No Oil Producing and Exporting Cartels Act (NOPEC) is federal legislation that would make foreign oil-producing cartels (such as OPEC) subject to American antitrust law that prohibits cartels. Specifically, the bill declares that oil-producing foreign states do not have sovereign immunity and may be sued under the Sherman Antitrust Act.
In 2007, NOPEC passed both Houses of Congress by veto-proof margins.[1][2]
