Equity

The Law of Equity is a unique junction where doctrinal private law, moral theory, and social perceptions of justice meet. This book explores the general principles that underlie Equity’s intervention in the Common Law, with Chapter 1 arguing that Equity should be preserved as a separate body of law which aims to align moral and legal duties in private law. Chapter 2 discusses the importance of proprietary estoppel and concludes with the argument that Equity, via the doctrine of proprietary estoppel, is redressing a significant failure in the Common Law to tackle behaviour that disregards both morality and efficiency. Chapter 3 deals with fiduciary law, highlighting the disadvantages of transforming the equitable duty of loyalty into an ordinary contractual obligation. Chapter 4 examines the clean hands doctrine, in which Equity employs the concept of integrity to construct a coherent system of reasoning about this highly-complex area. Finally, Chapter 5 discusses some findings from the analysis of fiduciary law, proprietary estoppel, and the clean hands doctrine. It highlights the family resemblance between the different doctrines we survey, and points out three areas where the distinctive nature of Equity serves the legal ideal of Accountability Correspondence, in a way that often increases the efficiency of the system.
