Preventive detention: Article 22 and the National Security Act, 1980
Why in news: On 6 November 2026, the Gauhati High Court quashed an Assam land rights activist's detention under the National Security Act.

Preventive detention lets the state hold a person without trial to stop a feared act. Article 22 of the Constitution permits it with safeguards. The detenu must get written grounds and a chance to object, and an Advisory Board reviews longer custody. On 6 November 2026, the Gauhati High Court set aside one such order against an Assam activist.

Why this matters for UPSC
GS2 polity: Article 22, the Seventh Schedule and the National Security Act, 1980. Prelims asks the safeguards and lists; Mains, liberty versus security.
In short
Preventive detention is custody without trial to forestall a feared act. Article 22 permits it within safeguards; the National Security Act, 1980 is a central law using it.
Preventive detention must stay an exception: courts should insist on live, specific grounds, and Parliament should bring the 1978 safeguards into force.
Why it matters
A protester, trader or journalist can be held for up to a year without being charged or tried, even after a court has granted bail. The checks are the written grounds, the chance to object, the Advisory Board and a High Court. When those checks are loose, a detention order can become a quick way around the slower ordinary criminal process. Ordinary arrest asks whether a person committed a crime; preventive detention asks what the person might do next, which is harder to disprove. So how strictly courts read the grounds decides how much personal liberty survives a government's claim that public order or security is at risk.
Prelims pointers
- Article 22(3) withholds the arrest safeguards of clauses (1) and (2) from an enemy alien and from a person held under a preventive detention law.
- Seventh Schedule: Union List entry 9 covers detention for defence, foreign affairs or India's security; Concurrent List entry 3 covers State security, public order and essential supplies.
- Article 22(5) requires the grounds to be communicated as soon as may be; Article 22(6) lets the authority withhold facts it considers against the public interest.
- Article 22(7) lets Parliament, not the States, prescribe the maximum period, the cases of longer detention without a Board, and the Board's procedure.
- Under the NSA, grounds are severable: one invalid ground does not void an order that the remaining grounds can sustain.
- Punitive detention follows conviction for an offence after trial; preventive detention anticipates a future act and needs no charge or trial.
Practise a UPSC-style question
With reference to Article 22 of the Constitution of India, consider the following statements:
1. A person arrested under ordinary law must be produced before the nearest magistrate within 24 hours, excluding journey time.
2. The right to consult a legal practitioner of choice under Article 22(1) extends to persons held under preventive detention laws.
3. A detaining authority may withhold facts that it considers against the public interest to disclose.
Which of the statements given above is/are correct?
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Show the answer
Answer: (c) 1 and 3 only
Answer: (c) 1 and 3 only. Clause (3) removes the arrest safeguards for preventive detainees.
Statement 1: correct. Article 22(2) requires production before the nearest magistrate within 24 hours, journey time excluded.
Statement 2: incorrect. Article 22(3) says clauses (1) and (2) do not apply to a person held under a preventive detention law.
Statement 3: correct. Article 22(6) lets the authority keep back facts it considers against the public interest.
Eliminate: statement 2 is wrong, as clause (3) excludes detainees from clause (1). Out: (a), (b), (d).
Trap: Wrong scope. The lawyer right belongs to ordinary arrest; the statement stretches it to preventive detention.
Remember: Clauses (1)-(2) protect arrest; clauses (4)-(7) protect preventive detention.
