The Quality of Sovereignty

It can generally be agreed that the purpose of sovereignty is to enable a government to protect the best interests of its citizens. To what extent did UK membership of the EU preclude this? In the context of the EU, the discussion on sovereignty tends to focus on quantity – the greater the scope of action of the EU and its institutions, the lower the sovereignty of the member states. From this perspective, sovereignty is a zero-sum affair – less means less. However, sovereignty can also be assessed from a qualitative perspective, with a focus on its quality, or character, rather than its scope.

An Interactive Relationship

In reflections on fifty years of membership, the employment of women is often identified as a tangible example of how membership changed Ireland. Concretely, in the years immediately following accession, the state was required to enact legislation on equal pay and equal treatment for women and men in employment. This narrative tends to place emphasis on EU law as a cause of law reform in Ireland. 50 years on, both Irish and EU equality law have expanded significantly.

Constitutional Identity, Ireland and the EU

Costello v. Government of Ireland and others is one of the most significant recent Irish Supreme Court rulings concerning EU law. The case involved a member of parliament seeking to restrain the Irish government from ratifying the 2014 EU-Canada Comprehensive Economic and Trade Agreement (CETA) on grounds of alleged unconstitutionality. Costello’s most long-lasting impact is likely to be its introduction of the concept of constitutional identity into Irish constitutional jurisprudence.

Post-Brexit Sovereignty

In thinking about sovereignty within the United Kingdom, it is helpful to separate out two ways in which sovereignty has historically been identified in both the United Kingdom and elsewhere. Sovereignty is, first, a power over others, most notably absolute and final authority over a territory. If this allows those holding it to achieve considerable things, it also generates apprehension as it allows them to do many things to others. Sovereignty is, secondly, a constitutive power.

Integration and Disintegration

In our analysis below, we examine the convergent and divergent paths of Ireland and the UK on the theme of integration and disintegration in three stages. The first considers the constitutional context and framework within which each of the two countries chose to embark on the path of European integration by acceding to the EEC in the early 1970s. The second examines several key policy choices made by the two states along a continuum between integration and disintegration, as part of a more differentiated, post-Maastricht EU. The final stage examines the implications of Brexit for the UK and Ireland following Britain’s departure from the EU.

50 Years On

In 1973 and on the third attempt, Ireland and the United Kingdom (UK) with Denmark acceded to the European Communities, while Norway opted not to join following a referendum. For Ireland and the UK, the half-century since has brought about remarkable social, economic, demographic, political, and legal changes in both states leading to the UK leaving the EU in 2020 and Ireland remaining a Member State. Given the shared anniversary and divergent responses to EU membership in the context of strong (if complex) ties between the two states and a shared common law tradition, a reflection on the 50th anniversary of their accession to what is now the European Union (EU) is timely.
