Recently, the Louisiana Supreme Court rejected biomechanical testimony due to a lack of sufficient facts or data. In Louisiana, as elsewhere, the trial court is to serve as the “gatekeeper” in deciding the admissibility of expert testimony.
In Blair v. Coney 20-00795 (La. 4/3/20),the plaintiff sought damages for injuries caused by a rear-end collision. The defendant offered testimony from Dr. Charles E. Bain, partial owner of Biodynamics Research Corporation. Dr. Bain testified that the plaintiff was not subjected to acceleration and forces sufficient to cause lasting injuries. Dr. Bain’s testimony was based on previously conducted collision tests, photographs of the accident, and inspection of two vehicles of the same make and model.
The plaintiff moved to have Dr. Bain’s testimony excluded, claiming the testimony was irrelevant, unreliable, unduly prejudicial, and failed to satisfy the requirements of the “Daubert standard” as applied through Code of Evidence art. 702. The district court granted the plaintiff’s motion and the defendant appealed. After ordering reasons from the trial court, the appellate court reversed the trial court’s rejection of Dr. Bain. The Louisiana Supreme Court reversed.
According to the Blair Court, Dr. Bain’s testimony was properly excluded where he did not review prior medicals, inspect the vehicles involved, and made assumptions regarding the plaintiff’s body position which contradicted sworn testimony. As such, the testimony did not satisfy the reliability required for expert testimony.
The Blair Court declined to address whether Dr. Bain’s testimony satisfied any of the other requirements of Code of Evidence art. 702. The Court expressed no opinion as to Dr. Bain’s qualifications or methodology.
