Preventive detention grounds need basic facts, not every detail, and conduct affecting community life may justify public order detention.

In preventive detention, the first paragraph of the grounds was treated as a mere introductory preamble, not an independent ground, so it could not be challenged separately for vagueness. The Court held that the remaining grounds supplied sufficient basic facts to permit an effective representation under Article 22(5); minute evidentiary details were not required and the detention was not vitiated on vagueness. It further held that the alleged conduct, viewed in the context of the wider agitation, had enough reach and impact to affect the even tempo of community life and therefore fell within public order rather than a mere law and order problem. The detention order was upheld.

Issues: (i) whether the first paragraph of the grounds of detention was merely introductory or constituted a substantive ground of detention; (ii) whether the remaining grounds were so vague as to deny an effective representation under Article 22(5) of the Constitution; and (iii) whether the alleged activities related to maintenance of public order rather than merely law and order.

Issue (i): whether the first paragraph of the grounds of detention was merely introductory or constituted a substantive ground of detention.

Analysis: The opening part of the first paragraph described the detenu's identity and position, while the remaining part broadly indicated the agitation in which he was said to be involved. Reading the grounds as a whole, the document showed that the first paragraph only set out the background and mode of participation of the organisations concerned, whereas the specific acts relied on were contained in the later paragraphs. The Court treated the paragraph as a preamble or introduction and not as an operative ground.

Conclusion: The first paragraph was only introductory and could not be attacked for vagueness as an independent ground of detention.

Issue (ii): whether the remaining grounds were so vague as to deny an effective representation under Article 22(5) of the Constitution.

Analysis: The governing principle applied was that the detenu must receive the basic facts constituting the grounds, but not every minute evidentiary detail. Vagueness is relative and depends on the facts of each case. The Court found that paragraphs 2 and 3 gave sufficient basic facts, including the nature of the agitation, the dates, and the detenu's role, to enable a meaningful representation. The omission of further particulars did not, on the facts, vitiate the detention.

Conclusion: The remaining grounds were not vague in a legally fatal sense and the detenu's right to make an effective representation was not infringed.

Issue (iii): whether the alleged activities related to maintenance of public order rather than merely law and order.

Analysis: The distinction between public order and law and order depends on the degree and extent of the disturbance and its impact on society. In the context of the widespread agitation in Assam and the specific incidents alleged, the Court held that the activities had sufficient reach and potential to disturb the even tempo of community life. The allegations therefore fell within the sphere of public order.

Conclusion: The detention was supportable on the ground of maintenance of public order.

Final Conclusion: The detention order was upheld and the appeal failed on all substantive challenges.

Ratio Decidendi: In preventive detention, a ground is not vague if it supplies the basic facts needed for an effective representation, and conduct having a sufficient impact on the community's even tempo may justify detention on the ground of public order.
