Article 21: Right to Life and Personal Liberty Explained

Read this in Hindi: हिंदी में पढ़ें

Article 21 of the Constitution of India says that “No person shall be deprived of his life or personal liberty except according to procedure established by law.” It is the most expansively interpreted fundamental right in India: since Maneka Gandhi (1978), the procedure must be fair, just and reasonable, and “life” now means a life with dignity, covering privacy, livelihood, a clean environment, speedy trial and much more.

The text and who can claim it

Article 21 sits in Part III of the Constitution. It is a short provision of one sentence, but it carries two separate protections: protection of life, and protection of personal liberty. Both can be taken away only according to procedure established by law.

The word used is “person”, not “citizen”. So Article 21 protects everyone on Indian soil, including foreign nationals. This is different from rights such as Article 19, which are limited to citizens.

From Gopalan to Maneka: how the meaning changed

A.K. Gopalan v. State of Madras (1950)

In the first major case on Article 21, the Supreme Court gave “procedure established by law” a narrow meaning. Any procedure laid down by a validly enacted law was enough. The Court also treated each fundamental right as a separate compartment, so a preventive detention law did not have to satisfy Article 19.

ADM Jabalpur v. Shivkant Shukla (1976)

During the Emergency, a 4:1 majority held that once the President had suspended enforcement of Article 21 under Article 359, no person could approach a court for its protection, even against illegal detention. Justice H.R. Khanna dissented, holding that the right to life does not depend on the Constitution’s text alone. The majority view was later disowned: in Puttaswamy (2017), the Supreme Court said ADM Jabalpur was seriously flawed. Parliament also acted through the 44th Amendment (1978), which amended Article 359 so that enforcement of Articles 20 and 21 cannot be suspended even during an Emergency.

Maneka Gandhi v. Union of India (1978)

A seven-judge bench changed Article 21 for good. It held that the procedure must be “fair, just and reasonable”, not arbitrary or oppressive. It also held that Articles 14, 19 and 21 are not watertight compartments, so a law affecting personal liberty must also pass the tests of Articles 14 and 19. In practical terms, Maneka Gandhi read a form of due process into Article 21.

Key expansions of Article 21

After 1978, the Supreme Court read many rights into the words “life” and “personal liberty”. The most important are:

Life means more than survival

In Francis Coralie Mullin, the Court explained that life includes the bare necessities of a dignified existence: adequate nutrition, clothing, shelter, and the ability to read, write and express oneself. This “dignity” reading is the foundation for most later expansions.

Livelihood

In Olga Tellis, pavement and slum dwellers in Bombay challenged their eviction. The Court accepted that the right to life includes the right to livelihood, because no one can live without the means of living. The eviction was not struck down outright, but the Court insisted on a fair procedure.

Privacy

On 24 August 2017, a nine-judge bench in Puttaswamy unanimously held that privacy is a fundamental right protected under Article 21 and Part III as a whole. It overruled M.P. Sharma (1954) and Kharak Singh (1962) to the extent they held otherwise. Privacy has since been applied to reproductive autonomy, informational privacy and the choice of a life partner.

Dignity in death

On 9 March 2018, a five-judge bench in Common Cause recognised the right to die with dignity as part of Article 21 and gave legal force to advance medical directives (living wills). In January 2023, the Court simplified the procedure laid down in 2018.

Article 21 and Article 21A

Article 21A was inserted by the Constitution (Eighty-sixth Amendment) Act, 2002. It makes free and compulsory education for children aged 6 to 14 a fundamental right, in the manner the State determines by law. It grew directly out of the judicial reading of education into Article 21 in Unni Krishnan.

Limits of Article 21

Article 21 is not absolute. The State can deprive a person of life or liberty, for example through a death sentence or imprisonment, provided it follows a procedure established by law that is fair, just and reasonable. Rights such as privacy can be restricted if the restriction has a legal basis, serves a legitimate aim and is proportionate, as the Puttaswamy bench explained.

Exam angle

• Text-based questions: CLAT and AIBE often ask whether Article 21 is available to foreigners. Yes, because it uses “person”.
• Case-year matching: Expect matching questions such as Olga Tellis with livelihood, Puttaswamy with privacy, Common Cause with living wills, and Hussainara Khatoon with speedy trial.
• Emergency: After the 44th Amendment, Articles 20 and 21 cannot be suspended under Article 359. This is a favourite one-liner in judiciary prelims and UGC NET.
• Doctrinal shift: Judiciary mains often asks you to trace the move from Gopalan’s narrow reading to Maneka Gandhi’s “fair, just and reasonable” test.
• Article 21A: Remember the 86th Amendment, 2002, and the age group 6 to 14.
