Jason P. Hernandez is a Shareholder in the Litigation department and a member of the Firm’s Board of Directors. His practice focuses on complex commercial litigation, white collar criminal representations, and appellate advocacy.

Jason has obtained significant victories for both plaintiffs and defendants in civil litigation matters. For example, Plaintiffs represented by Jason obtained a $100 million class action settlement from one of the world’s largest real estate companies. Also, on behalf of a plaintiff, he settled a $30 million federal securities fraud lawsuit after defeating eight defendants’ summary judgment motions. Additionally, a defendant represented by Jason in an arbitration defeated multi-million dollar breach of contract and fraud claims.

In criminal representations, Jason has persuaded state and federal prosecutors to not bring charges against his clients; obtained a “no jail time” sentence for a client who was accused of perpetrating a multi-million dollar fraud; and has won sentencing appeals in two different federal appellate courts.

Prior to joining the Firm, Jason was an Assistant United States Attorney in the Southern District of New York. Jason’s work as prosecutor has been covered by multiple media outlets. He has appeared on camera to discuss his cases on television programs such as 60 Minutes, CNBC’s American Greed (twice), and The Con, and in the documentaries Sour Grapes and Made You Look: A True Story About Fake Art. As an AUSA, Jason investigated and prosecuted cases involving financial fraud such as the FCPA, mail/wire fraud, complex tax offenses, money laundering, commercial kickbacks/bribery, securities fraud, Ponzi schemes, embezzlement, and health care fraud. As a prosecutor, Jason successfully tried five cases to a jury and argued five appeals on behalf of the United States in the Second Circuit Court of Appeals.

Jason was also previously Associate General Counsel at HSBC Holdings in New York City, where he was in charge of conducting global internal investigations for the bank involving the Foreign Corrupt Practices Act (FCPA), antitrust law, trade sanctions, and the Bank Secrecy Act/anti-money laundering laws, among other things.

Immediately following law school, Jason was an associate in Kirkland & Ellis’ office in Washington, DC.

Jason clerked for United States District Judge Kenneth M. Karas in the Southern District of New York, and was a judicial extern for United States Circuit Judge (now United States Supreme Court Justice) Sonia Sotomayor.

Jason graduated from the University of Michigan with a B.A. in Political Science in 2000, and from Columbia Law School in 2005, where he was a Harlan Fiske Stone Scholar.
