Julia Black's book is the first authoritative study of rulemaking in one of the most important areas of economic life: financial services. She draws on theoretical and empirical studies in jurisprudence, linguistics, economics, politics, and sociology in order to understand and evaluate the formation and uses of rules in financial services regulation.

In this book legal experts analyse the origins and modern growth of judicial review and analyse how the law may develop in the future.

This third edition brings the reader fully up to date with developments in consumer law.
