Preventive detention and mala fides: heavy burden to prove abuse of power, with detention upheld on the facts.

Preventive detention depends on the detaining authority's satisfaction on the materials before it, and a court will not substitute its own view for that of the authority. The order may still be invalidated if mala fides or abuse of power is proved, but the burden on the detenu is heavy. On the stated facts, surrounding circumstances raised suspicion, yet the materials did not establish an improper or indirect motive by the District Magistrate. Prevailing communal tension, the detainee's press conference, and the apprehended effect of his presence in Delhi were treated as sufficient to negate any finding of simulated or colourable satisfaction, so the detention was upheld.

Issues: Whether the detention order was liable to be struck down on the ground that it was made mala fide and in abuse of the power conferred by the Preventive Detention Act, 1950.

Analysis: The power of preventive detention depends upon the authority's satisfaction on the materials placed before it, and the Court will not substitute its own view for that of the detaining authority. A detention order can nevertheless be invalidated if mala fides or abuse of power is established, but the burden lies heavily on the detenu. On the facts, the surrounding circumstances created suspicion, but the materials did not establish that the District Magistrate acted on an improper or indirect motive. The prevailing communal tension, the petitioner's press conference, and the apprehended effect of his presence in Delhi were held to be sufficient to negative a finding of simulated or colourable satisfaction.

Conclusion: The detention order was not proved to be mala fide or an abuse of power and was upheld.
