This compendium showcases critical analyses of the current administration of criminal justice state Laws. Focusing on 13 out of the 29 relevant ACJLs, the aim of the compilation is to provide a comprehensive database for relevant stakeholders. The analyses adopt the Administration of Criminal Justice Act, 2015 as the baseline tool for assessing the various State laws due to its closeness to the vision of an effective and efficient system, if properly implemented. Notably, three states- Lagos, Anambra and Ekiti- enacted their respective ACJL prior to the ACJA. Utilising the ACJA as the baseline for these states still remains relevant in this context to highlight trends of uniformity or divergence.
