Judicial Review of a Migration Decision: 35 Days, and It Can Be Extended

What Judicial Review Actually Is — and Isn't

Judicial review is narrow by design. A court reviewing a migration decision is checking for legal error — jurisdictional error, a denial of natural justice, or a failure to correctly apply the law — not conducting a fresh assessment of whether the decision was the right one on the facts. This is the single most important thing to understand before pursuing this pathway: judicial review cannot succeed simply because you disagree with the outcome, or because you believe the decision-maker weighed your circumstances unfairly in a way that isn't a legal error. It succeeds only where something went wrong in how the decision was made, as a matter of law.

The Three Courts, the Same 35-Day Deadline

Three courts can hear judicial review of a migration decision, and all three carry the identical 35-day figure:

- **Federal Circuit and Family Court of Australia (Division 2)** — original jurisdiction under section 476; deadline at section 477(1): an application must be made within 35 days of the date of the migration decision.
- **Federal Court of Australia** — original jurisdiction under section 476A; deadline at section 477A(1), identically worded.
- **High Court of Australia** — constitutional original jurisdiction; deadline at section 486A(1), identically worded.

The deadline structure is the same across all three — 35 days, running from the date of the migration decision — regardless of which court ultimately hears the matter.

What 'Date of the Migration Decision' Actually Means

This is a defined, non-obvious term, and getting it wrong is an easy way to miscalculate your deadline. Section 477(3) fixes the meaning: for an ART decision made under Part 5 of the Act, it's the day the decision is taken to have been made under the Act's own deeming provisions — not necessarily the day the decision was handed down, and not necessarily the day you received it. Because this date is defined by a separate legal mechanism rather than the calendar date on your outcome letter, it's worth confirming precisely rather than assuming.

The Difference From the ART Deadline: This One Can Be Extended

The ART's 28-day (or 14-day, in detention) deadline has no extension mechanism at all — the Tribunal simply has no legal power to extend it. Judicial review is the opposite. All three sections above contain an identical extension mechanism. Under section 477(2): the court may, by order, extend the 35-day period as it considers appropriate if an application for that order has been made in writing specifying why the applicant considers it necessary in the interests of the administration of justice to make the order, and the court is satisfied that it is necessary in the interests of the administration of justice to make the order. That's a genuine, real discretion — a materially different risk profile from the ART's hard stop.

How an Extension Application Works

To seek an extension, you make a written application to the relevant court specifically explaining why an extension is necessary in the interests of the administration of justice. The court then has to be satisfied, on that application, that granting the extension meets that standard. This is a discretionary judgment for the court to make — not an automatic entitlement — and the strength of your explanation for the delay, and of the underlying case, both bear on whether the court grants it.

What Happens If You Miss 35 Days and Don't Get an Extension

Without an extension being sought and granted, the court has no jurisdiction to hear the substance of the matter. An extension application, if needed, has to be made and succeed before the underlying judicial review case can proceed at all.

Which Court, and What It's Actually Deciding

All three courts apply the same 35-day rule, but they sit within different jurisdictional structures — the Federal Circuit and Family Court's Division 2 general migration jurisdiction under section 476, the Federal Court's jurisdiction under section 476A, and the High Court's original constitutional jurisdiction. In every case, the question before the court is legal error, not the underlying merits of your visa case — the court is not reassessing your evidence or circumstances afresh.

A Migration Agent Generally Can't Take This to Court For You

This is the one point in this pathway worth stating plainly: MARA-registered migration agents generally cannot conduct litigation in these courts. Judicial review requires either self-representation or representation by an Australian legal practitioner — a lawyer — not a migration agent acting alone. A migration agent may still add real value earlier in the process — helping identify whether an arguable legal error genuinely exists, and referring you to appropriate legal counsel — but cannot appear on your behalf in court as a matter of course. Honest framing matters here more than anywhere else in this cluster.

Before You Start: Is There Actually an Arguable Legal Error?

Judicial review only succeeds where there's a genuine question of law — not a disagreement with the outcome. Whether your circumstances involve an arguable legal error is a specific, fact-dependent legal question. Migratio does not assess or predict the strength of any individual case — this article describes what the law provides for, not what will happen in yours.

Can I still go to court if my ART deadline already passed?

It depends on what you're seeking to challenge and on which decision's date starts your clock. Judicial review runs on a separate 35-day deadline from the date of the relevant migration decision, and unlike the ART deadline, it can be extended. Whether it's available in your specific circumstances is a legal question worth getting advice on directly.

Is the 35-day deadline extendable?

Yes — unlike the ART's deadline, the court can extend the 35-day period if a written application is made explaining why an extension is necessary in the interests of the administration of justice, and the court is satisfied that standard is met.

Will the court re-decide my visa application on its merits?

No. Judicial review tests for legal error — jurisdictional error, denial of natural justice, or failure to correctly apply the law. It doesn't re-run the assessment of your case on the facts, and it can't succeed just because you disagree with the outcome.

Can a migration agent represent me in the Federal Circuit and Family Court or Federal Court?

Generally no. Judicial review in these courts requires self-representation or an Australian legal practitioner, not a MARA-registered migration agent acting alone. An agent can still help identify whether an arguable legal error exists and refer you to a lawyer.

What's the difference between the three courts that hear judicial review?

The Federal Circuit and Family Court (Division 2), the Federal Court, and the High Court each hear these matters under their own jurisdictional provisions, but all three carry the identical 35-day deadline and the same extension mechanism.

What does 'date of the migration decision' mean for an ART outcome?

It's a defined term — for an ART decision, it's the day the decision is taken to have been made under the Act's own deeming provisions, which is not necessarily the day the decision was handed down or the day you received it. Confirm the precise date rather than assuming it matches your outcome letter's date.
