Federal Antitrust Laws

State Antitrust Laws


While antitrust law is primarily federal in character, most states have also passed state antitrust laws modeled on the federal Sherman Antitrust Act of 1890 and the Clayton Antitrust Act of 1914. A state attorney general may enforce both federal and state antitrust laws, and attorneys general often collaborate with their counterparts in other states to bring large suits.
