The Judicial Conduct Board voted in 2006 to table an investigation into a detailed complaint filed against former Luzerne County Judge Michael T. Conahan after its chief counsel notified the board of the complaint’s existence, according to the current board chairman.

The 12-member board did so, however, without seeing the complaint or being advised as to the nature of its allegations, JCB Chairman John R. Cellucci said Wednesday. Instead, Cellucci said, the board’s chief counsel, Joseph A. Massa Jr., told board members that an anonymous letter containing allegations against Conahan had been received by the board and that “there was a criminal investigation going on.”
