This book emanates from a duo-colloquium which explored the Europeanisation of private law in the context of efforts to consolidate the consumer acquis, the Draft Common Frame of Reference, the appointment of an Expert Group on a Common Frame of Reference in the area of European contract law, the passage of the Consumer Rights Directive and the proposed Common European Sales Law. This book, with fully updated contributions, critically reflects on whether the process of Europeanisation, which has shaped private law in the EU Member States, has now reached a significant turning point in its development, a point of punctuated equilibrium. Written by a team of leading authors, the topics covered will be of concern in all European legal systems and beyond.
