George Sutherland, Steward Machine Company v. Davis…
“ The people of the United States, by their Constitution, have affirmed a division of internal governmental powers between the federal government and the governments of the several states committing to the first its powers by express grant and necessary implication; to the latter, or to the people, by reservation, 'the powers not delegated to the United States by the Constitution, nor prohibited by it to the States.' The Constitution thus affirms the complete supremacy and independence of the state within the field of its powers. ”
