This second edition of Laws and Policies: Processes and Procedures for Open Government Partnership (OGP) Implementation in Nigeria offers a deep dive into the legal frameworks and institutional mechanisms shaping Nigeria’s anti-corruption and transparency agenda under the OGP platform. Produced by Centre LSD with support from the MacArthur Foundation, the book evaluates progress made in implementing OGP Commitment 13, focused on strengthening anti-corruption legislation and institutional reform. Drawing from both government and civil society perspectives, the publication critically examines the status of key anti-corruption bills in the National Assembly, including the Proceeds of Crime Bill, Whistle Blowers Protection Bill, and Money Laundering (Prevention and Prohibition) Bill. It highlights both the achievements and the legislative stagnation that have defined Nigeria’s efforts to build a robust transparency regime. The report presents comparative insights, legislative updates, policy milestones, and actionable recommendations to strengthen legal foundations for open governance. It also outlines barriers such as lack of synergy between executive and legislative arms, insufficient political will, and the challenges of institutional overlap. This guide is an essential tool for legislators, policy advocates, civil society actors, and development partners seeking to enhance Nigeria’s commitment to transparency, citizen engagement, and accountability under the OGP framework.
