Abstract : The failure of the policies engaged by the Central African States Custom Union authorities has obliged the states members to rectify the common view they had vis-à-vis the economic integration process. This failure has convinced them to imagine new ways and means to guaranty the success of the integration of their economies to the international market regarded the present financial and trade's globalisation context. For the construction of this ambitious common market based on a new organization, the members states of the Central African's Economic and Monetary Community (CAEMC) have founded their objectives on new legal rules – include material and institutional ones – which will enable them to create a new environment for the growth of their economies. Materials rules, precisely principally those organizing a free movement of goods, persons, services and capitals from a member's state to others have been consecrates by the Organization. Simultaneously, the economic actors had to be assured, and their investments being legally secured. On that way, they have decided to adopt common laws which will for the future regulate clear and loyal competition among enterprises based and intervening on the common market area. At the same time, the recent creation of a Common Court of Justice by the new institution would certainly contribute to sustain this new sub-regional ambitions and the emergence of an important market in the Central African states.
