Court Hierarchy and Adversarial System - TCE Legal Studies (Tasmania)
“Explain the structure of the court hierarchy and the features of the adversarial system of trial.”
Courts are ranked in a hierarchy from lower to higher courts, which supports appeals and the doctrine of precedent. In the adversarial system, two opposing parties argue their cases before an impartial judge who acts as a neutral umpire.
What this dot point is asking
This dot point has two linked parts: the way courts are ranked, and the way trials are run.
The court hierarchy is the ranking of courts from lowest to highest. In Tasmania the main courts are the Magistrates Court (which hears minor criminal matters and smaller civil claims) and the Supreme Court of Tasmania (which hears serious criminal cases such as murder, larger civil disputes, and appeals from the Magistrates Court). Appeals from the Supreme Court can go to the Full Court of the Supreme Court of Tasmania, also called the Court of Criminal Appeal in criminal matters. At the national level sit the federal courts, including the Federal Court of Australia and the Federal Circuit and Family Court of Australia. At the very top is the High Court of Australia, the final court of appeal for the whole country and the court that interprets the Constitution.
A hierarchy exists for several reasons. It allows specialisation, so minor matters are dealt with quickly in lower courts while serious matters go to higher courts. It enables a system of appeals, so a party who believes a court made an error can ask a higher court to review the decision. It also makes the doctrine of precedent work.
Precedent (stare decisis, meaning to stand by what is decided) is the rule that decisions of higher courts bind lower courts in the same hierarchy on similar facts. The binding part of a decision is the ratio decidendi (the legal reasoning for the outcome). Comments not essential to the decision are obiter dicta and are persuasive only.
Precedent depends on the hierarchy. A decision of the High Court binds all Australian courts below it. A Supreme Court of Tasmania decision binds the Tasmanian Magistrates Court. Courts can sometimes distinguish a precedent if the facts are materially different, and higher courts can overrule earlier decisions. This gives the law both consistency and the ability to develop.
The adversarial system is the method Australia uses to conduct trials. Its main features are:
- Two opposing sides (the parties) each present their own case. In a criminal trial this is the prosecution against the accused; in a civil trial it is the plaintiff against the defendant.
- The judge (or magistrate) acts as an impartial umpire who controls the trial, rules on law and procedure, and does not investigate or take sides.
- The parties, usually through lawyers, decide what evidence to call and which witnesses to question, including cross-examination of the other side's witnesses.
- Strict rules of evidence and procedure govern what can be presented and how.
- The burden of proof falls on the party bringing the case. In criminal trials the prosecution must prove guilt beyond reasonable doubt; in civil trials the plaintiff must prove the claim on the balance of probabilities.
Criminal cases require proof beyond reasonable doubt, a high standard because a person's liberty is at stake. Civil cases use the lower balance of probabilities, meaning more likely than not.
The adversarial system is often contrasted with the inquisitorial system used in many European countries, where the judge actively investigates the facts and questions witnesses. Strengths of the adversarial approach include the impartiality of the decision-maker and the chance for each side to fully test the other's evidence. Criticisms include cost, delay, and the advantage that a well-resourced party with better lawyers may hold.
A common task asks you to link the hierarchy to the doctrine of precedent. Work through it in steps.
Step 1: Sketch the hierarchy
Set out the Tasmanian courts from the Magistrates Court up to the Supreme Court and its Full Court, then the federal courts and the High Court of Australia at the top.
Step 2: Give the reasons for the hierarchy
Explain that the ranking allows specialisation, enables appeals to a higher court, and makes precedent work.
Step 3: Explain precedent
State that decisions of higher courts bind lower courts in the same hierarchy on similar facts; the binding part is the ratio decidendi, while obiter dicta are persuasive only.
Step 4: Show the link
Conclude that precedent depends on the hierarchy: a High Court decision binds all courts below it, giving the law both consistency and the ability to develop through distinguishing and overruling.
Students sometimes mix up the hierarchy and the adversarial system. The hierarchy is about which courts rank above others and how appeals and precedent flow. The adversarial system is about how a single trial is run. Keep the two concepts separate in your answer.
In exam responses, sketch the hierarchy from Magistrates Court up to the High Court, link it to appeals and precedent, then describe the adversarial trial features and the two standards of proof.
Exam-style questions
Questions in the style of TASC exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
Practice6 marksExplain why courts are organised in a hierarchy.Show worked answer →
A 6 mark response needs the main reasons a hierarchy exists.
Specialisation. Minor matters are dealt with quickly and cheaply in lower courts (the Magistrates Court), while serious matters go to higher courts (the Supreme Court).
Appeals. A party who believes a court erred can ask a higher court to review the decision, which helps correct mistakes.
Precedent. The hierarchy makes the doctrine of precedent work, because decisions of higher courts bind lower courts in the same hierarchy.
Markers reward the three reasons (specialisation, appeals, precedent) explained clearly, ideally naming the Tasmanian courts.
Practice12 marksDescribe the main features of the adversarial system and evaluate its strengths and weaknesses.Show worked answer →
A 12 mark evaluation needs the features, then a balanced assessment with a judgement.
Features. Two opposing parties present their own cases; the judge or magistrate is an impartial umpire who controls law and procedure but does not investigate; the parties decide what evidence and witnesses to call and may cross-examine; strict rules of evidence apply; the party bringing the case bears the burden of proof.
Strengths. The decision-maker is impartial, each side can fully test the other's evidence, and parties control their own case.
Weaknesses. It can be costly and slow, and a well-resourced party with better lawyers may have an advantage; it is sometimes contrasted with the inquisitorial system, where the judge investigates.
Judgement. Conclude with a defended position, for example that the adversarial system protects fairness through impartiality and testing of evidence but raises real concerns about cost and inequality of resources. Markers reward a balanced evaluation reaching a conclusion.
