The replacement of the AAT with the ART marks a significant reform in Australia’s administrative law landscape, especially in migration matters. While the core right to seek review of a migration decision remains, the process, structure, and experience of review are changing. The scope for further appeal remains limited to judicial review, ensuring legal oversight while encouraging finality and efficiency in administrative decision-making.

What is Merits Review?
Merits review involves reconsideration of a decision by a new decision-maker. This review assesses the facts, law, and policy and determines the “correct or preferable” decision.
In the context of migration law, this includes decisions made by the Immigration Department in relation to Visa refusals or cancellations.
- Sponsorship refusals
- Protection visa outcomes
Valid Lawyers will look closely at your departmental file and assist you in presenting your case in the most effective manner in order to get the “correct or preferable” decision.
What is the Administrative
Review Tribunal?
Single national tribunal replacing the AAT.
A focus on independence, integrity, and efficiency.
Introduction of streamlined processes for review.
Improved access to justice through digital platforms, clearer procedures, and user assistance.
Scope to Appeal a Decision of the ART
Further Merits Review
In most cases, no second merits review is available. However:
- Some ART decisions may be reconsidered internally (e.g., correction of obvious errors).
Valid Lawyers will assist you to present your case in the event of an internal review before a more costly Judicial Review
Judicial Review
If you believe that the ART:
- Made a legal error,
- Breached procedural fairness, or
- Acted outside its legal powers,
You may apply for judicial review in a court, typically:
- Federal Circuit and Family Court of Australia, or
- Federal Court of Australia.
Judicial review does not reassess the facts, but examines whether the decision was made according to law.

Valid Lawyers will guide you and advise you whether this option is a viable alternative based on your case theory.
