Can lay testimony establish medical causation in Utah workers' compensation death claims? Hymas v. Labor Commission Explained

The Utah Court of Appeals addressed important procedural and evidentiary requirements for workers’ compensation death claims in Hymas v. Labor Commission, clarifying the standards for medical evidence and the limits of lay testimony in establishing causation.

Background and Facts

Linda Lee Hymas sought death benefits after her husband died of a heart attack while working at SOSStaffing. She claimed that physical work stress caused or contributed to his death. The medical examiner’s letter stated that work-related stress “may be a factor” but did not opine whether work activities caused or contributed to the heart attack. Mrs. Hymas did not submit records from her husband’s primary physician, and when the ALJ asked if the record was complete, her attorney confirmed it was.

Key Legal Issues

The case presented three main issues: whether the ALJ properly denied a continuance for additional medical evidence, whether lay testimony could establish medical causation, and whether a medical panel was required given the evidence presented.

Court’s Analysis and Holding

The court affirmed the Labor Commission’s decision on all grounds. First, the ALJ properly exercised discretion in denying the continuance, as Utah Administrative Code rules require parties to be prepared for hearings and lack of diligence does not constitute good cause for continuance. Second, lay testimony cannot establish medical causation – competent medical evidence is required to prove that work stress led to the resulting injury or death. Third, medical panels are only mandatory when there are conflicting medical reports, which was not present here.

Practice Implications

This decision emphasizes the critical importance of thorough preparation before workers’ compensation hearings. Practitioners must ensure all necessary medical records are obtained and submitted within the timeframes specified by Utah Administrative Code rules. The court’s holding makes clear that medical causation requires competent medical evidence and cannot be established through lay witness testimony, regardless of how compelling such testimony might be regarding workplace conditions or the decedent’s health complaints.
