This chapter comprises 'the regional' AU-based system, the 'subregional' system and even national laws with its case law. It focuses on its role in the realisation of right to development (RTD) in Africa. The chapter explores the substantive provisions of the RTD in the African human rights architecture with special attention to African treaties. It examines the reception of the RTD at the sub-regional level or in sub-regional treaties. The chapter discusses how article 22 of the African Charter on Human and Peoples' Rights (ACHPR) is received at the country level. It also examines the duty bearer's obligations while focusing on the RTD in selected national laws, namely: Cameroon, Uganda, Malawi, Ethiopia and South Africa. The chapter finds that at the regional level, the main African treaties which are the African Charter, the African Women's Protocol and the African Children's Charter offer a normative protection of the RTD. The Regional Economic Communities objectives revolve around insuring development on the continent.
