​

          Nathaniel Z. Marmur is one of New York’s leading lawyers, with 30 years representing individuals and companies in both federal and state courts. He has been profiled in the New York Law Journal, been selected as a SuperLawyer for the past Nineteen years, has published numerous articles on matters such as the federal sentencing guidelines, attorney ethics, and federal court judges, and is quoted in the mainstream media.

​

         Over his distinguished career, including seventeen years at one of New York’s premier white collar criminal boutique firms, he has successfully defended subjects of federal or state criminal investigations and prosecutions in matters of involving charges of fraud, insider trading and other violations of the securities laws, Medicare/Medicaid and health care fraud, TARP fraud, criminal trademark counterfeiting, antitrust violations, money laundering, commercial and public bribery, customs violations, and tax evasion. As part of his civil practice, he has represented plaintiffs and defendants in numerous commercial disputes and personal injury matters.

​

          In addition, Mr. Marmur is known as one of New York’s top appellate attorneys. He has argued numerous appeals before the United States Court of Appeals for the Second Circuit, the New York Court of Appeals (the State’s highest court), and the Appellate Division. His appeals have resulted in landmark decisions and have exposed statutory flaws so significant that the New York State Legislature immediately passed laws to address the problems.

​

          Mr. Marmur has personally argued nine cases before the Court of Appeals, including People v. Kozlowski, billed as the largest grand larceny case in State history, and Taub v. Altman, which limited the geographic reach of the Manhattan District Attorney's Office in the prosecution of tax and fraud cases. He was the lead author of the amicus brief in Smith v. Tormey, in which the Court of Appeals strengthened the rights of court-appointed lawyers to recover fees. In 2023, in People v. Solomon, Mr. Marmur won a unanimous decision vacating the defendant’s plea because the charging instrument was jurisdictionally defective. And in January 2015, in 155 West 21st Street, LLC v. McMullan, Mr. Marmur won a unanimous decision reversing a sanctions decision against a Park Avenue law firm. Mr. Marmur has also co-authored several other briefs before the Court of Appeals, including one on behalf of Governor Pataki in his successful battle against the Legislature over the Executive’s budget powers (Pataki v. New York State Assembly).

​

          Mr. Marmur's appeals have had an important influence on the development of criminal law in this State. Two of his cases (Taub and People v. Kozlow) have exposed statutory flaws that prompted the legislature to amend its criminal statutes. Kozlow also resulted in a change in the official commentary to New York’s bail-pending-appeal provision that recognizes the validity of bail even if the defendant has received a probationary sentence.

​

          Mr. Marmur is also an experienced criminal and civil trial lawyer. In one high-profile case, the New York Post reported that his “grueling cross-examination made for a tough day” for Mr. Marmur’s client’s ex-wife, who had accused him of electronically spying on her. A jury found for client on all counts.

​

          Of course, many of Mr. Marmur successes cannot be highlighted here, as they are the product of zealous pre-indictment advocacy that has persuaded prosecutors not to bring charges in the first place. Mr. Marmur is unafraid to vigorously challenge the prosecutor’s evidence or theories by demonstrating that indictment would be factually or legally unsupported, unfair, or against compelling interests. Where appropriate, he has secured favorable plea agreements, and he has persuaded judges to impose lenient sentences, often significantly below those set forth in federal guidelines or probation department recommendations.

           

          Mr. Marmur's regulatory experience includes the representation of professionals, including doctors, lawyers, and accountants, in matters before the New York State Office of Professional Misconduct, the Departmental Disciplinary Committees, the New York State Department of Education, the Attorney General's Medicaid Fraud Control Unit, the SEC and the NASD, and numerous other state and municipal agencies. His civil litigation experience encompasses the representation of plaintiffs and defendants in cases involving breach of contract, business fraud, insurance coverage, RICO, defamation, conversion, the UCC, partnership disputes, and negligence.
