This book investigates the conceptual and practical application of the margin of appreciation doctrine within the framework of the European Court of Human Rights. Andrew Legg, a legal scholar, examines how the doctrine functions as a mechanism for balancing national sovereignty with the international protection of human rights. The text provides a rigorous analysis of the relationship between deference, proportionality, and the legitimacy of judicial review in supranational legal systems.

Legal scholars and practitioners frequently cite this work as a definitive analysis of the intersection between national discretion and international oversight. Experts highlight the text for its clarity in navigating the complex interplay between proportionality and judicial deference in human rights litigation.
