Whether Federal Rule of Civil Procedure 41(b) bars a federal district court from dismissing an action for failure to prosecute unless the defendant first moves for dismissal.
Holding
No. Rule 41(b) does not displace a district court's inherent authority to dismiss an action sua sponte for failure to prosecute.
Reasoning
Rule 41(b) expressly permits a defendant to move for involuntary dismissal when a plaintiff fails to prosecute or comply with court rules or orders. But the Rule's permissive authorization of a defendant's motion does not imply that a court lacks power to act on its own initiative.
The power to dismiss dormant or dilatorily prosecuted actions is an ancient and inherent judicial power. It enables trial courts to manage their calendars, prevent undue delay, and secure the orderly and expeditious disposition of cases.
Nothing in Rule 41(b) clearly abrogates that well-established authority. The Court also noted that federal district courts had widely used sua sponte dismissals to address stale cases, and Rule 83 permitted district courts to regulate practice consistently with the Federal Rules where no Rule controlled the situation.
