William R. Day,
Southern Railway Company v. Josephine King No 140 Southern Railway Company…
“ Statutes which require the speed of such trains to be checked at all crossings so situated might not only be a regulation, but also a direct burden upon interstate commerce, and therefor beyond the power of the state to enact.It is the settled law of this court that one who would strike down a state statute as violative of the Federal Constitution must bring himself, by proper averments and showing, within the class as to whom the act thus attacked is unconstitutional. ”
