be based on evidence or new materials not considered earlier. However, if all such materials, informations, documents are identified for initiation of proceedings by reopening the assessment, it is for the Assessee to submit his returns explaining the stand taken and to defend his case by availing the opportunities to be provided. Contrarily, at the initiation stage itself, the assessee cannot expect that the entire discussions are to be made. If the entire adjudication made by the assessee prior to issuance of notice, the same would violate the principles of natural justice. Therefore, the Section contemplates that if there is any reason to believe, then the reopening is permissible and after reopening, the opportunities are to be provided to the assessee and by availing the opportunity, the assessee is at liberty to defend his case by producing documents, evidence and statements etc., This being the scope of the provisions, the contentions raised regarding the merits, more specifically, Business Development Commission etc., are to be adjudicated by the Assessing Officer and those documents, information, and materials are not made available before this Court for an adjudication and such an exercise need not be done by the High Court.
