E. I. du Pont de Nemours & Co. v. Abbott

This case involves a dispute over whether the results of a few early test trials in a large multi-district litigation can prevent a defendant from defending against liability in thousands of subsequent cases brought by different plaintiffs. Specifically, DuPont challenges the lower court's use of nonmutual offensive collateral estoppel to bind it to adverse findings on duty, breach, and foreseeability from previous bellwether trials.
