INTRODUCTION
Jurisdiction is the practical authority granted to a formally constituted legal body or to a political le adder to deal with and make pronouncements on legal matters and, by implication, to administer justice within a defined area of responsibility.

The term ‘extraterritorial jurisdiction’ is only accurate if it refers to assertions of jurisdiction over persons, property, or activities, which have no territorial nexus whatsoever with the regulating State.
