What are the differences in the roles played by a Judge and a Jury in a Court Room?

What is a Judge?

A judge is a person, either a man or a woman, who presides over a court of law. Most judges preside alone, but sometimes preside as part of a panel of judges or other legal professionals.  A judge typically presides over a physical court room facility, but sometimes conducts court via two-way video in cases where safety is a concern or to expedite the judicial process. The powers, functions, method of appointment, discipline, and training of judges vary widely across different jurisdictions. Check local laws and statutes if doing research for a case.

The judge hears all the witnesses and any other evidence presented by both of the parties of the legal case, commonly referred to as the Plaintiff and Defendant.

The judge assesses the credibility of the parties involved in the case, and then issues an official ruling or decision based on his or her interpretation of the law and his or her own personal judgment.

In some jurisdictions, powers may be shared with a jury, although this practice is starting to be phased out in some regions.

In many states throughout the United States, a judge is addressed verbally as “Your Honor” or “Judge” when presiding over the court. “Judge” may be more commonly used by attorneys and staff, while either may be commonly used by the plaintiff or defendant in the court room. In some situations, you may hear the term “Justice of the Peace” or “magistrate”.

Private detectives and police officers may have to stand before a judge when involved in legal proceedings.

Juries: Determining Guilt or Innocence in a Legal Court Case

A jury, which is sometimes referred to as a court jury, is a sworn body of people convened to render an impartial verdict (which is basically the finding of fact on a legal-related question) officially submitted to them by a court, or to set a penalty or judgment in a court case.

The word jury is derived from the French word “jure”, which means “sworn”.  They are found in both criminal cases and civil lawsuits to ascertain the guilt or innocence in a crime. The verdict, or decision, in any particular court case may be guilty or not guilty.

Juries are an essential part of the legal process. In today’s world, the judges act as triers of law while the juries act as a triers of fact. The bench trial is the trial without the jury.

Potential jurors are selected by legal counsel (lawyers and attorneys) from what is known as a jury pool. The pool is created from citizens who are chosen at random in the local jurisdiction.

Those chosen, listen and observe as the court case that is presented by the legal counsel of the plaintiff and the defendant. After both cases are presented, the members retire to a location outside of the court room to discuss the facts and determine a verdict. The majority opinion of the group determines the ultimate verdict in the court case.

Other Facts

  • The size varies depending on the type of court case
  • If the group is unable to reach a verdict, it is known as a hung jury
  • A bench trial is a trial without a jury
  • Juries are usually composed of jurors (also known as jurymen)

Different Types

  • Petit Jury– This type of group is used in either criminal cases or civil cases.
  • Grand Jury– This type is used in federal court cases. Grand juries review the evidence presented by the prosecutor and issue indictments if warranted. Grand juries normally consist of 12 jurors.
  • Coroner’s Jury– This type is formed to assist the coroner in detecting the reason(s) for a person’s death. A coroner is a public official that is elected by the local government to determine the reasons  and circumstances leading to the death of the person in suspicious cases. The coroner’s jury is formed to increase the confidence of the people for the investigation conducted by the coroner.
