UN instruments remain the primordial instruments of migration governance. In the past, UN instruments have been used in a significant portion of EU AFSJ laws to both legitimate and standard set in EU law-making in the Stockholm programme, in particular as to directives (Fahey, 2016). The EU’s legislative programme in the AFSJ has dropped off numerically in recent times. Instead, new instruments are frequently related to emergency stop-gap principles and migration related laws. How do external norms operate here? Do they ‘police’ standards? How do legal instruments regulating the external dimension of migration draw upon UN soft and hard law/ principles? What is the understanding and definition of best practice and ‘global’ standards here? What is the place of external norms in both hard and soft legal instruments? How do external norms arise for consideration?
