Article 21 of the Indian Constitution, originally limited to protection against unlawful arrest, has evolved into a source of multiple fundamental rights—from privacy to livelihood, dignity, environment, education, and beyond.
📚 What Does Article 21 Say?
“No person shall be deprived of his life or personal liberty except according to procedure established by law.”
On the surface, this may sound like a procedural safeguard against arbitrary detention. But over time, judicial interpretation has turned it into the heart of fundamental rights in India.
🧱 Phase 1: Narrow Interpretation
🧑⚖️ A.K. Gopalan v. State of Madras (1950)
-
Early interpretation of Article 21 was narrow and literal.
-
The Court held that as long as there’s a “law” and procedure is followed, personal liberty can be restricted—even if the law is unjust.
-
This meant no connection between Article 21 and other rights like Article 19.
🟥 Problem: The state could pass harsh laws and still stay “within the law.”
🧱 Phase 2: Liberal Interpretation Begins
🧑⚖️ R.C. Cooper v. Union of India (1970)
-
Broke the “compartmentalization” of rights.
-
Held that fundamental rights are interconnected and cannot be read in isolation.
This laid the foundation for a more holistic approach to interpreting Article 21.
🧱 Phase 3: The Turning Point
🧑⚖️ Maneka Gandhi v. Union of India (1978)
-
A passport was seized without explanation, leading to a major legal battle.
-
The Court overruled A.K. Gopalan, and said:
“The procedure under Article 21 must be just, fair, and reasonable—not arbitrary, fanciful, or oppressive.”
✅ Connected Article 21 with Articles 14 (equality) and 19 (freedom).
✅ Established substantive due process in India.
This judgment opened the floodgates for new rights under Article 21.
🌱 Phase 4: Expansion into Implied Rights
The Supreme Court began reading new rights into Article 21, making it the source of numerous socio-economic and personal freedoms.
Key Rights Recognized Under Article 21:
