Key Highlights

  • Supreme Court’s 6:1 majority verdict in 2024 overrules E.V. Chinnaiah (2004) allowing states to sub-classify SC/ST communities based on empirical evidence of varying backwardness
  • Four judges advocate creamy layer principle for SC/ST communities despite constitutional distinction from OBCs, creating controversy over economic versus caste-based discrimination
  • Constitutional Articles 341/342 grant Presidential notification power while states gain legislative authority for sub-classification without tampering with Central lists
  • Telangana becomes first state implementing SC sub-classification with separate quotas demonstrating practical application of new jurisprudential framework
  • Empirical data requirement for sub-classification necessitates caste census-like enumeration raising politically sensitive questions about comprehensive data collection

India’s reservation system stands as one of the world’s most comprehensive affirmative action frameworks, designed to address historical injustices and promote substantive equality for marginalized communities. The recent Supreme Court judgment in State of Punjab v. Davinder Singh (2024), delivered by a 7-judge Constitution Bench with a 6:1 majority, has fundamentally altered the reservation landscape by overruling the 2004 E.V. Chinnaiah decision and permitting sub-classification within Scheduled Castes and Scheduled Tribes. This landmark verdict, spanning 565 pages with six separate concurring opinions, not only addresses the heterogeneous nature of reserved categories but also introduces the contentious creamy layer principle for SC/ST communities, marking a paradigmatic shift in India’s approach to social justice and distributive equity. scobserver scconline

Constitutional Architecture of Reservation

Foundational Provisions: Articles 14, 15, and 16

The constitutional framework for reservations rests on the fundamental principles of equality enshrined in Articles 14, 15, and 16, which collectively establish both the right to equality and the state’s power to make special provisions for backward classes.

Article 14 – Equality Before Law:

  • Permits reasonable classification based on intelligible differentia and rational nexus
  • Recognizes substantive equality over formal equality
  • Allows sub-classification within existing classes if they are heterogeneous
  • Chief Justice Chandrachud emphasized that “equality does not entail sameness” but requires “parity of treatment under parity of conditions”

Article 15 – Prohibition of Discrimination:

  • Article 15(4) empowers the state to make special provisions for socially and educationally backward classes
  • Article 15(5) extends reservation to private educational institutions
  • Provides the constitutional basis for affirmative action in education and employment

Article 16 – Equality of Opportunity:

  • Article 16(4) enables reservation for backward classes in public employment
  • Article 16(4A) specifically addresses SC/ST reservation in promotions
  • Article 16(4B) allows consequential seniority for promoted SC/ST employees dopt.gov

Presidential Powers: Articles 341 and 342

Articles 341 and 342 vest the President of India with exclusive power to notify SC/ST lists, creating a centralized mechanism for community identification while allowing states legislative power for sub-classification.

Article 341 – Scheduled Castes:

  • President’s exclusive power to specify SC lists for each state/UT
  • Parliament’s authority to modify the lists through legislation
  • States cannot alter the Presidential list but can sub-classify within it
  • The 2024 judgment clarifies that sub-classification “does not amount to tinkering” with the Presidential list

Article 342 – Scheduled Tribes:

  • Similar framework as Article 341 for ST communities
  • Consultation with state governors for initial notification
  • Parliamentary procedure for subsequent modifications
  • Tribal characteristics and geographical considerations inform the listing process

Institutional Safeguards: Articles 338 and 338A

National Commissions serve as constitutional watchdogs for SC/ST welfare and rights protection:

National Commission for Scheduled Castes (Article 338):

  • Constitutional status with quasi-judicial powers
  • Investigation and monitoring functions for SC welfare
  • Advisory role to government on policy matters
  • Annual reporting to President on community status

National Commission for Scheduled Tribes (Article 338A):

  • Separate constitutional entity recognizing ST distinct needs
  • Parallel functions to NCSC for tribal communities
  • Special focus on tribal land rights and cultural preservation
  • Coordination mechanism between Centre and states

Historical Evolution of Reservation Jurisprudence

Indra Sawhney (1992): The Foundational Framework

The Indra Sawhney v. Union of India judgment by a 9-judge Constitution Bench established the fundamental principles governing India’s reservation system, creating a jurisprudential foundation that continues to influence contemporary decisions.

Key Indra Sawhney Principles:

  • 50% ceiling rule: Overall reservation cannot exceed 50% of total opportunities
  • Creamy layer exclusionEconomically advanced OBC members excluded from benefits
  • Backward class identificationSocial, educational, and economic backwardness as criteria
  • No reservation in promotionsPromotional quota not constitutionally mandated
  • SC/ST exclusionCreamy layer principle explicitly not applicable to SC/ST communities

Constitutional Interpretation:
The judgment recognized “backward class of citizens” as a generic term encompassing SC, ST, and OBC, while maintaining distinct treatment for each category based on their specific historical experiences and constitutional provisions.

E.V. Chinnaiah (2004): The Homogeneity Doctrine

The E.V. Chinnaiah v. State of Andhra Pradesh decision by a 5-judge Constitution Bench established the “homogeneous class doctrine” that prohibited sub-classification within SC/ST categories for two decades. cjp

Chinnaiah Holdings:

  • SCs form homogeneous class: All SC communities deemed equally backward by virtue of Presidential notification
  • No state interferenceSub-classification amounts to tinkering with Presidential list under Article 341
  • Article 14 violationPreferential treatment within SCs creates impermissible micro-classification
  • Indra Sawhney distinctionOBC sub-classification permitted but not applicable to SC/ST

Constitutional Reasoning:
The judgment emphasized that Presidential lists under Articles 341/342 create constitutionally recognized classes that states cannot fragment through legislation, maintaining the integral character of SC/ST categories. clrp

Jarnail Singh (2018): Creamy Layer Extension

The Jarnail Singh v. Lachhmi Narain Gupta judgment by a 5-judge Constitution Bench controversially extended the creamy layer principle to SC/ST promotional reservations, overturning established precedent.

Jarnail Singh Innovations:

  • Creamy layer for SC/STEconomically advanced members excluded from promotional benefits
  • Data requirementQuantifiable evidence of backwardness and inadequate representation tscld
  • Article 335 complianceAdministrative efficiency considerations in reservation policy
  • Judicial oversightCourt’s power to determine creamy layer criteria

The 2024 Paradigm Shift: Davinder Singh Judgment

Overruling Chinnaiah: Heterogeneity Recognition

The 2024 Supreme Court decision in State of Punjab v. Davinder Singh represents a fundamental reconceptualization of SC/ST categories from homogeneous groups to heterogeneous collections requiring differentiated treatment.

Majority Opinion Framework (Chief Justice Chandrachud):

  • Historical evidenceEmpirical data demonstrates SC/ST communities are not homogeneous
  • Constitutional permissibilitySub-classification allowed under Articles 14, 15, and 16
  • State legislative powerSub-classification does not tamper with Presidential lists
  • Judicial reviewAll sub-classification laws subject to constitutional scrutiny

Limitations and Safeguards:

  • No 100% allocationComplete reservation for sub-groups prohibited
  • Empirical basisData-driven justification required for sub-classification
  • Proportionate representationAll sub-groups must receive adequate opportunity
  • Periodic reviewDynamic assessment of representation patterns

Creamy Layer Controversy: Judicial Overreach?

Four of the seven judges in the 2024 judgment advocated applying creamy layer exclusion to SC/ST communities, generating significant controversy and criticism from social justice advocates.

Justice Gavai’s Creamy Layer Argument:

  • Different criteriaSC/ST creamy layer distinct from OBC parameters
  • Constitutional mandateArticle 16(1) requires genuine backward class identification
  • Resource optimizationBenefits reaching truly disadvantaged members
  • Precedential supportJarnail Singh judgment established the principle

Critical Perspectives:
Retired Judge Anil Vaidya and other legal scholars argue that creamy layer application to SC/ST communities contradicts Dr. Ambedkar’s constitutional vision and the unique nature of caste-based discrimination, which differs fundamentally from economic backwardness.


Federalism and State Policy Space

Centre-State Dynamics in Reservation Policy

The 2024 judgment significantly enhances state power in reservation policy while maintaining Central control over community identification:

State Powers Enhanced:

  • Sub-classification authorityInternal quota design within reserved categories
  • Policy experimentationDifferent approaches based on local conditions
  • Democratic accountabilityState-level political processes determining sub-group treatment
  • Administrative flexibilityImplementation strategies adapted to regional needs

Central Authority Retained:

  • Community identificationPresidential notification of SC/ST lists remains exclusive
  • Constitutional oversightSupreme Court review of state policies
  • National standardsFundamental principles applicable across states
  • Inter-state mobilityUniform recognition of reserved category status

Implementation Challenges: Telangana’s Pioneer Approach

Telangana became the first state to implement SC sub-classification following the 2024 judgment, creating separate quotas within its 15% SC reservation:

Telangana Model:

  • Sub-group AMala, Madiga, Relli, and other specified castes
  • Sub-group BMadiga community with separate allocation
  • Sub-group CRemaining SC communities
  • Sub-group DNew entrants and converts

Social Justice versus Merit Debate

Fragmentation Concerns

Critics argue that sub-classification creates fragmentation within already marginalized communities, potentially weakening collective solidarity and political mobilization:

Fragmentation Arguments:

  • “Divide within the oppressed”Inter-caste competition replacing collective struggle
  • Political manipulationElectoral calculations driving sub-classification decisions
  • Resource dilutionLimited opportunities creating zero-sum competition
  • Identity reinforcementCaste hierarchies strengthened rather than dismantled

Equity and Targeted Justice

Supporters contend that sub-classification enhances equity by ensuring benefits reach the most disadvantaged within reserved categories:

Equity Arguments:

  • Empirical evidenceData shows disproportionate benefit capture by dominant SC/ST groups
  • Constitutional mandateSubstantive equality requires differentiated treatment
  • Resource optimizationTargeted intervention more effective than blanket policies
  • Democratic legitimacyState governments accountable to affected communities

Implementation Challenges and Data Requirements

Caste Census and Empirical Foundation

Effective sub-classification requires comprehensive data collection, raising the politically sensitive issue of caste census:

Data Requirements:

  • Population proportionsDemographic distribution of sub-groups within SC/ST categories
  • Representation analysisEmployment and education participation rates
  • Socio-economic indicatorsIncome, assets, and occupation patterns
  • Historical trendsLong-term participation patterns in reserved opportunities

Political Sensitivities:

  • Caste census debateNational-level resistance to detailed caste enumeration
  • Privacy concernsIndividual and community data protection issues
  • Political implicationsElectoral calculations influencing data collection and usage
  • Administrative capacityState machinery capability for comprehensive data gathering

Criteria Development and Litigation Risk

Determining “more backward” sub-groups requires clear, defensible criteria to minimize legal challenges:

Potential Criteria:

  • Socio-educational indicatorsLiteracy rates, educational attainment, professional representation
  • Economic parametersIncome levels, asset ownership, occupational patterns
  • Political representationParticipation in elected bodies and leadership positions
  • Historical discriminationDocumented evidence of specific disadvantages

Comparative Global Perspectives

International Affirmative Action Models

India’s sub-classification approach is unique globally, as most countries with affirmative action programs maintain broader categorical classifications:

United States Model:

  • Race-based affirmative action without internal sub-classification
  • Recent Supreme Court decisions restricting race-conscious admissions
  • Socio-economic factors increasingly important in policy design
  • Individual rather than group focus in implementation

South African Approach:

  • Post-apartheid redress through broad racial categories
  • Employment equity and Black Economic Empowerment programs
  • No sub-classification within previously disadvantaged groups
  • Sunset clauses and periodic review mechanisms

Brazilian Experience:

  • Racial quotas in higher education and public employment
  • Self-identification rather than administrative classification
  • Social mobility and educational outcomes as success measures
  • Controversy over effectiveness and social impacts

Ethical Dimensions and Philosophical Debates

Equality versus Equity Paradigm

The sub-classification debate reflects deeper philosophical tensions between formal equality and substantive equity:

Formal Equality Perspective:

  • Equal treatment for all members of recognized backward classes
  • Non-discrimination within constitutionally identified groups
  • Uniform application of reservation benefits across categories
  • Legal consistency and predictable policy frameworks

Substantive Equity Approach:

  • Differentiated treatment based on actual disadvantage levels
  • Targeted intervention for most marginalized sub-groups
  • Outcomes-focused rather than process-oriented policies
  • Adaptive strategies responding to empirical evidence

Balancing Justice Claims

The ethical challenge lies in balancing competing justice claims within marginalized communities:

Distributive Justice Questions:

  • Resource allocation among differently situated but similarly backward groups
  • Historical injustice versus contemporary disadvantage in benefit distribution
  • Individual merit versus group representation in opportunity allocation
  • Intergenerational equity in affirmative action design and implementation

Way Forward: Building Inclusive Framework

National Policy Framework Development

Creating a coherent national framework for sub-classification requires multi-stakeholder consultation and evidence-based policy design:

Framework Elements:

  • Standardized criteriaUniform parameters for assessing relative backwardness
  • Data collection protocolsSystematic information gathering mechanisms across states
  • Review mechanismsPeriodic assessment of policy effectiveness and community progress
  • Inter-state coordinationCommon standards while allowing local flexibility

Strengthening Empirical Research

Robust research infrastructure is essential for informed policy decisions on sub-classification:

Research Priorities:

  • Longitudinal studiesLong-term impact assessment of reservation policies
  • Comparative analysisCross-state comparison of different approaches
  • Socio-economic surveysDetailed community profiles and progress indicators
  • Policy evaluationCost-benefit analysis of various intervention models

Democratic Deliberation and Consensus Building

Sustainable sub-classification policies require broad social consensus and democratic legitimacy:

Consultation Processes:

  • Community dialoguesAffected group participation in policy formulation
  • Expert committeesTechnical expertise informing political decisions
  • Parliamentary debateLegislative scrutiny of sub-classification proposals
  • Civil society engagementAcademic and activist input in policy design

Conclusion: Navigating Complex Terrain

The 2024 Supreme Court judgment on SC/ST sub-classification opens new possibilities for targeted social justice while creating complex implementation challenges. The tension between unity and differentiation within marginalized communities reflects broader questions about the evolution of India’s affirmative action system in a changing social landscape.

Success in implementing sub-classification will depend on careful balance between empirical rigor and political sensitivityconstitutional principles and practical needsindividual advancement and community solidarity. The journey from Chinnaiah to Davinder Singh represents not just legal evolution but a maturing understanding of how formal equality must adapt to serve substantive justice goals.

As states begin implementing sub-classification policies, the true test will be whether these new frameworks enhance social justice without fragmenting collective solidarity among India’s historically marginalized communities. The ongoing debate about creamy layer application to SC/ST categories will likely require further judicial clarification and social consensus to resolve fundamental questions about the nature and purpose of affirmative action in contemporary India.
