International Co-operation
EAW
The European arrest warrant (EAW) and sibling instruments for the UK and Iceland/Norway are the criminal cooperation tools used to move people between the EU Member States, Norway/Iceland and the UK for purposes of prosecution or to execute a custodial sentence. These mechanisms are based on the principle of mutual recognition with limited grounds for non-execution.
The EAW Working Group brings together practitioners to share notable cases and national practices and develop strategic litigation before the CJEU and ECtHR. Topics include procedure and practice in national jurisdictions, protection of fundamental rights, mutual recognition of surrender/extradition refusals and securing less coercive measures to surrender.
