Who's Who Legal Competition: Lawyers

D Jarrett Arp is a partner in the Washington, DC office of Gibson, Dunn & Crutcher, where his practice focuses on antitrust and competition law counselling, investigations, and litigation before US trial and appellate courts. A member of the Virginia, District of Columbia, and Brussels Bars and a solicitor of England and Wales, Mr Arp has represented companies and individuals in international competition law matters, including numerous significant cartel investigations, over the course of 20 years.   

Among other recognitions, Mr Arp is the co-chair of the ABA/IBA international cartel workshop (2012, 2014 and 2016), the preeminent international cartel enforcement conference worldwide, and for years has been ranked as a leading antitrust lawyer by Chambers USA, Who’s Who Legal: Competition, PLC’s Which Lawyer?, Euromoney Legal Group’s Guide To The World’s Leading Competition & Antitrust Lawyers, US News & World Report’s Best Lawyers, and the peer-selected Best Lawyers in America, among others. Chambers describes Mr Arp as “a ‘fantastic lawyer,’ particularly recognised for his cartel expertise,” who is “a veteran litigator, proven at both trial and appellate level[s].”

Mr Arp's representative matters include the defence of multinational companies as well as individuals in connection with more than 20 international cartel investigations and antitrust-related US grand jury investigations – including plea negotiations and/or leniency applications in the United States, the European Union, Canada, the United Kingdom, Australia, Japan, Brazil, Switzerland and a variety of other jurisdictions. Mr Arp has also secured several significant declinations, in which antitrust authorities ultimately declined to bring charges and closed their investigations. Most recently, Mr Arp played a leading role in Gibson Dunn’s representation of UBS AG in the LIBOR and Foreign Exchange investigations.

Mr Arp co-authored the antitrust criminal investigations chapter of a leading treatise, Defending Corporations and Individuals in Government Investigations (West, 2011 and 2013 editions). During  2002–2010, he served as the editor-in-chief of Antitrust Report, the quarterly US law periodical published by Mathew Bender and Lexis/Nexis. He has also served as a member of the ABA’s international cartel taskforce (2012–2014), associate editor of the ABA’s Antitrust magazine (1999–2008), editor of the ABA’s First Supplement to Competition Laws Outside the United States (2005), and an adjunct professor of law at the Washington & Lee University Law School (teaching antitrust; 2002–2005). 

Mr Arp previously served as an officer with the United States Army’s 101st Airborne Division and as a Special Assistant United States Attorney for the Middle District of Tennessee. Mr Arp received his law degree in 1991 from William and Mary, where he served as an executive editor of the William and Mary Law Review. He earned a Bachelor of Arts degree in political science from Wheaton College in 1988.

WWL says: Jarrett Arp is considered a “top-notch” litigator by peers who praise his excellent representation of clients before the US trial and appellate courts.
