George Shiras, Jr.,
Scott v. Donald (165 U.S. 107)…
“ The theory of the decree is that the plaintiff is one of a class of persons whose rights are infringed and threatened, and that he so represents such class that he may pray an injunction on behalf of all persons that constitute it. It is, indeed, possible that there may be others in like case with the plaintiff, and that such persons may be numerous; but such a state of facts is too conjectural to furnish a safe basis upon which a court of equity ought to grant an injunction. ”
