(a) Motion for Directed Verdict: When Made: Effect. A party may move for a directed verdict at the close of the evidence offered by an opponent. The filing of such motion does not constitute a waiver of movant’s right to offer evidence to the same extent as if the motion had not been made. A motion which is not granted is not a waiver of trial by jury even though all parties to the action have moved for directed verdicts. A motion for a directed verdict shall state the specific grounds therefor. The order of the court granting a motion for a directed verdict is effective without any assent of the jury.(b) Motion for Judgment Notwithstanding the Verdict. A party may move for a directed verdict at the close of all the evidence. Whenever such motion is denied or for any reason is not granted, the court is deemed to have submitted the action to the jury subject to a later determination of the legal questions raised by the motion. Not later than thirty days after entry of judgment, a party who has moved for a directed verdict may move to have the verdict and any judgment entered thereon set aside and to have judgment entered in accordance with the motion for a directed verdict; or if a verdict was not returned, such party, within thirty days after the jury has been discharged, may move for judgment in accordance with the motion for a directed verdict. A motion for a new trial may be joined with this motion, or a new trial may be prayed for in the alternative. If a verdict was returned the court may allow the judgment to stand or may reopen the judgment and either order a new trial or direct the entry of judgment as if the requested verdict had been directed. If no verdict was returned the court may direct the entry of judgment as if the requested verdict had been directed or may order a new trial.(c) Same: Conditional Rulings on Grant of Motion.(1) If the motion for judgment notwithstanding the verdict provided for in subdivision (b) of this Rule, is granted, the court shall also rule on the motion for a new trial, if any, by determining whether it should be granted if the judgment is thereafter vacated or reversed, and shall specify the grounds for granting or denying the motion for the new trial. If the motion for a new trial is thus conditionally granted, the order thereon does not affect the finality of the judgment. In case the motion for a new trial has been conditionally granted and the judgment is reversed on appeal, the new trial shall proceed unless the appellate court has otherwise ordered. In case the motion for new trial has been conditionally denied, the respondent on appeal may assert error in that denial; and if the judgment is reversed on appeal, subsequent proceedings shall be in accordance with the order of the appellate court.(2) The party whose judgment has been set aside on the motion for judgment notwithstanding verdict, may upon appeal from the resulting adverse judgment, in addition to urging that the trial court erred in sustaining the motion for judgment notwithstanding the verdict, also brief and argue and the appellate court may determine, whether the appellant is, in any event, entitled to a new trial.(d) Same: Denial of Motion. If the motion for judgment notwithstanding the verdict is denied, the party who prevailed on that motion, as respondent, may assert grounds entitling the party to a new trial in the event the appellate court concludes that the trial court erred in denying the motion for judgment notwithstanding the verdict. If the appellate court reverses the judgment, nothing in this Rule 72.01 precludes it from determining that the respondent is entitled to a new trial or from directing the court to determine whether a new trial shall be granted.
