Chapter IV of the United Nations Charter

Chapter IV of the United Nations Charter contains the Charter's provisions dealing with the UN General Assembly, specifically its composition, functions, powers, voting, and procedures.
Primacy of the General Assembly.
The chapter on the UN General Assembly appears in the Charter before the chapters on the other five principal organs (UN Security Council, UN Economic and Social Council, Trusteeship Council, International Court of Justice, and UN Secretariat). This reflects the UN's founders' view of the General Assembly as the "first" branch of the UN, in much the same way that the placement of the provisions related to the United States Congress in Article One of the United States Constitution before those dealing with the US president and US Supreme Court reflects the Philadelphia Convention's view of Congress as the "first branch" of the US government. Both the US Congress and the UN General Assembly hold the "power of the purse" in regard to their respective organizations. No doubt, the General Assembly also appears first because most decisions (except those dealing with security matters) mentioned later in the Charter require General Assembly assent, and the General Assembly appoints:
Article 9 guarantees each member country a seat in the General Assembly, making it the only UN body with universal membership.
Articles 10, 11, 12, 13, 14, 15, and 16.
Article 10 gives the General Assembly (UNGA) power to "discuss any questions or any matters within the scope of the present Charter or relating to the powers and functions of any organs provided for in the present Charter" and to make recommendations on those subjects. This, along with the Article 15 provision requiring the Security Council (UNSC) and other organs to issue reports of their activities to the General Assembly, essentially puts the General Assembly in the role of overseer over the other UN bodies (there is no reciprocal provision by which the Security Council or other bodies make recommendations as to the powers and functions of the General Assembly). Article 11 tasks the UNGA with considering "principles governing disarmament and the regulation of armaments" and making recommendations on the same to the UNSC, which under Chapter V has the responsibility of making more detailed plans in reference to disarmament. The UNGA is prohibited by Article 12 from making recommendations on matters currently being dealt with by the UNSC, unless requested to do so by the council. However, this has not always prevented the General Assembly from attempting to deal with threats to international peace and security, in cases where the UNSC was deadlocked, by using the framework of the Uniting for Peace resolution (A/RES/377 A).
Article 13 tasks the General Assembly with initiating studies and making recommendations for "promoting international co-operation in the political field and encouraging the progressive development of international law and its codification." This provides a clue as to the founders' hopes that the UN as formulated by the original Charter would be a first step toward a much more comprehensive framework of international law, whose development would be coordinated by the General Assembly. Article 16 grants the UNGA limited power over the trusteeship system.
Article 17.
Article 17 provides that "The General Assembly shall consider and approve the budget of the Organization." The interpretation of section 2 is controversial. It reads:
When the United States fell behind in paying its dues to the UN, some members held that the US was breaking its treaty obligations to bear the expenses of the Organization. In 1995, Malaysia said that any unilateral decision to reduce UN assessments is "illegal and totally unacceptable" and Australia said it "would not accept" a situation whereby "the largest contributor, by it failure to comply with the Charter, would destabilize the operation of the UN". Another interpretation, advanced by the Cato Institute, is that "the intent is to make certain that the world body is financed by countries, not special interests outside the organization".
Article 18.
Article 18 gives each state one vote in the UN General Assembly. The interpretation of Sections 2 and 3 are controversial. They read:
The question of what constitutes an "important question" arose during the discussion of General Assembly Resolution 2758, which expelled the Taiwanese delegation from the UN and replaced it with the People's Republic of China. The General Assembly had declared, by a vote of 59 to 55 with 15 abstentions, this to be an unimportant question that did not require the consent of two-thirds of the members. The delegates of the Republic of China protested that this decision was illegal, and subsequently left the assembly hall.
Article 18 was designed to provide a more workable system than that established by Article 5 of the Covenant of the League of Nations, which provided for a consensus-based system in which "decisions at any meeting of the Assembly or of the Council shall require the agreement of all the Members of the League represented at the meeting."
Article 19.
Article 19 provides that any country that falls two years behind in its dues will lose its vote in the General Assembly. The United States, when it was withholding dues in protest over the slow pace of UN reform, has historically paid just enough at the end of each year to avoid losing its vote under this provision.
Rule 161 of the rules of procedure of the General Assembly states that the Committee on Contributions shall "advise the General Assembly ... on the action to be taken with regard to the application of Article 19 of the Charter".
According to the "New York Times", "The fact that a member is in arrears and thus not entitled to vote is, by established practice, determined by the Secretary General through computation and reported to the Assembly by him or by the Committee on Contributions. Comparable situations in specialized agencies of the United Nations have shown that a member's loss of voting rights is mandatory and automatic and that the fact of his debt is a 'ministerial, mathematical calculation' rather than a political decision."
After a World Court ruling in the "Certain Expenses" case made it clear that Soviet and Soviet bloc countries, France, and Latin American countries had defaulted on peacekeeping debts, during the 19th session (1964-1965), no votes at all were taken in the General Assembly. It was ultimately decided to ignore that default rather than take away those countries' vote in the General Assembly. U.S. Ambassador Arthur Goldberg declared that "it is not in the world interest to have the work of the General Assembly immobilized in these troubled days."
In 1963, an announcement of Haiti's arrears by the president of the General Assembly at the opening plenary meeting was considered unnecessary because a formal vote count in the presence of a representative of Haiti did not take place.
Circa 1969, the government of Haiti claimed it was unable to pay its dues due to cyclones Betty, Flora, and Ines, which over a period of seven years destroyed half its agriculture, its livestock, and its light industry. Haiti also cited the negative effects on tourism of invasions such as the 20 May 1968 invasion.
As of late April 1998, 29 UN member countries were in arrears by more than their preceding two years' assessments and thus were ineligible to vote in the General Assembly. In 1999, faced with the possibility of Article 19 sanctions, President Bill Clinton agreed to withhold funding from organizations that supported abortion in exchange for Congress's agreement to repay U.S. arrears to the United Nations.
Article 22.
Article 22 allows the UN to establish subsidiary bodies. This has been the basis for proposals to establish a United Nations Parliamentary Assembly without formal amendment of the UN Charter.
