This insightful book, with contributions from leading international scholars, examines the European model of social justice in private law that has developed over the 20th century. The first set of articles is devoted to the relationship between corrective, commutative, procedural and social justice, more particularly the role and function of commutative justice in contrast to social justice. The second section brings together scholars who discuss the relationship between constitutional order, the values enshrined in the constitutional order and the impact of constitutional values on private law relations. The third section focuses on the impact of socio-economic developments within the EU and within selected Member States on the proprietary order of the EU, on the role and function of the emerging welfare state and the judiciary, as well as on nation state specific patterns of social justice. The final section tests the hypothesis to what extent patterns of social justice are context related and differ in between labour, consumer and competition law. The Many Concepts of Social Justice in European Private Law will prove to be of great interest to academics of law, as well as to private lawyers and European policymakers.
