must be communicated to ·,lhe detenue .nor has it been shown how the communication . of thiS decision would have beelll beneficial to the detenue. He referred.to the case of Achhar Singh v. State of ·P11njab(1 ), where this Court had said that 'the omission to convey the order under Section 11 .of the Indian Preventive Detention Act does not make the detention illegal or result in infringement B of the petitioner's fundamental rights'. After referring to this decision this Cow:t however, pointed out, if that be the position under Section 11 of the Indian Preventive Detention Act which provides for the making of a formal order all the more mwt the position be the same .under Section 14 of the Jammu & Kashmir Preventive Detention Act which .does not in terms require any c formal order to be made. Whatever may be the position under the Jammu ,& Kashmir Act under the Act which we are considering as pointed out earlier the State Government has to confirm the opinion of the Board that there is cause for the detention of the person concerned which confirmation cannot •purely be a mental act, a subjective one but must result in an objective action namely that it should be recorded in writing. Though there is D no provision in the Act an order of c®firmation which has the effect of extending the period of detention beyond the mandatory period of three months must be made known to the detenue. in our view there is no warrant or justification for an order confirming the detention on the opinion .of the Board which has the effect of extending the period of detention remaining in the files of the E executive without the same being communicated to the person most concerned-the detenue--whose freedom has been subjected to jeopardy. He is entitled to know that the Board had considered his ·representation as well as his personal submissions if he has ch<>E::n to appear before it and that it had been found that there was sufficient cause for his detention and that the State F Governm,ent had ag!'tled with it. In Biren Dutta & Ors. v. Chief Commissio,.er of Tripura & Another(2 ), another Constitution Bench of this C-0urt \lad 10 consider this matter on the provisions of Rule 30(.1 Hb) and Rule 30A($) of the Defence of India Rules 1962. -Oajendragadkar, J. speaking for the Court held that even Ullder .th()Se rules the authority e1'ercisinp: the ·pow.er under rule 30A( % ) hou.ld ·eoo.rd i doision clearly and UIJl»llG biguously eru\ing .the period of 4eteniien beyond six menths which wa.< the limit under those rules, to; he observed, "Af(er all, the. liberty .of. the citizen is in question and ·if ·the ention of the detue ris intend6d to be contjnued as a result of the dee.is.ion reacht;d tzy. jhe approprite authority, it ··Should say so in clear .anid ~bfgµlilus ~mns" .. w;ID!e the decision of the -OovH ernment to ,GQQ,fir.m .the fJpinio!l of the Boan! which according to
