We note that the reasons in support of the impugned notice accept the fact that as a matter of regular business practice, a broker in the stock exchange makes modifications in the client code on sale and / or purchase of any securities, after the trading is over so as to rectify any error which may have occurred while punching the orders. The reasons do not indicate the basis for the Assessing Officer to come to reasonable belief that there has been any escapement of income on the ground that the modifications done in the client code was not on account of a genuine error, originally occurred while punching the trade. The material available is that there is a client code modification done by the Assessee’s broker but there is no link from there to conclude that it was done to escape assessment of a part of its income. Prima facie, this appears to be a case of reason to suspect and not reason to believe that income chargeable to tax has escaped assessment
