Current trends in the enlargement process of the European Union offer a virtual laboratory through which to gain insight into the mechanics of constitutional change. In particular, the Central and Eastern European countries, including Romania and Serbia, serve as great lenses through which to view the processes involved in consolidating democracy through constitutional dynamics. Even though EU accession may offer a set of incentives to these and other recent candidate countries, pro-democracy constitutional change aimed at meeting EU standards still requires a push from domestic coalitions within national political systems. By establishing a comparative framework by which to examine domestic coalitions in case studies of Romania and Serbia, this thesis offers three claims regarding constitutional change toward democracy: Firstly, that countries enacting constitutional change from within existing, consolidating democratic systems are dependent on a core group of political elites forming a coalition and embracing the cause of constitutional reform. Second, that message framing and communication on intra-governmental and public levels makes a difference in the outcome of constitutional referendums, an issue that is especially relevant in countries looking to reform constitutions to align their governance with EU standards. And finally, that institutional openness to change is indispensible to countries looking to reform constitutions in line with the Copenhagen Criteria within existing, consolidating democratic systems.
