Sharing Sovereignty in the EUs Area of Freedom Security and Justice - Stefan Jagdhuber Kartoniert (TB)

European integration has turned the EU neither into a state in which authority is fully centralized in Brussels nor is the EU a classic international organization in which member states remain fully sovereign. Instead European integration is patchy. For some policies decision-making authority still rests with the member states whereas for others policy-making authority was transferred to the EU. Why does the EU's authority vary across policies?Taking policies belonging to the EU's Area of Freedom Security and Justice as a sample Stefan Jagdhuber theorizes and empirically analyzes why integration proceeded on illegal immigration policy and judicial cooperation on civil law matters whereas it stagnated for legal immigration policy and judicial cooperation on criminal law matters.The findings show that uneven integration trajectories in the EU are likely when policy interdependence supranational activism and domestic constraints differ across policies.European integration has turned the EU neither into a state in which authority is fully centralized in Brussels nor is the EU a classic international organization in which member states remain fully sovereign.
