Indeed, at the time of assessment, the appellant/assessee had failed to produce any explanation or evidence in support of the entries regarding purchases made from unregistered dealers. In the penalty proceedings, however, the appellant/assessee produced affidavits of 13 unregistered dealers out of whom 12 were examined by the Officer. The Officer recorded their statements and did not find any infirmity therein including about their credentials. The dealers stood by the assertion made by the appellant/assessee about the purchases on credit from them; and which explanation has been accepted by the appellate authority in paragraphs 17 and 19 of the order dated 13.1.2011. 15. To put it differently, the factual basis on which the Officer formed his opinion in the assessment order dated 30.11.2000 (for assessment year 19981999), in regard to addition of Rs.2,26,000/( Rupees two lakhs twenty six thousand only), stands dispelled by the affidavits and statements of the concerned unregistered dealers in penalty proceedings. That evidence fully supports the claim of the appellant/assessee.
