Antitrust and Competition


Scott D. Hammond is a partner in the Washington, D.C. office of Gibson, Dunn & Crutcher, LLP and co-chair of the firm's Antitrust and Competition Practice Group.


Mr. Hammond brings exceptional experience to companies and executives subject to investigations by the U.S. Department of Justice's Antitrust Division and the world's other major competition enforcement authorities.  Mr. Hammond is internationally recognized by senior competition officials and private practitioners as one of the leading figures behind the globalization of cartel enforcement.  His knowledge of and experience with the policies, practices and strategies of U.S. and foreign competition authorities positions him to represent companies and their executives in the potentially high-stakes arena of international cartel investigations and litigation.

Before joining Gibson Dunn, Mr. Hammond served as a U.S. Department of Justice prosecutor for 25 years.  Most recently, he served for eight years as the Antitrust Division's Deputy Assistant Attorney General for Criminal Enforcement - the highest ranking career lawyer in the Antitrust Division.  In that capacity, he was responsible for supervising all of the Department of Justice's domestic and international criminal antitrust investigations as well as overseeing all of the criminal antitrust litigation nationwide.  Mr. Hammond oversaw the work of more than 100 federal prosecutors and led criminal prosecutions in a wide range of industries, including auto parts, LIBOR, municipal bonds, LCD panels, air transportation, real estate foreclosure auctions, construction, chemicals and coastal freight.  He personally tried criminal antitrust cases and has directed the litigation of dozens of jury trials.  In addition, he assisted in overseeing all of the Antitrust Division's criminal appellate work between 2005 and 2013.  More than 20 of his policy papers covering all aspects of antitrust investigations and prosecutions are currently listed on the Department of Justice's website.  

Mr. Hammond assists clients in antitrust and white-collar crime compliance, crisis management and government investigations across all industry sectors.  Mr. Hammond provides clients with know-how on the Department of Justice's latest strategies for monitoring and uncovering antitrust and related federal violations which can also be employed by companies to design effective compliance programs as well as to ensure early detection of violations.  Timely detection can result in a complete pass from prosecution for companies and their executives under the Antitrust Division's Corporate Leniency Program that Mr. Hammond helped implement and that he oversaw while at the Division.  In addition, Mr. Hammond was instrumental in the design and implementation of similar leniency programs in dozens of jurisdictions around the world. 

Mr. Hammond's practice focuses on the representation of clients in cross border investigations running in parallel with U.S. Department of Justice investigations. During his tenure at the Antitrust Division, he was the principal point of contact for cartel matters with senior competition officials abroad and oversaw the Department's coordination of joint investigations with numerous jurisdictions, including the European Union, Australia, Brazil, Canada, Chile, Germany, Japan, Korea, Mexico, The Netherlands, New Zealand, Singapore, South Africa, Switzerland, and the United Kingdom.  As a result, Mr. Hammond is well versed in the anti-cartel enforcement investigative powers as well as the policies and practices of every major competition enforcement authority.  His experience allows clients to create a comprehensive and integrated global strategy to assess and mitigate their potential exposure to criminal, civil and administrative sanctions by enforcement agencies working in tandem across the globe.

Companies and high-level executives that are subject to U.S. Department of Justice criminal antitrust investigations will routinely face private damage lawsuits in the United States and, with growing frequency, elsewhere.  Mr. Hammond assists clients in navigating the intersection of government and private damage proceedings and litigation. In addition, the U.S. Department of Justice often brings criminal antitrust charges in combination with other federal crimes.  While with the Department, Mr. Hammond supervised more than a hundred prosecutions involving wire fraud, mail fraud, FCPA, money laundering, commercial bribery, obstruction of justice and other federal crimes.

Chambers Global 2017 named Mr. Hammond a leading attorney in the area of USA Antitrust: Cartel. In 2016, Mr. Hammond was nationally recognized by Chambers USA as a leading attorney in the areas of Antitrust and Antitrust: Cartel. He was recently selected by his peers for inclusion in The Best Lawyers in America© 2016 in the field of Antitrust Law and was also named a 2016 "Litigation Star" by Benchmark Litigation: The Definitive Guide to America's Leading Litigation Firms and Attorneys.  In 2015, the National Law Journal named Mr. Hammond to its Regulatory & Compliance Trailblazers list for his role in developing and implementing the DOJ's Corporate Leniency Program during his time as the Deputy Assistant Attorney General for Criminal Enforcement. In 2015, he was also featured in Global Competition Review's International Who's Who: Competition Lawyers.  While with the Department of Justice, Mr. Hammond received the Presidential Rank Award (the highest honor conferred on federal government executives), the Attorney General's Distinguished Service Award, the Antitrust Division's Award of Distinction (twice) as well as numerous other citations.

Scott Hammond - Gibson, Dunn & Crutcher LLP

Within: Cartel

Gibson, Dunn & Crutcher LLP excels in US and global cartel investigations, and San Francisco’s Trey Nicoud is acting for NEC Tokin and NEC Tokin America in the DOJ’s investigation into the capacitor industry, as well as in follow-on actions pending in the Northern District of California. Other key representations include matters concerning cathode ray tubes (CRTs) and TFT-LCD panels, automotive parts and the foreign exchange markets. The group is jointly led by Washington DC-based Scott Hammond (whose 25-year career as a DOJ prosecutor included an eight-year spell as the Antitrust Division’s deputy assistant attorney general for criminal enforcement) and Sean Royall as well as New York-based Peter Sullivan and Daniel Swanson in Los Angeles. Eric Stock, who was formerly chief of the Antitrust Bureau at the New York Attorney General’s office, joined the firm in 2016. Cynthia Richman is a strong up-and-coming lawyer.

Civil litigation/class actions

Within: Civil litigation/class actions

Gibson, Dunn & Crutcher LLP’s outstanding cartel investigations practice makes it a particularly compelling choice for associated civil litigation, although its antitrust litigation practice extends beyond that to also include standalone high-value private antitrust matters (where there is no government agency involvement) and contentious merger-related work. In a notable highlight, Jeffrey Thomas (Orange County), Samuel Liversidge, Jay Srinivasan and Rod Stone assisted HP with obtaining a $3bn damages award against Oracle (representing the largest single-plaintiff verdict in US history) in a high-profile case arising from the latter’s decision to stop developing software for the client’s Itanium servers. In another matter, Daniel Swanson, Joshua Lipton (Washington DC) and others defended Nasdaq OMX in litigation related to the pricing of market data products. Swanson jointly heads the practice with New York-based Peter Sullivan, Dallas-based Sean Royall and Washington DC’s Scott Hammond. In 2016, Eric Stock joined the firm in New York, having previously served as chief of the Antitrust Bureau at the New York Attorney General’s office. Washington DC-based Joshua Soven is another name to note. Named lawyers are based in Los Angeles except where otherwise indicated.

Merger control

Within: Merger control

Gibson, Dunn & Crutcher LLP’s sizable US and international footprint makes it well positioned to handle the full spectrum of antitrust issues associated with domestic and cross-border transactions. In 2016, Joshua Lipton and Joshua Soven were part of a cross-border team assisting Marriott with obtaining global antitrust clearance of its $13.8bn merger with Starwood. In another matter, Soven and others are acting as global antitrust counsel to St Jude Medical in its $25bn merger with Abbott Laboratories. Eric Stock joined the New York office, having served as chief of the Antitrust Bureau at the New York State Attorney General’s office. Scott Hammond, Dallas- and Washington DC-based Sean Royall, New York’s Peter Sullivan and Los Angeles’s Daniel Swanson co-chair the practice. Counsel Andrew Cline specializes in HSR filings. Cynthia Richman is a rising talent. Unless otherwise stated, named attorneys are based in Washington DC. Since publication, Joel Sanders has retired.
