The doctrine of double effect will only protect a doctor
No. In most Australian states and territories a doctor, nurse, carer or family member can give medication and be protected by the doctrine of double effect. Generally though, giving the medication must be ordered or supervised by a doctor. The law in South Australia is slightly different. The medication must be given by the medical practitioner responsible for the person’s treatment, or a person supervised by that medical practitioner such as a nurse or carer.
