A class action is a type of lawsuit in which a large number of persons suffering from similar conditions bring a joint claim against a defendant or a group of defendants they consider liable. The nature of class action lawsuits is probably national, but they must share a common cause. The class must share certain attributes, which include commonality, adequacy, numerosity, and typicality. Class Action lawsuits are usually against government agencies, financial institutions, suppliers, retailers, or employers are sometimes filed. Many are based on claims of faulty goods, misleading advertising, bias, or illegal work practices. Also, by keeping them accountable, class actions will cause irresponsible businesses to change their negligent activities.
