The Mississippi Supreme Court has vacated a $4.5 million verdict in favor of plaintiffs in a case against defendant Hyundai over a serious car accident. Hyundai Motor America v. Applewhite, No. 2008-CA-01101-SCT (Miss., 2/10/11).
Casino co- workers Dorothy Applewhite, Cecilia Cooper, and Anthony Stewart were traveling in Applewhite’s 1993 Hyundai Excel after work. It is unclear who was driving, but the two women were in the front seats, and Stewart was in the rear seat. A co-worker traveling ahead of them testified that he noticed the car weaving, drifting onto the shoulder, and finally swerving into the northbound lane, where it collided with another vehicle. The Excel separated into two pieces. All three passengers in the Excel died at the scene of the accident.
Family members of the three decedents sued Hyundai. At trial, the plaintiffs undertook to prove that the Excel was not crashworthy due to alleged defects in both its design and manufacture, including the welds in the vehicle. Plaintiffs offered the testimony of several expert witnesses, including Andrew Webb, an accident reconstructionist. Webb testified that he had used a computer program to reconstruct the accident and concluded that, had the Excel remained intact, the occupants would have experienced a change in velocity of thirty-five miles per hour. Another expert then testified that at thirty-five miles per hour, it was more likely than not that the occupants would have survived the crash.
The jury awarded the plaintiffs $4.5 million, or $1.5 million for each of three decedents, finding that the automobile at issue was defective in both its design and manufacture.
On appeal, Hyundai argued that it was entitled to a new trial because it was ambushed by changes
to Webb’s opinion. As noted, one of Webb’s main contentions was that, had the Excel remained
intact, the vehicle would have experienced a change in velocity (delta-v) of no more than thirty-five miles per hour. Hyundai deposed Webb before trial, at which time Webb gave a detailed
explanation of his calculations. Months after the deposition, Webb signed an errata sheet concerning his deposition testimony, changing four key variables that he had used to make his calculations. Most notably, Webb changed the angle of the Excel from 22 degrees to 44 degrees and increased the closing speed of the Excel from 68 miles per hour to 78 miles per hour. Despite these dramatic changes, Webb did not alter his ultimate conclusion that the car would have sustained a delta-v of only thirty-five miles per hour had it remained intact.
At trial, Webb testified about the errata sheet, claiming that he had to change several variables because he realized after he had been deposed that he had made some mistakes in his initial analysis. It is undisputed that Webb’s errata sheet was not done to correct errors made by the court reporter or to clarify his testimony. On the sheet itself, Webb listed the reason for the changes simply as “range not asked.”
Hyundai moved to strike Webb’s testimony at trial, alleging that it had never received the errata sheet during discovery and that these changes were a surprise. In response, the plaintiffs argued that the changes were not material because they did not alter Webb’s ultimate conclusion. The plaintiffs also produced a letter trying to demonstrate that they had forwarded Webb’s errata sheet to the defendant. The trial court heard extensive arguments on the issue and denied the defendant’s motion.
The Supreme Court did not agree. The discovery rules impose a duty on the parties to amend a prior response when the party knows that the response, though correct when made, is no longer
true and the circumstances are such that a failure to amend the response is in substance a
knowing concealment. The failure seasonably to supplement or amend a response is a discovery violation that may warrant sanctions, including exclusion of evidence. Whether the plaintiffs did or did not send the errata sheet was unnecessary and irrelevant to a proper analysis. Even if Hyundai did receive the errata sheet, simply giving the defendant this document did not relieve the plaintiffs of their duties under the rules. The 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 witness’s testimony. See e.g., Garcia v. Pueblo Country Club, 399 F.3d 1233, 1242 n.5 (10th Cir. 2002) (“A deposition is not a take home examination.”) If a witness changes his testimony in a manner that conflicts with prior discovery responses, the sponsoring party has a duty under the rules (Rule 26(f) in this state) seasonably and formally to amend or supplement the response — not try to sneak it through in an errata sheet. This the responsibility of the party sponsoring the witness, not the responsibility of the witness.
The plaintiffs argued that Webb’s changes were not material because they did not alter his opinion that, had the car not separated, the occupants would have experienced a delta-v of only thirty-five miles per hour. The Court did not agree. The changes in Webb’s calculations were material changes because they were essential components of the basis for his opinion. When Hyundai attempted to cross-examine Webb about his calculations, Webb referred to his errata sheet at least seven times to demonstrate that he had corrected his mistakes. It is clear from Webb’s own trial testimony that the figures on the errata sheet were important to his calculations. Moreover, when Hyundai’s experts performed crash testing, they relied on and used the figures given by Webb in his deposition in an attempt to test his opinions and refute his testimony. When Webb changed his calculations, the entire crash test using Webb’s initial calculations lost much of its relevance.
The Court found that the trial judge abused his discretion by not enforcing the rules, noting “we do
not condone trial by ambush.” Hyundai was entitled to full and complete disclosure of the plaintiffs’ expert testimony, and neither these plaintiffs nor any other party litigant may rely on a witness’s notations on a deposition errata sheet as a substitute for formal and timely supplementation.
