A nationally recognized and highly regarded trial lawyer, Matthew Menchel focuses his practice on government enforcement defense and complex civil litigation. He often serves as lead counsel on high-profile matters.

Mr. Menchel is widely renowned for his skill in the courtroom. Recognized as “an absolutely first-class trial practitioner” by Chambers USA, he is described as “truly gifted at cross-examinations and at communicating with a jury.” The Daily Business Review has twice chosen him as the "Most Effective Lawyer" in the criminal law category. The presiding judge on a highly publicized, eight-week-long Foreign Corrupt Practices Act trial commented about Mr. Menchel’s trial skills: “his cross-examination was about as textbook an example of a vigorous cross-examination as I’ve ever seen.”

Outside the courtroom, Mr. Menchel oversees the firm’s Trial Advocacy program. In that capacity, he has brought together experienced trial lawyers to exchange ideas and best practices, as well as put on live demonstrations.

Before joining Kobre & Kim, Mr. Menchel was a prosecutor at the U.S. Department of Justice (as an Assistant U.S. Attorney in the Criminal Division of the U.S. Attorney’s Office for the Southern District of Florida), where he was also chief of the Criminal Division. He also served as a prosecutor in the New York County District Attorney’s Office, during which time he trained Assistant District Attorneys in trial advocacy as the director of legal training.

Select Engagements

Government Enforcement Defense

  • Representation of DRW Investments LLC in a highly publicized case brought by the U.S. Commodity Futures Trading Commission (CFTC) over alleged market manipulation of interest rate swap futures. After a bench trial in the U.S. District Court for the Southern District of New York, the Court returned a verdict in favor of the defense and against the CFTC on all causes of action.
  • Obtained landmark acquittal on behalf of Raoul Weil, former head of UBS Wealth Management and the highest-ranking Swiss banker to stand trial in the U.S., on allegations that he conspired with wealthy Americans to hide US $20 billion in secret offshore accounts. Kobre & Kim was brought in as special litigation counsel for the trial in Florida, where the firm’s aggressive cross-examinations of government witnesses and closing arguments played a key role in crippling the government’s case.
  • Representation of 3Red Trading LLC and its owner and principal trader, Igor Oystacher, in connection with a potential enforcement action by the U.S. Commodity Futures Trading Commission (CFTC) concerning alleged "spoofing" and market manipulation.
  • Representation of Pankesh Patel in the highly publicized, eight-week-long “Foreign Corrupt Practices Act (FCPA) sting operation” in Washington DC. Mr. Menchel took the unusual and bold step of calling the government’s lead case agent on the defense’s case in chief and aggressively cross examined him to expose the many deficiencies in the implementation of the sting operation. This tactic was widely held to be the turning point in the trial and resulted in a mistrial as to the charges against Mr. Patel and, ultimately, the flaws exposed by Mr. Menchel led the government to voluntarily dismiss the charges against Mr. Patel rather than retry the case.
  • Representation of Brian Hunter, the former head of energy trading at Amaranth Advisors LLC, a fund that had US $9 billion under management, in connection with market manipulation actions by the CFTC and the Federal Energy Regulatory Commission (FERC), a pre-emptive suit against the FERC for overreaching the limits of its jurisdiction, and in the defense of several class and private civil suits. Kobre & Kim obtained complete dismissal of FERC case by a precedent-setting opinion of U.S. Court of Appeals for the DC Circuit that the FERC lacks jurisdiction over energy futures.
