Rule 41(b) of the FRCP states:
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.
The following form is a complaint that adopts the "notice pleadings" format of the Federal Rules of Civil Procedure, which have been adopted by most states in one form or another. For example, the Pennsylvania Rules of Civil Procedure state:
Rule 1901. Prompt disposition of matters; termination of inactive cases.
(a) General policy.-It is the policy of the unified judicial system to bring each pending matter to a final conclusion as promptly as possible consistently with the character of the matter and the resources of the system. Where a matter has been inactive for an unreasonable period of time, the tribunal, on its own motion, shall enter an appropriate order terminating the matter.
