Article 14 — Equality Before Law and Equal Protection of Laws
"The State shall not deny to any person equality before the law or the equal protection of the laws within the territory of India." — Article 14, Constitution of India
Article 14 contains two concepts borrowed from different legal traditions:
- "Equality before law" — from the British common law tradition. A NEGATIVE concept: no person is above the law; everyone is subject to ordinary courts; no special privileges.
- "Equal protection of the laws" — from the American 14th Amendment. A POSITIVE concept: the law treats everyone equally, but allows REASONABLE CLASSIFICATION.
The doctrine of reasonable classification
Article 14 does NOT prohibit classification — only ARBITRARY classification. A law can treat different groups differently if the classification satisfies two tests:
- Intelligible differentia: There must be a logical, identifiable basis for distinguishing those grouped together from those left out.
- Rational nexus: The classification must have a rational relationship with the objective the law seeks to achieve.
Examples: A law providing pension only to widows passes Article 14 (intelligible differentia: widowhood; rational nexus: financial vulnerability). A law providing pension only to widows from a specific district would fail (no rational nexus with the policy goal).
The expanded "non-arbitrariness" test
Beyond classification, the Supreme Court has read into Article 14 a broader principle: state action must not be arbitrary. Even a non-discriminatory law that operates arbitrarily can violate Article 14.
E.P. Royappa v. State of Tamil Nadu
Justice Bhagwati introduced the "non-arbitrariness" test: "Equality is antithetic to arbitrariness. Where an act is arbitrary, it is implicit in it that it is unequal both according to political logic and constitutional law."
Maneka Gandhi v. Union of India
Justice Bhagwati extended Royappa: "Article 14 strikes at arbitrariness in state action and ensures fairness and equality of treatment." Linked Article 14 with Articles 19 and 21 — the "golden triangle."
Article 15 — Prohibition of Discrimination
Article 15(1) prohibits the state from discriminating against any citizen on grounds only of religion, race, caste, sex, or place of birth. Note: "only" — discrimination on these grounds combined with other valid criteria may be permissible.
Article 15(2) extends the prohibition to private discrimination in access to: shops, public restaurants, hotels, places of public entertainment; wells, tanks, bathing ghats, roads, places of public resort maintained wholly or partly out of state funds.
Article 15(3) allows special provisions for women and children — reservation in education, special protection laws (e.g., POCSO Act, Maternity Benefit Act).
Article 15(4) — added by the 1st Constitutional Amendment 1951 (responding to State of Madras v. Champakam Dorairajan) — allows special provisions for socially and educationally backward classes (SEBCs), SCs, STs.
Article 15(5) — added by 93rd Amendment 2005 — extends reservation to private educational institutions (except minority institutions).
Article 15(6) — added by 103rd Amendment 2019 — allows reservation for economically weaker sections (EWS) not covered by 15(4) or 15(5).
Article 16 — Equality of Opportunity in Public Employment
Article 16(1) guarantees equality of opportunity in matters relating to public employment. Article 16(2) bars discrimination on grounds of religion, race, caste, sex, descent, place of birth, residence.
Article 16(4) — original provision — allows the state to provide reservation for any backward class which is not adequately represented.
Article 16(4A) — added by 77th Amendment 1995 — allows reservation in promotions for SCs/STs.
Article 16(4B) — added by 81st Amendment 2000 — allows the carrying forward of unfilled reserved vacancies (the "backlog" reservation).
Article 16(6) — added by 103rd Amendment 2019 — allows EWS reservation in public employment.
Article 17 — Abolition of Untouchability
Article 17 abolishes "untouchability" and forbids its practice in any form. The enforcement of any disability arising out of untouchability is an offence punishable by law.
The Constitution does not define "untouchability" — the Supreme Court has interpreted it as the practice arising from the caste system that denies certain communities access to public spaces, temples, water sources, education and equal treatment.
Statutory framework:
- Protection of Civil Rights Act 1955 (originally the Untouchability Offences Act, renamed in 1976).
- Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act 1989 ("SC/ST PoA Act") — provides for specific offences, special courts, witness protection. Amended in 2015 to strengthen provisions.
- Manual Scavengers Act 2013 — prohibits manual scavenging; mandates rehabilitation.
Despite the constitutional abolition, untouchability persists — particularly in rural India. The NCRB records over 50,000 cases under SC/ST PoA Act annually. Recent verdicts have been increasingly strict on the SC/ST PoA Act provisions; the Supreme Court in Prathvi Raj Chauhan v. Union of India (2020) upheld the 2018 amendments restoring strict provisions of the Act.
Article 18 — Abolition of Titles
Article 18 abolishes the conferment of titles by the state (military and academic distinctions are excluded). Citizens cannot accept any title from a foreign state without the consent of the President.
The provision was controversial — particularly regarding the Bharat Ratna, Padma Vibhushan, Padma Bhushan, Padma Shri. In Balaji Raghavan v. Union of India (1996), the Supreme Court held that the Padma awards are NOT "titles" within the meaning of Article 18 because they cannot be used as suffixes or prefixes to one's name. They are merely "national awards" — recognising service to the nation.
Reservation jurisprudence — seventy-five years in 8 cases
State of Madras v. Champakam Dorairajan
The Madras government issued a Communal Order reserving seats in medical and engineering colleges for various castes. SC held this violated Article 29(2). Triggered the 1st Constitutional Amendment 1951 adding Article 15(4) — explicitly permitting special provisions for backward classes.
M.R. Balaji v. State of Mysore
Mysore (now Karnataka) reserved 68% of seats for OBCs and SC/STs combined. SC held: reservation cannot exceed 50% as a general rule. First articulation of the 50% cap.
State of Kerala v. N.M. Thomas
SC held that reservation is NOT an exception to equality — it is a facet of substantive equality. This is the doctrinal foundation for treating reservation as part of, not contrary to, the equality principle.
Indra Sawhney v. Union of India (Mandal case)
9-judge bench The most consequential reservation verdict. Upheld OBC reservation (27%) recommended by Mandal Commission. Laid down: (1) 50% cap on total reservation; (2) "Creamy layer" exclusion among OBCs; (3) Reservation should be primarily caste-based; (4) Reservation does not apply to promotion. Court also barred politically-motivated identification of backward classes — required Backward Classes Commission.
M. Nagaraj v. Union of India
Upheld reservation in promotions for SC/STs (added by 77th Amendment 1995), but laid down conditions: state must demonstrate (a) backwardness, (b) inadequacy of representation, (c) effect on administrative efficiency. Modified in Jarnail Singh 2018 — removed the backwardness condition for SC/ST as constitutionally presumed.
Ashoka Kumar Thakur v. Union of India
Upheld OBC reservation in central educational institutions (Central Educational Institutions Reservation Act 2006). Applied "creamy layer" principle to OBCs in education. Held quota was a means, not an end.
Janhit Abhiyan v. Union of India (EWS)
3:2 5-judge bench upheld 10% reservation for Economically Weaker Sections (EWS) — non-SC/ST/OBC general category — added by 103rd Amendment 2019. Majority held: (1) economic criteria can be a basis for reservation; (2) 50% cap doesn't apply to EWS (which is on a different basis); (3) excluding SC/ST/OBC from EWS quota is permissible. CJI Lalit and Justice Bhat dissented.
State of Punjab v. Davinder Singh
6:1 7-judge bench HELD: States CAN sub-classify SCs and STs for purposes of reservation. The earlier E.V. Chinnaiah v. State of Andhra Pradesh (2004) — which had held SCs/STs are a homogeneous group — is OVERRULED. Sub-classification must be based on empirical data. The "creamy layer" principle may also apply to SCs/STs — opening major political debate. Justice Bela Trivedi dissented.
The EWS reservation and Janhit Abhiyan 2022
The 103rd Constitutional Amendment Act 2019 created a 10% reservation for Economically Weaker Sections (EWS) — among the general (non-SC/ST/OBC) category. To qualify:
- Annual family income below ₹8 lakh;
- Family not owning more than 5 acres of agricultural land;
- Family not owning a residential flat above 1,000 sq ft;
- Family not owning a residential plot above specified size in urban areas.
The Amendment was challenged on three grounds:
- Crossing the 50% cap: With EWS added to existing SC/ST/OBC reservation, total reservation now reaches 59.5% — exceeding the Indra Sawhney cap.
- Excluding SC/ST/OBC from EWS quota: The amendment makes EWS available only to general-category families.
- Using economic criteria alone: Departing from the constitutional tradition of caste-based reservation.
In Janhit Abhiyan (November 2022), the 5-judge bench upheld the amendment by 3:2 majority. The majority reasoning:
- The 50% cap from Indra Sawhney applies to caste-based reservations under Articles 15(4) and 16(4); economic criteria is a separate basis under newly-added 15(6) and 16(6).
- SC/ST/OBC categories have their own reservations — adding them to EWS would be "double benefit." Exclusion is reasonable classification.
- Economic disability is a legitimate basis for affirmative action even if the targeted group doesn't face caste-based disability.
The dissenting opinions (CJI U.U. Lalit and Justice Bhat) argued that introducing economic criteria as the sole basis disrupts the constitutional scheme and that the exclusion of SC/ST/OBC from EWS quota violates equality.
Sub-classification — Davinder Singh 2024
The August 2024 verdict in State of Punjab v. Davinder Singh may be the most consequential reservation verdict since Indra Sawhney. By 6:1, the 7-judge bench held:
- States CAN sub-classify SCs and STs for purposes of reservation;
- Sub-classification must be based on empirical data of relative backwardness within the SC/ST groups, not political considerations;
- The earlier E.V. Chinnaiah v. State of Andhra Pradesh (2004) — which had held that SCs/STs are a "homogeneous group" not subject to sub-classification — is OVERRULED;
- The Court suggested that the "creamy layer" principle (currently applicable to OBCs) may also be applicable to SCs/STs — though this is not a binding holding;
- States are now empowered to identify which SC/ST sub-groups are most backward and provide them preferential access within the SC/ST quota.
The political implications are substantial. Several states (Punjab, Tamil Nadu, Andhra Pradesh, Telangana) have long sought to sub-classify SCs to ensure that the most marginalised SC sub-castes get a share of reservation, rather than the better-off SC sub-castes capturing all benefits.
The "creamy layer" suggestion has sparked particular debate. SC/ST groups have argued that caste-based discrimination operates regardless of income — a high-earning Dalit doctor still faces caste discrimination. Creamy layer exclusion, they argue, would dilute the constitutional commitment to caste-based affirmative action. Counter-arguments suggest that within SC/ST quotas, advanced families are capturing benefits at the expense of the most backward.
As of 2026, the Davinder Singh principles are being operationalised by various state governments. The federal political debate over its implications is ongoing.
