Margaret Marshall retires from SJC

Margaret Marshall, chief justice of the state’s highest court, officially ended her 11-year tenure as chief justice Tuesday evening, a Supreme Judicial Court spokeswoman confirmed Wednesday morning.

“She worked late last night and then quietly left her office,” spokeswoman Joan Kenney told the State House News Service. Mrs. Marshall announced plans over the summer to retire, to spend time with her ailing husband, former New York Times columnist Anthony Lewis. The couple are longtime West Tisbury seasonal residents.

Judge Marshall’s tenure included the court’s landmark 4-3 ruling, which she authored, that ultimately led to the legalization of gay marriage in Massachusetts.
