Judicial Review

Jurisdictional Error

Jurisdictional error is the threshold a court applies before it will set aside a migration decision. Where the decision-maker fell into jurisdictional error, the decision is invalid in law. Where no error occurred, the decision stands, however harsh or unfair it may appear.

The leading authorities

Jurisdictional error is a legal concept developed by the High Court. The doctrine emerged in Craig v South Australia (1995) 184 CLR 163, was confirmed in the migration context by Kirk v Industrial Court of NSW (2010) 239 CLR 531, and was refined materially by Hossain v Minister for Immigration and Border Protection (2018) 264 CLR 123 and MZAPC v Minister for Immigration and Border Protection (2021) 273 CLR 506.

Craig identified the categories of jurisdictional error that have come to dominate migration practice. Kirk confirmed that statutes cannot exclude judicial review for jurisdictional error from State Supreme Courts and, in subsequent application, the federal courts. Hossain and MZAPC introduced and developed the materiality requirement: an error is jurisdictional only if it could realistically have made a difference to the outcome.

Categories of jurisdictional error

The categories overlap. A given factual scenario can engage more than one at once. The categories below are the recurring grounds in migration judicial review.

Procedural fairness

Failure to put adverse information to the applicant for comment, denial of an interpreter or inadequate interpretation, undisclosed material driving credibility findings, or apprehended bias. The Migration Act's procedural codes are often exhaustive of common law procedural fairness — but only where the codes apply.

Misidentification of the issue

Asking the wrong question, applying the wrong statutory test (for example under Section 501 or a public interest criterion), or mischaracterising the case the applicant put forward. Statutory misconstruction is often the strongest pleading where the underlying evidence was favourable.

Failure to consider relevant material

Ignoring evidence that addressed a substantial element of the case the Tribunal had to decide. The failure must be material — where the failure is established but the court is not persuaded the result would have been different, materiality defeats the application.

Acting without evidence

Making findings of fact for which there was no probative evidence before the decision-maker. Distinct from the merits question of whether the available evidence was sufficient — this is the question of whether there was any evidence at all.

The materiality threshold

Following Hossain and MZAPC, an error is jurisdictional only where it was material to the decision. The applicant must establish a realistic possibility that the outcome would have been different had the error not been made. The standard is not certainty — it is realistic possibility — but it is real, and the applicant carries the onus.

Materiality is now the most contested aspect of modern migration judicial review. Many otherwise-arguable errors fail because the court is not persuaded that the error mattered to the outcome. Common materiality challenges include cases where the error related to a peripheral finding rather than a central one; where the decision-maker also relied on independent grounds that would have produced the same outcome; and where the disputed evidence, even taken at its highest, would not have changed the result.

The pleading is the case

Generic pleadings of "unreasonableness" or "failure to properly consider" are routinely struck out. Visa Plan Lawyers drafts pleadings that survive summary dismissal, with each alleged error tested for materiality before it goes into the document.

Jurisdictional error questions

What is jurisdictional error?
Jurisdictional error occurs when a decision-maker steps outside the limits of the power conferred on them — by misidentifying the issue, asking the wrong question, ignoring relevant material, denying procedural fairness, applying the wrong legal test, or acting without evidence. The concept was developed by the High Court in Craig v South Australia (1995) and is the threshold for judicial intervention in migration decisions.
What is the materiality requirement?
Following Hossain v Minister for Immigration and Border Protection (2018) and MZAPC v Minister for Immigration and Border Protection (2021), an error is jurisdictional only if it was material to the decision. The applicant must establish a realistic possibility that the outcome would have been different had the error not been made. The standard is realistic possibility, not certainty, but it is a real threshold.
What is the difference between jurisdictional and non-jurisdictional error?
A jurisdictional error invalidates the decision and grounds judicial intervention. A non-jurisdictional error is an error within the decision-maker's jurisdiction that does not invalidate the decision. The distinction is technical and turns on the nature of the error and its relationship to the decision-maker's power. Most successful judicial review pleadings depend on this distinction being clearly articulated.
What is procedural fairness?
Procedural fairness requires the decision-maker to give the affected person a fair opportunity to be heard, to disclose adverse information so it can be addressed, and to act without apprehended bias. In migration matters, procedural fairness is shaped by the procedural codes in the Migration Act, which are exhaustive in many cases. Common law procedural fairness applies where the codes do not.
Can I argue that the decision was unreasonable?
Legal unreasonableness — sometimes called Wednesbury unreasonableness or unreasonableness in the Minister for Immigration and Citizenship v Li (2013) sense — can ground jurisdictional error in narrow circumstances. The standard is high. The court does not substitute its own view of what is reasonable. The decision must be one that no reasonable decision-maker could have made on the material before them. Generic 'unreasonable' pleadings without this analytical framework are likely to fail.
What happens if jurisdictional error is found?
Where jurisdictional error is established and material, the court sets aside the decision and remits the matter to the original decision-maker (usually the Tribunal) for fresh consideration in accordance with the court's reasons. The court does not substitute its own decision on the merits. A successful judicial review provides a fresh opportunity to argue the case before the Tribunal, not a guaranteed grant or revocation.
