Preventive detention and public order: relevant material, even if inadmissible at trial, can sustain detention when violence terrorises the public.

Preventive detention is sustained where the detaining authority has relevant material for subjective satisfaction that the person's conduct prejudicially affects public order. Strict rules of evidence do not apply, so statements and other material not admissible in a criminal trial may still be relied on. On the facts, the court found adequate material showing violent incidents, intimidation and terror in a public locality, and held that these affected public order rather than a mere law and order issue. The claimed procedural objections, including advance notice of next-friend assistance, unexplained delay, and lack of sufficient material, were rejected, and the detention was upheld.

Issues: (i) whether failure to inform the detenu in advance of the claimed right to next-friend assistance and rebuttal evidence before the Advisory Board vitiated the detention; (ii) whether material not strictly admissible under the Evidence Act or the Code of Criminal Procedure could form part of the basis for preventive detention; (iii) whether there was inadequate material to support the inference of disturbance of the even tempo of society; (iv) whether the detention order was vitiated by unexplained delay; and (v) whether the incidents disclosed only law and order problems and not a threat to public order.

Issue (i): Whether failure to inform the detenu in advance of the claimed right to next-friend assistance and rebuttal evidence before the Advisory Board vitiated the detention.

Analysis: The detenu had been informed twice of his right to make a representation and to seek personal hearing. The claimed right to next-friend assistance and rebuttal evidence was not shown to be mandatory as a matter of constitutional or statutory requirement, and no request for adjournment was made at the hearing. The absence of an advance intimation of such claimed facilities did not, on the facts, invalidate the proceedings.

Conclusion: The objection was rejected and the detention was not vitiated on this ground.

Issue (ii): Whether material not strictly admissible under the Evidence Act or the Code of Criminal Procedure could form part of the basis for preventive detention.

Analysis: Preventive detention rests on the detaining authority's subjective satisfaction and is not a criminal trial. Strict rules of evidence do not govern such proceedings, and the authority may rely on material sufficient to reach preventive satisfaction, including statements and other material not admissible in a regular trial.

Conclusion: The contention failed; such material could be used for arriving at subjective satisfaction.

Issue (iii): Whether there was inadequate material to support the inference of disturbance of the even tempo of society.

Analysis: The incidents disclosed violent conduct creating terror among residents and bystanders. In preventive detention, the adequacy of material is not open to reassessment as if on evidence in a criminal case; the court only examines whether relevant material existed for the inference drawn.

Conclusion: Adequate material existed and the challenge was rejected.

Issue (iv): Whether the detention order was vitiated by unexplained delay.

Analysis: The sequence of events showed that the proposal was moved after the last arrest and release on bail, received through the normal channel, and the order was passed promptly. The service delay was explained by inability to trace the detenu. No snapping of the live link between the activities and the need for detention was shown.

Conclusion: The delay was explained and did not invalidate the detention.

Issue (v): Whether the incidents disclosed only law and order problems and not a threat to public order.

Analysis: The incidents were not isolated private disputes; they involved repeated violent assaults, intimidation of bystanders, and terror in a public locality. Conduct that terrorises the public and disturbs the even tempo of society affects public order.

Conclusion: The incidents concerned public order, not merely law and order.

Final Conclusion: The detention order was sustained on all material challenges and the habeas corpus petition failed.

Ratio Decidendi: In preventive detention, the court tests only whether relevant material existed for the detaining authority's subjective satisfaction that the person's conduct prejudicially affected public order, and it will not invalidate the detention merely because the material would be inadmissible in a criminal trial or because the sufficiency of the material is disputed.
