Charles Evans Hughes, Voehl v. Indemnity Insurance Company of North America…
“ Service in extra hours or on special errands has an element of distinction which the employer may recognize by agreeing that such service shall commence when the employee leaves his home on the duty assigned to him and shall continue until his return. And agreement to that effect may be either express or be shown by the course of business. In such case the hazards of the journey may properly be regarded as hazards of the service, and hence within the purview of the Compensation Act. ”
