Dallas General Drivers, Warehousemen and Helpers v. Wamix, Incorporated of Dallas

Summary

The Texas Supreme Court affirmed the lower courts' judgment, holding that the state court had jurisdiction to grant ancillary injunctive relief in a damages suit because the Union failed to show that the National Labor Relations Board had exclusive jurisdiction, and it modified the temporary injunction by dissolving the provisions prohibiting insulting language and statements about strike breakers while leaving the picketing restriction in place. Justice Smith dissented, arguing that the state court lacked jurisdiction to enjoin the labor practices.
