The United Nation Organization has not been able fully to accomplish its goals in establishing peace in the world.The Charter of the United Nations was signed on 26 June 1945, in San Francisco, at the conclusion of the United Nations Conference on International Organization, and came into force on 24 October 1945. The Statute of the International Court of Justice is an integral part of the Charter. Membership in the United Nations is open to all other peace-loving states which accept the obligations contained in the present Charter and, in the judgment of the Organization, are able and willing to carry out these obligations.
The admission of any such state to membership in the United Nations will be effected by a decision of the General Assembly upon the recommendation of the Security Council. There are established as principal organs of the United Nations: a General Assembly, a Security Council, an Economic and Social Council, a Trusteeship Council, an International Court of Justice and a Secretariat.Such subsidiary organs as may be found necessary may be established in accordance with the present Charter.
The United Nations shall place no restrictions on the eligibility of men and women to participate in any capacity and under conditions of equality in its principal and subsidiary organs.
CHAPTER V: THE SECURITY COUNCIL COMPOSITION
The Security Council shall consist of fifteen Members of the United Nations. The Republic of China, France, the Union of Soviet Socialist Republics, the United Kingdom of Great Britain and Northern Ireland, and the United States of America shall be permanent members of the Security Council. The General Assembly shall elect ten other Members of the United Nations to be non-permanent members of the Security Council, due regard being specially paid, in the first instance to the contribution of Members of the United Nations to the maintenance of international peace and security and to the other purposes of the Organization, and also to equitable geographical distribution. The non-permanent members of the Security Council shall be elected for a term of two years. In the first election of the non-permanent members after the increase of the membership of the Security Council from eleven to fifteen, two of the four additional members shall be chosen for a term of one year. A retiring member shall not be eligible for immediate re-election.Each member of the Security Council shall have one representative.
FUNCTIONS and POWERS
In order to ensure prompt and effective action by the United Nations, its Members confer on the Security Council primary responsibility for the maintenance of international peace and security, and agree that in carrying out its duties under this responsibility the Security Council acts on their behalf. In discharging these duties the Security Council shall act in accordance with the Purposes and Principles of the United Nations. The specific powers granted to the Security Council for the discharge of these duties are laid down in Chapters VI, VII, VIII, and XII. The Security Council shall submit annual and, when necessary, special reports to the General Assembly for its consideration.
The Members of the United Nations agree to accept and carry out the decisions of the Security Council in accordance with the present Charter.
In order to promote the establishment and maintenance of international peace and security with the least diversion for armaments of the world’s human and economic resources, the Security Council shall be responsible for formulating, with the assistance of the Military Staff Committee referred to in Article 47, plans to be submitted to the Members of the United Nations for the establishment of a system for the regulation of armaments.
Each member of the Security Council shall have one vote.Decisions of the Security Council on procedural matters shall be made by an affirmative vote of nine members. Decisions of the Security Council on all other matters shall be made by an affirmative vote of nine members including the concurring votes of the permanent members; provided that, in decisions under Chapter VI, and under paragraph 3 of Article 52, a party to a dispute shall abstain from voting. The United Nations have 193 members’ and only 3 states or countries are not members of the organization (Kosovo, which did not gain membership, Taiwan which was replaced by China, and the Vatican that decided not to be a member).
The permanent members enjoy a special right called VETO, that means, they can annul the resolutions and the decisions of other non permanent members. I believe,regardless whatever argument behind this privilege is, it has been a hindrance to a better function of the organization.
