Constitutional Law
Right to Equality under Articles 14 to 18
Understand equality before law, classification, arbitrariness, discrimination, affirmative action, public employment, untouchability and titles.
The short answer
Constitutional equality requires fair treatment, permits justified differentiation and supports measures that address real disadvantage.
Article 14: equality and non-arbitrariness
Article 14 protects every person through equality before law and equal protection of laws.
Reasonable classification
A classification needs an intelligible differentia and a rational relation between that differentia and the law's objective. Different treatment is not forbidden when the distinction is constitutionally relevant.
Arbitrariness
State action may also fail where it is capricious, irrational or unsupported by a fair standard. Equality is opposed to arbitrary power, not confined to comparison between groups.
Substantive equality
Treating differently situated people identically can preserve disadvantage. The Constitution therefore permits targeted measures designed to create meaningful equality.
Proportionality and justification
Where State action burdens rights, courts increasingly examine the legitimacy of the aim, rational connection, necessity and balance rather than accepting a bare assertion of policy.
The specific equality guarantees
Articles 15 to 18 address recurring forms of status hierarchy and public exclusion.
Article 15
It prohibits specified discrimination and also authorises special provisions for women, children, socially and educationally backward classes, Scheduled Castes, Scheduled Tribes and economically weaker sections within the constitutional text.
Article 16
It guarantees equality of opportunity in public employment while permitting constitutionally structured reservation and related measures for represented groups.
Articles 17 and 18
Article 17 abolishes untouchability and directly condemns its practice. Article 18 abolishes specified titles while preserving military and academic distinctions.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
E.P. Royappa v. State of Tamil Nadu
(1974) 4 SCC 3
Facts: A senior civil servant challenged transfer from the post of Chief Secretary and alleged arbitrary treatment by the State government.
Legal question: Is Article 14 confined to laws that expressly classify people into groups?
Held: Equality and arbitrariness are opposed, so irrational State action can violate Article 14 even beyond the traditional classification formula.
Reasoning: No. Equality and arbitrariness are opposed, so irrational or capricious State action may violate Article 14 without a conventional classification.
Why it matters: Use it to move from classification review to non-arbitrariness.
Read the judgmentIndra Sawhney v. Union of India
1992 Supp (3) SCC 217
Facts: The implementation of reservation for Other Backward Classes in Union services led a nine-judge Bench to examine equality and affirmative action.
Legal question: How does reservation fit within equality of opportunity under Article 16?
Held: The Court upheld reservation for Other Backward Classes while structuring principles concerning backwardness, creamy layer and the general reservation ceiling.
Reasoning: The Court upheld OBC reservation while developing rules on backwardness, creamy layer and the general ceiling, treating affirmative action as a means of substantive equality.
Why it matters: Use it for substantive equality and the constitutional design of public-employment reservation.

Questions students ask
Does Article 14 prohibit every classification?
No. It prohibits class legislation and unjustified differentiation. A classification may stand where its basis is intelligible and rationally connected to the law's objective.
Is reservation an exception to equality?
Reservation is better understood as part of substantive equality within the enabling provisions of Articles 15 and 16, subject to their constitutional requirements.
