	Introduction

Over the last several years, both the Supreme Court and Congress have actively considered the scope of class action lawsuits. Background

T he class action suit is a procedural device for joining numerous parties in a civil lawsuit when the "issues involved are common to the class as a whole" and when the issues "turn on questions of law applicable in the same manner to each member of the class." Class actions "save[] the resources of both the courts and the parties by permitting an issue potentially affecting every [class member] to be lit igated in an economical fashion .... " The class action also affords aggrieved parties a remedy when it is not economically feasible to obtain relie f, such as where each claim involves only a small dollar amount. The modern class action appears to be derived from the Bill of Peace, an equitable proceeding developed by the English Court of Chancery, which enabled an equity court to hear an action by or against representatives of a group if the plaintiff could establish that the number of people involved was so large as to make traditional joinder impossible or impracticable. Class suits have long been a part of American jurisprudence, starting with their authorization by federal courts under equity rules. These rules gradually became codified at the state and federal level, but were generally restricted to cases where the class shared a common or general interest and where the parties were too numerous for the cases to be combined traditionally under joinder. With the increasing complexity and interconnectedness of modern society, the class action has taken on a more prominent role. Rule 23(b) further requires that one of the following elements be proven by the party seeking to bring the action:
(1) prosecuting separate actions by or against individual class members would create a risk of: (A) inconsistent or varying adjudications with respect to individual class members that would establish incompatible standards of conduct for the party opposing the class; or (B) adjudications with respect to individual class members that, as a practical matter, would be dispositive of the interests of the other members not parties to the individual adjudications or would substantially impair or impede their ability to protect their interests;
(2) the party opposing the class has acted or refused to act on grounds that apply generally to the class, so that final injunctive relief or corresponding declaratory relief is appropriate respecting the class as a whole; or 
(3) the court finds that the questions of law or fact common to class members predominate over any questions affecting only individual members, and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy. In Wal-Mart Stores, Inc. v. Dukes , the Court has limited the ability of plaintiffs who are not similarly situated from bringing class action suits, which may result in smaller class sizes. The Court in Campbell-Ewald Co. v. Gomez declined to find that a defendant's offer to provide complete relief to settle a plaintiff's individual claims would moot a class action lawsuit before certification, which might have made it more difficult for a particular individual to bring a class action. The Court, however, left open the possibility that such an action might be rendered moot by the defendant putting funds in an account payable to the plaintiff. In Tyson Foods, Inc. v. Bouaphakeo , the Court held that each person joined in a class action suit need not prove, individually, that she was harmed by the claimed misconduct, if statistical models can show such harm. Although the Court declined to articulate all the situations in which statistical evidence could be introduced, it left open the possibility that such evidence could be used in a number of future class action cases. In Spokeo, Inc. v. Robins , the Court is still considering whether a class action meets the standing requirements of Article III if the plaintiff suffered a statutory injury but no actual damages. If the Court finds that a statutory injury is sufficient to satisfy Article III, class actions brought under those claims might be more easily certified than class actions where proof of injury may vary from plaintiff to plaintiff. In January 2016, the House passed H.R. 1927 , the Fairness in Class Action Litigation and Furthering Asbestos Claim Transparency Act of 2016. This legislation, if enacted into law, would arguably limit the size of some class action suits by limiting class action suits to class members who have suffered injuries of the same type and scope.
The class action suit is a procedural device for joining numerous parties in a civil lawsuit when the issues involved are common to the class as a whole and when the issues turn on questions of law applicable in the same manner to each member of the class. Class actions are intended to save the resources of both the courts and the parties by permitting an issue potentially affecting every class member to be litigated together in an economical fashion. The class action is also intended to allow parties to pursue a legal remedy when it is not economically feasible to obtain relief, such as where each claim involves only a small dollar amount.
