Felix Frankfurter,
McLeod v. J. E. Dilworth Company…
“ A use tax is a tax on the enjoyment of that which was purchased. In view of the differences in the basis of these two taxes and the differences in the relation of the taxing state to them, a tax on an interstate sale like the one before us and unlike the tax on the enjoyment of the goods sold, involves an assumption of power by a State which the Commerce Clause was meant to end. ”
