New York City Mayor Bill de Blasio on Friday was set to name Joni Kletter, a former labor lawyer and head of the Mayor’s Office of Appointments, to serve as commissioner and chief judge of the city’s Office of Administrative Trials and Hearings.

In her dual role, Kletter will lead an office of 300 full-time and 300 part-time employees, while also managing a bench of 12 administrative law judges assigned to hear a wide range of disciplinary disputes, as well as licensing and real estate issues referred by city agencies.
