Summary

Background

A Chicago milk drivers’ union objected to dairies using a “vendor system” that sold to independent vendors and cut union working standards. The dairy company sued the union to stop interference with its sales. A master found extensive violence connected to the dispute — window-smashing, bombings, burnings, wrecked trucks, beatings, and threats — alongside peaceful picketing. The trial court enjoined violence but allowed peaceful picketing; the Illinois Supreme Court ordered a broader permanent injunction against all picketing.

Reasoning

The central question was whether a state court may bar otherwise peaceful picketing when it is entangled with contemporaneous violence. The Supreme Court affirmed the Illinois judgment. It distinguished prior cases that struck down broad statutes banning picketing by noting this was a concrete, fact-based injunction aimed at preventing continuing coercion after widespread violence. The Court said states may rely on detailed findings of past violence to prevent future coercion, and that federal review should not substitute the Court’s judgment for the state court’s factual determinations unless those findings are clearly unwarranted.

Real world impact

The decision lets state courts use injunctions to limit protests near particular stores when those protests are shown to be part of a pattern involving substantial violence. It affects unions, workers, businesses, storekeepers, and customers in local labor disputes. The Court emphasized that such injunctions are justified only while a coercive threat continues and may be modified by state courts or reviewed by higher courts if enforcement exceeds constitutional limits.

Dissents or concurrances

Justices Black and Reed dissented, arguing the injunction was too broad, infringed free speech about matters of public concern, and punished peaceful advocacy for the many because of violence by a few.
