How can I research the topic of UN Security Council reform?
Last Updated: May 07, 2025     Views: 43

UN Security Council reform has been discussed over many years under different agenda items in the UN General Assembly, its subsidiaries, the Security Council and its subsidiaries, as well as in informal meetings and outside of formal UN bodies. It can be difficult to research as many of the negotiations were in informal or closed meetings and documentary records can be hard to find. 

Information on the current process can be found on the UN website: Security Council Reform | General Assembly of the United Nations

From the UN Security Council Membership research guide page: 

Originally, there were 11 members of the Security Council: 5 permanent and 6 non-permanent members. In 1963, the General Assembly recommended an amendment to the Charter to increase the membership of the Security Council (the Economic and Social Council was also expanded at this time, see the ECOSOC guide):

  • A/RES/1991 (XVIII) of 17 December 1963
  • Entered into force on 31 August 1965
  • Increased membership from 11 to 15
  • Changed the number of affirmative votes required from 7 to 9
  • Set the pattern for geographic representation as follows:
    • 5 from African and Asian States
    • 1 from Eastern European States
    • 2 from Latin American States
    • 2 from Western European and other States

Note on search strategy: In the UN Digital Library, we recommend using keywords from the full name of the UN body rather than the acronym as search terms; for example, equitable representation working group gets better results than OEWG
