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 Minnesota, a motion for a new trial is governed by the Minnesota Rules of Civil Procedure, Rule 59. This rule allows a party to request a new trial on all or some of the issues for reasons including, but not limited to, irregularity in the proceedings, misconduct by the jury or prevailing party, accidents or surprise that could not have been prevented by ordinary prudence, newly discovered evidence that could not have been discovered and produced at trial with reasonable diligence, excessive or insufficient damages, error in law occurring at the trial and objected to by the party making the motion, or the verdict is not justified by the evidence or is contrary to law. The motion must generally be served and filed within 28 days after the entry of judgment. The court then considers whether there were significant errors in the trial that prevented a fair trial, and if so, may grant a new trial. The decision to grant a new trial is at the discretion of the trial court and is subject to review on appeal.
