Noah Haynes Swayne,
Foster v. Master and Wardens of the Port of New Orleans…
“ We hold the statute to be void.In expressing these views, we have no purpose to impugn any thing heretofore said by this court as to the power of the States to establish inspection, quarantine, health, and other regulations, within the sphere of their acknowledged authority. The constitutional validity of such regulations is as clear as the power of Congress to establish regulations of commerce. ”
