Structures of UNO

1. General Assembly:

The General Assembly is the main organizational unit of the United Nations, which carries on the processes of decision-making, policy advocacy, and representation. The diversity of the UN Member States is represented in this body, as all 193 Member States are represented in the United Nations General Assembly; hence, the body is the only one with universal representation in the UN. 

Each year, during September, every member of the UN meets in the Assembly Hall located in New York for its annual General Assembly session and the general debate, where most of the Heads of State give speeches and attend. Major issues like budgeting, membership expansion, and peacekeeping necessitate a two-thirds majority vote from the General Assembly. On other issues, there is a vote, and a simple majority determines the outcome. The General Assembly, annually, chooses a GA president for a one-year term of office.

2. Security Council:

Under the UN Charter, the Security Council is primarily responsible for maintaining international peace and security. There are 5 permanent members and 10 non-permanent members, so a total of 15 members with one vote each. The Security Council, with its expertise in international relations, emphasizes the importance of peaceful resolution for disputing parties to maintain peace and prevent aggression. It proposes various methods, such as settlement, sanctions, or the authorization of force, to maintain or restore peace on a global scale. The presidency of this organization undergoes monthly rotations.

3. Economic & Social Council:

The Economic and Social Council coordinates, reviews, and recommends policies on economic, social, and environmental issues. It implements development goals and oversees UN agencies. Its 54 members, elected by the General Assembly, serve overlapping three-year terms. It fosters reflection, debate, and innovation on sustainable development.

4. Trusteeship Council:

In 1945 the UN Charter created the Trusteeship Council, whose job it is to oversee 11 Trust Territories in preparation for their future independence. When every territory gained independence by 1994, the Council was suspended on November 1st of that year. The Council’s rules were modified on May 25, 1994, when a resolution was passed that eliminated the necessity for yearly sessions and authorized the Council, its President, or requests from the Security Council, the General Assembly, or a majority of its members to meet whenever necessary.

5. International Court of Justice:

There is a principal UN judicial body known as the International Court of Justice. Its headquarters are in The Hague, Netherlands, at the Peace Palace. Its function is to mediate conflicts of law between governments and to offer advisory views on questions of international law.

6. The Secretariat:

After the General Assembly and other important groups give orders, the Secretary-General is in charge of tens of thousands of UN workers who do them. The General Assembly elects the Secretary-General, who holds a five-year renewable term as the Organization’s Chief Administrative Officer, on the Security Council’s recommendation. Not just tied up in office tasks, the Secretary-General champions UN ideals and pushes for all folks’ rights, especially those less fortunate.

UN personnel are hired both locally and internationally to operate in peacekeeping and disaster areas. It is dangerous to promote peace in a turbulent world, and since the UN’s creation, many of its personnel have perished.

    • The UN has been deploying military personnel for service in peace operations since 1948, when the Security Council authorized the deployment of UN military observers to the Middle East to monitor the Armistice Agreement between Israel and its Arab neighbours.

      UN military personnel can be called upon to:

      Protect civilians and UN personnel;
      Monitor a disputed border;
      Monitor and observe peace processes in post-conflict areas
      Provide security across a conflict zone;
      Provide security during elections;
      Assist in-country military personnel with training and support
      Assist ex-combatants in implementing the peace agreements; they may have signed.
