James Koukios is co-chair of Morrison Foerster’s Investigations + White Collar Defense Group and also serves as co-head of the FCPA + Global Anti-Corruption Practice. James represents companies and individuals in high-stakes government enforcement actions and complex internal investigations. He has handled matters across a wide range of jurisdictions including Brazil, China, Greece, India, Russia, Venezuela, and Vietnam, among others. James draws on his experience as a federal prosecutor, when he tried over 20 federal jury cases and supervised hundreds of white collar investigations, to obtain the best results for his clients. He is consistently praised for his judgment and advocacy in complex investigations and enforcement actions. Chambers USA notes that he is “super experienced with excellent judgement regarding what the government is looking for and concerned about,“ while Chambers Global describes James as, “a forceful advocate when appearing before the government.”
Before joining Morrison Foerster, James spent 10 years at the U.S. Department of Justice (DOJ), beginning as an Assistant United States Attorney in Miami and finishing as Senior Deputy Chief of the Criminal Division’s Fraud Section in Washington, D.C., where he supervised investigations, prosecutions, and resolutions in the Fraud Section’s FCPA, Health Care Fraud, and Market Integrity and Major Fraud Units. While at DOJ, James investigated and prosecuted health care fraud, procurement fraud, domestic and foreign corruption, money laundering, and export control offenses, working closely with state, federal, and foreign law enforcement officials, as well as the U.S. Securities and Exchange Commission (SEC), the U.S. Departments of Defense, State, and Commerce, and intelligence agencies.
While at DOJ, James assisted in drafting the widely acclaimed DOJ and SEC joint publication A Resource Guide to the U.S. Foreign Corrupt Practices Act, which followed a series of consultations with business and compliance leaders. He was also a lead examiner for the Phase 2 examination of Russia’s compliance with the Anti-Bribery Convention of the Organisation for Economic Co-operation and Development (OECD).
James has been recognized as: a leading lawyer in FCPA (Nationwide and Global) by Chambers USA and Chambers Global; a recommended lawyer for corporate investigations and white collar defense by Legal 500; an “Expert” and a “Thought Leader” in investigations by Who’s Who Legal; and an “Attorney Who Matters” by the Ethisphere Institute for making an impact in the area of ethics and compliance. He also received the Assistant Attorney General’s Distinguished Service Award in recognition for his work on two landmark FCPA-related trials: United States v. Esquenazi and United States v. Duperval. James also served as a lead prosecutor in United States v. AEY Inc., a defense procurement fraud and export licensing case that served as the basis for the 2016 film War Dogs.
James is a recognized thought leader on the latest legal trends and industry developments. Chambers Global notes that, “James has a keen ability to distill trends and enforcement down to their core. He is a crisp thinker and discerning with regards to the market.” He is the lead editor of our award-winning monthly newsletter, Top 10 International Anti-Corruption Developments, which succinctly summarizes important case and policy developments for busy in-house counsel, compliance professionals, and anti-corruption lawyers. James also served as an adjunct professor of trial advocacy at the Georgetown University Law Center for over 10 years and regularly guest lectures at leading law and business schools on investigations, white collar enforcement, and anti-corruption issues.
