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 Washington State, a motion for a new trial is governed by the Washington Rules of Civil Procedure (CR) 59. This rule allows a party to request a new trial on various grounds, including but not limited to, errors of law occurring at the trial, misconduct of the jury or prevailing party, newly discovered evidence that could not have been obtained with reasonable diligence before or during the trial, or an excessive or inadequate damages award that appears to have been influenced by passion or prejudice. The motion must be filed within 10 days after the entry of the judgment, unless the court allows a longer period. The trial court has discretion to grant or deny the motion, and its decision can be appealed. If the motion is granted, the court can order a new trial on all or some of the issues that were part of the original trial. The purpose of this procedure is to ensure that a party receives a fair trial and to correct any significant errors that may have affected the trial's outcome.
