International versus 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 concept of jades law 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, e.g. 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 its sovereignty and withdraws from the Union.

State level

Within each state, it is for the government to determine the allocation of jurisdiction:

1. There must be physical distribution of courts and tribunals throughout the territory which should be divided into convenient functional divisions to provide an effective service to the local communities. Hence, it may be convenient for there to be an extensive network of smaller local courts having a criminal law jurisdiction so that neighborhoods can have a disposition system administered by those familiar with their locality and its needs (see criminal jurisdiction). Whereas more specialized civil and commercial courts need only be located in larger towns and major cities where there is a demand for the particular specialisms consistent with the economic costs of providing the facilities and personnel to staff them. Each court system lays down detailed rules for determining who may invoke the jurisdiction in each of the various divisions. In addition to the possibility that the plaintiff has a local domicile, nationality or habitual residence, these conditions may vary from minimum residence requirements for those more transiently present, that business has been conducted within the territory or that there is some other real connection between the plaintiff and/or the cause of action and the state in which the lawsuit has been filed.

2. The government may decide that individuals within the executive should have the power to make judicial or quasi-judicial decisions, and the extent to which the exercise of this jurisdiction should be subject to review by the courts. This has constitutional implications in that many states operate on the basis of the separation of powers which requires that each branch of government operates as a check on the potential abuse of power by the others. Within the formalized judicial structure, jurisdiction may also be granted to individuals for the provision of specialized functions (e.g. the role of special referees or those individuals of prestige commissioned to conduct inquiries into specific situations with the power to compel testimony). In parallel to the courts system, other tribunals and quasi-judicial bodies may also have a form of jurisdiction, e.g. for arbitration, mediation, etc within a broad framework of alternative dispute resolution. Under normal circumstances, the supervisory function of the courts will be built into the constitutive process for each tribunal or body, or the courts will allow their jurisdiction to be invoked, e.g. by way of remedies such as certiorari, to ensure that justice is seen to be done. However, some well-established bodies such as the Beth Din represent more interesting challenges. Such religious or culturally-based courts often have significant power within the relevant communities yet, in an increasingly multi-ethnic, multi-cultural world, the secular or culturally-different majority in each state cannot be seen to be too quick to interfere and impose its standards without appearing to engage in unequal treatment and discrimination.
