Leslie A. Maria practices in the Firm’s Complex Litigation, Toxic Torts & Products Liability, Investigations, and White Collar Defense groups.  She has broad and in-depth litigation and trial experience providing trial teams with support for the admission of evidence at trial, dispositive and discovery motions, and the preparation of fact witnesses and experts to testify in depositions and at jury and bench trials.  She conducts fact investigations and witness interviews in connection with written discovery and deposition and trial preparation. 

Ms. Maria previously was a partner in a major national law firm, practicing in its White Collar Crime and Corporate Compliance groups.  She also was an attorney at several major international law firms, where she handled internal investigations, transactional due diligence, and compliance programs related to the Foreign Corrupt Practices Act (FCPA) and the U.S. Department of Treasury Office of Foreign Assets Control (OFAC) regulations.  She worked on international investigations and advised clients concerning countries with which the United States restricts business and financial transactions, as well as on U.S. Securities and Exchange Commission and U.S. Department of Justice fraud matters.

Ms. Maria participated in a multi-year global corruption investigation of a private international engineering company headquartered in the U.S., which involved potentially corrupt payments to foreign tax officials and led to a worldwide review of all FCPA compliance issues at the company and an investigative report to the board of directors.  This ultimately led to a voluntary disclosure to the U.K. Serious Fraud Office that resulted in no prosecution in the U.K. and no referral to the U.S. DOJ.  Ms. Maria also developed a company-wide OFAC compliance program for a global Fortune 500 company after conducting an internal investigation into the company’s potential dealings with OFAC-sanctioned countries.

Ms. Maria successfully represented the lead cooperating witness in a major FCPA trial involving an alleged conspiracy to pay bribes to government officials in Azerbaijan in connection with an oil deal.  She also represented the board of directors of the largest gold and jewelry manufacturer in the Middle East in connection with an investigation into alleged self-dealing by founding board members.

In addition to her anti-corruption investigations and compliance work, Ms. Maria has represented individuals in civil and criminal investigations by the DOJ and SEC.  She represented Dallas Mavericks owner Mark Cuban in a SEC civil investigation and trial on insider trading charges that resulted in his being exonerated on all charges.  She also defended an international business process outsourcing firm in a SEC investigation and class action involving accounting and disclosure issues for stock option grants and expensing, which resulted in no enforcement action against the company and a settlement with the class plaintiffs.

Ms. Maria was an Articles Editor of the Georgetown Law Journal and a recipient of the CALI award in antitrust law.
