United States v. Kahriger

Background

The dispute was between the United States and a person accused of being in the business of accepting wagers who failed to register and pay an occupational tax under the Revenue Act of 1951. The statute imposed a 10% excise on wagers, a $50 special tax, and required registrants to give names, addresses, and business locations. The District Court dismissed the charge, holding the law invaded state police power and violated the Fifth Amendment; other district courts had reached opposite results.

Reasoning

The core question was whether Congress could impose the wagering tax and require registration, or whether that was really an attempt to punish state crimes or to force self-incrimination. The majority reversed the dismissal. It relied on earlier decisions saying Congress may impose taxes that also discourage activity, found the wager tax applied whether or not state law made the conduct criminal, and concluded the registration information was plainly related to collecting the tax. On self-incrimination, the Court said the privilege protects past disclosures, not a requirement to comply with future business conditions, and that any specific privileged answers could be asserted when required.

Real world impact

The decision allows federal enforcement of the wagering excise and registration requirements. People who run betting businesses may be required to identify themselves and pay federal taxes on wagers. The ruling leaves open political remedies in Congress and highlights tensions between federal revenue powers and state regulation.

Dissents or concurrances

Justice Jackson concurred with reservations, warning the law approaches constitutional limits. Justices Black and Frankfurter dissented, arguing the law could coerce self-incrimination and improperly intrude on state police powers, respectively.
