What changed when the AAT became the ART

Why the tribunal was replaced at all

The Administrative Appeals Tribunal ceased operating on 14 October 2024 and was replaced by the Administrative Review Tribunal. This was not a rebrand. The AAT had accumulated a reputation problem around appointments and a workload problem around migration cases, and the replacement was designed to address both.

For anyone with a review on foot at the changeover, matters transferred across. If you have a decision letter that refers to the AAT, it is not out of date in the sense that matters — your review rights did not evaporate. But the body deciding it, and some of the procedure around it, is different.

The Immigration Assessment Authority is gone

This is the change that matters most and got discussed least. The Immigration Assessment Authority handled “fast track” review of certain protection decisions, and it did so largely on the papers — usually without a hearing and with tight limits on new information.

The IAA was abolished alongside the AAT. Affected protection matters moved into the tribunal’s general review process, which is a materially different proposition: a hearing, the ability to be heard, and a decision-maker who reconsiders the case rather than auditing the paperwork.

If your protection matter was in the fast track system, the process it now sits in is not the process you were originally told about. That is worth checking rather than assuming.

“Afresh” still means afresh

The most useful thing about tribunal review has not changed. The tribunal stands in the shoes of the original decision-maker and decides the case again on the material before it. It is not looking for an error in the first decision. It is making the decision.

The practical consequence is the one people consistently underuse: evidence that did not exist, was not obtained, or was not properly explained the first time can be put before the tribunal. A refusal built on a gap in the evidence is often a refusal that can be answered.

• Documents that arrived after the original decision can generally be provided.
• Explanations that were never asked for can be put on the record.
• A submission connecting your facts to the actual legal criteria can be filed — something very few self-represented applicants do.

The deadlines did not get more forgiving

None of this changes the clock. Review periods are set by legislation, they run from the date you are taken to have received the decision rather than the date you opened the envelope, and they generally cannot be extended.

Most onshore refusals carry a review window of around 21 days. Cancellation decisions made while a person is in immigration detention can carry windows as short as 7 days. Because the period and the starting point both depend on the decision and your circumstances, the only safe assumption is that your clock has already started.

What to actually do with this

If you hold a decision you want reviewed, three things are worth doing this week rather than next month: find the decision record and read the date on it, work out which review path the decision carries, and get the application filed within time even if the evidence is still being assembled.

Filing in time preserves the right. Evidence can follow. The reverse is not true — no amount of good evidence recovers a review right that lapsed.
