BOSTON (AP) — A judge who won a $2 million libel award from the Boston Herald, then sent threatening letters to its publisher, will step down from the bench, a court said Wednesday.

Judge Ernest Murphy and the state Commission on Judicial Conduct have agreed Murphy is "permanently disabled" from performing his judicial duties, according to the order from the state Supreme Judicial Court.

Murphy has said the libel case took a severe physical and emotional toll and he suffers from post-traumatic stress.
