The procedure for filing a class action is to file suit with one or several named plaintiffs on behalf of a putative class. The putative class must consist of a group of individuals or business entities that have suffered a common wrong. Usually, these kinds of cases are connected to some standard action on the part of a business, or some particular product defect or policy that was applied to all potential class members in a uniform manner. After the summons and complaint is filed, the plaintiff usually has to bring a motion (sometimes at the same time as filing the summons and complaint) to have the class certified. In some jurisdictions class certification may require additional discovery in order to determine if the proposed class is sufficiently cohesive.
