The role of juries (SACE Stage 2 Legal Studies)

What this dot point is asking

You must explain what juries do, where they are used, and evaluate their strengths and weaknesses.

What a jury does

In a jury trial there is a division of roles. The judge decides questions of law and directs the jury, and the jury decides questions of fact and delivers the verdict.

• In a criminal trial, the jury decides whether the prosecution has proved guilt beyond reasonable doubt. A criminal jury is usually made up of twelve people.
• In a civil trial, where a jury is used, it decides whether the defendant is liable on the balance of probabilities and may help assess damages, though civil juries are now rare.

Where juries are used

Juries are used mainly in serious criminal trials for indictable offences in the higher courts. Most criminal matters are dealt with summarily by a magistrate sitting alone, so juries decide only a small fraction of cases. The right to trial by jury for indictable Commonwealth offences is protected by section 80 of the Constitution.

Strengths of trial by jury

• Community participation brings everyday standards and values into the trial.
• Independence from the government and the judiciary protects against state power and bias.
• Spreading responsibility across twelve people reduces the influence of any single person's prejudice.
• Public confidence, because verdicts reached by ordinary citizens can be seen as fair and legitimate.

Weaknesses of trial by jury

• Complexity, because jurors may struggle with technical evidence or lengthy trials.
• No reasons given, so a jury verdict cannot be examined for the reasoning behind it.
• Possible bias or prejudice, despite directions from the judge.
• Cost and delay, because jury trials take longer and require selection and management.

Reform debates

Because of these weaknesses, there are ongoing debates about jury reform, such as allowing majority verdicts in some cases, giving juries better assistance with complex evidence, or removing juries from very long or technical trials. These debates connect to the wider tension between fairness and efficiency in the justice system.

The jury and community confidence

A central justification for the jury is that it brings the values and judgement of the community into the courtroom, so that serious decisions about guilt are made by ordinary citizens rather than by the state alone. This is said to legitimise verdicts, since the public is more likely to accept an outcome decided by a representative panel of peers. Supporters also argue that the requirement to persuade twelve lay people keeps the law and the lawyers comprehensible, and that the secrecy of deliberations protects jurors from pressure. Critics respond that juries can be swayed by emotion or skilled advocacy, may struggle with complex or technical evidence, and give no reasons, so an error cannot be identified or explained. Weighing community confidence against these reliability concerns is the heart of any evaluation of the jury system.

Connection to the rest of the course

The jury connects to the adversarial system, the criminal and civil divide, the court hierarchy and access to justice. It is also linked to the express constitutional right to trial by jury under section 80, tying Topic 4 back to constitutional government.
