The internet presents challenges for private international law. One challenge relates to jurisdiction, which is traditionally based on territory. Transactions on the internet span many borders. When cross-border wrongs are committed they may lead to transnational litigation. This article examines the circumstances in which a court can exercise jurisdiction over a foreign defendant alleged to have committed a civil wrong over the internet. Section I examines the background to jurisdiction and the internet and sets the scope of the topic. Section n gives a brief summary of the internet and its applications. Section HI examines jurisdictional rules in civil wrongs cases.The focus is on two sets of rules commonly applied around the globe: the service abroad provisions and the special jurisdiction provisions. Section IV aims to apply those jurisdictional rules to cases of wrongs committed on the internet. It advances general principles, applicable in cases of cross-border wrongs committed on the internet, relating to the place where a wrong is committed and the place where damage is suffered. Defamation has its own peculiarities and is discussed separately. The issue of whether a court can grant an injunction against a foreign defendant in respect of foreign conduct is explored. The article concludes (in Section V) that existing jurisdictional rules need not be amended in light of the internet, and offers general statements about how jurisdictional rules apply to wrongs committed on the internet.
