John S. (Jay) Darden is a partner in the Investigations and White Collar Defense practice at Paul Hastings, and is based in the firm’s Washington, D.C. office. 

Mr. Darden has practiced law for over 20 years, both as a defense attorney and a federal prosecutor. He has recently been named by Law360 as an “MVP” for White Collar, and has been recognized in Chambers-USA, Chambers-Global, and Legal500/Latin America, where clients have said about Mr. Darden:

  • great ability to distill a complex situation into something that the client can manage effectively;”
  • a great ability to manage cross-border cases with media exposure;”
  • great in front of boards;” and
  • a very sophisticated and strategic lawyer.”

Mr. Darden and his work have also been recognized in Global Investigations Review, The American Lawyer, Latin Lawyer 250, Law360, Just Anti-Corruption, and Who’s Who Legal: Investigations, and he has been named as a Washington D.C. “Super Lawyer” for more than ten years in a row.

Over the last several years, Mr. Darden’s practice has focused on defending companies and individuals in investigations by the U.S. Department of Justice (DOJ) and Securities and Exchange Commission (SEC) under the Foreign Corrupt Practices Act (FCPA). In addition to defending against U.S.-based investigations, Mr. Darden assists companies by coordinating U.S. investigations with parallel investigations by foreign authorities, resulting in lower costs, less publicity, and more finality for clients, as well a reduction in the risk of paying twice for the same conduct. Mr. Darden provides clients with anti-corruption compliance advice and represents companies in connection with both DOJ/SEC-appointed monitorships and self-monitorships. Mr. Darden also counsels companies on issues that often flow from large government resolutions, such as negotiations with outside auditors, related civil litigation, and interactions with multilateral development banks (MDBs).

Mr. Darden’s public, high-profile FCPA representations include ABB Ltd. (Switzerland); Braskem S.A. (Brazil); Embraer (Brazil); Alstom S.A. (France); TechnipFMC plc (U.K.); and Orthofix (U.S.). Paul Hastings has received substantial industry recognition for its work on these matters, including honors such as “Most Impressive Investigations Practice of the Year,” “White Collar Group of the Year, “Compliance Group of the Year,” and “Global Dispute of the Year/Latin America.”  Mr. Darden also has been successful in obtaining DOJ and SEC declinations for FCPA-related clients.

Mr. Darden’s non-FCPA clients are typically the targets of high-profile, Washington-based investigations. Examples include U.S. government contractors and health care providers accused of submitting false claims, a news reporter subpoenaed for the identities of his confidential sources, a congressional campaign committee who was defrauded by its former treasurer, and a political consultant accused of defrauding a gubernatorial campaign. He also routinely represents high-level executives and high-net-worth individuals under investigation by the U.S. government in accounting fraud, FCPA, health care, export controls, false statements, and other white collar matters. 

As a prosecutor, Mr. Darden served in the Justice Department as an Assistant Chief of the Criminal Division’s Fraud Section, where he worked on FCPA, bank fraud, insurance fraud, money laundering, and false statement matters. During his time at DOJ, Mr. Darden was one of only a handful of federal prosecutors to try multiple health care fraud cases to verdict in multiple districts, including Miami, Houston, and Los Angeles. In addition, he trained prosecutors and agents in health care fraud and abuse matters at the Justice Department’s National Advocacy Center. For his work as a prosecutor in healthcare fraud matters, Mr. Darden received the Attorney General’s Award for Distinguished Service.

Prior to attending law school, Mr. Darden worked on Capitol Hill for three years as an aide to former U.S. Senator Sam Nunn of Georgia.
