Superior Court Judges Margaret M. Hayden, Mitchel E. Ostrer and Jerome M. St. John will be elevated to the Appellate Division effective Aug. 1, Chief Justice Stuart Rabner has announced.
The Appellate Division of the Superior Court is New Jersey's intermediate appellate court. The 35 Appellate Division judges hear appeals from decisions of the trial courts, the Tax Court and state administrative agencies. The Appellate Division decides approximately 7,000 appeals and 7,500 motions each year.

A former member of the statewide Domestic Violence Working Group, Hayden served as the lead judge on domestic violence cases from 2004 to 2006. She served as lead judge for Children in Court (dependency) cases and for the Newark Model Court from 2008 to 2011.
A graduate of Georgetown University School of Foreign Service and Rutgers University School of Law-Newark, Hayden began her legal career in 1973 at the Newark firm of Ball, Hayden, Livingston & Smith. In 1985, she joined the Environmental Protection Bureau of the New York Office of the Attorney General as assistant attorney general.
In 1987, Hayden joined Rutgers University’s Environmental Law Clinic, where she worked as a senior attorney training law students in complex litigation involving environmental law.

In 1992, he returned to New Jersey and became of counsel to the law firm of Sills Cummis & Gross in Newark, concentrating in commercial litigation. He joined Gov. McGreevey’s administration in 2001, serving as his policy counselor before his appointment to the bench.
Appointed to the Superior Court in 2006 by Gov. Jon Corzine, St. John served in the criminal division in the Essex Vicinage until 2009, when he was transferred to the civil division. He returned to the criminal division last year and has remained there until his elevation to the Appellate Division.
