One of the key questions addressed within conflict of laws is the determination of when the legislature of a given jurisdiction may legislate, or the court of a given jurisdiction can properly adjudicate, regarding a matter that has extra-jurisdictional dimensions. This is known as "jurisdiction" (sometimes subdivided into "adjudicative jurisdiction", the authority to hear a certain case, and "prescriptive jurisdiction", the authority of a legislature to pass laws covering certain conduct). Like all aspects of conflict of laws, this question is in the first instance resolved by domestic law, which may or may not incorporate relevant international treaties or other supranational legal concepts. That said, relative to the other two main subtopics of conflicts of law (enforcement of judgements, and choice of law, which are both discussed below), the theory regarding jurisdiction has developed consistent international norms. This is perhaps because, unlike the other subtopics, jurisdiction relates to the particularly thorny question of when it is appropriate for a country to exercise its coercive power at all, rather that merely how it should do so.
