Sea Breeze Salt, Inc. v. Mitsubishi Corp.

(United States Ninth Circuit) – Held that an antitrust lawsuit was barred by the act-of-state doctrine. The plaintiff corporations alleged that a Mexican-government-owned salt production company engaged in an antitrust conspiracy with a Japanese company. Affirming dismissal of the complaint, the Ninth Circuit held that the lawsuit was fundamentally a challenge to Mexico’s determination about the exploitation of its own natural resources and thus was barred by the act-of-state doctrine, which precludes adjudication of the sovereign acts of other nations in U.S. courts.
