No Sexton shall inter the body of any deceased person until there is produced to and filed with him the burial certificate, issued by the proper officer. If upon application for any interment the burial certificate shall be not produced to and filed with the Sexton, it shall be his duty to give immediate notice thereof to the Health Officer, or in his absence, to the Mayor. It shall thereupon be the duty of the Health Officer or Mayor to investigate the circumstances of such death.
