Article 21

The framers of the Constitution wanted to protect individuals from arbitrary arrest, detention, or harm by the state, drawing on ideas from due process protections in other democracies while choosing the phrase 'procedure established by law' instead of 'due process of law' used in the US Constitution. Initially this was read narrowly to mean any procedure enacted by a valid law was enough, but over time courts expanded it to ensure such procedures must also be fair, just, and reasonable, effectively building in a due-process-like protection.

In A.K. Gopalan v. State of Madras (1950), the Supreme Court initially held that 'procedure established by law' only required a validly enacted law, regardless of its fairness. This changed dramatically in Maneka Gandhi v. Union of India (1978), where the Court ruled that any procedure depriving a person of life or liberty must be fair, just, and reasonable, linking Article 21 with Articles 14 and 19. Since then, courts have used Article 21 to recognize a wide range of unenumerated rights, including the right to privacy (K.S. Puttaswamy v. Union of India, 2017), right to livelihood, right to a clean environment, right to health, and right to dignity, treating Article 21 as the heart of fundamental rights jurisprudence.

• Myth: Article 21 only protects Indian citizens.
  Fact: Courts have held that Article 21 protects 'any person,' including foreign nationals, not just citizens.
• Myth: As long as there's some law, the government can do anything under Article 21.
  Fact: Since Maneka Gandhi v. Union of India (1978), courts require that any law or procedure affecting life or liberty must also be fair, just, and reasonable—not just technically valid.
• Myth: Article 21 only protects against physical imprisonment.
  Fact: Courts have expanded it to cover rights like privacy, livelihood, health, clean environment, and dignity, treating 'life' as more than mere survival.
