Satisfaction of Detaining Authority Must Be Based on Cogent Material; Mere Ipse Dixit Can't Sustain Detention: Supreme Court

“Bail in Unrelated Case Can't Justify Detention”, In a significant ruling reasserting constitutional safeguards against arbitrary preventive detention, the Supreme Court quashed a preventive detention order passed under the Tamil Nadu Prevention of Dangerous Activities Act, 1982, against a man who was already in judicial custody. The apex court ruled that the detaining authority’s reliance on bail granted in an unrelated case to another accused, in order to infer the likelihood of release of the detenue, was not a valid basis for ordering preventive detention.

The bench comprising Justices Manoj Misra and Manmohan held that “subjective satisfaction of the detaining authority stood vitiated for lack of cogent material,” and that the “detention order was rendered illegal ab initio.”

Preventive Detention of Persons Already in Jail Requires Strict Compliance with Constitutional and Legal Safeguards

The case arose from a detention order dated February 22, 2025, passed by the District Magistrate and District Collector, Pudukkottai, under Section 3(1) of the Tamil Nadu Act 14 of 1982, against one Thiru. Ramaiah, who was already in judicial custody in connection with a murder case (Crime No. 01/2025).

While the detaining authority acknowledged in the grounds of detention that the detenue was in custody and that his bail plea had already been rejected on February 7, 2025, it proceeded to detain him on the basis of a bail granted in a different case to another person. The authority concluded that there was a real possibility that Ramaiah would also soon obtain bail and return to prejudicial activities.

Challenging this logic, the appellant (wife of the detenue) approached the Madurai Bench of the Madras High Court through a habeas corpus petition. However, the High Court dismissed the plea on October 28, 2025. The Supreme Court, in appeal, reversed that decision.

“No Bail Application Pending; No Co-Accused Released on Bail – Detention Order Unsustainable”

The central legal question before the Court was whether a preventive detention order could be validly passed against a person already in custody, in the absence of any real or imminent likelihood of their release on bail.

Referring to a consistent line of decisions starting from Rekha v. State of Tamil Nadu, (2011) 5 SCC 244, the Court reiterated the three-pronged test laid down for such cases:

“A person already in custody may be preventively detained only if three conditions are satisfied:
(i) The authority is aware that the person is in custody;
(ii) There is cogent material to show a real possibility of release on bail in the near future; and
(iii) There is a likelihood of the person engaging in prejudicial activities upon such release.”

In the present case, the Court found that although the first condition was satisfied, the second and third were clearly absent.

As observed in Paragraph 19 of the judgment:

“There is nothing on record to indicate that co-accused of the case in which the appellant was under judicial custody was admitted to bail… The detaining authority referred to some other person being admitted to bail in some other case, but did not disclose the facts of that case to demonstrate that it was so similar that a reasonable satisfaction could be drawn that detenue is likely to benefit from it and be released on bail.”

Reliance on Unrelated Bail Order Termed “Mere Ipse Dixit” – Subjective Satisfaction Vitiated

The Court took serious exception to the mechanical reliance on bail granted in a completely unrelated matter. The person granted bail (Mohanraj) was neither a co-accused nor similarly placed as Ramaiah. Citing Huidrom Konungjao Singh v. State of Manipur, (2012) 7 SCC 181, the Court emphasized:

“Merely because somebody else in similar cases had been granted bail, there could be no presumption that in the instant case had the detenu applied for bail, he could have been released.”

Justice Misra, writing for the Bench, held that such reliance lacked legal foundation:

“The detaining authority’s inference of likelihood of bail, based on an unrelated case, amounts to mere ipse dixit. In preventive detention, satisfaction must be based on specific and reliable material. A speculative satisfaction is not enough.”

Preventive Detention an Exceptional Measure – Constitutional Protections Must Be Rigorously Enforced

Reiterating the exceptional nature of preventive detention and the fundamental rights enshrined in Articles 21 and 22 of the Constitution, the Court cautioned against casual invocation of such laws:

“Preventive detention being an exceptional measure, safeguards under Articles 21 and 22 must be strictly complied with. Any casual or mechanical approach in recording satisfaction renders detention unsustainable.”

Further, referring to Rajesh Gulati v. Govt. of NCT of Delhi, (2002) 7 SCC 129, the Court noted that a later grant of bail does not cure the illegality of a detention order passed without proper material at the time of its issuance.

Supreme Court Allows Appeal, Orders Immediate Release

Finding the detention order illegal and constitutionally unsustainable, the Court allowed the appeal:

“The appeal is allowed. The impugned judgment and order of the High Court dismissing the habeas corpus petition is set aside. The detention order is hereby quashed. The appellant shall be released forthwith unless he is in custody in connection with any other case.”

The Court also clarified that its judgment did not express any opinion on the merits of the prosecution’s case in the pending criminal proceedings.
