Preventive detention may rest on organised conduct from a single incident, but unexplained execution delay can vitiate the order.

A single incident may sustain preventive detention where the surrounding facts show organised conduct, advance planning, coordination and future potentiality to repeat prejudicial acts, and the order was upheld on that basis. The detenue's surrender of passport and the alleged non-placement of the cancellation-of-bail application did not vitiate subjective satisfaction, and preventive detention was held permissible even though ordinary criminal law was available, given the organised smuggling activity. However, unexplained delay in executing the detention order, despite known address details, was found to have snapped the live link between the grounds and detention, rendering the order unsustainable and the writ petition allowed.

Issues: (i) Whether the detention order could be sustained on the basis of a solitary incident; (ii) Whether the detaining authority's subjective satisfaction was vitiated by the detenue's surrender of passport and by the alleged non-placement of a vital document; (iii) Whether preventive detention was unwarranted because the ordinary law was sufficient; and (iv) Whether unexplained delay in execution of the detention order snapped the live link and invalidated the order.

Issue (i): Whether the detention order could be sustained on the basis of a solitary incident.

Analysis: A single incident can justify preventive detention if the surrounding circumstances disclose an organised act, preparation, expertise, and a reasonable inference of propensity and potentiality to repeat prejudicial conduct. The incident was not treated as a bare isolated act; it involved advance ticketing, coordinated travel, timed meeting at transit, and delivery of contraband in a planned manner.

Conclusion: The detention order was sustainable on the ground that the material disclosed organised conduct and future potentiality.

Issue (ii): Whether the detaining authority's subjective satisfaction was vitiated by the detenue's surrender of passport and by the alleged non-placement of a vital document.

Analysis: The fact that the passport was with the authorities did not foreclose the possibility of abetment, since the detenue's role included planning and logistical coordination rather than mere physical carriage. As to the cancellation-of-bail application, the record showed that the authority was informed of the pendency of that matter and the document was not treated as one whose non-placement impaired the subjective satisfaction.

Conclusion: The subjective satisfaction was not vitiated on these grounds.

Issue (iii): Whether preventive detention was unwarranted because the ordinary law was sufficient.

Analysis: Preventive detention is not barred merely because criminal proceedings are available. In the facts found, the conduct disclosed an organised smuggling operation and not a case adequately met by ordinary criminal process alone. The authority was entitled to act preventively to stop future abetment.

Conclusion: Resort to preventive detention was justified.

Issue (iv): Whether unexplained delay in execution of the detention order snapped the live link and invalidated the order.

Analysis: The authorities knew the detenue's address and residence details, yet the steps taken for execution were not prompt enough and the explanation for the delay was unsatisfactory. Preventive detention requires prompt execution, and unexplained delay weakens the live link between the grounds and the detention.

Conclusion: The detention order was vitiated by unexplained delay in execution.

Final Conclusion: Although the detention order was otherwise found defensible on the merits, the unexplained delay in its execution rendered it unsustainable and the writ petition was allowed.

Ratio Decidendi: In preventive detention matters, an unexplained delay in executing the detention order can snap the live link between the alleged prejudicial activity and the need for detention, thereby vitiating the order even where the substantive grounds may otherwise be sufficient.
