The Australian Constitution divides the power to make and manage laws between three largely separate groups. This division is based on the principle of the 'separation of powers'. The three groups that share the power to make and manage federal law are the Parliament, the Executive and the Judiciary
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.
