In law, a judicial examination of issues of fact or law for the purpose of determining the rights of the parties involved. Attorneys for the plaintiff and the defendant make opening statements to a judge or jury, then the attorney for the plaintiff makes his case by calling witnesses, whom the defense attorney may cross-examine. Unless the case is then dismissed for lack of sufficient evidence, the defense attorney next takes a turn calling witnesses, whom the plaintiff's attorney cross-examines. Both sides make closing arguments. In a trial before a jury, the judge instructs the jury on the applicable laws, and the jury retires to reach a verdict. If the defendant is found guilty, the judge then hands down a sentence.
