Article 21 says: “No person shall be deprived of his life or personal liberty except according to procedure established by law.”
So it protects (i) life and (ii) personal liberty, and it limits the State: it can interfere only by a valid law + a fair procedure.
Over time, the Supreme Court has read “life” to mean life with human dignity, and “procedure” to mean fair, just and reasonable procedure (not arbitrary).
Nature and scope of Article 21 #
1) “Procedure established by law” → must be fair (Golden Triangle Test) #
Maneka Gandhi v. Union of India (1978)
Facts: Maneka Gandhi’s passport was impounded under the Passport Act; she was not given proper reasons/opportunity.
Issue: Can the State curtail personal liberty by any procedure written in law, even if unfair?
Held: No. The “procedure” under Article 21 must be fair, just and reasonable—not arbitrary or oppressive. Also, Articles 14, 19 and 21 are interlinked (the “golden triangle”).
Principle: Any law depriving life/liberty must satisfy fair procedure + non-arbitrariness.
(This is usually treated as the single most important turning point for Article 21.)
Landmark case laws on “Life” and “Personal Liberty” (chronological and exam-friendly) #
2) Early narrow approach (for background) #
A.K. Gopalan v. State of Madras (1950)
Core point: The Court initially took a narrow view—each Fundamental Right was treated somewhat separately; “procedure established by law” was read more formally.
(Later constitutional thinking moved away from this, especially after Maneka.)
3) Personal liberty includes freedom from illegal surveillance / intrusion #
Kharak Singh v. State of U.P. (1962)
Facts: Police “domiciliary visits” and surveillance of the petitioner.
Issue: Do such intrusive measures violate personal liberty?
Held: Physical intrusion like domiciliary visits was held unconstitutional as violating personal liberty.
4) Life means more than mere animal existence (dignity) #
Francis Coralie Mullin v. Administrator, Union Territory of Delhi (1981)
Facts/Issue: Conditions and restrictions affecting a detenue’s life and dignity.
Held: “Life” includes living with dignity, not mere existence (a foundation for many later rights under Article 21).
5) Right to livelihood as part of right to life #
Olga Tellis v. Bombay Municipal Corporation (1985)
Facts: Pavement/slum dwellers challenged eviction/removal which would destroy their means of survival.
Issue: Does Article 21 include livelihood?
Held: Yes. Right to life includes the right to livelihood, since without livelihood life itself becomes impossible.
6) Protection against custodial violence and illegal arrest practices #
D.K. Basu v. State of West Bengal (1997)
Facts: Concern over custodial torture/deaths; Court treated it as a constitutional crisis of rights.
Issue: What safeguards are required to protect Article 21 (and Article 22) during arrest/detention?
Held: Custodial violence violates Article 21; the Court laid down detailed arrest/detention guidelines to prevent abuse.
7) Privacy as part of life and personal liberty #
Justice K.S. Puttaswamy (Retd.) v. Union of India (Privacy) (2017)
Facts: Challenge to Aadhaar-related privacy concerns led to a reference to a larger bench.
Issue: Is privacy a Fundamental Right?
Held: Yes. Privacy is part of Fundamental Rights and is traceable to Articles 14, 19 and 21.
End-of-life, “right to die”, and euthanasia under Article 21 #
8) Aruna Ramachandra Shanbaug v. Union of India (2011) #
Bench: Justice Markandey Katju and Justice Gyan Sudha Misra.
Facts: Aruna Shanbaug was in a persistent vegetative state for decades after a brutal assault. A writ petition sought permission for euthanasia.
Issue: Whether passive euthanasia (withdrawal of life support) can be permitted in India under Article 21.
Held: The Court did not allow active euthanasia, but it recognized that passive euthanasia could be permitted in appropriate cases under strict safeguards, and directed that such permission should be taken (as per the framework then laid down) through the High Court process with medical evaluation.
Key takeaway for exams: Article 21 protects dignity, but end-of-life decisions require strict procedural safeguards to prevent misuse.
9) Later constitutional confirmation #
Common Cause (A Regd. Society) v. Union of India (2018)
Core: The Court dealt with right to die with dignity, and laid down an enforceable framework (including living wills/advance directives) with safeguards.
Conclusion #
Article 21 has grown from a narrow guarantee into the Constitution’s strongest shield for human dignity. After Maneka Gandhi, no deprivation of life or liberty is valid unless it follows a fair, just and reasonable procedure, and modern cases show that Article 21 covers essential conditions of a dignified life—livelihood, privacy, protection from custodial abuse, and even carefully safeguarded end-of-life autonomy (as seen in Aruna Shanbaug, decided by a Bench including Justice Markandey Katju).
