Unconstitutional changes of government (UCG) remain a constant challenge to democracy, governance and political stability on the African continent. These occurrences in the post-Cold War era have been characterized by the emergence of more subtle ways of accessing and maintaining power. To respond to the threat, the African Union (AU), supported by sub-regional entities, has adopted a zero-tolerance policy against UCGs. Such response includes the establishment of a sanctions regime to ensure a return to democratic and constitutional order in case of UCG in a given member state. Despite significant normative and practical gaps, the AU norm on UCG shows promise and remains a valuable tool to address anti-democratic coups on the continent. Moving forward, it is imperative to focus on improving the current legal and institutional framework against UCG to foster a more comprehensive and coordinated African-led response to these crises on the continent
