In the wake of the Eurozone crisis and Brexit the European Union faces difficult questions about its future. In this debate, the law has a central role to play. But what exactly is EU law about? And why do its Member States respect the commitments they made when they signed the treaties so much more effectively than other treaty-based regimes?



The European Union is rarely out of the news and, as it deals with the consequences of the Brexit vote and struggles to emerge from the eurozone crisis, it faces difficult questions about its future. In this debate, the law has a central role to play, whether the issue be the governance of the eurozone, the internal market, 'clawing back powers from Europe' or reducing so-called 'Brussels red tape'. In this Very Short Introduction Anthony Arnull looks at the laws and legal system of the European Union, including EU courts, and discusses the range of issues that the European Union has been given the power to regulate, such as the free movement of goods and people. He considers why an organisation based on international treaties has proved capable of having far-reaching effects on both its Member States and on countries that lie beyond its borders, and discusses how its law and legal system have proved remarkably effective in ensuring that Member States respect the commitments they made when they signed the Treaties. Answering some of the key questions surrounding EU law, such as what exactly it is about, and how it has become part of the legal DNA of its Member States so much more effectively than other treaty-based regimes, Arnull considers the future for the European Union.
