A United Nations Security Council resolution is a UN resolution adopted by the fifteen members of the Security Council; the UN body charged with "primary responsibility for the maintenance of international peace and security". The UN Charter specifies (in Article 27) that a draft resolution on non-procedural matters is adopted if nine or more of the fifteen Council members vote for the resolution, and if it is not vetoed by any of the five permanent members. Draft resolutions on "procedural matters" can be adopted on the basis of an affirmative vote by any nine Council members.
