Eric’s practice focuses on antitrust litigation and investigations, especially for clients in the pharmaceutical, financial services, high tech, and health care industries. He is a member of Gibson Dunn’s Antitrust and Competition and Litigation Practice Groups.

Eric is a leading antitrust litigator and one of the few attorneys to earn a Band 1 ranking in Antitrust for New York from Chambers USA. Clients describe him as “a phenomenal powerhouse,” who is “a fantastic litigator,” with “complete command of the law” (Chambers USA). Who’s Who Legal referred to him as “an outstanding competition lawyer” who is “highly esteemed by peers,” particularly in pharmaceutical matters. In 2022, 2024, and 2025, Eric was shortlisted for Life Sciences Antitrust Practitioner of the Year by LMG Life Sciences. Eric has also been recognized as a leading antitrust lawyer by Global Competition Review, The Best Lawyers in America®, Law360, Lawdragon, and Benchmark Litigation—underscoring his reputation as one of the foremost advocates in the field.

Eric’s practice involves all aspects of antitrust enforcement, including civil litigation, government investigations, and merger clearance. He frequently is responsible for coordinating a client’s response to antitrust investigations and civil litigation in multiple jurisdictions and proceedings. He has extensive experience litigating class actions and other civil antitrust cases in federal court, including defending clients accused of unlawful monopolization, collusion, and anticompetitive transactions. Eric has particular experience counseling and litigating matters where a client faces antitrust scrutiny as a result of its defense of its intellectual property rights. His litigation experience includes serving as the lead trial lawyer in a pharmaceutical monopolization case in the Southern District of New York, where his trial victory was upheld on appeal by the Second Circuit Court of Appeals.

Eric served for three years as Chief of the Antitrust Bureau at the New York Attorney General’s Office (“NYAG”). In that role, he was responsible for overseeing the enforcement of New York State’s antitrust laws and representing the interests of New York and its consumers in national antitrust matters. During Eric ’s tenure at NYAG, he served as lead counsel and lead trial attorney for New York in several noteworthy antitrust litigation matters and supervised dozens of antitrust investigations led by the state. He also had extensive experience partnering with the U.S. Department of Justice and Federal Trade Commission in joint federal and state investigations of proposed mergers or other business conduct. For example, he served as lead counsel for New York in the successful lawsuit brought by New York and the U.S. Department of Justice challenging an allegedly anticompetitive merger of Manhattan tour bus operators.

During his time at NYAG, Eric regularly worked with other state AG offices throughout the country on antitrust or related complex business litigation issues. In addition, in early 2016, he served as NYAG’s Acting Executive Deputy Attorney General for Economic Justice, a position which supervises much of the office’s business-related affirmative litigation, including cases filed under the Martin Act and state deceptive practices laws.

Eric has recently achieved several important victories for his clients. In a class action brought by purchasers of Eurodollar futures against financial institutions accused of manipulating the LIBOR benchmark, Eric defeated class certification after deposing plaintiffs’ lead economist, leading the briefing, and handling oral argument in both the District Court and Second Circuit. In an action brought against a major branded pharmaceutical company by a competitor alleging that the defendant unlawfully monopolized the market for dry eye medications through the use of bundled discounts, Eric won dismissal on the pleadings. Eric also won a motion to dismiss on behalf of a group of five major New York hospital systems that were accused by a competitor of colluding in violation of the antitrust laws.

Scott D. Hammond, former Deputy Assistant Attorney General for Criminal Enforcement of the U.S. Department of Justice’s Antitrust Division, brings exceptional experience to companies and executives subject to investigations by the U.S. DOJ’s Antitrust Division and the world’s other major competition enforcement authorities.

Scott 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 investigation strategies of U.S. and foreign competition authorities positions him to represent companies and their executives in the potentially high-stakes arena of U.S. DOJ and international cartel investigations and litigation.

Before joining Gibson Dunn, Scott 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. Scott 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.

Scott assists clients in antitrust and white-collar crime compliance, crisis management and government investigations across all industry sectors. He 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 Scott helped implement and that he oversaw while at the Division. In addition, Scott was instrumental in the design and implementation of similar leniency programs in dozens of jurisdictions around the world.

Scott ‘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, Scott 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. Scott 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, Scott supervised more than a hundred prosecutions involving wire fraud, mail fraud, FCPA, money laundering, commercial bribery, obstruction of justice and other federal crimes.

Scott is nationally recognized by Chambers USA as a leading attorney in the areas of Antitrust: Litigation, and Antitrust: Cartel from 2015-2025, where clients note that “[h]e should be your first call if you have any antitrust issue, especially cartel or price fixing-related,” and that he “has great contacts given his former DOJ antitrust role and he’s not scared to think outside the box.” He has also been ranked by Chambers Global as a leading attorney in Antitrust: Cartel from 2017 to 2025. The Legal 500 – United States named him “Hall of Fame” honoree for Antitrust – Cartel in 2022, 2024 and 2025. Additionally, Scott has earned recognition as a District of Columbia “Litigation Star” by Benchmark Litigation every year since 2016 and was named a 2023 “Litigation Star” in Competition/Antitrust. He has also been included in The Best Lawyers in America© in Antitrust Law every year since 2016. He is featured as one of Lawdragon’s “500 Leading Litigators in America” 2023-2026 and “500 Leading Antitrust & Competition Lawyers” for 2025 and 2026. Scott is recognized as a Competition Thought Leader in multiple guides published by Lexology Index (formerly Who’s Who Legal), consistently ranked in the “Thought Leaders Global Elite” list and included in the “Thought Leaders USA” guide. In addition, he is listed in Global Competition Review’s International Who’s Who: Competition Lawyers. In 2015, The National Law Journal named Scott 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. While with the Department of Justice, Scott 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 and his wife Anne, have three sons, Niklas, Lukas and Jakob.
