Australian Administrative Law: Government Decision-Making, Administrative Legality, and Accountability

Australian Administrative Law: Government Decision-Making, Administrative Legality, and Accountability

Introduction

Administrative law is the branch of Australian public law that regulates the exercise of governmental and administrative power. It establishes the legal principles governing how public authorities make decisions, the limits within which they must act, the procedures they must follow, and the mechanisms through which their decisions and conduct may be reviewed.

Modern government depends on an extensive administrative system. Commonwealth, State, and Territory agencies administer legislation, issue licences, determine eligibility for public benefits, regulate businesses, collect revenue, manage immigration, enforce environmental standards, investigate alleged wrongdoing, and make decisions affecting individuals, corporations, and communities. These functions require public officials to exercise powers conferred by legislation, delegated authority, and, in some circumstances, the executive power of government.

Administrative law seeks to ensure that these powers are exercised lawfully, fairly, rationally, and for proper purposes. It protects individuals against arbitrary or unauthorised government action while allowing public administration to operate efficiently and pursue legitimate public objectives. It also supports the constitutional principle that government is subject to law.

Australian administrative law has developed through several overlapping sources. The Constitution establishes important limits on executive authority and provides judicial review jurisdiction in specified circumstances. Acts of Parliament confer powers on ministers, departments, statutory authorities, and tribunals. The common law supplies principles of procedural fairness, jurisdictional error, legal reasonableness, and the proper exercise of statutory discretion. Statutory review mechanisms provide additional opportunities to challenge administrative decisions, while ombudsmen, integrity bodies, parliamentary committees, freedom of information laws, and audit institutions contribute to public accountability.

A central distinction is between judicial review and merits review. Judicial review examines whether a decision was made lawfully. It does not ordinarily permit a court to replace the administrator’s decision merely because the court would have reached a different conclusion. Merits review, by contrast, allows an authorised tribunal to reconsider the substance of a decision and, where the legislation permits, substitute the correct or preferable decision.

The Commonwealth administrative law framework has undergone a significant institutional change with the establishment of the Administrative Review Tribunal (ART), which replaced the Administrative Appeals Tribunal (AAT) on 14 October 2024. The new tribunal forms part of a broader system that also includes the Administrative Review Council’s statutory framework, judicial review under the Administrative Decisions (Judicial Review) Act 1977 (Cth), constitutional supervision by the courts, and external accountability institutions.

This article examines the foundations, principles, institutions, remedies, and accountability mechanisms of Australian administrative law. It focuses on the Commonwealth framework while explaining the role of State and Territory systems and the constitutional principles that apply across Australian public administration.

Key Takeaways

• Administrative law regulates public power. It governs the legality, fairness, and accountability of decisions made by government departments, ministers, statutory authorities, and other public bodies.
• The principle of legality is fundamental. Public authorities must act within the powers conferred on them by law and comply with applicable statutory and common law requirements.
• Judicial review and merits review are different. Courts examine legality; merits review bodies reconsider the substance of decisions where legislation gives them that authority.
• The Administrative Review Tribunal replaced the AAT on 14 October 2024. The ART provides independent merits review of specified Commonwealth administrative decisions.
• The Constitution protects judicial supervision of executive power. Section 75(v) gives the High Court original jurisdiction in matters seeking specified remedies against officers of the Commonwealth.
• The ADJR Act provides a statutory route to judicial review. It identifies grounds on which certain administrative decisions and conduct may be challenged in the Federal Court and Federal Circuit and Family Court.
• Procedural fairness is a central common law principle. Depending on the circumstances, decision-makers may need to provide notice of adverse material and a meaningful opportunity to respond.
• Administrative decisions must remain within statutory limits. Errors of law, improper purposes, failure to consider mandatory matters, unlawful delegation, and jurisdictional error may invalidate a decision.
• Reasonableness is a legal requirement. Administrative decisions must not be legally unreasonable, although courts do not substitute their own policy preferences for those of authorised decision-makers.
• Reasons and transparency support accountability. Statutes may require reasons, while freedom of information laws provide access to government-held documents subject to exemptions.
• Ombudsmen and integrity bodies perform complementary functions. They investigate maladministration, misconduct, systemic failures, and other matters within their statutory jurisdictions.
• Administrative law operates at every level of government. Commonwealth, State, and Territory systems have their own legislation and review institutions, although constitutional and common law principles provide important connections.

1. The Nature and Purpose of Australian Administrative Law

Administrative law is concerned with the legal relationship between public authorities and the individuals, organisations, and communities affected by their decisions. It regulates the exercise of public power and provides mechanisms through which unlawful, unfair, unreasonable, or otherwise defective administrative action may be challenged.

The term administrative action covers a wide range of governmental activities. It may include a minister’s decision to cancel a visa, a department’s refusal to grant a benefit, a regulator’s decision to impose a civil penalty, a local authority’s refusal of a development application, or a statutory commission’s decision to suspend a professional licence.

These decisions differ in subject matter and legal consequences, but they share a common feature: the decision-maker is exercising a power that must have a lawful source and must be exercised within the limits imposed by that source.

Administrative law performs several related functions.

First, it protects the principle of legality. Public officials cannot simply act because they consider an action desirable or administratively convenient. They must identify and comply with the legal authority for the action.

Secondly, it protects individuals against unfair administrative procedures. A decision affecting a person’s rights, interests, or legitimate expectations may need to be made through a fair process, including an opportunity to respond to adverse information where procedural fairness requires it.

Thirdly, administrative law promotes rational and accountable decision-making. A decision-maker must address the statutory question, consider legally relevant matters, avoid irrelevant considerations, and exercise discretion for the purpose for which it was conferred.

Fourthly, it provides remedies. Depending on the nature of the decision and the review mechanism, an affected person may obtain a reconsideration, a substituted decision, a declaration, an injunction, or an order setting aside an unlawful decision.

Finally, administrative law supports institutional accountability. Parliamentary scrutiny, public reporting, audit, ombudsman investigations, integrity commissions, and access-to-information laws help ensure that government administration remains subject to public and legal oversight.

The Commonwealth Attorney-General’s Department describes the federal administrative law system as a combination of merits review, investigations, internal agency accountability, and judicial review. These mechanisms are complementary rather than interchangeable. Attorney-General’s Department

2. Sources of Administrative Law in Australia

Australian administrative law derives from constitutional provisions, legislation, common law, and the institutional practices of government.

2.1. The Australian Constitution

The Constitution does not contain a single comprehensive chapter entitled administrative law. Nevertheless, it establishes important structural and jurisdictional principles that constrain administrative power.

Section 61 vests the executive power of the Commonwealth in the Crown and provides that it is exercisable by the Governor-General as the Queen’s representative. In contemporary constitutional practice, executive government operates through ministers, departments, statutory authorities, and public officials.

Section 75(v) gives the High Court original jurisdiction in matters in which a writ of mandamus or prohibition or an injunction is sought against an officer of the Commonwealth. This provision has a central role in protecting judicial supervision of Commonwealth executive action.

Section 76 allows the Commonwealth Parliament to confer additional original jurisdiction on the High Court in specified categories of matters, including matters arising under Commonwealth laws. Section 77 permits Parliament to define the jurisdiction of federal courts and to invest State courts with federal jurisdiction.

These provisions provide the constitutional foundations for judicial review of administrative action, particularly where an official acts beyond the authority conferred by law.

2.2. Commonwealth legislation

The Commonwealth has enacted several statutes that structure administrative decision-making and review. Important examples include:

• Administrative Decisions (Judicial Review) Act 1977 (Cth);
• Administrative Review Tribunal Act 2024 (Cth);
• Judiciary Act 1903 (Cth);
• Legislation Act 2003 (Cth);
• Freedom of Information Act 1982 (Cth);
• Ombudsman Act 1976 (Cth);
• Privacy Act 1988 (Cth);
• Public Governance, Performance and Accountability Act 2013 (Cth);
• Public Service Act 1999 (Cth);
• National Anti-Corruption Commission Act 2022 (Cth).

In addition, the legislation establishing individual departments, regulators, commissions, and statutory authorities commonly defines their powers, functions, decision-making procedures, and review arrangements.

2.3. Common law principles

The common law provides important controls on administrative power. These include:

• procedural fairness;
• the rule against bias;
• the obligation to consider mandatory relevant matters;
• the prohibition on improper purposes;
• limits on unlawful delegation;
• legal reasonableness;
• the requirement to act within jurisdiction;
• principles governing the interpretation and exercise of statutory discretions.

These principles may operate alongside statutory procedures. Legislation can modify or exclude some common law requirements, but it must do so through sufficiently clear language and remains subject to constitutional limitations.

2.4. State and Territory administrative law

Each State and Territory has its own administrative law framework. These systems include statutory review procedures, judicial review by superior courts, ombudsman institutions, information-access laws, integrity bodies, and administrative tribunals.

The terminology and institutional arrangements differ. New South Wales, for example, has the Administrative Decisions Review Act 1997 (NSW) and the NSW Civil and Administrative Tribunal (NCAT). Victoria has the Victorian Civil and Administrative Tribunal (VCAT), established under the Victorian Civil and Administrative Tribunal Act 1998 (Vic). Other jurisdictions have their own tribunals and statutory review mechanisms.

The Commonwealth ART does not replace State and Territory tribunals. Its jurisdiction concerns decisions made under Commonwealth legislation and other laws that specifically confer review authority on it.

3. The Principle of Legality and the Limits of Administrative Power

The principle of legality is the foundation of administrative law. It requires every public authority to identify the legal source of its power and to exercise that power within the boundaries established by law.

An administrative official may have considerable discretion, but discretion is not equivalent to unrestricted authority. A decision-maker must act within the statute or other legal instrument that confers the relevant power.

3.1. Statutory authority

Many administrative powers are conferred directly by legislation. A statute may authorise a minister to grant or cancel a licence, a department to determine eligibility for a benefit, or a regulator to issue directions to a business.

The enabling legislation determines:

• who may exercise the power;
• the circumstances in which it may be exercised;
• the purpose for which it may be used;
• the procedures that must be followed;
• the factors that must or may be considered;
• the limits and conditions attached to the power;
• whether and how the decision may be reviewed.

A decision that exceeds these limits may be invalid.

3.2. Executive and prerogative powers

Not every governmental action is based on a specific statutory provision. The Commonwealth executive also exercises constitutional and non-statutory powers, including certain prerogative powers and capacities associated with government.

However, the existence of executive power does not mean that every action taken by the government is beyond judicial supervision. The legal source, character, and limits of the power remain relevant. Statutory requirements, constitutional constraints, and applicable common law principles may regulate its exercise.

The Federal Court’s administrative law guidance recognises that federal administrative law concerns both statutory and non-statutory executive powers. fedcourt.gov.au

3.3. Public officials cannot create their own jurisdiction

A decision-maker cannot enlarge their authority simply by adopting an interpretation that gives them greater power. The meaning of the enabling legislation is a question of law for the courts.

If a statute authorises a regulator to impose a particular penalty only when specified conditions exist, the regulator cannot lawfully impose it when those conditions are absent. Similarly, a department cannot refuse an application by applying a policy that contradicts the governing statute.

This principle is central to judicial review: the question is not simply whether the decision appears reasonable as a matter of administration, but whether the official was legally authorised to make it.

4. Administrative Decision-Making: Structure, Procedure, and Discretion

Administrative decisions are made through a variety of institutional arrangements. Some are made by ministers personally, others by departmental officers acting under delegation, and others by independent statutory authorities or specialised regulators.

The legal character of a decision depends on the relevant legislation and the capacity in which the decision-maker acts.

4.1. Identifying the decision-maker

The first step in understanding an administrative decision is to identify the person or institution legally responsible for making it.

A minister may be the statutory decision-maker even where departmental officers conduct the investigation and prepare recommendations. In other circumstances, the legislation may confer the decision-making power directly on a delegate, a commission, a board, or an authorised officer.

The distinction matters because a person who provides advice or gathers evidence does not necessarily possess authority to make the final decision.

4.2. Delegation

Legislation frequently permits ministers, department heads, and statutory authorities to delegate functions to officials. Delegation allows large administrative systems to operate efficiently.

However, a delegation must be legally authorised and must comply with any conditions imposed by the statute. A person exercising a delegated power must act within the scope of the delegation and must not treat a recommendation from another person as a binding decision unless the law permits that arrangement.

The maxim delegatus non potest delegare expresses the general principle that a person entrusted with delegated authority cannot ordinarily subdelegate it without legal authority. The actual position depends on the enabling statute, which may expressly permit further delegation or establish other arrangements.

4.3. Discretion and policy

Many administrative statutes confer discretion rather than prescribe a single outcome. A decision-maker may be authorised to choose between several lawful options after considering relevant facts, statutory purposes, and policy considerations.

Government policies can promote consistency and predictability. They may guide officials in exercising discretion, but they cannot replace the statutory task. A decision-maker must remain willing to consider the individual circumstances of a case and must not apply policy as if it were an inflexible legal rule.

The High Court’s approach to administrative discretion emphasises that statutory decision-makers must exercise their own judgment within the limits of the legislation. A policy may inform that judgment, but it cannot unlawfully dictate the outcome.

4.4. Relevant and irrelevant considerations

A decision-maker must consider matters that the statute expressly or impliedly requires them to consider. The decision-maker must also avoid treating irrelevant matters as determinative.

In Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24, the High Court explained the principles governing relevant considerations. Whether a matter is legally relevant depends primarily on the proper construction of the statute conferring the power.

The decision-maker is not required to consider every fact that could conceivably be relevant in a broad practical sense. The legal obligation concerns those considerations that the legislation requires, expressly or by implication, to be taken into account.

Conversely, an official cannot allow a consideration unrelated to the statutory purpose to determine the outcome.

This distinction is particularly important in decisions involving public benefits, environmental approvals, immigration, licensing, and regulatory enforcement.

5. Procedural Fairness and Natural Justice

Procedural fairness, traditionally associated with the principles of natural justice, is one of the most important common law protections in administrative decision-making.

It concerns the fairness of the procedure through which a decision is made, rather than whether the final outcome is substantively correct.

The content of procedural fairness depends on the statute, the nature of the power, the interests affected, and the circumstances of the particular case.

5.1. The hearing rule

The hearing rule generally requires a person affected by an administrative decision to receive a fair opportunity to respond to adverse material or allegations that may be relevant to the decision.

The opportunity must be meaningful. It may require disclosure of the substance of adverse information, sufficient time to respond, and an appropriate means of presenting submissions or evidence.

The precise requirements vary. A formal oral hearing is not automatically necessary. In some cases, written submissions may provide a fair opportunity to respond. In others, the nature of the issues or the consequences of the decision may require a more extensive procedure.

5.2. The rule against bias

The second major principle of natural justice is that a decision must be made by an impartial decision-maker.

A decision-maker must not have an actual conflict of interest or a form of apparent bias that would lead a fair-minded observer to reasonably apprehend that the decision-maker might not bring an impartial mind to the matter.

The common law test for apprehended bias was explained by the High Court in Ebner v Official Trustee in Bankruptcy (2000) 205 CLR 337. The inquiry concerns the connection between the identified interest or circumstance and the feared departure from impartial decision-making.

Bias may arise from financial interests, personal relationships, prejudgment, hostility, or other circumstances. Not every prior involvement or expressed view establishes bias. The legal assessment depends on the particular facts.

5.3. The development of procedural fairness

In Kioa v West (1985) 159 CLR 550, the High Court confirmed the importance of procedural fairness in administrative decisions affecting individual interests. The case concerned immigration action and established principles that continue to influence administrative law.

The Court recognised that the hearing rule may apply where a decision affects a person’s interests, unless legislation clearly excludes or modifies the requirement.

Procedural fairness is not a rigid checklist. The content of the obligation must be adapted to the statutory context and the nature of the decision.

5.4. Materiality and denial of fairness

A denial of procedural fairness may amount to jurisdictional error, but modern High Court authority also requires attention to materiality.

In Nathanson v Minister for Home Affairs [2022] HCA 26, the High Court considered the materiality of a denial of procedural fairness in a migration decision. The case addressed whether the applicant had been deprived of a realistic possibility of a different outcome because they had not been given an opportunity to respond to relevant adverse matters.

In LPDT v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs [2024] HCA 12, the High Court again considered the relationship between legal error, materiality, and jurisdictional error.

The precise materiality inquiry depends on the nature of the statutory decision and the error alleged. It should not be assumed that every procedural defect automatically invalidates a decision, nor that a court must reconstruct the entire administrative process as if the error had not occurred. High Court of Australia+1

6. Reasons for Administrative Decisions

Reasons are important because they allow affected persons to understand how a decision was reached, identify possible errors, and decide whether to seek internal review, merits review, or judicial review.

However, Australian administrative law does not impose one universal common law duty requiring every public official to provide written reasons for every administrative decision.

The duty may arise from legislation, procedural requirements, tribunal rules, or the circumstances of the particular decision.

6.1. Statutory rights to reasons

Section 13 of the Administrative Decisions (Judicial Review) Act 1977 (Cth) provides a mechanism through which a person entitled to apply for judicial review of a decision under the Act may request a statement of reasons, subject to the statutory conditions and exceptions.

Other Commonwealth statutes may impose their own obligations to give reasons. The ART Act also establishes procedural and decision-making requirements relevant to the tribunal’s reasons and review functions.

6.2. Adequacy of reasons

Where reasons are required, they should explain the material findings, the evidence or other material on which those findings are based, and the reasoning process leading to the decision.

A statement that merely repeats the statutory language may be insufficient where it does not reveal how the decision-maker addressed the actual issues.

The adequacy of reasons is assessed in context. The required level of detail may depend on the nature of the decision, the statutory framework, and the significance of the issues.

6.3. Reasons and judicial review

Reasons may assist a court in identifying whether the decision-maker applied the correct legal test, considered mandatory matters, addressed the relevant evidence, and exercised discretion within the law.

However, inadequate reasons do not necessarily prove that the underlying decision is invalid. The legal consequence depends on whether there was a statutory duty to give reasons, whether that duty was breached, and whether the breach is material or otherwise legally significant.

7. Judicial Review of Administrative Action

Judicial review is the process through which a court examines whether an administrative decision or action was legally authorised and lawfully undertaken.

It is one of the principal mechanisms through which the rule of law applies to executive government.

Judicial review is not an appeal on the merits. A court does not ordinarily ask whether it would have made the same decision or whether another outcome would have been preferable. Instead, it examines whether the decision-maker acted within the limits of the law.

The Federal Court explains that its role in administrative law proceedings is generally to supervise legality and fairness rather than to remake the government’s decision. fedcourt.gov.au

7.1. The Administrative Decisions (Judicial Review) Act 1977

The Administrative Decisions (Judicial Review) Act 1977 (Cth), commonly called the ADJR Act, provides a statutory framework for reviewing certain administrative decisions made under an enactment.

Section 5 allows a person aggrieved by a reviewable decision to apply for an order of review on specified grounds.

Section 6 addresses conduct engaged in for the purpose of making a decision, while section 7 deals with failures to make decisions in circumstances covered by the Act.

The Act also provides for a statement of reasons under section 13, subject to its statutory conditions and exceptions.

The ADJR Act does not cover every governmental action. Its application depends on whether the decision is of an administrative character, whether it is made under an enactment, whether it falls within the statutory definition, and whether any exclusion applies.

The Federal Register identifies the ADJR Act as in force and provides the current legislative text. Federal Register of Legislation

7.2. Judicial review under the Judiciary Act 1903

Section 39B of the Judiciary Act 1903 (Cth) confers important jurisdiction on the Federal Court.

Section 39B(1) provides jurisdiction in matters in which the Commonwealth is seeking an injunction or declaration, or in which an injunction or declaration is sought against an officer of the Commonwealth.

Section 39B(1A) extends the Federal Court’s jurisdiction to specified categories of matters, including matters arising under laws made by the Commonwealth Parliament.

This jurisdiction is important where the ADJR Act does not apply or where a claimant seeks relief through the Court’s broader statutory jurisdiction.

The precise jurisdictional basis must be identified in each proceeding. Section 39B is not a general right to challenge every governmental decision without regard to the legal requirements for standing, jurisdiction, and relief.

7.3. Constitutional judicial review under section 75(v)

Section 75(v) of the Constitution provides the High Court with original jurisdiction in matters where a writ of mandamus or prohibition or an injunction is sought against an officer of the Commonwealth.

The High Court has described this provision as protecting an entrenched minimum provision of judicial review of Commonwealth executive action.

In Plaintiff S157/2002 v Commonwealth (2003) 211 CLR 476, the High Court considered the constitutional significance of section 75(v) and the limits of legislative attempts to restrict judicial review.

The decision established that Parliament cannot remove the High Court’s constitutionally entrenched jurisdiction by using a statutory privative clause to protect decisions affected by jurisdictional error.

The constitutional protection does not mean that every administrative decision is automatically reviewable in every court or that every legal error produces a successful claim. The applicant must establish a matter within the Court’s jurisdiction and identify a legally recognised basis for relief.

7.4. State Supreme Courts and judicial supervision

State Supreme Courts possess an important supervisory role over State administrative decision-makers and tribunals.

In Kirk v Industrial Court of New South Wales (2010) 239 CLR 531, the High Court held that State legislation cannot remove the defining supervisory characteristics of State Supreme Courts, including their jurisdiction to grant relief for jurisdictional error.

This principle is significant because State courts may exercise both State and federal jurisdiction. Their supervisory role is therefore an important part of the national constitutional structure.

The NSW Judicial Commission’s administrative law materials explain the distinction between ordinary errors of law and jurisdictional errors, including the constitutional significance of Kirk. judcom.nsw.gov.au

8. Grounds of Judicial Review

The grounds of judicial review identify the legal defects that may justify court intervention. They are not simply complaints that an administrative decision was unfair in a general or subjective sense. They concern failures to comply with legal requirements governing the exercise of public power.

The ADJR Act sets out statutory grounds of review, while common law and constitutional review operate through their own principles. The terminology and precise legal tests may differ between these pathways.

8.1. Absence or excess of jurisdiction

A decision-maker must act within the jurisdiction conferred by law. If an official exercises a power that the statute does not confer, misunderstands the limits of that power, or fails to satisfy a condition essential to its exercise, the decision may be affected by jurisdictional error.

For example, a licensing authority may be empowered to suspend a licence only where specified statutory grounds are established. If it suspends the licence for a reason outside those grounds, it may have exceeded its authority.

Jurisdictional error is particularly important in constitutional judicial review because it may permit relief notwithstanding statutory provisions that seek to limit review.

8.2. Error of law

An administrative decision may be invalid where the decision-maker misunderstands or misapplies the governing law.

Examples include:

• applying the wrong statutory test;
• misconstruing a provision that defines the scope of a power;
• treating a legally irrelevant matter as determinative;
• misunderstanding the legal effect of a document or prior decision;
• failing to apply a binding legal rule;
• acting on an incorrect understanding of the decision-maker’s jurisdiction.

Not every error of law necessarily amounts to jurisdictional error. The legal consequence depends on the statutory scheme, the nature of the error, and the relevant principles governing validity.

8.3. Improper purpose

A statutory power must be exercised for the purpose for which Parliament conferred it.

A decision-maker cannot use a licensing power to punish a person for conduct unrelated to the statutory licensing scheme, or use an enforcement power to achieve a private or political objective that the legislation does not authorise.

The identification of improper purpose requires interpretation of the statute and examination of the purpose for which the power was actually exercised.

8.4. Failure to consider mandatory relevant matters

A decision-maker must consider matters that the legislation expressly or impliedly makes mandatory.

In Peko-Wallsend, the High Court explained that the identification of relevant considerations depends on statutory construction. A court must determine whether Parliament intended the matter to be taken into account in exercising the particular power.

The failure to consider a mandatory matter may constitute an error of law and, where the error affects the limits of the decision-maker’s authority, jurisdictional error.

8.5. Consideration of irrelevant matters

A decision-maker may also act unlawfully by relying on matters that have no legitimate connection with the statutory task.

The fact that a matter is politically controversial, personally inconvenient, or administratively difficult does not automatically make it irrelevant. The question is whether the legislation permits or requires the decision-maker to consider it.

For instance, a regulator deciding whether a company has complied with a statutory safety obligation cannot treat unrelated personal hostility towards the company as a proper basis for enforcement.

8.6. Unlawful delegation and dictation

An authorised decision-maker must exercise the decision-making responsibility entrusted to them.

A decision may be unlawful if the official delegates the power without authority, treats another person’s recommendation as binding when it is not, or allows an external person to dictate the result.

The principle does not prevent officials from seeking expert advice, consulting colleagues, or receiving policy guidance. It requires the legally authorised decision-maker to retain and exercise the judgment that the statute assigns to them.

8.7. Legal unreasonableness

Administrative discretion is not unlimited. A decision may be invalid if it is legally unreasonable in the relevant statutory context.

In Minister for Immigration and Citizenship v Li [2013] HCA 18, the High Court considered the legal limits on administrative discretion and explained the significance of legal unreasonableness. The case concerned a tribunal’s refusal to adjourn proceedings in circumstances where the applicant sought additional time in connection with a skills assessment.

The Court did not establish that judges may substitute their own preferred outcome whenever a decision appears harsh or unwise. Rather, the decision must be assessed against the statutory purpose, the nature of the discretion, and the circumstances in which it was exercised.

Legal unreasonableness may arise where a decision lacks an evident and intelligible justification, is disproportionate to the statutory task, or reflects a failure to engage with the matters that the law requires the decision-maker to address.

The High Court’s judgment in Li remains a leading authority on this ground. High Court of Australia

8.8. No evidence and failure to support findings

The ADJR Act includes a ground concerning decisions for which there was no evidence or other material capable of supporting the decision.

This ground does not mean that a court will reassess every factual finding. Administrative decision-makers are generally responsible for evaluating evidence and drawing factual conclusions within their statutory authority.

Judicial intervention may be available where the statute requires a factual foundation and the decision-maker makes a critical finding without any legally sufficient evidentiary basis.

8.9. Fraud and bad faith

Fraud, dishonesty, and bad faith may also invalidate administrative action.

Bad faith involves more than an incorrect decision or an error of judgment. It concerns the dishonest or improper exercise of power, including deliberate misuse of authority.

Fraud may involve fabricated evidence, deliberate deception, or other conduct that compromises the legality of the administrative process.

8.10. Failure to comply with statutory procedure

Where legislation prescribes a procedure for making a decision, the decision-maker must comply with the requirements that the law makes mandatory.

Not every procedural irregularity invalidates the resulting decision. The legal consequences depend on the statutory scheme, the significance of the requirement, and whether the failure amounts to jurisdictional error or another recognised ground of review.

9. Jurisdictional Error and the Constitutional Limits on Administrative Power

The concept of jurisdictional error is central to Australian administrative law. It identifies an error that causes a decision-maker to exceed the authority conferred by law or fail to exercise the jurisdiction entrusted to them in accordance with its legal limits.

The distinction between jurisdictional and non-jurisdictional error is important because not every mistake made by a public authority invalidates its decision.

9.1. The significance of jurisdiction

A statutory decision-maker is authorised to decide particular matters within a defined legal framework. If the decision-maker misunderstands the nature or limits of that authority in a way that constitutes jurisdictional error, the resulting decision may be invalid.

Examples may include:

• asking the wrong statutory question;
• failing to exercise the jurisdiction conferred;
• denying procedural fairness where the denial is material;
• acting for an improper purpose;
• failing to comply with an essential statutory condition;
• misconstruing a limitation on the power in a way that affects the decision-maker’s authority.

The legal character of an error must be assessed in context. Courts do not treat every factual mistake, procedural defect, or incorrect interpretation as automatically jurisdictional.

9.2. Privative clauses

A privative clause is a legislative provision intended to restrict or exclude judicial review of administrative decisions.

Parliaments may enact provisions designed to create finality or limit certain forms of review. However, such provisions must be interpreted consistently with constitutional limits.

In Plaintiff S157/2002 v Commonwealth, the High Court held that a privative clause in the Migration Act 1958 (Cth) could not protect decisions affected by jurisdictional error from the High Court’s constitutionally protected jurisdiction under section 75(v).

The case demonstrates that statutory finality provisions cannot be treated as unlimited permission for public officials to act outside their lawful authority.

9.3. Materiality

The materiality of an error is an important aspect of jurisdictional error analysis. In general terms, the question is whether the error could have made a difference to the exercise of the statutory power or the outcome.

The High Court has considered materiality in cases involving procedural fairness and statutory decision-making, including Nathanson and LPDT.

Materiality is not a simple numerical test. It requires consideration of the statutory task, the nature of the error, the information that was excluded or misunderstood, and whether there was a realistic possibility of a different decision in the absence of the error.

This approach seeks to distinguish legally consequential defects from errors that could not have affected the decision-making process in the relevant statutory sense. High Court of Australia+1

10. Remedies in Judicial Review Proceedings

Where a court finds that administrative action is unlawful, it may grant remedies appropriate to the nature of the error and the jurisdiction being exercised.

The remedies available depend on the court, the statutory or constitutional basis of the proceeding, and the relief sought.

10.1. Certiorari

Certiorari is a remedy traditionally used to quash or set aside an unlawful decision of an inferior court, tribunal, or administrative decision-maker.

In contemporary administrative law, an order setting aside a decision may be available under statutory or constitutional jurisdiction, even where the technical form of the remedy differs.

The practical consequence is that the decision is deprived of legal effect, subject to the terms of the order and the relevant law.

10.2. Prohibition

Prohibition is a remedy that restrains a decision-maker from proceeding with an unlawful exercise of jurisdiction.

It may be relevant where a tribunal or public authority is about to act beyond its legal authority.

10.3. Mandamus

Mandamus compels a public authority to perform a public duty that the law requires it to perform.

It does not ordinarily dictate the substantive outcome where the statute leaves the decision-maker with discretion. The court may require the authority to make a decision according to law without directing which lawful outcome it must choose.

10.4. Declarations

A declaration states the legal position of the parties or the legal consequences of the relevant conduct.

A court may declare that a decision was made without authority, that a statutory power was misconstrued, or that a particular legal obligation exists.

Declarations are especially useful where a definitive statement of the parties’ legal rights is required.

10.5. Injunctions

An injunction may restrain unlawful conduct or require a person or authority to take a particular action where the legal requirements for relief are met.

In administrative law, injunctions may be important where the implementation of a disputed decision could cause harm before judicial review is completed.

10.6. Remittal and reconsideration

The usual result of successful judicial review is not that the court makes the administrative decision itself. Instead, the decision may be set aside and returned to the original decision-maker for reconsideration according to law.

The authority may reach the same substantive outcome after correcting the legal defect, provided that outcome remains lawful.

The Federal Court’s guidance explains that the usual orders in successful administrative law proceedings set aside the impugned decision and remit the matter for a new decision in accordance with legal requirements. fedcourt.gov.au

10.7. Damages

Damages are not ordinarily awarded merely because a decision has been found unlawful. Judicial review is primarily concerned with legality and public law remedies.

A separate cause of action may be available where the facts establish a recognised basis for compensation, such as a statutory entitlement, negligence, misfeasance in public office, false imprisonment, or another actionable wrong.

The availability of damages must therefore be considered separately from the availability of judicial review.

11. Merits Review and the Administrative Review Tribunal

Merits review is distinct from judicial review. It allows an authorised review body to reconsider the substance of an administrative decision and determine what is the correct or preferable decision in the circumstances.

The Commonwealth’s principal general merits review institution is the Administrative Review Tribunal (ART).

11.1. The establishment of the ART

The ART commenced operation on 14 October 2024, replacing the Administrative Appeals Tribunal (AAT).

It was established by the Administrative Review Tribunal Act 2024 (Cth), together with consequential and transitional legislation. The reforms also re-established the Administrative Review Council as an independent policy advisory body.

The ART is designed to provide independent, accessible, fair, and efficient merits review of decisions made under Commonwealth laws. The Attorney-General’s Department confirms that the former AAT ceased operations and that existing unresolved matters were transferred to the new Tribunal. Attorney-General’s Department+1

11.2. The ART’s jurisdiction

The ART does not have a general power to review every decision made by the Australian Government.

Its jurisdiction must be conferred by legislation. More than 400 Commonwealth Acts and legislative instruments provide for review of particular decisions, although the specific categories and conditions vary.

The Tribunal reviews decisions in areas including:

• migration and refugee matters;
• social security and family assistance;
• National Disability Insurance Scheme matters;
• child support;
• taxation;
• veterans’ entitlements;
• Commonwealth workers’ compensation;
• citizenship and passports;
• bankruptcy;
• corporations and financial services;
• aviation and customs;
• freedom of information;
• specified security-related decisions.

The Tribunal’s official explanation emphasises that it may review only decisions for which legislation confers jurisdiction. Administrative Review Tribunal

11.3. The nature of merits review

In merits review, the Tribunal considers the matter afresh within the scope of the statutory review power. It may examine the facts, the applicable law, relevant policy, and additional material that was not before the original decision-maker.

The Tribunal may:

• affirm the original decision;
• vary the decision;
• set it aside and substitute a new decision;
• set it aside and remit the matter for reconsideration, where authorised by the legislation.

The objective is to reach the correct or preferable decision according to the applicable law and circumstances, rather than merely determine whether the original decision was legally valid.

11.4. Internal review and exhaustion of procedures

Some statutory schemes require an affected person to seek internal review before applying to the ART. Others provide direct access to the Tribunal.

The legislation governing the particular decision determines the applicable process, time limits, standing requirements, and any preliminary review obligations.

Internal review may allow the original agency to correct an error without the need for an external proceeding. However, an internal review is not the same as independent merits review by the ART.

11.5. The ART and judicial review

The ART is an administrative review body, not a court exercising the general judicial review jurisdiction of the Federal Court or High Court.

A party may have access to judicial review of an ART decision where there is an error of law or jurisdictional error, subject to the relevant statutory and constitutional framework.

The Administrative Review Tribunal Act 2024 includes provisions concerning appeals on questions of law to the Federal Court. Judicial review may also be available through constitutional or other statutory jurisdiction where the requirements are satisfied.

The existence of an ART merits review process does not remove the constitutional role of the courts in supervising legality.

11.6. The Administrative Review Council

The Administrative Review Council (ARC) was re-established under the ART Act in 2024.

Its role is to advise the Attorney-General on the administrative law system, promote best practice in government decision-making, and contribute to the improvement of administrative review mechanisms.

The Council’s function is policy-oriented and systemic. It does not replace the ART as the body that reviews individual decisions, nor does it exercise the judicial review jurisdiction of the courts. Attorney-General’s Department+1

12. Judicial Review and Merits Review Compared

The distinction between judicial review and merits review is fundamental to Australian administrative law.

Issue	Judicial review	Merits review
Main purpose	Examine legality	Reconsider the substance of the decision
Institution	Court	Tribunal or authorised review body
Central question	Was the decision made according to law?	What is the correct or preferable decision?
Scope	Legal validity and jurisdiction	Facts, law, policy and merits within statutory scope
New evidence	Depends on the nature of the proceeding and legal issues	Often may be considered
Can the decision be substituted?	Generally not	Often, if legislation authorises it
Typical outcome	Set aside, declaration, injunction, remittal	Affirm, vary, substitute, or remit
Source of authority	Constitution, statutes and supervisory jurisdiction	Specific statutory conferral of review jurisdiction

The two forms of review can complement one another. A person may first seek internal review, then apply for merits review, and in appropriate circumstances seek judicial review of a legally defective decision.

However, the availability and sequence of these mechanisms depend on the statute governing the particular administrative power. They should not be assumed to exist in every case.

13. Administrative Accountability Beyond Courts and Tribunals

Judicial and merits review are central to administrative law, but they are not the only mechanisms through which public administration is scrutinised.

Government accountability also operates through complaints, investigations, audits, integrity oversight, parliamentary scrutiny, information access, and internal administrative controls.

These mechanisms serve different purposes. Some focus on correcting individual decisions, while others examine maladministration, systemic weaknesses, financial management, misconduct, or corruption.

13.1. The Commonwealth Ombudsman

The Commonwealth Ombudsman is an independent statutory office established under the Ombudsman Act 1976 (Cth).

The Ombudsman investigates complaints about the administrative actions of Commonwealth government departments and agencies, as well as certain private organisations and service providers performing functions connected with government.

The office may investigate:

• unfair administrative treatment;
• unreasonable delay;
• failure to follow proper procedures;
• inadequate communication;
• defective complaint handling;
• administrative errors;
• inappropriate conduct by agencies;
• systemic problems affecting service delivery.

The Ombudsman may also conduct investigations on its own initiative, undertake inspections and audits, and make recommendations to improve administrative practice.

The Ombudsman does not ordinarily function as an appellate tribunal with a general power to substitute a new decision for the agency’s decision. Its role is investigative and recommendatory, although its reports can have significant practical and institutional consequences.

The Office describes its role as promoting fair and responsible agency action through complaints, investigations, audits, inspections, and recommendations. Commonwealth Ombudsman+1

13.2. The National Anti-Corruption Commission

The National Anti-Corruption Commission (NACC) was established under the National Anti-Corruption Commission Act 2022 (Cth) and commenced operation on 1 July 2023.

Its principal function is to investigate serious or systemic corrupt conduct in the Commonwealth public sector.

The Commission’s jurisdiction can extend to public officials, parliamentarians, ministerial staff, employees of Commonwealth agencies, and certain contractors and other persons connected with public administration.

Corrupt conduct may involve bribery, abuse of office, misuse of official information, dishonest interference with public functions, or conduct that adversely affects the honest or impartial exercise of public powers.

The NACC does not investigate every administrative error or workplace disagreement. Its statutory threshold focuses on serious or systemic corrupt conduct. The Commission’s current guidance explains the factors relevant to seriousness and systemic character, including significant misuse of public money, substantial personal benefit, serious harm to public confidence, and patterns of organisational failure. National Anti-Corruption Commission (NACC)+1

The NACC’s role is distinct from judicial review. A court determines legal validity and grants judicial remedies; the Commission investigates potential corruption and may refer matters for prosecution or other appropriate action.

13.3. Australian National Audit Office

The Australian National Audit Office (ANAO) supports public accountability through independent audit and reporting on Commonwealth government entities.

The Auditor-General conducts financial statement audits and performance audits. Performance audits examine whether public entities have administered programs and activities efficiently, effectively, economically, and in accordance with applicable requirements.

These audits do not ordinarily determine the legal rights of individual applicants. Instead, they identify weaknesses in administration, governance, expenditure, procurement, program design, and performance management.

The ANAO reports to Parliament and publishes its audit findings. Its work can reveal systemic failures that may require administrative reform, parliamentary scrutiny, or further investigation.

The ANAO’s published performance audit program and annual reporting demonstrate the role of independent audit in examining the operation of government programs. Australian National Audit Office (ANAO)+1

13.4. Australian Public Service Commission

The Australian Public Service Commission (APSC) has responsibilities concerning the integrity, capability, and performance of the Australian Public Service.

The Public Service Act 1999 (Cth) establishes the Australian Public Service Values and Code of Conduct, together with mechanisms for managing misconduct and promoting professional standards.

The APSC supports agencies in maintaining a professional, impartial, accountable, and merit-based public service. Its functions complement judicial review and external integrity oversight.

An internal employment or disciplinary process is not the same as a judicial review proceeding. Nevertheless, compliance with public service standards is an important part of lawful and responsible administration.

14. Freedom of Information and Government Transparency

Access to government information is an important accountability mechanism. It enables individuals, journalists, researchers, businesses, and civil society organisations to examine government records and understand how public decisions are made.

At Commonwealth level, the principal statute is the Freedom of Information Act 1982 (Cth), commonly known as the FOI Act.

14.1. The right of access

The FOI Act gives a person a statutory right to request access to documents held by Commonwealth ministers and agencies, subject to statutory exemptions and conditions.

Documents may include:

• correspondence;
• internal memoranda;
• policy papers;
• reports;
• administrative records;
• contracts and procurement documents;
• decision-making material;
• briefing notes;
• other records held by agencies.

The right is not unlimited. Certain documents or information may be exempt, including material concerning national security, Cabinet processes, law enforcement, confidential information, and other protected categories specified by the Act.

The legal question is not simply whether a document is embarrassing or politically inconvenient. The agency must apply the statutory exemption provisions and, where relevant, the conditional exemption and public interest test.

14.2. Internal review and Information Commissioner review

A person dissatisfied with an FOI decision may be entitled to seek internal review or apply for review by the Australian Information Commissioner.

The Information Commissioner may examine the decision and determine whether access should be granted, refused, varied, or otherwise dealt with under the statute.

The OAIC explains that an Information Commissioner review is a merits review process. The Commissioner may consider relevant material, including information not considered by the original decision-maker. OAIC+1

14.3. The role of the Office of the Australian Information Commissioner

The Office of the Australian Information Commissioner (OAIC) administers important aspects of Commonwealth information access and privacy law.

Its functions include:

• oversight of the FOI framework;
• review of specified FOI decisions;
• investigation of complaints under the FOI Act;
• privacy regulation and guidance;
• promotion of information governance and transparency.

The OAIC’s review jurisdiction is distinct from the Commonwealth Ombudsman’s general administrative complaint jurisdiction, although there can be overlap in the kinds of administrative conduct examined.

14.4. Proactive publication

The FOI framework also encourages agencies to make certain information available proactively, rather than requiring every person to submit a formal request.

Publication schemes, disclosure logs, and other transparency practices can reduce the need for individual applications and improve public understanding of government activity.

Freedom of information is therefore both an individual access right and a broader institutional accountability mechanism.

15. Privacy and Administrative Decision-Making

Government agencies frequently collect, store, use, and disclose personal information when administering public programs and exercising statutory powers.

The Privacy Act 1988 (Cth) establishes a Commonwealth framework for the handling of personal information by Australian Government agencies and many private sector organisations.

The Australian Privacy Principles (APPs) regulate matters such as collection, use, disclosure, data quality, security, access, and correction of personal information.

Administrative decisions may be legally or practically defective where they rely on inaccurate information, disclose protected information unlawfully, or use personal data for an unauthorised purpose.

Privacy protection is therefore closely connected with administrative legality. A department may have authority to collect information for a particular statutory purpose, but that authority does not necessarily permit unrestricted use or disclosure.

The OAIC investigates certain privacy complaints and performs regulatory and guidance functions under the Privacy Act.

Privacy review and administrative review should nevertheless be distinguished. A complaint that an agency unlawfully disclosed personal information may raise a privacy issue, while a challenge to a benefit or licensing decision may require a separate merits or judicial review process.

16. Delegated Legislation and Administrative Accountability

Administrative agencies frequently exercise powers under delegated legislation, including regulations, rules, determinations, standards, and other legislative instruments.

Delegated legislation allows Parliament to establish a statutory framework while assigning detailed regulatory functions to ministers, agencies, or other authorised bodies.

The Legislation Act 2003 (Cth) regulates important aspects of Commonwealth legislative instruments, including registration, publication, parliamentary scrutiny, and sunsetting.

16.1. Registration and publication

Commonwealth legislative instruments generally must be registered on the Federal Register of Legislation to have legal effect, subject to the statutory framework and applicable exceptions.

Registration promotes accessibility and legal certainty. A person affected by a regulatory requirement should be able to identify the instrument and examine its legal terms.

16.2. Parliamentary disallowance

Many legislative instruments are subject to parliamentary scrutiny and disallowance under the Legislation Act 2003.

Disallowance allows Parliament to scrutinise delegated lawmaking and, where the statutory conditions are met, reject an instrument.

This mechanism is distinct from judicial review. Parliament examines whether the instrument should remain in force, while a court determines whether the instrument was legally authorised and valid.

16.3. Judicial review of delegated legislation

Delegated legislation may be challenged where it exceeds the authority conferred by the enabling Act, conflicts with superior legislation, or breaches constitutional limits.

A regulation cannot lawfully amend or override its parent statute unless Parliament has authorised that result. The instrument must remain within the scope of the power delegated.

The Legislation Act’s requirements for publication, parliamentary scrutiny, and sunsetting form part of the broader system of administrative accountability described by the Attorney-General’s Department. Attorney-General’s Department

17. Administrative Law in Migration, Social Security, and Regulatory Decision-Making

Administrative law has particularly important consequences in fields where government decisions directly affect individual status, livelihood, movement, or economic activity.

17.1. Migration and visa decisions

Migration administration involves decisions concerning visas, entry, detention, cancellation, refugee status, citizenship, and related matters.

The Migration Act 1958 (Cth) contains a detailed statutory framework, including provisions that allocate decision-making powers to ministers, delegates, and review bodies.

Merits review may be available through the ART where the legislation confers jurisdiction. Judicial review may be available where a decision is affected by jurisdictional error or another recognised legal defect.

Migration law also illustrates the importance of procedural fairness, statutory interpretation, materiality, and the relationship between administrative discretion and constitutional judicial review.

17.2. Social security and public benefits

Social security decisions may concern eligibility, payment rates, debt recovery, suspension, cancellation, and compliance obligations.

The relevant legislation defines the conditions for entitlement and the powers of the responsible agency. Internal review and ART review may be available, depending on the decision and statutory provisions.

Administrative law protects applicants against decisions made under an incorrect statutory test, without procedural fairness where required, or through an unlawful exercise of discretion.

17.3. Environmental and planning administration

Environmental and planning decisions may involve permits, development approvals, environmental assessments, land-use restrictions, and enforcement action.

The applicable legal framework may be Commonwealth, State, or Territory legislation, and sometimes a combination of these systems.

Review may be available through specialist tribunals, courts, statutory merits review, or judicial review. The availability of merits review depends on the relevant legislation and the category of decision.

17.4. Business and professional regulation

Regulators may issue licences, impose conditions, investigate compliance, suspend registrations, or impose penalties.

Administrative law requires that regulatory powers be exercised within statutory authority, for proper purposes, and through procedures required by law.

For businesses and professionals, a review mechanism may be especially important where a regulatory decision affects the ability to operate, practise, trade, or provide services.

18. Administrative Law and Parliamentary Accountability

Administrative law is closely connected with responsible government and parliamentary scrutiny.

Ministers are politically accountable to Parliament for the administration of their portfolios, while public officials are expected to act lawfully, impartially, and professionally.

Parliamentary accountability operates through several mechanisms:

• questions without notice and questions on notice;
• Senate estimates hearings;
• parliamentary committee inquiries;
• scrutiny of Bills and delegated legislation;
• reports by statutory authorities and watchdog institutions;
• examination of public expenditure and program performance;
• ministerial statements and explanations.

These mechanisms do not replace judicial review. Parliament may scrutinise the political and policy consequences of an administrative decision, while a court determines whether the decision was legally valid.

The distinction is important. A decision may be legally valid but politically controversial. Conversely, a decision may be politically supported but legally invalid because the decision-maker exceeded statutory authority.

The system of responsible government therefore operates alongside, rather than instead of, the rule of law.

19. State and Territory Administrative Law

Although Commonwealth administrative law receives considerable attention, State and Territory administrative law governs a substantial proportion of public administration in Australia.

State and Territory governments make decisions concerning planning, transport, education, health, licensing, policing, local government, environmental protection, public housing, and many other matters.

Each jurisdiction has its own statutes, courts, tribunals, ombudsmen, and integrity bodies.

19.1. State tribunals

Examples of State administrative review institutions include:

• New South Wales Civil and Administrative Tribunal (NCAT);
• Victorian Civil and Administrative Tribunal (VCAT);
• Queensland Civil and Administrative Tribunal (QCAT);
• South Australian Civil and Administrative Tribunal (SACAT);
• State Administrative Tribunal of Western Australia (SAT);
• ACT Civil and Administrative Tribunal (ACAT);
• Northern Territory Civil and Administrative Tribunal (NTCAT).

Their jurisdictions are conferred by legislation. They may review decisions concerning guardianship, tenancy, consumer disputes, licensing, planning, professional discipline, administrative decisions, and other specified matters.

The existence of a tribunal does not mean that every government decision in that jurisdiction is subject to merits review. The enabling legislation determines the scope of its authority.

19.2. State judicial review

State Supreme Courts exercise supervisory jurisdiction over administrative decision-makers and lower tribunals within their respective jurisdictions.

The constitutional significance of this role was confirmed in Kirk v Industrial Court of New South Wales. The High Court held that State Supreme Courts must retain their defining supervisory jurisdiction to correct jurisdictional error.

This principle ensures that State governments cannot create an administrative system wholly insulated from judicial supervision.

19.3. State ombudsmen and integrity institutions

Each State and Territory has its own arrangements for investigating maladministration, corruption, misconduct, and other public sector failures.

The institutions differ in jurisdiction and powers. Some combine complaint investigation with integrity oversight; others maintain separate ombudsman, anti-corruption, audit, and information commissioner bodies.

Accordingly, a person challenging a State administrative decision must identify the correct jurisdiction, statutory review mechanism, and court or tribunal with authority over the matter.

20. Access to Review, Standing, and Time Limits

The existence of a legal right to challenge administrative action does not mean that every person may bring every form of proceeding. Review mechanisms have rules governing standing, time limits, jurisdiction, and procedural requirements.

20.1. Standing

Standing concerns whether a person has a sufficient legal interest to bring a proceeding.

Under the ADJR Act, an applicant generally must be a person aggrieved by the relevant decision or conduct. The meaning of that expression is defined by the Act and interpreted by the courts.

In other judicial review proceedings, standing depends on the applicable jurisdictional rules and the nature of the relief sought.

A person who is directly affected by a decision will often have a stronger basis for standing than someone whose interest is merely ideological or general. However, public interest standing and statutory standing provisions may create additional possibilities in appropriate cases.

20.2. Time limits

Administrative review laws commonly impose strict time limits.

The ADJR Act contains time requirements for applications, subject to the statutory provisions governing extensions. The ART’s application periods depend on the legislation applicable to the original decision and may vary considerably.

Some schemes require internal review before external review. Others allow direct applications. Certain migration, taxation, social security, and regulatory matters have specialised procedures.

A person should therefore identify the relevant statute and review notice rather than assume that one general limitation period applies to all administrative decisions.

20.3. Exhaustion of alternative remedies

In some circumstances, a court may consider whether an applicant should first use an available internal or statutory review process.

This does not mean that internal review is always a strict jurisdictional prerequisite to judicial review. The legal position depends on the statute, the nature of the decision, and the principles governing the court’s jurisdiction and discretion.

Where a merits review process is available, it may provide a more appropriate route for challenging the substance of the decision. Judicial review remains concerned with legality.

20.4. Costs and practical accessibility

Judicial review proceedings may be complex and costly. Tribunal processes are generally designed to be less formal, but they can still involve procedural requirements, evidence, legal submissions, and significant delays.

The ART’s statutory framework seeks to promote accessibility and efficiency, but practical access may depend on the complexity of the matter, representation, language assistance, digital access, and the availability of support services.

21. Administrative Law, Digital Government, and Automated Decision-Making

Government administration increasingly relies on digital systems, data analytics, automated processes, and artificial intelligence-assisted tools.

These technologies may be used to assess eligibility, detect anomalies, process applications, identify compliance risks, allocate resources, and support enforcement decisions.

Automation does not remove the requirement for legality. A decision made or materially informed by an automated system must still comply with the statute, procedural fairness, privacy obligations, and other applicable legal requirements.

21.1. Statutory authority for automated decisions

An agency must have legal authority to use an automated system in making or assisting with a decision. The relevant legislation may expressly authorise computerised decision-making or permit a decision-maker to use administrative systems within the statutory framework.

The existence of a computer system does not itself create legal authority. The statutory source and limits of the decision-making power remain decisive.

21.2. Transparency and explainability

Automated decision-making can make it difficult for an affected person to understand why a decision was reached.

Administrative law therefore raises questions about access to the relevant decision-making criteria, the information used, the role of human oversight, and the ability to challenge errors.

Where reasons are required, an agency must satisfy the applicable legal obligation even if the decision was produced through an automated process.

21.3. Accuracy, bias, and procedural fairness

Automated systems may rely on incomplete or inaccurate data, reproduce historical patterns of discrimination, or apply rules in ways that do not reflect the statutory task.

The legal framework must therefore address the quality of information, the reliability of systems, appropriate human review, and the opportunity for affected persons to correct errors or respond to adverse material.

21.4. Accountability for automated decisions

The government agency remains responsible for the lawful administration of its statutory functions. It cannot avoid responsibility by attributing an unlawful result to software, an external contractor, or an algorithm.

The principles of administrative legality apply to the exercise of public power regardless of whether the decision-making process is manual, digital, or automated.

22. The Importance and Limits of Administrative Law

Administrative law provides essential protection against arbitrary or unlawful government action. It ensures that public authorities remain accountable to law and that affected persons have mechanisms through which administrative decisions can be examined and challenged.

Its importance extends beyond individual disputes. Judicial review clarifies the limits of statutory powers, merits review can correct decisions that are not the correct or preferable outcomes, ombudsman investigations identify maladministration, audits reveal institutional weaknesses, and information-access laws promote transparency.

At the same time, administrative law has limits.

Courts do not generally supervise the political wisdom of government policy. They do not ordinarily replace the discretionary judgment of an authorised administrator with their own. Tribunals can conduct merits review only where legislation confers jurisdiction. Ombudsmen and integrity bodies have defined statutory powers and cannot provide every form of legal remedy.

The system also faces practical challenges. Complex statutes, strict time limits, limited resources, large administrative caseloads, digital decision-making, and differences between Commonwealth and State review structures may make it difficult for individuals to identify the correct procedure.

The central task of administrative law is therefore to maintain a workable balance: government must have sufficient authority to administer public programs and regulate society, but that authority must remain legally bounded, procedurally fair, and institutionally accountable.

Conclusion

Australian administrative law is an essential component of the constitutional principle that government must act according to law. It regulates the exercise of public authority, establishes procedural standards for administrative decision-making, and provides mechanisms through which individuals and organisations can challenge decisions that exceed legal limits.

Its framework combines constitutional judicial supervision, statutory review, common law principles, independent tribunals, and external accountability institutions. The distinction between judicial review and merits review remains fundamental: courts determine whether a decision was made lawfully, while authorised tribunals reconsider whether it was the correct or preferable decision.

The establishment of the Administrative Review Tribunal in 2024 marked an important institutional development in Commonwealth administrative justice. At the same time, the continuing role of the Federal Court, the High Court’s jurisdiction under section 75(v), State Supreme Courts, ombudsmen, the National Anti-Corruption Commission, and audit and information institutions demonstrates that administrative accountability is not concentrated in a single body.

The challenges facing contemporary administration are also changing. Automated decision-making, extensive data collection, complex regulatory systems, and the increasing use of private contractors in public service delivery require administrative law to maintain its traditional principles while addressing new forms of governmental power.

Ultimately, administrative law does not seek to prevent government from exercising its legitimate functions. It seeks to ensure that those functions are performed within the authority granted by law, through fair and rational processes, and subject to effective review and accountability. It is therefore indispensable to the rule of law, responsible government, and public confidence in Australian institutions.

Frequently Asked Questions

1. What is administrative law in Australia?

Administrative law is the branch of public law that regulates government decision-making and the exercise of public administrative powers. It establishes legal limits, procedural requirements, review mechanisms, and accountability standards for public authorities.

2. What is the main purpose of Australian administrative law?

Its principal purpose is to ensure that government decisions are made lawfully, fairly, rationally, and within the authority conferred by legislation or other lawful sources of power. It also provides mechanisms for correcting unlawful decisions and investigating maladministration.

3. What is the difference between judicial review and merits review?

Judicial review examines whether an administrative decision was made according to law. Merits review reconsiders the substance of a decision and determines what is the correct or preferable outcome under the applicable legislation.

4. Which court reviews Commonwealth administrative decisions?

The Federal Court and the Federal Circuit and Family Court of Australia (Division 2) exercise jurisdiction under relevant statutory provisions, including the ADJR Act. The High Court also has constitutionally protected jurisdiction under section 75(v) of the Constitution in matters involving specified remedies against Commonwealth officers.

5. What is the Administrative Decisions (Judicial Review) Act 1977?

The Administrative Decisions (Judicial Review) Act 1977 (Cth) provides a statutory framework for reviewing certain administrative decisions made under an enactment. It identifies grounds of review and provides mechanisms for obtaining reasons and judicial remedies.

6. What is section 75(v) of the Australian Constitution?

Section 75(v) gives the High Court original jurisdiction in matters in which a writ of mandamus or prohibition or an injunction is sought against an officer of the Commonwealth. It protects a constitutionally entrenched minimum level of judicial review of Commonwealth executive action.

7. What is jurisdictional error?

Jurisdictional error occurs when a public decision-maker exceeds the legal authority conferred by law or fails to exercise that authority within its legal limits. Depending on the circumstances, it may render the decision legally invalid and permit judicial intervention.

8. What is procedural fairness?

Procedural fairness is the requirement that administrative decisions be made through a fair process. Depending on the circumstances, it may require an opportunity to respond to adverse information and an impartial decision-maker.

9. Does every administrative decision require a hearing?

No. The content of procedural fairness depends on the statute, the nature of the decision, and the interests affected. A written opportunity to respond may be sufficient in some cases, while more extensive procedures may be required in others.

10. What is the rule against bias?

The rule against bias requires decision-makers to act impartially. A decision may be legally defective where there is actual bias or where the circumstances give rise to a reasonable apprehension that the decision-maker might not bring an impartial mind to the matter.

11. Can an administrative decision be challenged because it is unreasonable?

Yes, in appropriate circumstances. Australian administrative law recognises legal unreasonableness as a ground of judicial review. However, courts do not intervene merely because they consider a decision harsh, unwise, or less desirable than another available outcome.

12. What is the significance of Minister for Immigration and Citizenship v Li?

The High Court’s 2013 decision in Minister for Immigration and Citizenship v Li [2013] HCA 18 is a leading authority on legal unreasonableness. It explains that statutory discretion must be exercised within legal limits and that an administrative decision may be invalid where it lacks an evident and intelligible justification in the relevant circumstances.

13. What is the Administrative Review Tribunal?

The Administrative Review Tribunal (ART) is the Commonwealth body responsible for conducting independent merits review of administrative decisions where legislation gives it jurisdiction. It commenced operation on 14 October 2024 and replaced the Administrative Appeals Tribunal.

14. Is the ART the same as the former Administrative Appeals Tribunal?

No. The ART replaced the AAT under a new legislative framework established by the Administrative Review Tribunal Act 2024 (Cth) and related legislation. The former AAT ceased operations, and unresolved matters were transferred to the ART.

15. Can the ART review every Australian Government decision?

No. The ART can review only decisions for which jurisdiction has been conferred by legislation. The applicable Act or legislative instrument determines whether a particular decision is reviewable and what procedural requirements apply.

16. Can the ART change a government decision?

Yes. Where its statutory jurisdiction permits, the ART may affirm, vary, or set aside a decision and substitute a new decision. It may also remit a matter for reconsideration where authorised.

17. Can an ART decision be challenged in court?

Yes, in appropriate circumstances. A party may have a right of appeal on a question of law under the relevant legislation or may seek judicial review where the decision is affected by jurisdictional error or another recognised legal defect.

18. What does the Commonwealth Ombudsman do?

The Commonwealth Ombudsman investigates complaints concerning administrative actions by Australian Government agencies and certain other organisations. It examines matters such as unfair treatment, unreasonable delay, defective procedures, and maladministration, and may recommend improvements.

19. What is the National Anti-Corruption Commission?

The National Anti-Corruption Commission is an independent Commonwealth integrity body established under the National Anti-Corruption Commission Act 2022 (Cth). It investigates serious or systemic corrupt conduct within the Commonwealth public sector.

20. What is the role of the Australian National Audit Office?

The Australian National Audit Office conducts independent financial and performance audits of Commonwealth government entities. Its work examines public expenditure, governance, program administration, and the effectiveness of government operations, reporting findings to Parliament and the public.

21. What is freedom of information in Australia?

Freedom of information is the statutory right to request access to documents held by government agencies, subject to exemptions and other provisions. At Commonwealth level, the principal legislation is the Freedom of Information Act 1982 (Cth).

22. Can a person challenge a refusal of access under the FOI Act?

Yes. Depending on the circumstances, the applicant may seek internal review or apply to the Australian Information Commissioner for review. Further review may be available through the ART or the courts under the applicable statutory provisions.

23. Are public officials allowed to delegate their decision-making powers?

They may delegate powers where legislation authorises delegation and the applicable requirements are satisfied. A delegate must act within the scope of the delegation and exercise the authority according to law.

24. Can a government agency rely on internal policy instead of legislation?

No. Internal policies may guide administrative discretion, but they cannot override legislation or replace the statutory decision-making task. An agency must remain willing to consider the individual circumstances of a matter where the law requires it.

25. What is a privative clause?

A privative clause is a legislative provision intended to restrict or exclude judicial review of administrative decisions. Its operation is subject to constitutional limitations, particularly the High Court’s jurisdiction under section 75(v) and the protection of jurisdictional review.

26. Can an administrative decision be overturned because the official considered irrelevant matters?

Yes, where the decision-maker takes into account a legally irrelevant consideration in a way that constitutes a recognised ground of review. Whether a matter is legally relevant depends on the proper interpretation of the statute conferring the power.

27. Do Australian States have their own administrative law systems?

Yes. Each State and Territory has its own administrative review legislation, tribunals, courts, ombudsmen, and integrity institutions. The Commonwealth ART does not replace these jurisdictional systems.

28. Can courts award compensation in judicial review proceedings?

Judicial review does not ordinarily provide damages simply because an administrative decision was unlawful. Compensation may be available through a separate legal cause of action, such as negligence, false imprisonment, misfeasance in public office, or a statutory entitlement, where the relevant requirements are satisfied.

29. Does administrative law apply to automated government decisions?

Yes. Government decisions made or assisted by automated systems must comply with applicable legislation, procedural fairness, privacy obligations, and other legal requirements. The use of software does not remove the responsibility of the public authority to act lawfully.

30. Why is administrative law important to the rule of law?

Administrative law ensures that government officials remain subject to legal limits and that individuals have mechanisms to challenge unlawful exercises of public power. It reinforces the principle that governmental authority must be exercised according to law rather than personal preference, arbitrary discretion, or administrative convenience.
