The statutory formulation of the rules of evidential admissibility in African jurisdictions can be characterized into two, positive and negative, broad categories. This article uses the Sowetan trope of a pair of conjoined twins, popularly known as Mpho le Mphonyana in South Africa, to analyse these two formulations with a view of exposing eight doctrinal, institutional and theoretical fallacies associated with these (English) common law colonial inheritances in Africa. The continued, and popular, focus on the Euro-American world by African Evidence scholars, notwithstanding the prevalence of these kinds of fallacies, raises serious questions not only about the scholarly and institutional future of African jurisdictions, but also about what precisely Africans think of themselves in a world that renders them largely invisible for scholarly purposes.
