Rule 23 of the Federal Rules of Civil Procedure establishes impracticability as one of the grounds for permitting a Class Action in federal courts. "[T]he class is so numerous that Joinder of all members is impracticable." In such a situation, the court will permit a few individuals who have made a motion to it to represent in one lawsuit a large number of persons who will be similarly affected by the legal out-come of the particular action. The group to be represented must be so large that there would be significant problems or impracticability in bringing each member before the court to appear as a party to the action. For purposes of certification as a class, the prospective representatives must show that joinder can be accomplished only with substantial difficulty, expense, and hardship, but not that such joinder cannot be done at all. State procedural rules also require that joinder of all prospective class members be impracticable before permitting the commencement of a class action in state courts.
