Facts
- Vogt, Inc. operated a small gravel pit in Oconomowoc, Wisconsin, employing roughly 15–20 workers.
- The International Brotherhood of Teamsters, Local 695 and affiliated unions unsuccessfully attempted to organize Vogt’s employees.
- The unions began peaceful picketing at the plant entrance with signs stating the workers were not “100% affiliated with the A.F.L.”
- The picketing led several trucking companies’ drivers to refuse to haul goods to and from the plant, causing substantial business harm to Vogt.
- Vogt sought and obtained a state-court injunction barring picketing near the premises, displaying signs suggesting a labor dispute, and inducing others to refuse transportation services.
- On rehearing, the Wisconsin Supreme Court sustained the injunction, finding the picketing sought to coerce Vogt to pressure employees to join the unions, which Wisconsin treated as unlawful under its labor policy (including Wis. Stat. § 111.06(2)(b)).
Issues
- Whether the First and Fourteenth Amendments permit a state to enjoin peaceful picketing when the picketing’s purpose is to pressure an employer to coerce employees to join a union, contrary to state labor policy.
- How far the Fourteenth Amendment limits state authority to enjoin labor picketing used to achieve ends that state law deems unlawful.
Decision
- The U.S. Supreme Court affirmed the Wisconsin Supreme Court’s judgment sustaining the injunction.
- The Court held that a state may enjoin peaceful picketing when it is conducted for an unlawful purpose under state law.
- Accepting the state court’s finding of purpose, the Court concluded Wisconsin could prohibit picketing intended to coerce the employer to interfere with employees’ protected freedom to join or not join a union.
- The Court rejected the view that peaceful picketing receives the same constitutional treatment as pure speech because picketing combines communication with coercive economic effects on third parties.
Legal Principles
- Peaceful picketing, though expressive, is “conduct plus speech,” allowing broader regulation than restrictions on speech alone.
- Consistent with the Fourteenth Amendment, a state may enjoin peaceful picketing aimed at accomplishing objectives the state may lawfully forbid under declared public policy.
- When a state court finds that picketing’s objective is unlawful under state labor law (e.g., coercing an employer to pressure employees regarding union membership), an injunction to enforce that policy may be constitutionally permissible.
Conclusion
The Court upheld a state injunction against peaceful union picketing where the picketing was found to have the unlawful objective of coercing the employer to interfere with employees’ statutory freedom of choice about union membership, holding that such regulation does not violate the First and Fourteenth Amendments.
