Key Concepts

Purpose of laws

Laws establish clear, enforceable rules that protect rights, maintain social order and guide behaviour. They help prevent harm, resolve conflict and support the principles of justice — equality, fairness and access.

Sources of law

Australia’s laws come from three main sources:

• Statute law, created by Parliament through the legislative process

• Common law, developed by courts through judicial decisions and the doctrine of precedent

• Delegated legislation, made by authorised bodies such as government departments, local councils and regulators under powers granted by Parliament

Ways to classify the law

Laws can be classified as criminal or civil, public or private, common or statute, and domestic or international. These classifications help explain how different legal processes operate and how disputes are resolved.

Law‑making processes

Parliaments debate, amend and pass bills to create statute law, while courts interpret legislation and develop legal principles through case law. Delegated legislation allows specialised bodies to make rules under authority granted by Parliament.

Rule of law

The rule of law requires that laws are clear, known, applied equally and enforced fairly. It prevents arbitrary power and ensures governments, institutions and individuals are accountable under the law.

Rights and responsibilities

Laws outline the rights individuals hold and the responsibilities they owe to others and the community. These rights and responsibilities are defined in the law and are protected by a patchwork of different mechanisms.

Enforcement

Police, regulators and courts ensure laws are followed, and respond when they are breached. Legal institutions apply the burden and standard of proof to determine responsibility and deliver appropriate remedies or penalties.

Legal certainty

People must be able to understand the law so they can plan their actions and know the consequences. Clear, accessible laws support confidence in the legal system.

Accountability

Governments, public officials, businesses, and private individuals are subject to the law. Courts, tribunals and review bodies help ensure decisions are lawful and that misuse of power can be challenged.
