Case Note & Summary
The case involved Hans Muller, a West German subject, who was placed under preventive detention by the West Bengal Government under section 3(1)(b) of the Preventive Detention Act, 1950, on the grounds of being a foreigner and the necessity for his expulsion from India. The petitioner challenged the validity of his detention, arguing that the section under which he was detained was ultra vires the Constitution, contravening Articles 14, 21, and 22, and that the detention was made in bad faith. The High Court dismissed his petition, leading to an appeal in the Supreme Court. The Supreme Court examined the legislative competence of Parliament to enact the Preventive Detention Act and concluded that it was valid under the Constitution, as it fell within the scope of Entries 9 and 10 of the Union List. The court also addressed the issue of good faith, finding no evidence that the West Bengal Government intended to detain the petitioner for purposes other than those stated in the detention order. Ultimately, the Supreme Court upheld the validity of the detention order and dismissed the appeal with costs.
