**Chap 1 : The Nature and Development of International Law** International law is a distinct legal framework that governs relations among states, international organizations, and sometimes individuals. Unlike municipal law (domestic law), which operates within a state\'s boundaries and has established legislative, judicial, and executive branches, international law lacks a centralized authority to legislate, adjudicate, or enforce rules universally. Despite these structural differences, international law functions to create order and regulate interactions at a global level. **Key Features of Law in Society** [The Foundation of Law in Communities:] - Law organizes society by defining permissible and impermissible behaviors. - It is both permissive (allowing contractual relationships) and coercive (penalizing violations). - Legal systems reflect the values and preoccupations of their respective societies. [Public vs. Private International Law:] - Private International Law: Addresses conflicts where foreign elements are involved within a domestic legal framework, e.g., determining applicable laws in international contracts. - Public International Law: Regulates interactions between states and international entities, encompassing issues like diplomacy, trade, human rights, and conflict resolution. [Customary Practices vs. Legal Obligations:] - Some practices, like saluting foreign warships, are customs driven by courtesy (international comity) and not legally binding. - International law, however, is distinct in its legal obligations, even though it shares intersections with ethics and morality. **Challenges in Defining International Law** [Absence of Traditional Legal Structures:] - No centralized legislature: While the UN General Assembly exists, its resolutions are generally non-binding. - Limited judiciary: The International Court of Justice (ICJ) adjudicates disputes only when parties consent, and compliance is not guaranteed. - Lack of an executive authority: The UN Security Council can enforce resolutions but is often constrained by the veto power of its five permanent members. [Austin's Theory of Sovereignty:] - John Austin\'s concept of law as commands issued by a sovereign and backed by sanctions excludes international law, relegating it to \"positive morality.\" - Critics argue this perspective oversimplifies law by focusing excessively on coercion and failing to capture the nuances of legal systems. [Coercion and Compliance] Enforcement in international law is decentralized, relying on mechanisms like treaties, customary practices, and collective actions (e.g., sanctions or interventions). **Development and Scope of International Law** [Universal vs. Regional Rules]: - Universal laws apply broadly to the international community (e.g., treaties like the UN Charter). - Regional laws govern specific groups of states based on shared geography or ideology (e.g., Latin American practices of diplomatic asylum). [Dynamic and Evolving Nature:] - International law adapts to emerging challenges such as cyber security, space exploration, and global health crises. - Historical developments, including decolonization and globalization, have expanded its reach and relevance. **Law and Politics in the International System** The interplay between law and politics in the global arena is complex. International disputes often involve legal justifications from all sides, yet there is no ultimate arbiter. The lack of centralized institutions complicates enforcement but does not diminish the importance of international law in fostering order and cooperation among states. International law remains a vital framework, emphasizing norms, agreements, and collaborative governance over coercion, thereby reflecting the collective aspirations for a stable and just world order. **The Role of Force in International Law** In the international legal system, the use of force occupies a complex position. Unlike domestic legal systems, international law lacks a unified or centralized mechanism for imposing sanctions or enforcing compliance. Nevertheless, force is legally permissible in certain circumstances, which are carefully regulated by international rules and norms. [The Use of Force and Sanctions in International Law] - United Nations Framework: - The United Nations Security Council (UNSC) plays a pivotal role in authorizing the use of force under *Chapter VII* of the UN Charter when there is a determination of a *threat to peace*, *breach of peace*, or *act of aggression*. - Sanctions can be - Economic (e.g., 1966 sanctions against Rhodesia). - Military (e.g., intervention during the Korean War in 1950) - Both (e.g., measures against Iraq in 1990 after its invasion of Kuwait). - However, enforcement under the UNSC often requires the cooperation of the five permanent members (P5), and their veto power frequently obstructs collective action. [Historical Examples:] Korean War (1950) A rare instance of collective military action under the UN framework, enabled by the USSR\'s temporary absence from the Security Council. Iraq (1990) Coordinated sanctions and military action following Iraq's invasion of Kuwait. [Self-Help and the Role of Force by States] - Self-Defense: - States may use force *in self-defense* under *Article* *51* of the UN Charter if they are victims of an armed attack. - Such actions must be proportionate and necessary, and they often require justification at the international level. - Reprisals and Retaliatory Measures: - States may also take unilateral action in response to illegal acts by other states. However, the legality of such measures is subject to scrutiny under international law. - Lack of Central Authority: - Unlike domestic systems where the government monopolizes the use of force, international law allows states to determine their own course of action in response to aggression or violations, given the absence of an overarching enforcement body. [Theoretical Perspectives on Force in International Law] - Force as a Defining Element - Some theorists emphasize force as a central aspect of international law, arguing that the ability to impose sanctions or engage in self-defense is what gives international law its legal character. - However, critics argue this view is flawed because the sanctions are wielded by states themselves rather than by a centralized system, challenging the coherence of international law as a legal system. - Trend Toward Restricting Force: - Modern international law increasingly seeks to *restrict the use of force*, as seen in the emphasis on peaceful resolution of disputes and the prohibition of aggression under the UN Charter. - Ironically, this restriction has led some critics to claim that the less force is permitted, the less \"legal\" international law appears, since coercion is often associated with enforceability. [The Obligation to Obey International Law] The crux of the debate about force and international law lies in whether states feel genuinely bound by international legal rules. If states do not regard these rules as obligatory, then the legitimacy of international law itself comes into question. Factors influencing compliance include: - Reciprocity and Mutual Interests States often follow international law because it facilitates predictable and stable relationships. - Reputation and Diplomacy Adherence to international norms bolsters a state's standing in the global community. - Consequences of Non-Compliance While enforcement mechanisms may be limited, defying international law can result in economic sanctions, diplomatic isolation, or military reprisals. [The Role of Force in International Law] - Absence of Unified Sanctions: - Unlike municipal (domestic) law, international law lacks a unified system of sanctions. - Legal use of force is justified in specific contexts, such as: - Sanctions by the UN Security Council (economic or military, e.g., Korea in 1950, Iraq in 1990). - Self-defense by states in response to aggression or illegal acts. - Challenges in Coercive Action - Joint action under the UN framework is rare, as it requires consensus among the Security Council\'s permanent members. - Instances like the Korean War were exceptional due to specific geopolitical conditions (e.g., the USSR\'s absence during key votes). - Self-help Mechanisms - States may unilaterally resort to self-defense or reprisals, acting as their own judges in the absence of centralized enforcement bodies. - This highlights the horizontal structure of international law, where enforcement is decentralized and dependent on state action - Restricting Force - International law increasingly emphasizes limiting the use of force. - This trend paradoxically raises questions about the effectiveness of international law in managing conflicts, as its ability to compel compliance diminishes. [The International System and Compliance] - Horizontal Legal Order - Unlike domestic law, international law operates within a system of legally equal sovereign states. - States create and adhere to laws by mutual consent rather than through hierarchical imposition. - Sources of International Law - Treaties: Binding agreements between states. - Customary Law: Practices recognized as legally obligatory - Observance Despite Violations - States generally observe international law; violations are the exception and often highlight systemic weaknesses rather than invalidating the system - The widespread compliance stems from a need for stability, predictability, and a shared legal framework to resolve disputes. - Reciprocity and Self-Interest - States comply due to reciprocal arrangements (e.g., diplomatic immunity) that ensure mutual benefits. - Violating international norms can have long-term consequences, discouraging non-compliance. [The Binding Nature of International Law] - Consent vs. Consensus: - Traditional theory holds that states are bound by rules they consent to. However, this fails to explain: - The binding nature of pre-existing rules on newly independent states. - Why withdrawal of consent does not nullify a state\'s obligations. - Consensus as a Foundation - Modern approaches emphasize *consensus* over explicit consent: - Rules evolve from the collective acceptance of norms by the international community. - States recognize the system's overall framework, even while contesting specific rules. - Community Acceptance: - International law relies on an implicit acceptance of its principles and structures as a necessary framework for global interaction. - The principle of *pacta sunt servanda* (agreements must be kept) underpins treaty law and reinforces the system's authority. **The Function of Politics in International Law** - Interconnection of Law and Politics - Law and politics are inherently linked; a complete separation is not possible. - In domestic systems, legal processes are structured to limit political influence (e.g., separation of powers in the UK and US). - Domestic Legal Systems vs. International Law - Domestic systems have clear divisions between lawmaking (legislature) and enforcement (judiciary). - International law lacks such separation; states act as lawmakers, interpreters, and enforcers. - Role of Politics in International Law - Politics plays a central role, with power dynamics influencing international legal processes. - International law seeks harmony but must contend with state competition and strategic interests. - Limitations of International Law - No overarching authority or enforcement mechanism exists internationally. - Moral principles only influence law when legally formalized (e.g., South-West Africa case). - It cannot provide instant solutions to all conflicts due to structural weaknesses. - Contrasting Approaches to International Law - Utopianism: Overestimates law\'s ability to solve global problems, failing in complex realities. - Cynicism: Focuses solely on power politics, dismissing law\'s potential for cooperation. - Pragmatic Middle Ground - Recognizes both the strengths and weaknesses of international law. - International law offers a framework for communication, dispute moderation, and collective values like order, welfare, and justice. - Importance of Legal Frameworks - While imperfect, international law provides stability and predictability in the anarchic global system. - It channels political interactions through agreed norms, supporting peaceful coexistence and cooperation. **Historical Development of International Law** [Origins in Western Culture and Sovereignty] Modern international law is rooted in Western political and cultural evolution. The rise of sovereignty and nation-states created the need for a framework to regulate inter-state relations. [Ancient Beginnings] 2100 BC: Treaty between Lagash and Umma defined boundaries under divine authority. 1258 BC: Treaty of Kadesh between Egypt (Rameses II) and the Hittites established peace, territorial respect, and alliances. Treaties often formalized subservience or alliances against powerful empires. [Classical Greece] Contributions to European thought included philosophy, analysis, and debate. Greek city-states engaged in diplomacy, trade treaties, and rules for envoys, but lacked a universal moral framework. Greek ideology focused on city-state competition, excluding others as barbarians. [Roman Contributions] Jus Civile Early Roman law applied strictly to citizens; formalistic and limited. Jus Gentium Developed for relations with foreigners; became the universal law of the empire. Overseen by the Praetor Peregrinus Greek Natural Law influenced Roman legal theory Rules of universal relevance, rooted in human reason, transcending nations. Inspired later international law and human rights doctrines. Compilation of Roman law in the Corpus Juris Civilis(AD 534) laid foundations for later European legal systems. [Medieval Europe and Roman Legacy] After the fall of Rome, the Corpus Juris Civilis became a resource for Europe\'s legal revival during the Middle Ages. The universality and rationality of Roman law influenced the emerging legal order. [Islamic Contributions] Focused on the concept of unity (Dar al-Islam) and hostility towards non-Muslim states. Developed rules of humane warfare and diplomatic norms Hospitality and safety for diplomats (aman) Respect for promises in international agreements Non-Muslims (People of the Book, e.g., Jews and Christians) were given protection but held subordinate status. Philosophical and Legal Foundations Universal application of law and rational deduction (Natural Law) are cornerstones of international law. Rationality and human reason were considered superior to force in legal principles, providing enduring influence on Western legal thought. **The Middle Ages and the Renaissance in International Law Development** [The Middle Ages] Church Authority Dominated by the unified authority of the Church and canon law, applied universally across Europe. Conflicts between the Papacy and Holy Roman Empire, with eventual Church dominance. Trade and Maritime Law Emergence of Law Merchant to regulate trade and foreign merchants. Maritime customs influenced by the Rhodian Sea Law and the Rolls of Oleron contributed to early cross-border legal frameworks. Early trade and maritime codes, though national, laid the foundation for international law. [The Renaissance] Cultural Transformation Greek scholars fleeing to Italy after the fall of Constantinople (1453) invigorated European thought. Printing and economic growth led to individualistic, scientific, and humanistic ideas. Rise of Nation-States Consolidation of sovereign states (e.g., England, France, Spain) required regulation of inter-state relations. Machiavelli's The Prince highlighted the pursuit of power, diplomacy, and the balance of power. Decline of Religious Unity Reformation and religious wars shifted focus from Church dominance to state sovereignty. [Foundations of Modern International Law] Sovereignty and State Supremacy Jean Bodin's Six Livres de la République (1576) formalized the concept of state sovereignty, emphasizing lawmaking authority within states and their supreme power externally. Natural Law Revival Rediscovery of Greco-Roman ideas, especially Natural Law, emphasized rational and universal legal principles. International law became an extension of Natural Law principles, applying to all humanity. [Pioneering Thinkers in International Law] Francisco de Vitoria Advocated for the inclusion of non-European nations within international law based on Natural Law. Defended rights of South American Indigenous peoples while supporting missionary activities and Spanish dominance. Francisco Suárez Rooted international law's obligatory character in Natural Law principles. Alberico Gentili Secularized international law, minimizing theological influences. De Jure Belli focusing on the laws of war and treaties. [Hugo Grotius: Father of International Law] De Jure Belli ac Pacis (1623-1624): Advocated for a rational, secular foundation for international law. Distinguished between just and unjust wars, influencing concepts of self-defense and aggression. Proclaimed the freedom of the seas, opposing territorial claims on high seas. Significance Grotius's work integrated philosophical ideas with the realities of his time, shaping modern international legal frameworks. [Impact of Socio-Cultural Context] Renaissance ideas and the rise of sovereign states fostered the intellectual environment for international law. Legal theories, reflecting prevailing societal and political dynamics, developed alongside expanding commerce and state interaction. **Positivism and Naturalism: Divergent Philosophies in International Law** [1. Emergence of the Two Schools] - Naturalism Grounded in *Natural Law*, this approach viewed international law as inherently moral, universal, and rooted in rational or divine principles. - Samuel Pufendorf Identified international law entirely with the law of nature. Dismissed state practices like customs and treaties as irrelevant to legal foundations. Criticized for detaching international law from political realities. - Positivism Based on empirical observation, focusing on state practices, customs, and treaties as the source of international law. - Richard Zouche Rejected Natural Law and emphasized practical examples of state behavior. - Cornelius van Bynkershoek Concentrated on modern state practices, particularly regarding neutrality in war and the freedom of the seas. Advocated for a pragmatic approach rooted in state behavior. [2. Philosophical Foundations] - Naturalism Derived from the belief in universal principles based on human reason or divine order. Often moralistic, focusing on what ought to be rather than what is. - Positivism Inspired by the scientific empiricism of Locke and Hume, emphasizing observation and experience over abstract reasoning. Denied innate principles, focusing on what states actually did rather than theoretical ideals. [3. Positivism and the Nation-State System] Gained prominence after the *Peace of Westphalia* (1648), marking the rise of the modern state system and the concept of sovereignty. Sovereignty, as articulated by thinkers like Bodin and Hobbes, aligned well with positivism, emphasizing the supreme authority of states and the practical regulation of inter-state behavior. [4. Intersection of Naturalism and Positivism: Vattel's Contribution] Emerich de Vattel Blended Natural Law principles with a pragmatic approach. Introduced the idea of *state equality* in international law, asserting that small republics were as sovereign as large kingdoms. Distinguished between laws of conscience (Natural Law) and laws of action (practical law), emphasizing the latter for international relations. [5. Transformation of Natural Law into Natural Rights] While Natural Law was sidelined by positivism, it resurfaced as the foundation for *natural rights*, emphasizing individual freedoms and political equality. - Key Theories - Social Contract theories by Hobbes (absolute sovereignty) and Locke (conditional acceptance of authority) highlighted individual rights and state legitimacy. - Impact Inspired revolutionary ideals in the American and French Revolutions. Became central to modern democratic societies and human rights discourse. [6. Dual Role of Natural Law] Progressive Role Supported revolutionary concepts like equality, liberty, and human rights. Conservative Role Justified sovereignty and the sanctity of existing social orders, depending on its interpretation (divine vs. secular). **The Nineteenth Century: A Practical, Expansionist, and Positivist Era in International Law** [International Law After the Napoleonic Wars] - The Congress of Vienna (1815), which ended the Napoleonic Wars, solidified a new European international order based on the *balance of power*. - This period marked the transition from intellectual debates to practical, expansionist approaches in international law, emphasizing state interests and sovereignty. - Eurocentrism - International law became primarily Eurocentric, representing the interests of European, Christian states. - Non-European countries could only interact with Europe on terms set by Western powers, leading to a paradox: While international law expanded geographically with European empires, its conception became less universal and more reflective of European values. [The Influence of Democracy, Nationalism, and Revolution ] - Democracy and Nationalism - Fueled by the *French Revolution* and subsequent wars, democracy and nationalism spread across Europe. *Foreign policy*, once controlled by aristocratic elites, now became a matter of national interest, impacting both the positive and negative aspects of international relations. *Self-determination* emerged as a challenge to the multinational empires, while nationalism spurred the *unifications of Germany and Italy* and promoted expansionist and sometimes racial superiority ideas. - Democracy\'s Impact - Democracy not only gave individuals more political influence but also introduced new responsibilities. Wars became a concern for the entire population, leading to the introduction of conscription and the formation of large national armies. [Industrial Revolution and Global Expansion] The *Industrial Revolution* transformed Europe, creating economic divisions between *capital and labor* and facilitating Western expansion globally. Technological and Economic Factors The growth of trade and communication networks necessitated greater international cooperation. International law adapted to accommodate new challenges posed by the rapid expansion of European influence worldwide. [Rise of International Institutions] - International Cooperation - New international agreements were needed to regulate trade, navigation, and communication. Notable agreements include: - 1815 : The Final Act of the Congress of Vienna, which established the principle of freedom of navigation for international waterways. - 1856 : A commission for the Danube River was created. - 1865: The International Telegraphic Union was formed. - 1874: The Universal Postal Union was established. - Humanitarian Efforts and Warfare Regulation - The International Committee of the Red Cross(1863) helped establish the Geneva Conventions (1864), focusing on the humanization of warfare. - The Hague Conferences(1899 and 1907) led to the creation of the Permanent Court of Arbitration and formal rules on prisoner treatment and warfare conduct. [Expansion of International Law through Conferences and Textbooks] Throughout the century, international conferences proliferated, leading to an expansion of rules governing warfare and the treatment of prisoners, as well as establishing various international institutions. Academic Growth The study of international law became institutionalized with the appointment of professors and the publication of textbooks focused on state practice and the role of treaties and customs in the development of international legal norms. [The Paradox of State Sovereignty and the Common Will] - Positivist Theories and State Will - While positivist theories emphasized state sovereignty, they also introduced the idea of a \"common will\" that bound states. This raised a paradox: Could the collective will of states limit the sovereignty of individual states? - This paradox, highlighted by legal theorist Triepel, revealed a tension between state sovereignty and international rules. - Triepel's work raised questions about the supremacy of state will, suggesting that the collective will of states could create legal rules over which no single state had complete control. [The Development of International Law in the Nineteenth Century ] State Practice and Legal Development The century saw numerous publications on international law emphasizing the importance of state practice and the role of state behavior in shaping legal norms. **The Twentieth Century: A Period of Change, Conflict, and Institutional Development in International Law** [1. The Legacy of World War I] - Decline of European Power - The First World War (1914-1918) marked the end of an era of European dominance in global affairs. - European empires, which had once ruled much of the world, were weakened, and the ideologies that had supported their supremacy began to falter. - The war led to a decline in European self-confidence and undermined the assumptions of progress that had been central to the previous century. A period of self-questioning took hold, reflected in both law and culture. [2. The League of Nations] - Creation and Challenges: - The *1919 Peace Treaty* resulted in the formation of the *League of Nations*, marking a new attempt to prevent future wars and maintain international peace. - The League had an *Assembly* and an *Executive Council*, but was deeply flawed from the beginning due to the absence of the United States and the *Soviet Union* for much of its existence. - While it had some successes in maintaining order, the League failed in the face of aggressive actions by states: - Japan invaded China in 1931 and left the League shortly after. - Italy attacked Ethiopia, and Germany expanded aggressively in Europe without facing serious opposition from the League. - The \*\*Soviet Union\*\* was expelled in 1939 after invading Finland. - Despite these failures, the League helped lay the groundwork for the establishment of the *United Nations* (UN) after World War II. [3. International Legal Developments Between the Wars ] - New Institutions - The *Permanent Court of International Justice* (1921), later succeeded by the *International Court of Justice* (1946), became a key institution for the peaceful resolution of disputes. - The *International Labour Organisation* (ILO) was established after the war and remains active today. - Mandates System - Following the defeat of the Central Powers, the mandates system was created, in which former colonies of defeated powers were administered by Allied countries on behalf of their populations, rather than being annexed outright. - This system was a precursor to international efforts in human rights and *minority protections*, though it was not entirely successful. - These early efforts to protect human rights paved the way for later global human rights protections. [4. The United Nations and Post-WWII Reforms ] - Shift in Global Power - After the Second World War, the League of Nations was replaced by the United Nations in 1946, with the goal of addressing the League\'s shortcomings and reflecting the new global power dynamics. - The establishment of the UN in New York symbolized the shift away from European dominance, as power moved to the United States and the Soviet Union. - Decolonization and Globalization - The post-war era saw the rise of decolonization, with former colonies gaining independence and joining the UN. - The UN General Assembly now includes 192 member states, making it a truly universal institution, reflecting the diverse global order emerging in the wake of colonialism. [5. Trends Continuing from the Nineteenth Century] - Growth of International Agreements The twentieth century saw an increase in the number of *international treaties*, conventions, and agreements, covering a wide range of issues from trade to human rights. - Strengthening of Arbitration The system of international arbitration continued to grow, providing a peaceful means for states to resolve disputes. - Expansion of International Organizations The development of international institutions like the UN and the World Trade Organization (WTO) further solidified the role of international law in managing state interactions and promoting cooperation. [6. The Rise of International Law as a Discipline] - Legal Theories and Human Rights - The period between the wars saw the development of more structured legal theories, particularly concerning *human rights and international justice* - The *UN Declaration of Human Rights* (1948) and other conventions laid the foundation for modern international human rights law, furthering the shift from state-centric to individual rights in global legal frameworks. **Communist Approaches to International Law** [1. Marxist Theory and Law:] Law as a Tool of Class Domination Classic Marxist theory viewed law and politics as instruments through which the ruling classes maintained their dominance. It argued that the essence of economic life was the control of the means of production, which determined all power in society. - In Marxist theory, the opposing forces of *capital and labour* would inevitably lead to a revolution, resulting in the creation of a non-exploitative, socialist society. - National states, being dominated by the capitalist class, were expected to disappear as socialism emerged. Law, as part of the capitalist structure, was expected to wither away once a new societal basis was established. This also implied that international law, as founded upon the state system, would cease to exist. 2\. Transitional Phase Post-Revolution - Acknowledging International Law in a Transitional Period - The reality of the Soviet Union (USSR) surrounded by capitalist nations led to a modification of this theoretical position. A *transitional phase* was deemed necessary, where the international system could not immediately shift to socialism - During this phase, international law was still recognized as a valid system, but it was criticized as a tool for capitalist exploitation. The need for some forms of economic and technical cooperation was acknowledged as essential for maintaining the international social order. - Soviet theorists like *Korovin and Pashukanis* dominated during this time, with Pashukanis viewing international law as a space where antagonistic class systems would find temporary accommodation. [3. Soviet Legal Thought Under Stalinism ] - Shift to Class Warfare in International Law: - With the rise of *Stalinism* and the policy of \"socialism in one country,\" the Soviet Union\'s approach to international law hardened. Pashukanis, in particular, recanted his earlier position and argued that international law was not a temporary compromise but a means to conduct the *class war* - The Soviet Union would only abide by the rules of international law that aligned with its goals, and it would not be bound by rules it had not explicitly consented to. - This period was politically reflected in the USSR's attempt to *join the League of Nations* and its efforts to engage with Western powers. [4. International Law During the Cold War] - Vyshinsky's Legalistic Approach - Soviet legal theorist *Vyshinsky* emphasized a more legalistic approach to international law during the late 1930s, focusing on principles such as *national self-determination*, *state sovereignty, and equality of states.* - However, the USSR did not consider international law to represent a singular legal system binding all states. It maintained that the Soviet Union would act based on *Leninist-Stalinist foreign policy* ideals and was not bound by rules not aligned with its goals. - Transition to Peaceful Co-existence Post-Stalin - After Stalin's death and under *Khrushchev*, Soviet foreign policy shifted toward *peaceful coexistence*, reflecting a theoretical move away from the belief in inevitable war between capitalist and socialist countries. - This marked the beginning of mutual tolerance and cooperation between states with differing social systems, reducing the ideological divide that had previously dominated Soviet legal thought. [5. Tunkin's Concept of General International Law ] - International Law with Universal Scope - Soviet theorist *Tunkin* articulated a vision of international law that transcended the ideological divide between capitalist and socialist states. He argued that international law was a single system with *universal scope*, founded on agreements between states that reflected their mutual wills. - Tunkin defined contemporary international law as the *aggregate of norms* created by state agreements, regulating relations in the pursuit of *peaceful coexistence* and the *freedom and independence of peoples*, and enforceable by coercion when necessary. - This perspective reflected a commitment to state sovereignty, the recognition of different social systems, and the role of sanctions within the law. [6. Soviet Views on International Law and State Sovereignty ] - Coercion and State Sovereignty - According to the Soviet definition of international law, it was an instrument for regulating relations between states in the context of *conflict* and c*ooperation*, ultimately aimed at ensuring *peaceful coexistence*. - The concept of *coercion* was central to the Soviet understanding of international law, reflecting the *positivist* influences on Soviet legal thought. - The *will of the ruling classe*s of states was expressed through international law, and the enforcement of international law often involved coercive measures taken by states, either individually or collectively. [7. Sources of International Law ] - Treaties and Customary Law - Initially, the Soviet approach recognized *treaties* as the sole valid sources of international law. Over time, however, *customary international law* was also accepted, albeit with a significant focus on the *opinio juris* (the belief that a practice is legally obligatory). - Soviet legal theorists argued that state practice did not necessarily have to be universal to create a custom, but recognition of the legal form of custom was essential. **Peaceful Co-existence and the Evolution of Soviet International Law** [1. Core Principles of Peaceful Co-existence:] - Non-Intervention and State Sovereignty The doctrine of *peaceful co-existence* in Soviet legal theory was founded on the principles of *non-intervention* in the internal affairs of states and the *sovereignty* of nations. It was explicitly opposed to the idea of a *world authority*, considering it a violation of these core principles - Basic Concepts - Peaceful co-existence included notions of *good neighborlines, international cooperation*, and the *observance of international obligations in good faith*. While these principles aligned with widely accepted norms of international law, Soviet theorists saw them as reflecting an ideological stance, specifically the class struggle between socialism and capitalism.The theory posited that this struggle was not to be waged through armed conflict but through diplomatic and legal means. [2. Socialist International Law] - Soviet Shift Toward Socialist Law Initially, Soviet theorist *Tunkin* rejected the development of regional systems of international law. However, in time, he accepted the idea of a *socialist international law*, emphasizing the special relationship between socialist (communist) states. - The USSR viewed relations between communist states as a *new, higher form of international relations*. This relationship was based on common socio-economic factors, which provided an objective foundation for *lasting friendship* and cooperation. In contrast, international capitalism was seen as inherently exploitative, with stronger states oppressing weaker ones. - Principles of Socialist Internationalism Socialist international law was rooted in the *principles of proletarian internationalism*, which included not only respect for sovereignty and non-interference but also a duty to assist each other in defending those rights against capitalist threats. These principles emerged through *custom and treaty*, solidifying a unique legal framework between socialist states. [3. Appeal of Soviet Principles to the Third World] Territorial Integrity and Sovereignty: Soviet emphasis on *territorial integrity* and *sovereignty* resonated with many *developing nations* in the *Third World*, which sought to establish their *national identities* and counter the influence of Western powers. These principles provided a legal and political foundation for the *decolonization* movements and the independence of newly established states in Asia, Africa, and Latin America. [4. Re-evaluation During Perestroika] - Shift Away from Ideological Conflict - With the onset of *perestroika* (restructuring) in the late 1980s, the Soviet Union began to reconsider its international legal stance. The Cold War era's focus on the *capitalist-socialist conflict* was gradually replaced by an emphasis on *global interdependence* and the *necessity for international cooperation* - The doctrine *of peaceful co-existence* was modified, with the concept of *class warfare* largely abandoned. Instead, the emphasis shifted to *universal human values* and the need to address *global problems* through collective efforts, underlining the growing importance of international law in the world community. - Soviet leaders began to acknowledge that interventions, such as the *1968 invasion of Czechoslovakia* and the *1979 intervention in Afghanistan*, were *contrary to international law*, and the strengthening of the *international legal system* was seen as crucial to the *rule of law* in international relations. [5. The Collapse of the Soviet Union and Its Impact on International Law] - Post-Soviet Transition - The dissolution of the Soviet Union in 1991 marked the end of the *Cold War* and the emergence of a new international system characterized by a *multipolar* world order. *Russia*, as the successor to the USSR, began to integrate into the *Western political system* and define its actions based on its *national interests* rather than ideological hostility - The collapse of the Soviet bloc led to significant geopolitical shifts, including the *independence* of the *Baltic states* and the *breakup of Yugoslavia*, which brought instability to Europe. These events highlighted the *limitations of the United Nations* and the challenges of navigating a post-Cold War world. [6. The Chinese Perspective on International Law] Divergence from Soviet Views The Soviet approach to international law, particularly the concept of peaceful co-existence, was met with *suspicion* and *disdain* by China. By the late 1950s, China had distanced itself from Soviet views, particularly as the two communist powers became increasingly estranged. *Chinese theorists* regarded Western international law primarily as a tool to preserve the dominance of the *bourgeois* class and were critical of the Soviet focus on maintaining the *status quo* through *superpower supremacy* **Chinese Conception of Law and International Law** [1. Historical and Cultural Background] - Confucian Influence: The Chinese conception of law has been shaped by its *Confucian* traditions, which did not place law in the central role seen in Western societies. Confucianism emphasized *moralit*y, *social harmony*, and the importance of *example* over strict legal rules and sanctions. The *bureaucracy* aimed to ensure stability and order by fostering moral conduct and societal balance, rather than relying on legal systems designed to protect individual rights in the Western sense - Shift to Marxism-Leninism After the success of the *Chinese Communist Revolution*, this Confucian philosophy was replaced by *Marxism-Leninism*, which emphasized *class struggle* and the idea that law would be a tool for advancing socialist principles. The new legal approach focused on societal transformation and the *elimination of capitalist class structures*. [2. Chinese Views on International Law:] - Recognition of Multiple Legal Systems China recognized and engaged with various systems of international law, including the Western, socialist, and revisionist (Soviet) systems. Chinese thinkers seemed to suggest that a universal system of international law would only be possible with the eventual global spread of socialism, reflecting their Marxist views. - Treaties as the Primary Source of International Law In practice, *international agreements* were recognized as the primary source of international law. China entered into many international treaties and conventions and generally adhered to them, in line with its evolving international status. However, there were exceptions, such as China\'s *disavowal* of the so-called \"*unequal treaties*\" imposed by foreign powers (particularly \*\*Tsarist Russia\*\*) in the 19th century, which resulted in the annexation of Chinese territory. [3. The Role of Power and Expediency] International Law and Politics For much of its modern history, China treated international law as part of *international politics*, subject to the realities of *power*, *expediency*, and *ideological considerations*. International legal norms were respected when they aligned with China\'s *national interests*, but they were disregarded when they conflicted with those interests. This pragmatic approach was influenced by China\'s historical experience of foreign domination and the desire to safeguard its sovereignty. [4. China\'s Shift Toward Active Engagement] - Post-Isolationism Following the end of its *isolationist period* and its entry into the *United Nations*, China began to adopt a more *active* and *engaged* role in international relations. This shift was driven by China\'s rapid *economic growth* and the increasing importance of *global political influence*. - Legalisation of China\'s Approach to International Law As China grew in economic and political stature, its approach to international law began to evolve. While earlier Chinese foreign policy was more driven by pragmatic considerations, the *legalisation* of international law became more evident, similar to the Soviet experience. China began to engage more consistently with international legal norms, though its approach remained shaped by its broader political and ideological priorities. **The Third World and the Evolution of International Law** [1. The Disintegration of Colonial Empires] Birth of New States The collapse of colonial empires after World War II led to the creation of numerous *new states*\*\* in the so-called *Third World*. These newly independent countries were marked by a legacy of colonial subjugation, along with significant challenges in social, economic, and political development. As a result, these states began to challenge the structures and doctrines of international law that had been shaped largely by European colonial powers. [2. Rejection of Eurocentric International Law]Eurocentric Origins - International law, particularly in the 19th century, was heavily based on *Eurocentrism*, reflecting the values and interests of *Christian, urbanized, and expanding Europe*. This system of international law did not cater to the needs or aspirations of the newly independent states in the mid-20th century. These nations felt that the existing international legal framework had been a tool for their subjugation. - Rejection of Colonial Power Structures - The newly independent nations rejected international legal principles that had historically upheld the power and domination of the West. However, they did not discard the core principles of international law entirely. On the contrary, the new nations embraced principles such as *sovereignty, equality of states*, *non-aggression, and non-intervention* as a means to secure their independence and develop within a common legal framework. [3. Universalisation of International Law] - Universal Scope of International Law As a result of the decolonization process, *international law* began to lose its European-based homogeneity and assumed a more *universal* character. The composition of international bodies like the *International Court of Justice* and the *Security Council* of the *United Nations* reflected this shift. For example, the inclusion of *Afro-Asian and Latin American* states in the UN Security Council and International Court of Justice demonstrated the increasing influence of the Third World on international law. - Increased Influence in the General Assembly The *General Assembly* of the UN, where Third World countries form the majority of the 192 member states, became the focal point for promoting their interests. *Resolutions* and *declarations* emerging from the Assembly have reflected the concerns of these nations, particularly regarding *sovereignty, self-determination, and economic justice.* [4. Key Developments in International Law] - Self-Determination One of the major milestones for the Third World in international law was the *Declaration on the Granting of Independence to Colonial Countries and Peoples*(1960). This declaration recognized the *right of colonies to gain sovereignty* and emphasized the *principle of self-determination*. While the principle of self-determination is now widely accepted as a fundamental rule of international law, its full application remains uncertain in some areas. - Economic Self-Determination Third World countries also advocated for *economic self-determination*, asserting the *right to permanent sovereignty over natural resources*. This led to significant developments in international economic law, such as the establishment of organizations like the *General Agreement on Tariffs and Trade (GATT), the United Nations Conference on Trade and Development (UNCTAD), and the International Monetary Fund (IMF) and World Bank*. These institutions became essential in advancing the economic interests of newly independent countries. [5. Conflicts with Industrialized Nations:] Economic Disputes The interests of the new Third World states often conflicted with those of *industrialized nations*. Disputes over issues like *nationalization* of resources, particularly in oil-producing countries, were common. However, despite these tensions, international law was not discarded. Rather, the new states sought to use international law to secure their interests, while opposing legal principles they felt undermined their sovereignty and development. [6. Diversity within the Third World] Lack of Homogeneity Although the Third World countries shared a history of colonial domination, they were far from homogenous. These states differed widely in *culture*, *social* *and economic development, and political systems*. Factors such as natural resources, geographical location (landlocked vs. coastal states), and economic structure contributed to significant differences in their positions on international legal issues. This diversity was reflected in the varying stances these states took on issues such as economic policies, the environment, and human rights. [7. Future Evolution of International Law] - Potential for Tangible Differences in Approach As the fervor of decolonization subsides, new differences in the *legal approach* of Third World countries may emerge. The decline of Western dominance over international law may allow for the incorporation of historical traditions and legal conceptions that predate colonialism, offering alternative approaches to global legal development. - Shift in the Axis of Dispute With the end of the *Cold War*, the focus of global disputes has shifted from *East-West* tensions to *North-South* conflicts, particularly in areas like *economic law, human rights, and the law of the sea*. Modern technology and globalization have also influenced this shift. The growing *interdependence* of nations has led to new challenges and further emphasized the tension between *universalism* (the global spread of Western norms) and *particularism* (cultural and regional differences). [8. Globalization and Cultural Relativism] Universalism vs. Particularism Globalization, which promotes the interdependence of nations and peoples, often carries with it the perception of the *universalization of Western values*. This has sparked concerns that one particular worldview is imposing itself on the global stage. On the other hand, *cultural relativism* has sometimes been used by states to justify actions that violate human rights, arguing that these practices are culturally acceptable within their own context and should be free from international scrutiny. **Chap 3 -- Sources** [1. Introduction] The process of ascertaining the law in domestic legal orders, such as in the English legal system, is relatively straightforward. One typically looks to legislative acts (e.g., Acts of Parliament) or judicial case-law to determine legal rules. This process brings a sense of certainty to the legal system, as there are clear mechanisms to resolve disputes and identify what constitutes law. National legal systems operate with a hierarchical structure, ensuring stability and predictability. In contrast, the situation in *international law* is more complex. Unlike national legal systems, international law lacks a unified legislature, executive, and a central system of courts. Consequently, the process of discovering what constitutes international law is more ambiguous, as there is no single authority to create laws that are universally binding. Instead, international law operates in a decentralized, anarchic world system, where the sovereignty of states often clashes with one another. Despite these challenges, international law does exist and can be ascertained through a variety of *sources*. [2. Defining Sources of International Law] In the context of international law, *sources* refer to the legal provisions and mechanisms that give rise to and establish international legal rules. These sources are distinct from more functional sources such as libraries or academic journals. They specifically refer to those *formal mechanisms* that lead to the creation, recognition, and application of international legal rules. [3. Article 38(1) of the Statute of the International Court of Justice] The most authoritative and widely recognized statement on the sources of international law is *Article 38(1) of the Statute of the International Court of Justice* (ICJ). This provision outlines four primary sources from which international law is derived: - *International Conventions (Treaties)* These are agreements between states that establish rules explicitly recognized by the parties. These conventions can be general (e.g., global treaties) or particular (e.g., bilateral or regional treaties). - *International Custom* This refers to established practices or customs followed by states out of a sense of legal obligation. The practice must be widespread, consistent, and accepted as law by the international community. - *General Principles of Law* These are principles recognized by civilized nations as fundamental to legal systems across the world. Examples include principles of justice, equity, and fairness, which are common to many legal systems. - *Judicial Decisions and Teachings of Highly Qualified Publicists* These are subsidiary sources used to determine the existence and meaning of international legal rules. Judicial decisions, particularly those of the ICJ, can interpret and apply international law, while the writings of leading scholars provide insights into the law\'s development and application. [4. Interpretation and Categorization of Sources:] While the categories outlined in Article 38(1) are generally accepted, some legal scholars have attempted to categorize these sources into *law-creating* and *law-determining* processes: - *Law-creating* processes These include international conventions, customary international law, and general principles of law. These are the primary means by which legal rules are established in international law. - *Law-determining* agencies: These include judicial decisions and the teachings of publicists, which help verify, interpret, and clarify the law. They may not directly create law but play a crucial role in the application and development of international law. In practice, these categories are not always clear-cut. For instance, treaties often reaffirm existing customary law, and judgments of the ICJ can, in some instances, create new rules of law, much like national judges do when interpreting existing laws in municipal systems. [5. Formal vs. Material Sources] Another distinction sometimes made in international law is between formal and material sources - *Formal sources* These sources confer *obligatory character* on the rules. They include *treaties, customary law, and general principles* that are universally recognized as binding. - Material sources These represent the *actual content* of the legal rules---essentially the substance of what international law is about, including specific norms, rules, and practices. However, this distinction has been criticized. The attempt to draw a hard and fast separation between *substantive and procedural* elements of international law is difficult to maintain. International law's peculiar constitutional setup means that the distinction between the form of a rule and its content can often blur. **Custom in International Law** [Introduction ] In primitive societies, rules of behavior emerge almost organically, without formal codification. These customs evolve over time and are maintained through social pressures and practices, eventually becoming formalized through legal systems such as courts and legislatures. However, \*\*custom\*\* remains an authentic reflection of the values and needs of a community at a given time, even as societies modernize. In contemporary legal systems, especially in the developed world, custom often loses its significance, becoming a relic of past traditions. In international law, however, custom remains a dynamic source of law due to the decentralized nature of the international system, which lacks a central governing body. [2. Defining Customary Law] Customary rules in international law can be identified through the *practice and behavior of states*. However, this process is complicated. It is often difficult to distinguish between actions motivated by legal obligations and those stemming from other motivations, such as courtesy or political considerations. This raises several key issues, including how to identify the precise actions of states and the speed at which new rules emerge, as well as how protests or objections impact the development of customary law. [3. The Debate on the Role of Customary Law] Scholars are divided on the value of *customary law* today. Some argue that it is *too slow-moving* to be an effective source of law in the modern world, as it struggles to keep up with the rapid changes in international relations. Others assert that customary law is more important than treaties because it has *universal applicabilitxy* and evolves through the spontaneous actions of states. Some also believe that it reflects the *contemporary concerns* of states, as it emerges from the behaviors and practices that nations adopt in their relations with one another. Despite these differing views, it is acknowledged that identifying the emergence of new customary rules can be difficult amidst a wide variety of state behaviors. While customary law may not always be the best tool for addressing the complex issues that arise in international relations, it can still be effective in certain situations. [4. The Characteristics of Customary Law] - Customary law reflects the decentralized nature of the international system. It is democratic, as all states have a role in its development, though some states may wield more influence than others. One of the key advantages of customary law is its *flexibility*. If the international community is dissatisfied with a particular rule, it can be changed relatively quickly without the need for formal negotiations or world conferences. This flexibility enables customary law to mirror the international consensus and allows for laws to develop without rigid formalities. - A prime example of this process is the creation of the *exclusive economic zone in international law of the sea*, which developed through customary law rather than a formal treaty. [5. Two Key Elements of Customary Law] - Material Facts (State Practice) Customary law is based on the *actual practices of states*. This is the first requirement for identifying a customary rule---states must consistently engage in certain behaviors over time. - Psychological Element (Opinio Juris) The second essential element is known as *opinio juris sive necessitatis*, which is the belief by states that a certain practice is *legally obligatory*. This distinguishes customary law from mere social behavior, goodwill, or diplomatic courtesy. Without the belief that a practice is legally binding, the behavior cannot be considered customary law. For instance, states may grant asylum to refugees not because they are legally bound to do so, but as a matter of goodwill. [6. The Role of Opinio Juris] The relative importance of *state practice* (material element) *and opinio juris* (psychological belief) has been a subject of dispute among legal scholars: - *Positivist Scholars* argue that opinio juris is the critical element in establishing customary law. For them, states are bound by customs they believe are legally obligatory, even if these practices are only undertaken once. They stress *that state consent* is central to the creation of customary law, and they often downplay the need for repetition or long-standing practice. - *Other Scholars* contend that opinio juris is difficult to prove and should not be given too much weight. For example, *Hans Kelsen* argued that the role of courts, not states\' subjective beliefs, should determine whether a practice constitutes a customary rule. **The Material Fact in Customary International Law** The *material fact refers to the actual practice or behavior of states*, which is the initial factor in establishing customary international law. This involves evaluating various aspects of state behavior, such as its *duration, consistency, repetition, and generality.* [Duration of Practice] In International law, there is no rigid time requirement. The duration of a practice is context-dependent and varies according to the nature of the issue at hand. In some areas, such as air and space law, customary rules have developed quickly, while in other domains, the process is slower. Thus, *duration* is not the most important element in the formation of customary law. [Continuity and Repetition] - *Continuity and repetition* of state practices are crucial elements in forming customary law. The *Asylum Case* (1950) illustrates this. The International Court of Justice (ICJ) emphasized that for a practice to become customary law, it must be \"in accordance with a constant and uniform usage practiced by the states in question.\" The case involved the issue of asylum for a political refugee, and the ICJ noted that the practice of granting asylum was inconsistent among states, making it insufficient to establish a customary rule. - The *Anglo-Norwegian Fisheries* case reinforced the idea that a custom requires *uniformity* in state behavior. In this case, the ICJ rejected the idea that a specific practice regarding the measurement of territorial waters constituted customary law, as the practice lacked sufficient uniformity among states. - The *North Sea Continental Shelf case* (1969) reiterated that state practice must be \"extensive and virtually uniform\" for it to form customary international law. [Speed of Formation:] In certain fields, customary law can develop rapidly. This is often seen in newly emerging areas like space law, where the novelty of the issues, the lack of established rules, and the need for regulation can lead to a quicker formation of customary law. The ICJ in *Nicaragua v. United States* emphasized that new areas of law can evolve swiftly through state practice, especially when no contrary rules exist and there is a clear need for regulation. [Analogy of Custom Formation] - *De Visscher used an analogy of a road across vacant land* to describe the gradual process of custom formation. Initially, there is uncertainty, but as more states engage in a particular practice, it becomes more clearly defined, much like the creation of a recognized road. Over time, as more states follow this path, the practice solidifies into customary law, though pinpointing the exact moment this transformation occurs can be difficult. - This analogy also highlights that *influential states* play a more significant role in shaping customary law. Just as larger footprints make a more significant mark on the road, powerful states can more effectively establish customary rules. For example, *maritime nations* have historically shaped *sea law*, and similarly, the *United States and \*Soviet Union* (now Russia) have been central in developing *space law.* [Role of Powerful States] In international law, custom often reflects the *interests of major powers*. While all states may theoretically contribute to the development of customary law, the views and actions of influential states tend to carry more weight. For instance, a rule regarding the breadth of the *territorial sea* is unlikely to be considered customary law unless *major maritime nations* support it, regardless of how many landlocked nations advocate for it. This influence of powerful states is especially evident in areas where those states have a direct and vested interest. This often leads to the formation of customs that reflect the priorities of the most influential states in that particular domain. [Failure to Act] The question arises as to the significance of a *failure to act* by a state. Can a failure to participate in a practice be seen as acquiescence to that practice? The answer depends on the context and the state\'s awareness of its legal obligations. A failure to act may either reflect a legal obligation not to act or simply the incapacity or unwillingness of the state to take action. - In the *Lotus Case*(1927), the Permanent Court of International Justice stated that a failure to act could only create a customary rule if it was based on a *conscious duty* not to act. In other words, states must be aware that they are not acting because they are legally obligated to refrain from doing so. However, this decision has been criticized, and it is argued that *tacit acceptanc*e of a rule through inaction can also indicate recognition of that rule. - *Acquiescence* must be based on the *full knowledge* of the relevant circumstances. If a state fails to act due to a lack of awareness, it cannot be interpreted as tacit consent. Thus, the failure to act is significant, but its meaning depends on whether the state is aware of its obligations and whether it recognizes the legality of the practice. **State Practice and Its Role in Customary International Law** [What is State Practice?] - State practice refers to the actual behavior of states that can contribute to the formation of customary international law. It involves a broad range of state activities, including formal acts, informal statements, and other interactions within the international sphere. State practice is the foundation upon which customary law is built, as it reflects how states conduct themselves in international relations. - State practice is not limited to *positive actions*(such as official conduct or decisions) but can also include *statements, speeches, informal documents*, and *governmental pronouncements.* It represents how states behave, and this behavior is captured through various sources of evidence. [Sources of State Practice] Evidence of state practice can be obtained from numerous sources: - Official Documents and Actions legislative acts, court decisions, and administrative acts, as well as diplomatic activities like treaty-making. - Publications and Historical Records Newspapers, government reports, historical records, and official publications are crucial in understanding state behavior. - Diplomatic and Legal Exchanges Statements from governmental officials, diplomatic notes, and the opinions of national legal advisors also contribute to identifying state practice. - Resolutions and Decisions Resolutions in international bodies (e.g., the UN General Assembly) and decisions by international courts or organizations (such as the International Court of Justice) can provide insight into customary law. - International Organizations The actions and policies of international organizations can also be considered state practice, as they often reflect the behavior of member states. For example, the UN's Advisory Opinion on its international personality was partly based on the UN\'s own practice. - State practice is not limited to a state\'s official acts but can also be inferred from the interactions and claims made by states in various contexts, including treaties, statements, and even counterclaims in international disputes. These claims contribute to shaping customary law as they reflect the state\'s understanding of international norms. [Municipal Laws as State Practice] In some cases, municipal (domestic) laws can contribute to the formation of customary international law. For example, in the *Scotia case* (1871), the U.S. Supreme Court found that British navigational procedures, which had been legislated in domestic law, formed the basis of international customary law. The fact that other states had similar laws indicated a widely accepted custom. Thus, *national legislation* can sometimes be seen as evidence of broader international practices. [Claims vs. Physical Acts] A debate exists around whether mere *claims* by a state (rather than actual physical acts) can be considered part of state practice. Some argue that claims, in the absence of enforcement action, have little value. However, this view is not widely accepted. Claims and declarations made by states (even if they are not immediately enforced) are still seen as important indicators of the state's perception of customary law. *Claims and counterclaims* are methods by which states communicate their interpretation of international norms, and they can contribute significantly to shaping customary law. [Weight of State Practice] While state practice includes a broad range of acts and statements, not all acts are of equal weight in establishing customary law. The *nature and provenance* of state practice matter. For example, the actions of *major powers* or influential states in a particular area of law may carry more weight than those of smaller or less influential states. The *context* in which state practice occurs, such as in *treaty negotiations* or *diplomatic exchanges*, also influences how much value is attached to a particular practice. In sum, state practice encompasses a wide array of behaviors, both formal and informal, and is vital in determining customary international law. Claims, statements, and actual actions all play a role in demonstrating how states behave and perceive international legal norms. **Opinio Juris and Its Role in Customary International Law** [What is Opinio Juris?] Opinio juris refers to the belief or conviction that a particular state practice is legally obligatory. It is the psychological element that transforms a consistent and widespread practice into customary international law. Essentially, for a state's behavior to become part of customary law, the state must act under the belief that it is legally required to do so. Without this belief, the action remains a political or moral act, not a legal one. [The Lotus Case and Opinio Juris] The importance of *opinio juris was clearly articulated in the Lotus case*(1927), where the Permanent Court of International Justice (PCIJ) dealt with the question of whether Turkey could arrest a French officer following a ship collision on the high seas. The Court explained that for a practice to be recognized as customary international law, it must be accompanied by opinio juris---a belief that the practice is legally binding. This subjective element is crucial because it distinguishes legal acts from those that are simply political or moral gestures. [Opinio Juris in Customary Law Formation] For a new rule of customary law to emerge, two components are necessary: - State practice This refers to the consistent and widespread behavior of states. - Opinio juris States must engage in the practice with the belief that they are legally obligated to do so. - In the *Nicaragua case* and other rulings, the International Court of Justice (ICJ) emphasized the importance of the opinio juris element in determining whether a practice is legally obligatory. This means that the actions of states must be viewed as evidence that they believe such actions are required by international law. [The Challenge of Creating New Customary Rules] - A key issue with opinio juris is that it requires states to behave in accordance with existing law. However, when new customary rules are being created, this can lead to a conflict: how can states act in ways that go against established norms if they are supposed to believe they are legally required to act within existing law? For example, if a state claims a twelve-mile territorial sea, while the customary law previously recognized a three-mile limit, how can the new claim be recognized as legal under opinio juris? - The solution is that states may begin to act in a manner that they believe is lawful, even if it contradicts the existing customary law. If other states recognize and accept this behavior, the new practice may evolve into customary law. However, if other states reject it, the rule may not gain legitimacy, and the old norm remains intact. [The Flexibility of Opinio Juris] Given that customary law evolves over time, the understanding of opinio juris must be flexible. States may act in ways that challenge existing law, but their actions may reflect a belief that the law is changing. This tension is part of the dynamic nature of customary law. For example*, Judge Tanaka\'s Dissenting Opinion in the North Sea Continental Shelf cases* highlighted the idea that opinio juris can be inferred from the practice itself, without requiring evidence of the subjective motives behind each act. This approach allows for the recognition of evolving practices as part of customary law, even when there is not direct evidence of states\' beliefs. [The Role of International Organizations] In practice, proving the existence of opinio juris can be difficult, especially since states rarely declare that they are acting out of a belief in legal obligation. To address this, international organizations, particularly the *United Nations*, have become *important sources of evidence for opinio juris*. For example, the ICJ has referenced *General Assembly resolutions* and other UN actions as indications of opinio juris. The conditions under which these resolutions were adopted and the attitudes of states involved in them can reveal whether a particular practice is viewed as legally binding. **Protest, Acquiescence, and Change in Customary International Law** [Role of Protest and Acquiescence] Customary international law evolves through a pattern of claims, protests, acquiescence, and state behavior. Key elements in this process include: - Protest Acts or declarations by states objecting to certain behaviors or claims made by others. Protests serve to prevent the silent acceptance of a practice, which might otherwise evolve into a customary rule. - Acquiescence The failure to protest or object, which can be interpreted as tacit recognition or consent to the legitimacy of a state's actions. - Acquiescence is often seen as reinforcing emerging norms, particularly in new or developing areas of international law, like space law. However, when acquiescence involves deviation from established customs, it becomes more contentious. [Custom Formation Through Silence] The absence of protest can contribute to the creation of new customary rules. If a state asserts a particular behavior as lawful, and others do not object, this silence can be interpreted as agreement (opinio juris). However, this requires the assumption that states are aware of and capable of responding to such assertions, which is not always the case. As seen in the *Lotus case*, the ICJ held that abstention from an activity must stem from a sense of legal obligation for it to establish a prohibition in customary law. Silence alone is insufficient unless it reflects an implicit belief in the legal validity of the claim. [The Anglo-Norwegian Fisheries Case] Highlighted a significant point: a state that consistently objects to an emerging customary rule from its inception *(a persistent objector*) is not bound by it. In this case, Norway successfully argued against the applicability of a rule due to its longstanding opposition to its application on its coasts. This principle provides flexibility for dissenting states, but widespread acquiescence or support by others can override such objections and lead to the establishment of new norms. [Complexities in Protest and Acquiescence] States may choose not to protest for reasons unrelated to legal recognition, such as political strategy, diplomatic courtesy, or resource constraints. For example: - States may refrain from objecting to avoid diplomatic tensions. - Formal protests may serve as political pressure without intending to alter legal norms. - States might not have the resources to monitor and protest every emerging practice. This complexity underscores that not all silence equates to acquiescence. Interpreting non-reaction requires careful consideration of context and intent. [Change in Customary Rules] The evolution of customary law often involves conflicts between existing and emerging rules: - Emerging Rules Behavior that contradicts established norms may eventually lead to the formation of new rules if endorsed by a majority of states. - Coexisting Customs For some time, conflicting customs may coexist, as was the case with territorial sea limits before the acceptance of a twelve-mile limit. The protests of a few states may result in exceptions rather than invalidating an emerging rule, particularly if most states acquiesce to the new practice. [Customary Law and New States] Newly independent states pose a unique challenge to customary law. According to the traditional view, such states inherit the body of existing customary law. However, the *consent theory* suggests that new states should have the freedom to choose which customs to adhere to, potentially leading to significant disruptions in international law. To mitigate this, it is generally accepted that new states, by engaging in international relations, signal their acceptance of prevailing customs unless explicitly stated otherwise. **Regional and Local Custom in International Law** [Definition and Scope] Regional and local customs refer to rules that bind a specific group of states or even just two states, diverging from the general norms of international customary law. These customs may emerge due to shared legal traditions, geographical proximity, or unique historical relationships. - Examples include: - Regional customs Norms specific to a group of states, such as those in Latin America. - Local customs Norms binding only two states, based on their specific interactions and agreements. This framework reflects the importance of recognizing regional diversity and respect for specific legal traditions. [Legal Requirements for Regional and Local Customs ] The establishment of a regional or local custom imposes a *higher standard of proof* compared to general customary law. This is because such customs are exceptions to the general principle of universal applicability. The requirements include: - Established Practice A clear, consistent, and uniform practice between the states or within the region. - Acceptance as Law (opinio juris) Evidence that the states involved recognize the practice as a legal obligation. The *burden of proof* lies on the party asserting the existence of such a custom, and they must demonstrate that all relevant states have explicitly or implicitly accepted it as binding. [Case Law Examples] - The Asylum Case (Colombia v. Peru) In this case, Colombia argued for a *regional custom* in Latin America that supported its right to grant diplomatic asylum. The ICJ ruled against Colombia, stating that : The evidence of such a custom was inconsistent and contradictory. Colombia failed to prove that the alleged custom was binding on Peru. This case highlights the stricter evidentiary requirements for regional customs and the need for clear acceptance by all relevant parties. - The Right of Passage Case (Portugal v. India) Portugal claimed a *local custom* with India that granted it the right of passage through Indian territory to access its enclaves. The ICJ upheld Portugal's claim, reasoning that: - A *constant and uniform practice* of free passage had existed historically. - Both states had accepted this practice as a legal right and obligation. The Court emphasized that where specific bilateral practices are accepted as law, they can override general customary rules. [Key Principles of Regional and Local Custom] - Consent-Based Binding Nature Unlike general customs, which may bind states universally through broad acceptance, regional and local customs require *explicit acceptance* by all relevant parties. This aligns with the traditional principle of consent in international law. - Higher Evidentiary Threshold The proof must demonstrate - A consistent and uniform practice - Legal recognition and acceptance by all states involved. [Specificity and Supremacy] When established, regional or local customs take precedence over general international rules between the states concerned. This was articulated in them*Right of Passage* case, where the ICJ gave decisive weight to the bilateral practice over broader norms. **Treaties as a Source of International Law** [Definition and Role] Treaties are formal written agreements between states (or international entities) that create legally binding obligations. They are an explicit and deliberate method of creating international law, differing from the gradual and implicit nature of customary law. - Treaties may take various forms, including conventions, pacts, charters, declarations, and covenants, but they all serve the function of codifying agreed-upon norms and obligations. - The principle of *pacta sunt servanda*(\"agreements must be kept\") underscores their binding nature under international law [Types of Treaties] Treaties are often categorized based on their scope and purpose: - Law-Making Treaties: - These are intended to have universal or broad relevance, creating general norms of conduct. - Examples: - Charter of the United Nations Establishes the framework for international peace and security. - Genocide Convention Codifies obligations to prevent and punish genocide. - Treaty-Contracts - These apply only between specific parties, often addressing particular issues. - Examples: Agreements regulating shared resources or bilateral trade deals. While not law-making instruments, treaty-contracts may provide evidence of emerging customary rules. [Treaties and Customary Law ] Treaties interact with customary international law in several ways: - Codification of Custom Treaties like the *Vienna Convention on Diplomatic Relations* often codify pre-existing customary norms. These treaties help clarify and formalize the rules for consistent application. - Generation of New Customary Law Treaty provisions can evolve into customary law if they exhibit a \"fundamentally norm-creating character,\" as noted in the North Sea Continental Shelf Cases - This occurs when: - The treaty is widely adopted. - States behave consistently with its provisions, coupled with opinio juris. - For example, provisions of the *Geneva Conventions* have influenced the development of humanitarian customary law. - Coexistence of Custom and Treaty Law A customary rule and treaty rule on the same subject can coexist. In the Nicaragua Case, the ICJ held that customary norms on self-defense existed independently of Article 51 of the UN Charter. - This dual existence ensures that even non-parties to a treaty may still be bound by overlapping customary norms. [Non-Parties and the Effect of Treaties] - Treaties generally bind only the parties that have signed and ratified them. - However, treaties may affect non-parties in certain situations: - Reflecting Customary Law If a treaty codifies or generates customary law, its norms bind non-parties through custom. - Constitutive Treaties Certain treaties establish regimes or institutions with global implications, such as the UN Charter or GATT (now WTO). - Influence on Practice Non-party states may adopt treaty provisions as a matter of policy or practice, further reinforcing their normative weight. [Interpretation and Application ] Treaties must be interpreted based on their text, context, and purpose, with guidance from the Vienna Convention on the Law of Treaties (1969). They may function as: - Normative Frameworks Setting rules for state behavior (e.g., Antarctic Treaty). - Constitutive Instruments Establishing international organizations and defining their mandates (e.g., WHO, IMF). [Importance of Treaties in Modern International Law ] - Treaties have become essential tools for regulating a diverse range of issues, from human rights to trade, environmental protection, and arms control. Their explicit and consent-based nature ensures clarity and predictability in international relations. - Examples of significant treaties include: - Paris Agreement Addressing climate change. - Geneva Conventions Establishing standards for humanitarian treatment in war. - Outer Space Treaty Governing activities in outer space. [Challenges and Considerations] - Limited Participation A treaty\'s impact is constrained by the number of parties, with non-parties potentially undermining its universality. - Conflicts with Customary Law Divergences between treaty norms and custom can complicate their interpretation and application. - Risk of Overreach As noted in discussions of norm-creating treaties, the possibility of a small group of states dictating norms for all is a concern, particularly if dissenting states are marginalized. **General Principles of Law in International Law** [Introduction ] General principles of law serve as a critical source of international law, bridging gaps when neither treaties nor customary law provide guidance. These principles, derived from the common foundations of domestic legal systems, allow courts to resolve issues that international law does not explicitly address, ensuring that the legal framework remains effective and responsive. [Role and Scope ] - Foundation of General Principles In domestic law, courts often deduce rules based on overarching legal principles like justice, equity, or public policy when faced with gaps. Similarly, international law relies on general principles to address its underdeveloped nature compared to domestic systems. - Legal Basis Article 38(1)(c) of the Statute of the International Court of Justice (ICJ) explicitly includes \"general principles of law recognized by civilized nations\" as a source of international law. These principles close legal gaps and address non liquet (situations where no law applies). - Sources of Principles While the principles are inspired by domestic laws, they do not replicate specific national legal systems. Instead, they reflect concepts common across diverse legal traditions, such as common law, civil law, and customary systems. [Application in Case Law ] - Reparation and Responsibility In the *Chorzów Factory Case* (1928), the Permanent Court of International Justice (PCIJ) articulated a key principle: violations of legal obligations entail a duty of reparation. This notion underpins the obligation of states to indemnify for wrongful acts, echoing a near-universal norm in municipal systems. - Rights and Sovereignty Changes The *German Settlers in Poland Case* highlighted the continuity of private rights despite changes in sovereignty, rejecting the idea that such rights perish without legal justification---a principle widely recognized in national legal orders. - Procedural and Evidentiary Rules *Corfu Channel Case*, the ICJ emphasized that indirect evidence (circumstantial evidence) is admissible across legal systems. The principle of res judicata (finality of judicial decisions) was affirmed in cases like the *Administrative Tribunal Case and the Bosnia Genocide Case*, emphasizing the need for stability in legal relations and the finality of judgments - Estoppel The doctrine of estoppel, which prevents a party from denying facts or rights it previously acknowledged to the detriment of others, has been applied in cases such as the *Temple Case*. However, the ICJ has cautioned against its indiscriminate use, as noted in *ELSI and Cameroon v. Nigeria.* - Compensation Principles The principle that damages should include *damnum emergens*(actual loss) and *lucrum cessans* (lost profit) has been recognized as a general principle in cases like *AMCO v. Republic of Indonesia* [Core Principles in International Law ] - Pacta Sunt Servanda The principle that treaties are binding forms the cornerstone of international treaty law. It ensures that international agreements are honored and enforceable. - Good Faith Recognized as a universal principle, good faith governs the creation and performance of obligations. It is enshrined in Article 2(2) of the UN Charter and was reaffirmed in the \*Nuclear Tests Cases\*. However, it does not create obligations where none exist, serving instead to inform and constrain the application of existing rules. - Ex Injuria Jus Non Oritur This principle establishes that legal rights cannot arise from wrongful acts, ensuring that unlawful actions do not confer legitimacy or benefits. - Acquired Rights and Stability The protection of acquired rights reflects a general principle of continuity and stability, ensuring that legal transitions do not unfairly disrupt established rights. **Judicial Discretion and Practicality** The ICJ and other international tribunals exercise discretion in applying general principles, often relying on analogies to domestic legal systems. For instance, in the Barcelona Traction Case, the ICJ referenced the concept of limited liability from municipal law to address gaps in international legal doctrine. **Chap 12 -- Jurisdiction** **Jurisdiction in International Law** Jurisdiction is a cornerstone of state sovereignty, embodying the authority of a state to regulate people, property, and activities under its control. This authority is manifested through legislative, executive, and judicial actions and is governed by principles of sovereignty, equality of states, and non-intervention. [Types of Jurisdiction ] - Prescriptive Jurisdiction Refers to the authority to make laws, whether through legislation, executive orders, or judicial rulings. Example: In the UK, Parliament enacts statutes that bind citizens and entities within the state. - Enforcement Jurisdiction Involves ensuring compliance with laws through administrative or coercive measures. Example: Law enforcement agencies executing legal mandates within the state's territory. - Adjudicative Jurisdiction Refers to the power of courts to resolve disputes and deliver binding judgments. [Jurisdiction in International Law vs. Private International Law ] - International Law - Focuses on the relations between states and the exercise of jurisdiction based on principles like sovereignty and equality. - Includes territorial jurisdiction, nationality-based jurisdiction, and universal jurisdiction (e.g., addressing crimes like piracy) - Private International Law: - Governs conflicts of laws in cross-border private disputes. - Determines which state has jurisdiction to hear a case and which country's laws apply. - Grounds often include domicile, residence, or contractual agreements. [Principle of Domestic Jurisdiction ] State Sovereignty and Non-Intervention A state has supreme authority within its borders, and other states must not interfere in its internal affairs. Examples Determining conditions for granting nationality / Setting rules for the entry and residence of foreign nationals. Erosion by International Law Domestic jurisdiction is increasingly influenced by international legal norms, especially in areas like human rights.Example: The treatment of a state's nationals is now subject to scrutiny under international human rights conventions. Case Law *Anglo-Norwegian Fisheries Case* (1951) Territorial water delimitation, while a unilateral act, must conform to international law. *Nottebohm Case* (1955) Nationality rules are domestic, but their international effects, like diplomatic protection, fall under international law. States cannot cite domestic law to justify breaches of international obligations. [UN Charter and Domestic Jurisdiction ] - Article 2(7) - Prohibits UN intervention in matters within a state's domestic jurisdiction unless international peace and security are at stake. - Despite this, the UN has increasingly engaged with issues traditionally considered domestic, such as: - Decolonization Encouraging self-determination and independence during the mid-20th century. - Human Rights Criticizing policies like apartheid in South Africa and supporting broader human rights frameworks. - Expansion of UN Concern Over time, international practice has further narrowed the scope of purely domestic jurisdiction, demonstrating the interplay between sovereignty and global accountability. [Limits and Flexibility of Domestic Jurisdiction ] - Relative Nature - The boundary between domestic and international jurisdiction is fluid and evolves with global norms. - For instance, while territorial sovereignty is fundamental, its exercise is constrained by international obligations, such as respecting neighboring states\' rights. - Balancing Sovereignty and International Obligations - Sovereignty remains a foundation of international law, but it operates within an interconnected global system where states must navigate competing priorities. [Legislative, Executive, and Judicial Jurisdiction] - Legislative Jurisdiction - Definition Legislative jurisdiction refers to the power of a state's constitutionally recognized organs to enact binding laws within its territory. - Key Feature - Territorial Supremacy States have the exclusive right to legislate within their borders. For example, they can establish procedural rules for their courts and administrative bodies. However, they cannot dictate how foreign courts or entities operate. - Example: A UK court may reject a foreign court\'s judgment for bias, but the UK cannot impose procedural changes on foreign courts. - Extraterritorial Application: - States can extend legislative jurisdiction abroad in specific circumstances. - Example: Taxation of citizens or entities based on nationality, domicile, or another \"real link,\" even if they reside abroad. - Limitations - Laws that affect foreign-owned property abroad are unenforceable unless backed by international consensus. - States are prohibited from enacting laws that contravene international law, such as discriminatory treatment of foreign nationals or their property. - Abuse of legislative jurisdiction, like compelling nationals abroad to follow domestic regulations (e.g., mandating French citizens abroad to drive French cars), infringes on the sovereignty of other states. [International Law Constraints ] - Breaches of international law by legislation may result in protests or actions from other states. - Prescriptive jurisdiction (the capacity to enact laws) must align with international norms to avoid conflicts with other nations\' sovereignty. [Executive Jurisdiction ] - Definition Executive jurisdiction refers to a state\'s capacity to enforce its laws or take official action, typically within its territory. - Key Features - Territorial Boundaries State officials cannot perform governmental actions on foreign soil without explicit consent. - Example: A state's police cannot apprehend suspects in another state without permission. - Prohibited Actions Unauthorized enforcement of laws or apprehension of persons/property in another state violates international law. - Example: The abduction of Adolf Eichmann by Israeli agents from Argentina in 1960 breached Argentina's territorial sovereignty. - Exceptions Actions may be permissible with express consent from the host state - Example: Cooperation agreements in criminal investigations, such as extradition treaties. - Military Interventions Unauthorized military actions, such as invasion or intervention, constitute clear breaches of international law. [Judicial Jurisdiction ] - Definition Judicial jurisdiction concerns the authority of a country's courts to hear and adjudicate cases involving foreign elements. - Key Features - Grounds for Exercising Jurisdiction: - Territorial Principle Jurisdi
