'this book represents a very useful contribution for students of EU legal and political science studies ... the academic and political potentials of Velluti's elaborate, subtle and imaginative conceptual frame--revisiting the relationships between law, constitutionalism and new governance--are important. Her book deserves to be read carefully by the vast community of EU labour lawyers as well as by the federalism-oriented EU political scientists, both groups being generally keen to stick to hard law and the Community method. This book constitutes an opportunity for continuing the debate with them in a very challenging and constructive manner.' - Janine Goetschy, European Law Review 2011, 36(1), 155-157"Velluti's work deserves to be praised for its ability to elaborate upon and critically analyse the complexities of the EES in a broader, and extremely well developed, theoretical context. It scores highly in terms of engaging rigorously and productively with the New Governance and constitutionalism discourses and undoubtedly adds to the already well developed critical analyses of the EES and OMC produced by EU and labour law scholars. Overall a highly commendable work that leaves very few stones unturned." - Nicola Contouris, Yearbook of European Law (2011) 30(1) 465-467
