Practice question
A competent court's final merits judgment between A and B necessarily determines the authenticity of a particular deed. In a later different-cause action between them, the identical authenticity issue is essential again. No legally relevant exception applies. What doctrine may settle that issue?
- A rule that different causes eliminate all preclusive effects.
- A new automatic trial of the identical issue in every case.
- Only the plaintiff's preference.
- Conclusiveness of judgment.
- A rule that the first judgment decides every unrelated deed.
