Arnold & Porter


United States: Antitrust


Within: Cartel

Arnold & Porter’s practice was boosted thanks to three notable individuals re-joining the firm; new global antitrust head Debbie Feinstein moved from the FTC, where she was director of the Bureau of Competition. In addition, Bill Baer (a former assistant attorney general for antitrust and acting associate attorney general) and Sonia Pfaffenroth (a former deputy assistant general for civil and criminal operations) arrived from the DOJ. James L. Cooper, James W. Cooper and Wilson Mudge are representing MinebeaMitsumi in civil litigation arising from the DOJ’s criminal prosecution of alleged price-fixing of ball bearings. Nucor, Visa and Philip Morris USA are other clients. Jonathan Gleklen leads the US antitrust practice.

  • The role of arbitrators in EU antitrust law

    In May 2014, it will be ten years since Regulation No 1/2003 entered into force. When the legislator of the European Union adopted this Regulation on 16 December 2002, its main objective was to decentralise the enforcement of the two main provisions of EU antitrust law, Articles 81 and 82 of the Treaty establishing the European Community (now Articles 101 and 102 of the Treaty on the Functioning of the European Union (TFEU)).
