Private international law and EU external relations: Think local act global, or think global act local?

In the European Union, private international law has almost exclusively been developed through the adoption of internal acts (particularly EU Regulations) in the pursuit of internal goals (principally, enhancing the efficient functioning of the internal market, and more recently and broadly the construction of an area of freedom, security and justice). This focus has and must come under challenge in light of two developments. The first is the apparent establishment of EU exclusive external competence in the field of private international law, creating the opportunity for external action by the EU. The second is the increased recognition that internal action by the EU has external effects, which should be viewed not merely as incidental but also as potentially instruments of external policy. In conjunction, these developments demand consideration of what role private international law could and should play as part of EU external relations. This article critically examines a range of possible techniques which might be adopted in relation to this new external dimension of EU private international law. These methods are not necessarily unique to private international law or the EU, and thus this article also provides a case study of the range of legal techniques which can be used by international actors to project policies externally
