Forum non conveniens differs from traditional jurisdictional challenges in that it addresses whether a case should proceed in a particular forum, even when the court has jurisdiction, based on factors like convenience and fairness. Traditional jurisdictional challenges, on the other hand, question whether a court has the legal authority to hear a case, typically focusing on the defendant's connection to the forum or the nature of the dispute. Forum non conveniens is used when a court has jurisdiction but another forum is more appropriate due to factors such as the location of evidence, witnesses, or the parties' connections to the forum. While traditional jurisdictional challenges are suited for cases where a court’s authority is at issue, forum non conveniens is often applied in complex cross-border cases where another venue offers a more convenient and efficient resolution.
