In the case of Richard v. Union Pacific Railroad Co., No. B322044 (Cal. Ct. App. Sept. 30, 2024), the California Court of Appeal addressed the admissibility of expert testimony in a negligence lawsuit filed under the Federal Employers’ Liability Act (FELA). The court’s decision hinged significantly on the proposed testimony of a Railroad Expert Witness.
