The civil litigation system aims to resolve disputes in an efficient, centralized, and final manner. In the context of mass tort litigation, one technique courts often use to achieve these goals is what I call “scaling up”: holding individual trials, and then applying results from these trials to similarly situated individuals. Scaling up, however, presents two difficulties. First, the technique risks compromising defendants’ Due Process rights by creating impermissible settlement pressure. Second, scaling up requires the initial court to structure the litigation so that it may serve as a template for follow-on proceedings; where this is not done, attempting to graft the results of one proceeding onto the remaining group of similarly situated individuals may simply lead to more protracted litigation.
Yet these difficulties are not inherent to the technique; in fact, courts can scale up in a way that avoids these problems. In order to mitigate the Due Process problem, courts should not apply the results of individual trials to subsequent trials involving similar claims until a substantial number of trials have been completed, and until it has become clear that any verdicts unfavorable to defendants are not flukes or outliers. And to ensure that scaling up does not simply lead to more protracted litigation, the initial trials should be structured so as to maximize the likelihood that individuals in follow-on litigation can invoke the findings under the issue preclusion doctrine of Parklane Hosiery v. Shore. The American Law Institute has made a proposal with these considerations in mind with respect to issue classes. This Note argues that a similar approach should be taken in the Multidistrict Litigation (MDL) process, where most mass tort litigation occurs today. This approach would be particularly useful if applied to one device that is being used with increasing frequency in the MDL process: the bellwether trial.
