This book explores the intricate and multi-dimensional conception of clarity and obscurity in the law. It presents and examines the most recent research and theories, giving practical guidance on how to avoid obscurity in legal drafting and its impact on legal interpretation. The book is aimed at a multidisciplinary audience and seeks to promote an interdisciplinary debate on clarity, law and language, calling for the moving of clarity beyond the study of plain language. The aims of the book are thus two fold. The first is to critically reach a nexus between the disciplines of law and language with respect to the debates on clarity in legal discourse. The second is to achieve an international perspective on the issue, drawing from a wide range of legal and political contexts.
