Supreme Court of the United States

United Brotherhood of Carpenters and Joiners of America v. United States

March 10, 1947330 U.S. 395

Summary

The Supreme Court reversed the convictions of the defendants and remanded the cases, holding that § 6 of the Norris‑LaGuardia Act requires clear proof of actual participation, authorization, or ratification before an association can be held liable for unlawful acts of its officers or members in a labor dispute, and that the trial courts must give jury instructions reflecting this limitation. The decision also affirmed that employer groups may be retried under this interpretation.

Holding

  • Whether § 6 of the Norris‑LaGuardia Act limits the liability of labor unions and employer associations for the unlawful acts of their officers or members in a conspiracy that violates the Sherman Act. Section 6 requires clear proof of actual participation, authorization, or ratification before an association may be held liable for the unlawful acts of its officers or members in a labor dispute; therefore the trial courts must instruct juries on this limitation.
