(1) Grounds for New Trial. The court may, on motion, grant a new trial on all or some of the issues–and to any party–on any of the following grounds materially affecting that party’s rights:
(A) any irregularity in the proceedings or abuse of discretion depriving the party of a fair trial;
(B) misconduct of the jury or prevailing party;
(C) accident or surprise that could not reasonably have been prevented;
(D) newly discovered material evidence that could not have been discovered and produced at the trial with reasonable diligence;
(E) excessive or insufficient damages;
(F) error in the admission or rejection of evidence, error in giving or refusing jury instructions, or other errors of law at the trial or during the action;
(G) the verdict is the result of passion or prejudice; or
(H) the verdict, decision, findings of fact, or judgment is not supported by the evidence or is contrary to law.
(2) Further Action After a Nonjury Trial. After a nonjury trial, the court may, on motion for a new trial, vacate the judgment if one has been entered, take additional testimony, amend findings of fact and conclusions of law or make new ones, and direct the entry of a new judgment.
(b) Time to File a Motion; Response and Reply.
(1) Motion. A motion for a new trial, along with any supporting affidavits, must be filed no later than 15 days after the entry of judgment. This deadline may not be extended by stipulation or court order, except as allowed by Rule 6(b)(2). The motion may be amended at any time before the court rules on it.
(2) Response and Reply. Rule 7.1(a) governs responses and replies to a motion for new trial.
(c) New Trial on the Court’s Initiative or for Reasons Not in the Motion. No later than 15 days after the entry of judgment–which time may not be extended except as allowed by Rule 6(b)(2)–the court, on its own, may order a new trial for any reason set forth in Rule 59(a). After giving the parties notice and an opportunity to be heard, the court may grant a timely motion for a new trial for a reason not stated in the motion. In either event, the court must specify the reasons in its order.
(d) Motion to Alter or Amend a Judgment. A motion to alter or amend a judgment must be filed no later than 15 days after the entry of judgment. This deadline may not be extended by stipulation or court order, except as allowed by Rule 6(b)(2).
(e) Scope of New Trial. A new trial, if granted, must be limited to the question or questions found to be in error, if separable. If a new trial is ordered solely because the damages are excessive or inadequate and if the issue of damages is separable from all other issues in the action, the verdict may be set aside only on damages, and must stand in all other respects.
(f) Motion on Ground of Excessive or Inadequate Damages.
(1) Conditional Grant of New Trial.
(A) Generally. When a motion for new trial is based on the ground that the awarded damages are either excessive or insufficient, the court may grant the new trial conditionally if, within the time set by the court, the party adversely affected by the reduction or increase in damages files a statement accepting the amount of damages as designated by the court.
(B) Effect on Grant or Denial of New Trial. If the party adversely affected by the reduction or increase in damages files a statement as provided in Rule 59(f)(1)(A), the motion for new trial is deemed denied as of the date the statement is filed. If the party adversely affected does not file a statement, the motion for new trial is deemed granted as of the deadline specified by the court for filing the statement. No further written order is required to make an order granting or denying the new trial final. If the court’s conditional order requires a reduction of or increase in damages, then the new trial may be granted only on damages, and the verdict must stand in all other respects.
(2) Effect on Appeal. If a statement of acceptance is filed by the party adversely affected by reduction or increase of damages, and the other party later files an appeal, the party filing such statement may cross-appeal and, at its election, seek review of the superior court’s ruling that the awarded damages are either excessive or insufficient. If the court’s ruling on damages is affirmed, the party’s prior acceptance will remain in effect, unless the appeal’s final disposition requires otherwise.
(g) Motion for New Trial After Service by Publication.
(1) Generally. When judgment has been rendered on service by publication, and the defendant has not appeared, the court may grant a new trial if the defendant–within one year after entry of judgment–files an application establishing good cause for a new trial.
(2) Bond Required to Stay Execution. Execution of judgment should not be stayed unless the defendant posts a bond in double the amount of the judgment or the value of the property that is the subject of the judgment. The bond must be conditioned on the defendant’s prosecution of the application for new trial and on satisfaction of the judgment in full should the court deny the application.
(h) Number of New Trials. No more than two new trials may be granted to a party in the same action, except on the grounds of jury misconduct or errors of law.
(i) Order Must Specify Grounds. Any order granting a new trial or altering or amending a judgment must specify with particularity the ground or grounds for the court’s order.
