The right of peoples to self-determination is a cardinal principle in modern international law (commonly regarded as a jus cogens rule), binding, as such, on the United Nations as authoritative interpretation of the Charter’s norms. It states that peoples, based on respect for the principle of equal rights and fair equality of opportunity, have the right to freely choose their sovereignty and international political status with no interference. This principle can be traced to the Atlantic Charter, signed on 14 August 1941, by Franklin D. Roosevelt, President of the United States of America, and Winston Churchill, Prime Minister of the United Kingdom, who pledged The Eight Principal points of the Charter. It also is derived from principles espoused by United States President Woodrow Wilson in his Fourteen points following World War I, after which some new nation states were formed, or previous states were revived after the dissolution of empires. The principle does not state how the decision is to be made, nor what the outcome should be, whether it be independence, federation, protection, some form of autonomy or full assimilation. Neither does it state what the delimitation between peoples should be—nor what constitutes a people. There are conflicting definitions and legal criteria for determining which groups may legitimately claim the right to self-determination.
On 14 December 1960, the United Nations General Assembly adopted United Nations General Assembly Resolution 1514 (XV) under titled Declaration on the Granting of Independence to Colonial Countries and Peoples, which supported the granting of independence to colonial countries and peoples in providing an inevitable legal linkage between self-determination and its goal of decolonisation, it postulated a new international law-based right of freedom also in economic self-determination. Article 5 states: Immediate steps shall be taken in Trust and Non-Self-Governing Territories, or all other territories which have not yet attained independence, to transfer all powers to the peoples of those territories, without any conditions or reservations, in accordance with their freely expressed will and desire, without any distinction as to race, creed or colour, in order to enable them to enjoy complete independence and freedom.
