Murray v. Utah Labor Commission, 308 P.3d 461

Murray, a park ranger, sustained a back injury while preparing for a boating patrol at Red Fleet State Park on July 13, 2008.
The patrol boat, tied to a dock, required Murray to bend and untie the stern cable under a combination lock, while wearing a 15‑lb service belt and a 1‑lb inflatable life jacket.
A 5–6 inch wake from another boat rocked Murray’s boat; he steadied himself by using his right foot against the side and twisting his body.
He felt back pain shortly after the incident and ultimately sought medical treatment in the ensuing days.
Murray filed a workers’ compensation claim on September 29, 2008; the ALJ denied the claim, finding the injury aggravated a preexisting, mostly asymptomatic back condition and was not the legal cause since the exertion was not unusual or extraordinary.
The Utah Labor Commission affirmed, Murray appealed to the Court of Appeals, which reviewed for abuse of discretion; the Utah Supreme Court granted certiorari to resolve the standard of review and the legal causation issue, ultimately upholding the denial.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Standard of review for agency action under UAPA	Murray contends review should be traditional mixed question, not abuse of discretion	Labor Commission argues UAPA and discretion framework supports abuse of discretion	Mixed question standard applies; abuse standard not controlling
Whether Murray showed the legal causation required given a preexisting condition	Murray argues the employment contributed to the injury beyond the preexisting condition	Commission found the activity was not legally causative beyond the preexisting condition	Court upholds lack of legal causation; denial affirmed
