Marshall A. Mintz is a criminal defense lawyer in New York City who has experience with a vast variety of criminal matters, ranging from high‑profile federal trials to simple misdemeanor prosecutions in New York City Criminal Court. He has obtained favorable results for clients accused of racketeering, narcotics offenses, mail and wire frauds, access device frauds, weapons possession, assault, and many other crimes.

Mr. Mintz graduated from the University at Buffalo in 1996 and earned his law degree from Brooklyn Law School in 1999. Starting in 1999, he practiced with a noted and high-profile criminal defense lawyer in new York City for several years before opening his own practice in 2004.

 Mr. Mintz was previously a member of the Criminal Justice Act Panel for the United States Court of Appeals for the Second Circuit, providing legal representation for indigent defendants who have been convicted of federal crimes in the states of Connecticut, New York, and Vermont. He has also served on the Board of Directors of the New York State Association of Criminal Defense Lawyers, and was co-chair of its Amicus Committee, which files “friend of the Court” briefs in appellate cases which raise important issues in criminal law.

Mr. Mintz is admitted to practice in the courts of the State of New York; the United States District Courts for the Eastern and Southern Districts of New York; the United States Courts of Appeals for the First, Second, Third, and Fourth Circuits; and the Supreme Court of the United States. In addition, Mr. Mintz has represented multiple clients charged with federal crimes in the District of New Jersey.

Mr. Mintz has:

  • Obtained a reversal of a defendant’s convictions for murder and robbery due to the prejudicial impact of being tried together with a co-defendant;
  • Authored a brief on behalf of the New York State and National Associations of Criminal Defense Lawyers in a case which led the Second Circuit Court of Appeals to declare New York State’s Persistent Felony Offender Statute unconstitutional;
  • Successfully argued that a federal district court exceeded its authority in setting the terms of a restitution order in a bank robbery case;
  • Convinced a state prosecutor to dismiss the case against a defendant charged with felony assault;
  • Obtained a no-jail sentence for a client convicted of conspiring to commit multiple federal identity-theft and fraud offenses;
  • Convinced a federal judge to sentence a defendant to probation instead of the 24 to 30 months’ imprisonment called for by the United States Sentencing Guidelines.
