S. 147 : Reassessment-Mere non quoting of reasons formed by AO in notice would not vitiate entire proceedings- communication of all reasons for reopening of assessment at time of issuance of notice was not necessary—When notice was issued within timeline provided by virtue of s. 149(1)(b), challenge raised by assessee on point of limitation was not sustainable—Since assessee was holding high position of Union Minister and since, transaction were believed to be multi folded, which warranted further investigation, issuance of notices on multiple choice could not be faulted—Writ petition was dismissed. [S.148/ 149(1)(b)]
