Sherman Antitrust Act

Sherman Antitrust Act, basic federal enactment regulating the operations of corporate trusts, passed by the U.S. Congress in July 1890, through the efforts of Senator John Sherman of Ohio. The act declared illegal “every contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States, or with foreign nations.” Criminal penalties were provided for violators of the law, and aggrieved persons were entitled to recover three times the amount of losses suffered as a result of the violation. The Sherman Act has been amended and supplemented by several subsequent enactments. Most notable among these enactments was the Clayton Antitrust Act of 1914. See Monopoly; Trusts.
