Pierce Butler, United States v. Mitchell (271 U.S. 9…
“ The government did not contend that, if deductible at all, the estate taxes could not be deducted in that case because the return was made on the basis of income actually received in 1918, whereas the estate tax, accruing in that year, was not paid until 1919. That question was not presented to the court for decision, and no such question was considered or decided. It is not to be thought that a question not raised by counsel or discussed in the opinion of the court has been decided merely because it existed in the record and might have been raised and considered. ”
