International lawInternational law (also known as public international law and the law of nations) is the set of rules, norms, and standards generally recognised as binding between states. It establishes normative guidelines and a common conceptual framework for states across a broad range of domains, including war and diplomacy, economic relations, and human rights. International law differs from state-based domestic legal systems in that it is primarily, though not exclusively, applicable to states, rather than to individuals, and operates largely through consent, since there is no universally accepted authority to enforce it upon sovereign states.
Genocide ConventionThe 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.
Customary international lawCustomary 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. Many governments accept in principle the existence of customary international law, although there are differing opinions as to what rules are contained in it.
Vienna Convention on the Law of TreatiesThe Vienna Convention on the Law of Treaties (VCLT) is an international agreement that regulates treaties among sovereign states; the VCLT is a codification of customary international law and state practice concerning treaties. Known as the "treaty on treaties", the VCLT establishes comprehensive, operational guidelines, rules, and procedures for how treaties are drafted, defined, amended, and interpreted.
TortureTorture is the deliberate infliction of severe pain or suffering on a person for reasons such as punishment, extracting a confession, interrogation for information, or intimidating third parties. Some definitions are restricted to acts carried out by the state, but others include non-state organizations. Torture has been carried out since ancient times. In the eighteenth and nineteenth centuries, Western countries abolished the official use of torture in the judicial system, but torture continued to be used throughout the world.
Crimes against humanityCrimes against humanity are widespread or systemic criminal acts which are committed by or on behalf of a de facto authority, usually by or on behalf of a state, that grossly violate human rights. Unlike war crimes, crimes against humanity do not have to take place within the context of wars, and they apply to widespread practices rather than acts which are committed by individuals. Although crimes against humanity apply to acts which are committed by or on behalf of authorities, they do not need to be part of an official policy, and they only need to be tolerated by authorities.
Universal jurisdictionUniversal jurisdiction is a legal principle that allows states or international organizations to claim criminal jurisdiction over an accused person regardless of where the alleged crime was committed, and regardless of the accused's nationality, country of residence, or any other relation to the prosecuting entity. Crimes prosecuted under universal jurisdiction are considered crimes against all, too serious to tolerate jurisdictional arbitrage.
Pacta sunt servandaPacta sunt servanda, Latin for "agreements must be kept", is a brocard and a fundamental principle of law. According to Hans Wehberg, a professor of international law, "few rules for the ordering of Society have such a deep moral and religious influence" as this principle. In its most common sense, the principle refers to private contracts and prescribes that the provisions, i.e. clauses, of a contract are law between the parties to the contract, and therefore implies that neglect of their respective obligations is a violation of the contract.
International Court of JusticeThe International Court of Justice (ICJ; Cour internationale de justice; CIJ), also called the World Court, is one of the six principal organs of the United Nations (UN). It settles disputes between states in accordance with international law and gives advisory opinions on international legal issues. The ICJ is the only international court that adjudicates general disputes between countries, with its rulings and opinions serving as primary sources of international law (subject to Article 59 of the Statute of the International Court of Justice).
European Court of Human RightsThe European Court of Human Rights (ECHR or ECtHR), also known as the Strasbourg Court, is an international court of the Council of Europe which interprets the European Convention on Human Rights. The court hears applications alleging that a contracting state has breached one or more of the human rights enumerated in the convention or its optional protocols to which a member state is a party. The European Convention on Human Rights is also referred to by the initials "ECHR". The court is based in Strasbourg, France.
