(p. 43) 3. Domestic sources of law 

This chapter examines the various domestic sources of law in the UK, namely legislation, case law, and custom. Legislation comes in three forms: Acts of Parliament, subordinate legislation, and legal acts deriving from the European Union. This chapter describes the legislative process and discusses the tools of statutory interpretation through which legislation is interpreted by the courts. The chapter then moves on to look at case law, including a discussion of the doctrine of precedent and the distinction between the ratio decidendi and obiter dicta. Finally, the chapter concludes by looking at custom as source of law, noting the requirements in order for a custom to be given legal effect by the courts.
