War of aggressionA war of aggression, sometimes also war of conquest, is a military conflict waged without the justification of self-defense, usually for territorial gain and subjugation. Wars without international legality (i.e. not out of self-defense nor sanctioned by the United Nations Security Council) can be considered wars of aggression; however, this alone usually does not constitute the definition of a war of aggression; certain wars may be unlawful but not aggressive (a war to settle a boundary dispute where the initiator has a reasonable claim, and limited aims, is one example).
Diplomatic immunityDiplomatic immunity is a principle of international law by which certain foreign government officials are recognized as having legal immunity from the jurisdiction of another country. It allows diplomats safe passage and freedom of travel in a host country and affords almost total protection from local lawsuits and prosecution. Diplomatic immunity is one of the oldest and most widespread practices in international relations; most civilizations since antiquity have granted some degree of special status to foreign envoys and messengers.
International humanitarian lawInternational humanitarian law (IHL), also referred to as the laws of armed conflict, is the law that regulates the conduct of war (jus in bello). It is a branch of international law that seeks to limit the effects of armed conflict by protecting persons who are not participating in hostilities and by restricting and regulating the means and methods of warfare available to combatants. International humanitarian law is inspired by considerations of humanity and the mitigation of human suffering.
Human rightsHuman rights are moral principles or norms for certain standards of human behaviour and are regularly protected in municipal and international law. They are commonly understood as inalienable, fundamental rights "to which a person is inherently entitled simply because she or he is a human being" and which are "inherent in all human beings", regardless of their age, ethnic origin, location, language, religion, ethnicity, or any other status.
Customary lawA legal custom is the established pattern of behavior that can be objectively verified within a particular social setting. A claim can be carried out in defense of "what has always been done and accepted by law". Customary law (also, consuetudinary or unofficial law) exists where: a certain legal practice is observed and the relevant actors consider it to be an opinion of law or necessity (opinio juris). Most customary laws deal with standards of the community that have been long-established in a given locale.
Military occupationMilitary occupation, also known as belligerent occupation or simply occupation, is the effective military control by a ruling power over a territory that is outside of that power's sovereign territory. The territory is then known as the occupied territory and the ruling power the occupant. Occupation is distinguished from annexation and colonialism by its intended temporary duration. While an occupant may set up a formal military government in the occupied territory to facilitate its administration, it is not a necessary precondition for occupation.
Sources of international lawInternational 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.
Non-refoulementNon-refoulement (rəˈfuːlmɒ̃) is a fundamental principle of international law that forbids a country receiving asylum seekers from returning them to a country in which they would be in probable danger of persecution based on "race, religion, nationality, membership of a particular social group or political opinion". Unlike political asylum, which applies to those who can prove a well-grounded fear of persecution based on certain category of persons, non-refoulement refers to the generic repatriation of people, including refugees into war zones and other disaster locales.
Customary international humanitarian lawCustomary international humanitarian law is a body of unwritten rules of public international law, which govern conduct during armed conflict. Customary international law, like international treaty law, is recognized as a primary source of public international law. While international treaties are written agreements by which States establish certain rules, customary international law consists of unwritten rules which derive from “general practice accepted as law”.
Nuremberg principlesThe Nuremberg principles are a set of guidelines for determining what constitutes a war crime. The document was created by the International Law Commission of the United Nations to codify the legal principles underlying the Nuremberg Trials of Nazi party members following World War II. Any person who commits an act which constitutes a crime under international law is responsible therefor and liable to punishment.
