Clayton Antitrust Act

The Clayton Antitrust Act of 1914 (Pub.L. 63–212, 38 Stat. 730, enacted October 15, 1914, codified at 15 U.S.C. §§ 12–27, 29 U.S.C. §§ 52–53), was a part of United States antitrust law with the goal of adding further substance to the U.S. antitrust law regime; the Clayton Act sought to prevent anticompetitive practices in their incipiency. That regime started with the Sherman Antitrust Act of 1890, the first Federal law outlawing practices considered harmful to consumers (monopolies, cartels, and trusts). The Clayton Act specified particular prohibited conduct, the three-level enforcement scheme, the exemptions, and the remedial measures.

Like the Sherman Act, much of the substance of the Clayton Act has been developed and animated by the U.S. courts, particularly the Supreme Court.
