Under Rule 41(a)(1)(B), the adjudication on the merits applies when the prior dismissal was in which action type?

• A. Federal Or State Action
• B. Criminal Action
• C. Bankruptcy Action
• D. Foreign Action

Answer: (A)

Rule 41(a)(1)(B) ties the “adjudication on the merits” effect to prior dismissals that occurred in civil actions in federal or state courts. If the plaintiff previously dismissed a federal- or state-court action based on or including the same claim, the current action on that claim is treated as having been adjudicated on the merits, and the suit can be barred or dismissed with prejudice as a final merits determination. This power does not extend to prior dismissals in criminal cases, bankruptcy proceedings, or foreign actions, which aren’t covered by this provision. So the correct answer is that the adjudication-on-the-merits effect applies when the prior dismissal was in a federal or state civil action.
