Constitutional Law

Right to Life and Personal Liberty under Article 21

Learn Article 21, fair procedure, dignity, privacy and the structured test for State interference with life and personal liberty.

By Advocate Aditya Sharma9 min read

Quick answer

Article 21 requires valid law and a fair, just and reasonable procedure before the State may deprive any person of life or personal liberty.

Life means more than physical survival

Article 21 protects every person and has become the constitutional home of dignity, autonomy and fair procedure.

Authority of law

Executive action cannot deprive life or liberty without law. The law must also survive other constitutional guarantees rather than merely exist on paper.

Fair, just and reasonable procedure

Maneka Gandhi rejected a narrow reading of procedure established by law. Procedure affecting liberty cannot be arbitrary, oppressive or unfair.

Articles 14, 19 and 21 together

A measure may require simultaneous review for equality, freedom and liberty. Compliance with one provision does not excuse violation of another.

Positive obligations

Article 21 can require reasonable State protection of conditions necessary for dignified life, though the precise remedy depends on text, resources, legislation and institutional competence.

Dignity, privacy and decisional autonomy

The right protects a sphere in which individuals form identity, relationships and personal choices.

Dignity

Dignity informs rights concerning humane treatment, livelihood, shelter, health, environment, legal aid and conditions of detention. Each claim still needs a concrete constitutional analysis.

Privacy

Puttaswamy recognised privacy as a Fundamental Right grounded in liberty and dignity, covering bodily, informational and decisional dimensions.

The privacy test

Interference needs legality, a legitimate State aim and proportionality, including safeguards against abuse. Privacy is protected but not absolute.

Held: Privacy is a Fundamental Right grounded in dignity and liberty, and interference requires legality, legitimate aim and proportionality.
