The Triangular Relationship Between Nationality, EU Citizenship and Migration in EU Law: A Tale of Competing Competences

Abstract

Within the legal framework of the EU, the Member States have remained competent to regulate who qualifies as a national. As nationals of a Member State are simultaneously EU citizens and enjoy the right to intra-EU mobility, it is the Member States who, through their Nationality Laws, determine who is to be classed as an EU citizen and who enjoys the right to intra-EU mobility. This article explores whether Member State competence to regulate nationality matters has been affected by the introduction of EU citizenship and/or developments in intra-EU mobility rights, the contents of which are determined primarily by the EU.
