The Judicial Conduct Board must turn over an anonymous complaint filed against a former Luzerne County judge to an interbranch investigative body but may keep the documents related to its investigation into that judge confidential, a sharply divided state Supreme Court has ruled.

The decision, which drew opinions from four separate justices, requires the Interbranch Commission on Juvenile Justice keep the complaint under seal, however. It also bars the members of the commission from gathering information they really seemed to want — what the Judicial Conduct Board did after it received an anonymous complaint regarding former Luzerne County Judge Michael T. Conahan in September 2006.
