The UN Charter enshrines the right of all people to determine their own future, a principal known as self-determination. It states that The Purposes of the United Nations are:
“To develop friendly relations among nations based on respect for the principle of equal rights and self-determination of peoples, and to take other appropriate measures to strengthen universal peace.”
Self-determination is also considered a fundamental human right, with Article 21 of the Universal Declaration of Human Rights stating:
In exercising this right, the people of the Falkland Islands have decided to retain their status as an Overseas Territory of the UK.
