Lesson 7: The Role of Juries in Criminal Trials

This lesson explores the critical function that juries play in the criminal justice system, particularly in the context of criminal trials.

Introduction

The jury system is a fundamental component of the criminal procedure law. It provides an impartial body to render verdicts on matters of fact, thereby upholding the defendant's right to a fair trial.

Composition of a Jury

Typically, a jury in a criminal trial is composed of 12 citizens, although this number can vary depending on the jurisdiction and the specific case.

Jury Selection and Voir Dire

The process of selecting jurors is known as voir dire. During this stage, potential jurors are questioned by both the prosecution and the defense to uncover any biases.

Function of the Jury

The primary function of the jury is to evaluate the evidence presented during the trial and to render a verdict of 'guilty' or 'not guilty'.

Jury Deliberations

Once all the evidence is presented, the jury retires to deliberate in private. The jurors will discuss the case, review the evidence, and attempt to reach a unanimous decision.

Unanimity and Hung Juries

In most jurisdictions, the jury's decision must be unanimous. If the jury cannot reach a unanimous decision, it is considered a hung jury, and the judge may declare a mistrial.

Importance of Jury Trials

Jury trials are essential for maintaining public confidence in the criminal justice system. They ensure that community standards are reflected in verdicts and that the power to determine guilt or innocence is not concentrated in the hands of a single judge.

Conclusion

The role of the jury is pivotal in criminal trials, providing a means for ordinary citizens to participate in the administration of justice. This process helps to uphold the democratic principles upon which the legal system is founded.
