defect is noticeable on receipt of the certificate, it is for the deductee who makes a claim on the basis of the certificate to get the defects cured. This is an instance where substantial time had elapsed for curing the defects, which according to the Department, is attributable to the assessee. When such a view is possible and the claim for interest is denied on that specific period, I do not think that this Court will be justified in taking a different view. No doubt, as rightly contended by the learned counsel for the petitioner, once the defect is cured, the parties have to go back to their original position, but the question is whether there is an obligation on the part of the Department to pay interest on the amount to be refunded. When a statute in the form of Section 244A(2) clearly specifies that interest need not be paid if the proceedings of refund is delayed for reasons attributable to the assessee, in that event, the respondents having refused interest on the basis of factual finding relying upon the statutory provision, I do not think that this Court will be justified in interfering with the said orders.
