(1) If the motion for judgment notwithstanding the verdict, provided for in Rule 50.02, 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 a new trial has been conditionally denied, the appellee 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 verdict has been set aside on motion for judgment notwithstanding the verdict may serve a motion for a new trial pursuant to Rule 59 not later than 10 days after entry of the judgment notwithstanding the verdict.

(3) If the motion for judgment notwithstanding the verdict is denied, the party who prevailed on that motion may, as appellee, assert grounds entitling him 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 Rule 50 precludes it from determining that the appellee is entitled to a new trial, or from directing the trial court to determine whether a new trial shall be granted.
