n. acts adopted by Congress to outlaw or restrict business practices considered to be monopolistic or which restrain interstate commerce. The Sherman Antitrust Act of 1890 declared illegal "every contract, combination…or conspiracy in restraint of trade or commerce" between states or foreign countries. The Clayton Antitrust Act of 1914, amended by the Robinson-Patman Act of 1936, prohibits discrimination among customers through pricing and disallows mergers, acquisitions or takeovers of one firm by another if the effect will "substantially lessen competition." Interstate commerce includes commerce within a state which affects the flow of that commerce, thus making it pretty broad. There are also some state laws against restraint of trade. The Antitrust Division of the U.S. Department of Justice enforces for the federal government, but private lawsuits to halt antitrust activities have become increasingly popular, particularly since attorney's fees are awarded to the winning party. This is a legal specialty which has kept some industries relatively honest and made some lawyers wealthy.
