The Judiciary (sometimes called the courts) makes judgements about the law. The Judiciary is made up of the High Court of Australia and other federal courts.
The Australian Constitution divides the power to make and manage laws between 3 largely separate groups. This division is based on the principle of the separation of powers. The 3 groups that share the power to make and manage federal law are the Parliament, the Executive and the Judiciary
