Riccardo Vecellio Segate (SPAIS, FSSL, University of Bristol (UK)) has posted The Effect of the Constitutionalisation of the EU's Legal Framework on European Integration on SSRN. Here is the abstract:
This paper discusses the effect of the constitutionalisation of the EU’s legal framework on European integration. The first section deals with the evolution of the Treaties as a pathway towards increasing legal integration. The second section discusses the EU’s evolving constitutional doctrine. The remaining sections provide supportive evidence to back up the previously introduced arguments, drawing on a number of important issues such as division of competences and human rights, leaving an input for further research on the impact of Brexit on the matter.
