Earlier this month, the Seventh Circuit Court of Appeals issued a written opinion in a product liability case discussing whether the lower court properly prevented the plaintiff’s expert from testifying. While the case did not arise in Indiana, it raises important issues for Indiana personal injury victims regarding the use and selection of expert witnesses. Additionally, the case provides some guidance for Indiana litigants, in that Indiana is in the Seventh Circuit.
According to the court’s opinion, the plaintiff was seriously injured at work while getting off a “car crushing” machine. Evidently, he slipped on a puddle of hydraulic fluid that had leaked from the machine. The plaintiff could not pursue a personal injury case against his employer due to the availability of workers’ compensation benefits. However, the plaintiff filed a claim against the manufacturer of the machine, as well as the company that leased the machine to the plaintiff’s employer. The plaintiff claimed that the machine was defectively designed.
In support of his claim, the plaintiff presented a professor in mechanical engineering as an expert witness. The expert planned to testify that the machine should have had a ladder, toe boards, and a guardrail installed to make it safe for users. The expert presented a safer proposed design in theory, but did not offer any sketches or elaborate on the concept.
