Byron White, United States v. Boyd (378 U.S. 39…
“ There a South Carolina statute imposed a sales tax and a tax on use, defined as the exercise of any right or power over property 'by any transaction in which possession is given,' on contractors 'purchasing property * * * as agents of the United States or its instrumentalities.' The Government sought to enjoin collection of the tax from the du Pont Company, which performed management services under a contract, similar in many respects to Carbide's, with the AEC. The difference, however, was that du Pont was paid costs plus a nominal fee of one dollar for its entire undertaking. ”
