Lawyer (Partner)

J. Mark Gidley chairs the White & Case LLP Global Antitrust/Competition Practice. His practice focuses on mergers, acquisitions, and cartel cases, often with a transnational focus. Mr. Gidley was the Acting Assistant Attorney General for the US Department of Justice (DOJ) Antitrust Division in 1992-1993. Prior to that, Mr. Gidley served as Deputy Assistant Attorney General for Regulated Industries in the Antitrust Division from 1991-1992. From 1990 to 1991, Mr. Gidley served as Associate Deputy Attorney General under then Deputy Attorney William P. Barr, during the first Bush Administration. During his tenure at the Antitrust Division, Mr. Gidley worked on a number of merger and acquisition investigations, including Bank of America’s acquisition of Security Pacific National Bank. He brought the successful lawsuit under Section 1 of the Sherman Act against the major US domestic air carriers for alleged price fixing and cartel behavior. Mr. Gidley supervised the government grand jury investigation of the treasury bond action market, which resulted in a $28 million asset forfeiture action against Salomon Brothers — at that time the largest antitrust penalty ever in the Division’s history for cartel activity. Mr. Gidley represents parties before the US competition agencies — the FTC and the Antitrust Division — as well as parties in civil and criminal grand jury investigations of pricing conduct, and other potential antitrust violations. His work often features investigations of transnational firms in grand jury investigations, parallel class action suits, and civil investigations of pricing and other competitive practices. Mr. Gidley represents antitrust defendants in multi-forum cases that involve parallel, simultaneous government investigations and multiple civil actions. His cases have often involved investigations by competition agencies outside the United States such as the European Commission, national European authorities, and competition agencies in Canada, Korea, Australia, New Zealand, and Japan. He has significant experience in trying criminal and civil antitrust price-fixing cases and merger cases.
