A jury trial is a legal proceeding where a group of people, known as a jury, listens to evidence and arguments presented by both sides in a case. The jury's role is to determine the facts and decide whether the accused is guilty or not guilty in criminal cases, or liable or not liable in civil cases. During a jury trial, the judge oversees the proceedings, ensuring that the law is followed. The jury's decision, called a verdict, is based on the evidence presented and must be unanimous in criminal cases in many jurisdictions, meaning all jurors must agree on the outcome.
