Narrative Opinion Summary
In this case, the appellant, a former employee of Mobil Oil, brought forth claims of wrongful termination and disability discrimination following his dismissal in 2000. The district court had excluded evidence related to environmental issues, citing collateral estoppel, which resulted in a jury verdict favoring Mobil. The appellant challenged this exclusion on appeal. The appellate court examined the applicability of collateral estoppel under California law, recognizing that the environmental issues were not conclusively determined in the prior state court action. Consequently, the exclusion of evidence was deemed improper in relation to the retaliation claim, warranting a reversal. However, concerning the discrimination claim, the court found the exclusion to be a harmless error, as the jury’s decision would likely remain unchanged even with the evidence. The court also addressed the district court’s reliance on collateral estoppel rather than Federal Rule of Evidence 403. Ultimately, the appellate court reversed the district court's ruling on the wrongful termination claim, affirmed the discrimination claim verdict, and remanded the case, with each party bearing its own costs on appeal. The decision has been designated as non-precedential under Ninth Circuit Rule 36-3.
