Right to Life

The right to life and personal liberty, guaranteed by Article 21 of the Constitution of India, has been transformed through judicial interpretation from a narrow protection against arbitrary deprivation of life and liberty into the most expansive fundamental right in the Constitution — encompassing the right to live with human dignity, the right to livelihood, the right to health, the right to education, the right to a clean environment, the right to privacy, and the right to a speedy trial, among dozens of other derived rights. It is the constitutional provision that has done the most work in advancing social justice in India through judicial activism.

The original Article 21 reads: 'No person shall be deprived of his life or personal liberty except according to procedure established by law.' For the first three decades after the Constitution came into force, the Supreme Court interpreted this provision narrowly — following the American procedural due process standard, it held that 'procedure established by law' meant any procedure prescribed by valid law, without requiring that the procedure be fair, just, or reasonable. This narrow view was definitively overturned in Maneka Gandhi v. Union of India (1978), which held that the procedure established by law affecting life or liberty must be 'fair, just, and reasonable' — importing substantive due process into Article 21.

The expansion of Article 21 through Supreme Court decisions has been extraordinary. Among the many rights derived from Article 21 by judicial interpretation: (1) right to livelihood (Olga Tellis v. Bombay Municipal Corporation, 1985 — pavement dwellers cannot be evicted without notice and rehabilitation); (2) right to health (Paschim Banga Khet Mazdoor Samity v. State of West Bengal, 1996 — State hospitals cannot refuse emergency medical treatment); (3) right to education (J.P. Unnikrishnan v. State of Andhra Pradesh, 1993 — education up to age 14 is a fundamental right; now expressly guaranteed by Article 21A); (4) right to privacy (Justice K.S. Puttaswamy v. Union of India, 2017 — privacy is a fundamental right under Articles 14, 19, and 21); and (5) right to a speedy trial (Hussainara Khatoon v. State of Bihar, 1979).

The non-suspendability of Article 21 — even during a proclaimed Emergency — was established by the 44th Constitutional Amendment (1978), in direct response to the ADM Jabalpur case (1976) where the Supreme Court majority had held that the right to life was suspended during the Emergency, allowing the detention of persons without any judicial remedy. Justice H.R. Khanna's famous lone dissent in ADM Jabalpur — that the right to life is inviolable even during Emergency — was vindicated by the 44th Amendment, which made Articles 20 and 21 non-suspendable under Article 359.

For advocates and litigants, Article 21 is the most versatile constitutional provision available. When a fundamental right is being violated and no other specific Article is clearly applicable, Article 21 — in its expansive interpretation — provides the constitutional anchor. Social rights (health, shelter, food, education), environmental rights (clean air, clean water), procedural rights (fair trial, legal aid), and privacy rights are all derived from Article 21 through judicial interpretation. Writ petitions based on Article 21 have been the vehicle for some of the most important social reforms achieved through public interest litigation.
