Social devolution and the impact of European Union Law: A critical analysis

Abstract

This article examines the extent to which EU law impacts on the relationship between the sub-national entities of a Member State where these sub-national entities have regulatory powers in the field of social protection. More specifically, it explores whether the criteria relied on in EU law for determining the scope of the circles of solidarity in the relationship between the Member States can also be applied in the context of the relations between the sub-national entities of regionalised Member States. It appears that EU law on the free movement of persons influences these matters, more specifically the European social security coordination system that determines to which national circle of solidarity a person migrating between Member States belongs. Indeed, in its judgment in the Flemish care insurance case, the Court of Justice of the European Union (CJEU) also applied these rules to some categories of persons in a cross-border situation between different regions of a single Member State. This article critically analyses this case law specifically in terms of respect for the regionalised identity of socially devolved Member States. It concludes that this kind of respect requires that in the context of the relations between sub-national entities of a regionalised Member State, the domestic constitutional rules determining the boundaries of circles of solidarity between these entities should, in all circumstances, have preference over the EU rules applicable between Member States.
