Rule 41(a)(1)(B) provides that if the plaintiff has previously dismissed any action based on the same claim, the notice of dismissal operates as what?

• A. An Adjudication On The Merits
• B. A Void Dismissal
• C. A Reversal Of Judgment
• D. A Stay Pending Appeal

Answer: (A)

The rule tests how repeated voluntary dismissals are treated. Under this provision, if the plaintiff has previously dismissed an action based on the same claim, a later notice of dismissal operates as an adjudication on the merits. In other words, the dismissal is treated as if the court had actually ruled on the merits of the claim, yielding a final judgment on the claim and typically precluding refiling of the same claim (res judicata effects).

This isn’t a void dismissal, a reversal of a judgment, or a stay pending appeal. It is a mechanism to achieve finality by treating the dismissal as a merits adjudication, helping prevent gamesmanship through repeated dismissals.
