EU coordination of social security from the point of view of EU integration theory

This article comprises a study of the negotiation of the Commission's proposal for amending Regulation (EC) No 883/2004 on the coordination of social security systems and Regulation (EC) No 987/2009 in the context of EU integration theories. This analysis is used to argue that the current integration stage in the coordination of social security is a complex phenomenon which displays elements of intergovernmentalism, neo-functionalism and post-functionalism. The negotiation process highlights the disagreements between the key players which may have important consequences for the future of EU regulation in the area of coordination of social security. The article concludes that the signs of intergovernmentalism are prevalent, as evident in the attention the Commission has given to the concerns of the Member States, the negotiating position of the Council, and the vote of the European Parliament which failed to approve the proposal at the first reading. This prevalence has led to a pause in the reform of the coordination regulations and may eventually lead to compromises that will weaken the progress of integration in the future. At the same time, the article argues that the theory of post-functionalism is important in explaining the phenomenon of Brexit with regard to the UK's position in the negotiation of the Commission's proposal and its future relevance for UK and EU citizens affected by the UK's departure from the EU. The article concludes that disintegration along the lines of post-functionalism should not prevent the reintegration of the UK into the EU coordination of social security schemes, but may reinforce the prevalence of intergovernmentalism.
