Preparing expert witnesses for deposition is vital. To this end, working with an expert witness to ensure their expert opinions fit within the context and theme of your case and burden of proof is equally vital. Not doing so can be fatal to your case. This can lead to unprepared testimony or opinions that may appear innocuous but are in fact detrimental to your claims.
For example, in the recent opinion in Lesnik v. Duval Ford, LLC, 41 Fla.L.Weekly D281a (Fla. 1st DCA 2016), the plaintiff’s expert witness was deposed. The case involved a single vehicle accident where the plaintiff asserted claims against the dealership he purchased his used vehicle from. During deposition, the expert was asked specific questions and answered that he had no expert opinions as to those questions/issues. The Defendants filed a motion for summary judgment. In response to the motion, the plaintiff filed an affidavit of his expert. The problem, however, was that the expert rendered opinions in the affidavit that contradicted with his deposition testimony. In other words, he rendered opinions in the affidavit as to issues he previously testified that he had no expert opinions on. The trial court struck the affidavit based on the law that “a litigant when confronted with an adverse motion for summary judgment, may not contradict or disavow prior sworn testimony with contradictory sworn affidavit testimony.” Lesnik, supra, quoting Ondo v. F. Gary Gieseke, P.A., 697 So. 2d 921, 923 (Fla. 4th DCA 1997). The appellate court affirmed (explaining that reviewing trial court’s order striking the expert’s affidavit was an abuse of discretion standard of review and the trial court acted within its discretion).
