The Rules of Evidence are guidelines that determine what information can be presented in a legal proceeding. These rules help ensure that only relevant, reliable, and admissible evidence is considered by the court. They aim to protect the rights of individuals while promoting a fair trial. These rules cover various types of evidence, including witness testimony, documents, and physical evidence. They also address issues like hearsay, which is information not based on a witness's direct knowledge. Understanding these rules is essential for lawyers and judges to make informed decisions during a trial.
