International courts are formed by treaties between nations , or by an international organization such as the United Nations – and include ad hoc tribunals and permanent institutions but exclude any courts arising purely under national authority.
134-576: The International Court of Justice ( ICJ ; French: Cour internationale de justice , CIJ ), or colloquially the World Court , is the only international court that adjudicates general disputes between nations, and gives advisory opinions on international legal issues. It is one of the six organs of the United Nations (UN), and is located in The Hague, Netherlands . The ICJ
268-523: A Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
402-645: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
536-592: A grenade at the Archduke's car and injured two of his aides. The other assassins were also unsuccessful. An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
670-540: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
804-808: A candidate, and British judge Sir Christopher Greenwood being withdrawn as a candidate for election for a second nine-year term on the bench in 2017, leaving no judges from the United Kingdom on the court. Greenwood had been supported by the UN Security Council but failed to get a majority in the UN General Assembly. Indian judge Dalveer Bhandari took the seat instead. Article 6 of the Statute provides that all judges should be "elected regardless of their nationality among persons of high moral character" who are either qualified for
938-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1072-613: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
1206-471: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,
1340-588: A general international organization, based on the principle of the sovereign equality of all peace-loving States, and open to membership by all such States, large and small, for the maintenance of international peace and security". The following Allied conference at Dumbarton Oaks , in the United States, published a proposal in October 1944 that called for the establishment of an intergovernmental organization that would include an international court. A meeting
1474-682: A marked reluctance on the part of a majority of the court to become involved in a dispute in such a way as to bring it potentially into conflict with the Council. The court stated in the Nicaragua case that there is no necessary inconsistency between action by the Security Council and adjudication by the ICJ. However, when there is room for conflict, the balance appears to be in favour of the Security Council. Should either party fail "to perform

#17327656015731608-548: A possibility. This was accentuated by British and Russian support for France against Germany during the 1911 Agadir Crisis . German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
1742-621: A principal organ of the new United Nations. The statute of this court would form an integral part of the United Nations Charter , which, to maintain continuity, expressly held that the Statute of the International Court of Justice (ICJ) was based upon that of the PCIJ. Consequently, the PCIJ convened for the last time in October 1945 and resolved to transfer its archives to its successor, which would take its place at
1876-405: A professional nature." In addition, Article 17 requires that judges do not show any prior biases on cases before them, specifically, "No member may participate in the decision of any case in which he has previously taken part as agent, counsel, or advocate for one of the parties, or as a member of a national or international court, or of a commission of enquiry, or in any other capacity." Judges of
2010-526: A request, the court decides which states and organizations might provide useful information and gives them an opportunity to present written or oral statements. Advisory opinions were intended as a means by which UN agencies could seek the court's help in deciding complex legal issues that might fall under their respective mandates. In principle, the court's advisory opinions are only consultative in character but they are influential and widely respected. Certain instruments or regulations can provide in advance that
2144-834: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and
2278-516: A significant escalation, ending any chance of Austria cooperating with Russia in the Balkans, while also damaging diplomatic relations between Serbia and Italy. Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
2412-424: A state knows that it will have a judicial officer who can participate in deliberation and offer other judges local knowledge and an understanding of the state's perspective, it may be more willing to submit to the jurisdiction of the court. Although this system does not sit well with the judicial nature of the body, it is usually of little practical consequence. Ad hoc judges usually (but not always) vote in favour of
2546-416: A state may bring a case on behalf of one of its nationals or corporations, such as in matters concerning diplomatic protection. Jurisdiction is often a crucial question for the court in contentious cases. The key principle is that the ICJ has jurisdiction only on the basis of consent. Under Article 36, there are four foundations for the court's jurisdiction: Additionally, the court may have jurisdiction on
2680-577: A unanimous vote of the other members of the court. Despite these provisions, the independence of ICJ judges has been questioned. For example, during the Nicaragua case , the United States issued a communiqué suggesting that it could not present sensitive material to the court because of the presence of judges from the Soviet bloc. Judges may deliver joint judgments or give their own separate opinions. Decisions and advisory opinions are by majority, and, in
2814-478: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
SECTION 20
#17327656015732948-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as
3082-455: A whole, the Somme offensive led to an estimated 420,000 British casualties, along with 200,000 French and 500,000 Germans. The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across
3216-490: Is an international organization , or a body of an international organization, that hears cases in which one party may be a state or international organization (or body thereof), and which is composed of independent judges who follow predetermined rules of procedure to issue binding decisions on the basis of international law . Early examples of international courts include the Nuremberg and Tokyo tribunals established in
3350-508: Is known, however, that from 1908 to 1913, military spending by the six major European powers increased by over 50% in real terms. The years before 1914 were marked by a series of crises in the Balkans, as other powers sought to benefit from the Ottoman decline. While Pan-Slavic and Orthodox Russia considered itself the protector of Serbia and other Slav states, they preferred the strategically vital Bosporus straits to be controlled by
3484-710: Is the successor of the Permanent Court of International Justice (PCIJ), which was established in 1920 by the League of Nations . After the Second World War , the League and the PCIJ were replaced by the United Nations and ICJ, respectively. The Statute of the ICJ , which sets forth its purpose and structure, draws heavily from that of its predecessor, whose decisions remain valid. All member states of
3618-574: The Schutzkorps was established, and carried out the persecution of Serbs. The assassination initiated the July Crisis, a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain. Believing that Serbian intelligence helped organise Franz Ferdinand's murder, Austrian officials wanted to use the opportunity to end their interference in Bosnia and saw war as
3752-641: The World War . In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of
3886-893: The Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and the Middle East , as well as in parts of Africa and the Asia-Pacific , and in Europe was characterised by trench warfare ; the widespread use of artillery , machine guns, and chemical weapons (gas); and the introductions of tanks and aircraft . World War I was one of the deadliest conflicts in history , resulting in an estimated 10 million military dead and more than 20 million wounded , plus some 10 million civilian dead from causes including genocide . The movement of large numbers of people

Japan declared war on Germany before seizing territories in the Pacific, which later became the South Seas Mandate , as well as German Treaty ports on
4154-663: The International Criminal Tribunal for Rwanda that deals with the genocide in Rwanda . In addition to international tribunals created to address crimes committed during genocides and civil war, ad hoc courts and tribunals combining international and domestic strategies have also been established on a situational basis. Examples of these "hybrid tribunals" are the Special Court for Sierra Leone , Special Tribunal for Lebanon , Special Panels of

4288-721: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,
4422-596: The UN Security Council from a list of people nominated by the national groups in the Permanent Court of Arbitration . The election process is set out in Articles 4–19 of the ICJ Statute. Elections are staggered, with five judges elected every three years to ensure continuity within the court. Should a judge die in office, the practice has generally been to elect a judge in a special election to complete
4556-828: The United States entered the war on the Allied side following Germany's resumption of unrestricted submarine warfare against Atlantic shipping. Later that year, the Bolsheviks seized power in the Russian October Revolution , and Soviet Russia signed an armistice with the Central Powers in December, followed by a separate peace in March 1918. That month, Germany launched an offensive in
4690-487: The hydrophone and depth charges were introduced, destroyers could potentially successfully attack a submerged submarine. Convoys slowed the flow of supplies since ships had to wait as convoys were assembled; the solution was an extensive program of building new freighters. Troopships were too fast for the submarines and did not travel the North Atlantic in convoys. The U-boats sunk more than 5,000 Allied ships, at
4824-821: The tank . After the First Battle of the Marne in September 1914, Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the " Race to the Sea ". By the end of 1914, the opposing forces confronted each other along an uninterrupted line of entrenched positions from the Channel to the Swiss border. Since the Germans were normally able to choose where to stand, they generally held
4958-588: The 1839 Treaty of London did not require it to oppose a German invasion with military force; however, Prime Minister Asquith and his senior Cabinet ministers were already committed to supporting France, the Royal Navy had been mobilised, and public opinion was strongly in favour of intervention. On 31 July, Britain sent notes to Germany and France, asking them to respect Belgian neutrality; France pledged to do so, but Germany did not reply. Aware of German plans to attack through Belgium, French Commander-in-Chief Joseph Joffre asked his government for permission to cross
5092-563: The 1879 Dual Alliance , which became the Triple Alliance when Italy joined in 1882. For Bismarck, the purpose of these agreements was to isolate France by ensuring the three Empires resolve any disputes between themselves. In 1887, Bismarck set up the Reinsurance Treaty , a secret agreement between Germany and Russia to remain neutral if either were attacked by France or Austria-Hungary. For Bismarck, peace with Russia
5226-441: The 1913 Treaty of London , which had created an independent Albania while enlarging the territories of Bulgaria, Serbia, Montenegro and Greece. However, disputes between the victors sparked the 33-day Second Balkan War , when Bulgaria attacked Serbia and Greece on 16 June 1913; it was defeated, losing most of Macedonia to Serbia and Greece, and Southern Dobruja to Romania. The result was that even countries which benefited from
5360-569: The Austrians and Serbs clashed at the battles of the Cer and Kolubara ; over the next two weeks, Austrian attacks were repulsed with heavy losses. As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
5494-646: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in

5628-553: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,
5762-404: The Central Powers. However, the pro-German King Constantine I dismissed the pro-Allied government of Eleftherios Venizelos before the Allied expeditionary force arrived. The Macedonian front was at first mostly static. French and Serbian forces retook limited areas of Macedonia by recapturing Bitola on 19 November 1916 following the costly Monastir offensive , which brought stabilisation of

After Vienna refused to withdraw its cruiser SMS Kaiserin Elisabeth from Tsingtao, Japan declared war on Austria-Hungary, and the ship was sunk in November 1914. Within a few months, Allied forces had seized all German territories in the Pacific, leaving only isolated commerce raiders and a few holdouts in New Guinea. Some of the first clashes of

Judges and high-level staff of such courts may be afforded diplomatic immunity if their governing authority allows. First World War World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions:
6164-430: The First World War led to the creation of the League of Nations , established by the Paris Peace Conference of 1919 as the first worldwide intergovernmental organization aimed at maintaining peace and collective security. Article 14 League's Covenant called for the establishment of a Permanent Court of International Justice (PCIJ), which would be responsible for adjudicating any international dispute submitted to it by
6298-427: The General Assembly or the Security Council the power to request the court to issue an advisory opinion on any legal question. Organs of the UN other than the General Assembly or the Security Council require the General Assembly's authorization to request an advisory opinion of the ICJ. These organs of the UN only request an advisory opinion regarding the matters that fall within the scope of their activities. On receiving
6432-548: The German High Seas Fleet was confined to port. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond
6566-465: The German Army increased in size from 1908 to 1914, he changed the allocation of forces between the two wings to 70:30. He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in
6700-462: The German right wing would sweep through the Netherlands and Belgium , then swing south, encircling Paris and trapping the French army against the Swiss border. The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke
6834-426: The Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As

#17327656015736968-439: The ICJ and the Security Council , and the separation of their powers, was considered by the court in 1992 in the Pan Am case . The court had to consider an application from Libya for the order of provisional measures of protection to safeguard its rights, which, it alleged, were being infringed by the threat of economic sanctions by the United Kingdom and United States. The problem was that these sanctions had been authorized by
7102-491: The ICJ, the PCIJ was not part of the league, nor were members of the league automatically a party to its Statute. The United States, which played a key role in both the second Hague Peace Conference and the Paris Peace Conference, was notably not a member of the league. However, several of its nationals served as judges of the court. From its first session in 1922 until 1940, the PCIJ dealt with 29 interstate disputes and issued 27 advisory opinions. The court's widespread acceptance
7236-438: The International Court of Justice , similar to that of its predecessor, is the main constitutional document constituting and regulating the court. The court's workload covers a wide range of judicial activity. After the court ruled that the United States 's covert war against Nicaragua was in violation of international law ( Nicaragua v. United States ), the United States withdrew from compulsory jurisdiction in 1986 to accept
7370-404: The International Court of Justice , the court's rulings and opinions are binding on the parties with respect to the particular case ruled on by the court. The first permanent institution established for the purpose of settling international disputes was the Permanent Court of Arbitration (PCA), which was created by the Hague Peace Conference of 1899. Initiated by the Russian Tsar Nicholas II ,
7504-512: The International Court of Justice are entitled to the style of His/Her Excellency. Judges are not able to hold any other post or act as counsel. In practice, members of the court have their own interpretation of these rules and many have chosen to remain involved in outside arbitration and hold professional posts as long as there is no conflict of interest. Former judge Bruno Simma and current judge Georg Nolte have acknowledged that moonlighting should be restricted. A judge can be dismissed only by
7638-565: The Middle East. In all, 140,000 soldiers served on the Western Front and nearly 700,000 in the Middle East, with 47,746 killed and 65,126 wounded. The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed
7772-545: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,

The Serbian capture of ports on the Adriatic resulted in partial Austrian mobilisation, starting on 21 November 1912, including units along the Russian border in Galicia . The Russian government decided not to mobilise in response, unprepared to precipitate a war. The Great Powers sought to re-assert control through
8040-408: The Peace Palace. The judges of the PCIJ all resigned on 31 January 1946, with the election of the first members of the ICJ taking place the following February at the First Session of the United Nations General Assembly and Security Council . In April 1946, the PCIJ was formally dissolved, and the ICJ, in its first meeting, was elected President José Gustavo Guerrero of El Salvador, who had served as
8174-549: The Russian Stavka agreed with the French to attack Germany within fifteen days of mobilisation, ten days before the Germans had anticipated, although it meant the two Russian armies that entered East Prussia on 17 August did so without many of their support elements. By the end of 1914, German troops held strong defensive positions inside France, controlled the bulk of France's domestic coalfields, and inflicted 230,000 more casualties than it lost itself. However, communications problems and questionable command decisions cost Germany

#17327656015738308-414: The Security Council, which resulted in a potential conflict between the Chapter VII functions of the Security Council and the judicial function of the court. The court decided, by eleven votes to five, that it could not order the requested provisional measures because the rights claimed by Libya, even if legitimate under the 1971 Montreal Convention , could not be prima facie regarded as appropriate since
8442-429: The Serbian retreat toward the Adriatic coast in the Battle of Mojkovac on 6–7 January 1916, but ultimately the Austrians also conquered Montenegro. The surviving Serbian soldiers were evacuated to Greece. After the conquest, Serbia was divided between Austro-Hungary and Bulgaria. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure its government to declare war against
8576-421: The UN are party to the ICJ Statute and may initiate contentious legal cases ; however, advisory proceedings may be submitted only by certain UN organs and agencies . The ICJ consists of a panel of 15 judges elected by the UN General Assembly and Security Council for nine-year terms. No more than one judge of each nationality may be represented on court at the same time, and judges collectively must reflect
8710-455: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
8844-430: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
8978-399: The action was ordered by the Security Council. In accordance with Article 103 of the UN Charter, obligations under the Charter took precedence over other treaty obligations. Nevertheless, the court declared the application admissible in 1998. A decision on the merits has not been given since the parties (United Kingdom, United States, and Libya) settled the case out of court in 2003. There was
9112-421: The advisory opinion shall be specifically binding on particular agencies or states, but inherently they are non-binding under the Statute of the court. This non-binding character does not mean that advisory opinions are without legal effect, because the legal reasoning embodied in them reflects the court's authoritative views on important issues of international law. In arriving at them, the court follows essentially
9246-443: The aftermath of World War II . Several such international courts are presently located in The Hague in the Netherlands , most importantly the International Court of Justice (ICJ), and the International Criminal Court (ICC). Further international courts exist elsewhere, usually with their jurisdiction restricted to a particular country, a global or regional intergovernmental or supranational organisation, or historic issue, such as
9380-446: The aggressor, German Chancellor Bethmann Hollweg delayed the commencement of war preparations until 31 July. That afternoon, the Russian government were handed a note requiring them to "cease all war measures against Germany and Austria-Hungary" within 12 hours. A further German demand for neutrality was refused by the French who ordered general mobilization but delayed declaring war. The German General Staff had long assumed they faced
9514-407: The attack by the Austro-Hungarian army under Mackensen's army of 250,000 that was already underway. Serbia was conquered in a little more than a month, as the Central Powers, now including Bulgaria, sent in 600,000 troops in total. The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
9648-416: The basis of tacit consent ( forum prorogatum ). In the absence of clear jurisdiction under Article 36, jurisdiction is established if the respondent accepts ICJ jurisdiction explicitly or simply pleads on the merits . This arose in the 1949 Corfu Channel Case (U.K. v. Albania), in which the court held that a letter from Albania stating that it submitted to the jurisdiction of the ICJ was sufficient to grant
9782-556: The bench. In 2023, judges elected to take office from 2024 did not include a Russian member, so for the first time, from 2024 there will be no member from the Commonwealth of Independent States . This is also the first time that Russia would not have a judge on the ICJ, even going back to its predecessor, the Soviet Union. Article 31 of the statute sets out a procedure whereby ad hoc judges sit on contentious cases before
9916-543: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
10050-536: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war. On 2 August, Germany occupied Luxembourg and exchanged fire with French units when German patrols entered French territory; on 3 August, they declared war on France and demanded free passage across Belgium, which
10184-600: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,
10318-649: The capital of the recently annexed Bosnia and Herzegovina . Cvjetko Popović , Gavrilo Princip , Nedeljko Čabrinović , Trifko Grabež , Vaso Čubrilović ( Bosnian Serbs ) and Muhamed Mehmedbašić (from the Bosniaks community), from the movement known as Young Bosnia , took up positions along the Archduke's motorcade route, to assassinate him. Supplied with arms by extremists within the Serbian Black Hand intelligence organisation, they hoped his death would free Bosnia from Austrian rule. Čabrinović threw
10452-463: The case unless the court appointed judges to the chamber acceptable to the parties. Judgments of chambers may have either less authority than full Court judgments or diminish the proper interpretation of universal international law informed by a variety of cultural and legal perspectives. On the other hand, the use of chambers might encourage greater recourse to the court and thus enhance international dispute resolution . As of 6 February 2024,
10586-466: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,
10720-601: The composition of the court is as follows: As stated in Article 93 of the UN Charter, all 193 UN members are automatically parties to the court's statute. Non-UN members may also become parties to the court's statute under the Article 93(2) procedure, which was used by Switzerland in 1948 and Nauru in 1988, prior to either joining the UN. Once a state is a party to the court's statute, it is entitled to participate in cases before
10854-537: The conference involved all the world's major powers, as well as several smaller states, and resulted in the first multilateral treaties concerned with the conduct of warfare. Among these was the Convention for the Pacific Settlement of International Disputes , which set forth the institutional and procedural framework for arbitral proceedings, which would take place in The Hague, Netherlands . Although
10988-502: The contesting parties, as well as to provide an advisory opinion upon any dispute or question referred to it by the League of Nations. In December 1920, following several drafts and debates, the Assembly of the league unanimously adopted the statute of the PCIJ, which was signed and ratified the following year by a majority of members. Among other things, the new Statute resolved the contentious issues of selecting judges by providing that
11122-470: The convention and enhanced the rules governing arbitral proceedings before the PCA. During this conference, the United States, Great Britain and Germany submitted a joint proposal for a permanent court whose judges would serve full-time. As the delegates could not agree how the judges would be selected, the matter was shelved pending an agreement to be adopted at a later convention. The Hague Peace Conferences, and
11256-520: The cost of 199 submarines. World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
11390-413: The court derives from the Article 41 of its Statute. Similar to the final judgment, the order for interim measures of the court are binding on state parties to the dispute. The ICJ has competence to indicate interim measures only if the prima facie jurisdiction is satisfied. An advisory opinion is a function of the court open only to specified United Nations bodies and agencies. The UN Charter grants
11524-504: The court jurisdiction. Until rendering a final judgment, the court has competence to order interim measures for the protection of the rights of a party to a dispute. One or both parties to a dispute may apply the ICJ for issuing interim measures. In the Frontier Dispute Case, both parties to the dispute, Burkina Faso and Mali , submitted an application to the court to indicate interim measures. Incidental jurisdiction of
11658-562: The court's decision before the Security Council. Furthermore, if the Security Council refuses to enforce a judgment against any other state, there is no method of forcing the state to comply. Furthermore, the most effective form to take action for the Security Council, coercive action under Chapter VII of the United Nations Charter , can be justified only if international peace and security are at stake. The Security Council has never done that so far. The relationship between
11792-736: The court's history, the five permanent members of the United Nations Security Council (France, USSR, China, the United Kingdom, and the United States) have always had a judge serving, thereby occupying three of the Western seats, one of the Asian seats and one of the Eastern European seats. Exceptions have been China not having a judge on the court from 1967 to 1985, during which time it did not put forward
11926-602: The court's judgment that called on the US to "cease and to refrain" from the "unlawful use of force" against the government of Nicaragua. The court ruled (with only the American judge dissenting) that the United States was "in breach of its obligation under the Treaty of Friendship with Nicaragua not to use force against Nicaragua" and ordered the United States to pay war reparations . International court An international court
12060-487: The court's jurisdiction only on a discretionary basis. Chapter XIV of the United Nations Charter authorizes the UN Security Council to enforce Court rulings. However, such enforcement is subject to the veto power of the five permanent members of the council, which the United States used in the Nicaragua case. The ICJ is composed of fifteen judges elected to nine-year terms by the UN General Assembly and
12194-432: The court. However, being a party to the statute does not automatically give the court jurisdiction over disputes involving those parties. The issue of jurisdiction is considered in the three types of ICJ cases: contentious issues, incidental jurisdiction, and advisory opinions. In contentious cases (adversarial proceedings seeking to settle a dispute), the ICJ produces a binding ruling between states that agree to submit to
12328-433: The court. The system allows any party to a contentious case (if it otherwise does not have one of that party's nationals sitting on the court) to select one additional person to sit as a judge on that case only. It is thus possible that as many as seventeen judges may sit on one case. The system may seem strange when compared with domestic court processes, but its purpose is to encourage states to submit cases. For example, if
12462-522: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
12596-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
12730-965: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as
12864-683: The event of an equal division, the president's vote becomes decisive, which occurred in the Legality of the Use by a State of Nuclear Weapons in Armed Conflict (Opinion requested by WHO), [1996] ICJ Reports 66. Judges may also deliver separate dissenting opinions. In its 77 years of history, only five women have been elected to the Court, with former UN Special Rapporteur Philip Alston calling for states to take seriously questions of representation in
12998-590: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany. After the 1877–1878 Russo-Turkish War , the League was dissolved due to Austrian concerns over the expansion of Russian influence in the Balkans , an area they considered to be of vital strategic interest. Germany and Austria-Hungary then formed
13132-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
13266-465: The formation of ad hoc chambers to hear particular disputes. In 1993, a special chamber was established, under Article 26(1) of the ICJ statute, to deal specifically with environmental matters (although it has never been used). Ad hoc chambers are more frequently convened. For example, chambers were used to hear the Gulf of Maine Case (Canada/US). In that case, the parties made clear they would withdraw
13400-595: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
13534-542: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage. One of the most successful was the SMS ; Emden , part of the German East Asia Squadron stationed at Qingdao , which seized or sank 15 merchantmen, a Russian cruiser and a French destroyer. Most of the squadron
13668-549: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
13802-500: The highest judicial office in their home states or known as lawyers with sufficient competence in international law. Judicial independence is dealt with specifically in Articles 16–18. To insure impartiality, Article 16 of the Charter requires independence from their national governments or other interested parties, stating, "No member of the Court may exercise any political or administrative function, or engage in any other occupation of
13936-516: The ideas that emerged therefrom, influenced the creation of the Central American Court of Justice , which was established in 1908 as one of the earliest regional judicial bodies. Various plans and proposals were made between 1911 and 1919 for the establishment of an international judicial tribunal, which would not be realized in the formation of a new international system following the First World War . The unprecedented bloodshed of
14070-470: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade . Russia ordered general mobilization in support of Serbia on 30 July. Anxious to ensure backing from the SPD political opposition by presenting Russia as
14204-435: The issue may be taken before the Security Council for enforcement action. There are obvious problems with such a method of enforcement. If the judgment is against one of the five permanent members of the Security Council or its allies, any resolution on enforcement could then be vetoed by that member. That occurred, for example, after the Nicaragua case , when Nicaragua brought the issue of the United States' noncompliance with
14338-551: The judges be elected by both the council and the Assembly of the league concurrently but independently. The makeup of the PCIJ would reflect the "main forms of civilization and the principal legal systems of the world". The PCIJ would be permanently placed at the Peace Palace in The Hague, alongside Permanent Court of Arbitration. The PCIJ represented a major innovation in international jurisprudence in several ways: Unlike
14472-624: The last president of the PCIJ. The court also appointed members of its Registry, mainly drawn from that of the PCIJ, and held an inaugural public sitting later that month. The first case was submitted in May 1947 by the United Kingdom against Albania concerning incidents in the Corfu Channel . Established in 1945 by the UN Charter , the court began work in 1946 as the successor to the Permanent Court of International Justice . The Statute of
14606-439: The obligations incumbent upon it under a judgment rendered by the Court", the Security Council may be called upon to "make recommendations or decide upon measures" if the Security Council deems such actions necessary. In practice, the court's powers have been limited by the unwillingness of the losing party to abide by the court's ruling and by the Security Council's unwillingness to impose consequences. However, in theory, "so far as
14740-465: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
14874-483: The parties to the case are concerned, a judgment of the Court is binding, final and without appeal", and "by signing the Charter, a State Member of the United Nations undertakes to comply with any decision of the International Court of Justice in a case to which it is a party." For example, the United States had previously accepted the court's compulsory jurisdiction upon its creation in 1946 but in 1984, after Nicaragua v. United States , withdrew its acceptance following
15008-450: The precise meaning of "main forms of civilization" is contested. There is an informal understanding that the seats will be distributed by geographic regions so that there are five seats for Western countries, three for African states (including one judge of Francophone civil law, one of Anglophone common law and one Arab), two for Eastern European states, three for Asian states and two for Latin American and Caribbean states. For most of
15142-524: The principal civilizations and legal systems of the world. Seated in the Peace Palace in The Hague , Netherlands, the ICJ is the only principal UN organ not located in New York City . Its official working languages are English and French. Since the entry of its first case on 22 May 1947, the ICJ has entertained 191 cases through 13 November 2023. Pursuant to Article 59 of the Statute of
15276-427: The proceedings would be supported by a permanent bureau—whose functions would be equivalent to that of a secretariat or court registry—the arbitrators would be appointed by the disputing states from a larger pool provided by each member of the convention. The PCA was established in 1900 and began proceedings in 1902. A second Hague Peace Conference in 1907, which involved most of the world's sovereign states , revised
15410-738: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. The U-boat threat lessened in 1917, when merchant ships began travelling in convoys , escorted by destroyers . This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after
15544-417: The ruling of the court. Only states may be parties in contentious cases; individuals, corporations, component parts of a federal state, NGOs, UN organs, and self-determination groups are excluded from direct participation, although the court may receive information from public international organizations . However, this does not preclude non-state interests from being the subject of proceedings; for example,
15678-401: The same rules and procedures that govern its binding judgments delivered in contentious cases submitted to it by sovereign states. An advisory opinion derives its status and authority from the fact that it is the official pronouncement of the principal judicial organ of the United Nations. Advisory opinions have often been controversial because the questions asked are controversial or the case
15812-399: The state that appointed them and thus cancel each other out. Generally, the court sits as full bench, but in the last fifteen years, it has on occasion sat as a chamber. Articles 26–29 of the statute allow the court to form smaller chambers, usually 3 or 5 judges, to hear cases. Two types of chambers are contemplated by Article 26: firstly, chambers for special categories of cases, and second,
15946-469: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "There is no doubt that the course and character of the feared 'European War' ... will become the first world war in the full sense of the word." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
16080-509: The term. Historically, deceased judges have been replaced by judges from the same region, though not —as often wrongly asserted— necessarily from the same nationality. Article 3 states that no two judges may be nationals of the same country. According to Article 9, the membership of the court is supposed to represent the "main forms of civilization and of the principal legal systems of the world". This has been interpreted to include common law , civil law , socialist law , and Islamic law , while
16214-691: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
16348-631: The two-thirds majority in the Senate required for a treaty. Following a peak of activity in 1933, the PCIJ began to decline in its activities due to the growing international tension and isolationism that characterized the era. The Second World War effectively put an end to the court, which held its last public session in December 1939 and issued its last orders in February 1940. In 1942 the United States and United Kingdom jointly declared support for establishing or re-establishing an international court after
16482-645: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
16616-601: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
16750-503: The war, and in 1943, the U.K. chaired a panel of jurists from around the world, the "Inter-Allied Committee", to discuss the matter. Its 1944 report recommended that: Several months later at the Moscow conference in 1943 , the major Allied Powers— China , the USSR , the U.K. , and the U.S. —issued a joint declaration recognizing the necessity "of establishing at the earliest practicable date
16884-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line. By early November, Bulgaria, the Ottoman Empire and Austria-Hungary had each signed armistices with the Allies, leaving Germany isolated. Facing a revolution at home , Kaiser Wilhelm II abdicated on 9 November, and
17018-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when
17152-403: Was challenged by Britain's withdrawal into so-called splendid isolation , the decline of the Ottoman Empire , New Imperialism , and the rise of Prussia under Otto von Bismarck . Victory in the 1870–1871 Franco-Prussian War allowed Bismarck to consolidate a German Empire . Post-1871, the primary aim of French policy was to avenge this defeat, but by the early 1890s, this had switched to
17286-557: Was pursued as an indirect way of bringing what is really a contentious case before the court. Examples of advisory opinions can be found in the section advisory opinions in the List of International Court of Justice cases article. One such well-known advisory opinion is the Nuclear Weapons Case . Article 94 establishes the duty of all UN members to comply with decisions of the court involving them. If parties do not comply,
17420-510: Was reflected by the fact that several hundred international treaties and agreements conferred jurisdiction upon it over specified categories of disputes. In addition to helping resolve several serious international disputes, the PCIJ helped clarify several ambiguities in international law that contributed to its development. The United States played a major role in setting up the PCIJ but never joined. Presidents Wilson, Harding, Coolidge, Hoover, and Roosevelt all supported membership, but did not get
17554-654: Was refused. Early on the morning of 4 August, the Germans invaded, and Albert I of Belgium called for assistance under the Treaty of London . Britain sent Germany an ultimatum demanding they withdraw from Belgium; when this expired at midnight, without a response, the two empires were at war. Germany promised to support Austria-Hungary's invasion of Serbia, but interpretations of what this meant differed. Previously tested deployment plans had been replaced early in 1914, but those had never been tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Beginning on 12 August,
17688-667: Was returning to Germany when it sank two British armoured cruisers at the Battle of Coronel in November 1914, before being virtually destroyed at the Battle of the Falkland Islands in December. The SMS Dresden escaped with a few auxiliaries, but after the Battle of Más a Tierra , these too were either destroyed or interned. Soon after the outbreak of hostilities, Britain began a naval blockade of Germany . This proved effective in cutting off vital supplies, though it violated accepted international law. Britain also mined international waters which closed off entire sections of
17822-645: Was subsequently convened in Washington, D.C., in April 1945, involving 44 jurists from around the world to draft a statute for the proposed court. The draft statute was substantially similar to that of the PCIJ, and it was questioned whether a new court should even be created. During the San Francisco Conference , which took place from 25 April to 26 June 1945 and involved 50 countries, it was decided that an entirely new court should be established as
17956-781: Was the foundation of German foreign policy but in 1890, he was forced to retire by Wilhelm II . The latter was persuaded not to renew the Reinsurance Treaty by his new Chancellor , Leo von Caprivi . This gave France an opening to agree the Franco-Russian Alliance in 1894, which was then followed by the 1904 Entente Cordiale with Britain. The Triple Entente was completed by the 1907 Anglo-Russian Convention . While not formal alliances, by settling long-standing colonial disputes in Asia and Africa, British support for France or Russia in any future conflict became
