A motion for new trial is a procedure that allows the trial court to order a new trial to correct significant errors in the previous trial that prevented a party from receiving a fair trial.
In Wisconsin, a motion for a new trial is governed by the Wisconsin Statutes and the Wisconsin Rules of Civil Procedure. According to Section 805.15 of the Wisconsin Statutes, a party may file a motion for a new trial on various grounds, including errors in the trial, newly discovered evidence, misconduct by the jury or parties, or if the verdict is against the great weight of the evidence. The motion must generally be filed within a specified time after the verdict or decision, usually within 20 days. The trial court has discretion to grant a new trial if it finds that a mistake was made that affected the party's rights and that a new trial would likely produce a different result. The purpose of this procedure is to ensure that all parties have received a fair trial and to correct any significant errors that may have occurred during the original proceedings.
