Preventive detention distinct from criminal proceedings; disputed alibi will not displace subjective satisfaction based on relevant material.

Preventive detention under the Maintenance of Internal Security Act is not barred merely because the same facts may also support proceedings under Chapter VIII of the Code of Criminal Procedure. The two regimes operate in different fields: criminal proceedings require proof of objective facts, while preventive detention rests on the authority's subjective satisfaction about past conduct and the likelihood of future prejudicial activity. In habeas corpus review, the court does not re-examine disputed factual denials or an alibi where the detaining authority has considered relevant material and the factual foundation is not shown to be absent. The detention was therefore upheld.

Issues: (i) Whether preventive detention under the Maintenance of Internal Security Act could be invalidated merely because the facts alleged in the grounds might also attract proceedings under Chapter VIII of the Code of Criminal Procedure. (ii) Whether the detention order was unsustainable because the detenu denied the truth of the grounds and pleaded alibi.

Issue (i): Whether preventive detention under the Maintenance of Internal Security Act could be invalidated merely because the facts alleged in the grounds might also attract proceedings under Chapter VIII of the Code of Criminal Procedure.

Analysis: The availability of criminal prosecution or preventive proceedings under Chapter VIII of the Code of Criminal Procedure does not bar recourse to preventive detention. The two jurisdictions are distinct and operate in different fields. Proceedings under the criminal law depend on proof of objective facts, whereas detention under the Act rests on the authority's subjective satisfaction based on past conduct and the likelihood of future prejudicial activity affecting public order or the security of the State. The Act is intended to meet a more serious preventive need and is not excluded merely because the same facts may also justify criminal action.

Conclusion: The contention that detention was barred because the acts could also have been dealt with under the Code of Criminal Procedure was rejected.

Issue (ii): Whether the detention order was unsustainable because the detenu denied the truth of the grounds and pleaded alibi.

Analysis: In habeas corpus proceedings, the Court does not undertake an independent inquiry into disputed questions of fact when the detaining authority has affirmed the grounds and the material has been considered by the Government and the Advisory Board. The District Magistrate's assessment and subjective satisfaction were treated as entitled to due weight, and the challenged grounds were accepted as relevant to the object of detention. On that basis, the Court found no legal infirmity, mala fides, or non-existence of the factual foundation for detention.

Conclusion: The challenge based on denial of the allegations and plea of alibi failed.

Final Conclusion: The detention order was upheld and the writ petition failed, as the statutory and factual challenges did not establish any illegality in the preventive detention.

Ratio Decidendi: Preventive detention under the Act is not excluded by the mere possibility of criminal prosecution on the same facts, and disputed factual denials do not warrant interference in habeas corpus where the detaining authority's subjective satisfaction is founded on relevant material.
