United States v. Bass

1971-12-20

Headline: Limits federal gun ban for felons by requiring an interstate-commerce link, making it harder for prosecutors to convict for mere possession without proving an interstate connection.

Holding: The Court holds that the federal law banning felons from receiving, possessing, or transporting firearms must be read to require proof that each possession, receipt, or transport involved interstate commerce, so the possession conviction cannot stand.

Real World Impact:

Requires prosecutors to show interstate-commerce link to convict felons for firearm possession.
Preserves state authority over ordinary local gun possession prosecutions.

Topics: gun laws, interstate commerce, criminal prosecutions, state versus federal authority

Summary

Background

A man previously convicted of a felony in New York was tried in federal court for possessing a pistol and later a shotgun under Title VII of the Omnibus Crime Control and Safe Streets Act, 18 U.S.C. App. §1202(a). The indictment did not allege, and the prosecution did not try to prove, that the guns were "in commerce or affecting commerce." The Second Circuit reversed his conviction, and the Supreme Court agreed to resolve a split among appeals courts about how to read the statute.

Reasoning

The central question was whether the phrase "in commerce or affecting commerce" applies to the verbs "receives" and "possesses" as well as to "transports." The Court found the statute ambiguous. Because the statute imposes criminal penalties and a broad reading would intrude on traditional state criminal jurisdiction, the Court applied the rule of lenity and the clear-statement principle protecting federal-state balance. It adopted the narrower reading that requires a commerce nexus for possession and receipt, and it set aside the possession conviction because the Government failed to show an interstate-commerce link.

Real world impact

The decision means federal prosecutors must prove an interstate-commerce connection before convicting felons for mere possession of firearms, for example by showing the gun was moving across state lines or previously traveled in interstate commerce. The Court left open the separate constitutional question whether Congress may criminalize mere possession in every circumstance. The ruling resolves a circuit conflict and preserves a clearer boundary between state and federal criminal enforcement.

Dissents or concurrances

Justice Brennan joined the judgment but did not join Part III about how to prove the commerce link. Justice Blackmun, joined by the Chief Justice, dissented, arguing the statute and legislative history show Congress intended to ban all possessions by felons without requiring an interstate link.
