Preventive detention fails where execution is unexplained, while minor service defects without prejudice do not vitiate detention.

Minor defects in the communication of preventive detention grounds do not vitiate detention unless prejudice is shown; an unsigned copy of the last page and unparticularised claims of illegible documents were insufficient to defeat the detenu's right to make an effective representation under Article 22(5). Delay in passing the detention order was explained by continuing investigation and did not break the live nexus, but the unexplained delay in executing the order, without adequate particulars of service efforts, undermined the genuineness of the detention decision. The detention was therefore invalidated on the ground of unexplained delay in execution.

Issues: (i) whether the detention was vitiated because the grounds of detention served on the detenu were unsigned and certain supplied documents were illegible so as to defeat the right to make an effective representation; (ii) whether there was unexplained delay in passing the detention order and in executing it, sufficient to invalidate the detention.

Issue (i): Whether the detention was vitiated because the grounds of detention served on the detenu were unsigned and certain supplied documents were illegible so as to defeat the right to make an effective representation.

Analysis: The communication of grounds must be meaningful so that the detenu can make an effective representation under Article 22(5) of the Constitution of India. However, the defect in the last page not bearing the detaining authority's signature did not show any mismatch between the copy served and the original, nor was any prejudice demonstrated. Likewise, the allegation of illegible documents remained unparticularised and no material was shown to have prevented an effective representation.

Conclusion: The unsigned copy and alleged illegibility did not vitiate the detention, as no prejudice to the petitioner was established.

Issue (ii): Whether there was unexplained delay in passing the detention order and in executing it, sufficient to invalidate the detention.

Analysis: Delay in passing a preventive detention order is material only if it breaks the live nexus between the incident and the detention. On the facts, the delay in making the order was explained by continuing investigation and related proceedings, so the nexus was not held to be severed. In contrast, the execution of the order after its issuance was not supported by a satisfactory explanation for the relevant period, and no adequate particulars of efforts to serve the order were furnished. Such unexplained delay in execution cast doubt on the genuineness of the detention decision.

Conclusion: The delay in passing the order did not invalidate it, but the unexplained delay in execution did, and the detention was quashed on that ground.

Final Conclusion: The detention orders could not survive judicial scrutiny because the delay in execution remained unexplained, rendering the preventive detention invalid.

Ratio Decidendi: In preventive detention matters, minor defects in service do not vitiate the detention absent prejudice, but unexplained delay in executing the detention order may invalidate it where no satisfactory explanation is furnished.
