What Is the Role of a Jury in a Criminal Case?

Juries are a key part of the legal system. The founding fathers wanted to prevent the United States of America from developing an oppressive government. That is why the Bill of Rights includes the right against unreasonable searches and seizures, the right against self-incrimination, and the right to a trial by jury. These rights limit the power of the government over the people. 

There will be a jury in some civil cases, but the majority of jury trials are criminal trials. It's smart to understand how juries work in a criminal case. It's also wise to get legal representation from a defense lawyer when preparing for court.

The Right to a Jury Trial

It took the United States a while to recognize the right to a jury in all criminal cases, state or federal, felony or misdemeanor. The present state of criminal law is that the Sixth Amendment of the U.S. Constitution guarantees a jury trial to anyone facing a potential penalty of at least six months imprisonment. Also, in most states, the right to a trial by jury is not afforded to minors in juvenile delinquency proceedings.

How Grand Juries and Trial Juries Differ

It is important to note the difference between a grand jury and a trial jury. A grand jury decides whether charges should be brought against a suspect at the beginning of a case. If a grand jury finds that there is enough evidence to support these charges, there will be an arraignment. A trial jury hears the trial of the charges against the defendant in open court and decides whether the defendant is guilty or not guilty.

The Jury's Function

Jury service is a civic obligation and is required by every citizen of the United States. However, a jury alone doesn't guarantee a fair and impartial trial. The Constitution guarantees that members of the jury reflect one's "peers." The courts have further interpreted this to mean a fair cross-section of one's community.

Avoiding Bias in a Jury Trial

Whether it's a criminal case or a civil case, jury selection occurs pretrial in a process called "voir dire." This is when attorneys and the judge may ask the potential jurors questions to ensure their ability to serve and remain impartial in a given case. Although attorneys are allowed to reject prospective jurors using peremptory challenges, they're not allowed to shape the jury panel in a way that may appear to be biased toward a certain race, age, or gender. The attorneys will also set aside alternate jurors in case a selected juror falls ill or cannot make the trial for some other reason.

Hearing Details of the Case

During the trial, the jury will hear each side's opening statements, the facts of the case, the prosecution's evidence, and the defendant's potential defenses. One of the most influential parts of a trial is cross-examination. This is when the prosecution and the defense attempt to undermine the credibility of each party's witnesses.

Deciding the Outcome of the Criminal Trial

The jury will then weigh the evidence during jury deliberations. It is the jury's responsibility to determine whether the evidence satisfies the charged criminal offenses beyond a reasonable doubt.

At the end of the trial, after the attorneys' closing arguments and the judge's jury instructions, the jury will leave the courtroom to begin jury deliberations in the jury room. The jury's duty is to gather to discuss the evidence. Once the necessary consensus is reached, the jury will render the jury verdict of guilty or not guilty in a given case. In some jurisdictions, the judge will appoint a foreperson of the jury. A foreperson acts as the spokesperson for the jury.

Reaching a Unanimous Decision

In a unanimous decision, all jurors agree to the same outcome. Whether the jury has to reach a unanimous decision depends on whether the case is in federal court or state court.

It also depends on whether the case is a criminal or civil trial. In criminal court, nearly all states require the jury to return a unanimous verdict.

Benefits of a Jury Trial

A primary strength of the jury trial is that it acts as a check to unfettered prosecutorial power. Prosecutors have a tremendous amount of power when deciding whether to charge a defendant with a crime.

However, prosecutors understand that another group of people, whom they don't know, will be deciding their case after they present the evidence. Prosecutors typically don't want to waste time and resources on unreasonable charges in front of a jury.

Another strength of juries is that if judges decided every case, it could raise many concerns about fairness in the judicial process. For example, appointed judges might be beholden to politics and the people who appointed them. Additionally, elected judges could be swayed by public opinion in a given case.

Jurors, on the other hand, aren't appointed and serve on a jury as part of their civic duties. In cases where public opinion weighs heavily on one side, they can also be sequestered to minimize the amount of influence exerted by the public or media on a given matter.

Limitations of a Jury Trial

Jurors are laypeople who are sometimes asked to understand complicated legal concepts and apply those concepts to the case at hand. This is not an easy task and can be very time-consuming. Because of both the time and complexity of some matters, it's not surprising to hear stories about jurors falling asleep or failing to pay attention throughout a trial.

If the jury unanimously agrees on the guilt of a defendant, the case is usually returned to the judge for sentencing. If the jury can't agree, they usually get an "Allen" charge to try again. An Allen charge is a specific type of jury instruction regarding their duty to continue to deliberate. A case can also end in a mistrial. In this case, the prosecutor can try the case again or decide not to proceed a second time.

If a party is not satisfied with the jury's verdict and feels that the jury did not rely on the rules of evidence to make its decision, it can appeal the decision to the appellate court and beyond, perhaps even reaching the Supreme Court. A party can also appeal if it feels that the trial judge did not instruct the jury appropriately.
