(a) The court may upon its own initiative, or upon motion of a party, and upon such notice as it may prescribe, dismiss an action or claim for failure to prosecute or to comply with these rules or any order of the court.(b) After the plaintiff has completed the presentation of evidence, the defendant, without waiving the 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. In an action tried by the court without a jury, the court as trier of the fact may then determine the facts and render judgment against the plaintiff 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 Rule 52.01.(c) Unless the court specifies otherwise in its order, a dismissal pursuant to this rule and any dismissal not provided for in this rule or in Rule 41.01, other than a dismissal for lack of jurisdiction, for forum non conveniens, or for failure to join a party indispensable pursuant to Rule 19, operates as an adjudication upon the merits.
