Life and personal liberty

1. Constitutional foundation and scope

Article 21 appears in Part III of the Constitution. Its wording imposes a restraint on State power: deprivation of life or personal liberty requires legal authority and constitutionally valid procedure. Executive convenience, an unsupported police direction or administrative discretion cannot independently justify taking away liberty. The protection belongs to every person within its constitutional reach, including foreign nationals, although foreigners do not thereby acquire citizens’ rights to reside and settle in India under Article 19.

Life means more than biological survival. Judicial interpretation connects it with human dignity and the basic conditions needed to live meaningfully. Personal liberty includes a broad range of freedoms concerning bodily integrity, movement, intimate choices and autonomy. However, Article 21 does not make every preferred activity a fundamental right, nor does it prohibit imprisonment, lawful regulation or all forms of compulsory State action.

Article 21 operates alongside other guarantees. Article 14 prohibits arbitrary State action, Article 19 protects specified freedoms of citizens, Article 20 supplies protections in criminal matters, and Article 22 addresses arrest and detention. Articles 32 and 226 provide constitutional remedies. Article 21 is principally enforceable against the State, but courts also recognise positive State duties to protect life and liberty against threats arising from private actors.

• Article 32: approach the Supreme Court for enforcement of fundamental rights.
• Article 226: High Courts may issue writs for fundamental rights and for other legal purposes.
• Habeas corpus tests the legality of detention and may also address unlawful private confinement.

2. From formal legality to fair procedure

In A.K. Gopalan v. State of Madras (1950), the Supreme Court adopted a restrictive approach to personal liberty and largely treated different fundamental rights as separate compartments. Procedure established by law was understood primarily through the existence of enacted law, rather than the broad American conception of due process. This approach left comparatively limited space for testing the fairness of a law depriving liberty.

R.C. Cooper v. Union of India (1970), the bank nationalisation case, weakened the compartmentalised approach by emphasising the effect of State action on rights. In Maneka Gandhi v. Union of India (1978), arising from the impounding of a passport, the Court held that the procedure under Article 21 must be right, just and fair. A law affecting personal liberty must satisfy Article 14 and, where applicable, Article 19 as well.

The constitutional text still says procedure established by law, not due process of law. Nevertheless, judicial review now examines fairness and non-arbitrariness, bringing substantive due-process reasoning into Indian constitutional law. Parliament cannot validate arbitrary deprivation merely by prescribing it in legislation. Equally, courts do not invalidate a policy simply because another policy appears preferable; a constitutional violation must be established.

The Emergency experience sharpened these safeguards. ADM Jabalpur v. Shivkant Shukla (1976) notoriously denied effective habeas corpus relief in the circumstances of the Emergency suspension order. The Forty-fourth Amendment subsequently insulated enforcement of Articles 20 and 21 from suspension under Article 359. The Supreme Court expressly repudiated ADM Jabalpur in the 2017 privacy judgment.

• Exam distinction: Article 358 concerns Article 19; Article 359 concerns suspension of the right to move courts for enforcement of specified rights.
• Protection from suspension does not make Article 21 absolute: lawful deprivation remains possible under constitutionally valid safeguards.

3. Dignity and the expanded meaning of life

The Court has derived several protections from dignified life. Francis Coralie Mullin v. Administrator, Union Territory of Delhi (1981) linked life with dignity and basic necessities. Olga Tellis v. Bombay Municipal Corporation (1985) recognised livelihood as part of life, while not granting an unconditional right to occupy public pavements. Rights recognition must therefore be distinguished from immunity against all regulation or eviction.

Health and environmental protection are important dimensions. In Paschim Banga Khet Mazdoor Samity v. State of West Bengal (1996), failure of government hospitals to provide timely treatment implicated Article 21. Parmanand Katara v. Union of India (1989) stressed immediate medical assistance to preserve life without allowing procedural formalities to obstruct treatment. Subhash Kumar v. State of Bihar (1991) recognised enjoyment of pollution-free water and air within Article 21.

Education illustrates the relationship between interpretation and amendment. Unni Krishnan v. State of Andhra Pradesh (1993) recognised an educational entitlement under Article 21, particularly up to age fourteen. The Eighty-sixth Amendment Act, 2002 inserted Article 21A, requiring free and compulsory education for children aged six to fourteen in the manner determined by law. The Right of Children to Free and Compulsory Education Act, 2009 operationalises this guarantee.

Directive Principles help interpret these obligations without automatically becoming independently enforceable fundamental rights. Articles 39A, 41, 42 and 47 inform legal aid, public assistance, humane working conditions and public health. Duties under Article 51A, such as environmental protection, complement rights but do not authorise the State to bypass constitutional safeguards.

• Article 21A covers ages six to fourteen, not all children below eighteen.
• Article 45 concerns early childhood care and education for children below six.
• Article 51A(k) places an educational duty on a parent or guardian concerning children aged six to fourteen.

4. Privacy, autonomy and end-of-life choices

In Justice K.S. Puttaswamy v. Union of India (2017), a unanimous nine-judge bench recognised privacy as a fundamental right protected through Article 21 and the freedoms and guarantees of Part III. Privacy includes bodily integrity, decisional autonomy and informational privacy. Restrictions require constitutional justification, including legality, a legitimate State aim and proportionality, with safeguards against abuse.

Autonomy jurisprudence protects deeply personal choices. Shafin Jahan v. Asokan K.M. (2018) affirmed the freedom of an adult to choose a spouse. Navtej Singh Johar v. Union of India (2018) decriminalised consensual sexual relations between adults insofar as Section 377 of the Indian Penal Code criminalised such conduct. Such rulings protect dignity and choice; they should not be treated as automatically deciding every distinct question of family law.

Article 21 does not establish a general right to die. Gian Kaur v. State of Punjab (1996) rejected that proposition while distinguishing dignified dying. Common Cause v. Union of India (2018) recognised advance medical directives and permitted withholding or withdrawal of life-sustaining treatment under safeguards. The Court simplified these procedures in 2023. This is distinct from legalising active euthanasia or an unrestricted entitlement to assisted death.

• Privacy is neither confined to secrecy nor limited to the home.
• Consent, dignity and autonomy are central, but restrictions and competing rights require constitutional assessment.

5. Arrest, detention and criminal justice

Article 21 protects accused persons and prisoners as well as people outside custody. The Hussainara Khatoon cases (1979) made speedy trial central to fair criminal procedure and exposed prolonged incarceration of undertrial prisoners. Free legal assistance for indigent accused is supported by Article 21 read with Article 39A. In D.K. Basu v. State of West Bengal (1997), the Court prescribed arrest and custody safeguards to prevent abuse.

Under Article 22, an ordinarily arrested person must be informed of the grounds of arrest, be allowed consultation and defence by a legal practitioner, and be produced before the nearest magistrate within twenty-four hours, excluding necessary travel time. Detention beyond that period requires magistrate’s authority. Article 22(3) excludes enemy aliens and persons detained under preventive-detention laws from these particular guarantees; preventive detention instead attracts the special safeguards of Article 22(4)–(7).

Preventive detention seeks to prevent anticipated conduct rather than punish a proved offence. Under the operative constitutional framework, detention beyond three months ordinarily requires the prescribed Advisory Board process, subject to Article 22’s provisions. The Forty-fourth Amendment’s proposed substitution of two months has not been brought into force. Courts can review detention for constitutional and statutory defects, including procedural violations and mala fides.

The death penalty has not been declared unconstitutional. Bachan Singh v. State of Punjab (1980) upheld it while requiring the rarest-of-rare standard. Custodial torture and unlawful killing cannot be justified as efficient policing. Nilabati Behera v. State of Orissa (1993) affirmed public-law compensation for violation of fundamental rights in a custodial-death case.

• Punitive detention follows criminal-law processes; preventive detention rests on a legally regulated preventive assessment.
• Prisoners retain fundamental rights except to the extent lawfully restricted by incarceration.
