Giboney v. Empire Storage & Ice Co.

Background

A group of about 160 retail ice delivery drivers and handlers in Kansas City organized a drive to get nonunion peddlers to join their union. When most nonunion peddlers refused, the union pressured local wholesale ice distributors to stop selling to nonunion sellers; only Empire Storage and Ice Company refused. The union then picketed Empire’s place of business to force it to stop selling to nonunion peddlers. Missouri law criminalized agreements to refuse to sell to certain buyers and allowed civil damages. Empire sued and obtained an injunction stopping the picketing; state courts upheld that injunction.

Reasoning

The Court addressed whether a state may apply its anti–trade‑restraint law to union activities and forbid picketing that is part of an effort to restrain trade. Relying on prior decisions, the Court said states may regulate combinations that limit competition and need not exempt unions. The Court found the picketing was an essential and inseparable part of a plan to coerce Empire into violating Missouri’s law, not merely isolated speech. Because the picketing was integral to unlawful conduct, the First Amendment did not protect it from an injunction, and the state’s enforcement power prevailed.

Real world impact

The decision lets states apply their trade‑restraint laws to union campaigns that use economic pressure to restrict sales. Businesses can seek injunctions when picketing is directly tied to an unlawful concerted plan to exclude competitors or customers. Unions remain free to speak, but speech that is an essential tool of an otherwise illegal conspiracy can be restrained. The ruling affirms state authority to choose how to regulate local trade practices and limits a union’s ability to use picket lines to force illegal agreements.
