The Indiana Supreme Court recently issued an opinion in a car accident case in which the question before the Court was whether a party may use evidence of an expert witness’s professional disciplinary history to challenge the expert’s credibility. In Tunstall v. Manning, 124 N.E.3d 1193, 1195 (Ind. 2019), the plaintiff filed a lawsuit against a defendant driver that had rear-ended the plaintiff at a stop sign, causing injuries to the plaintiff. One of the plaintiff’s treating physicians diagnosed the plaintiff with a 28% whole body impairment.

Leading up to the jury trial, counsel for the defendant inquired about the plaintiff’s physician’s past professional discipline and the reasons underlying the physician’s past discipline. While the physician admitted his medical license had previously been on probation, he refused to answer questions about the reasons underlying his past discipline. When the defendant filed a motion in court to compel the plaintiff’s physician to answer questions about his past discipline, the trial court denied the motion, reasoning that the physician’s professional disciplinary history was not relevant because his medical license was in good standing. At trial, the defendant was unable to use the physician’s licensure probation and the reasons underlying the physician’s past discipline to impeach the physician’s testimony, which was the sole medical testimony offered by the plaintiff, based upon the trial court excluding any evidence of the plaintiff’s physician’s past licensure probation and the reasons for his past professional discipline.

After an Indiana jury returned a verdict in favor of the plaintiff, the defendant appealed, arguing the trial court abused its discretion by disallowing evidence of the plaintiff’s physician’s licensure probation and the reasons underlying his professional discipline. In personal injury cases in which there are competing expert opinions as to the seriousness of a person’s injuries, expert testimony can be particularly important in affecting the amount of any jury verdict in favor of the plaintiff. Once the foundation for an expert’s opinions has been established, the accuracy, consistency, and credibility of the expert’s opinions can be challenged by the parties. The question in this case was whether the plaintiff’s physician’s expert opinions could be attacked by evidence of his professional disciplinary history.
