Amalgamated Food Employees Union Local 590 v. Logan Valley Plaza, Inc.

391 U.S. 308 (1968)

Quick Summary

The Logan Valley Plaza, Inc. (plaintiff) sought to stop The Amalgamated Food Employees Union Local 590 (defendant) from picketing at their shopping center. The union protested Weis Markets for not employing union labor. The primary legal question was whether such picketing could be banned under property and trespass laws without infringing on constitutional rights.

The Supreme Court ruled that banning peaceful picketing in areas that function like a town’s business district violates free speech rights under the First and Fourteenth Amendments. The court reversed a lower court’s decision enjoining such union activities within the mall.

Facts of the Case

Logan Valley Plaza, Inc. (plaintiff) is the proprietor of a substantial shopping center, where Weis Markets, Inc. (defendant) operates a supermarket. The Amalgamated Food Employees Union Local 590 (defendant), upset about Weis employing non-union labor, began to peacefully picket on the shopping center’s property. Logan Valley Plaza, disapproving of this demonstration, sought legal recourse to halt the picketing.

The initial legal action taken by Logan Valley Plaza resulted in an injunction from the Pennsylvania Court of Common Pleas, which was upheld by the Supreme Court of Pennsylvania, effectively banning the union’s picketing on shopping center grounds. This legal battle raised significant First and Fourteenth Amendment questions concerning free speech and property rights, leading to the involvement of the United States Supreme Court.

Procedural Posture and History

  1. Logan Valley Plaza obtained an injunction from the Pennsylvania Court of Common Pleas prohibiting picketing by Amalgamated Food Employees Union.
  2. The Supreme Court of Pennsylvania affirmed the injunction.
  3. The United States Supreme Court granted certiorari to review the case.

I.R.A.C. Format


Whether the prohibition of peaceful picketing on privately owned shopping center property violates the First and Fourteenth Amendments of the United States Constitution.

Rule of Law

Peaceful picketing on property that is open to the public, such as streets and sidewalks, is protected by the First Amendment, and access cannot be denied solely based on property ownership when the property serves a public function akin to a municipality’s business district.

Reasoning and Analysis

The Supreme Court’s analysis hinged on the principle that certain private properties take on attributes of a public thoroughfare or business district and thus should be accessible for First Amendment activities. Drawing parallels to earlier cases like Marsh v. Alabama, which dealt with a company-owned town, the Court found that Logan Valley Mall, similar to Chickasaw in Marsh, had become a de facto public space due to its openness and accessibility to the general public.

Consequently, it ruled that state trespass laws could not be applied to unjustifiably hinder expressive activities related to the shopping center’s operations.

The Court emphasized that while private property rights are significant, they become limited when a property owner invites the public in large numbers for commercial purposes. The substantial similarity between the shopping center and a town’s business block meant that preventing picketing in such spaces would unjustly obstruct communication essential to exercise First Amendment rights.


The Supreme Court reversed the decision of the Supreme Court of Pennsylvania and remanded for further proceedings consistent with its opinion that prohibiting picketing in the mall’s premises violated First Amendment rights.

Key Takeaways

  1. Private property that functions as a public space cannot be used to prohibit First Amendment activities such as peaceful picketing.
  2. The Supreme Court can reverse lower court decisions that conflict with constitutional protections of free speech.
  3. Shopping centers like Logan Valley Mall are considered equivalent to public business districts for First Amendment purposes.

Relevant FAQs of this case

What legal protections are afforded to peaceful assembly in privately-owned spaces that mimic public squares?

Peaceful assembly in privately-owned spaces that function as traditional public squares, such as shopping malls or plazas, may be protected under the First Amendment when those spaces become the functional equivalent of a public forum. However, this protection is not absolute and must be balanced against the property owner’s rights. Restrictions on assembly must be content-neutral, narrowly tailored to serve a significant government interest, and leave open ample alternative channels for communication.

  • For example: A privately-owned park which regularly permits the public to gather and socialize may have to accommodate protests or rallies, similar to public parks, unless there are compelling reasons and provided rules to restrict such activities.

How do courts determine whether a private property is a public forum for First Amendment activities?

Courts consider several factors to determine if private property is a public forum for First Amendment activities: the property’s physical characteristics, the primary use and purpose of the property, policies and practices of the property owner, and whether the public is invited and encouraged to use the property for expressive activities. If these factors together show that the property has been opened up for use by the public in a manner similar to a traditional public forum, it may be treated as such.

  • For example: A large shopping center that has sidewalks, benches, and an open invitation for the community to congregate may be deemed a public forum if these elements together create an environment conducive to expressive activities.

In what ways can private property owners legally manage First Amendment activities on their premises?

Private property owners can manage First Amendment activities by implementing reasonable time, place, and manner restrictions. These restrictions must not be based on content or viewpoint but should be designed to minimize interference with business operations or prevent safety hazards. Owners can designate specific areas for speech activities or establish certain hours during which such activities are allowed.

  • For example: A shopping mall may allow pamphleting or petitioning in designated areas away from store entrances during off-peak hours, thereby managing expressive activity without outright prohibitions.
