Under Wisconsin Statutes §803.08, when the same product has harmed many consumers, their claims may be combined in a single case known as a class action lawsuit. A class-action lawsuit is a civil legal action in which one or more individuals, known as a representative party, sue on behalf of a larger group, known as a class. The requirements for a class-action are: the number of injured people is so large that joining all members is not practical; there are questions of fact or law common to the class; the claims or defenses of the representative parties are typical of the claims or defenses of the class; the representative parties will adequately and fairly protect the interests of the class.
