Preventive detention requires a live-link to current necessity; stale allegations and changed circumstances can render detention unsustainable.

Preventive detention cannot be sustained where the alleged prejudicial conduct is remote in time and the live-link with the purpose of detention has broken. The HC applied the settled principle that detention depends on proximity between the act and the need for preventive action, and found that the long lapse since the alleged smuggling incident, the petitioner's exoneration in penalty proceedings, and the expiry of the passport showed no continuing practical purpose for detention. On those facts, the order had lost its utility and was quashed.

Issues: Whether the detention order under the preventive detention law was liable to be quashed on the ground that the alleged prejudicial activities were stale, the live-link with the purpose of detention had snapped, and continued detention would be futile.

Analysis: The detention related to alleged smuggling activity of July 2001, while the writ petition was decided in 2019. The Court noted that the petitioner's penalty proceedings had ended in exoneration, his passport had expired long ago, and there was no continuing practical purpose in maintaining the detention order. Applying the settled principle that preventive detention depends on proximity between the prejudicial act and the need for detention, the Court held that undue delay and absence of a continuing causal connection can break the live-link. On the facts, the long lapse of time and changed circumstances showed that the detention order had lost its utility.

Conclusion: The detention order was quashed and the petition was allowed.

Ratio Decidendi: A preventive detention order cannot be sustained where the prejudicial activity is remote in time and the causal connection between the activity and the purpose of detention has been broken, rendering continued detention an exercise in futility.
