Constitutional and Statutory rights guaranteed under Article 22(5) of the Constitution of India and Section 13 of the Jammu & Kashmir Public Safety Act, 1978, unless and until the material on which detention order is based, is supplied to him. It is only after detenu has all the said material available that he can make an effort to convince detaining authority and thereafter the Government that their apprehensions vis-à-vis his activities are baseless and misplaced. If detenu is not supplied the material, on which detention order is based, he will not be in a position to make an effective representation against his detention order. Failure on the part of detaining authority to supply material, relied at the time of making detention order to detenu, renders detention order illegal and unsustainable. These views are fortified, given the law laid down by the Apex Court in Thahira Haris Etc. Etc. v. Government of Karnataka, AIR 2009 SC 2184; Union of India v. Ranu Bhandari, 2008, Cr. L. J. 4567; Dhannajoy Dass v. District Magistrate, AIR, 1982 SC 1315; Sofia Gulam Mohd Bham v. State of Maharashtra and others AIR 1999 SC 3051; and Syed Aasiya Indrabi v. State of J&K &ors, 2009 (I) S.L.J 219 . My views are also cemented by the judgement dated 18.05.2021 delivered in WP(Crl) No. 107/2020 titled Mohammad Rafiq Mir v. UT of J&K and another.
