International investment disputes involving African states before the International Centre for Settlement of Investment Disputes (ICSID) have generated significant critical inquiry. Yet, accounts of their contribution to the development of international investment law as a result of these dispute are limited. This article addresses this gap. It examines the contribution of some of the high-profile ICSID disputes involving African states to the development of international investment law. Notwithstanding the charges against African States in ICSID, I contend that the involvement of African States in ICSID Disputes has contributed to the development of international investment law. In particular, the jurisprudence that these ICSID case law has generated, not only affirm principles of international investment law, but more importantly, have opened new paths over the years for the development of international investment law.
