Judicial Immunity Is NOT Absolute

When a judge knows that he lacks jurisdiction, or acts in the face of clearly valid statutes expressly depriving him of jurisdiction, judicial immunity is lost. Rankin v. Howard, (1980) 633 F.2d 844, cert den. Zeller v. Rankin, 101 S.Ct. 2020, 451 U.S. 939, 68 L.Ed 2d 326.
