Book excerpt: Rights of Third-Country Nationals under EU Association Agreements highlights the significance of the rules on the free movement of persons in the association agreements between the European Union and neighbouring states, in particular Turkey. It identifies overarching themes and demonstrates the pertinence of the law and the roles of judges in enforcing and developing further the rights of individuals in association agreements across borders. The various chapters in this volume extrapolate horizontal questions of legal interpretation, constitutional formation and substantive approximation, which underlie the diverse rules in different association agreements with neighbouring countries; they support the overall conclusion that there are degrees of free movement and citizens’ rights defining the status of associated countries between membership and partnership.
