Synopsis of Rule of Law. In cases where the causal link between negligence and injury is based on subject matter that is beyond the experience and observation of laypersons, expert testimony must be considered to determine whether the link is sufficient to attach liability.
Held. Expert testimony must be considered by the fact finder when deciding if a substantial a link exists between the negligence and the injury when the subject matter is beyond the scope of lay knowledge.
Discussion. It is not enough that negligence and injury occur at the same time, there must be a causal link between them. The possibility of an injury occurring as a result of negligence is also not enough of a link. In cases where the subject matter is beyond the experience or observation of laymen, courts must depend on medical testimony to determine whether the causal link has a substantial enough foundation to find liability. The jury must be allowed to consider the expert testimony when deciding whether to award damages for the Plaintiff’s cancer in addition to his original injury.
