This chapter analyses rule of law promotion and reform in post-conflict Liberia, a key priority for the Liberian government, the United Nations (UN) peacebuilding operation, and international and domestic non-governmental organizations (NGOs). Given the country’s history of poor governance and endemic corruption, this programming is extremely challenging. The judicial system is completely dysfunctional and out of date, with limited infrastructure and human capacity. Despite this difficult context, rule of law reform has resulted in some important achievements since the end of the conflict, but important challenges still remain. We first briefly outline the conflict and background of both the statutory and customary legal systems. We then discuss the key actors, their priorities and goals, and specific rule of law programmes. Finally, we consider the successes and challenges so far, and conclude with four justice gaps to address.
