United States: Mayer Brown Appoints Don Klawiter As Antitrust Partner In Washington, DC
Last Updated: October 12 2007

October 10, 2007 - International law firm Mayer Brown today announced that Donald C. Klawiter has joined the firm’s Antitrust & Competition Practice in Washington, DC as a partner.  Mr. Klawiter, 57, most recently served as a senior member of the antitrust practice at Morgan, Lewis & Bockius LLP. 

Mr. Klawiter is a widely recognized leader in the national and international antitrust bar for his expertise in dealing with criminal antitrust investigations and cases, and related civil litigation.  Mr. Klawiter has defended corporations and executives from six different continents in grand jury investigations and prosecutions, and he has served as international coordinating counsel in many multi-jurisdictional proceedings.  He has substantial antitrust trial experience as a prosecutor and as defense counsel.  From 1975 to 1986, Mr. Klawiter held senior supervisory positions with the Antitrust Division of the U.S. Department of Justice. 

Commented Mayer Brown Vice Chairman Kenneth S. Geller, “We are extremely pleased to welcome a leading lawyer such as Don Klawiter to Mayer Brown.  Don’s deep international experience, and his extensive experience leading internal investigation teams often in crisis investigations, will complement what is already an exceptionally strong antitrust and competition law practice that we have established in the U.S. and Europe.”

Also joining the practice as Counsel will be Jennifer M. Driscoll, 37, whose practice at Morgan Lewis has focused on antitrust litigation and counseling, and who has represented clients in international cartel investigations, merger investigations before the European Commission, and Sherman Act cases in federal courts.

“We are very pleased both Don and Jennifer will be joining us,” said Washington, DC office Partner-In-Charge Peter Scher.  He continued, “Clearly, they bring a level of sophistication and expertise that will be of great value and benefit to our clients, no matter what their industry or where they do business.  Don Klawiter’s experience and international reputation, combined with Mayer Brown’s international platform, make a great match.”

Mr. Klawiter chaired the Section of Antitrust Law of the American Bar Association from 2005 to 2006, and is current Chair of the International Cartel Task Force.  He has been a regular speaker at, and organizer of, major antitrust programs in the United States, Canada, England, Germany, Belgium, Italy, Austria, Japan, Australia and South Africa.  He has testified before the International Competition Policy Advisory Committee (ICPAC), before the U.S. Sentencing Commission and before the U.S. Senate Committee on the Judiciary.

“I am delighted to be joining Mayer Brown’s outstanding Antitrust & Competition Practice,” commented Mr. Klawiter.  He added, “This firm has a superb international platform to be the ‘one-stop shop of choice’ for corporate clients worldwide for antitrust issues.  It is gratifying to be part of that team and Jennifer and I look forward to making a significant long-term contribution.”

Ms. Driscoll has previously worked at law firms in New York, Paris and London.  She is vice-chair of the ABA Antitrust Law Section’s Sherman Act Section Two Committee.  She has contributed a chapter to a forthcoming ABA Monopolization Handbook and has published articles in numerous ABA specialty antitrust reports.  Ms. Driscoll earned her J.D. from the University of Pennsylvania Law School in 2000, where she was the symposium editor for the Journal of International Economic Law
