In its Ruling No. 110 Tai-Kang 1019, the Supreme Court affirms the Taiwan High Court’s finding that Article 20 of the Code of Civil Procedure can’t be applied by analogy as the basis of joint jurisdiction among the defendants from different jurisdictions. The Court can exercise jurisdiction in a case brought against those defendants whose main office and/or domicile are located in Taiwan. Yet, it seemed the Court failed to consider whether Taiwan Court is the Proper Forum to hear this foreign public nuisance dispute. This article points out that the Special Circumstance Theory was not appropriately applied by the court. The author further appeals that there could be room for the court to apply the Doctrine of Forum Non Conveniens in the future while hearing a complex litigation like this.
