Stanley Forman Reed,
Mayo v. United States — Opinion of the Court
“ The District Court, one judge dissenting, enjoined the application of Florida law to the above described acts of the United States on the ground of federal immunity from state regulation.Since the United States is a government of delegated powers, none of which may be exercised throughout the Nation by any one state, it is necessary for uniformity that the laws of the United States be dominant over those of any state. Such dominancy is required also to avoid a breakdown of administration through possible conflicts arising from inconsistent requirements. ”
