Practice Areas

Mary Mulligan is co-head of Friedman Kaplan’s white collar criminal defense practice. Over the course of her more than 35-year career, she has handled matters involving virtually all aspects of white collar crime. She has been described by the New York Law Journal as a “heavy hitter” in the white collar defense bar and is renowned for her work representing individuals and corporations in sensitive and high-profile trials, federal and state investigations, complex litigation, and internal investigations.

Career

Mary previously served as an Assistant United States Attorney for the Southern District of New York, directing investigations and prosecutions of fraud, public corruption, and financial crimes.

Today, she represents clients in connection with allegations of marketing manipulation, securities fraud, money laundering, insider trading, Foreign Corrupt Practices Act violations, criminal antitrust violations, tax fraud, off-label marketing, False Claim Act violations, mail and wire fraud, public corruption, computer fraud, healthcare fraud, art forgery and theft, and other matters. She has also served as an integrity counsel to a hedge fund and as a monitor in the construction industry. She regularly conducts confidential internal investigations for companies, secondary schools, institutions of higher education, and charitable organizations. Because of the nature of Mary’s work, many of her most successful matters have not resulted in public charges and remain confidential.

Mary’s recent experience includes:

• Defended the former CFO of Archegos in a 9-week trial for market manipulation and wire fraud in the Southern District of New York. Although our client was convicted, Mary and the trial team laid the groundwork for his appeal on novel legal issues which is currently pending. In related civil actions, Mary and the firm previously obtained the dismissal of a CFTC enforcement action filed in the SDNY and continue to represent the client in a related SEC enforcement action and in a case brought by a former Archegos employee;

• Represented Chuck Blazer, the founder of organized American soccer, relating to FIFA, the international soccer organization, in connection with investigations by the FBI, DOJ, and IRS;
