Judith McCarthy has been selected by the Southern District’s Board of Judges to serve as a magistrate judge at the Charles L. Brieant U.S. Courthouse in White Plains. McCarthy, 48, comes to the Southern District from the New York Power Authority, where she serves as executive vice president and general counsel.

McCarthy is a graduate of Barnard College and received her J.D. from the City University School of Law in 1991. She worked at the New York City Law Department from 1992 to 1998, ultimately serving as deputy assistant chief of the general litigation division.

McCarthy then served at the New York City Human Resources Administration from 1998 to 2002, rising to be first deputy general counsel before moving to the New York State Attorney General’s regional office in Westchester County from 2002 to 2011, where she was assistant attorney general-in-charge before joining the power authority in January 2011.

Chief Judge Loretta Preska said of McCarthy, “Her depth of legal experience and superb record as a litigator will make her an excellent magistrate judge, and we are lucky to have her on board.”

The Southern District also has named Frank Maas as its chief magistrate judge for a term of two years. Maas succeeds Magistrate Judge Kevin Nathaniel Fox, whose term ended on Jan. 20, 2014.
