Sandler was a plaintiff in an underlying medical malpractice action in which he alleged that he received substandard care at Advocate Good Samaritan Hospital. Advocate retained a standard of care witness who testified against him. Sandler, even though he won the underlying case, sued Advocate’s expert on the ground that the expert failed to diagnose his brain injury. The trial court dismissed the case on the ground that there was no doctor-patient relationship and no duty of care. The Appellate Court affirmed, but on different reasoning. The Appellate Court reasoned that a statement by an opposing expert in a report or deposition was absolutely privileged. For many years courts have recognized that a lay witness is immune from liability for his pertinent testimony at trial. The relevant caselaw, quoted in Sandler, is as follows: “As a general rule, witnesses enjoy an absolute privilege from civil suit for statements made during judicial proceedings. Ritchey v. Maksin, 71 Ill. 2d 470, 476 (1978). The purpose of the rule is to preserve the integrity of the judicial process by encouraging full and frank testimony. Layne v. Builders Plumbing Supply Co.,210 Ill. App. 3d 966, 969 (1991). ” Sandler ¶ 26.
