The Court of Justice of the African Union is intended to be the "principal judicial organ of the Union." Although it has not yet been established, it is intended to take over the duties of the African Commission on Human and Peoples' Rights, as well as to act as the supreme court of the African Union, interpreting all necessary laws and treaties. The Protocol establishing the African Court on Human and Peoples' Rights entered into force in January 2004, but its merging with the Court of Justice has delayed its establishment. The Protocol establishing the Court of Justice will come into force when ratified by fifteen countries.
