International Court of Justice (ICJ), the principal judicial organ of the United Nations (UN). The idea for the creation of an international court to arbitrate international disputes first arose during the various conferences that produced the Hague Conventions in the late 19th and early 20th centuries. The body subsequently established, the Permanent Court of Arbitration, was the precursor of the Permanent Court of International Justice (PCIJ), which was established by the League of Nations. From 1921 to 1939 the PCIJ issued more than 30 decisions and delivered nearly as many advisory opinions, though none were related to the issues that threatened to engulf Europe in a second world war in 20 years. The ICJ was established in 1945 by the San Francisco Conference, which also created the UN. All members of the UN are parties to the statute of the ICJ, and nonmembers may also become parties. The court’s inaugural sitting was in 1946.

The ICJ is a continuing and autonomous body that is permanently in session. It consists of 15 judges—no two of whom may be nationals of the same state—who are elected to nine-year terms by majority votes in the UN General Assembly and the Security Council. The judges, one-third of whom are elected every three years, are eligible for reelection. The judges elect their own president and vice president, each of whom serves a three-year term, and can appoint administrative personnel as necessary.

The seat of the ICJ is at The Hague, but sessions may be held elsewhere when the court considers it desirable to do so. The official languages of the court are French and English.

The court’s primary function is to pass judgment upon disputes between sovereign states. Only states may be parties in cases before the court, and no state can be sued before the World Court unless it consents to such an action. Under article 36 of the court’s statute, any state may consent to the court’s compulsory jurisdiction in advance by filing a declaration to that effect with the UN secretary-general, and by 2000 more than 60 countries had issued such a declaration. The declaration (the “optional clause”) may be made unconditionally, or it may be made on condition of reciprocity on the part of other states or for a certain time. In proceedings before the court, written and oral arguments are presented, and the court may hear witnesses and appoint commissions of experts to make investigations and reports when necessary.

Cases before the ICJ are resolved in one of three ways: (1) they can be settled by the parties at any time during the proceedings; (2) a state can discontinue the proceedings and withdraw at any point; or (3) the court can deliver a verdict. The ICJ decides disputes in accordance with international law as reflected in international conventions, international custom, general principles of law recognized by civilized nations, judicial decisions, and writings of the most highly qualified experts on international law. Although the judges deliberate in secret, their verdicts—rendered in both English and French—are delivered in open court. Any judge who does not agree in whole or in part with the court’s decision may file a separate opinion, and few decisions represent the unanimous opinion of the judges. The court’s judgment is final and without appeal.

The court’s decisions, numbering approximately 70 from 1946 to 2000, are binding on the parties and have been concerned with issues such as land and maritime boundaries, territorial sovereignty, diplomatic relations, the right of asylum, nationality, and economic rights. The ICJ is also empowered to give advisory opinions on legal questions at the request of other organs of the UN and its specialized agencies when authorized to do so by the General Assembly. Although advisory opinions—numbering about 25 over its first 50 years—are not binding and are only consultative, they are considered important. They have been concerned with issues such as admission to the UN, the expenses of UN operations, and the territorial status of South West Africa (Namibia) and Western Sahara. The court may also be granted jurisdiction over certain cases by treaty or convention. By the late 1990s approximately 400 bilateral and multilateral treaties deposited at the UN conferred compulsory jurisdiction to the ICJ.

The court itself has no powers of enforcement, but according to article 94 of the Charter of the United Nations:

If any party to a case fails to perform the obligations incumbent upon it under a judgment rendered by the Court, the other party may have recourse to the Security Council, which may, if it deems necessary, make recommendations or decide upon measures to be taken to give effect to the judgment.

Few state parties to a case before the ICJ (or before its predecessor, the PCIJ) have failed to carry out the court’s decisions. Two exceptions are Albania, which failed to pay £843,947 in damages to the United Kingdom in the Corfu Channel case (1949), and the United States, which refused to pay reparations to the Sandinista government of Nicaragua (1986). The United States also withdrew its declaration of compulsory jurisdiction and blocked Nicaragua’s appeal to the UN Security Council. In general, however, enforcement is made possible because the court’s decisions, though few in number, are viewed as legitimate by the international community.

international law, the body of legal rules, norms, and standards that apply between sovereign states and other entities that are legally recognized as international actors. The term was coined by the English philosopher Jeremy Bentham (1748–1832).

The nature and development of international law

Definition and scope

According to Bentham’s classic definition, international law is a collection of rules governing relations between states. It is a mark of how far international law has evolved that this original definition omits individuals and international organizations—two of the most dynamic and vital elements of modern international law. Furthermore, it is no longer accurate to view international law as simply a collection of rules; rather, it is a rapidly developing complex of rules and influential—though not directly binding—principles, practices, and assertions coupled with increasingly sophisticated structures and processes. In its broadest sense, international law provides normative guidelines as well as methods, mechanisms, and a common conceptual language to international actors—i.e., primarily sovereign states but also increasingly international organizations and some individuals. The range of subjects and actors directly concerned with international law has widened considerably, moving beyond the classical questions of war, peace, and diplomacy to include human rights, economic and trade issues, space law, and international organizations. Although international law is a legal order and not an ethical one, it has been influenced significantly by ethical principles and concerns, particularly in the sphere of human rights.

International law is distinct from international comity, which comprises legally nonbinding practices adopted by states for reasons of courtesy (e.g., the saluting of the flags of foreign warships at sea). In addition, the study of international law, or public international law, is distinguished from the field of conflict of laws, or private international law, which is concerned with the rules of municipal law—as international lawyers term the domestic law of states—of different countries where foreign elements are involved.

International law is an independent system of law existing outside the legal orders of particular states. It differs from domestic legal systems in a number of respects. For example, although the United Nations (UN) General Assembly, which consists of representatives of some 190 countries, has the outward appearances of a legislature, it has no power to issue binding laws. Rather, its resolutions serve only as recommendations—except in specific cases and for certain purposes within the UN system, such as determining the UN budget, admitting new members of the UN, and, with the involvement of the Security Council, electing new judges to the International Court of Justice (ICJ). Also, there is no system of courts with comprehensive jurisdiction in international law. The ICJ’s jurisdiction in contentious cases is founded upon the consent of the particular states involved. There is no international police force or comprehensive system of law enforcement, and there also is no supreme executive authority. The UN Security Council may authorize the use of force to compel states to comply with its decisions, but only in specific and limited circumstances; essentially, there must be a prior act of aggression or the threat of such an act. Moreover, any such enforcement action can be vetoed by any of the council’s five permanent members (China, France, Russia, the United Kingdom, and the United States). Because there is no standing UN military, the forces involved must be assembled from member states on an ad hoc basis.

International law is a distinctive part of the general structure of international relations. In contemplating responses to a particular international situation, states usually consider relevant international laws. Although considerable attention is invariably focused on violations of international law, states generally are careful to ensure that their actions conform to the rules and principles of international law, because acting otherwise would be regarded negatively by the international community. The rules of international law are rarely enforced by military means or even by the use of economic sanctions. Instead, the system is sustained by reciprocity or a sense of enlightened self-interest. States that breach international rules suffer a decline in credibility that may prejudice them in future relations with other states. Thus, a violation of a treaty by one state to its advantage may induce other states to breach other treaties and thereby cause harm to the original violator. Furthermore, it is generally realized that consistent rule violations would jeopardize the value that the system brings to the community of states, international organizations, and other actors. This value consists in the certainty, predictability, and sense of common purpose in international affairs that derives from the existence of a set of rules accepted by all international actors. International law also provides a framework and a set of procedures for international interaction, as well as a common set of concepts for understanding it.
