisdictional: excluding a creamy layer from SC/ST would alter who is treated as belonging to the notified list, which Articles 341(2)/342(2) reserve exclusively to Parliament.
Indra Sawhney v. Union of India (1992) — Origin of the Creamy Layer Principle
A nine-judge bench of the Supreme Court, deciding the Mandal Commission reference on November 16, 1992, upheld 27% reservation for OBCs in central government jobs while introducing the "creamy layer" doctrine — the principle that socially advanced members within a backward class must be excluded from reservation benefits, since they no longer share the disadvantage that justifies preferential treatment.
Key Details
- The judgment interpreted Article 16(4) as a facet of the equality guarantee in Article 16(1), not an exception to it, and fixed a general ceiling of 50% on total reservations (subject to extraordinary circumstances).
- The creamy layer principle was developed specifically in the context of OBC reservation, to distinguish "backward classes" (which can include caste-based groups where social and economic advancement is possible) from SCs and STs (constitutionally notified lists under Articles 341/342, treated as a distinct category).
- The Centre's affidavit relies on Indra Sawhney to argue that the creamy layer discussion in that judgment was "confined to OBCs" and has no direct application to SC/ST reservation.
The pending petitions effectively ask the Court to extend a principle Indra Sawhney developed for OBCs to SC/ST reservation — the Centre's opposition rests substantially on confining that precedent to its original OBC context.
State of Punjab v. Davinder Singh (2024) — Sub-Classification and the Creamy Layer Question for SC/ST
A seven-judge Constitution bench, on August 1, 2024, held by a 6:1 majority that state legislatures can sub-classify Scheduled Castes for reservation purposes to extend preferential treatment to the most disadvantaged sub-groups within the SC list, overruling the earlier five-judge ruling in E.V. Chinnaiah v. State of A.P. (2004) that had barred such sub-classification.
Key Details
- The main opinion was authored by the then Chief Justice of India, D.Y. Chandrachud, with concurring separate opinions by other judges; Justice Bela M. Trivedi dissented.
- Although the specific question of sub-classification was the core issue decided, the judgment is also cited for obiter observations on the creamy layer: in a separate opinion, it was suggested that a "creamy layer"-type identification criterion could, in principle, apply differently within SCs and STs than it does for OBCs — an observation on which four of the seven judges expressed some degree of agreement, even though it was not the central issue framed for the bench.
- The ruling permits states to grant preferential treatment to more backward sub-groups within the SC list (sub-classification) but does not itself direct exclusion of a creamy layer from SC/ST reservation altogether — the two are analytically distinct: sub-classification redistributes benefits within SCs, while creamy layer exclusion removes some individuals from SC/ST reservation entirely.
- The Centre's affidavit treats the creamy layer observations in this 2024 verdict as non-binding obiter, distinct from its operative holding on sub-classification, and maintains that no binding precedent extends the creamy layer doctrine to SC/ST reservation as such.
Petitioners likely draw on the creamy layer observations in Davinder Singh (2024) to argue judicial support exists for excluding well-off SC/ST individuals; the Centre's affidavit counters by distinguishing the binding holding (sub-classification is constitutionally permissible) from the non-binding observations on creamy layer, and by reiterating that any such exclusion requires parliamentary legislation, not the Court's directive.
Distinguishing "Sub-Classification" from "Creamy Layer Exclusion"
These are two separate, sometimes conflated, reservation concepts relevant to current SC/ST policy debates. Sub-classification creates internal categories within SC/ST reservation to prioritise the most disadvantaged sub-groups (permitted since Davinder Singh, 2024). Creamy layer exclusion removes economically/socially advanced individuals from reservation eligibility altogether (settled law only for OBCs, per Indra Sawhney, 1992, and reaffirmed for OBCs specifically in later rulings such as Ashoka Kumar Thakur v. Union of India, 2008).
Key Details
- Sub-classification requires the state to identify empirical inter-se backwardness data among SC sub-groups, a requirement the Supreme Court underscored in Davinder Singh (2024).
- Creamy layer exclusion for OBCs is operationalised through income/status ceilings prescribed via central government office memoranda (periodically revised, most recently a gross annual income ceiling in the several-lakh-rupee range, distinct from any SC/ST norm).
- No statutory or constitutional creamy layer ceiling currently exists for SC/ST reservation; introducing one would require either a constitutional amendment process or parliamentary legislation altering the effect of Articles 341/342, per the Centre's stated position.
The current litigation sits precisely at the boundary between what is already permitted (sub-classification, post-2024) and what remains contested and, per the Centre, requires parliamentary action rather than judicial direction (creamy layer exclusion from SC/ST reservation).
