Article 21: The Heart of the Indian Constitution — Expanding Horizons of Right to Life

Article 21 of the Constitution of India declares: "No person shall be deprived of his life or personal liberty except according to procedure established by law."

This seemingly simple provision has been interpreted by the Supreme Court as the most dynamic and expansive fundamental right.

Original Interpretation
In A.K. Gopalan v. State of Madras (1950), the Supreme Court gave a narrow interpretation, holding that "procedure established by law" meant any law enacted by the legislature.

The Transformative Shift: Maneka Gandhi Case
In Maneka Gandhi v. Union of India (1978), the Supreme Court revolutionised Article 21 by holding that:

• Right to life is not merely animal existence

• Procedure must be "fair, just and reasonable"

• Article 21 must be read with Articles 14 and 19

Expanded Scope of Article 21
Through judicial interpretation, Article 21 now encompasses:

• Right to livelihood (Olga Tellis case)

• Right to education (Unni Krishnan case → Article 21A)

• Right to health and medical care

• Right to clean environment

• Right to privacy (Justice K.S. Puttaswamy case — 9-judge bench)

• Right to shelter and housing

• Right to food and nutrition

• Right to travel abroad

• Right to die with dignity (Aruna Shanbaug case — passive euthanasia)

• Right to free legal aid

• Right against delayed trial

• Right to reputation

• Right to sleep
