(1)    Motion at close of plaintiff‘s evidence. After the plaintiff, in an action tried by the court without a jury, has completed the presentation of his or her evidence, the defendant, without waiving his or her right to offer evidence in the event the motion is not granted, may move for a dismissal on the ground that upon the facts and the law the plaintiff has shown no right to relief. The court as trier of the facts may then determine them and render judgment against the plaintiff on that ground or may decline to render any judgment until the close of all the evidence. If the court renders judgment on the merits against the plaintiff, the court shall make findings as provided in sub. (2). Unless the court in its order for dismissal otherwise specifies, a dismissal under this section operates as an adjudication upon the merits.

   (2)   Effect. In all actions tried upon the facts without a jury or with an advisory jury, the court shall find the ultimate facts and state separately its conclusions of law thereon. The court shall either file its findings and conclusions prior to or concurrent with rendering judgment, state them orally on the record following the close of evidence or set them forth in an opinion or memorandum of decision filed by the court. In granting or refusing interlocutory injunctions the court shall similarly set forth the findings of fact and conclusions of law which constitute the grounds of its action. Requests for findings are not necessary for purposes of review. Findings of fact shall not be set aside unless clearly erroneous, and due regard shall be given to the opportunity of the trial court to judge the credibility of the witnesses. The findings of a referee may be adopted in whole or part as the findings of the court. If an opinion or memorandum of decision is filed, it will be sufficient if the findings of ultimate fact and conclusions of law appear therein. If the court directs a party to submit proposed findings and conclusions, the party shall serve the proposed findings and conclusions on all other parties not later than the time of submission to the court. The findings and conclusions or memorandum of decision shall be made as soon as practicable and in no event more than 60 days after the cause has been submitted in final form.

   (3)   Reconsideration motions. Upon its own motion or the motion of a party made not later than 20 days after entry of judgment, the court may amend its findings or conclusions or make additional findings or conclusions and may amend the judgment accordingly. The motion may be made with a motion for a new trial. If the court amends the judgment, the time for initiating an appeal commences upon entry of the amended judgment. If the court denies a motion filed under this subsection, the time for initiating an appeal from the judgment commences when the court denies the motion on the record or when an order denying the motion is entered, whichever occurs first. If within 90 days after entry of judgment the court does not decide a motion filed under this subsection on the record or the judge, or the clerk at the judge’s written direction, does not sign an order denying the motion, the motion is considered denied and the time for initiating an appeal from the judgment commences 90 days after entry of judgment.

   (4)   Appeal. In actions tried by the court without a jury, the question of the sufficiency of the evidence to support the findings may be raised on appeal whether or not the party raising the question has objected in the trial court to such findings or moved for new trial.
