National Prohibition Cases

Background

Several states, state officials, businesses, and individuals brought seven lawsuits challenging the Eighteenth Amendment and the Volstead Act, the federal law written to enforce it. Two cases were filed directly in the Supreme Court and the others came from federal district courts. Each plaintiff asked a court to stop the government from enforcing the Volstead Act against manufacture, sale, or transport of alcoholic beverages.

Reasoning

The Court addressed whether the Amendment was properly adopted and how far section two’s phrase “concurrent power” reaches. The majority held the Amendment valid and now part of the Constitution. It said Section One’s national prohibition is operative throughout U.S. territory and overrides any law that permits the banned conduct. The Court interpreted Section Two to allow Congress broad power to enforce the ban — territorially coextensive with the prohibition and not dependent on state approval — and upheld the Volstead Act’s definition of alcoholic beverages as within those enforcement limits. The Court dismissed the two original bills, reversed one injunction, and affirmed four injunction denials, allowing wider federal enforcement.

Real world impact

The ruling clears the way for federal enforcement of nationwide alcohol prohibition under the Volstead Act and affects state laws, manufacturers, sellers, and transporters across state lines. It lets federal officers and courts act even where states have not adopted or have adopted different rules. The decision is final on these questions unless altered by later rulings or amendments.

Dissents or concurrances

Several Justices wrote separately. Chief Justice White agreed with the outcome but lamented the lack of detailed reasoning. Justices McKenna and Clarke dissented, arguing the word “concurrent” should require joint state–federal action and warning the majority’s reading reduces state authority.
