Robert H. Jackson, Bethlehem Steel Company v. New York State Labor Relations Board…
“ While what the State does she does on sufferance, in ascertaining whether Congress has allowed State action we are not to consider the matter as though Congress were conferring a mere bounty, the extent of which must be viewed with a thrify eye. When construing federal legislation that deals with matters that also lie within the authority, because within the proper interests, of the States, we must be mindful that we are part of the delicate process of adjusting the interacting areas of National and State authority over commerce. ”
