James Clark McReynolds,
Southern Pacific Company v. Jensen…
“ I freely concede the authority of Congress to modify the rules of maritime law so far as they are administered in the Federal courts, and to make them binding upon the courts of the states so far as they affect interstate or international relations, or regulate 'commerce with foreign nations, and among the several states, and with the Indian tribes.' What I contend is that the Constitution does not, proprio vigore, impose the maritime law upon the states except to the extent that the admiralty jurisdiction was exclusive of the courts of common law before the Constitution ”
