Jurisdiction (from the Latin ius, iuris meaning "oath" and dicere meaning "to speak") is the practical authority granted to a formally constituted legal body or to a political leader to deal with and make pronouncements on legal matters and, by implication, to administer justice within a defined area of responsibility. The term is also used to denote the geographical area or subject-matter to which such authority applies. Jurisdiction draws its substance from public international law, conflict of laws, constitutional law and the powers of the executive and legislative branches of government to allocate resources to best serve the needs of its native society.

There are three main principles of judicial jurisdiction: personal (personam), territorial (locum), and subject matter (subjectam):
Courts may also have jurisdiction that is exclusive, or concurrent (shared). Where a court has exclusive jurisdiction over a territory or a subject matter, it is the only court that is authorized to address that matter. Where a court has concurrent or shared jurisdiction, more than one court can adjudicate the matter. Where a concurrent jurisdiction exists in a civil case, a party may attempt to engage in forum shopping, by bringing the case to a court or venue which it presumes would rule in its favor. and municipal jurisdiction The fact that international organizations, courts and tribunals have been created raises the difficult question of how to co-ordinate their activities with those of national courts. If the two sets of bodies do not have concurrent jurisdiction but, as in the case of the International Criminal Court (ICC), the relationship is expressly based on the principle of complementarity, i.e. the international court is subsidiary or complementary to national courts, the difficulty is avoided. But if the jurisdiction claimed is concurrent, or as in the case of International Criminal Tribunal for the former Yugoslavia (ICTY), the international tribunal is to prevail over national courts, the problems are more difficult to resolve politically. The idea of universal jurisdiction is fundamental to the operation of global organizations such as the United Nations and the International Court of Justice (ICJ), which jointly assert the benefit of maintaining legal entities with jurisdiction over a wide range of matters of significance to states (the ICJ should not be confused with the ICC and this version of "universal jurisdiction" is not the same as that enacted in the War Crimes Law (Belgium) which is an assertion of extraterritorial jurisdiction that will fail to gain implementation in any other state under the standard provisions of public policy). Under Article 34 Statute of the ICJ only states may be parties in cases before the Court and, under Article 36, the jurisdiction comprises all cases which the parties refer to it and all matters specially provided for in the Charter of the United Nations or in treaties and conventions in force. But, to invoke the jurisdiction in any given case, all the parties have to accept the prospective judgment as binding. This reduces the risk of wasting the Court’s time. Despite the safeguards built into the constitutions of most of these organizations, courts and tribunals, the concept of universal jurisdiction is controversial among those states which prefer unilateral to multilateral solutions through the use of executive or military authority, sometimes described as realpolitik-based diplomacy. Within other international contexts, there are intergovernmental organizations such as the World Trade Organization (WTO) that have socially and economically significant dispute resolution functions but, again, even though their jurisdiction may be invoked to hear the cases, the power to enforce their decisions is at the will of the states affected, save that the WTO is permitted to allow retaliatory action by successful states against those states found to be in breach of international trade law. At a regional level, groups of states can create political and legal bodies with sometimes complicated patchworks of overlapping provisions detailing the jurisdictional relationships between the member states and providing for some degree of harmonization between their national legislative and judicial functions, for example, the European Union and African Union both have the potential to become federated states although the political barriers to such unification in the face of entrenched nationalism will be very difficult to overcome. Each such group may form transnational institutions with declared legislative or judicial powers. For example, in Europe, the European Court of Justice has been given jurisdiction as the ultimate appellate court to the member states on issues of European law. This jurisdiction is entrenched and its authority could only be denied by a member state if that member State asserts From Wikipedia, the free encyclopedia : Jurisdiction |
