Summary

Ruppert v. Caffey — Opinion of the Court

If the war power of Congress to effectively prohibit the manufacture and sale of intoxicating liquors in order to promote the nation's efficiency in men, munitions and supplies is as full and complete as the police power of the states to effectively enforce such prohibition in order to promote the health, safety and morals of the community, it is clear that this provision of the Volstead Act is valid and has rendered immaterial the question whether plaintiff's beer is intoxicating.

Ruppert v. Caffey — Opinion of the Court

In other words, it clearly appears that a liquor law, to be capable of effective enforcement must, in the opinion of the Legislatures and courts of the several states, be made to apply either to all liquors of the species enumerated, like beer, ale or wine, regardless of the presence or degree of alcoholic content; or if a more general description is used, such as distilled, rectified, spirituous, fermented, malt, or brewed liquors, to all liquors within that general description regardless of alcoholic content;b or to such of these liquors as contain a named percentage of alcohol

Ruppert v. Caffey — Opinion of the Court

May the plaintiff show as a basis for relief that the beer manufactured by it with alcoholic content not greater than 2.75 per centum in weight and 3.4 per centum in volume is not in fact intoxicating? The government insists that the fact alleged is immaterial since the passage of the Volstead Act by which the prohibition of the manufacture and sale is extended to all beer and other malt liquor containing as much as one-half of 1 per centum of alcohol by volume.
