LAWS8213 Chap.2 The Australian Legal System
The Australian Legal System
This chapter turns the Australian legal system into a research map. It distinguishes the functions of Parliament, the executive and courts, asks where public power comes from, and shows how constitutional text, legislation, administration and judicial review interact. It also cautions against treating Indigenous laws and customs only through the lens of state recognition, because the legal question must be framed with care.

The Australian Legal System FAQ
Does separation of powers mean the branches never interact?
No broad answer should be given without identifying the branch relationship and constitutional setting. Functions and institutions can interact while legal boundaries still matter. Research the relevant constitutional text and cases, then explain the particular constraint rather than claiming complete practical separation.
Can the Commonwealth Parliament legislate on any topic?
The research begins by identifying a constitutional basis for the proposed Commonwealth law and any applicable prohibition or structural limit. Political importance does not itself supply legal competence. State legislation and the allocation of authority may also matter depending on the question.
How should Indigenous laws and customs be discussed?
Specify whether the question concerns continuing authority within community, recognition by legislation or courts, interaction with land rights, or another legal relationship. Avoid collapsing the existence and legitimacy of First Nations law into the narrower question of whether Australian state law recognises it in a particular setting.
Why should institutional verbs be precise?
Words such as enacts, administers, decides, interprets and reviews signal the legal role of the actor. Saying only that government made a rule can hide whether the relevant act was legislation, delegated rule-making or an administrative decision. Precise verbs lead to the correct instrument, authority test and review pathway.
They also prevent a paragraph from attributing a judicial interpretation to Parliament or treating an agency policy as though it were enacted law.
Assessment move
Draw the three branches as actors and add the legal verbs each performs. Beside Parliament, write enacts; beside the executive, administers and decides; beside courts, interprets and reviews. For each tutorial problem, identify the actor, action, empowering source, conditions, review route and possible remedy.
Practise separating a competence question from a merits question: first ask whether the institution may act and under what conditions, then assess whether the action is wise or fair. Read one issue through both legislation and a case to see how common-law reasoning and enacted text interact.
When considering Indigenous laws and customs, write the precise legal relationship being examined instead of using a single hierarchy as the answer. In class, contribute by asking which institution or instrument carries the claimed power. That question often converts a general political discussion into a legal analysis. Build two mini research trails from the same public controversy.
In the first, begin with the constitutional or statutory source of power. In the second, begin with a judgment reviewing the exercise of that power. Mark where the trails converge and what each route reveals sooner. Next, rewrite vague statements containing the word government by substituting the exact Parliament, minister, department, agency or court. For every substitution, attach the instrument and legal verb.
This practice makes later case notes more accurate because it prevents institutional background from being compressed into a misleading actor. Finish by stating one mechanism through which the institutional arrangement supports or limits a rule of law value.
