Detailed Study Notes for Unit V

Unit-V: International Organizations, UN, ICJ, ICC & Specialized Agencies

1. International Organizations: League of Nations and United Nations

A. The League of Nations (1920)

Origin & Purpose: Established via the Treaty of Versailles following World War I, it was the first worldwide intergovernmental organization whose principal mission was to maintain global peace and collective security.
Structural Failures: Lacked universal membership (the US never joined), required unanimous voting on major security issues, and lacked an effective enforcement mechanism or military force, leading to its inability to prevent Axis aggression and World War II.

B. The United Nations (UN), 1945

Origin: Formed in the aftermath of WWII via the UN Charter (signed in San Francisco on June 26, 1945) to save succeeding generations from the scourge of war.
Principal Organs of the UN:
1. General Assembly (UNGA): The deliberative, policymaking, and representative organ consisting of all 193 member states, operating on a one-nation, one-vote principle.
2. Security Council (UNSC): Charged with primary responsibility for maintaining international peace and security. Consists of 15 members (5 permanent members with veto power: USA, UK, France, Russia, China; and 10 non-permanent members elected for two-year terms).
3. Economic and Social Council (ECOSOC): Coordinates economic, social, and environmental work of UN specialized agencies.
4. Trusteeship Council: Promoted the advancement of trust territories toward self-government or independence (operationally suspended in 1994).
5. Secretariat: Administrative organ headed by the UN Secretary-General.
6. International Court of Justice (ICJ): The principal judicial organ of the UN.

2. The International Court of Justice (ICJ)

Nature & Status: Often called the “World Court,” located in The Hague (Netherlands). It functions in accordance with its Statute, which is an integral part of the UN Charter.
Composition: Comprises 15 judges elected for 9-year terms by the UN General Assembly and Security Council, ensuring representation of the principal legal systems of the world.
Jurisdiction of the ICJ:
1. Contentious Jurisdiction: Resolves legal disputes submitted voluntarily by sovereign states. Only states may be parties in cases before the Court (individuals and NGOs lack standing). Jurisdiction depends on state consent (through special agreements, compromissory clauses in treaties, or optional clause declarations under Article 36(2)).
2. Advisory Jurisdiction: Gives advisory opinions on legal questions at the request of the UN General Assembly, Security Council, or authorized specialized agencies.

3. The International Criminal Court (ICC)

Establishment: Created by the Rome Statute (entered into force on July 1, 2002) as a permanent, treaty-based international criminal court. Unlike the ICJ (which tries states), the ICC tries individuals.
Jurisdiction (Core Crimes): Has jurisdiction over four grave international crimes:
1. Genocide
2. Crimes against Humanity
3. War Crimes
4. The Crime of Aggression
Principle of Complementarity: The ICC operates as a court of last resort. It does not replace domestic courts; it intervenes only when national legal systems are genuinely unwilling or unable to investigate or prosecute the crimes.

4. Specialized Agencies of the United Nations

Specialized agencies are autonomous international organizations linked to the UN through cooperative agreements, specializing in specific functional sectors:

World Health Organization (WHO): Directs and coordinates international health within the UN system, aiming for the attainment of the highest possible level of health by all peoples.
United Nations Educational, Scientific and Cultural Organization (UNESCO): Promotes international collaboration in education, arts, science, and culture to advance world peace and mutual respect.
International Labour Organization (ILO): A tripartite agency (bringing together governments, employers, and workers) devoted to setting international labour standards, promoting rights at work, and enhancing decent employment opportunities.
International Monetary Fund (IMF): Oversees the international monetary system, promotes global monetary cooperation, secures financial stability, and facilitates international trade.
World Trade Organization (WTO): Not strictly a traditional UN specialized agency, but the premier global international organization dealing with the rules of trade between nations, administering WTO trade agreements, and providing a platform for negotiating trade disputes.

5. In-Depth Landmark Case Studies

Case Study 1: ICJ Jurisdiction & Legality of the Use of Force

Case Title: Military and Paramilitary Activities in and against Nicaragua (Nicaragua v. United States of America)
Citation & Court: ICJ Reports 1986, p. 14 (International Court of Justice)
Related Statutory Sections: Article 36(2) of the ICJ Statute and Article 2(4) & 51 of the UN Charter.
The Story & Real-Life Background: Nicaragua initiated proceedings against the US before the ICJ, alleging that US intervention in mining Nicaraguan ports and supporting rebel contras violated international law and the UN Charter. The US challenged the jurisdiction of the court and argued its actions were collective self-defense.
Legal Issues Involved:
- Whether the ICJ has jurisdiction to adjudicate disputes involving armed conflict when a state has filed reservations to multilateral treaty declarations.
- The scope of the inherent right of individual and collective self-defense under Article 51 of the UN Charter.
Final Judgement & Ratio Decidendi:
- Ruling: The ICJ ruled that it possessed jurisdiction to hear the case on the basis of customary international law principles, even if specific multilateral treaty reservations applied. The court held that the US use of force against Nicaragua violated the customary international law prohibition on the use of force and non-intervention.
- Ratio: Customary international law rules retain a separate, autonomous existence alongside conventional treaty law, and the ICJ is fully competent to apply customary norms in state disputes.

Case Study 2: Legal Nature and Binding Force of ICJ Advisory Opinions

Case Title: Legality of the Threat or Use of Nuclear Weapons (Advisory Opinion)
Citation & Court: ICJ Reports 1996, p. 226 (International Court of Justice)
Related Statutory Sections: Article 65 of the ICJ Statute and Article 96 of the UN Charter.
The Story & Real-Life Background: The UN General Assembly formally requested an advisory opinion from the ICJ asking whether the threat or use of nuclear weapons is permitted under any circumstance in international law, given humanitarian law prohibitions against indiscriminate destruction.
Legal Issues Involved: Whether the ICJ should exercise its discretionary power to give an advisory opinion on political matters, and what rules of international humanitarian law govern the use of nuclear weapons.
Final Judgement & Ratio Decidendi:
- Ruling: The ICJ accepted the request and delivered its advisory opinion, concluding that while the threat or use of nuclear weapons would generally be contrary to the rules of international law applicable in armed conflict, the court could not definitively conclude whether such use would be lawful or unlawful in an extreme circumstance of self-defense where the very survival of a State would be at stake.
- Ratio: Advisory opinions, while lacking binding enforcement as a judgment between specific litigants, carry immense authoritative legal weight and clarify fundamental principles of international law.
