Extradition – European arrest warrant. Mere notification by a member state of intention to withdraw from the European Union did not have the consequence that, if it issued a European arrest warrant (EAW), the executing member state had to refuse to execute it or postpone its execution pending clarification of the law that would be applicable in the issuing member state after its withdrawal. The Court of Justice of the European Union further held that, absent substantial grounds to believe that the person was at risk of being deprived of rights following the withdrawal, the executing member state could not refuse to execute that EAW while the issuing member state remained a member of the EU.
