Collecting evidence in cross-border cases can be a difficult task for competent authorities in the different Member States of the European Union. Composed of different legal and judicial systems, the European Union until now had not have a unique set of rules yet enabling Member States to deal efficiently and uniformly with collection, and recognition of evidence. This seminar will present the different common investigation tools recognized at the EU level (Joint Investigation Teams, Mutual legal assistance requests, freezing orders etc.) as well as the recently adopted new legislative instrument the European Investigation Order. The analysis of those instruments and practical case studies will generate exchanges amongst participants and experts and sharing of best practices.
