Supreme Court Judgment on Reservation: Overview
The question of whether Scheduled Castes and Scheduled Tribes can be treated as internally diverse groups — with more backward sub-castes entitled to preferential treatment within the existing reservation quota — is one of the most consequential reservation-law questions the Supreme Court has decided in recent years. The case, State of Punjab & Ors. v. Davinder Singh & Ors., arose from a Punjab law reserving half of SC-category vacancies for two specific, more disadvantaged communities within the SC list.
Decided by a seven-judge Constitution Bench on 1 August 2024, and upheld on review on 9 October 2024, the judgment overturned two decades of settled law and reopened the question of how reservation benefits should be distributed within the SC/ST categories. This page explains the judgment, the framework it lays down, and its practical implementation across India.
What Was the Case About?
In 2006, the Punjab government enacted a law reserving 50% of vacancies in the Scheduled Castes category specifically for Balmikis and Mazhabi Sikhs — two communities considered more disadvantaged than other Scheduled Castes in the State. The Punjab and Haryana High Court struck down this law in 2010, relying on the Supreme Court's earlier five-judge ruling in E.V. Chinnaiah v. State of Andhra Pradesh (2004), which had held that all Scheduled Castes notified under Article 341 of the Constitution form a single, homogeneous class that states have no power to further sub-divide for reservation purposes. The State of Punjab appealed to the Supreme Court, which referred the matter to a larger seven-judge Bench to reconsider the correctness of Chinnaiah.
The Main Legal Question
The central issue was whether States possess constitutional authority to sub-classify Scheduled Castes and Scheduled Tribes within their reserved quota, in order to extend preferential treatment to castes or tribes that are more backward than others within these already-reserved categories, and if so, what safeguards must govern such sub-classification to prevent it from being used arbitrarily or to benefit only politically favoured groups.
Key Directions and Observations (Judgment Dated 1 August 2024)
The following is a structured, plain-English summary of what the seven-judge Bench held and the framework it laid down for States wishing to sub-classify.
E.V. Chinnaiah Overruled — Sub-Classification Permitted
By a 6-1 majority, the Court overruled its 2004 ruling in E.V. Chinnaiah v. State of Andhra Pradesh, holding that Scheduled Castes and Scheduled Tribes are not a single homogeneous class, and that States can sub-classify them to extend differentiated treatment to more backward sub-groups within the existing quota.
Sub-Classification Must Rest on Empirical Data
Any sub-classification cannot be based on political expediency or the whim of the State — it must be justified by empirical data and historical evidence demonstrating systemic discrimination and inadequate representation of the sub-group in question.
No 100% Reservation for Any Single Sub-Class
A State cannot allocate the entirety of the SC or ST reservation quota to a single sub-class to the total exclusion of others — the Court held that reserving 100% of the quota for one sub-category, as had happened in the underlying Punjab law, is impermissible.
Creamy Layer Principle Extended to SCs/STs
Echoing the creamy-layer principle first applied to OBCs in Indra Sawhney, the majority held that States should evolve a policy to identify and exclude the "creamy layer" within SCs/STs, so reservation benefits remain targeted at the genuinely disadvantaged, particularly limiting benefits to the first generation of beneficiaries within a family.
Relevant Legal Framework
Several constitutional provisions and precedents together govern how reservation for Scheduled Castes and Scheduled Tribes operates in India. Understanding which provision is relevant to your situation is often the first step in getting the right advice.
| Article 341 & 342, Constitution of India | Empower the President to specify which castes and tribes are deemed Scheduled Castes or Scheduled Tribes for a State or Union Territory, forming the basis of the "single homogeneous class" argument the Court reconsidered. |
|---|---|
| Article 14 & 16(4), Constitution of India | Guarantee equality before law and permit the State to make special provision for reservation in favour of backward classes inadequately represented in public employment — the constitutional basis for sub-classification as a tool for substantive equality. |
| Article 15(4) & 15(5), Constitution of India | Permit special provisions for socially and educationally backward classes, including SCs and STs, for advancement and admission to educational institutions. |
| Indra Sawhney v. Union of India (1992) Supp (3) SCC 217 | The nine-judge "Mandal" judgment that upheld OBC reservation and introduced the "creamy layer" concept, later extended by the Davinder Singh Bench to SCs and STs. |
| E.V. Chinnaiah v. State of Andhra Pradesh (2004) 8 SCC 705 (Overruled) | The previous five-judge ruling that had held SCs to be a single, indivisible class under Article 341, now overruled by the seven-judge Bench in Davinder Singh. |
| State-Specific Sub-Classification Legislation | Laws such as Punjab's 2006 Act and Telangana's implementation scheme, which must now be tested against the empirical-data and creamy-layer safeguards laid down in Davinder Singh. |
Timeline of Important Court Proceedings
Punjab Enacts Sub-Classification Law
The Punjab government reserves 50% of SC-category vacancies specifically for Balmikis and Mazhabi Sikhs, considered more disadvantaged than other Scheduled Castes in the State.
Punjab & Haryana High Court Strikes Down the Law
Relying on E.V. Chinnaiah v. State of Andhra Pradesh (2004), the High Court holds that Scheduled Castes form a homogeneous class that cannot be sub-divided, striking down the 2006 Punjab law.
Matter Referred to a Larger Bench
The Supreme Court refers the question of whether E.V. Chinnaiah requires reconsideration to a seven-judge Constitution Bench, given the significance of the issue for reservation policy nationwide.
Judgment Delivered — Sub-Classification Permitted
A seven-judge Bench, by 6-1 majority, overrules E.V. Chinnaiah and holds that States can sub-classify SCs/STs for reservation purposes, subject to empirical justification, no 100% allocation to one sub-class, and a creamy-layer exclusion.
Review Petitions Dismissed
The same seven-judge Bench, led by then-CJI D.Y. Chandrachud, dismisses review petitions challenging the judgment, finding "no error apparent on the face of the record," cementing the ruling as settled law.
Uneven State-Wise Implementation
Telangana remains the only State to have fully implemented sub-classification as of September 2026; the Union Government has not yet issued nationwide implementation directions, and the Supreme Court has sought a compliance report on the judgment's implementation across States.
What Does This Judgment Mean in Practice?
For SC/ST Candidates from More Backward Sub-Castes
If your State implements sub-classification based on empirical data, you may become entitled to a dedicated sub-quota within the broader SC/ST reservation, potentially improving your chances in recruitment and admissions relative to more advanced sub-castes within the same category.
For SC/ST Candidates from Relatively Advanced Sub-Castes
Sub-classification could mean your sub-caste receives a smaller proportional share of the quota than before, and the "creamy layer" principle may eventually be used to exclude economically or socially advanced individuals within SCs/STs from benefits.
For State Governments
States wishing to sub-classify must first commission or rely on empirical data (such as a dedicated commission's study, as Telangana did) demonstrating differential backwardness — a bare executive or political decision without such data is vulnerable to legal challenge.
For Employers & Educational Institutions
Recruitment and admission processes in States that have implemented sub-classification must apply the sub-quota framework correctly, and should expect increased scrutiny and litigation as more States adopt or contest sub-classification schemes.
Guidance for Reservation Beneficiaries and for State Authorities
This judgment affects different groups differently — from an individual SC/ST candidate wondering how a State's sub-classification scheme affects their own prospects, to a State government deciding whether and how to implement sub-classification. What you should do next depends on which situation applies to you.
If You Are an SC/ST Candidate or Job Aspirant
- Check whether your State has implemented SC/ST sub-classification, and if so, which sub-category your caste falls under and what proportional quota applies.
- Keep documentary proof of your caste certificate and any sub-category classification relevant to recruitment or admission processes.
- If your State has not implemented sub-classification, understand that the existing, undivided SC/ST quota continues to apply to you as before.
- If you believe a State's sub-classification scheme lacks empirical justification or unfairly disadvantages your sub-caste, consult a lawyer about challenging it.
- Stay updated on Union Government guidance, since national-level implementation directions may still be issued following the Supreme Court's compliance review.
If You Represent a State Government or Public Authority
- Commission or rely on robust empirical data — covering population, literacy, employment, education access and political participation — before framing any sub-classification scheme, following the Telangana model.
- Ensure no single sub-class is allocated 100% of the reserved quota, and that the scheme reflects proportional representation among sub-castes.
- Develop a policy addressing the "creamy layer" within SCs/STs, consistent with the Court's direction, to keep benefits targeted at genuinely disadvantaged individuals.
- Be prepared for legal challenges to any sub-classification scheme that lacks a documented empirical basis.
- Track Union Government guidance and the Supreme Court's ongoing compliance review before finalising or amending a sub-classification policy.
Does This Judgment Apply to Your Situation?
Whether sub-classification affects your specific recruitment, admission or promotion depends heavily on whether your State has implemented it, and if so, on the precise scheme adopted. Not all States have acted on this judgment.

State of Punjab & Ors. v. Davinder Singh & Ors.
The seven-judge Bench held, by 6-1 majority, that States can sub-classify SCs/STs for preferential treatment of more backward sub-groups within the existing quota, subject to empirical justification and a creamy-layer safeguard.
E.V. Chinnaiah v. State of Andhra Pradesh
The previous five-judge ruling holding that Scheduled Castes notified under Article 341 form a single, homogeneous class that a State legislature has no power to further sub-divide for reservation purposes.
Indra Sawhney v. Union of India ("Mandal Commission" Case)
The nine-judge Bench that upheld 27% OBC reservation in government jobs, capped total reservation at roughly 50%, and introduced the "creamy layer" concept to exclude the socially and economically advanced among OBCs from reservation benefits.
Telangana's Three-Tier SC Sub-Classification Scheme
Telangana became the first State to implement sub-classification following Davinder Singh, dividing SCs into three groups based on population, literacy, employment, education access, financial aid and political participation, allocating 1%, 9% and 5% out of the State's 15% SC quota.
Economically Weaker Sections (EWS) Reservation Upheld
A five-judge Bench upheld 10% reservation for Economically Weaker Sections among the general category, holding that economic criteria alone can form a valid basis for reservation, distinct from but part of the broader constitutional reservation jurisprudence.
