Federal Rule of Civil Procedure 41
Rule 41. Dismissal of Actions
(1) By the Plaintiff.
(ii) a stipulation of dismissal signed by all parties who have appeared.
(B) Effect. Unless the notice or stipulation states otherwise, the dismissal is without prejudice. But if the plaintiff previously dismissed any federal or state-court action based on or including the same claim, a notice of dismissal operates as an adjudication on the merits.
(2) By Court Order; Effect. Except as provided in Rule 41(a)(1), an action may be dismissed at the plaintiff’s request only by court order, on terms that the court considers proper. If a defendant has pleaded a counterclaim before being served with the plaintiff’s motion to dismiss, the action may be dismissed over the defendant’s objection only if the counterclaim can remain pending for independent adjudication. Unless the order states otherwise, a dismissal under this paragraph (2) is without prejudice.
(b) INVOLUNTARY DISMISSAL; EFFECT. If the plaintiff fails to prosecute or to comply with these rules or a court order, a defendant may move to dismiss the action or any claim against it. Unless the dismissal order states otherwise, a dismissal under this subdivision (b) and any dismissal not under this rule—except one for lack of jurisdiction, improper venue, or failure to join a party under Rule 19—operates as an adjudication on the merits.
(c) DISMISSING A COUNTERCLAIM, CROSSCLAIM, OR THIRD-PARTY CLAIM. This rule applies to a dismissal of any counterclaim, crossclaim, or third-party claim. A claimant’s voluntary dismissal under Rule 41(a)(1)(A)(i) must be made:
(1) before a responsive pleading is served; or
(2) if there is no responsive pleading, before evidence is introduced at a hearing or trial.
(d) COSTS OF A PREVIOUSLY DISMISSED ACTION. If a plaintiff who previously dismissed an action in any court files an action based on or including the same claim against the same defendant, the court:
(1) may order the plaintiff to pay all or part of the costs of that previous action; and
(2) may stay the proceedings until the plaintiff has complied.
- A plaintiff may voluntarily dismiss her case pursuant to Rule 41. If a plaintiff fails to prosecute here case, the court can also involuntarily dismiss the case.
- When a defendant fails to defend a case a court can enter default judgment pursuant to Rule 55.
