Assessee-company claimed deduction towards provision for doubtful debts for purpose of computation of MAT under section 115JB. Assessing Officer accepted  the computation without discussion. Commissioner passed the revision order and directed the Assessing Officer to re-examine issue.   Tribunal affirmed the order of the revision. On appeal the Court held that  since Assessing Officer did not show any application of mind and mechanically accepted statement of assessee, Principal Commissioner was justified in exercising his jurisdiction under section 263 of the Act.
