Many countries around the world are now using the public-private partnership (PPP) model to develop infrastructure projects. The main reasons for adopting the PPP model of procurement are to make up for budget deficits, tap into private-sector funding and expertise as well as for the public authority to concentrate on policymaking. This paper examines the legal framework for PPP in South Africa and Nigeria. The aim is to highlight the lessons that can be learned from the regulation of PPP in both jurisdictions. Comparatively, South Africa has had a better experience in PPP practice and administration. The paper recommends the implementation of some lessons learned from South Africa to improve the framework and performance of PPP arrangements in Nigeria.
