For almost half a century, the Nordic countries have had a particular system of regional extradition. That system inspired and influenced the development of the European Arrest Warrant scheme at the turn of the millennium. Now, with the former Nordic system being replaced by a “Nordic Arrest Warrant”, the Nordic countries have in turn been inspired and influenced by the European Arrest Warrant scheme. In the future, it may be that the Nordic Arrest Warrant will inspire and influence further developments of the European Arrest Warrant scheme. The present article attempts an analysis of past and future interaction between developments on the Nordic level and the European Union level in this field.
