Miss. Supreme Court: Deposition Errata Sheet No Substitute for Formal Rule 26 Expert Supplementation
On Thursday a unanimous Mississippi Supreme Court reversed a $4.5 million jury verdict and ordered a new trial in Hyundai Motor America v. Applewhite.
The decision involved a products liability case tried in the Circuit Court of Coahoma County. The plaintiffs were the beneficiaries of three persons killed in a car crash involving a 1993 Hyundai Excel. Plaintiffs alleged that the vehicle was not crashworthy due to design and manufacturing defects.
Hyundai's appeal focused on Daubert challenges of the plaintiffs' three expert witnesses. The Court ruled that the trial court did not abuse its discretion by admitting the experts' testimony. Significantly, the Court rejected Hyundai's argument that computer simulations alone are not sufficient to support expert testimony. The Court stated that: “[w]e are not prepared to say that an expert must physically build a model of his alternative design in order to to demonstrate efficacy.”
But the plaintiff got into trouble over changes to testimony that one of the experts made in his deposition errata sheet. The changes were to four variables used to make the expert's calculations. The plaintiff did not precede or follow the errata sheet with a formal supplementation of the expert's opinions pursuant to Miss. R. Civ. P. 26.
The Court stated that: “[t]he purpose of an errata sheet is to correct scrivener's errors or provide minor clarification; it is not a means of making material, substantive changes to a witnesses's testimony.” As a result, parties may not rely on a witness's deposition errata sheet as a substitute for formal and timely supplementation.
The Court ordered a new trial due to the plaintiffs' failure to supplement their discovery responses.
Justice Kitchens' wrote the Court's opinion. Ralph Chapman and others represented the plaintiffs. Lawyers from Watkins and Eager in Jackson represented Hyundai.
My Take:
This is not a surprising decision. The Supreme Court likes to see the rules of civil procedure adhered to. Lawyers have to be careful to supplement discovery responses, including expert opinions. This was not a total loss for plaintiffs, since the Court remanded the case instead of rendering.
