The Doctrine of Double Effect and Potential Criminal Liability of Medical Practitioners in Australia

Recent parliamentary inquiries into end-of-life choices identify the need to provide legal certainty for health practitioners working in end-of-life care. A concern identified is the lack of clarity surrounding the operation, status and application of the doctrine of double effect. This discussion clarifies these concerns. Although the doctrine is judicially recognised in several overseas jurisdictions, in Australia the doctrine of precedent means that it does not form part of the common law. In most jurisdictions, the fault element for murder includes recklessness, and application of the doctrine does not avoid criminal liability being established against orthodox criminal law principles. Although the prosecution of a medical practitioner who incidentally causes death in the proper course of medical treatment is a rare event, it remains a live issue. Legislative protection of medical practitioners, as has occurred in Queensland, South Australia and Western Australia, is the means to achieve the certainty sought.
