Three partners at large Manhattan law firms have been named as magistrate judges in the Southern District of New York.

The Board of Judges selected Stewart Aaron, a partner at Arnold & Porter Kaye Scholer who has 30 years of litigation experience, to fill the seat held by Magistrate Judge Ronald Ellis, who is stepping down after 24 years on the court (NYLJ, Jan. 19).

Aaron was a president of the New York County Lawyers Association in 2012-13 and is currently president-elect of the New York American Inn of Court. A graduate of Syracuse University College of Law, he has been a Southern District mediator since 1994.
