The judge is like an umpire in a game and conducts the trial impartially and in an open court. The judge hears all the witnesses and any other evidence presented by the prosecution and the defense. The judge decides whether the accused person is guilty or innocent on the basis of the evidence presented and in accordance with the law. If the accused is convicted, then the judge pronounces the sentence. He may send the person to jail or impose a fine or both, depending on what the law prescribes.
