The UN Charter and resolutions

In 1941 Allies of World War II declared the Atlantic Charter and accepted the principle of self-determination. In January 1942 twenty-six states signed the Declaration by United Nations, which accepted those principles. The ratification of the United Nations Charter in 1945 at the end of World War II placed the right of self-determination into the framework of international law and diplomacy.

On 14 December 1960, the United Nations General Assembly adopted United Nations General Assembly Resolution 1514 (XV) subtitled " Declaration on the Granting of Independence to Colonial Countries and Peoples ", which supported the granting of independence to colonial countries and people by providing an inevitable legal linkage between self-determination and its goal of decolonisation. It postulated a new international law-based right of freedom to exercise 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 people 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.

On 15 December 1960 the United Nations General Assembly adopted United Nations General Assembly Resolution 1541 (XV), subtitled "Principles which should guide members in determining whether or nor an obligation exists to transmit the information called for under Article 73e of the United Nations Charter in Article 3", which provided that "he inadequacy of political, economic, social and educational preparedness should never serve as a pretext for delaying the right to self-determination and independence." To monitor the implementation of Resolution 1514, in 1961 the General Assembly created the Special Committee referred to popularly as the Special Committee on Decolonization to ensure decolonization complete compliance with the principles of self-determination in General Assembly Resolution 1541 (XV).

However, the charter and other resolutions did not insist on full independence as the best way of obtaining self-government, nor did they include an enforcement mechanism. Moreover, new states were recognized by the legal doctrine of uti possidetis juris, meaning that old administrative boundaries would become international boundaries upon independence if they had little relevance to linguistic, ethnic, and cultural boundaries. Nevertheless, justified by the language of self-determination, between 1946 and 1960, thirty-seven new nations in Asia, Africa, and the Middle East gained independence from colonial powers. The territoriality issue inevitably would lead to more conflicts and independence movements within many states and challenges to the assumption that territorial integrity is as important as self-determination.
