You Cannot Be Detained Only Because You Confessed to the Police

Preventive detention holds a person without trial, on an apprehension of future conduct rather than proof of an offence. Because it dispenses with trial, the law permits it only within strict limits.

The National Security Act, 1980 allows detention where the authorities are satisfied that a person must be prevented from acting in a manner prejudicial to security or public order. The detainee has no trial, and challenges the order through the advisory board and the constitutional courts.

In Mulla Afroz v. Union of India & Ors., Criminal Appeal No. 4310 of 2026, decided on 29 September 2026, the Supreme Court quashed a detention under the NSA connected to the 2024 Sambhal violence. The ground relied on by the authorities was, in substance, a confession made by the detenu to the police.

• A confession made to the police cannot, by itself, justify an order of preventive detention.
• There must be independent material to support the subjective satisfaction of the detaining authority.
• The detenu was directed to be released immediately.
• The State was directed to pay ₹10 lakh as costs.

A statement made in police custody is the weakest form of evidence precisely because it is made in custody. The safeguards against self-incrimination exist for that reason, and a detention order that rests on such a statement borrows none of the reliability that a trial would test.

The second concern is structural. If detention could be founded on a confession, an order of detention would become available after bail had been granted in the criminal case — turning a preventive power into a means of overriding the criminal process. The Court declined to permit that.

Preventive detention is justified by necessity, not convenience. Each of its features — no trial, no charge, no ordinary rules of evidence — is a departure from the criminal process, and each must be confined to what the statute permits.

The judgment therefore does two things at once: it decides the individual case, and it restates that the strength of the stated ground is reviewable by a court rather than a matter for the executive alone.

• Whether the material relied on is independent and capable of supporting the satisfaction recorded.
• Whether the grounds supplied are vague or do not disclose the case being met.
• Whether the representation was considered by the appropriate authority.
• Whether the detention was used to circumvent an order of bail in parallel criminal proceedings.
