The trial process is a legal procedure where a case is presented before a judge and sometimes a jury. It typically begins with jury selection, followed by opening statements from both sides. The prosecution or plaintiff presents evidence and witnesses first, aiming to prove their case, while the defense has the opportunity to challenge this evidence and present their own. After both sides have presented their arguments, closing statements are made. The judge then instructs the jury on the law, and they deliberate to reach a verdict. If a jury is not involved, the judge will make the final decision. The outcome can lead to appeals if either party believes there was an error in the trial.
