The EIO has become an integral part of EU judicial cooperation and Eurojust’s work since the transposition deadline for the directive passed in May 2017. In 2021, Eurojust dealt with 4 262 cases involving an EIO, and provided assistance to resolve issues concerning challenges with the execution of EIOs for the hearing of suspects or accused persons via videoconference, or the interception of telecommunication.

Eurojust also monitors relevant CJEU case-law developments in the field of the EIO directive and their possible impact on judicial cooperation, for example in Case C-852/19 (Gavanozov II), and C-724/19 (HP).
