If a person is dissatisfied with a decision of an officer under the social security law, the person may apply to the AAT for a review (an "AAT first review") of the decision.

If a person is dissatisfied with a decision of the AAT on AAT first review, the person may apply to the AAT for further review (an "AAT second review").

The rules relating to AAT review of decisions are mainly in the AAT Act, but the operation of that Act is modified in some ways by this Part for the purposes of those reviews.

The AAT Act allows a person to appeal to a court from a decision of the AAT on AAT second review.
