Judicial networks have proved effective in influencing recent judicial policies enacted by both old and new EU member states. This volume seeks to improve our understanding of how networks function, the extent to which they matter in the governance of a constitutional democracy and with what consequences networks interact with hierarchical institutions that still exist within the States. The authors also examine the way the networks cross the legal and territorial borders that confine the jurisdiction of the domestic institutions, and whether they are independent of the leadership of their members.
