The Long Arm of US Jurisdiction and International Law: Extraterritoriality against Sovereignty

Abstract

One of the corollaries of sovereignty is the duty of non-intervention in exclusive jurisdiction of other States. But sovereignty can also be the reason why States seek to apply their jurisdictions as far as they can, so some of them have adopted extraterritorial policies in exercising their jurisdictions. In this regard, the US promulgated a series of extraterritorial legislations in respect to competition law and sanctions, which affected non-target States. To counter this long –arm of US jurisdiction, some States took measures of their own to nullify these extraterritorial laws. These measures could be described as jurisdictional countermeasures.
