National Standard Insurance Co. v. Gayton
National Standard Insurance Company appealed a judgment awarding workers’ compensation benefits to Chris Gayton. The central issue was the admissibility of medical records containing diagnoses and opinions from treating physicians (Dr. A.R. Fernandez, Dr. Wainscott, and Dr. Corbin) when Gayton had not listed them as expert witnesses in discovery interrogatories. National Standard argued for exclusion based on Texas Rules of Civil Procedure 166b and 215, which require designation of expert witnesses. The court, however, distinguished between testifying experts and nontestifying medical experts whose opinions are part of authenticated medical records. It held that the discovery rules for testifying experts do not preclude the admission of such medical records. Consequently, the judgment awarding benefits to Gayton was affirmed.
