ABSTRACT
In this concluding chapter, I will explore some of the key issues for legal systems engaged in the practical challenges of promoting effective criminal justice cooperation across borders. Recent decades have witnessed the development of new administrative and legal solutions aimed at overcoming, or at least mitigating, obstacles to cross-border cooperation between policing agencies and judicial authorities at the local, regional and global level. Criminal justice cooperation is inherently a multilevel governance phenomenon occurring at many different levels and between many institutions (local, regional, national, supranational and international). Obstacles to collaboration take many forms but, in essence, fundamentally relate to the contestation and negotiation around the issue of jurisdiction. As we shall explore here, how jurisdiction is conceived and negotiated both legally, politically and bureaucratically determines the effectiveness of cross-border cooperation.
