A patient claimed treatment injury cover for a mental injury (conversion disorder) caused by a lumbar procedure. The District Court found that the patient did not have cover as the mental injury needed to result from a physical injury, and the breaking of the skin by the spinal needle did not amount to a physical injury because it was a necessary part, or ordinary consequence, of the treatment. On appeal, the High Court found in favour of the patient, finding that the plain words of the sections supported the view that "mental injury suffered because of physical injuries can be covered as a treatment injury even if the physical injuries were a necessary part or ordinary consequence of the treatment". The High Court referred the matter back to the Reviewer to decide the substantive question of whether the patient should have cover.
