Expert testimony is a critical element of medical negligence cases. The United States Supreme Court has charged trial judges with serving as “gatekeepers” who must screen out “speculative, unreliable expert testimony” before it even reaches a jury. But that does not mean judges enjoy unlimited discretion to decide which experts to admit. A federal appeals court in Atlanta recently chided a district judge for improperly excluding a plaintiff’s expert witness in a Georgia negligence case. The appeals court also rejected an attempt by the medical industry to dictate its own standards of expert witness reliability to the courts.
Adams v. Laboratory Corporation of America
The plaintiff in this case suffered from cervical cancer. She received several Pap smear tests, but the laboratory that analyzed the results failed to discover the cancer before it had spread to the plaintiff’s lymph nodes. The plaintiff then sued the laboratory for negligence.
