(1) THIS is an appeal by a detenu detained under the National Security Act. His application for the issue of a writ of habeas corpus was rejected by the High court of Madhya Pradesh, and hence this appeal.

(2) THE order of detention recites that the District Magistrate is satisfied that Aidal Singh should be detained "with an intention to protect him from commission of any act in contravention with maintenance of public security".
