The Supreme Court may conduct an urgent review of the decision of a substitute decision-maker appointed under an advance care directive, on the application of:

The review is limited to ensuring that the substitute decision-maker's decision is in accordance with the advance care directive and the Advance Care Directives Act 2013 (SA) [s 52(2)(a)]. The review cannot be undertaken in respect of a decision to withdraw or withhold health care if the person who gave the advance care directive is in the advanced stages of an illness without any real prospect of recovery and the effect of the health care would be merely to prolong the person's life [s 52(2)(b)].

On a review, the Supreme Court may confirm, cancel or reverse the decision of the substitute decision-maker, and make any other orders necessary in the circumstances [s 52(3)].
