Abstract

This paper analyses the mutual influence and self-perpetuating cycle of legitimacy of EU legal scholars and the Court of Justice of the European Union (CJEU) in expanding and broadening the free movement rights of Union citizens and their family members. It is argued that legal scholars have played a dual role in promoting the constitutional paradigm of an ever-expanding scope of directly enforceable residence and movement rights in the EU. First, by presenting the expansion of free movement rights as an inevitable outcome of the EU constitutional order based on directly enforceable individual rights, scholars have played a significant role in legitimizing the jurisprudence of the Court in the face of initial resistance from the member states. Second, legal scholars have been an important source for the Court of Justice in developing its case law in this area. The Advocates General in their opinions have drawn on an expanding field of scholarship presenting the expansion of free movement rights as an inherent feature of the EU as a constitutional legal order. Spurred by the objective of turning the EU into more than an internal market, the opinions of the Advocates General have mostly been followed by the Court. Legal scholars have thus served not only as a legitimizing force, but also as a source of inspiration for the perceived constitutionalization of free movement rights in the EU.

40 See Case C-456/02 Trojani [2004] ECR I-7573. The Court has, however, set certain restrictions on the right of access to social benefits. For instance, in Bidar (Case C-209/03), it argued against the Advocate General, holding that a certain degree of integration, possibly appropriate residence requirement, can be required. Moreover, the Union citizen may not become an unreasonable burden on the welfare system of the host member state. The Court has also stressed in Vatsouras (Joined Cases C-22/08 and C-23/08) that Article 24(2) of Directive 2004/38 remains valid and that member states retain competence to evaluate whether a jobseeker is entitled to receive social assistance whilst actively seeking work and having a genuine chance of finding employment. Benefits intended to facilitate access to the labour market, such as jobseeker’s allowances, however, are not to be regarded as social assistance and must be made available.

47 Case C-60/00 Carpenter [2002] ECR I-6279. According to the Court, the content of the right to family life must be defined in line with Article 8 ECHR and the case law of the ECtHR. See also Case C-459/99 MRAX [2002] ECR I-6591; Case C-540/03 Parliament v Council [2006] ECR I-5769. Hence, in the official discourse of the Court, the right to respect for private and family life enshrined in Article 7 of the Charter of Fundamental Rights offers the same level of protection as Article 8 ECHR.47 Yet, the jurisprudence of the Court in Carpenter, Akrich, Metock and Zambrano suggests a much more inclusive approach than that pursued by the ECtHR. Union citizens’ right to family life is protected also in cases where the family relationship was established at a point of time where the residence status of the applicant was precarious.
