United Nations Charter

The United Nations Charter, signed on 26 June 1945 at the San Francisco Conference and entered into force on 24 October 1945, is the foundational treaty that creates the United Nations and delineates its purposes, principles, and institutional architecture. Comprising 111 articles organized into a preamble and fifteen chapters, the Charter codifies the post‑World‑War II vision of collective security, human rights, and economic development. Its uniqueness lies in establishing a permanent, legally binding framework for an intergovernmental organization whose authority derives directly from the consent of sovereign states. As the only international instrument that simultaneously defines the UN’s organs, decision‑making procedures, and the limits of state sovereignty, the Charter remains the cornerstone of modern international law. ## Origins and Historical Background The Charter emerged from the failure of the League of Nations and the urgency to prevent another global conflict after 1939‑1945. Delegates from 50 Allied nations convened in San Francisco from 25 April to 26 June 1945, where the United Nations Conference on International Organization drafted the text under the chairmanship of US Secretary of State Edward St. John Sullivan. The preamble’s phrase “We the peoples of the United Nations” reflects the shift from a state‑centric to a people‑centric conception of international order, a notion championed by British diplomat Sir Gladwyn Jebb. The final instrument was signed by representatives of the United States, United Kingdom, Soviet Union, China, and France—later recognized as the five permanent members of the Security Council. ## Structure and Mechanisms of the Charter Article 1 enumerates the UN’s four primary purposes: maintaining international peace and security, developing friendly relations among nations, achieving international cooperation in solving economic, social, cultural, and humanitarian problems, and being a centre for harmonising the actions of nations. The Charter creates six principal organs: the General Assembly (Article 10), the Security Council (Article 24), the Economic and Social Council (Article 55), the International Court of Justice (Article 92), the Secretariat (Article 97), and the Trusteeship Council (Article 86, now inactive). Decision‑making in the General Assembly follows a majority vote, whereas substantive resolutions of the Security Council require the affirmative vote of nine of fifteen members, including the concurrence of all five permanent members—a veto power codified in Article 27(3). The Secretariat, headed by the Secretary‑General appointed by the General Assembly on the Security Council’s recommendation, administers day‑to‑day operations and implements decisions across the UN system. ## Key Provisions Article 2 sets out the Charter’s core principles, notably the sovereign equality of all members (Article 2(1)), the prohibition of the use of force except in self‑defence or with Security Council authorization (Article 2(4)), and the obligation to settle disputes peacefully (Article 2(3)). Chapter VII (Articles 39‑51) empowers the Security Council to determine the existence of threats to peace and to impose sanctions or authorize collective military action, a mechanism invoked in the Korean War (Resolution 82, 1950) and the Gulf War (Resolution 678, 1990). Chapter IX (Articles 55‑60) establishes the Economic and Social Council, which coordinates specialized agencies such as the World Health Organization and the International Labour Organization. The Charter also obliges members to settle disputes through the International Court of Justice, whose jurisdiction is affirmed in Article 94, which requires states to comply with the Court’s judgments. ## Amendment and Legal Status Amendments to the Charter require a two‑thirds majority of the General Assembly and ratification by two‑thirds of the member states, including all permanent members of the Security Council, as stipulated in Article 108. To date, only five amendments have been adopted, all concerning the expansion of the Security Council and the Trusteeship Council’s functions. The Charter’s status as a treaty of international law grants it supremacy over subsequent UN resolutions, a principle affirmed by the International Court of Justice in the Reparations for Injuries (1949) case. Consequently, any UN action that contravenes the Charter can be challenged before the ICJ or invoked by member states as a breach of treaty obligations. ## Significance and Contemporary Relevance The Charter’s legal framework underpins the UN’s peacekeeping missions, humanitarian interventions, and development programmes, shaping the conduct of more than 190 member states. Its principle of collective security has evolved into doctrines such as the Responsibility to Protect, first articulated in the
