What is the rule of law in Australia?

The rule of law in Australia, looked at as a working institutional system, is delivered through a hierarchy of independent courts, a body of publicly accessible legislation and case law, statutory rules for judicial review of executive action, and operational safeguards that insulate judges from political pressure. The system is anchored in Chapter III of the Constitution, which vests federal judicial power exclusively in the High Court and other federal courts created by Parliament.

Court structure follows a clear hierarchy. At federal level the High Court of Australia sits above the Federal Court of Australia, the Federal Circuit and Family Court of Australia, and specialist tribunals such as the Administrative Review Tribunal (which replaced the Administrative Appeals Tribunal in October 2024). In each state and territory a Supreme Court sits at the top, with District or County courts (in the larger states) and Magistrates' or Local courts beneath. Higher courts bind lower courts through the doctrine of precedent, and the High Court binds all other Australian courts. Cases proceed in open court with judgments published on AustLII and on each court's website.

Judicial independence is protected by specific institutional mechanisms. Federal judges hold office under section 72 of the Constitution until age 70 and can be removed only by an address from both Houses of Parliament for proved misbehaviour or incapacity. Their remuneration cannot be diminished while they are in office. State and territory judges have parallel protections under state constitutions or statute. The Judicial Conference of Australia and state judicial commissions handle complaints about judicial conduct, with serious matters referred to Parliament. Court budgets are set by Parliament rather than the executive department of the day, and judges' salaries are fixed by the Remuneration Tribunal at federal level.

The institution depends on specific operational tools. Judicial review of executive decisions is available under the Administrative Decisions (Judicial Review) Act 1977 and under section 75(v) of the Constitution, which lets the High Court issue writs of mandamus, prohibition, and injunction against Commonwealth officers. Contempt of court and sub judice rules protect ongoing proceedings from outside interference. Statutory interpretation principles, codified in the Acts Interpretation Act 1901, guide how courts read legislation. Legal aid commissions, Aboriginal Legal Services, and duty lawyers at every Magistrates' Court ensure that the institutional system remains accessible to people who cannot afford private representation.
