Sixth Circuit validates challenge to PFAS class – demands greater specificity in pleading standards for causationNovember 30, 2023 On November 27, a landmark PFAS decision by the Sixth Circuit effectively dismissed a statewide class action for lack of standing. This potentially sets the stage for a new era of PFAS litigation, where historically general and conclusory allegations by PFAS plaintiffs must be substituted with particularized pleadings connecting each defendant to the detected PFAS compound in the plaintiff’s body. Businesses at risk of being named defendants in PFAS litigation might use this decision to guide their risk assessments and pre-litigation avoidance and mitigation strategies, including ramping up diligence on information necessary to advance early phase dismissal efforts in litigation. District Court certifies statewide class Appellate Court vacates class certification, orders dismissal The Sixth Circuit focused on traceability, requiring the plaintiff to allege “facts plausibly supporting an inference that each defendant ‘likely caused’ at least one of those PFAS compounds to end up in his blood.” The court found that the plaintiff failed here on two grounds. First, the court rejected collective allegations against all defendants, as the plaintiff “must tie his injury to each defendant” (i.e., go beyond “Defendants” manufactured, released, made repeated assurances about, encouraged use of PFAS, etc.). A plaintiff may not sue multiple defendants by lumping them together in general allegations when more particular facts would allow a plaintiff to proceed only against some defendants.
