Johnson v. Illinois Workers’ Compensation Commission

Deputy sheriff left his assigned patrol zone to get his personal mail from a post office across county line, and while leaving post office he received a dispatch to assist another deputy sheriff. While en route there, he was in a car accident and was injured. As he driving a county sheriff's patrol car, and responding to an assignment from his dispatcher to assist another deputy sheriff, the only reasonable conclusion to be drawn from facts is that at time of injury he was acting within sphere of his employment, in obeying instructions of his employer to assist another deputy, and that his injuries arose out of and in course of his employment. (HOLDRIDGE and STEWART, concurring; McCULLOUGH and HUDSON, dissenting.)
