This book investigates the fundamental mechanisms of constitutional systems, specifically focusing on how they function to protect individual liberty and prevent the rise of tyranny. Drawing on his extensive experience as a judge at the European Court of Human Rights and his personal history living under communist rule, András Sajó provides a rigorous analysis of the structural requirements for a stable, democratic government. He argues that constitutionalism is not merely a set of laws but a necessary framework for taming political power and ensuring the rule of law.

Legal scholars and political scientists frequently cite this work as a sophisticated, accessible introduction to the complexities of constitutional design. Experts highlight Sajó’s unique perspective as a former Ecthr judge, noting that his practical experience adds significant weight to his theoretical analysis of institutional safeguards.
