Preventive detention fails when vague or irrelevant grounds block effective representation and undermine subjective satisfaction.

A preventive detention order is invalid where any material ground supplied to the detenu is so vague that it lacks essential particulars and prevents an effective representation under Article 22(5). The grounds must be read as a whole, and allegations without place, manner, or precise conduct were treated as defective; the order was vitiated on that basis. The order is also invalid where irrelevant allegations are taken into account by the detaining authority, because matters not showing conduct prejudicial to public order cannot support subjective satisfaction under the preventive detention statute. The detention was therefore held unsustainable in law.

Issues: (i) Whether the detention order was vitiated because some of the grounds supplied to the detenu were vague and prevented an effective representation under Article 22(5) of the Constitution. (ii) Whether some of the grounds were irrelevant to the statutory requirement of preventive detention under section 8 of the Jammu and Kashmir Public Safety Act, 1978, and thereby invalidated the detention.

Issue (i): Whether the detention order was vitiated because some of the grounds supplied to the detenu were vague and prevented an effective representation under Article 22(5) of the Constitution.

Analysis: The grounds furnished to the detenu were held to be part of the detention grounds as a whole and could not be dissected into a mere preamble, background, and operative grounds. Certain allegations were found to be vague because they lacked essential particulars such as place, manner, and the precise nature of the alleged conduct. A vague ground deprives the detenu of the earliest opportunity to make an effective representation, which is the substance of Article 22(5).

Conclusion: Yes. The detention was vitiated by vagueness of material grounds, and this was sufficient to invalidate the order.

Issue (ii): Whether some of the grounds were irrelevant to the statutory requirement of preventive detention under section 8 of the Jammu and Kashmir Public Safety Act, 1978, and thereby invalidated the detention.

Analysis: Several allegations were found not to fall within the statutory concept of acting in any manner prejudicial to the maintenance of public order. Expressions such as protest, revolt, or revolution, without a showing of incitement to violence or other conduct covered by the statute, were treated as insufficient. The inclusion of an irrelevant ground among the material considered by the detaining authority was held to vitiate the subjective satisfaction supporting detention.

Conclusion: Yes. The order of detention was invalid because irrelevant grounds had been taken into account.

Final Conclusion: The detention order could not stand in law, as the grounds furnished were both vague and in part irrelevant, thereby infringing the constitutional safeguard under Article 22(5) and defeating the statutory basis for preventive detention.

Ratio Decidendi: A preventive detention order is invalid if any material ground supplied to the detenu is so vague that it prevents an effective representation, or is irrelevant to the statutory test for detention, because such defects vitiate the detenu's constitutional right under Article 22(5) and the detaining authority's subjective satisfaction.
