United Nations Charter

The United Nations Charter is the international treaty that established the United Nations and defines its purposes, institutions, powers, and the obligations of its member states. Signed in San Francisco on 26 June 1945, it entered into force on 24 October 1945. It is a binding instrument of international law, addressing international peace and security, cooperation, human rights, and the principles governing relations among states. The Statute of the International Court of Justice forms an integral part of the Charter. (un.org)

Origins and adoption

The Charter was drafted near the end of World War II. Its preparation developed through several wartime declarations and negotiations, including the Atlantic Charter of 1941 and the Declaration by United Nations of 1942. These initiatives provided a framework for creating an international organization dedicated to peace and cooperation. (un.org)

Representatives of 50 countries met at the United Nations Conference on International Organization in San Francisco from 25 April to 26 June 1945. The conference adopted the Charter unanimously on 25 June, and representatives signed it the following day. Poland, which was not represented at the conference, signed later and became one of the organization’s 51 original members. (un.org)

Entry into force required ratification by China, France, the Soviet Union, the United Kingdom, and the United States, together with a majority of the other signatories. This condition was fulfilled on 24 October 1945, the date on which the United Nations formally came into existence. (un.org)

Structure and purposes

The Charter consists of a preamble and 111 articles arranged in 19 chapters. It covers purposes and principles; membership; the principal organs; peaceful dispute settlement; enforcement action; regional arrangements; economic and social cooperation; non-self-governing and trust territories; legal and administrative provisions; amendment; and ratification. (un.org)

Article 1 identifies four central purposes:

• Maintaining international peace and security.
• Developing friendly relations based on equal rights and the self-determination of peoples.
• Promoting cooperation on economic, social, cultural, and humanitarian problems, together with respect for human rights.
• Providing a centre for coordinating national efforts toward these ends. (un.org)

Article 2 establishes the principles through which these purposes are to be pursued. These include the sovereign equality of members, fulfilment of Charter obligations in good faith, peaceful settlement of disputes, and assistance to United Nations action. Sovereign equality concerns the legal standing of states; the Charter nevertheless assigns different institutional powers to different members, notably in Security Council voting. (legal.un.org)

Article 2(4) prohibits the threat or use of force against another state’s territorial integrity or political independence, or otherwise inconsistently with United Nations purposes. Article 2(7) protects matters essentially within domestic jurisdiction from United Nations intervention, while expressly preserving Chapter VII enforcement measures. These provisions place both state sovereignty and international security within the Charter’s framework. (legal.un.org)

Membership and institutions

Article 4 opens membership to peace-loving states that accept Charter obligations and are judged able and willing to carry them out. Admission requires a decision of the General Assembly following a recommendation of the Security Council. Articles 5 and 6 provide procedures for suspending membership rights or expelling a member, also involving both organs. (un.org)

Article 7 establishes six principal organs:

The Charter also permits the establishment of subsidiary organs. (un.org)

The General Assembly may discuss matters within the Charter’s scope and make recommendations, subject to specified limitations. Its powers also include approving the organization’s budget. The Security Council occupies a distinct position: Article 25 requires members to accept and carry out its decisions in accordance with the Charter. Recommendations and binding decisions are therefore not interchangeable categories. (archives.gov)

Peaceful settlement, enforcement, and self-defence

Chapter VI governs peaceful dispute settlement. Article 33 requires parties to disputes likely to endanger international peace and security to seek solutions through negotiation, inquiry, mediation, conciliation, arbitration, judicial settlement, regional arrangements, or other peaceful means. The Security Council may investigate situations and recommend procedures or terms of settlement. (un.org)

Chapter VII provides for collective security action. Under Article 39, the Security Council determines whether a threat to peace, breach of peace, or act of aggression exists. Article 41 permits measures not involving armed force, including economic restrictions and interruption of diplomatic relations. Article 42 permits military action when the Council considers non-military measures inadequate. (un.org)

Article 51 recognizes the inherent right of individual or collective self-defence if an armed attack occurs against a United Nations member, until the Security Council has taken necessary measures. States exercising this right must immediately report their measures to the Council. The provision also preserves the Council’s continuing authority and responsibility for international peace and security. (legal.un.org)

Security Council voting

Article 27 gives each Security Council member one vote. Procedural decisions require nine affirmative votes. Decisions on other matters require nine affirmative votes and are subject to the special voting position of the five permanent members. A negative vote by a permanent member prevents adoption of a substantive decision—the mechanism commonly called the veto. (main.un.org)

Although the Charter’s wording refers to the permanent members’ concurring votes, established Council practice permits adoption when a permanent member abstains, provided the required affirmative votes are obtained. Consequently, abstention is not equivalent to a veto. Article 27 also requires a party to a dispute to abstain in certain decisions concerning peaceful settlement. (main.un.org)

Economic cooperation and territorial administration

The Charter’s remit extends beyond preventing armed conflict. Article 55 calls for higher living standards, full employment, economic and social progress, cooperation in health, culture, and education, and universal respect for human rights without specified forms of discrimination. Under Article 56, members pledge joint and separate action in cooperation with the organization to pursue these goals. (un.org)

Chapters XI–XIII address non-self-governing territories and the international trusteeship system. Article 73 requires administering states to regard inhabitants’ interests as paramount and to develop self-government. Article 76 identifies progress toward self-government or independence, according to the circumstances and wishes of the peoples concerned, among the trusteeship system’s objectives. These provisions form part of the legal framework associated with decolonization. (archives.gov)

Legal priority and amendment

Article 103 gives Charter obligations priority when they conflict with a member’s obligations under another international agreement. Its wording concerns conflicting obligations, rather than declaring every provision of every other treaty invalid. Article 102 separately requires registration and publication of treaties and international agreements; an unregistered agreement cannot be invoked before a United Nations organ. (un.org)

Under Article 108, amendments require adoption by two-thirds of General Assembly members and ratification by two-thirds of United Nations members, including every permanent Security Council member. Once effective, they apply to all members. Article 109 provides a separate review-conference procedure, but alterations recommended through it likewise require ratification that includes all permanent members. (legal.un.org)

The principal amendments have changed institutional size and voting thresholds:

• 31 August 1965: the Security Council expanded from 11 to 15 members, its principal affirmative-vote threshold increased from seven to nine, and the Economic and Social Council expanded from 18 to 27 members.
• 12 June 1968: the Security Council voting threshold for convening a Charter review conference under Article 109(1) increased from seven to nine.
• 24 September 1973: the Economic and Social Council expanded from 27 to 54 members. (un.org)

The Charter’s decision-making rules impose identifiable institutional limits: permanent-member opposition can block substantive Security Council decisions, and amendment cannot take effect without ratification by all five permanent members. These limits follow from the treaty’s voting and amendment provisions, rather than from a general power of the United Nations to compel agreement among its members. (main.un.org)
