Who does What? On the Allocation of Regulatory Competences in European Private Law

There is an increasing debate on the way in which the EU has developed and what it must look like in the future. This debate includes a discussion on one of the core aspects of European integration: at which level should the rules be set and who decides where the authority to do so should lie? Private law has an important role to play in this discussion. Many private law rules touch on the core of the internal market as they serve to foster trade or to offer protection to market participants, such as consumers.
