2012 · Paper III

Explain the Right to Equality guaranteed under the Constitution of India in the light of the doctrine of reasonable classification.

In short

Article 14 guarantees equality before the law and equal protection of the laws, and the doctrine of reasonable classification lets the State treat unequals differently only where an intelligible differentia has a rational nexus to the law's objective. This reconciles equality with affirmative action under Articles 15(4) and 16(4).

Model answer

Introduction
The Right to Equality, enshrined in Articles 14 to 18, prohibits arbitrary discrimination and ensures equal treatment, balanced by the doctrine of reasonable classification to address social diversity and affirmative action.
Right to Equality under the Indian Constitution
•

Constitutional Guarantee

Article 14 guarantees equality before the law and equal protection, foundational to the rule of law.

Affirmative Action Provisions

Articles 15(4) and 16(4) permit reservations for socially and educationally backward classes, SCs, and STs to promote substantive equality.

Judicial Interpretation

The Supreme Court’s allowance of sub-classification within SC/ST reservations, as applied in Andhra Pradesh, addresses backwardness and regional disparities.
