Hugo Black,
United States v. Township of Muskegon…
“ If under certain conditions the State can tax Continental for use of government property in connection with its business conducted for profit-and as set forth in No. 26 we are of the opinion that it can-the fact that Continental was carrying out a contract with the Government does not materially alter the case. Continental was still acting as a private enterprise selling goods to the United States. In a certain loose way it might be called an 'instrumentality' of the United States, but no more so than any other private party supplying goods for his own gain to the Government. ”
