Joseph McKenna, Hipolite Egg Company v. United States…
“ The statute rests, of course, upon the power of Congress to regulate interstate commerce; and, defining that power, we have said that no trade can be carried on between the states to which it does not extend, and have further said that it is complete in itself, subject to no limitations except those found in the Constitution. We are dealing, it must be remembered, with illicit articles,-articles which the law seeks to keep out of commerce because they are debased by adulteration, and which punishes them (if we may so express ourselves) and the shipper of them. ”
