Conclusions
The Conclusions articulate the findings of the different chapters of this book as a consistent narrative that EU external relations not only have specific legal consequences for the power division between the Union and the Member States but also affect the Union’s constitutional structures at a deeper level. The interpretation of organizing principles changes in the context of external relations. Power shifts between the different EU institutions. Member States experience different and more stringent constraints on their ability to take unilateral action. More often than not, these changes and shifts empower the Union when it acts externally. Furthermore, the Union has established itself as an autonomous legal entity, whose law enjoys a unique effectiveness in practice. These unique features of the EU legal order are subject to particular pressure when the Union takes external actions. Loyalty obligations of the Member States and the institutions should be reconsidered in the light of this pressure, an explicit acknowledgement of the pluralist legitimation of Union action, and the purpose of the Union. Moreover, the Union has established numerous direct links with its citizens that create formal legal structures of bonding. These structures could and should serve as structures of justifiability, in which the Union directly addresses its citizens and explicates its purpose and added value, including in terms of democratic representation in external relations.
