Formalist private lawyers, with their view of law as an autonomous sphere and their emphasis upon allocative rules, tend to approach the issue of the harmonisation of private law in Europe with the following question: are the substantive rights and remedies of private individual actors sufficiently similar within each of the Member States to allow for the unification of autonomous private legal systems. Here the issue is essentially one of terminology. While sceptical voices maintain that formal private law is also a more complex matter of interrelated procedures and practices, many formalists conclude that whilst the terms of rights and remedies may differ slightly throughout Europe, there is sufficient substantive convergence to allow for harmonisation. However, lawyers of a sociological persuasion who see private law as being contingent upon society ? a process reflexively and recursively facilitating economic activities and responding to social change ? consider harmonisation to be dependent upon the harmonisation of market practices themselves. This paper, one of the most subtle of sociological contributions, tackles this issue with an innovative eye to the increasing blurring of the distinction between public and private concerns. The voice of Europe is the voice of a political collective and theoretically, under the once sacrosanct paradigm of the public/private divide, should not be heard within the ‘individualistic’ sphere of private law. However, just as national private law judges are generally responding to social concerns and are seeking to integrate collective voices within a once ‘atomised’ realm, so too are they taking note of the political voice of Europe: attempting to respond to the desire for integration and harmonisation within their jurisprudence.
