Pierce Butler, Bonwit Teller Company v. United States…
“ The question here is to be distinguished from that which would have arisen if, contrary to the taxpayer's insistence, the Commissioner had held that what was done did not constitute a filing of a claim. No statute provides for review of the Commissioner's determinations in favor of taxpayers when made within the scope of his authority. Such rulings are entitled to much weight. In this case he had already found that in 1919 plaintiff had overpaid its tax in the amount stated. He needed no additional information to enable him to determine whether credit or refund should then be made. ”
