Felix Frankfurter,
Commissioner of Internal Revenue v…
“ It is taking too much liberty even with tax provisions to read out a defining clause that Congress has written in merely because Congress permitted desirable revenue to escape the tax collector's net. The only judicial problem is whether the proceeds constitute a type of income which Congress has designated as taxable. That type must have the characteristic of being "fixed or determinable annual or periodical gains, profits, and income." A lump-sum payment for an exclusive property right, transferable and transferred by the taxpayer, simply does not meet that qualification. ”
