Supplemental brief of the United States Department of Justice, Federal Trade Commission, Department of State, and Department of Commerce before the U.S. Court of Appeals for the Seventh Circuit further addressing the proper application of the provisions of the Foreign Trade Antitrust Improvements Act of 1982, 15 U.S.C. § 6a, which parallel those of Section 5(a)(3) of the FTC Act, 15 U.S.C. § 45(a)(3). While acknowledging the concern expressed by some foreign governments about the potential collision between foreign and domestic antitrust law associated with the extraterritorial application of federal statutes, the brief notes that it is generally accepted that the Sherman Act applies to foreign conduct meant to produce and producing effects in the United States. By making such conduct subject to the Sherman Act only under certain conditions, Congress struck a balance that protects the country’s commerce and consumers against substantial anticompetitive harm, even when it has foreign origins, while avoiding unreasonable interference with the regulation of foreign markets by other countries.
