Held, that Revenue have tried to traverse beyond the disclosed reasons in their affidavit which is not permissible. The same cannot be taken into consideration, while examining validity of notice under section 148. The reasons which are recorded by the Assessing Officer for re-opening an assessment are the only reasons which can be considered when the formation of the belief is impugned; such reasons cannot be supplemented subsequently by affidavit, thus, attempt made by Revenue to reopen the concluded assessment is not at all justified and consequently the impugned notice cannot be sustained. - GATEWAY LEASING (P.)
