State and Territory Courts in Australia: Supreme Courts, District Courts, County Courts, and Magistrates’ Courts

State and Territory Courts in Australia: Supreme Courts, District Courts, County Courts, and Magistrates’ Courts

Introduction

Australia’s judicial system is not composed exclusively of federal courts. Alongside the High Court of Australia, the Federal Court of Australia and the Federal Circuit and Family Court of Australia, each Australian State and Territory maintains its own court system. These courts are responsible for administering a substantial proportion of Australian law, including criminal law, civil disputes, family-related matters within their jurisdiction, property disputes, personal injury claims, commercial litigation and many other areas of legal life.

State and Territory courts are particularly important because most criminal prosecutions and a large proportion of civil litigation take place within their jurisdictions. They apply State and Territory legislation, develop and interpret the common law, exercise jurisdiction conferred by Commonwealth legislation where constitutionally permitted, and form an essential part of Australia’s integrated judicial structure.

Although the court systems share a broadly recognisable hierarchy, they are not identical. Most jurisdictions have a Supreme Court at the highest State or Territory level, intermediate courts in many jurisdictions, and lower courts dealing with less serious criminal offences and less complex civil disputes. The names and structures vary: Victoria and New South Wales have County and District Courts respectively; other jurisdictions use different arrangements, and some do not have a separate intermediate court at all.

Understanding these differences is important for anyone studying Australian law. The expression State court does not refer to a single national institution. It describes courts established under the laws of individual States, each operating within its own statutory and constitutional framework. Similarly, Territory courts are established under the self-government or legislative arrangements applicable to the Australian Capital Territory and the Northern Territory.

This article examines the structure, jurisdiction and functions of State and Territory courts, explains the principal differences between Supreme Courts, intermediate courts and Magistrates’ Courts, and considers how these institutions interact with Australia’s federal judicial system.

Key Takeaways

• Australia has separate court systems in each of its six States and two mainland self-governing Territories.
• State and Territory courts are established under the constitutional and legislative arrangements applicable to their respective jurisdictions.
• The Supreme Court is generally the highest court within a State or Territory, although appeals may ultimately reach the High Court of Australia.
• District Courts and County Courts operate as intermediate courts in jurisdictions that have them. Their jurisdiction is generally broader than that of Magistrates’ Courts but narrower than that of the Supreme Court.
• Magistrates’ Courts, also known in some jurisdictions as Local Courts, deal with a large proportion of criminal proceedings and lower-value civil disputes.
• The names, divisions, monetary limits and subject-matter jurisdictions of courts differ between jurisdictions.
• State and Territory courts may exercise federal jurisdiction when Commonwealth legislation validly invests them with it.
• The High Court’s constitutional authority and the federal judicial system do not eliminate the independent institutional role of State and Territory courts.
• Appeals generally move through the relevant jurisdiction’s court hierarchy, subject to statutory rules, leave requirements and the possibility of special leave to appeal to the High Court.
• The Supreme Courts of the States and Territories are constitutionally significant institutions, particularly in relation to the exercise of federal jurisdiction and the preservation of judicial review.

1. The constitutional and institutional foundations of State and Territory courts

The Australian Constitution establishes a federal system in which legislative and executive powers are divided between the Commonwealth and the States. The judicial system reflects this division, but it does not operate as two completely separate systems. Instead, State and Territory courts perform both State or Territory judicial functions and, where validly authorised, federal judicial functions.

The Constitution’s Chapter III establishes the High Court and provides for the creation of other federal courts. It also permits the Commonwealth Parliament to invest State courts with federal jurisdiction. This arrangement is particularly important because State courts hear many disputes arising under Commonwealth legislation, even though they were not established as federal courts.

The principal constitutional provisions include:

• Section 71: vests the judicial power of the Commonwealth in the High Court, federal courts created by Parliament, and other courts invested with federal jurisdiction.
• Section 72: establishes constitutional protections concerning the appointment, tenure and remuneration of federal judges.
• Section 73: gives the High Court appellate jurisdiction over decisions of specified courts, subject to constitutional and statutory qualifications.
• Section 75: gives the High Court original jurisdiction in specified categories of matters, including certain disputes involving the Commonwealth and proceedings against Commonwealth officers.
• Section 76: permits the Commonwealth Parliament to confer additional original jurisdiction on the High Court in specified matters.
• Section 77: permits Parliament to define the jurisdiction of federal courts and to invest State courts with federal jurisdiction.

The States retain their own constitutional institutions, including their parliaments, executives and courts. State Supreme Courts are not subordinate branches of the Federal Court. They are independent superior courts within their respective jurisdictions, although their decisions remain subject to the appellate authority of the High Court where the Constitution and legislation permit an appeal.

The Territories have a different constitutional foundation. The Commonwealth Parliament has legislative power over Territories under section 122 of the Constitution. The Australian Capital Territory and the Northern Territory have self-government arrangements under Commonwealth legislation, and their courts operate within those statutory and constitutional frameworks.

The result is a system in which State and Territory courts are simultaneously local institutions and participants in a national judicial structure. The Productivity Commission describes the usual hierarchy as Supreme Courts, District or County Courts where established, and Magistrates’ Courts, while emphasising that the arrangement differs in Tasmania and the two mainland Territories. Productivity Commission+2

2. The hierarchy of State and Territory courts

Court hierarchies organise judicial work according to the seriousness, complexity and value of disputes. They also establish a structure for appeals and the development of consistent legal principles.

The general model is:

1. Supreme Court: the highest State or Territory court, exercising broad original jurisdiction and appellate functions.
2. District Court or County Court: an intermediate court in New South Wales, Victoria, Queensland, South Australia and Western Australia.
3. Magistrates’ Court or Local Court: the principal lower court, dealing with summary criminal proceedings, preliminary criminal hearings and civil disputes within its jurisdiction.

This model requires qualification. Tasmania, the Australian Capital Territory and the Northern Territory do not have a general intermediate District or County Court. Their Supreme Courts therefore exercise functions that, in other jurisdictions, are divided between the Supreme Court and an intermediate court.

Specialist courts may also exist alongside the general hierarchy. Children’s Courts, Coroners’ Courts, Drug Courts, Mental Health Courts and specialist environmental or planning courts deal with particular categories of disputes or proceedings. Their position in the judicial structure depends on the legislation establishing them.

The hierarchy is not simply administrative. It has important legal consequences. Lower courts must follow binding decisions of higher courts within the relevant hierarchy, subject to the rules of precedent. A decision of a State Supreme Court may bind lower courts in that State, while a decision of the High Court binds courts throughout Australia on the legal principles it establishes.

The hierarchy also determines where proceedings should ordinarily begin, which court can impose particular sentences, which court can make specified orders, and where an appeal may be brought.

However, jurisdiction is not determined by court rank alone. It depends on legislation. A Supreme Court may possess broad inherent or statutory jurisdiction, but particular matters may be assigned exclusively to a specialist court or tribunal. Conversely, a lower court may receive specific statutory authority to determine a matter that would otherwise appear to fall within a higher court’s general jurisdiction.

3. Supreme Courts: the superior courts of the States and Territories

Every Australian State and Territory has a Supreme Court. Each is the highest court within its own jurisdiction, subject to appeals to the High Court of Australia.

Supreme Courts are generally courts of superior jurisdiction. They possess broad authority over civil and criminal matters, except where legislation or constitutional arrangements assign jurisdiction elsewhere. Their practical workload, however, is shaped by statutory limits and the allocation of cases to lower courts.

The Supreme Courts generally perform four major functions:

• Determining the most serious criminal proceedings.
• Hearing complex and high-value civil disputes.
• Exercising appellate jurisdiction over decisions of lower courts and certain tribunals.
• Supervising the legality of decisions made by inferior courts and public authorities through judicial review and related remedies.

3.1 Original civil jurisdiction

Original jurisdiction means the authority to hear and determine a proceeding at first instance. Supreme Courts generally have broad civil jurisdiction, including disputes involving substantial financial claims, complex commercial relationships, property rights, equitable remedies, injunctions, trusts, succession and other matters requiring superior judicial authority.

They may determine disputes involving:

• Complex contractual obligations.
• Company and commercial disputes within State jurisdiction.
• Ownership and possession of land.
• Equitable claims and fiduciary duties.
• Defamation and other civil wrongs.
• Probate and the administration of deceased estates.
• Applications for injunctions and declarations.
• Judicial review of administrative decisions.
• Disputes involving substantial damages or complex questions of law.

The Supreme Court’s jurisdiction is not necessarily confined to a monetary threshold. In many jurisdictions, it has unlimited civil jurisdiction, while statutory rules and court practice determine which matters should be heard there.

For example, the New South Wales Supreme Court describes itself as having unlimited civil jurisdiction and ordinarily dealing with claims above the applicable statutory or procedural threshold, as well as complex matters and serious criminal proceedings. In Queensland, the Supreme Court Trial Division deals with civil disputes exceeding the relevant monetary threshold and the most serious criminal offences. Courts and Tribunals+1

3.2 Criminal jurisdiction

Supreme Courts hear the most serious criminal cases. These commonly include murder, manslaughter, treason and other offences assigned to the superior court by legislation.

Criminal proceedings in the Supreme Court usually involve a judge and jury, although legislation permits judge-alone trials in particular circumstances. The jury ordinarily determines whether the accused is guilty, while the judge rules on legal issues, directs the jury on the law and imposes sentence following conviction.

The precise allocation of serious offences varies. In States with intermediate courts, many serious indictable offences are heard in the District or County Court, while the Supreme Court retains jurisdiction over the gravest offences. In jurisdictions without an intermediate court, the Supreme Court assumes a wider range of trial work.

3.3 Appellate jurisdiction

Supreme Courts also act as appellate institutions. Their appeal divisions or courts of appeal review decisions made by lower courts and, where legislation permits, certain tribunals.

An appeal may concern:

• An alleged error of law.
• An incorrect application of a legal test.
• A procedural irregularity.
• A factual finding that is legally open to challenge under the applicable appeal standard.
• The adequacy or legality of a sentence.
• The exercise of judicial discretion.

An appeal is not automatically a complete rehearing. The appellate court must apply the relevant statutory framework and principles governing appellate intervention. Some appeals require leave, and different standards apply to questions of fact, law and discretionary decisions.

3.4 Supervisory jurisdiction and judicial review

Supreme Courts traditionally possess supervisory jurisdiction over inferior courts and certain public decision-makers. This authority is fundamental to the rule of law.

A person affected by an unlawful decision may, where the legal requirements are met, seek remedies such as:

• Certiorari: an order quashing a legally defective decision.
• Prohibition: an order preventing a body from acting beyond its lawful authority.
• Mandamus: an order requiring a public authority or decision-maker to perform a legal duty.
• Declarations: formal statements determining the legal rights or obligations of the parties.
• Injunctions: orders restraining conduct or requiring action.

The availability and form of these remedies depend on the court’s jurisdiction, the relevant statute and the nature of the alleged legal error.

The High Court’s decision in Kirk v Industrial Court of New South Wales (2010) 239 CLR 531 is particularly important. It recognised that State Supreme Courts must retain their defining supervisory jurisdiction to correct jurisdictional error by inferior courts and tribunals. State legislation cannot remove that essential characteristic of a State Supreme Court.

This principle is significant to the constitutional structure of Australia. State Supreme Courts are not merely ordinary statutory bodies. Their institutional role is protected by the constitutional framework governing the Australian judicial system.

4. Intermediate courts: District Courts and the County Court

Intermediate courts occupy the level between Supreme Courts and Magistrates’ or Local Courts. They are established to handle substantial criminal and civil proceedings without requiring every serious case to be heard in the Supreme Court.

Four States use the title District Court:

• New South Wales.
• Queensland.
• South Australia.
• Western Australia.

Victoria uses the title County Court.

Although the names differ, these courts perform broadly comparable functions. They hear a significant proportion of serious criminal trials and civil claims above the jurisdictional limits of lower courts. They also exercise appellate jurisdiction in some jurisdictions.

The absence of an intermediate court in Tasmania, the Australian Capital Territory and the Northern Territory means that the Supreme Court and lower court divide the work differently in those places. Productivity Commission+1

4.1 Criminal jurisdiction

District and County Courts generally hear indictable criminal offences that are too serious for summary determination in a Magistrates’ or Local Court but are not reserved exclusively for the Supreme Court.

Typical proceedings include allegations involving:

• Serious assault.
• Sexual offences.
• Robbery.
• Burglary.
• Significant fraud.
• Drug trafficking.
• Serious dishonesty offences.
• Other indictable offences allocated by statute.

The court ordinarily conducts a trial before a judge and jury. In some circumstances, a judge may determine the matter without a jury where legislation permits and the necessary procedural requirements are satisfied.

The intermediate court also determines sentencing in cases where the accused has pleaded guilty or has been found guilty after trial.

4.2 Civil jurisdiction

Intermediate courts hear civil disputes that exceed the financial or subject-matter jurisdiction of Magistrates’ Courts but do not require the Supreme Court’s original jurisdiction.

These disputes may involve:

• Contractual claims.
• Personal injury compensation.
• Property and commercial disputes.
• Negligence.
• Debt recovery.
• Claims for damages.
• Other civil proceedings assigned by statute.

The monetary limits differ substantially. A claim suitable for an intermediate court in one State may fall within the Supreme Court’s jurisdiction in another. Some courts also have special rules for particular types of claims, such as personal injury proceedings.

It is therefore unsafe to assume that a single national monetary threshold determines whether a civil claim belongs in a District or County Court. The applicable State legislation and court rules must be consulted.

4.3 Appeals and review functions

In some jurisdictions, intermediate courts hear appeals from Magistrates’ Courts. The appeal may concern a criminal conviction, sentence or civil decision, depending on the relevant legislation.

The appellate role of intermediate courts is not uniform. For example, New South Wales, Victoria and Queensland use their intermediate courts for certain appeals from lower courts, while Western Australia and South Australia generally direct criminal appeals from Magistrates’ Courts to the Supreme Court.

This variation demonstrates why the structure of Australian courts should be studied jurisdiction by jurisdiction rather than treated as a completely standardised national arrangement. Productivity Commission+2

5. Magistrates’ Courts and Local Courts: the foundation of everyday justice

Magistrates’ Courts and Local Courts are the most accessible general courts in the State and Territory systems. They handle a substantial proportion of criminal and civil proceedings and are often the first point of contact between individuals and the judicial system.

The terminology varies:

• New South Wales has a Local Court.
• The Northern Territory has a Local Court.
• Victoria, Queensland, Western Australia, South Australia, Tasmania and the ACT use the title Magistrates’ Court.

The Northern Territory is an important exception to the traditional terminology: its Local Court is now presided over by judges rather than magistrates. It should not be assumed that the title of a court necessarily identifies the judicial office of the person presiding.

Magistrates’ and Local Courts generally deal with less serious criminal matters, preliminary stages of more serious criminal proceedings, and civil disputes within their statutory limits.

5.1 Summary criminal jurisdiction

Summary offences are generally offences that can be dealt with by a judicial officer without a jury. They are usually less serious than indictable offences, although the consequences can still be significant.

Examples may include:

• Traffic and driving offences.
• Minor assaults.
• Public order offences.
• Certain theft and property offences.
• Regulatory offences.
• Some drug offences.
• Breaches of particular court orders.

The court determines guilt or innocence, hears evidence, resolves legal issues and imposes any sentence authorised by law.

Unlike a jury trial in a higher court, a summary proceeding is ordinarily determined by the magistrate or judge sitting alone.

5.2 Preliminary hearings and committal proceedings

A Magistrates’ or Local Court may also deal with the early stages of serious indictable proceedings.

The purpose of committal proceedings is to determine whether the prosecution case should proceed to trial or sentencing in a higher court. The process is governed by the legislation of the relevant jurisdiction and may involve different procedures, including statutory committal processes.

The lower court does not ordinarily conduct the final jury trial for offences reserved to a higher court. Instead, it performs a procedural and screening function before the matter progresses.

The details of committal procedure differ between States and Territories. Some jurisdictions have modified traditional committal hearings, including by limiting oral evidence or using paper-based procedures in appropriate cases.

5.3 Civil jurisdiction

Magistrates’ and Local Courts hear civil disputes involving amounts within their statutory jurisdiction. They are particularly important for ordinary disputes involving debts, contracts, property damage, consumer transactions and personal injury.

The types of claims commonly handled include:

• Unpaid invoices and debts.
• Breach of contract.
• Damage to property.
• Compensation for minor personal injuries.
• Disputes over goods and services.
• Certain tenancy-related proceedings.
• Other statutory civil claims.

The monetary limits are jurisdiction-specific and may be altered by legislation. Some courts divide civil claims into small-claims and general civil streams, with different procedural rules and costs consequences.

A lower court may also have authority to grant particular remedies, such as injunctions or orders for possession, where legislation provides for them.

5.4 Accessibility and procedural simplicity

Lower courts are designed to process large numbers of cases efficiently. Their procedures are often less formal than those of superior courts, particularly in small civil claims and summary criminal proceedings.

However, procedural simplicity should not be confused with an absence of legal complexity. Criminal charges can carry imprisonment, licence disqualification, financial penalties and other serious consequences. Civil proceedings can result in enforceable judgments, costs orders and the loss of property.

The lower courts are therefore central to access to justice. Their effectiveness depends not only on legal rules but also on court availability, interpreters, legal assistance, accessible facilities, regional sittings and appropriate procedural support.

6. How the court systems differ across the Australian jurisdictions

Although the broad hierarchy is recognisable throughout Australia, the actual allocation of judicial work differs. The following overview identifies the principal structural features of each jurisdiction.

Jurisdiction	General court structure	Principal features
New South Wales	Supreme Court, District Court, Local Court	The District Court is the intermediate court; the Local Court is the principal lower court.
Victoria	Supreme Court, County Court, Magistrates’ Court	The County Court is the intermediate court and has broad criminal and civil jurisdiction.
Queensland	Supreme Court, District Court, Magistrates’ Court	The District Court hears serious criminal matters and substantial civil claims.
Western Australia	Supreme Court, District Court, Magistrates’ Court	The Supreme Court has General and Court of Appeal divisions; the District Court has extensive criminal jurisdiction.
South Australia	Supreme Court, District Court, Magistrates’ Court	The District Court is the principal intermediate trial court.
Tasmania	Supreme Court, Magistrates’ Court	No general District or County Court; the Supreme Court exercises a broader range of trial functions.
Australian Capital Territory	Supreme Court, Magistrates’ Court	No general intermediate court; the Supreme Court and Magistrates’ Court divide the principal general jurisdiction.
Northern Territory	Supreme Court, Local Court	No intermediate court; the Local Court is presided over by judges rather than magistrates.

This structure is broadly consistent with the Productivity Commission’s 2026 account of the Australian court hierarchy. The table is a structural overview, not a complete description of every specialist jurisdiction or statutory exception. Productivity Commission+2

6.1 New South Wales

The New South Wales court system includes the Supreme Court, District Court and Local Court, alongside specialist courts and tribunals.

The Supreme Court of New South Wales is the State’s highest court. It has broad civil jurisdiction and deals with the most serious criminal cases, including murder and treason. Its appellate structure includes the Court of Appeal and the Court of Criminal Appeal.

The District Court of New South Wales is the intermediate court. It hears a substantial proportion of serious criminal proceedings and civil claims above the Local Court’s jurisdiction. It also hears certain appeals from the Local Court.

The Local Court of New South Wales deals with summary criminal proceedings, committal proceedings, civil claims within its monetary jurisdiction and a range of other statutory matters. Specialist arrangements include the Children’s Court and the Coroners Court.

The State’s court structure illustrates the division of judicial labour: the Local Court processes a high volume of ordinary proceedings, the District Court handles more serious trials and substantial civil claims, and the Supreme Court deals with the most serious and complex matters and significant appeals. Courts and Tribunals+1

6.2 Victoria

Victoria has a Supreme Court, County Court and Magistrates’ Court.

The Supreme Court of Victoria is the State’s superior court. It has a Trial Division and Court of Appeal. The Trial Division hears the most serious criminal matters and complex civil disputes, while the Court of Appeal hears appeals from specified courts and tribunals.

The County Court of Victoria is the intermediate court. It hears a broad range of indictable criminal offences, except those reserved by law for the Supreme Court. It also hears substantial civil disputes and certain appeals.

The Magistrates’ Court of Victoria handles summary criminal matters, committal proceedings and civil disputes within its jurisdiction. It also administers specialist lists and divisions dealing with matters such as family violence, personal safety, and other statutory proceedings.

Victoria’s County Court is the only court in Australia using that name as the general intermediate court. Its functions are broadly comparable to those of the District Courts in other States.

6.3 Queensland

Queensland’s court hierarchy comprises the Supreme Court, District Court and Magistrates’ Court.

The Supreme Court of Queensland consists of a Trial Division and a Court of Appeal. The Trial Division deals with the most serious criminal proceedings, including murder and manslaughter, and civil disputes above the relevant jurisdictional threshold. The Court of Appeal hears appeals from lower courts and from decisions of the Supreme Court where the statutory framework permits.

The District Court of Queensland deals with serious criminal offences that fall below the Supreme Court’s exclusive or reserved jurisdiction, as well as substantial civil disputes. It also exercises appellate functions.

The Magistrates’ Court of Queensland is the first level of the general court system. It deals with most criminal proceedings at their initial stage and determines summary offences. It also hears civil claims within its statutory monetary limit. Queensland Courts report that the Magistrates’ Court handles the great majority of court matters, illustrating the practical importance of lower-court jurisdiction. Queensland Courts+2

6.4 Western Australia

Western Australia has a Supreme Court, District Court and Magistrates’ Court.

The Supreme Court of Western Australia is the State’s highest court and its principal appellate court. It is divided into the General Division and the Court of Appeal. The General Division hears complex civil proceedings and the most serious criminal cases, while the Court of Appeal determines appeals.

The District Court of Western Australia is an intermediate trial court. It hears serious criminal matters, including sexual offences, serious assaults, fraud and drug offences, subject to the offences reserved for the Supreme Court. It also deals with substantial civil claims and certain appeals from the Magistrates’ Court.

The Magistrates’ Court of Western Australia handles the majority of adult criminal proceedings at first instance, including summary matters and preliminary stages of more serious cases. It also hears civil claims within its jurisdiction and operates specialist lists and programs.

Western Australia’s allocation of serious criminal offences was significantly affected by the Court Jurisdiction Legislation Amendment Act 2018, which came into operation in 2019. The reforms transferred a wider range of indictable offences to the District Court while retaining the most serious offences for the Supreme Court. supremecourt.wa.gov.au+2

6.5 South Australia

South Australia has a Supreme Court, District Court and Magistrates’ Court, together with specialist courts.

The Supreme Court of South Australia is the superior court of the State. It hears the most serious criminal cases, including murder and treason, as well as complex civil matters and appeals.

The District Court of South Australia is the principal intermediate trial court. It hears a wide range of indictable criminal matters and substantial civil proceedings. It plays a particularly important role in the trial of serious offences that do not fall within the Supreme Court’s reserved jurisdiction.

The Magistrates’ Court of South Australia deals with summary criminal proceedings, preliminary criminal matters and civil disputes within its jurisdiction. The State also has specialist courts, including the Youth Court, Coroner’s Court and Environment, Resources and Development Court.

The existence of specialist courts demonstrates that the judicial system is not simply a three-level ladder. Certain subject areas require a distinct institutional structure or specialised procedures. CAA+1

6.6 Tasmania

Tasmania has two principal general levels of courts: the Supreme Court and the Magistrates’ Court. It does not have a general intermediate District or County Court.

The Supreme Court of Tasmania exercises civil and criminal jurisdiction under Tasmanian law and certain federal laws. It hears serious criminal proceedings, complex civil disputes and appeals from lower courts.

The Magistrates’ Court of Tasmania is the State’s busiest court. It includes several divisions dealing with criminal and general matters, civil disputes, administrative appeals, children, youth justice and coronial proceedings.

The absence of an intermediate court means that the Supreme Court performs work that is allocated to District or County Courts in other States. The Magistrates’ Court also has a range of specialised functions, including the determination of certain civil claims and preliminary hearings for serious criminal matters. Department of Justice+2

6.7 Australian Capital Territory

The ACT has a Supreme Court and Magistrates’ Court, as well as specialist judicial and tribunal arrangements. It does not have a general intermediate court.

The Supreme Court of the Australian Capital Territory exercises superior jurisdiction in civil and criminal matters and hears appeals from the Magistrates’ Court and other bodies where legislation provides.

The Magistrates’ Court of the ACT deals with summary criminal proceedings, preliminary matters, civil claims within its jurisdiction and a range of specialist proceedings. The Children’s Court and Coroner’s Court operate within the ACT’s wider judicial arrangements.

Because the ACT is a Territory rather than a State, its constitutional and legislative position differs from that of the six States. Its courts are nevertheless important judicial institutions and may exercise federal jurisdiction where validly conferred.

6.8 Northern Territory

The Northern Territory has a Supreme Court and Local Court. It does not have a general intermediate District Court.

The Supreme Court of the Northern Territory is the Territory’s superior court. It exercises original and appellate jurisdiction in civil and criminal matters, subject to statutory exclusions and the jurisdiction of other courts.

The Local Court of the Northern Territory deals with summary criminal proceedings, committal proceedings, civil claims within its jurisdiction, and other statutory matters. Its work includes proceedings in regional and remote locations.

An important institutional distinction is that the Northern Territory Local Court is now presided over by judges. The Territory’s court system no longer uses sitting magistrates in the way that other Australian jurisdictions do. The Local Court also includes specialist functions such as youth justice and coronial work. Supreme Court NT+2

7. Specialist courts and divisions

General courts cannot always provide the most suitable forum for every type of legal dispute. Australian jurisdictions therefore establish specialist courts, divisions and lists to address particular subject areas.

These institutions may be separate courts or specialised parts of a broader court. Their jurisdiction is determined by legislation, and their position in the judicial hierarchy is not necessarily identical.

7.1 Children’s Courts and youth justice jurisdictions

Children’s Courts deal with legal proceedings involving children and young people. Their jurisdiction commonly includes youth criminal proceedings and child protection matters.

Youth justice systems generally recognise that children and young people require procedures and sentencing approaches different from those applied to adults. The relevant legislation may restrict publication of identifying information, provide for closed hearings in particular circumstances, and establish specialised sentencing options.

A Children’s Court may operate as a separate court or as a division of a Magistrates’ Court. Its precise structure varies by jurisdiction.

7.2 Coroners’ Courts

Coroners’ Courts investigate deaths and, in some jurisdictions, fires or other incidents within the statutory jurisdiction of the coroner.

A coronial investigation is not a criminal trial. Its purpose is generally to establish matters such as:

• The identity of the deceased.
• The circumstances of the death.
• The medical cause of death.
• The place and time of death.
• Whether recommendations should be made to prevent similar deaths.

A coroner may conduct an inquest where the legislation requires or permits one. The process may examine systemic failures, institutional practices, public safety and the circumstances surrounding a death.

A coronial finding does not itself establish criminal guilt. If evidence suggests that a criminal offence may have occurred, the matter may be referred to the relevant prosecuting or investigative authority.

7.3 Drug Courts and specialist criminal lists

Some jurisdictions operate Drug Courts or specialist programs for eligible offenders whose offending is connected to substance dependence.

These programs may combine judicial supervision, treatment requirements, regular reporting and structured incentives or sanctions. Their purpose is to address factors associated with repeated offending while maintaining public safety and accountability.

Specialist lists may also deal with family violence, sexual offences, complex criminal proceedings or other matters requiring particular expertise and case-management arrangements.

7.4 Mental health and specialist statutory courts

Mental health courts or specialist mental health jurisdictions address particular legal questions involving people with mental illness or cognitive impairment. Their functions may include determining fitness to stand trial, criminal responsibility, treatment-related orders or other matters assigned by legislation.

Queensland, for example, has a Mental Health Court within its specialist court structure. Other jurisdictions may allocate comparable questions to different courts or statutory decision-makers.

7.5 Planning, environmental and land courts

Some States have established specialist courts or divisions for disputes involving planning, land use, environmental regulation and development.

These matters may involve technical evidence, statutory planning schemes, environmental assessments, land valuation and administrative decisions. Specialist jurisdiction allows the legal system to develop procedures and expertise suited to those disputes.

The existence of specialist courts does not mean that all disputes involving a particular subject automatically belong there. The relevant statute determines whether the specialist body has exclusive jurisdiction, concurrent jurisdiction or a limited appellate role.

8. Original jurisdiction, appellate jurisdiction and supervisory jurisdiction

A clear understanding of court structure requires distinguishing three forms of judicial authority.

8.1 Original jurisdiction

Original jurisdiction is the power to hear a matter at first instance. A court exercising original jurisdiction receives evidence, determines relevant facts, applies the law and makes an initial decision.

For example, a civil claim may begin in a Magistrates’ Court if its value falls within the court’s monetary jurisdiction. A serious indictable criminal charge may begin procedurally in a Local or Magistrates’ Court but proceed to a higher court for trial.

The court in which a matter begins is not necessarily the court that will determine every aspect of it. Preliminary proceedings, committal processes and interlocutory applications may occur in one court before the substantive dispute is determined elsewhere.

8.2 Appellate jurisdiction

Appellate jurisdiction is the authority to review a decision made by another court or tribunal.

An appeal may challenge a conviction, sentence, civil judgment or other decision. The applicable legislation determines:

• Whether an appeal is available.
• Which court can hear it.
• Whether leave is required.
• The time limit for filing.
• Whether the appeal concerns law, fact, sentence or procedure.
• What remedies the appellate court may grant.

An appellate court may dismiss an appeal, affirm the decision, vary an order, set aside the decision or order a new hearing. The available outcomes depend on the legislation and the nature of the alleged error.

8.3 Supervisory jurisdiction

Supervisory jurisdiction concerns the authority of a superior court to ensure that inferior courts and certain public bodies act within the limits of their legal powers.

It is closely associated with judicial review and the control of jurisdictional error. A court exercising supervisory jurisdiction does not simply substitute its preferred view of the merits for that of the original decision-maker. It examines whether the decision was legally authorised and reached through a lawful process.

The distinction between appeal and judicial review is important. An appeal may permit reconsideration of factual or legal conclusions within the applicable appellate framework. Judicial review ordinarily focuses on legality, jurisdiction and procedural fairness rather than whether the decision was the best or most reasonable one on its merits.

9. Federal jurisdiction in State and Territory courts

One of the most distinctive features of Australian judicial organisation is that State and Territory courts may exercise federal jurisdiction.

Section 77(iii) of the Constitution allows the Commonwealth Parliament to invest State courts with federal jurisdiction. The Judiciary Act 1903 (Cth) is central to this arrangement.

As a result, a State court may hear a dispute arising under Commonwealth legislation, provided the court has been validly invested with the relevant jurisdiction and the matter falls within its statutory authority.

Examples may include proceedings involving:

• Commonwealth criminal offences.
• Federal employment legislation.
• Commonwealth consumer and competition laws.
• Bankruptcy and insolvency matters where jurisdiction is conferred.
• Certain migration-related matters.
• Federal statutory rights and obligations.
• Other matters arising under Commonwealth legislation.

The fact that a State court is exercising federal jurisdiction does not transform it into a federal court. It remains a State court, established under State law and operating within the State’s institutional framework.

However, when it exercises federal jurisdiction, it must apply the relevant Commonwealth law and follow the constitutional and statutory rules governing that jurisdiction.

9.1 State courts as part of the integrated judicial system

The High Court has recognised that State courts are important components of the national judicial structure. Their ability to exercise federal jurisdiction depends on their institutional suitability and compliance with constitutional requirements.

The decision in Kable v Director of Public Prosecutions (NSW) (1996) 189 CLR 51 established an important constitutional limitation: State legislation cannot confer functions on a State court that are incompatible with its institutional integrity as a court capable of exercising federal jurisdiction.

The principle does not mean that every State court must operate identically to a federal court. Rather, it protects essential characteristics of judicial institutions, including independence and the capacity to exercise judicial power according to law.

The High Court subsequently developed this doctrine in cases such as Fardon v Attorney-General (Qld) (2004) 223 CLR 575 and International Finance Trust Co Ltd v New South Wales Crime Commission (2009) 240 CLR 319.

9.2 Federal jurisdiction and the importance of jurisdictional limits

The presence of federal jurisdiction does not give State courts unlimited authority over every Commonwealth dispute. The relevant legislation must confer jurisdiction, and constitutional limits must be respected.

A court must identify the source of its jurisdiction before determining a matter. If it acts outside that authority, its decision may be challenged through appeal or judicial review, depending on the nature of the error and the available remedy.

The distinction is particularly important in administrative law. A State Supreme Court may review the legality of certain State administrative decisions under State law and may also exercise jurisdiction concerning federal matters where constitutionally and statutorily authorised.

10. Judicial precedent and the relationship between courts

Court hierarchies support consistency through the doctrine of precedent, also known as stare decisis.

The central principle is that lower courts must follow the binding legal principles established by higher courts in the same judicial hierarchy. This promotes stability, predictability and equality before the law.

A distinction must be drawn between the binding part of a judgment and observations that are not essential to the decision.

• Ratio decidendi: the legal principle necessary to determine the case. It is the part of a judgment that may bind later courts.
• Obiter dicta: observations made by a judge that are not essential to the decision. They may be persuasive but are not ordinarily binding.

Within a State hierarchy, a Magistrates’ Court must generally follow relevant binding decisions of the District or County Court and Supreme Court, subject to the precise rules governing precedent and appellate authority.

A State Supreme Court is bound by the High Court on questions of Australian law. It is also required to respect applicable appellate decisions from its own hierarchy.

The position of decisions from other State Supreme Courts is different. Such decisions are generally persuasive rather than binding, although they may be highly influential, especially where the same statutory language or common law principle is involved.

Federal and State courts also interact through precedent. A State court exercising federal jurisdiction must apply binding High Court authority and relevant federal appellate authority according to the rules governing the particular jurisdiction.

The national role of the High Court is therefore central to the consistency of Australian law. It ensures that fundamental legal questions do not develop into entirely separate systems of State law.

11. Appeals from State and Territory courts to the High Court

The High Court of Australia stands at the apex of the national judicial system. It hears appeals from State and Territory Supreme Courts and other courts within the constitutional and statutory framework.

Section 73 of the Constitution provides the High Court with appellate jurisdiction in relation to specified decisions, including decisions of State Supreme Courts and other courts from which Parliament has authorised appeals.

However, an appeal to the High Court is not automatic. In most cases, a party must obtain special leave to appeal under the Judiciary Act 1903 (Cth).

The High Court’s special-leave jurisdiction is selective. It is not intended to provide a further ordinary appeal in every case where a party is dissatisfied with the result.

The Court considers whether the case raises issues of public importance, involves conflicting judicial authority, concerns a matter requiring authoritative determination, or otherwise warrants consideration in the interests of the administration of justice.

This structure preserves the High Court’s capacity to resolve questions of national legal significance while allowing State and Territory courts to determine the great majority of disputes conclusively.

A party who loses in a Magistrates’ or Local Court will ordinarily need to follow the relevant appeal route within the State or Territory system. Only after the necessary intermediate or Supreme Court stages, and subject to the applicable statutory requirements, might an appeal to the High Court be available.

12. Judicial independence in State and Territory courts

Judicial independence is a fundamental condition of the rule of law. Courts must decide disputes impartially, free from improper influence by governments, parliaments, political parties, litigants or other external actors.

State and Territory judges and magistrates are appointed under the applicable legislation and constitutional arrangements of their jurisdiction. Their tenure, remuneration, disciplinary processes and removal are governed by the relevant laws.

The constitutional position of State judicial officers is not identical to that of federal judges under section 72 of the Commonwealth Constitution. Nevertheless, State constitutional arrangements and the common law protect judicial independence.

The High Court has also developed constitutional limits on State legislation that would undermine the institutional integrity of State courts. The Kable doctrine is particularly important in this respect.

Judicial independence is not an entitlement to act without accountability. Judges must apply the law, provide reasons where required, comply with procedural obligations and observe applicable judicial conduct standards. Complaints and disciplinary processes may exist, but they must be structured so that they do not become instruments of political pressure or interference with judicial decision-making.

12.1 Judicial officers and their functions

The terminology used for judicial officers varies across the court system.

• Judges generally preside over Supreme Courts and intermediate courts.
• Magistrates preside over Magistrates’ Courts in most jurisdictions.
• Judges preside over the Northern Territory Local Court.
• Registrars and judicial registrars perform functions assigned by legislation and court rules, including procedural, case-management and some delegated decision-making functions.

The precise powers of registrars differ. They may determine specified interlocutory matters, manage proceedings, assess costs or perform other functions that do not require the exercise of judicial power reserved to a judge.

13. Civil and criminal proceedings: different functions within the same hierarchy

State and Territory courts hear both civil and criminal proceedings, but the nature of the parties, issues and remedies differs.

13.1 Civil proceedings

Civil proceedings generally concern disputes between individuals, companies, organisations or public authorities. The claimant seeks a legal remedy rather than punishment for a criminal offence.

Common civil claims include:

• Breach of contract.
• Negligence and personal injury.
• Property disputes.
• Debt recovery.
• Defamation.
• Consumer disputes.
• Equitable claims.
• Commercial disputes.

The court determines whether the claimant has established the legal elements of the claim, ordinarily applying the civil standard of proof: the balance of probabilities.

Available remedies may include damages, injunctions, declarations, specific performance, possession orders and other forms of relief authorised by law.

13.2 Criminal proceedings

Criminal proceedings concern allegations that a person has committed an offence against the law. The prosecution must prove the offence beyond reasonable doubt.

The accused is entitled to the protections provided by legislation, common law and applicable constitutional principles. These include the presumption of innocence, the right to a fair trial and the requirement that criminal guilt be determined according to law.

The division between summary and indictable offences helps determine which court will hear the case. Summary matters are generally determined in a Magistrates’ or Local Court. More serious indictable offences are generally transferred to a District, County or Supreme Court for trial or sentencing, depending on the relevant jurisdiction.

13.3 Jury trials

Juries are an important feature of serious criminal proceedings in Australian courts. In ordinary jury trials, the jury determines the accused’s guilt or innocence while the judge determines questions of law and imposes sentence if the accused is convicted.

The availability of jury trials, the number of jurors, and the circumstances in which a judge-alone trial may be ordered are governed by the relevant legislation.

Most Magistrates’ and Local Court proceedings are determined by a judicial officer sitting alone, without a jury.

14. Court administration, case management and access to justice

The operation of courts depends on more than judges and legal doctrine. Court registries, administrative staff, procedural rules, technology, legal assistance services and physical facilities all influence whether justice is accessible and effective.

Court administration commonly includes:

• Filing and managing court documents.
• Listing hearings and trials.
• Maintaining court records.
• Issuing procedural directions.
• Managing interpreters and accessibility arrangements.
• Supporting jury administration.
• Providing information to court users.
• Coordinating remote and regional sittings.

Modern courts increasingly use electronic filing, online case information, video hearings and digital court records. These systems can reduce travel and administrative costs, particularly for regional litigants. However, they also create challenges for people who lack reliable internet access, suitable technology or digital literacy.

14.1 Case management

Case management is intended to ensure that proceedings are resolved fairly, efficiently and proportionately.

Courts may use directions hearings, timetables, disclosure requirements, mediation, settlement conferences and limits on unnecessary interlocutory disputes.

The objective is not simply speed. A court must balance efficiency with procedural fairness, the right to present a case and the need for a just outcome.

14.2 Legal representation and self-represented litigants

A person may be legally entitled to represent themselves in many proceedings, but litigation can involve complex rules of evidence, procedure and substantive law.

Self-represented litigants may face difficulties with:

• Identifying the correct court.
• Drafting pleadings and applications.
• Understanding evidence requirements.
• Meeting filing deadlines.
• Complying with court directions.
• Presenting legal arguments.
• Understanding costs risks and enforcement procedures.

Legal aid commissions, community legal centres, pro bono schemes and court-based information services can assist eligible people, although the availability of assistance varies according to jurisdiction, subject matter and financial circumstances.

14.3 Regional and remote justice

Geography presents particular challenges in a country as large as Australia. Many courts operate circuit or regional sittings to serve communities outside major cities.

This is especially important in the Northern Territory, Western Australia, Queensland and other jurisdictions with large regional populations. Remote sittings can improve access to justice, but distance, transport, interpreter availability, legal representation and cultural barriers may continue to affect participation.

15. Indigenous justice and the State and Territory court systems

Aboriginal and Torres Strait Islander peoples have distinctive legal, cultural and historical relationships with the Australian justice system. The effects of colonisation, dispossession, discriminatory laws and institutional practices remain relevant to contemporary questions of access to justice and criminal justice outcomes.

State and Territory courts operate within a legal system that must recognise the equal application of law while responding appropriately to the circumstances of Indigenous defendants, victims, families and communities.

A number of jurisdictions have developed specialist approaches, including:

• Koori Courts in Victoria and related Indigenous sentencing initiatives in other jurisdictions.
• Circle sentencing in New South Wales and other jurisdictions.
• Murri Courts in Queensland.
• Nunga Courts in South Australia.
• Aboriginal sentencing courts and community-based justice initiatives in other jurisdictions.

These models differ in their legal foundations and procedures. Some involve Elders or respected community members participating in sentencing discussions; others adapt the court environment or provide structured opportunities for community input.

Such processes do not create a separate criminal law for Indigenous Australians. They operate within the applicable statutory framework and judicial authority. Their purpose is generally to improve participation, cultural understanding, procedural legitimacy and the appropriateness of sentencing outcomes.

The legal system must also address broader issues, including disproportionate rates of imprisonment, access to legal representation, language and interpretation, remoteness, child protection proceedings and the treatment of Indigenous people in custody.

16. The relationship between courts and tribunals

Australian legal systems contain both courts and tribunals, but the two should not be treated as interchangeable.

Courts are judicial institutions exercising judicial power. Tribunals are generally statutory bodies created to determine particular disputes, conduct merits review or make specialised administrative decisions.

Examples include:

• Civil and administrative tribunals.
• State and Territory human rights or equal opportunity bodies.
• Planning and environmental review bodies.
• Workers’ compensation tribunals.
• Residential tenancy tribunals.
• Professional disciplinary bodies.

A tribunal may be required to apply legal standards and provide procedural fairness, but its institutional role differs from that of a court.

Some tribunals conduct merits review, reconsidering the facts and law and deciding the correct or preferable decision within the statutory framework. Courts ordinarily exercise judicial review, determining whether the decision was legally valid, unless a statute gives them a broader appellate function.

Appeals from tribunal decisions may be available to a court on a question of law, or a court may have jurisdiction to review the legality of a tribunal’s decision. The relevant statute determines the route.

The distinction matters because a person dissatisfied with an administrative decision may have to seek merits review before a tribunal, judicial review in a court, or both in the sequence prescribed by law.

17. Why the State and Territory court structure matters

The State and Territory court systems are not secondary institutions in Australian law. They are central to the administration of justice and to the practical operation of the federal system.

Their importance can be understood through several connected functions.

First, they provide the principal forums for applying State and Territory legislation. Criminal law, property law, civil liability, local regulatory offences, family violence proceedings and many other matters are administered through these courts.

Second, they provide access to justice at different levels. Magistrates’ and Local Courts handle large volumes of ordinary disputes, while intermediate and Supreme Courts provide forums for more serious or complex proceedings.

Third, they develop the common law. Judicial decisions in State courts contribute to the body of legal principles that governs civil liability, property, procedure, remedies and other fields. The High Court ultimately provides authoritative national resolution of questions within its jurisdiction.

Fourth, they exercise federal jurisdiction. State courts are therefore part of the practical machinery through which Commonwealth legislation is enforced and applied.

Finally, their institutional independence is a constitutional safeguard. The High Court’s decisions in Kable and Kirk demonstrate that State courts must retain essential characteristics of judicial institutions and their defining supervisory role.

The system is not perfectly uniform. Differences in court names, monetary thresholds, appeal routes, specialist jurisdictions and regional arrangements reflect the legal autonomy of the States and the distinct constitutional position of the Territories. These variations are not necessarily defects. They are features of a federal system in which local institutions administer justice within a common constitutional framework.

Conclusion

State and Territory courts form the everyday foundation of Australia’s judicial system. They determine the overwhelming range of ordinary criminal and civil disputes, interpret and apply State and Territory legislation, develop the common law and exercise federal jurisdiction where validly conferred.

The Supreme Courts occupy the highest level within each State and Territory. They exercise broad original, appellate and supervisory jurisdiction and play a particularly important role in protecting the legality of governmental and judicial action. District Courts and the Victorian County Court provide an intermediate level for serious criminal trials and substantial civil litigation. Magistrates’ and Local Courts handle the majority of ordinary proceedings, including summary criminal cases, preliminary hearings and lower-value civil claims.

The structure is not identical throughout the country. Tasmania, the ACT and the Northern Territory lack a general intermediate court, while the Northern Territory’s Local Court is presided over by judges. Specialist courts and divisions also address particular areas of law, including youth justice, coronial investigations, mental health, family violence and environmental disputes.

The most important constitutional feature is that State and Territory courts are not isolated local institutions. Through section 77(iii) of the Constitution and Commonwealth legislation, they form an integral part of Australia’s integrated judicial system. Their independence, jurisdiction and institutional integrity are therefore essential not only to State justice but also to the operation of Australian federalism and the rule of law.

Frequently Asked Questions (FAQs)

1. How many levels of courts are there in Australia?

Most States have three general levels: Supreme Court, District or County Court, and Magistrates’ Court. Tasmania, the Australian Capital Territory and the Northern Territory generally have two levels: a Supreme Court and a lower Magistrates’ or Local Court.

2. What is the highest State court in Australia?

Each State and Territory has its own Supreme Court, which is the highest court within that jurisdiction. The High Court of Australia is the highest court nationally and the final court of appeal.

3. Is the Supreme Court a federal court?

No. State and Territory Supreme Courts are established under the relevant State or Territory legal framework. However, they may exercise federal jurisdiction when validly invested with it under section 77(iii) of the Commonwealth Constitution.

4. What is the difference between a District Court and a County Court?

They perform broadly equivalent functions. Victoria uses the name County Court, while New South Wales, Queensland, South Australia and Western Australia use District Court. Their precise criminal, civil and appellate jurisdictions differ.

5. Does every Australian State have a District or County Court?

No. Tasmania does not have a general intermediate court. The six States do not all have identical court structures: Victoria has a County Court, four States have District Courts, and Tasmania has no general intermediate court.

6. Does the Northern Territory have a Magistrates’ Court?

No. The Northern Territory has a Local Court. It is now presided over by judges rather than magistrates, making it institutionally different from the Magistrates’ Courts operating in most other Australian jurisdictions.

7. What cases are heard in a Magistrates’ Court?

Magistrates’ Courts generally hear summary criminal offences, preliminary proceedings for serious criminal charges and civil disputes within their statutory monetary limits. They may also exercise specialist jurisdiction over matters such as family violence, youth justice and certain administrative proceedings.

8. Are there juries in Magistrates’ Courts?

Generally, no. Magistrates’ and Local Court proceedings are ordinarily determined by a magistrate or judge sitting alone. Jury trials are more commonly associated with serious indictable criminal proceedings in intermediate and Supreme Courts.

9. What is the difference between summary and indictable offences?

Summary offences are generally less serious offences dealt with by a judicial officer without a jury. Indictable offences are generally more serious and may require trial in a higher court, often before a judge and jury. Some indictable offences may nevertheless be dealt with summarily where legislation permits.

10. Where are murder cases heard in Australia?

Murder cases are ordinarily tried in a State or Territory Supreme Court. The allocation of other serious criminal offences varies, and many are tried in District or County Courts where those courts exist.

11. Can a Supreme Court hear appeals?

Yes. Supreme Courts have appellate jurisdiction, usually through a Court of Appeal or Court of Criminal Appeal. They hear appeals from lower courts and certain tribunals where the relevant legislation provides.

12. Can a person appeal directly from a Magistrates’ Court to the High Court?

Ordinarily, no. The person must follow the appeal route established by the relevant State or Territory legislation. A further appeal to the High Court may be possible in an appropriate case, usually subject to special leave.

13. Are decisions of State Supreme Courts binding throughout Australia?

A State Supreme Court’s decisions generally bind lower courts within its own hierarchy, subject to applicable rules. Decisions of other State Supreme Courts are generally persuasive rather than binding. Decisions of the High Court are binding nationally.

14. What is the difference between original and appellate jurisdiction?

Original jurisdiction is the authority to hear a matter for the first time. Appellate jurisdiction is the authority to review a decision made by another court or tribunal.

15. What is supervisory jurisdiction?

Supervisory jurisdiction is the authority of a superior court to ensure that inferior courts and certain public decision-makers act within their lawful powers. It is closely associated with judicial review and remedies for jurisdictional error.

16. Can State courts hear cases involving Commonwealth law?

Yes. Section 77(iii) of the Constitution permits the Commonwealth Parliament to invest State courts with federal jurisdiction. Consequently, State courts may hear proceedings arising under Commonwealth legislation, provided the relevant jurisdiction has been validly conferred.

17. Does a State court become a federal court when exercising federal jurisdiction?

No. It remains a State court, even when exercising federal jurisdiction. Its institutional identity does not change, although it must apply the relevant Commonwealth law and comply with the constitutional requirements governing federal jurisdiction.

18. What are specialist courts?

Specialist courts are institutions or divisions established to deal with particular categories of legal matters. Examples include Children’s Courts, Coroners’ Courts, Drug Courts, Mental Health Courts and specialist planning or environmental courts.

19. What is the difference between a court and a tribunal?

A court is a judicial institution exercising judicial power. A tribunal is generally a statutory body established to determine particular disputes or review administrative decisions. Some tribunals conduct merits review, while courts ordinarily focus on judicial determination and legality review.

20. What is the Kable principle?

The Kable principle is a constitutional doctrine that prevents State legislation from conferring functions on State courts that are incompatible with their institutional integrity as courts capable of exercising federal jurisdiction. It protects essential judicial characteristics, including independence and impartiality.

21. Why is the Kirk decision important?

In Kirk v Industrial Court of New South Wales (2010), the High Court recognised that State Supreme Courts must retain their defining supervisory jurisdiction to correct jurisdictional error by inferior courts and tribunals. This is an important protection of the constitutional role of State Supreme Courts.

22. Are State and Territory judges independent?

Yes. Judicial independence is a fundamental feature of the Australian legal system. State and Territory judges and magistrates must determine cases impartially, without improper interference from the executive or legislature. Their appointment, tenure and removal arrangements are governed by the applicable legal framework.

23. What is a committal proceeding?

A committal proceeding is a preliminary process in which a Magistrates’ or Local Court deals with an indictable criminal matter before it proceeds to a higher court. Its purpose and procedure depend on the legislation of the relevant jurisdiction.

24. Can a person represent themselves in a State or Territory court?

In many proceedings, individuals may represent themselves. However, criminal trials and complex civil disputes can involve demanding procedural and evidentiary rules. Legal assistance may be available through legal aid, community legal centres or pro bono services, depending on eligibility and the nature of the case.

25. Are all State and Territory court hearings open to the public?

The general principle is that court proceedings are open to the public. However, legislation and judicial orders may restrict access or publication in particular circumstances, including some youth justice, family violence, sexual offence and child protection proceedings.

26. What is the role of the High Court in relation to State courts?

The High Court is the final appellate court in Australia. It hears qualifying appeals from State and Territory courts, resolves important constitutional questions and establishes authoritative legal principles binding on courts throughout the country.

27. What is the difference between a State Supreme Court and the Federal Court?

A State Supreme Court is established under State law and has broad jurisdiction within that State, including State civil and criminal matters. The Federal Court is a Commonwealth court established under federal legislation and has jurisdiction over specified matters arising under Commonwealth law. Their jurisdictions can overlap in certain areas, but neither is simply a branch of the other.

28. Why do Tasmania, the ACT and the Northern Territory not have intermediate courts?

Their judicial structures allocate work differently. Rather than dividing general jurisdiction among three levels, they rely principally on a Supreme Court and a lower court. The Supreme Court therefore performs some functions that are assigned to District or County Courts in other jurisdictions.

29. Are decisions of a State Supreme Court subject to review by another State Supreme Court?

Not ordinarily. A State Supreme Court is not an appellate court for another State’s Supreme Court. Appeals from State Supreme Courts may proceed to the High Court where the constitutional and statutory requirements are satisfied.

30. Why is the Australian court hierarchy important?

The hierarchy allocates cases according to their seriousness, complexity and statutory jurisdiction. It also establishes appeal routes, supports consistent legal interpretation through precedent and allows superior courts to supervise the legality of decisions made by lower courts.
