United States v. Simpson — Opinion of the Court
“ We think the question should have been answered the other way. The evil against which the statute was directed was the introduction of intoxicating liquor into a prohibition state from another state for purposes other than those specially excepted-a matter which Congress could and the states could not control. Danciger v. Cooley, 248 U.S. 319, 323, 39 Sup. Ct. 119, 63 L. Ed. 266. The introduction could be effected only through transportation, and whether this took one form or another it was transportation in interstate commerce. ”
