Charles Evans Hughes, Helvering v. Mountain Producers Corporation…
“ Regard must be had to substance and direct effects. And, where it merely appears that one operating under a government contract or lease is subjected to a tax with respect to his profits on the same basis as others who are engaged in similar businesses, there is no sufficient ground for holding that the effect upon the government is other than indirect and remote. We are convinced that the rulings in Gillespie v. Oklahoma, supra, and Burnet v. Coronado Oil & Gas Company, supra, are out of harmony with correct principle and accordingly they should be, and they now, are, overruled. ”
