International law (also known as public international law and the law of nations ) 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 .
152-640: The Asian–African Legal Consultative Organization ( AALCO ) is an international governmental organization formed in 1956, initially to serve as an advisory board to member states on matters on international law . It was an outgrowth of the Bandung Conference , held in Indonesia during April, 1955, which led to the establishment of the Asian Legal Consultative Committee (ALCC). In April, 1958, it changed its name to
304-631: A national legal system and international law is complex and variable. National law may become international law when treaties permit national jurisdiction to supranational tribunals such as the European Court of Human Rights or the International Criminal Court . Treaties such as the Geneva Conventions require national law to conform to treaty provisions. National laws or constitutions may also provide for
456-507: A "general recognition" by states "whose interests are specially affected". The second element of the test, opinio juris, the belief of a party that a particular action is required by the law is referred to as the subjective element. The ICJ has stated in dictum in North Sea Continental Shelf that, "Not only must the acts concerned amount to a settled practice, but they must also be such, or be carried out in such
608-895: A UN agency with the mission of protecting employment rights which was established in 1919. The ILO has a constitution setting out a number of aims, including regulating work hours and labour supply, protecting workers and children and recognising equal pay and the right to free association, as well as the Declaration of Philadelphia of 1944, which re-defined the purpose of the ILO. The 1998 Declaration on Fundamental Principles and Rights at Work further binds ILO member states to recognise fundamental labour rights including free association, collective bargaining and eliminating forced labour, child labour and employment discrimination. The ILO have also created labour standards which are set out in their conventions and recommendations. Member states then have
760-479: A conflict between territorial government forces and NSAs or NSAs themselves, but also a foreign military intervention against a NSA only if the territorial state consents to such intervention in its territory. Should the intervening country do so without the consent of the territorial state or in support of a NSA against that state, then Common Article 2 applies. For example, the American-led intervention in
912-403: A dispute, determining if a domestic court has jurisdiction and determining whether foreign judgments can be enforced . The first question relates to whether the domestic court or a foreign court is best placed to decide the case. When determining the national law that should apply, the lex causae is the law that has been chosen to govern the case, which is generally foreign, and the lexi fori
1064-567: A fighting function and fights on the State's behalf, a relationship of belonging for the purposes of Article 4A(2) exists." For example, the Viet Cong was under effective control and direction by North Vietnam during the Vietnam War , therefore Common Article 2 solely applied to the conflict. The term protecting power has a specific meaning under these Conventions. A protecting power
1216-582: A local judgment between the same parties. On a global level, the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards was introduced in 1958 to internationalise the enforcement of arbitral awards , although it does not have jurisdiction over court judgments. A state must prove that it has jurisdiction before it can exercise its legal authority. This concept can be divided between prescriptive jurisdiction, which
1368-484: A military command structure. The other Geneva Conventions are not applicable in this situation but only the provisions contained within Article 3, and additionally within the language of Protocol II . The rationale for the limitation is to avoid conflict with the rights of Sovereign States that were not part of the treaties. When the provisions of this article apply, it states that: Persons taking no active part in
1520-668: A much needed update to the Hague Conventions of 1899 and 1907 . In light of these developments, two Protocols were adopted in 1977 that extended the terms of the 1949 Conventions with additional protections. In 2005, a third brief Protocol was added establishing an additional protective sign for medical services, the Red Crystal , as an alternative to the ubiquitous Red Cross and Red Crescent emblems, for those countries that find them objectionable. The Geneva Conventions of 12 August 1949. Commentary ( The Commentaries )
1672-496: A multilateral treaty. Where a treaty does not have provisions allowing for termination or withdrawal, such as the Genocide Convention, it is prohibited unless the right was implied into the treaty or the parties had intended to allow for it. A treaty can also be held invalid, including where parties act ultra vires or negligently, where execution has been obtained through fraudulent, corrupt or forceful means, or where
SECTION 10
#17327800012311824-613: A number of countries began to distinguish between acta jure gestionis , commercial actions, and acta jure imperii , government actions; the restrictive theory of immunity said states were immune where they were acting in a governmental capacity but not a commercial one. The European Convention on State Immunity in 1972 and the UN Convention on Jurisdictional Immunities of States and their Property attempt to restrict immunity in accordance with customary law. Historically individuals have not been seen as entities in international law, as
1976-795: A number of treaties focused on environmental protection were ratified, including the Declaration of the United Nations Conference on the Human Environment of 1972, the World Charter for Nature of 1982, and the Vienna Convention for the Protection of the Ozone Layer of 1985. States generally agreed to co-operate with each other in relation to environmental law, as codified by principle 24 of
2128-433: A particular legal circumstance. Historically the comity theory has been used although the definition is unclear, sometimes referring to reciprocity and sometimes being used as a synonym for private international law. Story distinguished it from "any absolute paramount obligation, superseding all discretion on the subject". There are three aspects to conflict of laws – determining which domestic court has jurisdiction over
2280-610: A range of entities, including the Church , mercantile city-states, and kingdoms, most of which had overlapping and ever-changing jurisdictions. As in China and India, these divisions prompted the development of rules aimed at providing stable and predictable relations. Early examples include canon law , which governed ecclesiastical institutions and clergy throughout Europe; the lex mercatoria ("merchant law"), which concerned trade and commerce; and various codes of maritime law , such as
2432-637: A special status. The rules in a treaty can only be considered national law if the contents of the treaty have been enacted first. An example is the United Kingdom; after the country ratified the European Convention on Human Rights , the convention was only considered to have the force of law in national law after Parliament passed the Human Rights Act 1998 . In practice, the division of countries between monism and dualism
2584-435: A starting point but does not recognise that organisations can have no separate personality but nevertheless function as an international organisation. The UN Economic and Social Council has emphasised a split between inter-government organisations (IGOs), which are created by inter-governmental agreements, and international non-governmental organisations (INGOs). All international organisations have members; generally this
2736-546: A state and res communis which is territory that cannot be acquired by a state. There have historically been five methods of acquiring territorial sovereignty , reflecting Roman property law: occupation, accretion, cession , conquest and prescription . The law of the sea is the area of international law concerning the principles and rules by which states and other entities interact in maritime matters. It encompasses areas and issues such as navigational rights, sea mineral rights, and coastal waters jurisdiction. The law of
2888-400: A state and, separately, it may recognise that nation's government as being legitimate and capable of representing the state on the international stage. There are two theories on recognition; the declaratory theory sees recognition as commenting on a current state of law which has been separately satisfied whereas the constitutive theory states that recognition by other states determines whether
3040-431: A state can be considered to have legal personality. States can be recognised explicitly through a released statement or tacitly through conducting official relations, although some countries have formally interacted without conferring recognition. Throughout the 19th century and the majority of the 20th century, states were protected by absolute immunity, so they could not face criminal prosecution for any actions. However
3192-414: A treaty "shall be interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose". This represents a compromise between three theories of interpretation: the textual approach which looks to the ordinary meaning of the text, the subjective approach which considers factors such as the drafters' intention, and
SECTION 20
#17327800012313344-634: A treaty but such violations, particularly of peremptory norms , can be met with disapproval by others and in some cases coercive action ranging from diplomatic and economic sanctions to war. The sources of international law include international custom (general state practice accepted as law), treaties , and general principles of law recognised by most national legal systems. Although international law may also be reflected in international comity —the practices adopted by states to maintain good relations and mutual recognition—such traditions are not legally binding . The relationship and interaction between
3496-416: A trial unless the allegation of a war crime has been made. According to article 43 of the 1949 Conventions, soldiers are employed for the purpose of serving in war; engaging in armed conflict is legitimate, and does not constitute a grave breach. Should a soldier be arrested by belligerent forces, they are to be considered "lawful combatants" and afforded the protectorate status of a prisoner of war (POW) until
3648-504: A way, as to be evidence of a belief that this practice is rendered obligatory by the existence of a rule of law requiring it". A committee of the International Law Association has argued that there is a general presumption of an opinio juris where state practice is proven but it may be necessary if the practice suggests that the states did not believe it was creating a precedent. The test in these circumstances
3800-681: Is a series of four volumes of books published between 1952 and 1958 and containing commentaries to each of the four Geneva Conventions. The series was edited by Jean Pictet who was the vice-president of the International Committee of the Red Cross . The Commentaries are often relied upon to provide authoritative interpretation of the articles. The Geneva Conventions are rules that apply only in times of armed conflict and seek to protect people who are not or are no longer taking part in hostilities. The first convention dealt with
3952-455: Is a state that is not taking part in the armed conflict, but that has agreed to look after the interests of a state that is a party to the conflict. The protecting power is a mediator enabling the flow of communication between the parties to the conflict. The protecting power also monitors the implementation of these Conventions, such as by visiting the zone of conflict and prisoners of war. The protecting power must act as an advocate for prisoners,
4104-465: Is also able to issue a conditional declaration stating that it will consent to a given treaty only on the condition of a particular provision or interpretation. Article 54 of the VCLT provides that either party may terminate or withdraw from a treaty in accordance with its terms or at any time with the consent of the other party, with 'termination' applying to a bilateral treaty and 'withdrawal' applying to
4256-600: Is claiming rights under refugee law but as, argued by the political theorist Hannah Arendt , human rights are often tied to someone's nationality. The European Court of Human Rights allows individuals to petition the court where their rights have been violated and national courts have not intervened and the Inter-American Court of Human Rights and the African Court on Human and Peoples' Rights have similar powers. Traditionally, sovereign states and
4408-452: Is considered the seminal event in international law. The resulting Westphalian sovereignty is said to have established the current international legal order characterised by independent nation states , which have equal sovereignty regardless of their size and power, defined primarily by non-interference in the domestic affairs of sovereign states, although historians have challenged this narrative. The idea of nationalism further solidified
4560-629: Is defined under Article 1 of the Montevideo Convention on the Rights and Duties of States as a legal person with a permanent population, a defined territory, government and capacity to enter relations with other states. There is no requirement on population size, allowing micro-states such as San Marino and Monaco to be admitted to the UN, and no requirement of fully defined boundaries, allowing Israel to be admitted despite border disputes . There
4712-407: Is no academic consensus about what is included within this scope. They are considered to be derived from both national and international legal systems, although including the latter category has led to debate about potential cross-over with international customary law. The relationship of general principles to treaties or custom has generally been considered to be "fill[ing] the gaps" although there

4864-591: Is often more complicated; countries following both approaches may accept peremptory norms as being automatically binding and they may approach treaties, particularly later amendments or clarifications, differently than they would approach customary law. Many countries with older or unwritten constitutions do not have explicit provision for international law in their domestic system and there has been an upswing in support for monism principles in relation to human rights and humanitarian law, as most principles governing these concepts can be found in international law. A state
5016-627: Is restricted to states, although it can include other international organisations. Sometimes non-members will be allowed to participate in meetings as observers. The Yearbook of International Organizations sets out a list of international organisations, which include the UN, the WTO, the World Bank and the IMF. Generally organisations consist of a plenary organ, where member states can be represented and heard; an executive organ, to decide matters within
5168-484: Is still no conclusion about their exact relationship in the absence of a hierarchy. A treaty is defined in Article 2 of the Vienna Convention on the Law of Treaties (VCLT) as "an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation". The definition specifies that
5320-471: Is the territorial principle , which states that a nation has jurisdiction over actions which occur within its territorial boundaries. The second is the nationality principle , also known as the active personality principle, whereby a nation has jurisdiction over actions committed by its nationals regardless of where they occur. The third is the passive personality principle, which gives a country jurisdiction over any actions which harm its nationals. The fourth
5472-578: Is the authority of a legislature to enact legislation on a particular issue, and adjudicative jurisdiction, which is the authority of a court to hear a particular case. This aspect of private international law should first be resolved by reference to domestic law, which may incorporate international treaties or other supranational legal concepts, although there are consistent international norms. There are five forms of jurisdiction which are consistently recognised in international law; an individual or act can be subject to multiple forms of jurisdiction. The first
5624-444: Is the national law of the court making the determination. Some examples are lex domicilii , the law of the domicile, and les patriae , the law of the nationality. The rules which are applied to conflict of laws will vary depending on the national system determining the question. There have been attempts to codify an international standard to unify the rules so differences in national law cannot lead to inconsistencies, such as through
5776-467: Is the protective principle, where a nation has jurisdiction in relation to threats to its "fundamental national interests". The final form is universal jurisdiction , where a country has jurisdiction over certain acts based on the nature of the crime itself. Following World War II, the modern system for international human rights was developed to make states responsible for their human rights violations. The UN Economic and Security Council established
5928-428: Is whether opinio juris can be proven by the states' failure to protest. Other academics believe that intention to create customary law can be shown by states including the principle in multiple bilateral and multilateral treaties, so that treaty law is necessary to form customs. The adoption of the VCLT in 1969 established the concept of jus cogens , or peremptory norms, which are "a norm accepted and recognized by
6080-496: Is widely regarded as the father of international law, being one of the first scholars to articulate an international order that consists of a "society of states" governed not by force or warfare but by actual laws, mutual agreements, and customs. Grotius secularised international law; his 1625 work, De Jure Belli ac Pacis , laid down a system of principles of natural law that bind all nations regardless of local custom or law. He inspired two nascent schools of international law,
6232-537: The "Uniting for Peace" resolution of 3 November 1950, which allowed the organ to pass recommendations to authorize the use of force. This resolution also led to the practice of UN peacekeeping , which has been notably been used in East Timor and Kosovo . There are more than one hundred international courts in the global community, although states have generally been reluctant to allow their sovereignty to be limited in this way.

On February 7, 2002, President Bush adopted the view that Common Article 3 did not protect al Qaeda prisoners because the United States-al Qaeda conflict was "not of an international character." The Supreme Court of the United States invalidated the Bush Administration view of Common Article 3, in Hamdan v. Rumsfeld , by ruling that Common Article Three of

Interstate arbitration can also be used to resolve disputes between states, leading in 1899 to the creation of the Permanent Court of Arbitration which facilitates the process by maintaining a list of arbitrators. This process was used in the Island of Palmas case and to resolve disputes during the Eritrean-Ethiopian war . The ICJ operates as one of

Colonial expansion by European powers reached its peak in the late 19th century and its influence began to wane following the unprecedented bloodshed of World War I , which spurred the creation of international organisations. Right of conquest was generally recognized as international law before World War II . The League of Nations
6992-625: The Hague Convention on the Recognition and Enforcement of Foreign Judgments in Civil and Commercial Matters and the Brussels Regulations . These treaties codified practice on the enforcement of international judgments, stating that a foreign judgment would be automatically recognised and enforceable where required in the jurisdiction where the party resides, unless the judgement was contrary to public order or conflicted with
7144-464: The Hobbesian notion that the state of nature was one of war and conflict, arguing that the natural state of the world is actually peaceful but weak and uncertain without adherence to the law of nations. The actions of a state consist of nothing more than the sum of the individuals within that state, thereby requiring the state to apply a fundamental law of reason, which is the basis of natural law. He
7296-715: The Holy See were the sole subjects of international law. With the proliferation of international organisations over the last century, they have also been recognised as relevant parties. One definition of international organisations comes from the ILC's 2011 Draft Articles on the Responsibility of International Organizations which in Article 2(a) states that it is "an organization established by treaty or other instrument governed by international law and possessing its own international legal personality". This definition functions as
7448-465: The Indian subcontinent was divided into various states, which over time developed rules of neutrality, treaty law , and international conduct, and established both temporary and permanent embassies . Following the collapse of the western Roman Empire in the fifth century CE, Europe fragmented into numerous often-warring states for much of the next five centuries. Political power was dispersed across
7600-682: The International Bank for Reconstruction and Development (World Bank) to the World Health Organization furthered the development of a multilateralist approach as states chose to compromise on sovereignty to benefit from international cooperation. Since the 1980s, there has been an increasing focus on the phenomenon of globalisation and on protecting human rights on the global scale, particularly when minorities or indigenous communities are involved, as concerns are raised that globalisation may be increasing inequality in

Despite these, and other, multilateral environmental agreements covering specific issues, there is no overarching policy on international environmental protection or one specific international organisation, with the exception of the UN Environmental Programme . Instead, a general treaty setting out the framework for tackling an issue has then been supplemented by more specific protocols. Climate change has been one of

While non-state armed groups are automatically presumed to engage in NIACs, they also can cross into
8360-775: The Syrian civil war . The lines between combatants and civilians have blurred when the actors are not exclusively High Contracting Parties (HCP). Since the fall of the Soviet Union , an HCP often is faced with a non-state actor, as argued by General Wesley Clark in 2007. Examples of such conflict include the Sri Lankan Civil War , the Sudanese Civil War , and the Colombian Armed Conflict , as well as most military engagements of

Two further human rights treaties were adopted by the UN in 1966, the International Covenant on Civil and Political Rights (ICCPR) and
8664-459: The biological and chemical warfare in international armed conflicts is addressed by the 1925 Geneva Protocol . The Swiss businessman Henry Dunant went to visit wounded soldiers after the Battle of Solferino in 1859. He was shocked by the lack of facilities, personnel, and medical aid available to help these soldiers. As a result, he published his book, A Memory of Solferino , in 1862, on

To this end, the following acts are and shall remain prohibited at any time and in any place whatsoever with respect to
8968-458: The "law of nations", which unlike its eponymous Roman predecessor, applied natural law to relations between states. In Islam, a similar framework was developed wherein the law of nations was derived, in part, from the principles and rules set forth in treaties with non-Muslims. The 15th century witnessed a confluence of factors that contributed to an accelerated development of international law. Italian jurist Bartolus de Saxoferrato (1313–1357)

However, in contrast to modern international law, the Roman law of nations applied to relations with and between foreign individuals rather than among political units such as states.

Rules for diplomacy and treaty-making emerged, including notions regarding just grounds for war ,

There has been legal debate on this topic with the only prominent view on the length of time necessary to establish custom explained by Humphrey Waldock as varying "according to the nature of the case". The practice is not required to be followed universally by states, but there must be

Alexander , claimed
10336-505: The Syrian civil war became both an IAC with Syria and a NIAC with the Islamic State because the U.S. intervened in Syrian territory without the former's consent. On the other hand, Russia intervened in Syrian territory against the Free Syrian Army upon invitation by Syria, making Russia's participation subject only to Common Article 3 and therefore Protocol II (which Russia ratified on September 29, 1989). The U.S.-led NATO invasion of Afghanistan from October 7 to December 17, 2001

The ICJ may also be asked by an international organisation to provide an advisory opinion on a legal question, which are generally considered non-binding but authoritative. Conflict of laws , also known as private international law, was originally concerned with choice of law , determining which nation's laws should govern
10944-556: The US since 2000. Some scholars hold that Common Article 3 deals with these situations, supplemented by Protocol II (1977). These set out minimum legal standards that must be followed for internal conflicts. International tribunals, particularly the International Criminal Tribunal for the former Yugoslavia (ICTY), have clarified international law in this area. In the 1999 Prosecutor v. Dusko Tadic judgement,

Representatives of 12 states and kingdoms signed the convention: For both of these accomplishments, Henry Dunant became co recipient of
11248-615: The above-mentioned persons: During the negotiation of the Geneva Conventions, France and Britain were initially staunchly opposed to Common Article 3. However, to save face during negotiations and make strategic concessions, France and Britain deliberately introduced ambiguous language in the text of Common Article 3 that made it easy for states to avoid the obligations of the rule. As a consequence, Common Article 3 only concerns with humane treatment and does not deal with methods and means of hostilities, such as bombings committed by non-state armed groups or state forces against civilian targets in
11400-508: The agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners , civilians and military personnel ; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone. The Geneva Conventions define
11552-532: The beginning of the Cold War era, leading many to believe that the 1949 Geneva Conventions were addressing a largely extinct reality: on the one hand, most armed conflicts had become internal, or civil wars, while on the other, most wars had become increasingly asymmetric . Modern armed conflicts were inflicting an increasingly higher toll on civilians, which brought the need to provide civilian persons and objects with tangible protections in time of combat, bringing
11704-450: The cessation of the conflict. Human rights law applies to any incarcerated individual, including the right to a fair trial. Charges may only be brought against an enemy POW after a fair trial, but the initial crime being accused must be an explicit violation of the accords, more severe than simply fighting against the captor in battle. No trial will otherwise be afforded to a captured soldier, as deemed by human rights law. This element of
11856-416: The characteristics of war, whether carried out within the confines of one country or not. There are two criteria to distinguish non-international armed conflicts from lower forms of violence. The level of violence has to be of certain intensity, for example when the state cannot contain the situation with regular police forces. Also, involved non-state groups need to have a certain level of organization, like
12008-627: The choice as to whether or not to ratify and implement these standards. The secretariat of the ILO is the International Labour Office, which can be consulted by states to determine the meaning of a convention, which forms the ILO's case law. Although the Right to Organise Convention does not provide an explicit right to strike, this has been interpreted into the treaty through case law. The UN does not specifically focus on international labour law, although some of its treaties cover
12160-457: The common consent of these states" and this definition has been largely adopted by international legal scholars. There is a distinction between public and private international law ; the latter is concerned with whether national courts can claim jurisdiction over cases with a foreign element and the application of foreign judgments in domestic law, whereas public international law covers rules with an international origin. The difference between
12312-617: The competence of the organisation; and an administrative organ, to execute the decisions of the other organs and handle secretarial duties. International organisations will typically provide for their privileges and immunity in relation to its member states in their constitutional documents or in multilateral agreements, such as the Convention on the Privileges and Immunities of the United Nations . These organisations also have
12464-452: The concept and formation of nation-states. Elements of the naturalist and positivist schools were synthesised, notably by German philosopher Christian Wolff (1679–1754) and Swiss jurist Emer de Vattel (1714–1767), both of whom sought a middle-ground approach. During the 18th century, the positivist tradition gained broader acceptance, although the concept of natural rights remained influential in international politics, particularly through
12616-628: The conduct of arbitration. Its Centers provide the opportunities for training of arbitrators as well. The Directors of the Centres, who are from amongst lawyers familiar to arbitration, are appointed by suggestion of the host governments and ratification of the Secretary-General of AALCO . Directors of the Centres present their reports on the functioning of the Centres at the Annual Sessions of AALCO. The current membership includes
12768-533: The conduct of warfare during the American Civil War , and is noted for codifying rules and articles of war adhered to by nations across the world, including the United Kingdom, Prussia, Serbia and Argentina. In the years that followed, numerous other treaties and bodies were created to regulate the conduct of states towards one another, including the Permanent Court of Arbitration in 1899, and
12920-414: The convention has been confused during past incidents of detainment of US soldiers by North Vietnam, where the regime attempted to try all imprisoned soldiers in court for committing grave breaches, on the incorrect assumption that their sole existence as enemies of the state violated international law. Although warfare has changed dramatically since the Geneva Conventions of 1949, they are still considered
13072-718: The cornerstone of contemporary international humanitarian law . They protect combatants who find themselves hors de combat , and they protect civilians caught up in the zone of war. These treaties came into play for all recent non-international armed conflicts, including the War in Afghanistan , the Iraq War , the invasion of Chechnya (1994–2017) , and the Russo-Georgian War . The Geneva Conventions also protect those affected by non-international armed conflicts such as
13224-524: The creation, interpretation and application of the laws of armed conflict. The complexity of these new challenges, as well as the speed in which they are developed, complicates the application of the Conventions, which have not been updated in a long time. Adding to this challenge is the very slow speed of the procedure of developing new treaties to deal with new forms of warfare, and determining agreed-upon interpretations to existing ones, meaning that by
13376-580: The deficiencies in the protection of prisoners of war under the Hague Conventions of 1899 and 1907 . The "Convention relative to the Treatment of Prisoners of War" was not to replace these earlier conventions signed at The Hague; rather it supplemented them. There was considerable debate over whether the Geneva Convention should prohibit indiscriminate forms of warfare, such as aerial bombings, nuclear bombings and starvation, but no agreement
13528-486: The determination of rules of law". It was originally considered that the arrangement of the sources sequentially would suggest an implicit hierarchy of sources; however, the statute does not provide for a hierarchy and other academics have argued that therefore the sources must be equivalent. General principles of law have been defined in the Statute as "general principles of law recognized by civilized nations" but there
13680-408: The efficiency of the procedures themselves. Legal territory can be divided into four categories. There is territorial sovereignty which covers land and territorial sea, including the airspace above it and the subsoil below it, territory outside the sovereignty of any state, res nullius which is not yet within territorial sovereignty but is territory that is legally capable of being acquired by
13832-579: The enforcement of grave breaches when the United Nations Security Council asserts its authority and jurisdiction from the UN Charter to apply universal jurisdiction. The UNSC did this when they established the International Criminal Tribunal for Rwanda and the International Criminal Tribunal for the former Yugoslavia to investigate and/or prosecute alleged violations. Soldiers, as prisoners of war, will not receive
13984-436: The exception of states who have been persistent objectors during the process of the custom being formed and special or local forms of customary law. The requirement for state practice relates to the practice, either through action or failure to act, of states in relation to other states or international organisations. There is no legal requirement for state practice to be uniform or for the practice to be long-running, although
14136-604: The first Nobel Peace Prize in 1901. On 20 October 1868 the first unsuccessful attempt to expand the 1864 treaty was undertaken. With the 'Additional Articles relating to the Condition of the Wounded in War' an attempt was initiated to clarify some rules of the 1864 convention and to extend them to maritime warfare. The Articles were signed but were only ratified by the Netherlands and the United States of America. The Netherlands later withdrew their ratification. The protection of
14288-507: The first time, the 1864 convention. It remained in force until 1970 when Costa Rica acceded to the 1949 Geneva Conventions. The 1929 conference yielded two conventions that were signed on 27 July 1929. One, the " Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field ", was the third version to replace the original convention of 1864. The other was adopted after experiences in World War I had shown
14440-511: The focus was on the relationship between states. As human rights have become more important on the global stage, being codified by the UN General Assembly (UNGA) in the Universal Declaration of Human Rights in 1948, individuals have been given the power to defend their rights to judicial bodies. International law is largely silent on the issue of nationality law with the exception of cases of dual nationality or where someone
14592-399: The following members, with founding members marked with an asterisk (*): International law International law differs from state-based domestic legal systems in that it operates largely through consent , since there is no universally accepted authority to enforce it upon sovereign states . States and non-state actors may choose to not abide by international law, and even to breach
14744-433: The following: Nations that are party to these treaties must enact and enforce legislation penalizing any of these crimes. Nations are also obligated to search for persons alleged to commit these crimes, or persons having ordered them to be committed , and to bring them to trial regardless of their nationality and regardless of the place where the crimes took place. The principle of universal jurisdiction also applies to
14896-513: The full protections of the Conventions are considered to apply. This article states that the certain minimum rules of war apply to armed conflicts "not of an international character." The International Committee of the Red Cross has explained that this language describes non-international armed conflict (NIAC) "where at least one Party is not a State." For example, it would apply to conflicts between state forces and non-state actors (NSAs), or between two NSAs, or to other conflicts that have all
15048-564: The horrors of war. His wartime experiences inspired Dunant to propose: The former proposal led to the establishment of the Red Cross in Geneva . The latter led to the 1864 Geneva Convention , the first codified international treaty that covered the sick and wounded soldiers on the battlefield. On 22 August 1864, the Swiss government invited the governments of all European countries, as well as
15200-751: The implementation or integration of international legal obligations into domestic law. The modern term "international law" was originally coined by Jeremy Bentham in his 1789 book Introduction to the Principles of Morals and Legislation to replace the older law of nations, a direct translation of the late medieval concepts of ius gentium , used by Hugo Grotius , and droits des gens , used by Emer de Vattel . The definition of international law has been debated; Bentham referred specifically to relationships between states which has been criticised for its narrow scope. Lassa Oppenheim defined it in his treatise as "a law between sovereign and equal states based on
15352-428: The international community of States as a whole as a norm from which no derogation is permitted and which can be modified only by a subsequent norm of general international law having the same character". Where customary or treaty law conflicts with a peremptory norm, it will be considered invalid, but there is no agreed definition of jus cogens . Academics have debated what principles are considered peremptory norms but
15504-574: The international legal system. The sources of international law applied by the community of nations are listed in Article 38(1) of the Statute of the International Court of Justice , which is considered authoritative in this regard. These categories are, in order, international treaties , customary international law , general legal principles and judicial decisions and the teachings of prominent legal scholars as "a subsidiary means for
15656-409: The invocation of the Geneva Conventions "as a basis for a private right of action." "... Common Article 3 continues the conventional practice (reflected in both the 'Lieber' and 'The Hague' provisions) of according humanitarian protections only to 'belligerents' who defer to the laws and customs of war : not to 'insurrectionists' who defy these norms from the very outset of hostilities. Observance of
15808-506: The law of war and towards the domains such as the law of the sea and commercial treaties. The positivist school grew more popular as it reflected accepted views of state sovereignty and was consistent with the empiricist approach to philosophy that was then gaining acceptance in Europe. The developments of the 17th century culminated at the conclusion of the Peace of Westphalia in 1648, which
15960-443: The laws of war and treaties. Francisco de Vitoria (1486–1546), who was concerned with the treatment of indigenous peoples by Spain, invoked the law of nations as a basis for their innate dignity and rights, articulating an early version of sovereign equality between peoples. Francisco Suárez (1548–1617) emphasised that international law was founded upon natural law and human positive law. Dutch jurist Hugo Grotius (1583–1645)
16112-421: The most important and heavily debated topics in recent environmental law. The United Nations Framework Convention on Climate Change , intended to set out a framework for the mitigation of greenhouse gases and responses to resulting environmental changes, was introduced in 1992 and came into force two years later. As of 2023, 198 states were a party. Separate protocols have been introduced through conferences of
16264-476: The mostly widely agreed is the principle of non-use of force. The next year, the ICJ defined erga omnes obligations as those owed to "the international community as a whole", which included the illegality of genocide and human rights. There are generally two approaches to the relationship between international and national law, namely monism and dualism. Monism assumes that international and national law are part of
16416-512: The nation state, although some academics emphasise that it is distinct from either type of law. It was defined by Philip Jessup as "all law which regulates actions or events that transcend national frontiers". A more recent concept is supranational law , which was described in a 1969 paper as "[a] relatively new word in the vocabulary of politics". Systems of supranational law arise when nations explicitly cede their right to make decisions to this system's judiciary and legislature, which then have
16568-400: The naturalists and the positivists. In the former camp was German jurist Samuel von Pufendorf (1632–1694), who stressed the supremacy of the law of nature over states. His 1672 work, Of the Law of Nature and Nations, expanded on the theories of Grotius and grounded natural law to reason and the secular world, asserting that it regulated only external acts of states. Pufendorf challenged
16720-465: The nine primary human rights treaties: The regional human rights enforcement systems operate in Europe, Africa and the Americas through the European Court of Human Rights , the Inter-American Court of Human Rights and the African Court on Human and Peoples' Rights . International human rights has faced criticism for its Western focus, as many countries were subject to colonial rule at the time that
16872-640: The parties , including the Kyoto Protocol which was introduced in 1997 to set specific targets for greenhouse gas reduction and the 2015 Paris Agreement which set the goal of keeping global warming at least below 2 °C (3.6 °F) above pre-industrial levels. Individuals and organisations have some rights under international environmental law as the Aarhus Convention in 1998 set obligations on states to provide information and allow public input on these issues. However few disputes under
17024-475: The parties must be states, however international organisations are also considered to have the capacity to enter treaties. Treaties are binding through the principle of pacta sunt servanda , which allows states to create legal obligations on themselves through consent. The treaty must be governed by international law; however it will likely be interpreted by national courts. The VCLT, which codifies several bedrock principles of treaty interpretation, holds that
17176-405: The parties must sign to indicate acceptance of the wording but there is no requirement on a state to later ratify the treaty, although they may still be subject to certain obligations. When signing or ratifying a treaty, a state can make a unilateral statement to negate or amend certain legal provisions which can have one of three effects: the reserving state is bound by the treaty but the effects of
17328-484: The power to enter treaties, using the Vienna Convention on the Law of Treaties between States and International Organizations or between International Organizations as a basis although it is not yet in force. They may also have the right to bring legal claims against states depending, as set out in Reparation for Injuries , where they have legal personality and the right to do so in their constitution. The UNSC has
17480-459: The power under Chapter VII of the UN Charter to take decisive and binding actions against states committing "a threat to the peace, breach of the peace, or an act of aggression" for collective security although prior to 1990, it has only intervened once, in the case of Korea in 1950. This power can only be exercised, however, where a majority of member states vote for it, as well as receiving
17632-571: The power, as Commander in Chief of the Armed Forces, to determine that any person, including an American citizen, who is suspected of being a member, agent, or associate of Al Qaeda , the Taliban , or possibly any other terrorist organization, is an "enemy combatant" who can be detained in U.S. military custody until hostilities end, pursuant to the international law of war. The application of
17784-647: The prohibition of fake insignia is listed at Article 39.2, but the law is silent on the complete absence of insignia. The status of POWs captured in this circumstance remains a question. Educational institutions and organizations including Harvard University , the International Committee of the Red Cross , and the Rohr Jewish Learning Institute use the Geneva Convention as a primary text investigating torture and warfare. Artificial intelligence and autonomous weapon systems, such as military robots and cyber-weapons, are creating challenges in
17936-417: The regimes set out in environmental agreements are referred to the ICJ, as the agreements tend to specify their compliance procedures. These procedures generally focus on encouraging the state to once again become compliant through recommendations but there is still uncertainty on how these procedures should operate and efforts have been made to regulate these processes although some worry that this will undercut
18088-415: The relevant provisions are precluded or changes, the reserving state is bound by the treaty but not the relevant provisions, or the reserving state is not bound by the treaty. An interpretive declaration is a separate process, where a state issues a unilateral statement to specify or clarify a treaty provision. This can affect the interpretation of the treaty but it is generally not legally binding. A state
18240-459: The republican revolutions of the United States and France. Until the mid-19th century, relations between states were dictated mostly by treaties, agreements between states to behave in a certain way, unenforceable except by force, and nonbinding except as matters of honour and faithfulness. One of the first instruments of modern armed conflict law was the Lieber Code of 1863, which governed
18392-483: The right to make laws that are directly effective in each member state. This has been described as "a level of international integration beyond mere intergovernmentalism yet still short of a federal system". The most common example of a supranational system is the European Union . With origins tracing back to antiquity , states have a long history of negotiating interstate agreements. An initial framework
18544-524: The rights and protections afforded to those non-combatants who fulfill the criteria of being protected persons . The treaties of 1949 were ratified, in their entirety or with reservations , by 196 countries . The Geneva Conventions concern only protected non-combatants in war. The use of wartime conventional weapons is addressed by the Hague Conventions of 1899 and 1907 and the 1980 Convention on Certain Conventional Weapons , while
18696-586: The rights of neutral parties, and the consolidation and partition of states; these concepts were sometimes applied to relations with barbarians along China's western periphery beyond the Central Plains . The subsequent Warring States period saw the development of two major schools of thought, Confucianism and Legalism , both of which held that the domestic and international legal spheres were closely interlinked, and sought to establish competing normative principles to guide foreign relations. Similarly,
18848-414: The rules of warfare is what elevates an 'insurrectionist' to the legally cognizable status of 'belligerent' under the 'International law of war'; nothing short of such an 'observance' suffices to effect this transformation from the infra legal to legal ." Whether the conflict is an IAC or a NIAC or both depends on the nature and circumstances of the situation. Since there is a general prohibition against
19000-508: The same legal order. Therefore, a treaty can directly become part of national law without the need for enacting legislation, although they will generally need to be approved by the legislature. Once approved, the content of the treaty is considered as a law that has a higher status than national laws. Examples of countries with a monism approach are France and the Netherlands. The dualism approach considers that national and international law are two separate legal orders, so treaties are not granted
19152-403: The same topics. Many of the primary human rights conventions also form part of international labour law, providing protection in employment and against discrimination on the grounds of gender and race. It has been claimed that there is no concept of discrete international environmental law , with the general principles of international law instead being applied to these issues. Since the 1960s,
19304-862: The sea was primarily composed of customary law until the 20th century, beginning with the League of Nations Codification Conference in 1930, the UN Conference on the Law of the Sea and the adoption of the UNCLOS in 1982. The UNCLOS was particularly notable for making international courts and tribunals responsible for the law of the sea. Geneva Conventions The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war . The singular term Geneva Convention colloquially denotes
19456-711: The sessions and the work of the General Assembly and maintaining a permanent office at Headquarters. In 2014, the AALCO established an Informal Expert Group on Customary International Law. That group adopted a set of comments on the work of the International Law Commission on identification of customary international law. Those comments and the report of the AALCO Special Rapporteur Sienho Yee are published on
19608-478: The sick and wounded. During the European Middle Ages , international law was concerned primarily with the purpose and legitimacy of war, seeking to determine what constituted "just war ". The Greco-Roman concept of natural law was combined with religious principles by Jewish philosopher Maimonides (1135–1204) and Christian theologian Thomas Aquinas (1225–1274) to create the new discipline of
19760-554: The six organs of the UN, based out of the Hague with a panel of fifteen permanent judges. It has jurisdiction to hear cases involving states but cannot get involved in disputes involving individuals or international organizations. The states that can bring cases must be party to the Statute of the ICJ , although in practice most states are UN members and would therefore be eligible. The court has jurisdiction over all cases that are referred to it and all matters specifically referred to in
19912-520: The support of the permanent five members of the UNSC. This can be followed up with economic sanctions, military action, and similar uses of force. The UNSC also has a wide discretion under Article 24, which grants "primary responsibility" for issues of international peace and security. The UNGA, concerned during the Cold War with the requirement that the USSR would have to authorise any UNSC action, adopted
20064-472: The teleological approach which interprets a treaty according to its objective and purpose. A state must express its consent to be bound by a treaty through signature, exchange of instruments, ratification, acceptance, approval or accession. Accession refers to a state choosing to become party to a treaty that it is unable to sign, such as when establishing a regional body. Where a treaty states that it will be enacted through ratification, acceptance or approval,
20216-531: The threshold of an IAC. The 2020 ICRC commentary on the Third Geneva Convention requires two elements for this classification: "the group must in fact fight on behalf of that Party" and "that Party must accept both the fighting role of the group and the fact that the fighting is done on its behalf." It further states that "[w]here a Party to a conflict has overall control over the militia , volunteer corps or organized resistance movement that has
20368-473: The treatment of wounded and sick armed forces in the field. The second convention dealt with the sick, wounded, and shipwrecked members of armed forces at sea. The third convention dealt with the treatment of prisoners of war during times of conflict. The fourth convention dealt with the treatment of civilians and their protection during wartime. Individuals who fulfill the criteria of protected persons in international armed conflicts are protected by
20520-403: The treaty contradicts peremptory norms. Customary international law requires two elements: a consistent practice of states and the conviction of those states that the consistent practice is required by a legal obligation, referred to as opinio juris . Custom distinguishes itself from treaty law as it is binding on all states, regardless of whether they have participated in the practice, with
20672-434: The two areas of law has been debated as scholars disagree about the nature of their relationship. Joseph Story , who originated the term "private international law", emphasised that it must be governed by the principles of public international law but other academics view them as separate bodies of law. Another term, transnational law, is sometimes used to refer to a body of both national and international rules that transcend
20824-534: The use of force between States (as is reflected within article 2(4) of the United Nations Charter ) with respect to Common Article 2, it is generally presumed that any use of such military force which is governed by international humanitarian law (IHL) is attributable to deliberate belligerent intent. Regarding Common Article 3, the ICRC in its 2016 commentary stated the provision includes not just
20976-409: The victims of maritime warfare would later be realized by the third Hague Convention of 1899 and the tenth Hague Convention of 1907 . In 1906 thirty-five states attended a conference convened by the Swiss government. On 6 July 1906 it resulted in the adoption of the "Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field", which improved and supplemented, for
21128-519: The website of the AALCO. One of the major achievements of AALCO in its programme in the economic field was the launching of its Integrated Scheme for Settlement of Disputes in the Economic and Commercial Transactions in 1978. Pursuant to that Scheme, it was decided to establish Regional Arbitration Centres under the auspices of AALCO, which would function as international institutions with the objectives to promote international commercial arbitration in
21280-651: The whole is referred to as the "Geneva Conventions of 1949" or simply the "Geneva Conventions". Usually only the Geneva Conventions of 1949 are referred to as First, Second, Third or Fourth Geneva Conventions. The treaties of 1949 were ratified, in whole or with reservations , by 196 countries . The 1949 conventions have been modified with three amendment protocols : The Geneva Conventions apply at times of war and armed conflict to governments who have ratified its terms. The details of applicability are spelled out in Common Articles 2 and 3. This article states that
21432-468: The world, from the eastern Mediterranean to East Asia . In Ancient Greece , many early peace treaties were negotiated between its city-states and, occasionally, with neighbouring states. The Roman Empire established an early conceptual framework for international law, jus gentium , which governed the status of foreigners living in Rome and relations between foreigners and Roman citizens . Adopting
21584-541: The wounded, and civilians. Not all violations of the treaty are treated equally. The most serious crimes are termed grave breaches and provide a legal definition of a war crime . Grave breaches of the Third and Fourth Geneva Conventions include the following acts if committed against a person specifically protected by the conventions: Also considered grave breaches of the Fourth Geneva Convention are
21736-590: Was among the earliest scholars to expand international law beyond European Christian nations, advocating for its application and recognition among all peoples on the basis of shared humanity. In contrast, positivist writers, such as Richard Zouche (1590–1661) in England and Cornelis van Bynkershoek (1673–1743) in the Netherlands, argued that international law should derive from the actual practice of states rather than Christian or Greco-Roman sources. The study of international law shifted away from its core concern on
21888-567: Was based on the division of the world into three categories: the dar al-Islam , where Islamic law prevailed; the dar al-sulh , non-Islamic realms that concluded an armistice with a Muslim government; and the dar al-harb , non-Islamic lands which were contested through jihad . Islamic legal principles concerning military conduct served as precursors to modern international humanitarian law and institutionalised limitations on military conduct, including guidelines for commencing war, distinguishing between civilians and combatants and caring for
22040-757: Was conceptualised by the Ancient Romans and this idea of ius gentium has been used by various academics to establish the modern concept of international law. Among the earliest recorded examples are peace treaties between the Mesopotamian city-states of Lagash and Umma (approximately 3100 BCE), and an agreement between the Egyptian pharaoh , Ramesses II , and the Hittite king , Ḫattušili III , concluded in 1279 BCE. Interstate pacts and agreements were negotiated and agreed upon by polities across
22192-476: Was considered the founder of private international law . Another Italian jurist, Baldus de Ubaldis (1327–1400), provided commentaries and compilations of Roman, ecclesiastical, and feudal law , creating an organised source of law that could be referenced by different nations. Alberico Gentili (1552–1608) took a secular view to international law, authoring various books on issues in international law, notably Law of War , which provided comprehensive commentary on
22344-559: Was established in 1947 to develop and codify international law. In the 1940s through the 1970s, the dissolution of the Soviet bloc and decolonisation across the world resulted in the establishment of scores of newly independent states. As these former colonies became their own states, they adopted European views of international law. A flurry of institutions, ranging from the International Monetary Fund (IMF) and
22496-666: Was founded to safeguard peace and security. International law began to incorporate notions such as self-determination and human rights . The United Nations (UN) was established in 1945 to replace the League, with an aim of maintaining collective security. A more robust international legal order followed, buttressed by institutions such as the International Court of Justice (ICJ) and the UN Security Council (UNSC). The International Law Commission (ILC)
22648-596: Was initially an IAC because it waged war against the Islamic Emirate of Afghanistan under Taliban rule. Once the new Karzai administration was established and recognized internationally, the conflict changed from an IAC to a NIAC, with NATO troops under International Security Assistance Force (ISAF) and Resolute Support Mission (RSM) auspices assisting the Islamic Republic of Afghanistan with its consent in battling Taliban insurgents. In contrast,
22800-470: Was originally an intention that a state must have self-determination , but now the requirement is for a stable political environment. The final requirement of being able to enter relations is commonly evidenced by independence and sovereignty. Under the principle of par in parem non habet imperium , all states are sovereign and equal, but state recognition often plays a significant role in political conceptions. A country may recognise another nation as
22952-566: Was reached on those forms of violence. Inspired by the wave of humanitarian and pacifistic enthusiasm following World War II and the outrage towards the war crimes disclosed by the Nuremberg and Tokyo trials , a series of conferences were held in 1949 reaffirming, expanding and updating the prior Geneva and Hague Conventions. It yielded four distinct conventions: Despite the length of these documents, they were found over time to be incomplete. The nature of armed conflicts had changed with
23104-557: Was the Central American Court of Justice , prior to World War I, when the Permanent Court of International Justice (PCIJ) was established. The PCIJ was replaced by the ICJ, which is the best known international court due to its universal scope in relation to geographical jurisdiction and subject matter . There are additionally a number of regional courts, including the Court of Justice of the European Union ,
