This chapter first considers the process by which Acts of Parliament come into being. It then turns to delegated legislation—that is, law that is made by other bodies under Parliament’s authority. Next, it discusses the impact of the European Convention on Human Rights and the Human Rights Act 1998. Finally it looks at EU legislation, which became increasingly significant during the time that the UK was a member of the EU. It explains the various institutions of the EU and role they had in the law-making process; the different types of EU legislation; and the circumstances in which individuals could use them in domestic courts.
