Rule 41 - Dismissal of Actions(a) Voluntary dismissal; effect thereof.(1) By plaintiff; by stipulation. An action may be dismissed by the plaintiff without order of court (I) except in replevin, by filing a notice of dismissal at any time before service by the adverse party of an answer or of a motion for summary judgment whichever first occurs or (II) by filing a stipulation of dismissal signed by all the parties who have appeared in the action. Unless otherwise stated in the notice of dismissal or stipulation, the dismissal is without prejudice, except that a notice of dismissal operates as an adjudication upon the merits when filed by a plaintiff who has once dismissed in any court of the United States or of any state an action based on or including the same claim.(2) By order of Court. Except as provided in paragraph (1) of this subdivision of this Rule, an action shall not be dismissed at the plaintiff's instance save upon order of the Court and upon such terms and conditions as the Court deems proper. If a counterclaim has been pleaded by a defendant prior to the service upon defendant of the plaintiff's motion to dismiss, the action shall not be dismissed against the defendant's objection unless the counterclaim can remain pending for independent adjudication by the Court. Unless otherwise specified in the order, a dismissal under this paragraph is without prejudice.(b) Involuntary dismissal; effect thereof. For failure of the plaintiff to prosecute or to comply with these Rules or any order of Court, a defendant may move for dismissal of an action or of any claim against the defendant. After the plaintiff, in an action tried by the Court without a jury, has completed the presentation of plaintiff's 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. The Court as trier of the facts may then determine them and render judgment against the plaintiff or may decline to render any judgment until the close of all the evidence. Unless the Court in its order for dismissal otherwise specifies, a dismissal under this subdivision and any dismissal not provided for in this Rule, other than a dismissal for lack of jurisdiction, for improper venue, or for failure to join a party under Rule 19, operates as an adjudication upon the merits.(c) Dismissal of counterclaim, cross-claim or third-party claim. The provisions of this Rule apply to the dismissal of any counterclaim, cross-claim, or third-party claim. A voluntary dismissal by the claimant alone pursuant to paragraph (1) of subdivision (a) of this Rule shall be made before a responsive pleading is served or, if there is none, before the introduction of evidence at the trial or hearing.(d) Costs of previously dismissed action. If a plaintiff who has once dismissed an action in any court commences an action based upon or including the same claim against the same defendant, the Court may make such order for the payment of costs of the action previously dismissed as it may deem proper and may stay the proceedings in the action until the plaintiff has complied with the order.(e) Dismissal for failure to prosecute. The Court may order an action dismissed, sua sponte, upon notice of the Court, for failure of a party diligently to prosecute the action, for failure to comply with any rule, statute, or order of the Court, or for any other reason deemed by the Court to be appropriate. In the event that the Court shall conclude, sua sponte, that dismissal upon any of foregoing grounds appears appropriate, the procedure for such dismissal shall be as follows: The Clerk shall forward to the party a notice directing that the party show cause why the action should not be dismissed for the reasons stated in the notice. The notice shall direct the party to respond within 10 days after receipt of the notice. After consideration of such response, the Court shall enter an order dismissing the action or maintaining jurisdiction of the case. If a response is not filed within the time allowed, the dismissal shall be deemed to be unopposed. If the Court is satisfied that the action should be dismissed, it shall enter an order of dismissal. Upon entry of any order of dismissal, the Court shall specify the terms thereof including provision for payment of costs. In the case of any action which has been pending in this Court for more than six months without any proceedings having been taken therein during that six month period, the Clerk of the Court shall, after the expiration of the period, mail to the parties a notice notifying them that the action will be dismissed by the Court for want of prosecution if no proceedings are taken therein within 30 days. If no proceedings are taken in the action within a period of 30 days after the mailing of such notice, it shall thereupon be dismissed by the Court as of course for want of prosecution. Such actions may also be dismissed for want of prosecution at any time by motion of any party.(f) Without prior notice. The Court may order a complaint, petition or appeal dismissed, sua sponte, without notice, notwithstanding the provisions of Rule 41(e), when such complaint, petition or appeal manifestly fails on its face to invoke the jurisdiction of the Court and where the Court concludes, in the exercise of its discretion, that the giving of notice would serve no meaningful purpose and that any response would be of no avail.
