Expert Testimony Remains Absolutely Privileged Against Being Basis For Claims

Most states recognize an absolute privilege for statements in testimony or pleadings in a judicial proceeding. In MacGregor v. Rutberg, 478 F.3d 790 (7th Cir. Feb. 27, 2007), the plaintiff attempted to carve out an exception for expert testimony. She argued that while acting as an expert for a patient that was suing her for malpractice, defendant neurosurgeon gave testimony that defamed her. Applying Illinois law, the court refused to exempt expert testimony from the absolute testimonial privilege. The court observed, "Litigation is costly enough without judges’ making it more so by throwing open the door to defamation suits against expert witnesses."
