Jamie Gannon and Rebecca Gannon v. American Home Products, Inc., et al. (A-80-10; 066899)

Federal principles must govern the preclusive effect of a federal judgment. For collateral estoppel purposes, plaintiffs were afforded a full and fair opportunity to be heard on the essential claims of their dispute. The appellate panel erred in concluding that equitable considerations demand that plaintiffs be permitted to have their claims heard again.
