After taking charge of a dead human body or stillbirth, the funeral director or person acting as such shall:
(a) Contact the attending physician to ascertain whether the death is from natural causes and if the death is from natural causes that the physician will certify to the cause of death; or
(b) If the physician refuses to certify to the cause of death, the death was unattended, or the circumstances suggest that the death was not due to natural causes, contact the local registrar who shall refer the case to the local health officer or coroner.
