was satisfied that with a view to prevent detenu from acting in any manner prejudicial to the security of the State, it was necessary to detain him under necessary provisions of law. So, it is on the basis of dossier and other connected material/documents that impugned detention order has been passed by detaining authority. Perusal of grounds of detention gives reference to various alleged activities of detenu that appears to have weighed with detaining authority, while making detention order. The detention record, as noted above, does not indicate that copies of related relevant material including dossier were ever supplied to detenu, on the basis whereof impugned detention order has been passed. The aforesaid material, thus, assumes importance in the facts and circumstances of the case. It needs no emphasis, that detenu cannot be expected to make a meaningful exercise of his Constitutional and Statutory rights guaranteed under Article 22(5) of the Constitution of India and Section 13 of the J&K 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 the detention order is based, he will not be in a position to make an effective representation against his detention order. The failure on the part of the detaining authority to supply the material, relied at the time of making the detention order to the detenu, renders the detention order illegal and unsustainable. In this regard ,I may draw support from the law laid down in the cases of 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 . 11. The Supreme Court in Abdul Latief Abdul Wahab Sheikh v. B.K. Jha, 1987 (2) SCC 22 has held that it is only the procedural requirements, which are the only safeguards available to the detenu, that is to be followed and complied with as the Court is not expected to go behind the subjective satisfaction of the detaining authority. In the present case, the procedural requirements, as discussed above, have not been followed and complied with by the respondents in letter and spirit and resultantly, the impugned detention needs to be quashed.
