Likasi (formerly official names: Jadotville ( French ) and Jadotstad ( Dutch )) is a city in Haut-Katanga Province , in the south-east of the Democratic Republic of Congo .
164-538: Likasi has a population of around 635,000 (2015). During the 1990s the United Nations set up feeding centres and refugee centres in and around Likasi to assist with the refugees fleeing ethnic violence in Shaba , whose arrival had increased the population of the town some 41,000. Shinkolobwe mine, 20 km west of Likasi (then called Jadotville), was described by a 1943 Manhattan Project intelligence report as
328-631: 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
492-507: 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
656-674: A "systemic failure". In 2010, the organization suffered the worst loss of life in its history, when 101 personnel died in the Haiti earthquake . Acting under the United Nations Security Council Resolution 1973 in 2011, NATO countries intervened in the First Libyan Civil War . The Millennium Summit was held in 2000 to discuss the UN's role in the 21st century. The three-day meeting was
820-895: 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
984-621: A UN official, negotiated an armistice to the resulting conflict , with the Security Council deciding that “an armistice shall be established in all sectors of Palestine”. On 7 November 1956, the first UN peacekeeping force was established to end the Suez Crisis ; however, the UN was unable to intervene against the Soviet Union's simultaneous invasion of Hungary , following the country's revolution . On 14 July 1960,
1148-399: 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 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
1312-535: A centre for industry, especially mining, and is a transport hub for the surrounding region. There are mines and refineries supplied by nearby deposits of copper and cobalt . A $ 17 million crushing plant was installed in nearby Kamatanda that became operational at the start of 2019. The crushed ore is fed to the Heap Leach Unit in Panda , then the copper-containing solution is taken to the electrolysis room at
1476-481: A conference and initialised the drafting of the UN Charter , which was adopted on 25 June 1945. The charter took effect on 24 October 1945, when the UN began operations. The UN's objectives, as outlined by its charter, include maintaining international peace and security, protecting human rights , delivering humanitarian aid , promoting sustainable development , and upholding international law . At its founding,
1640-403: 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
1804-582: 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
SECTION 10
#17327756233791968-496: 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
2132-1013: A myriad of autonomous, separately administered funds, programmes, research and training institutes, and other subsidiary bodies . Each of these entities have their own area of work, governance structure, and budgets such as the World Trade Organization (or the WTO) and the International Atomic Energy Agency (or the IAEA), operate independently of the UN but maintain formal partnership agreements. The UN performs much of its humanitarian work through these institutions, such as preventing famine and malnutrition (the World Food Programme ), protecting vulnerable and displaced people (the UNHCR ), and combating
2296-613: 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
2460-795: 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
2624-433: 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
2788-547: A permanent member to block adoption of a resolution, though not debate. The ten temporary seats are held for two-year terms, with five members elected each year by the General Assembly on a regional basis . The presidency of the Security Council rotates alphabetically each month. The UN Secretariat carries out the day-to-day duties required to operate and maintain the UN system. It is composed of tens of thousands of international civil servants worldwide and headed by
2952-606: A plane crash . Months later he was posthumously awarded the Nobel Peace Prize . In 1964, Hammarskjöld's successor, U Thant , deployed the UN Peacekeeping Force in Cyprus , which would become one of the UN's longest-running peacekeeping missions. With the spread of decolonization in the 1960s, the UN's membership shot up due to an influx of newly independent nations. In 1960 alone, 17 new states joined
3116-610: 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
3280-637: 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
3444-435: 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
SECTION 20
#17327756233793608-546: 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
3772-400: 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
3936-431: 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
4100-414: 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
4264-634: 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
4428-445: A two-thirds majority of those present and voting is required. All other questions are decided by a majority vote. Each member has one vote. Apart from the approval of budgetary matters, resolutions are not binding on the members. The Assembly may make recommendations on any matters within the scope of the UN, except matters of peace and security that are under consideration by the Security Council. Draft resolutions can be forwarded to
4592-504: 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
4756-889: A wide variety of complex tasks. The UN comprises six principal operational organizations: the General Assembly , the Security Council , the Economic and Social Council , the International Court of Justice , the UN Secretariat , and the Trusteeship Council , although the Trusteeship Council has been suspended since 1994. The UN System includes a multitude of specialized agencies , funds, and programmes, including
4920-1033: A wide variety of topics. These include the United Nations Permanent Forum on Indigenous Issues , which advises UN agencies on issues relating to indigenous peoples , the United Nations Forum on Forests , which coordinates and promotes sustainable forest management, the United Nations Statistical Commission , which co-ordinates information-gathering efforts between agencies, and the Commission on Sustainable Development , which co-ordinates efforts between UN agencies and NGOs working towards sustainable development . ECOSOC may also grant consultative status to non-governmental organizations. as of April 2021 almost 5,600 organizations have this status. The UN Charter stipulates that each primary organ of
5084-549: Is a diplomatic and political international organization with the intended purpose of maintaining international peace and security , developing friendly relations among nations, achieving international cooperation, and serving as a center for coordinating the actions of member nations. It is widely recognised as the world's largest international organization. The UN is headquartered in New York City , in international territory with certain privileges extraterritorial to

5248-465: 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
5412-600: 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
5576-452: 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
5740-467: Is defined in the UN Charter as the organization's chief administrative officer. Article 99 of the charter states that the secretary-general can bring to the Security Council's attention "any matter which in their opinion may threaten the maintenance of international peace and security", a phrase that secretaries-general since Trygve Lie have interpreted as giving the position broad scope for action on
5904-581: 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
6068-407: 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
6232-591: 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
6396-627: 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
6560-539: 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
6724-471: 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

6888-578: 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
7052-444: 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
7216-467: 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
7380-428: 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
7544-496: 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,
7708-537: 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. The first known international court
7872-655: The Battle of Mogadishu . The UN mission to Bosnia faced worldwide ridicule for its indecisive and confused mission in the face of ethnic cleansing. In 1994, the UN Assistance Mission for Rwanda failed to intervene in the Rwandan genocide amidst indecision in the Security Council. From the late 1990s to the early 2000s, international interventions authorized by the UN took a wider variety of forms. The United Nations Security Council Resolution 1244 authorised
8036-793: The EFTA Court and the Court of Justice of the Andean Community . 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
8200-528: The Four Power Declaration on General Security which aimed for the creation "at the earliest possible date of a general international organization". This was the first public announcement that a new international organization was being contemplated to replace the League of Nations. The Tehran Conference followed shortly afterwards at which Roosevelt, Churchill and Joseph Stalin , the leader of

On 10 November 1975, a bloc comprising the Soviet Union and Third World nations passed a resolution , over strenuous American and Israeli opposition, declaring Zionism to be a form of racism . The resolution was repealed on 16 December 1991, shortly after the end of the Cold War. With an increasing Third World presence and

#17327756233798528-471: The Hague and Geneva Conventions , the first of which was passed in 1864. 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
8692-625: 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
8856-464: 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
9020-715: 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

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
9512-682: 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

The invasion of Afghanistan in 2001 was overseen by NATO. In 2003, the United States invaded Iraq despite failing to pass a UN Security Council resolution for authorization, prompting a new round of questioning of the UN's effectiveness. Under

On 10 January 1920, the League of Nations formally came into being when the Covenant of the League of Nations , ratified by 42 nations in 1919, took effect. The League Council acted as an executive body directing the Assembly's business. It began with four permanent members—the United Kingdom , France , Italy , and Japan .

11152-458: 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)
11316-568: The 1920s, the League proved ineffective in the 1930s, as it failed to act against the Japanese invasion of Manchuria in 1933. Forty nations voted for Japan to withdraw from Manchuria but Japan voted against it and walked out of the League instead of withdrawing from Manchuria. It also failed to act against the Second Italo-Ethiopian War , after the appeal for international intervention by Ethiopian Emperor Haile Selassie I at Geneva in 1936 went with no avail, including when calls for economic sanctions against Italy failed. Italy and other nations left

While other organs of the UN can only make recommendations to member states, the Security Council has the power to make binding decisions that member states have agreed to carry out, under the terms of Charter Article 25. The decisions of
12300-740: The Greek concept of natural law , the Romans conceived of jus gentium as being universal. 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. Beginning with the Spring and Autumn period of the eighth century BCE, China was divided into numerous states that were often at war with each other. Rules for diplomacy and treaty-making emerged, including notions regarding just grounds for war ,

International law 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.

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

The trains are mostly cargo trains and not passenger trains. Likasi has a humid subtropical climate ( Köppen : Cwa ). 10°59′S 26°44′E / 10.983°S 26.733°E / -10.983; 26.733 United Nations The United Nations ( UN )
13120-563: The Soviet Union, and the signing of the Korean Armistice Agreement on 27 July 1953. On 29 November 1947, the General Assembly approved resolution 181 , a proposal to partition Palestine into two state, with Jerusalem placed under a special international regime. The plan failed and a civil war broke out in Palestine, that led to the creation of the state of Israel afterward. Two years later, Ralph Bunche ,
13284-580: The Soviet Union, before all the issues were resolved. By 1 March 1945, 21 additional states had signed the Declaration by the United Nations. After months of planning, the UN Conference on International Organization opened in San Francisco on 25 April 1945. It was attended by 50 nations' governments and a number of non-governmental organizations. The delegations of the Big Four chaired
13448-649: The Soviet Union, met and discussed the idea of a post-war international organization. The new international organisation was formulated and negotiated amongst the delegations from the Allied Big Four at the Dumbarton Oaks Conference from 21 September to 7 October 1944. They agreed on proposals for the aims, structure and functioning of the new organization. It took the conference at Yalta in February 1945, and further negotiations with
13612-573: The UDHR was drafted, although many countries in the Global South have led the development of human rights on the global stage in the intervening decades. International labour law is generally defined as "the substantive rules of law established at the international level and the procedural rules relating to their adoption and implementation". It operates primarily through the International Labor Organization (ILO),
13776-534: The UN Charter and operate under the UN Human Rights Council , where each global region is represented by elected member states. The Council is responsible for Universal Periodic Review , which requires each UN member state to review its human rights compliance every four years, and for special procedures, including the appointment of special rapporteurs , independent experts and working groups. The treaty-based procedure allows individuals to rely on
13940-444: The UN Charter or international treaties, although in practice there are no relevant matters in the UN Charter. 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
14104-554: The UN authorized a US-led coalition that repulsed Iraq's invasion of Kuwait . Brian Urquhart , the under-secretary-general of the UN from 1971 to 1985, later described the hopes raised by these successes as a "false renaissance" for the organization, given the more troubled missions that followed. Beginning in the last decades of the Cold War , critics of the UN condemned the organization for perceived mismanagement and corruption. In 1984, American President Ronald Reagan withdrew
14268-610: The UN established the United Nations Operation in the Congo (or UNOC), the largest military force of its early decades, to bring order to Katanga , restoring it to the control of the Democratic Republic of the Congo by 11 May 1964. While travelling to meet rebel leader Moise Tshombe during the conflict, Dag Hammarskjöld , often named as one of the UN's most effective secretaries-general, died in
14432-624: The UN had 51 member states ; as of 2024 , it has 193 sovereign states , nearly all of the world's recognized sovereign states. The UN's mission to preserve world peace was complicated in its initial decades due in part to Cold War tensions that existed between the United States and Soviet Union and their respective allies. Its mission has included the provision of primarily unarmed military observers and lightly armed troops charged with primarily monitoring, reporting and confidence-building roles. UN membership grew significantly following
14596-488: The UN itself and operate with almost complete independence from it". These include specialized agencies, research and training institutions, programmes and funds and other UN entities. All organizations in the UN system obey the Noblemaire principle , which calls for salaries that will attract and retain citizens of countries where compensation is highest, and which ensures equal pay for work of equal value regardless of
14760-529: The UN's focus on promoting development, peacekeeping, human rights and global security. The Sustainable Development Goals (or SDGs) were launched in 2015 to succeed the Millennium Development Goals. In addition to addressing global challenges, the UN has sought to improve its accountability and democratic legitimacy by engaging more with civil society and fostering a global constituency. In an effort to enhance transparency, in 2016
14924-465: The UN's primary mandate was peacekeeping , the division between the United States and the Soviet Union often paralysed the organization; generally allowing it to intervene only in conflicts distant from the Cold War . Two notable exceptions were a Security Council resolution on 7 July 1950 authorizing a US-led coalition to repel the North Korean invasion of South Korea , passed in the absence of
15088-582: The UN, 16 of them from Africa. On 25 October 1971, with opposition from the United States, but with the support of many Third World nations, the People's Republic of China was given the Chinese seat on the Security Council in place of the Republic of China (also known as Taiwan). The vote was widely seen as a sign of waning American influence in the organization. Third World nations organized themselves into
15252-636: The United Nations can establish various specialized agencies to fulfill its duties. Specialized agencies are autonomous organizations working with the United Nations and each other through the coordinating machinery of the Economic and Social Council. Each was integrated into the UN system through an agreement with the UN under UN Charter article 57. There are fifteen specialized agencies, which perform functions as diverse as facilitating international travel, preventing and addressing pandemics, and promoting economic development. The United Nations system includes
15416-560: The United States' funding from the United Nations Educational, Scientific and Cultural Organisation (or UNESCO) over allegations of mismanagement, followed by the United Kingdom and Singapore. Boutros Boutros-Ghali , the secretary-general from 1992 to 1996, initiated a reform of the Secretariat, somewhat reducing the size of the organisation. His successor, Kofi Annan , initiated further management reforms in
15580-600: The United States, and the UN has other offices in Geneva , Nairobi , Vienna , and The Hague , where the International Court of Justice is headquartered at the Peace Palace . The UN was established after World War II with the aim of preventing future world wars , and succeeded the League of Nations , which was characterized as being ineffective. On 25 April 1945, 50 nations assembled in San Francisco , California, for
15744-656: The assembly gathers at annual sessions at the General Assembly Hall , but emergency sessions can be summoned. The assembly is led by a president , elected by the member states on a rotating regional basis, and 21 vice-presidents. The first session convened on 10 January 1946 in the Methodist Central Hall in London and comprised representatives of 51 nations. When the General Assembly decides on seminal questions such as those on peace and security, admission of new members and budgetary matters,
15908-529: The basis of the Convention on the Privileges and Immunities of the United Nations , the UN and its agencies are immune from the laws of the countries where they operate, safeguarding the UN's impartiality with regard to host and member countries. Below the six organs are, in the words of the author Linda Fasulo, "an amazing collection of entities and organizations, some of which are actually older than
16072-589: The body's former headquarters in the Peace Palace in The Hague, Netherlands , making it the only principal organ not based in New York City. The ICJ's main function is adjudicating disputes among nations. Examples of issues they have heard include war crimes, violations of state sovereignty and ethnic cleansing. The court can also be called upon by other UN organs to provide advisory opinions on matters of international law. All UN member states are parties to
16236-622: The century prior to the UN's creation, several international organizations such as the International Committee of the Red Cross were formed to ensure protection and assistance for victims of armed conflict and strife. During World War I , several major leaders, especially U.S. President Woodrow Wilson , advocated for a world body to guarantee peace. The winners of the war, the Allies , met to decide on formal peace terms at
16400-627: 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
16564-457: 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
16728-436: 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
16892-452: 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
17056-533: 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
17220-537: The council are known as United Nations Security Council resolutions . The Security Council is made up of fifteen member states: five permanent members (China, France, Russia, the United Kingdom and the United States) and ten non-permanent members (currently Algeria , Ecuador , Guyana , Japan , Malta , Mozambique , the Republic of Korea , Sierra Leone , Slovenia and Switzerland ). The five permanent members hold veto power over UN resolutions, allowing
17384-486: 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
17548-408: 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
17712-831: The eighth secretary-general, Ban Ki-moon , the UN intervened with peacekeepers in crises such as the War in Darfur in Sudan and the Kivu conflict in the Democratic Republic of the Congo and sent observers and chemical weapons inspectors to the Syrian Civil War . In 2013, an internal review of UN actions in the final battles of the Sri Lankan Civil War in 2009 concluded that the organization had suffered
17876-500: The employee's nationality. In practice, the International Civil Service Commission , which governs the conditions of UN personnel, takes reference to the highest-paying national civil service. Staff salaries are subject to an internal tax that is administered by the UN organizations. The General Assembly is the primary deliberative assembly of the UN. Composed of all UN member states ,
18040-436: 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
18204-540: The face of threats from the US to withhold its UN dues. Though the UN Charter had been written primarily to prevent aggression by one nation against another, in the early 1990s the UN faced several simultaneous, serious crises within Somalia, Haiti, Mozambique, and the nations that previously made up Yugoslavia. The UN mission in Somalia was widely viewed as a failure after the United States' withdrawal following casualties in
18368-504: The failure of UN mediation in conflicts in the Middle East , Vietnam , and Kashmir , the UN increasingly shifted its attention to its secondary goals of economic development and cultural exchange. By the 1970s, the UN budget for social and economic development was far greater than its peacekeeping budget. After the Cold War, the UN saw a radical expansion in its peacekeeping duties, taking on more missions in five years than it had in
18532-659: The five principal organs are located at the main UN Headquarters in New York City, while the International Court of Justice is seated in The Hague . Most other major agencies are based in the UN offices at Geneva , Vienna , and Nairobi , and additional UN institutions are located throughout the world. The six official languages of the UN, used in intergovernmental meetings and documents, are Arabic , Chinese , English , French , Russian and Spanish . On
18696-583: 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
18860-751: 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
19024-428: 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
19188-503: 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
19352-481: The largest gathering of world leaders in history, and it culminated in the adoption by all member states of the Millennium Development Goals (or MDGs), a commitment to achieve international development in areas such as poverty reduction , gender equality and public health . Progress towards these goals, which were to be met by 2015, was ultimately uneven. The 2005 World Summit reaffirmed
19516-506: 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
19680-443: 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)
19844-421: 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
20008-654: The most important deposit of uranium yet discovered in the world. The uranium from this mine was used to build the atomic bombs used in Hiroshima and Nagasaki in 1945. In 1961, during the United Nations intervention in the Katanga conflict, a company of Irish UN troops deployed to Jadotville fought valiantly, but was besieged and eventually surrendered to troops loyal to the Katangese Prime Minister Moïse Tshombe . Likasi remains
20172-427: 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
20336-512: 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
20500-400: 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
20664-465: 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
20828-461: The organization are five principal organs established by the UN Charter: the General Assembly , the Security Council , the Economic and Social Council , the International Court of Justice and the UN Secretariat . A sixth principal organ, the Trusteeship Council , suspended its operations on 1 November 1994 upon the independence of Palau ; the last remaining UN trustee territory. Four of
20992-506: The organization held its first public debate between candidates for secretary-general. On 1 January 2017, Portuguese diplomat António Guterres , who had previously served as the UN High Commissioner for Refugees , became the ninth secretary-general. Guterres has highlighted several key goals for his administration, including an emphasis on diplomacy for preventing conflicts, more effective peacekeeping efforts, and streamlining
21156-482: The organization to be more responsive and versatile to international needs. On 13 June 2019, the UN signed a Strategic Partnership Framework with the World Economic Forum in order to "jointly accelerate" the implementation of the 2030 Agenda for Sustainable Development . The United Nations is part of the broader UN System, which includes an extensive network of institutions and entities. Central to
21320-640: 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
21484-475: 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
21648-405: 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
21812-524: The plenary meetings. Previously, Churchill had urged Roosevelt to restore France to its status of a major power after the liberation of Paris in August 1944. The drafting of the Charter of the United Nations was completed over the following two months, and it was signed on 26 June 1945 by the representatives of the 50 countries. The UN officially came into existence on 24 October 1945, upon ratification of
21976-489: The post, but over the years it has become accepted that the position shall be held for one or two terms of five years. The current secretary-general is António Guterres of Portugal, who replaced Ban Ki-moon in 2017. The International Court of Justice (or ICJ), sometimes known as the World Court, is the primary judicial organ of the UN. It is the successor to the Permanent Court of International Justice and occupies
22140-600: The post-war world. At the subsequent meeting of the Inter-Allied Council in London on 24 September 1941, the eight governments in exile of countries under Axis occupation , together with the Soviet Union and representatives of the Free French Forces , unanimously adopted adherence to the common principles of policy set forth by Britain and the United States. Roosevelt and Churchill met at
22304-484: 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
22468-400: 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
22632-440: The presence of Russian troops in Iranian Azerbaijan and British forces in Greece . British diplomat Gladwyn Jebb served as interim secretary-general. The General Assembly selected New York City as the site for the headquarters of the UN. Construction began on 14 September 1948 and the facility was completed on 9 October 1952. The Norwegian Foreign Minister, Trygve Lie , was the first elected UN secretary-general . Though
22796-406: The previous four decades. Between 1988 and 2000, the number of adopted Security Council resolutions more than doubled, and the peacekeeping budget increased by more than tenfold. The UN negotiated an end to the Salvadoran Civil War , launched a successful peacekeeping mission in Namibia , and oversaw democratic elections in post- apartheid South Africa and post- Khmer Rouge Cambodia. In 1991,
22960-417: 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
23124-415: 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
23288-400: 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
23452-420: 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
23616-523: 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,
23780-508: 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
23944-403: 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,
24108-406: 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
24272-502: 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
24436-418: 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
24600-472: 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,
24764-403: 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
24928-434: 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
25092-416: The widespread decolonization in the 1960s. Since then, 80 former colonies have gained independence, including 11 trust territories that had been monitored by the Trusteeship Council . By the 1970s, the UN's budget for economic and social development programmes vastly exceeded its spending on peacekeeping . After the end of the Cold War in 1991, the UN shifted and expanded its field operations, undertaking
25256-404: The world stage. The office has evolved into a dual role of an administrator of the UN organization and a diplomat and mediator addressing disputes between member states and finding consensus to global issues . The secretary-general is appointed by the General Assembly, after being recommended by the Security Council, where the permanent members have veto power. There are no specific criteria for
25420-417: 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
25584-535: 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
25748-567: 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
25912-524: 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.
