Ninth Circuit clarifies affirmative defense standard for FRSA retaliation claims: Parker v. BNSF Railway Company

In Parker v. BNSF Railway Company (9th Cir. 2024) 112 F.4th 687, the Court of Appeals for the Ninth Circuit clarified the standard for the FRSA’s “same decision” affirmative defense, holding 2-1 that once a plaintiff shows protected activity was a “contributing factor,” the employer must then prove by clear and convincing evidence it would have taken the same adverse action absent that activity. 

Defendant terminated Plaintiff partly for “failure to work efficiently,” which Plaintiff alleged was connected to his refusal to skip a mandatory air-brake test. Following partial summary judgment for Plaintiff and a jury verdict in his favor, the Ninth Circuit vacated the verdict and remanded, holding Plaintiff was not entitled to summary judgment on the “contributing factor” element. In a subsequent bench trial, the district court found that Plaintiff’s protected activity was a contributing factor in his termination but that it “contributed very little” to the decision. The district court ruled for Defendant, and Plaintiff appealed.

On appeal, The Ninth Circuit reversed. It held that under 49 U.S.C. § 20109(a)(2), an employer cannot discharge an employee for protected activity even “in part.” The Ninth Circuit remanded because the district court failed to determine if BNSF met its burden for the affirmative defense, which required proving by clear and convincing evidence that it would have terminated Plaintiff absent the protected activity (not just that it could have). The court also ruled that Plaintiff failed to show prejudice from the lower court’s evidentiary rulings.
