General question: do class action lawsuits need to be sponsored/initiated by an actual plaintiff, or can lawyers just start a bunch of class actions hoping one will eventually stick and they'll get some fees out of them?
The procedure for filing a class action is to file suit with one or several named plaintiffs on behalf of a proposed class. The proposed class must consist of a group of individuals or business entities that have suffered a common injury or injuries. Typically these cases result from an action on the part of a business or a particular product defect or policy that applied to all proposed class members in a typical manner. After the complaint is filed, the plaintiff must file a motion to have the class certified. In some cases class certification may require discovery in order to determine its size and if the proposed class meets the standard for class certification.
Upon the motion to certify the class, the defendants may object to whether the issues are appropriately handled as a class action, to whether the named plaintiffs are sufficiently representative of the class, and to their relationship with the law firm or firms handling the case. The court will also examine the ability of the firm to prosecute the claim for the plaintiffs, and their resources for dealing with class actions.
