To help states parties circumvent domestic prohibitions on, inter alia, the extradition of nationals, the ICC Statute formally distinguishes ‘surrender’ of individuals to the Court from interstate ‘extradition’. The European Arrest Warrant contains a similar solution. As (successful) constitutional challenges by nationals to be surrendered under a European arrest warrant indicate, such a (semantic) distinction may not suffice. Despite considerable differences between surrender within the EU and to the ICC, these cases offer useful guidance to domestic legislatures occupied with implementing obligations arising under the ICC Statute so that they can ensure that ICC requests concerning the surrender of nationals can be honoured.
