William Johnson, Gibbons v. Ogden (22 U.S. 1) — Concurring Opinion (1824)
“ Were every law on the subject of commerce repealed tomorrow, all commerce would be lawful, and, in practice, merchants never inquire what is permitted, but what is forbidden commerce. Of all the endless variety of branches of foreign commerce now carried on to every quarter of the world, I know of no one that is permitted by act of Congress any otherwise than by not being forbidden. No statute of the United States that I know of was ever passed to permit a commerce unless in consequence of its having been prohibited by some previous statute. ”
