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 Missouri, a motion for a new trial is governed by Missouri Rules of Civil Procedure, specifically Rule 78.04. This rule allows a party to file a motion for a new trial within 30 days after the entry of the judgment. The motion must specify the grounds for seeking a new trial, which typically include errors of law that occurred during the trial, newly discovered evidence, misconduct of the jury or a party, a verdict that is against the weight of the evidence, or other reasons that prevented the party from having a fair trial. If the trial court finds that significant errors or issues affected the trial's fairness or outcome, it has the discretion to grant a new trial. The decision to grant or deny a motion for a new trial is subject to review by appellate courts if further appealed.
