While unification in the context of regionalism has been largely treated in integration literature, little is understood about the selective treatment of migrants and the discriminatory power of border controls, a gap that this article seeks to address through situational awareness of disunion. Regime control at the border filters undesirable elements, even when such functions may be discriminatory. While the ECOWAS Protocol A/P.1/5/79, on the free movement of people, is commendable, there are no corresponding guidelines on freedom from right abuse, violation, and discrimination at border crossings, thus stimulating new thinking. The rationale for integrating colonial inherited and partitioning of the spheres of influence is analyzed in the context of veiled disunion of assimilation versus the indirect rule agenda of the colonizers. The approach centered on historizing the social space, to explore and gain insights into what constitutes the inequitable power of borders; how they separate and produce negative freedom; and why the contradictory effects lead to an outcome of unintended discriminatory practices.
