This chapter examines the history of case-law, legislation, and equity, with particular reference to legal change. The common law was evidenced by judicial precedent, but single decisions were not binding until the nineteenth century. It was also rooted in professional understanding, the ‘common learning’ acquired in the inns of court. It was based on ‘reason’, operating within a rigid procedural framework. Legal change could be effected by fictions, equity, and legislation, but (except during the Interregnum) there was little systematic reform before the nineteenth century. Legislation was external to the common law, but it had to be interpreted by common-law judges and so there was a symbiotic relationship between statute-law and case-law. Codification has sometimes been proposed, but with limited effect.
