allow further time for C forms to be filed on sufficient cause, the rest of it is mere procedure or follow up action. Where the assessing authority is satisfied, in a given case, about the existence of sufficient cause, it must necessarily be followed up by appropriate action, such as reopening the assessment already completed. Perhaps the requisite corrective action can be taken by invoking the assessing authority's statutory power of rectification of mistakes. Even otherwise, the implementation, in appropriate cases, of the power to allow further time cannot be withheld on the excuse that there is not express provision either in the statute or in the statutory rules for reopening the assessment. When the power is there and the facts are there demanding its exercise, the implementation must be done as a matter of course, on the doctrine of implied or ancillary powers. Where there is a power, and where there is a will, there will be a way. It is, however, unnecessary to pursue the line of discussion further, because the particular problem we are concerned with in the two cases before us is quite different. What we are asked to consider, and what we have been engaged in discussing so far, is whether an appellate authority has the same power as the assessing authority to allow further time for accepting C forms, and not how and by what process the assessing authority itself could exercise the power after the completion of the assessment.
