When the involuntary dismissal is used
Timing: when the plaintiff stops moving the case forward or disobeys an order. Dispositive motions ask the court to decide all or part of a case without a full trial. They usually follow discovery.
What the rule requires
- Unless the dismissal order states otherwise, a dismissal under Rule 41(b) — other than for lack of jurisdiction, improper venue, or failure to join a Rule 19 party — operates as an adjudication on the merits.
In practice, read each requirement closely. Then check whether your court adds anything of its own. For example, many courts set page limits, formatting rules or a duty to confer with the other side first.
