Radiant Burners, Inc. v. Peoples Gas Light & Coke Co.

Background

A manufacturer in Lombard, Illinois makes and sells a ceramic gas "Radiant Burner" in interstate commerce. The maker sued a national trade association that tests and labels burners and ten member companies, including gas utilities, saying they conspired to stop sales by refusing to supply gas for burners that lack the association’s approval. The maker asked for an injunction and threefold damages. Lower courts dismissed the complaint for failure to state a claim, and the maker appealed to the Supreme Court.

Reasoning

The Court asked whether the maker’s complaint, if true, stated a legal claim. It relied on prior rulings and explained that a coordinated refusal to supply a necessary input—here, gas for certain burners—can be one of the kinds of restraints that the Sherman Act forbids automatically. Because the alleged conspiracy would block the normal flow of interstate commerce and effectively exclude the burner from the market, the complaint met the requirements to allege an illegal agreement and resulting injury that a private plaintiff may challenge.

Real world impact

The Court reversed the lower-court dismissal and sent the case back for further proceedings, meaning the maker can pursue damages and an injunction. The ruling makes clear that coordinated boycotts or refusals to supply essential inputs can state a claim under federal antitrust law, even when the immediate victim is a single competitor. The decision is not a final finding on facts; the case will continue in the lower courts to resolve evidence and remedies.
