April’s Guest Editorial is by Professor Horatia Muir-Watt: Reshaping Private International Law in a Changing World.
Horatia Muir Watt is Professor of Private International and Comparative Law at the University of Paris I (Panthéon-Sorbonne). She prepared her doctorate in private international law (University of Paris 2, 1985) and was admitted to the agrégation in 1986. She was then appointed to the University of Tours, then the University of Paris XI, before joining Paris I in 1996. She is Deputy Director of the Comparative Law Center of Paris (UMR de Droit comparé, Paris I-CNRS) and Editor in Chief of the Revue critique de droit international privé, the leading law review on private international law in France. She directs the Masters program in Anglo-American Business Law and co-directs the Masters program in Global Business law (Paris I/Institute of Political Science). She has been regular visitor to the University of Texas in Austin, where she has taught the Conflict of Laws. She lectured in July 2004 at the Hague Academy of International Law. Her course on “Aspects économiques de droit international privé” has been published in vol. 307 of the Recueil des Cours. She has published two other books: Common law et tradition civiliste, PUF 2006, with Duncan Fairgrieve (a pocket comparative study) and Droit international privé, PUF, 2007, with Dominique Bureau (a treatise in 2 volumes). She publishes numerous law review articles, contributions to Mélanges and legal encyclopedieas, case-notes and book reviews, introductions and prefaces (including, recently, The making of European Private Law: Regulatory Strategies and Governance, with Fabrizio Cafaggi, to be published, Sellier, 2008).

Reshaping Private International Law in a Changing World
The past few decades have witnessed profound changes in the world order – changes affecting the nature of sovereignty or the significance of territory – which require measuring the methodological impact of political and technological transformations on traditional ways of thinking about allocation of prescriptive and adjudicatory authority as between states. Myriads of issues arise in this respect within the new global environment, such as the extraterritorial reach of regulatory law, the decline of the private/public divide in the international field, the renewed foundations of adjudicatory jurisdiction (particularly in cyberspace), the implications of individual and collective access to justice in the international sphere, the impact of fundamental rights on choice of law, the ability of parties to cross regulatory frontiers and the subsequent transformation of the relationship between law and market. Indeed, one of the most important issues raised by globalization from a private international law perspective is the extent to which private economic actors are now achieving “lift-off” from the sway of territorial legal systems. To some extent, traditional rules on jurisdiction, choice of law and recognition/enforcement of judgments and arbitral awards have favored the undermining of law’s (geographical) empire, which is already threatened by the increasing transparency of national barriers to cross-border trade and investment. Party mobility through choice of law and forum induces a worldwide supply and demand for legal products. When such a market is unregulated, the consequences of such legislative competition may be disastrous.
An excellent illustration of the way in which rules on choice of law and forum, combined with a liberal regime relating to enforcement of foreign judgments, allow private confiscation of the governing law can be found in the circumstances which gave rise to the notorious Lloyd’s litigation. Here, securities offerings accompanied by inadequate disclosure on the American market managed to slip through the net of the federal Securities Acts. This example shows how “barrier-crossing” - escaping the sway of mandatory provisions by opting out of a legal system, and de facto redefining jurisdictional boundaries to suit oneself - through the mobility conferred by unfettered choice of forum alters the status of lois de police or internationally mandatory laws, which become merely “semi-mandatory” before the chosen foreign forum. Other well-known examples can be found in the field of tort, where the use of forum non conveniens to prevent access by the victims of accidents linked to delocalized industrial activities, to justice in the country of the (parent) corporate defendant, seals the downward spiral in which developing counties are trapped when economically dependant upon versatile foreign capital; lowering the cost of security, environmental protection, or social legislation will attract investment, but will maintain any liability incurred within the limits designed by the low standards of the lex loci delicti as applied by local courts. Here, rules of jurisdiction and choice of law contribute to the “global tragedy of the commons”, where in the absence of a central regulator or universally accepted standards of conduct, nothing prevents a state from abetting the exportation by its private sector of industrial costs (pollution, economies on social protection, etc) in the direction of the global community.
Insofar that it is felt desirable to ensure the “touch-down” of economic actors in this context, private international methodology may require considerable reshaping, so as to harness it to the new need for strong yet adjusted regulation of the consequences of private mobility and the inter-jurisdictional competition which it inevitably generates. Approaches developed in a world where the prescriptive authority of State was coextensive with territory are clearly no longer adapted to this function; this is particularly true of the methods inspired by the private interest paradigm on which continental Europe doctrine thrived throughout the second half of the twentieth century and is loath even today to abandon. The message of this editorial is to the effect that private international law should adjust to the stakes involved in real world conflicts of laws, which do not, or do no longer, implicate purely private interests playing out on a closed field, but involve strong state policies or substantive values perceived as fundamental by the global community; in turn, it is mistaken and indeed harmful to continue to represent the rules designed to respond to these conflicts as being “neutral”, since this leads to underestimate the needs generated by the novel ways in which national laws inter-relate in a global setting and prevents private international law from being fully invested with an appropriate regulatory function. Just three examples (among many more) will serve to draw attention to the tectonic upheavals currently occurring and to the pressing need to devote further thought to the reshaping of traditional methods and approaches.
1. Choice of law and economic due process.
Within the European Union, the appearance of a market for law is not of course a mere and perverse side-effect of other policies geared to enhancing party autonomy. Carefully designed regulatory competition in the field of goods and services has been shown to - deliberately - overturn the very concept of “monopolistic states”, even in the field of public law and services. Indeed, inter-jurisdictional mobility of firms, products and services is once again the means by which law is made to appear as offering on a competitive market, designed in turn to stimulate legislative reactivity and creativity. As illustrated in the global context, one of the market failures to be feared in the context of unregulated competition is the exporting of costs or externalities linked to legislative choices of which the consequences may affect other communities. However, in an integrated legal system, these risks are restricted by the existence of a central regulator, armed with tools such as approximation of substantive rules, or, where diversity is deemed to be desirable, constitutional instruments designed to discipline the various States in their mutual dealings. Here, as recent conflicts of laws implicating both economic freedoms and workers’ rights have shown, the Court of justice is invested with an important balancing function which clearly overflows into the political sphere.
This is where uniform choice of law rules come in, as tools of governance designed to fulfill the requirements of economic due process on a Community level. Economic due process, which is now thought to explain the requirements of the Commerce Clause in the US federal Constitution, ensures that a given community does not impose costs on out of state interests which were not represented in its decision-making process. Thus, for instance, the cost of a law providing for lax standards of environmental protection should not be exported towards a neighbouring state with different priorities: in cases of cross-border pollution, environmental damage caused in the the latter state by firms legally using low standards of protection on the other side of the frontier must be internalized by application of the more protective rule. Posting workers employed under lax labor standards to a host state with higher social protection in order to benefit from the competitive advantage of low cost labor requires application of local law for the duration of the posting in order to avoid unhealthy distorsions of competiton between firms. To a large extent, recent choice of law provisions have integrated this change.
