"Article 1 (2) establishes that one of the main purposes of the United Nations, and thus the Security Council, is to develop friendly international relations based on respect for the “principle of equal rights and self-determination of peoples”. The case studies in this section cover instances where the Security Council has discussed situations with a bearing on the principle of self-determination and the right of peoples to decide their own government, which may relate to the questions of independence, autonomy, referenda, elections, and the legitimacy of governments."
