Prof Doyle is an expert on comparative constitutional law and theory, with a particular focus on foundational questions of constitutionalism: how are constitutions made? How do constitutions relate to a particular people and territory, particularly in contested cases of secession and territorial conflict? How are constitutions changed? In 2018, he published a monograph, 'The Constitution of Ireland: A Contextual Analysis' for Hart's series on Constitutional Systems of the World. This book provides the first analysis, richly informed by comparative study, of how the Irish Constitution as a whole operates in practice. Prof Doyle is currently collaborating with Prof Rachael Walsh on a number of papers related to Ireland's experiment with citizens' assemblies and how these may inform new approaches to constitutional amendment. In 'Deliberation in Constitutional Amendment: Reappraising Ireland's Deliberative Mini-Publics' (European Constitutional Law Review, 2020), they provide the first analysis of all recommendations for constitutional amendment made by Ireland's mini-publics and explore why some gained political traction while most did not. In 'Deliberative Mini-Publics as a Response to Populist Democratic Backsliding' (Constitutional Change and Popular Sovereignty: Populism, Politics and the Law in Ireland, Routledge, 2021), they interrogate suggestions that deliberative mini-publics could help stem democratic backsliding. In 'Constitutional Amendment and Public Will Formation: Deliberative Mini-Publics as a Tool for Consensus Democracy' (International Journal of Constitutional Law, 2022), they situate deliberative mini-publics within a theory of constitutional amendment and explore their potential and problems through an analysis of Ireland's Citizens' Assembly's recommendations on abortion. Developing from this work, Prof Doyle is currently preparing a monograph on constitutional amendment. This work will theorise the distinctive democratic value of constitutional amendment and deploy that theory to reassess key debates in the field: from the unconstitutional constitutional amendment doctrine to informal constitutional amendment.
