In that context, the Verwaltungsgerichtshof Baden-Württemberg decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling: ‘1. On Articles 2, 3 and 7 of [Directive 2004/38]: (a) Does “family member” include, in particular in the light of Articles 7 and 24 of the [Charter of Fundamental Rights (“the Charter”)] and Article 8 of the [European Convention for the Protection of Human Rights and Fundamental Freedoms, signed in Rome on 4 November 1950,“the ECHR”)], on an extended interpretation of Article 2(2)(d) of Directive 2004/38, a parent who is a third-country national, has parental responsibility for a child who is a Union citizen entitled to freedom of movement, and is not maintained by that child? (b) If so, does Directive 2004/38 apply to that parent, in particular in the light of Articles 7 and 24 of the Charter and Article 8 of the ECHR, on an extended interpretation of Article 3(1) of the directive, even where there is no “accompanying” or “joining” with respect to the Member State of origin of the child who is a Union citizen and has moved away? (c) If so, does it follow that that parent, in particular in the light of Articles 7 and 24 of the Charter and Article 8 of the ECHR, has a right of residence for more than three months in the Member State of origin of the child who is a Union citizen, on an extended interpretation of Article 7(2) of Directive 2004/38, at least as long as parental responsibility subsists and is actually exercised? 2. On Article 6(1) TEU in conjunction with the Charter: (a) (i) Is the Charter applicable pursuant to the second alternative of the first sentence of Article 51(1) of the Charter simply where the subject‑matter of the dispute depends on a national law (or part of a law) which inter alia – but not only – transposed directives? (ii) If not, is the Charter applicable pursuant to the second alternative of the first sentence of Article 51(1) of the Charter simply because the claimant is possibly entitled to a right of residence under Union law and could accordingly, under the first sentence of Paragraph 5(2) of the FreizügG/EU, claim a residence card for a family member of a Union citizen which has its legal basis in the first sentence of Article 10(1) of [Directive 2004/38]? (iii) If not, is the Charter applicable pursuant to the second alternative of the first sentence of Article 51(1) of the Charter, in accordance with the case‑law deriving from Case C-260/89 ERT [1991] ECR I-2925, paragraphs 41 to 45, where a Member State restricts the right of residence of the father who is a third-country national with parental responsibility for a Union citizen who is a minor and resides predominantly with her mother in another Member State of the Union because of the mother’s employment? (b) (i) If the Charter is applicable, can a right of residence under European Union law for the father who is a third-country national be derived directly from Article 24(3) of the Charter, at least as long as he has and actually exercises parental responsibility for his child who is a Union citizen, even if the child resides predominantly in another Member State of the Union? (ii) If not, does it follow from the freedom of movement of the child who is a Union citizen under Article 45(1) of the Charter, possibly in conjunction with Article 24(3) of the Charter, that the father who is a third-country national has a right of residence under European Union law, at least as long as he has and actually exercises parental responsibility for his child who is a Union citizen, so that in particular the freedom of movement of the child who is a Union citizen is not deprived of all practical effect? 3. On Article 6(3) TEU in conjunction with the general principles of European Union law: (a) Can the “unwritten” fundamental rights of the European Union developed in the Court’s case‑law from Case 29/69 Stauder [1969] ECR 419, paragraph 7, up to, for example, Case C-144/04 Mangold [2005] ECR I-9981, paragraph 75, be applied in full even if the Charter is not applicable in the specific case; in other words, do the fundamental rights which continue to apply as general principles of Union law under Article 6(3) TEU stand autonomously and independently alongside the new fundamental rights laid down in the Charter in accordance with Article 6(1) TEU? (b) If so, can a right of residence under European Union law for the purpose of the effective exercise of parental responsibility be inferred from the general principles of Union law, in particular in the light of the right to respect for family life under Article 8 of the ECHR, for a father, who is a third-country national, of a Union citizen who is a minor and resides predominantly in another EU Member State with her mother on account of the latter’s occupation? 4. On Article 21(1) TFEU in conjunction with Article 8 of the ECHR: If Article 6(1) or (3) TEU does not lead to a right of residence under European Union law for the claimant, can, in accordance with Case C-200/02 Zhu and Chen [2004] ECR I-9925, paragraphs 45 to 47, a right of residence under European Union law for the purpose of the effective exercise of parental responsibility be inferred, under Article 21(1) TFEU, possibly in the light of Article 8 of the ECHR, from the freedom of movement enjoyed by a Union citizen who is a minor and resides predominantly in another EU Member State with her mother on account of the latter’s occupation, for the father, who is a third-country national, in the Member State of origin of the child who is a Union citizen? 5. On Article 10 of [Directive 2004/38]: If a right of residence under European Union law is taken to exist, is a parent who is a third-country national in the claimant’s situation entitled to the issue of a “residence card for a family member of a Union citizen”, possibly in accordance with the first sentence of Article 10(1) of the directive?’
