In these days of frequent travel and of corporations doing business in many states, a plaintiff with a transitory cause of action often can get personal service on defendant in more than one jurisdiction. This privilege may be abused, and to meet such abuse a plea of forum non conveniens is proper, the substance of which, as its name implies, is that the forum is not appropriate for the trial of the suit. Where either of the parties is a resident, or where the cause of action arose within the jurisdiction, the forum will usually be as appropriate as any, and the normal set-up making this plea proper will be one where both plaintiff and defendant are nonresidents, and the cause of action arose in some other jurisdiction.
