Dear Assumi Sir,
In the case of Maneka Gandhi vs. Union of India AIR 1978 Supreme Court 597, their Lordships of the Supreme Court laid down the following principle. The Courts insists upon disclosure of reasons in support of the order on three grounds :
(1) the party aggrieved has the opportunity to demonstrate before the appellate or revisional court that the reasons which persuaded the authority to reject his case were erroneous ;
(2) the obligation to record reasons operates as a deterrent against possible arbitrary action by executive authority invested with judicial power;
and (3) it gives satisfaction to the party against whom the order is made. The power to refuse to disclose reasons in support of the order is “exceptional in nature and it ought to be exercised fairly, sparingly and only when fully justified by the exigencies of an uncommon situation”.
Similar view has been expressed in S.N. Mukherjee vs. Union of India AIR 1990 Supreme Court 1984.
