Abstract The Nigeria-Cameroun border conflict, which had claimed many lives and properties, was finally resolved on October 2002 following the ICJ ruling which ceded the disputed Bakassi Peninsula to the Republic of Cameroon. The rapidity with which President Obasanjo implemented the handover of Bakassi to Cameroon was seen in the average eye of a Nigerian as a diplomatic blunder considering the historical underpinnings of the people of Bakassi. This study was therefore aimed at a critical examination of the fundamental rights of the people of Bakassi Peninsula in the management of the Nigerian-Cameroun dispute by President Obasanjo. In doing this, the study was anchord on two research questions, thus: (1) Did Olusegun Obasanjo’s support for the ICJ ruling over the disputed Bakassi Peninsula undermine Nigeria’s national interest in the protection of her citizens and territorial integrity?; (2) Has the Nigerian government is inability to explore alternative policy options to ICJ ruling undermined the right to decide where to belong by the Bakassi people?. We used qualitative descriptive method to collect data from secondary sources. Qualitative descriptive method was equally used in analyzing our data. Thus, applying logically the core assumptions of Games theory, the study contended that Obasanjo’s acceptance of the ICJ ruling to cede away the disputed Bakassi Peninsula to Republic of Cameroon was against the national interest of Nigeria. Arising from this therefore, we recommended, among other things, that Nigerian foreign policy machinery should be henceforth situated and located in the hands of experts.
