Common questions

What is administrative law?

Administrative law is the body of law governing the activities of government decision-makers. It deals with the lawfulness of decisions, the procedures required to make them, the right to seek review, and the remedies available when decisions are flawed.

What is the difference between merits and judicial review?

Merits review looks at whether a decision was the correct or preferable one — the tribunal stands in the shoes of the original decision-maker. Judicial review looks only at the legality of the decision, not its merits. Each has different forums, grounds, and remedies.

Where are Commonwealth merits review decisions made?

Since 14 October 2024 most Commonwealth merits review is conducted by the Administrative Review Tribunal (ART), which replaced the Administrative Appeals Tribunal. The ART hears matters across migration, taxation, veterans, social security, and many other jurisdictions.

Administrative Review Tribunal Act 2024 (Cth)
What are the grounds for judicial review under the ADJR Act?

The Administrative Decisions (Judicial Review) Act lists grounds including breach of natural justice, procedures not observed, no jurisdiction, decision not authorised, improper purpose, irrelevant considerations, unreasonableness, error of law, and no evidence.

Administrative Decisions (Judicial Review) Act 1977 (Cth) s 5
What is natural justice?

Natural justice (procedural fairness) requires that a person affected by a decision has a fair hearing (the hearing rule) and that the decision-maker is impartial (the bias rule). Its content varies with the statutory context and the stakes for the individual.

Kioa v West (1985) 159 CLR 550
What is the hearing rule?

The hearing rule requires that a person be given notice of a proposed adverse decision and an opportunity to respond before the decision is made. The content depends on the statute and circumstances — sometimes an oral hearing, sometimes only a chance to comment on adverse information.

Annetts v McCann (1990) 170 CLR 596
What is the bias rule?

The bias rule requires decision-makers to be free of actual or apprehended bias. Apprehended bias is tested by whether a fair-minded lay observer might reasonably apprehend that the decision-maker might not bring an impartial mind to the decision.

Ebner v Official Trustee (2000) 205 CLR 337
What is jurisdictional error?

Jurisdictional error is an error that goes to the power of the decision-maker to act — for example, misapplying the law, denying natural justice, or making a decision without any evidence. It is the principal ground for constitutional judicial review under section 75(v) of the Constitution.

Kirk v Industrial Court of NSW (2010) 239 CLR 531
What remedies are available in judicial review?

Remedies include certiorari (quashing the decision), mandamus (compelling performance of a duty), prohibition (preventing further unauthorised action), declaration, and injunction. The court can also remit a matter for redetermination.

Judiciary Act 1903 (Cth) s 39B
What is FOI and what can I request?

FOI gives individuals a legally enforceable right of access to documents held by government agencies. Requests can be made for any document in the possession of the agency, subject to exemptions such as personal privacy, cabinet documents, and some law enforcement material.

Freedom of Information Act 1982 (Cth)
How long does an FOI request take?

Federal agencies must generally decide FOI requests within 30 days, extendable with notice. If a request involves third-party consultation, more time is allowed. Delays are common for large or sensitive requests, and complaints can be made to the OAIC.

Freedom of Information Act 1982 (Cth) s 15
Can FOI decisions be reviewed?

Yes. Applicants can seek internal review by the agency, then review by the Information Commissioner, and then review by the ART. Each level involves a fresh consideration of whether the document should be released.

Freedom of Information Act 1982 (Cth) Part VII
What are reasons and when must a decision-maker give them?

A person who is entitled to seek judicial review under the ADJR Act or ART merits review can request a written statement of reasons setting out the findings on material questions of fact, the evidence, and the reasons for the decision.

Administrative Decisions (Judicial Review) Act 1977 (Cth) s 13
What is the standing requirement for judicial review?

An applicant must have a sufficient interest to bring a judicial review — this is narrower than merits review and has been interpreted flexibly in public interest cases. Special rules apply to Attorneys-General and relators.

Australian Conservation Foundation Inc v Commonwealth (1980) 146 CLR 493
What is the difference between the ART and state tribunals?

The ART hears Commonwealth merits review matters. Each state has its own civil and administrative tribunal (NCAT, VCAT, QCAT, SACAT, WASAT, ACAT, TASCAT) for state government decisions. Their jurisdiction and procedures are set by state legislation.

How long do I have to apply for judicial review?

Under the ADJR Act, an application must be made within 28 days of the statement of reasons being provided, or within such further time as the court allows. Under the Migration Act, judicial review has a strict 35-day limit.

Administrative Decisions (Judicial Review) Act 1977 (Cth) s 11
What are the grounds for unreasonableness?

A decision is unreasonable if it is so unreasonable that no reasonable decision-maker could have made it. Following Li, Australian courts take a slightly broader view, focusing on whether there is an intelligible justification for the decision.

Minister for Immigration and Citizenship v Li (2013) 249 CLR 332
What is legitimate expectation?

A legitimate expectation could trigger procedural fairness based on past practice, representations, or ratified treaties. It has been substantially narrowed in Australia — its procedural content now depends on general principles of statutory construction rather than the doctrine itself.

Plaintiff S10/2011 v Minister for Immigration and Citizenship (2012) 246 CLR 636
Can I sue a government decision-maker personally?

Generally no. Government decision-makers acting in good faith are protected by statutory and common law immunities. Claims usually lie against the Commonwealth or State rather than the individual officer, except in narrow cases of misfeasance in public office.

Northern Territory v Mengel (1995) 185 CLR 307
How much does administrative law work cost?

Merits review in the ART is generally cheaper — filing fees are modest and cost orders are uncommon. Judicial review in the Federal Court typically costs $30,000-$250,000+ and follows the usual costs-follow-the-event rule, making it a higher-risk forum.
