This chapter discusses the primary and secondary laws of the European Union (EU). Treaties are the primary law of the EU. In addition to the treaties that originally established the three European Communities, a number of other treaties have subsequently been made. These include the Treaty on European Union (the Maastricht Treaty), the Treaty of Amsterdam, the Treaty of Nice, and the Lisbon Treaty, all of which have made important amendments to the foundation treaties. Article 288 of the Treaty on the Functioning of the European Union (TFEU) confers legislative power on the Union’s institutions to make secondary legislation in accordance with the provisions of the Treaty. This secondary legislation may take different forms: regulations, directives, decisions, recommendations, and opinions. The chapter also discusses the concepts of direct applicability and direct effect, and the relationship between EU law and the English courts, and concludes by considering the likely enduring impact of EU law even after the UK has ceased to be a member state.
