Preventive detention review limited to some material before authority; court cannot reassess sufficiency or substitute satisfaction.

Section 10 of the Act was held to run from the date of actual detention, not from the date of the detention order, so the appeal did not become infructuous merely because the maximum detention period had expired on the contrary view. In preventive detention review under Article 226, the Court may only verify whether the detaining authority had some material before it; it cannot assess the sufficiency of that material or apply proof beyond reasonable doubt. The High Court erred in quashing the detention order, and the detention was sustained because the authority's satisfaction was based on material and judicial review was limited.

Issues: (i) Whether the appeal had become infructuous because the maximum period of detention under Section 10 of the Act had expired. (ii) Whether the High Court could quash the detention order on the ground that the material before the detaining authority was insufficient to show knowledge of smuggling activity.

Issue (i): Whether the appeal had become infructuous because the maximum period of detention under Section 10 of the Act had expired.

Analysis: Section 10 fixes the period of detention from the date of actual detention, not from the date of the detention order. Accepting the contrary view would permit a detenu to avoid detention by absconding and would also allow benefit from an invalid judicial order that had interrupted detention.

Conclusion: The preliminary objection was rejected and the appeal did not become infructuous.

Issue (ii): Whether the High Court could quash the detention order on the ground that the material before the detaining authority was insufficient to show knowledge of smuggling activity.

Analysis: In writ jurisdiction under Article 226, the Court's task is confined to seeing whether the detention order rests on some material before the detaining authority. The Court cannot test the adequacy of that material or apply the criminal standard of proof beyond reasonable doubt. The satisfaction required under Section 3 is that of the detaining authority, and not of the Court.

Conclusion: The High Court erred in quashing the detention order; the detention was sustained and the appeal was allowed.

Final Conclusion: The detention order was restored and the High Court's interference was set aside because the order was founded on material and the limited scope of judicial review in preventive detention did not permit reassessment of sufficiency of evidence.

Ratio Decidendi: In preventive detention matters, the court may only examine whether the detaining authority acted on some material; it cannot review the sufficiency of that material or substitute its own satisfaction for that of the authority.
