American methods of policy implementation and dispute resolution are more adversarial and legalistic when compared with the systems of other economically advanced countries. Americans more often rely on legal threats and lawsuits. American laws are generally more complicated and prescriptive, adjudication more costly, and penalties more severe. In a thoughtful and cogently argued book, Robert Kagan examines the origins and consequences of this system of "adversarial legalism."

Kagan describes the roots of adversarial legalism and the deep connections it has with American political institutions and values. He investigates its social costs as well as the extent to which lawyers perpetuate it. Ranging widely across many legal fields, including criminal law, environmental regulations, tort law, and social insurance programs, he provides comparisons with the legal and regulatory systems of western Europe, Canada, and Japan that point to possible alternatives to the American methods.

Kagan notes that while adversarial legalism has many virtues, its costs and unpredictability often alienate citizens from the law and frustrate the quest for justice. This insightful study deepens our understanding of law and its relationship to politics in America and raises valuable questions about the future of the American legal system.

In the first edition of this groundbreaking book, Robert Kagan explained why America is much more adversarial—likely to rely on legal threats and lawsuits—than other economically advanced countries, with more prescriptive laws, more costly adjudications, and more severe penalties. This updated edition also addresses the rise of the conservative legal movement and anti-statism in the Republican party, which have put in sharp relief the virtues of adversarial legalism in its ability to empower citizens, lawyers, and judges to mount challenges to the arbitrary or unlawful exercise of government authority.

“This is a wonderful piece of work, richly detailed and beautifully written. It is the best, sanest, and most comprehensive evaluation and critique of the American way of law that I have seen. Every serious scholar concerned with justice and efficiency, and every policymaker who is serious about improving the American legal order, should read this trenchant and exciting book.”
—Lawrence Friedman, Stanford University

“A tour de force. It is an elegantly written, consistently insightful analysis and critique of the American emphasis on litigation and punitive sanctions in the policy and administrative process.”
