While there are strong textual and structural bases for the independence of the judiciary in the Commonwealth Constitution, the same is not true of the State constitutions. State courts, unlike their federal counterparts, are therefore capable of exercising non-judicial functions. For example, the District Court of South Australia, through its Administrative and Disciplinary Division, conducts merits review of administrative decisions, a function which at Commonwealth level can only be exercised by Executive tribunals. Nevertheless, a degree of judicial independence is maintained at State level by convention.
