The International Court of Justice, or colloquially the World Court, is the only international court that adjudicates general disputes between nations, and gives advisory opinions on international legal issues. It is one of the six organs of the United Nations (UN), and is located in The Hague, Netherlands.
Jurisdiction is the legal term for the legal authority granted to a legal entity to enact justice. In federations like the United States, the concept of jurisdiction applies at multiple levels.
The LaGrand case was a legal action heard before the International Court of Justice (ICJ) which concerned the Vienna Convention on Consular Relations. In the case, the ICJ ruled that its own temporary court orders were legally binding and that the rights contained in the convention could not be denied by the application of domestic legal procedures.
The following outline is provided as an overview of and introduction to law:
The Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG), or the Genocide Convention, is an international treaty that criminalizes genocide and obligates state parties to pursue the enforcement of its prohibition. It was the first legal instrument to codify genocide as a crime, and the first human rights treaty unanimously adopted by the United Nations General Assembly, on 9 December 1948, during the third session of the United Nations General Assembly. The Convention entered into force on 12 January 1951 and has 153 state parties as of June 2024.
A legal custom is the established pattern of behavior within a particular social setting. A claim can be carried out in defense of "what has always been done and accepted by law".
Legality of the Threat or Use of Nuclear Weapons[1996] ICJ 3 is a landmark international law case, where the International Court of Justice gave an advisory opinion stating that while the threat or use of nuclear weapons would generally be contrary to international humanitarian law, it cannot be concluded whether or not such a threat or use of nuclear weapons would be lawful in extreme circumstances where the very survival of a state would be at stake. The Court held that there is no source of international law that explicitly authorises or prohibits the threat or use of nuclear weapons but such threat or use must be in conformity with the UN Charter and principles of international humanitarian law. The Court also concluded that there was a general obligation to pursue nuclear disarmament.
Customary international law are international obligations arising from established or usual international practices, which are less formal customary expectations of behavior often unwritten as opposed to formal written treaties or conventions. Customary international law is an aspect of international law involving the principle of custom. Along with general principles of law and treaties, custom is considered by the International Court of Justice, jurists, the United Nations, and its member states to be among the primary sources of international law.
The International law bearing on issues of Arab–Israeli conflict, which became a major arena of regional and international tension since the birth of Israel in 1948, resulting in several disputes between a number of Arab countries and Israel.
International law, also known as "law of nations", refers to the body of rules which regulate the conduct of sovereign states in their relations with one another. Sources of international law include treaties, international customs, general widely recognized principles of law, the decisions of national and lower courts, and scholarly writings. They are the materials and processes out of which the rules and principles regulating the international community are developed. They have been influenced by a range of political and legal theories.
Opinio juris sive necessitatis or simply opinio juris is the belief that an action was carried out as a legal obligation. This is in contrast to an action resulting from cognitive reaction or behaviors habitual to an individual. This term is frequently used in legal proceedings such as a defense for a case.
The International Court of Justice has jurisdiction in two types of cases: contentious cases between states in which the court produces binding rulings between states that agree, or have previously agreed, to submit to the ruling of the court; and advisory opinions, which provide reasoned, but non-binding, rulings on properly submitted questions of international law, usually at the request of the United Nations General Assembly. Advisory opinions do not have to concern particular controversies between states, though they often do.
International law is the set of rules, norms, and standards that states and other actors feel an obligation to obey in their mutual relations and generally do obey. In international relations, actors are simply the individuals and collective entities, such as states, international organizations, and non-state groups, which can make behavioral choices, whether lawful or unlawful. Rules are formal, often written expectations for behavior and norms are less formal, customary expectations about appropriate behavior that are frequently unwritten. It establishes norms for states across a broad range of domains, including war and diplomacy, economic relations, and human rights.
Perú v. Chile was a public international law case concerning a territorial dispute between the South American republics of Peru and Chile over the sovereignty of an area at sea in the Pacific Ocean approximately 37,900 square kilometres (14,600 sq mi) in size. Peru contended that its maritime boundary delimitation with Chile was not fixed, but Chile claimed that it holds no outstanding border issues with Peru. On January 16, 2008, Peru brought forth the case to the International Court of Justice at The Hague, the Netherlands, which accepted the case and formally filed it as the Case concerning maritime delimitation between the Republic of Peru and the Republic of Chile - Perú v. Chile.
The Martens Clause is an early international law concept first introduced into the preamble of the 1899 Hague Convention II – Laws and Customs of War on Land. There are differing interpretations of its significance on modern international law, with some scholars simply treating the clause as a reminder international customary law still applies after a treaty is ratified while others take a more expansive approach where the clause provides that because international treaties cannot be all encompassing, states cannot use that as a justification for an action.
Medellín v. Texas, 552 U.S. 491 (2008), was a decision of the United States Supreme Court that held even when a treaty constitutes an international commitment, it is not binding domestic law unless it has been implemented by an act of the U.S. Congress or contains language expressing that it is "self-executing" upon ratification. The Court also ruled that decisions of the International Court of Justice are not binding upon the U.S. and, like treaties, cannot be enforced by the president without authority from Congress or the U.S. Constitution.
An atrocity crime is a violation of international criminal law that falls under the historically three legally defined international crimes of genocide, war crimes, and crimes against humanity. Ethnic cleansing is widely regarded as a fourth mass atrocity crime by legal scholars and international non-governmental organizations (NGOs) working in the field, despite not yet being recognized as an independent crime under international law.
In international law, a persistent objector is a sovereign state which has consistently and clearly objected to a norm of customary international law since the norm's emergence, and considers itself not bound to observe the norm. The concept is an example of the positivist doctrine that a state can only be bound by norms to which it has consented.
