Hells Canyon Preservation Council v. United States forest Service

When a party withdraws one of its claims before the trial court enters judgment and the action is subsequently dismissed on the merits, does the trial courts failure to indicate that the withdrawn claim was dismissed without prejudice necessarily render its decision a "final judgment on the merits" as to that claim? Because we answer this question in the negative, we reverse the district courts dismissal of this suit on res judicata grounds and remand for further proceedings.
