bankruptcy. These decisions may have been made by officials including government ministers, departments, public servants with delegated authority and statutory government bodies. The authority to review administrative decisions is limited to specific areas of government administration where an Act, regulation or other legislative instrument provides for a review by the AAT. The Tribunal has no power to enquire into government decisions generally. More than 400 federal Acts provide for review by the AAT.
