Preventive detention upheld where mala fides, vagueness, and non-disclosure challenges failed under article 22.

Detention was upheld because the detaining authority was found to have acted bona fide and with due application of mind, so the mala fides challenge failed. The grounds of detention were sufficiently definite to be intelligible and to permit a representation, even if not drafted with ideal precision, so they were not vague. Non-disclosure of further particulars was justified where the detaining authority considered disclosure contrary to public interest under article 22(6); no separate communication of that decision was required in the absence of a request for particulars. The detention order was sustained and the appeal was dismissed.

Issues: (i) Whether the detention order was vitiated by mala fides or non-application of mind; (ii) Whether the grounds of detention were vague; (iii) Whether non-disclosure of particulars could be justified on the ground of public interest.

Issue (i): Whether the detention order was vitiated by mala fides or non-application of mind.

Analysis: The allegations of mala fides were tested against the surrounding circumstances and the material placed before the Court. The Court held that the relevant question was whether the detaining authority itself acted bona fide and applied its mind, not whether the police were alleged to have acted improperly. On the material before it, there was no basis to conclude that the Government acted otherwise than bona fide or without application of mind.

Conclusion: The challenge based on mala fides and non-application of mind failed.

Issue (ii): Whether the grounds of detention were vague.

Analysis: The governing test is whether the grounds communicated are capable of being intelligently understood and are sufficiently definite to enable a representation against the detention. The grounds here stated the nature of the alleged espionage activity, the role of financial assistance from Portuguese authorities, the collection and communication of intelligence, and the object of prejudicing relations between India and Portugal. Though not as precise as could be desired, they were held to be adequate in the context of the alleged activities, and the absence of any request for further particulars was treated as a relevant circumstance.

Conclusion: The grounds were not held to be vague.

Issue (iii): Whether non-disclosure of particulars could be justified on the ground of public interest.

Analysis: The Court explained that the right to be furnished grounds and adequate particulars under article 22(5) is subject to article 22(6), which permits withholding facts whose disclosure is considered against public interest by the detaining authority. It was held that the obligation to decide on disclosure rests with the detaining authority, and that no separate communication of the decision not to disclose was required in the absence of any request for particulars. The contention that the non-disclosure was mala fide was also rejected.

Conclusion: The claim of privilege and non-disclosure was upheld.

Final Conclusion: The detention order was sustained, and the appeal was dismissed after rejection of all challenges to the validity of the detention.

Ratio Decidendi: In preventive detention matters, detention is not invalid unless mala fides or non-application of mind by the detaining authority is established, and the grounds communicated are so indefinite as to deny a reasonable opportunity of representation; disclosure of particulars may be withheld where the detaining authority considers disclosure contrary to public interest under article 22(6).
