Peter L. Zimroth

Retired Partner

Peter Zimroth is recognized as an accomplished trial lawyer and appellate advocate, as well as a leading litigator in products liability, commercial, securities, and white collar crime matters. He has tried jury and nonjury cases and arbitrations, argued appeals at every level of state and federal court (including in the US Supreme Court), and represented clients before government and regulatory agencies, disciplinary panels, and congressional committees. He currently serves as the independent monitor appointed by the federal court to oversee the New York City Police Department's stop and frisk reforms and as the director of NYU Law School's Center on Civil Justice.

Prior to joining Arnold & Porter, Mr. Zimroth was corporation counsel of the City of New York. The corporation counsel, the city's chief legal officer, is in charge of all the city's legal business, and heads the city's law department of more than 500 lawyers. As corporation counsel, Mr. Zimroth supervised major litigations, was the prosecuting authority in juvenile cases and provided counsel on employment issues, major economic development projects, city contract and procurement policies, environmental, healthcare, law enforcement, transportation and education issues, tort and products liability, and legislation. He was the architect of the City's law providing for the public financing of city elections, a law which has become the model for local legislation around the country.

Earlier in his career, Mr. Zimroth served as an assistant US attorney for the Southern District of New York (securities fraud unit) and as the chief assistant district attorney in Manhattan, the highest non-elected position in the district attorney's office. He was a tenured professor at the New York University School of Law and a law clerk to US Supreme Court Justice Abe Fortas and to Chief Judge David Bazelon of the District of Columbia Court of Appeals. He was the editor-in-chief of the Yale Law Journal. He was appointed by the chief judge of New York State to serve as one of the three directors of the now defunct Capital Defender's Office, which had the responsibility of ensuring legal representation for indigents charged with capital offenses, and served on the Moreland Commission appointed by Governor Andrew Cuomo to report on campaign finance and related ethical issues.

Mr. Zimroth has served on many boards and committees among which are the executive committee of the New York City Bar Association, chair of its Criminal Law Committee, the ACLU's Privacy and Due Process committees, the board of the Legal Aid Society, the C.P.L Advisory Committee to the Judicial Conference and the boards of two schools for children with learning disabilities. He serves as a referee for the Appellate Division First Department in attorney discipline matters.

Mr. Zimroth has been published on a wide variety of subjects in the Yale Law Journal, The New York Times, and The New York Law Journal. He is the author of "Perversions of Justice" (Viking Press, 1974), a book about political trials.
