Supreme Court of the United States

Connell Construction Co., Inc. v. Plumbers & Steamfitters Local Union No. 100, United Association of Journeymen &…

June 2, 1975421 U.S. 616

Summary

The Court held that the subcontracting agreement between Local 100 and Connell Construction is not immune from federal antitrust laws and therefore may be subject to a Sherman Act claim, while affirming that Texas state antitrust law is pre‑empted by federal labor policy. The judgment was reversed in part, affirmed in part, and remanded for determination of whether the agreement actually violates the Sherman Act. Two dissenting opinions argued that the union’s conduct should be governed exclusively by labor law remedies.

Holding

  • Whether the subcontracting agreement is exempt from federal antitrust laws. The agreement is not exempt; it is subject to the Sherman Act.
  • Whether Texas state antitrust law is pre‑empted. State antitrust law is pre‑empted by federal labor policy and the NLRA.
