2. Introduction

This case concerns whether state governments possess the constitutional authority to sub-classify Scheduled Castes (SCs) and Scheduled Tribes (STs) for the purpose of distributing reservation benefits more equitably among them. The question required the Supreme Court to reconsider its own 2004 ruling in E.V. Chinnaiah v. State of Andhra Pradesh, which had held that all castes notified as Scheduled Castes under Article 341 form a single, homogeneous class that cannot be further divided by any legislature. The case is significant because it addresses a long-recognised problem within India’s reservation framework: that certain sub-groups within the SC/ST categories have historically captured a disproportionate share of reservation benefits, leaving the most disadvantaged sub-castes underrepresented despite being nominally part of the same reserved category.

3. Facts of the Case

The Punjab Scheduled Castes and Backward Classes (Reservation in Services) Act, 2006 contained Section 4(5), which granted “first preference” within the SC quota in public employment to two specific communities, the Balmikis and the Mazhabi Sikhs, on the ground that they were more backward than other Scheduled Castes in the State. This provision was challenged before the Punjab and Haryana High Court, which struck it down as unconstitutional, relying squarely on the Supreme Court’s 2004 decision in E.V. Chinnaiah v. State of Andhra Pradesh. In Chinnaiah, a five-judge bench had held that once a caste is included in the Presidential list of Scheduled Castes under Article 341, it becomes part of a single, indivisible constitutional class, and that no state legislature has the power to sub-divide that class or grant preferential treatment to any sub-group within it for reservation purposes.

The State of Punjab appealed the High Court’s ruling to the Supreme Court. A related question had also arisen in Haryana, where a 1994 government notification classifying Scheduled Castes into Blocks A and B for reservation purposes had similarly been quashed by the High Court on the basis of Chinnaiah. Given the recurring nature of this issue across multiple states and its far-reaching implications for reservation policy, a five-judge bench of the Supreme Court in 2020 doubted the correctness of Chinnaiah and referred the matter to a larger seven-judge Constitution Bench for authoritative reconsideration. The seven-judge bench heard extensive arguments and delivered its judgment on 1 August 2024.

4. Legal Issues

Issue 1: Whether Scheduled Castes and Scheduled Tribes notified under Articles 341 and 342 constitute a homogeneous class that is constitutionally incapable of further sub-classification.

Issue 2: Whether state legislatures have the power to sub-classify SCs and STs to grant preferential treatment to more disadvantaged sub-groups within those categories, consistent with Articles 14, 15, and 16 of the Constitution.

Issue 3: Whether E.V. Chinnaiah v. State of Andhra Pradesh (2004) correctly interpreted the Constitution on this question, and whether it should be overruled.

Issue 4: If sub-classification is permissible, what safeguards or evidentiary standards must a state satisfy before implementing it?

5. Arguments Presented

Appellant’s (State of Punjab’s) Arguments:

The State argued that treating all Scheduled Castes as a single homogeneous class ignores significant empirical disparities in social and educational backwardness among different sub-castes within that category, allowing more advanced sub-groups to disproportionately capture reservation benefits meant for the most disadvantaged. It contended that sub-classification, when supported by credible data, is a rational and permissible method of achieving substantive equality under Articles 14, 15, and 16, and that Chinnaiah’s rigid, category-based approach failed to account for these internal disparities. The State further argued that Article 341 merely identifies which castes are eligible for reservation as a constitutional matter, but does not preclude a state from calibrating how benefits are distributed among eligible sub-groups.

Respondents’ Arguments:

The respondents, defending the High Court’s reliance on Chinnaiah, argued that the Presidential list under Article 341 creates a single, unified constitutional class that cannot be fragmented by state action, since allowing sub-classification would enable states to indirectly exclude or disadvantage certain notified castes, undermining the integrity of the Article 341 list. They contended that Chinnaiah had correctly protected against the risk of majoritarian or politically motivated sub-division within the SC category, and that a settled precedent of two decades’ standing, on a matter directly affecting a constitutionally protected class, should not be disturbed absent compelling justification.

6. Court’s Reasoning and Analysis

Writing for the majority, the Chief Justice held that the Scheduled Castes, despite being clubbed together in a single Presidential notification under Article 341, are not internally homogeneous but comprise numerous castes with varying degrees of social, educational, and economic backwardness. The majority reasoned that treating this diverse list as an undifferentiated class for reservation purposes, as Chinnaiah had done, defeats rather than serves the constitutional goal of substantive equality, because it permits relatively better-placed sub-castes within the SC category to consistently secure a larger share of reservation benefits, leaving the most disadvantaged sub-groups persistently underrepresented.

The majority clarified that Article 341 performs the limited function of identifying which castes qualify for inclusion in the Scheduled Castes category as a matter of constitutional recognition; it does not thereby freeze that category into an indivisible bloc immune from any further calibration by the state. Drawing on the equality jurisprudence developed in Indra Sawhney v. Union of India concerning sub-classification of Other Backward Classes, the majority extended a broadly analogous logic to SCs and STs, holding that states may identify more backward sub-groups within these categories and grant them preferential access to reservation benefits, provided such classification is based on credible, tangible data demonstrating comparative backwardness, and is not applied so as to deny all representation to any sub-group altogether. The Court also emphasised that any such sub-classification remains subject to judicial review and must not be exercised for extraneous political considerations.

Justice Bela M. Trivedi, dissenting, reasoned that Chinnaiah correctly reflected the constitutional design, since Article 341 vests the President, in consultation with the Governor and subject to parliamentary law, with exclusive authority to specify which castes fall within the Scheduled Castes list, precisely to insulate that list from alteration by other authorities, including state legislatures. She held that permitting states to sub-classify this list would effectively allow states to amend a constitutionally entrenched classification through ordinary legislation, and expressed concern that the majority had referred the matter to a larger bench and overturned settled precedent without adequately articulating cogent reasons for departing from Chinnaiah’s reasoning of two decades’ standing.

7. Judgment and Ratio Decidendi

By a 6:1 majority, the Supreme Court overruled E.V. Chinnaiah v. State of Andhra Pradesh (2004) and held that state governments possess the constitutional power to sub-classify Scheduled Castes and Scheduled Tribes for the purpose of extending preferential treatment within reservation quotas to the most disadvantaged sub-groups. The Court accordingly restored the validity of Section 4(5) of the Punjab Scheduled Castes and Backward Classes (Reservation in Services) Act, 2006, insofar as it granted first preference to the Balmiki and Mazhabi Sikh communities, subject to such classification being founded on empirical evidence of comparative backwardness rather than mere political expediency.

Ratio Decidendi: Scheduled Castes and Scheduled Tribes notified under Articles 341 and 342 do not constitute a constitutionally indivisible homogeneous class; states may validly sub-classify these categories to grant preferential reservation treatment to more backward sub-groups, provided the classification is based on credible data demonstrating comparative disadvantage and is not exercised arbitrarily or for extraneous purposes.

8. Critical Analysis

The majority’s ruling responds to a genuine and long-documented problem in India’s reservation framework: the tendency of relatively advantaged sub-castes within the broader SC and ST categories to disproportionately capture reservation benefits, while the most marginalised sub-groups remain persistently underrepresented despite formal eligibility. By permitting states to calibrate reservation policy using empirical data on comparative backwardness, the judgment moves the equality analysis under Articles 14, 15, and 16 closer to a substantive, outcome-oriented conception of equality, rather than a purely formal one that treats all notified castes identically regardless of demonstrated disparities.

At the same time, the dissent’s institutional concern deserves serious weight. Article 341 was deliberately structured to place the identification of Scheduled Castes beyond the reach of ordinary political processes, precisely to prevent majoritarian or politically motivated exclusion of vulnerable groups from constitutional protection. Permitting sub-classification, even subject to an evidentiary standard, creates a mechanism through which states could, in principle, functionally redistribute or dilute benefits away from certain notified castes without formally removing them from the Article 341 list, raising a risk that the ruling’s safeguards, requiring “credible data” and prohibiting arbitrary exclusion, will need robust and consistent judicial enforcement to prevent misuse.

A further practical concern is administrability: identifying which sub-castes qualify as comparatively more backward requires reliable, updated empirical data that many states currently lack, and the absence of clear, uniform methodological standards for such determinations may generate inconsistent outcomes and repeated litigation across states. On balance, however, the majority’s approach represents a more defensible reading of the constitutional equality guarantee than Chinnaiah’s rigid formalism, provided its implementation is anchored in rigorous, transparent, and periodically updated empirical assessment rather than discretionary state action.

9. Conclusion

The Davinder Singh judgment marks a significant recalibration of India’s reservation jurisprudence, overruling a twenty-year-old precedent that had treated Scheduled Castes and Scheduled Tribes as constitutionally indivisible categories. Its key takeaway is that formal inclusion within a single constitutional list does not preclude states from recognising and addressing meaningful disparities of backwardness among sub-groups within that list, provided such action rests on credible evidence rather than political convenience. While the ruling opens the door to more equitable distribution of reservation benefits, its lasting impact will depend heavily on how states collect data, define comparative backwardness, and apply sub-classification in practice, leaving important questions of implementation and judicial oversight to be worked out in the years ahead.
