This edited volume is based on the European Law Institute's project, 'The Prevention and Resolution of Conflicts of Exercise of Jurisdiction in Criminal Law'. The ELI's project on conflicts of jurisdiction in criminal law was set up to explore options for a coherent regulatory mechanism for the prevention and settlement of conflicts of jurisdiction, which is essential for the effective functioning of a European criminal justice area built on mutual recognition. Currently, there are no binding instruments establishing a mechanism to resolve conflicts of (exercising) jurisdiction in criminal matters in the EU.
