Whether the evidence of Japanese cartelization, export check prices, and the five-company distribution rule independently supported respondents' antitrust-damages claims.
Holding
No. Those practices could not, by themselves, establish a cognizable antitrust injury to the American-manufacturer respondents.
Reasoning
Antitrust damages require injury of the type the antitrust laws are designed to prevent. Respondents could not recover merely because petitioners allegedly charged supracompetitive prices in Japan, because American antitrust law does not regulate competitive conditions in a foreign nation's domestic economy absent a relevant effect on United States commerce.
Nor could respondents recover for agreements that raised prices or restricted output in the United States, including minimum export prices or distributor limits. Although such agreements may violate antitrust law, rival manufacturers ordinarily benefit rather than suffer injury when competitors raise the market price. The allegedly actionable theory therefore had to be a conspiracy to monopolize the United States market through predatory, below-market pricing.
