Prock v. Bull Shoals Landing
390 S.W.3d 78
Ark. Ct. App.2012Background
- Prock sustained a severe explosion injury while cutting barrel tops with an acetylene torch at Bull Shoals Landing; he tested positive for illegal drugs after admission to the hospital.
- Arkansas workers’ compensation presumption applies when an injury is substantially occasioned by illegal drug use; the burden shifts to the claimant to rebut by a preponderance of the evidence.
- The ALJ credited Prock’s testimony that he did not smoke marijuana on the day of the accident and found the injury not caused by impairment.
- The Commission reversed, discredited Prock’s credibility, and held that Prock failed to rebut the presumption due to inconsistencies and the timing of other witnesses’ observations.
- The appellate court reviews the Commission’s credibility determinations for substantial evidence and affirms if reasonable minds could reach the same result.
- Dissent argues lack of direct causal link between marijuana and the explosion and would reverse for benefits.
