Penn. Appeals Court Affirms Decertification of Class Because "Statistical Probability Does Not Substitute for Actual Inquiry"
A Pennsylvania intermediate appellate court yesterday affirmed a trial court's decertification of a statewide class action alleging plaintiffs had suffered economic harm from taking Neurontin for uses not approved by the FDA. See Clark v. Pfizer Inc., No. 754 EDA 2009, 2010 Pa. Super. 6, Slip op. (Pa. Super. Jan. 19, 2010). In doing so, the court rejected a "fraud on the market" theory and so-called "statistical proof" of causation. Because my Skadden colleagues worked on the appeal, I'll only briefly summarize its holdings here.
Plaintiffs often cite to Pennsylvania precedents that encourage early and liberal certification of class actions. But the corollary to such a liberal certification rule, of course, is that where discovery presents evidence that the case cannot be manageably tried as a class, the trial court retains the discretion to decertify the class. That is what happened in Clark: the trial court originally had certified a class of Pennsylvania residents, but after discovery and upon the evidence, the court then decertified the class. It also found that people who benefitted from taking Neurontin could not state a claim, and so it had granted summary judgment as to those class members who had benefitted from taking the medicine. And it granted summary judgment on the express warranty claim because there was no proof that plaintiffs had received any warranties.
Plaintiffs complained that the trial court -- by granting summary judgment and then decertifying the class -- had put them in an impossible position where absent class members arguably were bound by substantive judgments on their claims, but could not appeal them because there was no proper class. Under the circumstances, the Superior Court effectively agreed and reversed the trial court's two grants of summary judgment. Slip op. at 24-25.
But the Superior Court affirmed the trial court's decertification of the class. The trial court had decertified the class because there were individual questions for each class member as to whether he or she had benefitted from taking Neurontin. Although the Superior Court acknowledged that this was true, it stressed that the real reason the class could not be certified was that the proposed class failed the typicality, commonality and predominance requirements of the class action rule. Why? Because causation (i.e. reliance by each class member's doctor upon a misrepresentation) could not be presumed:
Where there exists various intervening and possibly superseding causes of the damage, liability cannot be determined on a class-wide basis because individual issues would predominate issues of fact and law that are common to the class and the representatives of the class.
Slip op. at 10 (citation omitted).
Plaintiffs' expert had relied on statistical modeling to opine that virtually all of the class members' doctors had relied on the defendants' alleged misrepresentations to prescribe Neurontin for uses not approved by the FDA. But as a result of discovery, defendants had introduced testimony from Pennsylvania doctors establishing that their prescriptions were based on other factors, not any so-called "misrepresentations." Citing to the decision in the federal MDL -- In re Neurontin Marketing, Sales Practices & Products Liability Litigation, 257 F.R.D. 315 (D. Mass. 2009) -- the Superior Court rejected any "presumption of causation" or "fraud-on-the-market theory" (slip op. at 11), holding instead that each class member must establish reliance/causation on his or her own to establish a right to recover (id. at 15). As the court put it:
In sum, statistical probability does not substitute for actual inquiry, as a general showing of percentages does not tend to prove that the class members' specific doctors relied upon Defendants' statements or that Defendants' statements were the proximate cause of an injury.
Slip op. at 16.
Because the issue of causation was an individual question for each class member, the case could not be tried as a class action.
