Courts do not usually create law in the same deliberate, policy-based way as parliament. Their main role is to resolve disputes by applying law. However, court decisions can still develop the law through precedent and statutory interpretation.

Court hierarchy and precedent

Precedent means decisions of higher courts can bind lower courts in later cases with similar material facts. The binding part of a judgment is the ratio decidendi, meaning the legal reason for the decision. Comments made by the judge that are persuasive but not binding are obiter dicta.

Precedent supports consistency and predictability. Similar cases should be treated similarly. It also allows law to develop case by case as new disputes reach the courts.

The court hierarchy determines whether precedent is binding or persuasive. A decision of a higher court in the same hierarchy can bind a lower court. A decision from another hierarchy, a lower court, or another jurisdiction may still be persuasive if its reasoning is strong. Appeals matter because they allow legal errors to be corrected and allow higher courts to clarify principles for future cases.

Jurisdiction is the power of a court or tribunal to hear a matter. It can depend on subject area, geography, monetary limits, seriousness of offence or whether the matter is an appeal. Do not treat all courts as interchangeable; a constitutional dispute, a family law dispute and a minor civil claim belong in different parts of the system.

Statutory interpretation

Courts also influence law by interpreting legislation. If a statute uses unclear language, a court may decide what the words mean in context. That interpretation can affect future cases and show parliament where the statute needs reform.

Sometimes parliament responds by amending legislation. This creates a law-making conversation: courts interpret and identify problems, while parliament can confirm, change or override the legal position through legislation.

Specialist courts and tribunals

Specialist courts and tribunals deal with particular types of disputes. They may be faster, cheaper or more expert than general courts. Examples include tribunals dealing with civil and administrative matters, or specialist lists and courts focused on areas such as family, children, drug-related matters or domestic and family violence.

Their strengths include expertise, accessibility and flexible processes. Their weaknesses can include limited jurisdiction, resource pressure, delays and the fact that some decisions may still need review or appeal.

At the federal level, the Federal Court deals with many Commonwealth law matters, including administrative law, corporations, migration, intellectual property and some human rights-related disputes. The Federal Circuit and Family Court deals with family law and a wide range of federal matters. Tribunals are different from courts: they are usually designed to be less formal, but their powers depend strictly on the statute creating them.

Landmark cases

Landmark cases are useful because they show courts influencing legal meaning or reform. The Mabo decision is a classic example. It rejected terra nullius as a foundation for Australian land law and recognised native title under Australian common law, subject to conditions and later legislation.

The Wik decision is also important in native title discussions because it considered how native title could interact with pastoral leases. Together, cases like these show how courts can reshape legal understandings and trigger legislative responses.

Other cases are useful as examples of method rather than as names to memorise. *Donoghue v Stevenson* is the classic duty of care case and shows common law developing through a concrete dispute. *Dietrich v The Queen* is useful for fair trial discussions because it connects legal representation with trial fairness in serious criminal matters. *Roadshow Films v iiNet* is useful when discussing courts applying older legal categories to technology-related disputes. The point is not to list cases; it is to show how courts reason from facts, legal principles and precedent.

Strengths of courts as law-makers

Courts can protect individual rights in concrete disputes, develop legal principles carefully, and operate independently from immediate political pressure. They also give detailed reasons, which helps transparency and future legal development.

Weaknesses of courts as law-makers

Courts must wait for a suitable case. Litigation can be expensive and slow. Judges are unelected, so broad social reform through courts can raise democratic legitimacy concerns. Court decisions are also limited by the facts, arguments and legal issues before them.

How to use cases in analysis

A strong Legal Studies answer does not drop case names randomly. It uses cases to prove a legal point. For example, *Mabo v Queensland (No 2)* is useful when discussing how courts can develop common law and influence parliament. The decision rejected terra nullius, recognised native title at common law and created pressure for the Native Title Act 1993 (Cth). The case therefore works as an example of courts identifying a legal issue, while parliament then responds with broader legislation.

The Tasmanian Dam Case is useful for federalism and constitutional interpretation. It shows how the High Court's interpretation of a Commonwealth power can affect the balance between federal and state law-making. If a question asks about s 51, international obligations or residual powers, this case is usually more relevant than a native title case.

Wik is useful when explaining that legal change can create uncertainty. The High Court held that pastoral leases did not necessarily extinguish native title. That legal finding mattered, but the political and community reaction also mattered because parliament later amended native title legislation. In other words, courts can trigger reform, but they do not control every later policy choice.

When choosing a case, ask three questions: what legal rule did the case affect, which institution made the change, and what was the practical impact on stakeholders?
