Civil Procedure Multistate Bar Practice Exam

Which of the following is NOT a requirement for issue preclusion?

1. Same issue actually litigated in case 1

2. The losing party must have appealed case 1

3. Valid, final judgment on the merits

4. Issue was essential to the judgment in case 1

The correct answer is: The losing party must have appealed case 1

The correct choice illustrates a fundamental aspect of issue preclusion, also known as collateral estoppel. For issue preclusion to apply, it is essential that the issue at hand was actually litigated and determined in a previous case, and that this determination was part of a valid and final judgment on the merits. Additionally, the issue must have been essential to the judgment, meaning it needed to be necessary for the court’s decision in the first case. The requirement that the losing party must have appealed the decision in the first case is not necessary for issue preclusion to apply. The lack of an appeal does not affect the binding nature of the judgment on the parties regarding the specific issue that was litigated. As long as the issue was actually contested, resolved, and is related to the parties involved, the outcome in the previous case will typically bind them in future litigation regarding that same issue, regardless of whether there was an appeal. This principle is designed to promote judicial efficiency and prevent contradictory outcomes. Thus, recognizing that an appeal is not a requirement for issue preclusion is crucial in understanding how this doctrine operates in civil procedure.
