20. Equity: doctrines and remedies

Without assuming prior legal knowledge, books in the Directions series introduce and guide readers through key points of law and legal debate. Questions, diagrams and exercises help readers to engage fully with each subject and check their understanding as they progress. In general, the leading cases on equitable doctrines and remedies are very old. Originally developed by the old Court of Chancery in constructive competition with the common law courts, equity is now applied by the unified Supreme Court of England and Wales. This chapter looks at particular doctrines and remedies that have been developed over many centuries to help predict the way in which equity will operate in various types of case. It first discusses the distinction between different doctrines of equity before turning to the requirements for the various equitable remedies, the likelihood of success when applying for an equitable remedy and the on-going significance of equity to modern commercial life. The chapter also examines the doctrines of conversion, reconversion, satisfaction, performance and election, along with the discretionary nature of equitable remedies, injunctions, rescission, rectification, account and subrogation.
