The Role of the Jury is to serve as a fact-finding body in a court of law. Juries are typically composed of twelve people who are randomly selected from the general population to hear evidence presented in a criminal or civil trial. The jury is responsible for determining the facts of the case, applying the law to those facts, and rendering a verdict. Juries typically play two main roles: first, they serve as triers of fact and make determinations regarding the credibility of the evidence; and second, they serve as a check on the power of the court and government by ensuring that the law is applied fairly and impartially. There are three types of Role of the Jury: 1. Grand Jury: A grand jury is responsible for deciding whether there is sufficient evidence to bring criminal charges against an individual. Grand juries are typically composed of 16-23 people who hear evidence presented by a prosecutor and decide whether there is enough evidence to issue an indictment. 2. Petite Jury: A petite jury, also known as a trial jury, is responsible for deciding the guilt or innocence of a defendant in a criminal trial. Petite's juries are typically composed of twelve people who hear evidence and arguments presented by both sides and then render a verdict. 3. Civil Jury: A civil jury is responsible for deciding the outcome of a civil trial. Civil juries are typically composed of six people who listen to the evidence and arguments presented by both sides and then render a verdict.
