David Josiah Brewer,
South Carolina v. United States…
“ If, under given circumstances, a charge is made for transportation, and hence a revenue is earned, may the states cripple that service by taxation? It is no answer to the demonstration which results from these illustrations to say that the cases concern purely governmental functions of the United States, and, therefore, the states cannot tax the exercise of such functions. May I ask are these functions on the part of the United States any more govermental than is the power of the government of South Carolina to absolutely control at will the liquor traffic in that state? ”
