White Collar Defense and Investigations

Overview

The White Collar Defense and Investigations Practice Group defends businesses, senior executives, public officials and other individuals in a wide range of investigations and prosecutions. The group is composed of more than 250 lawyers practicing across our U.S. and international offices and draws on the expertise of more than 75 of its members with extensive government experience.

Global Investigations Review ranked Gibson Dunn No. 1 in its 2021 GIR 30, its annual “ranking of the world’s best investigations practices,” for the fourth consecutive year. Law360 named Gibson Dunn among its 2021 White Collar Groups of the Year, and Who’s Who Legal named the firm its Investigations Firm of the Year in 2020, for the second year in a row. Additionally, Benchmark Litigation Asia-Pacific 2022 ranked the firm in its China and Hong Kong White Collar Crime – International Firms categories, and Benchmark Litigation US 2022 recognized the firm in Tier 1 nationally for White Collar Crime. Chambers USA 2022 also ranked Gibson Dunn among “The Elite” (Tier 1) nationwide for Corporate Crime & Investigations, and Chambers and Partners named Gibson Dunn the winner of its Chambers USA Excellence Award in 2018 for Corporate Crime & Government Investigations.

The American Lawyer named Gibson Dunn a Finalist in its 2021 Litigation Department of the Year competition, noting that “when news breaks and the pressure rises, clients call Gibson Dunn’s litigators to regain control.” This award follows our unprecedented four wins in this biennial competition. Gibson Dunn also was named a 2020 finalist for the White Collar/Regulatory Department of the Year, and in 2016 was the winner.

Many cases involve simultaneous criminal, civil and regulatory actions arising out of the same events. To handle them, Gibson Dunn’s White Collar group draws on the full range of our skills and resources, collaborating with lawyers in other practice groups, allowing us to work with clients in almost every business sector in a wide array of substantive areas that includes:

The White Collar Defense and Investigations group includes numerous former U.S. federal and state prosecutors and officials, many of whom served at high levels within the U.S. Department of Justice, the Securities and Exchange Commission and other key investigative and prosecutorial arms of the government. Our lawyers use firsthand knowledge of how government agencies conduct investigations and prosecutions to assist our clients in navigating those processes successfully.

Our White Collar group teams with Gibson Dunn’s Crisis Management Practice to provide coordinated and efficient advice. The right response to a crisis requires a cohesive team equipped to immediately respond in an organized and strategic manner on multiple fronts, before issues become framed and fixed in the public mind. This requires interacting immediately and simultaneously with federal and local prosecutors, regulatory agencies, concerned investors and directors, the private plaintiffs’ bar, congressional investigators and the media.

Gibson Dunn’s lawyers always prepare for “x factors” that inevitably arise in such high-stakes and high-profile matters. We give legal and strategic advice for responding to crises both inside and outside the courtroom, and we have substantial experience operating in the public relations arena — a skill that has become essential to resolving the most serious and fast-moving white-collar legal challenges.
