Mark Gidley chairs the White & Case global Antitrust/Competition Practice, which is the only such practice to have been named Competition Group of the Year for the past six years by Law360. His practice focuses on mergers and acquisitions, cartel cases, class actions, and pharmaceutical antitrust cases, with an emphasis on trying antitrust cases.
Mr. Gidley represents parties before the US competition agencies—the FTC and the Antitrust Division—as well as parties in criminal grand jury and civil 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 parallel investigations by competition agencies outside the US such as the European Commission, national European authorities, and competition agencies in Canada, Mexico, Korea, Australia, New Zealand, Taiwan, Brazil and Japan. In addition to his US trial work, he has worked on evidentiary hearings or trials in the EC, Korea and Australia. His cartel cases have established fundamental due process rights for companies and individuals. In criminal cartel investigations, Mr. Gidley has represented corporate clients and individuals in a variety of industries, including auto parts, oil and gas leasing, air cargo, defense contracting, ocean shipping, beverages, graphite electrodes, DRAM and LCD.
Mr. Gidley is among the most experienced lawyers in the US in trying criminal and civil antitrust cases, whether involving claims of price-fixing, monopolization, or stemming from a merger. His US trial victories include: wins over the US DOJ in Stolt I and Stolt II (criminal cartel), Ian Norris (criminal cartel/obstruction), and Sungard (merger) and AgriMark (merger); trial victory over the FTC in FTC v. Schering-Plough (the first reverse payment trial in the US); trial victories over class actions and opt-out litigants (Toshiba LCD $2.7 billion direct purchaser class action; Toshiba LCD $2.4 billion Best Buy trial, Heveafil). His cases have shaped modern antitrust law in mergers, cartels, monopolization and pharma antitrust.
His experience in transnational transactions spanning multiple and often conflicting antitrust regimes includes being co-editor of the Worldwide Merger Notification Requirements, a comprehensive compendium of global merger filing regimes in more than 210 jurisdictions, which is based on the firm's global merger clearance experience.
