The Illinois Supreme Court announced Monday the assignment of Cook County Circuit Court Judge Mary Anne Mason to the Illinois Appellate Court for the First Judicial District to fill the vacancy created by the upcoming retirement of Appellate Justice David P. Sterba on July 1, 2013.

Judge Mason, who served as an assistant U.S. attorney and worked in private practice, will continue her legal career in the very same place where she launched it: in the Appellate Court.

"To serve on the same Court where I started as a law clerk 36 years ago with Justice Daniel J. McNamara, Jr., is an honor beyond belief," Judge Mason said. "I am so grateful to the Supreme Court for this opportunity."

Judge Mason's assignment to the Appellate Court is effective July 8, 2013 and will continue until further order of the Court.

After serving as an Assistant U.S. Attorney for the Northern District of Illinois for five years and working in private practice for 15 years with the Chicago law firm of Kevin M. Forde, Ltd., Judge Mason was appointed to the Circuit Court in September 2000. She was subsequently elected to that position in November 2002 and was retained in 2008.

After a three month assignment to the traffic division, Judge Mason was assigned to the Juvenile Justice Division, where she presided over juvenile delinquency matters. In 2004, she was assigned to the Chancery Division where she hears matters including, among others, requests for injunctions, corporate disputes, review of final administrative decisions and trust and contract construction.

Judge Mason previously served as chair of the Supreme Court Committee on Discovery Procedures. She currently serves as chair of the Chancery Division Mediation Rule Committee.

Judge Mason has served as a board member of the Chicago Bar Foundation since 2012 and also serves as co-chair of its Pro Se Advisory Committee. She has been a member of the Chicago Bar Association, the Women's Bar Association of Illinois, the Illinois Judges Association and the American Academy of Appellate Lawyers.

Judge Mason received her B.A. in 1974 from Boston College, graduating magna cum laude. She received her juris doctor degree from Loyola University School of Law in 1977. She is married to the Hon. Michael T. Mason, who serves as a magistrate judge for the U.S. District Court, Northern District of Illinois.
