Courtroom evidence refers to the information presented during a trial to support or refute claims made by either party. This evidence can include various types, such as witness testimony, documents, photographs, and physical objects. The goal is to establish facts that help the judge or jury make an informed decision about the case. In legal proceedings, evidence must be relevant, reliable, and admissible according to the rules of evidence. The judge determines what evidence can be presented, ensuring it meets legal standards. Properly collected and preserved evidence is crucial for maintaining the integrity of the judicial process.
