This collection presents a comparative assessment of issues impacting disclosure of criminal evidence in a range of international jurisdictions. The book introduces the major features driving disclosure practice in a mixture of common and civil law countries from across the world, including the global north and south and drawn from an extensive range of collaborators. This wide breadth of perspectives provides a comprehensive overview of how disclosure functions. Each chapter is underpinned by three core pillars, which are addressed throughout each chapter. The first explains disclosure law and its core principles in the given jurisdiction. The second provides an analysis of the key issues and challenges faced within this jurisdiction. The final pillar focuses on potential reform and the identification of best practice. The book will be a valuable resource for academics, researchers and policy-makers working in the areas of criminal procedure and justice.
