Many class action proceedings end in settlement. The settlement agreement is designed, inter alia, to facilitate an efficient and fair resolution to the proceeding, in a manner that also provides certainty to the parties. Essentially, it “takes on the risk” for all parties involved—the class action plaintiffs and their legal representation, the class, and the defendants. Settlement certification by the court constitutes res judicata, and ensures the preclusion of repeated claims regarding the subject of the settlement.
