Article 21: right to life and liberty, and how to use it
What Article 21 covers today (dignity, privacy, legal aid, health, a fair arrest), and the exact steps when someone is detained or denied a basic right.
In short
- Art 21: no person may be deprived of life or personal liberty except by a procedure established by law, and that procedure must be fair, just and reasonable.
- Courts have read into it the rights to dignity, livelihood, privacy, speedy trial, free legal aid, health, shelter and a clean environment.
- If someone is arrested, they must be told the grounds, a relative must be informed, and they must be produced before a magistrate within 24 hours (Sec 58 BNSS).
- For an illegal detention, any relative or friend can have a habeas corpus petition filed in the High Court. Free legal aid: 15100. NHRC: 14433.
Article 21 is a single sentence. Yet it is the source of many of the most important rights you have, from privacy to a speedy trial to clean air. Whenever a person is held in custody, evicted from a home, or refused medical care by the state, the legal argument usually begins here.
What the law says
Art 21 says: "No person shall be deprived of his life or personal liberty except according to procedure established by law."
It protects every person in India, citizen or not. It mainly binds the State: governments, police, municipal bodies, public hospitals and other public authorities. Its enforcement cannot be suspended even during a national emergency, after the 44th Amendment, 1978.
From a narrow start to a wide right
In A.K. Gopalan v. State of Madras (1950) the Supreme Court read the Article narrowly: if Parliament had laid down a procedure, following it was enough, fair or not.
That changed in Maneka Gandhi v. Union of India (1978). The government had impounded a passport without reasons or a hearing. The Court held that the "procedure established by law" must itself be fair, just and reasonable, and that Articles 14, 19 and 21 must be read together. From then on, Article 21 became a real check on state power.
In Francis Coralie Mullin v. Union Territory of Delhi (1981) the Court said "life" means more than animal existence: it means a life with human dignity and its bare necessities.
Rights the courts have found within Article 21
- Livelihood: Olga Tellis v. Bombay Municipal Corporation (1985). Pavement dwellers could not be evicted without a fair procedure, because eviction took away their means of living.
- Speedy trial and free legal aid: the Hussainara Khatoon cases (1979), after thousands of undertrials were found in Bihar's jails for years without trial.
- Protection in custody: D.K. Basu v. State of West Bengal (1997) laid down arrest safeguards that are now written into the BNSS.
- Privacy: Justice K.S. Puttaswamy v. Union of India (2017), a unanimous nine-judge bench.
- Dignity in dying: Common Cause v. Union of India (2018) recognised the right to refuse life support through an advance medical directive, or "living will".
- Health: in Parmanand Katara v. Union of India (1989) the Court held that every doctor, government or private, must give emergency treatment to save life without waiting for police formalities.
- Shelter, education and a clean environment have also been recognised in many judgments. Education for children aged 6 to 14 is now a separate right under Art 21A.
Liberty when you are arrested
Article 21 works with Art 22 and the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS). If you or a family member is arrested:
- Police must tell you the grounds of arrest and, if the offence is bailable, your right to bail (Sec 47 BNSS, earlier Sec 50 CrPC).
- Police must inform a relative or friend you name, and record it (Sec 48 BNSS).
- An arrest memo must be prepared and signed by a witness (Sec 36 BNSS).
- You can ask for a medical examination to record any injuries (Sec 53 BNSS).
- You must be produced before a magistrate within 24 hours, excluding travel time (Sec 58 BNSS, earlier Sec 57 CrPC).
- For offences punishable with up to seven years, police must normally issue a notice to appear instead of arresting (Sec 35 BNSS, following Arnesh Kumar v. State of Bihar, 2014).
- An undertrial who has spent half the maximum sentence in custody (one-third for a first-time offender) must be released on bail, except in offences punishable with death or life imprisonment (Sec 479 BNSS).
Step by step
- If someone is picked up by police: note the time, the officers' names or vehicle number, and the police station. Call 112 if there is a threat to safety. At the station, ask for the arrest memo and grounds in writing, and a medical examination if there are injuries.
- Get a lawyer the same day. Call 15100 or go to the District Legal Services Authority (DLSA) at the district court. Anyone in custody is entitled to a free legal aid lawyer under the Legal Services Authorities Act, 1987.
- If the person is not produced within 24 hours, or you are not told where they are: your lawyer files a habeas corpus petition in the High Court under Art 226. Any relative or friend can be the petitioner. These are heard urgently, often the same or next day.
- If a public official has caused injury or illegal detention: complain to the National or State Human Rights Commission within one year, online at hrcnet.nic.in or on 14433. No lawyer is needed, and the commission can recommend compensation.
- If you face eviction, demolition or denial of water, ration or treatment: ask for the written order and a hearing. Lodge a grievance on pgportal.gov.in, and take legal aid advice on a writ petition if the authority refuses to follow a fair procedure.
Suresh's 19-year-old son Vikas is taken from their home in Patna by men in plain clothes at 10 pm. By the next evening nobody has told the family where he is. Suresh notes the time and vehicle number, calls 112, and visits two police stations, which deny holding him. The next morning he goes to the DLSA at the civil court. A legal aid lawyer files a habeas corpus petition in the Patna High Court that afternoon. The court directs the Superintendent of Police to produce Vikas the next day. He is produced, found to have been held at an outpost beyond 24 hours, and released; the court orders an inquiry.
Keep these ready
- Time, place and details of the arrest or incident, and the names of witnesses.
- The arrest memo, FIR number or any notice or order you were given.
- Photos of injuries and the medical examination report.
- ID and address proof of the detained person; income or category proof for legal aid.
Signing a blank paper or a "confession" at the police station is the most common mistake. A confession to a police officer cannot be used against you in court, but a signed statement can still cause harm. Say politely that you will answer in the presence of your lawyer, and insist that the time of arrest be recorded correctly.
Where to go
- Emergency: 112; women 181; children 1098.
- Police hierarchy: the Station House Officer, then the Superintendent of Police or Deputy Commissioner in writing.
- Free legal aid: 15100; the DLSA at the district court; nalsa.gov.in.
- Human rights commissions: NHRC helpline 14433, hrcnet.nic.in; your State Human Rights Commission.
- Courts: habeas corpus or writ petition in the High Court (Art 226) or the Supreme Court (Art 32, sci.gov.in).
Common questions
What rights come under Article 21?
The Supreme Court has held that life and personal liberty include the right to live with dignity, livelihood, privacy, shelter, health and emergency care, a speedy trial, free legal aid, protection from custodial torture, a clean environment and the right to die with dignity. Each can be enforced against the government through a writ petition.
Can the police keep someone for more than 24 hours?
Not without a magistrate's order. Under Article 22 and Sec 58 BNSS, an arrested person must be produced before a magistrate within 24 hours, excluding travel time. Only the magistrate can authorise further custody. If the police refuse to say where a person is, or hold them longer, a habeas corpus petition in the High Court is the fastest remedy.
Does Article 21 apply to a private hospital or private company?
Article 21 binds the State, so a writ normally lies against a government body. But the Supreme Court has held that every doctor, including in private hospitals, must give emergency treatment to save life. Against a private employer or landlord, use labour law, consumer law or the civil courts; a legal aid lawyer can advise.
Who can file a habeas corpus petition?
Anyone: a parent, spouse, sibling, friend or even a stranger who knows of the detention. The detained person does not have to sign. The petition is filed in the High Court under Article 226 or the Supreme Court under Article 32, and is listed urgently. Legal aid lawyers file them free for eligible persons.
