A class-action lawsuit is a type of lawsuit in which a group of people with similar injuries or grievances caused by the same product or action sue a defendant as a group. The group of people who are filing the lawsuit are generally represented collectively by a member of that group. Often, it is simpler to combine many lawsuits into a class-action lawsuit. The benefit of a class-action lawsuit is that a collection of injuries or grievances can be more powerful in a court of law than individual complaints. Additionally, filing a class-action lawsuit leads to a consolidation of evidence, attorneys, and witnesses that can make the case more efficient. Historically, class-action lawsuits have been filed against companies, organizations, or governments.
