How does Article 21 of the Constitution of India protect life and personal liberty?

Article 21 of the Constitution of India guarantees that no person shall be deprived of their life or personal liberty except according to procedure established by law. While the text is brief, the Supreme Court of India has played a pivotal role in expanding its scope through landmark judicial interpretations, ensuring it serves as a robust safeguard for human dignity.12

Key aspects of this protection include:

• Broadened Interpretation: Through the ruling in Maneka Gandhi v. Union of India (1978), the court established that any law depriving a person of liberty must be "just, fair, and reasonable," effectively linking Article 21 to other fundamental rights.12
• Inclusion of Socioeconomic Rights: The judiciary has interpreted the "right to life" to encompass essential elements of human existence, including the right to privacy, livelihood, education, and legal aid.12
• Protection of Vulnerable Groups: The article has been used to secure rights for marginalized communities, such as decriminalizing same-sex relationships in Navtej Singh Johar v. Union of India (2018) and ensuring workplace safety for women.12

These judicial precedents ensure that the state remains accountable for protecting the fundamental dignity and autonomy of every individual.12
