This collection focuses on the particular nexus of popular sovereignty and constitutional change, and the implications of the recent surge in populism for systems where constitutional change is directly decided upon by the people via referendum. It examines different conceptions of sovereignty as expressed in constitutional theory and case law, including an in-depth exploration of the manner in which the concept of popular sovereignty finds expression both in constitutional provisions on referendums and in court decisions concerning referendum processes. While comparative references are made to a number of jurisdictions, the primary focus of the collection is on the experience in Ireland, which has had a lengthy experience of referendums on constitutional change and of legal, political and cultural practices that have emerged in association with these referendums. At a time when populist pressures on constitutional change are to the fore in many countries, this detailed examination of where the Irish experience sits in a comparative context has an important contribution to make to debates in law and political science.

The Draft European Constitution was arguably both an attempt to constitutionalise the Union, re-framing that project in the language of the state, and an attempt to stretch the boundaries of constitutionalism itself, re-imagining that concept to accommodate the sui generis European Union. The (partial) failure of this project is the subject of this collection of essays. The collection brings together leading EU constitutional scholars to consider, with the benefit of hindsight, the purportedly constitutional character of the proposed Constitutional Treaty, the reasons for its rejection by voters in France and the Netherlands, the ongoing implications of this episode for the European project, and the lessons it teaches us about what constitutionalism really means.
