Class actions are a type of action that most people have heard of but that may not be well understood. In Klier v. Elf Atochem North America, Inc. a class action was initiated against the operator of an industrial plant in Bryan, Texas. The class was divided into three subclasses for the purposes of settlement. Members of each class were granted specific remedies for their disparate injuries.
Class actions are a useful tool when a large number of people have been harmed by a single defendant but none or few of them have suffered sufficient harm to warrant filing an independent claim. Class action proceedings have res judicata power over plaintiffs who do not opt out. That means that if a plaintiff does not opt out of a class action, the verdict or settlement that results will be binding on that person and prevent them from filing that same claim in the future. If a plaintiff feels that his or her injury warrants a separate claim, that person is free to do so only after opting out of the class action.
In order to certify a class for a class action under the Federal Rules of Civil Procedure in the first place, a court must find that the class is so numerous that joinder of all members is impracticable, that there are questions of law or fact common to the class, that the claims or defenses of the representative parties are typical of the claims and defenses of the class and that the representative parties will fairly and adequately protect the interests of the class. Each of these requirements must be met in order for an action to go forward as a class action.
