This chapter explains the process and significance of the UK’s membership of the EU and of its subsequent departure from the EU. The chapter sets out the authorities underpinning the supremacy of EU law, accepted and established prior to the UK’s accession. It then explores cases—from the early 1970s to the present day—which consider the ways in which EU membership has impacted on Parliament’s sovereignty. Following this, the chapter explores the legal and political landscape of the UK’s departure from the EU. It considers the Brexit process, the establishment of a stable legal system in the UK post-Brexit, looking in particular at the creation of retained EU law as provided for by the European Union (Withdrawal) Act 2018, the European Union (Withdrawal Agreement) Act 2020, and the future relationship between the UK and the UK, as established by the Trade and Cooperation Agreement.
