The common law doctrine of precedent is premised upon the hierarchical structure of the court system. This means that an understanding of the different elements of the hierarchy and how they relate to each other is an important component of case law research.
In Australia, there is a court hierarchy for each element of the federal system. Each state and territory has its own court hierarchy. Each of these courts deal with matters that arise out of the state or territorial jurisdiction, as well as some federal matters conferred by Commonwealth statute.
Federal courts have their own court hierarchy and deal with matters arising out of Commonwealth or national scheme legislation (section 77(iii) Commonwealth Constitution, and the Judiciary Act 1903 (Cth)).
Tribunals, such as the Administrative Appeals Tribunal (Cth) and the State Administrative Tribunal (WA) are not courts, but provide a 'quasi-judicial' function and have the task of making decisions in disputes. Appeals from tribunals to courts are binding and tribunals must follow the precedent of the court decision.
The diagram below shows an outline of the Australian courts and tribunals hierarchy. For a more detailed explanation of the relationships between the courts and tribunals, see the Australian Bureau of Statistics Year Book Australia, 2005.
