What are the human rights obligations of Frontex and its member states at the borders of Europe? Who is responsible when the rights of people crossing those borders are breached? Those are the main questions that this book addresses while exploring the evolution of the European integrated border management (EIBM).The mode of administration of European borders has become a complex and polymorphous affair involving multiple actors working at different levels, with different competences and powers. In this context, borders are no longer lines on a map but enmeshed in a tapestry of different actors and technologies. This evolution not only puts to test the relationship between territory and public power, but it also requires a different understanding of the responsibility for the exercise of that power by a panoply of actors.This book addresses the challenges related to the implementation of the EIBM and the human rights responsibilities that it can trigger. It entwines two separate but interlaced discourses: the first being a reflection on the concept of EIBM and its human rights impact; the second being the question of the attribution of international responsibility for violations that occurred in the implementation of the EIBM.
