Abstract: Turkey is undergoing the most substantial constitutional reform process in its history, at the same time as carrying out significant peace talks with the Kurdistan Workers’ Party. These two processes will have profound effects on the country’s future governance. Most importantly, the processes could contribute to bridging gaps in Turkey’s polarized society. As the processes take place in secret, their substantive contents are currently unknown. This article provides a critical analysis of the processes in the light of the new theory of constitutionalism, paying particular attention to the changing role of the European Union in Turkey’s reform discussions. This analysis leads to some sceptical conclusions: given the secrecy, exclusiveness and political hostility surrounding the processes, it seems that they are unlikely to achieve their potential. In addition, despite its contradictions, the weakening of European Union conditionality appears to have negatively affected the reform process.
