Whether § 11 of the Clayton Act gives the Federal Trade Commission exclusive authority to enforce § 8, thereby depriving federal district courts of jurisdiction over the Government's suits.
Holding
No. Federal district courts retain jurisdiction to prevent and restrain § 8 violations.
Reasoning
Although § 11 authorizes the Federal Trade Commission to enforce § 8, § 15 expressly gives federal district courts jurisdiction to prevent and restrain violations of the Clayton Act. The Court read those provisions as creating dual, rather than exclusive administrative, enforcement. Its prior Clayton Act decisions likewise recognized Congress's design to permit both administrative and judicial enforcement.
