Though the jurisdiction of US courts is broad enough to give many foreign plaintiffs the ability to file suit here, the doctrine of forum non conveniens (FNC) enables a court to dismiss a case because another forum—typically the plaintiff’s home forum—would be more convenient for it. FNC dismissal is warranted only if the alternative forum is adequate, available, and more convenient for the case. Often, the alternative forum’s availability is a nonissue. However, many Latin American countries subscribe to a system of preemptive jurisdiction, which extinguishes their courts’ jurisdiction once a case is filed elsewhere. This system would seem to block the use of FNC by making the alternative forum unavailable, but U.S. courts have not treated this issue consistently. Some courts have reached divergent results using the same evidence, and some have avoided the inquiry altogether by making dismissals conditional. This Note analyzes and explains courts’ inconsistent treatment of Latin American rules of preemptive jurisdiction by illustrating certain subtle but crucial doctrinal missteps. The Note argues that FNC doctrine requires courts to analyze a foreign forum’s availability from that forum’s perspective while also paying heed to the movant’s burden of persuasion. Yet this doctrinally honest approach could preclude courts from using FNC to mediate between important policy concerns, as is usually possible. This Note identifies these competing concerns and proposes a possible solution.
