A group of 20 former judges and legal scholars have written an amicus curiae brief in the class action suit against two former Luzerne County judges and others, supporting arguments that Michael T. Conahan and Mark A. Ciavarella Jr. should not be able to invoke the doctrine of judicial immunity.

They say the doctrine cannot cover judges who have admitted to criminal conduct because of public policy concerns. The brief comes less than two weeks after plaintiffs attorneys urged U.S. District Court Judge A. Richard Caputo, in an 87-page filing, to reject the former judges’ claims of judicial immunity.
