How legitimate is the struggle of the people of British Southern Cameroons? What does the future hold for such struggle? This work is an attempt to unveil facts that points to the legitimacy of the struggle of the United Nations Trust Territory for national self-determination. The issue centres on the fact that a critical review of the history demonstrates the difficulty for the people to achieve their main objective of self-determination. However, it is clear that their struggle is supported by a just and legitimate demand for basic human rights, the right to equal treatment, and the right to development. The fact also reveals that the struggle is justified and is legitimately based on the principle of jus cogens, uti possidetis juris ‘as you possess so you may possess''. The intention is to raise consciousness of the people concern to investigate and to find out if we have not failed in our responsibility as citizens of the world, if we deliberately turn away from what seems to be happening to the people of British Southern Cameroons. The Cameroun Government has the obligation to demonstrate to the people that they have a prosperous future as citizens of the Republic.
