EU external competences on migration: which role for mixed agreements?

---

This paper suggests a theoretical and practical analysis of the role of mixity within the development of the external dimension of EU immigration policy. For this purpose, a review on the distribution of external competences between the EU and its Member States on migration shall be undertaken, together with a presentation on the characters that mixity displays in general terms and the drawbacks inherent to its use. Particularly, this contribution will attempt to systematise the scenarios in which recourse to mixed agreements is mandatory or just optional and then apply them to migration. A special attention will be paid to the use of mixity in fields of concurrent competences, as well as to the particularities of the conclusion of association agreements in the mixed form, by reason of the special importance of these issues for EU external action on migration.
