11) Recitals 5, 6 and 31 of Directive 2004/38 are worded as follows:

‘(5) The right of all Union citizens to move and reside freely within the territory of the Member States should, if it is to be exercised under objective conditions of freedom and dignity, be also granted to their family members, irrespective of nationality. ...

(6) In order to maintain the unity of the family in a broader sense and without prejudice to the prohibition of discrimination on grounds of nationality, the situation of those persons who are not included in the definition of family members under this Directive, and who therefore do not enjoy an automatic right of entry and residence in the host Member State, should be examined by the host Member State on the basis of its own national legislation, in order to decide whether entry and residence could be granted to such persons, taking into consideration their relationship with the Union citizen or any other circumstances, such as their financial or physical dependence on the Union citizen.

...

(31) This Directive respects the fundamental rights and freedoms and observes the principles recognised in particular by the Charter of Fundamental Rights of the European Union ...’

...

64) However, that discretion must, having regard to recital 31 of Directive 2004/38, be exercised in the light of and in line with the provisions of the Charter of Fundamental Rights of the European Union (‘the Charter’) (see, by analogy, judgment of 6 December 2012, O and Others, C‑356/11 and C‑357/11, EU:C:2012:776, paragraphs 79 and 80 and the case-law cited).

65) In that regard, Article 7 of the Charter recognises the right to respect for private and family life. As is apparent from the Explanations relating to the Charter of Fundamental Rights (OJ 2007 C 303, p. 17), in accordance with Article 52(3) of the Charter, the rights guaranteed by Article 7 thereof have the same meaning and the same scope as those guaranteed by Article 8 of the European Convention for the Protection of Human Rights and Fundamental Freedoms, signed in Rome on 4 November 1950 (see, to that effect, judgments of 5 October 2010, McB., C‑400/10 PPU, EU:C:2010:582, paragraph 53, and of 5 June 2018, Coman and Others, C‑673/16, EU:C:2018:385, paragraph 49).

...

67) Article 7 of the Charter must, moreover, be read in conjunction with the obligation to take into consideration the best interests of the child, which are recognised in Article 24(2) thereof (see, to that effect, judgments of 27 June 2006, Parliament v Council, C‑540/03, EU:C:2006:429, paragraph 58; of 23 December 2009, Detiček, C‑403/09 PPU, EU:C:2009:810, paragraph 54; and of 10 May 2017, Chavez-Vilchez and Others, C‑133/15, EU:C:2017:354, paragraph 70).

...

71) In the event that it is established, following the assessment of the elements referred to in paragraphs 69 and 70 above, that the child placed under the Algerian kafala system and its guardians, who are citizens of the Union, are called to lead a genuine family life and that that child is dependent on its guardians, the requirements relating to the fundamental right to respect for family life, combined with the obligation to take account of the best interests of the child, demand, in principle, that that child be granted a right of entry and residence as one of the other family members of the citizens of the Union for the purposes of Article 3(2)(a) of Directive 2004/38, read in the light of Article 7 and Article 24(2) of the Charter, in order to enable the child to live with its guardians in their host Member State.

...

73) In the light of all of the foregoing, the answer to the first question referred is as follows:

– the concept of a ‘direct descendant’ of a citizen of the Union referred to in Article 2(2)(c) of Directive 2004/38 must be interpreted as not including a child who has been placed in the permanent legal guardianship of a citizen of the Union under the Algerian kafala system, because that placement does not create any parent-child relationship between them;

– however, it is for the competent national authorities to facilitate the entry and residence of such a child as one of the other family members of a citizen of the Union pursuant to Article 3(2)(a) of that directive, read in the light of Article 7 and Article 24(2) of the Charter, by carrying out a balanced and reasonable assessment of all the current and relevant circumstances of the case which takes account of the various interests in play and, in particular, of the best interests of the child concerned. In the event that it is established, following that assessment, that the child and its guardian, who is a citizen of the Union, are called to lead a genuine family life and that that child is dependent on its guardian, the requirements relating to the fundamental right to respect for family life, combined with the obligation to take account of the best interests of the child, demand, in principle, that that child be granted a right of entry and residence in order to enable it to live with its guardian in his or her host Member State.

...

78) Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court, the decision on costs is a matter for that court. Costs incurred in submitting observations to the Court, other than the costs of those parties, are not recoverable.

On those grounds, the Court (Grand Chamber) hereby rules:

The concept of a ‘direct descendant’ of a citizen of the Union referred to in Article 2(2)(c) of Directive 2004/38/EC of the European Parliament and of the Council of 29 April 2004 on the right of citizens of the Union and their family members to move and reside freely within the territory of the Member States, amending Regulation (EEC) No 1612/68 and repealing Directives 64/221/EEC, 68/360/EEC, 72/194/EEC, 73/148/EEC, 75/34/EEC, 75/35/EEC, 90/364/EEC, 90/365/EEC and 93/96/EEC must be interpreted as not including a child who has been placed in the permanent legal guardianship of a citizen of the Union under the Algerian kafala system, because that placement does not create any parent-child relationship between them.

However, it is for the competent national authorities to facilitate the entry and residence of such a child as one of the other family members of a citizen of the Union pursuant to Article 3(2)(a) of that directive, read in the light of Article 7 and Article 24(2) of the Charter of Fundamental Rights of the European Union, by carrying out a balanced and reasonable assessment of all the current and relevant circumstances of the case which takes account of the various interests in play and, in particular, of the best interests of the child concerned. In the event that it is established, following that assessment, that the child and its guardian, who is a citizen of the Union, are called to lead a genuine family life and that that child is dependent on its guardian, the requirements relating to the fundamental right to respect for family life, combined with the obligation to take account of the best interests of the child, demand, in principle, that that child be granted a right of entry and residence in order to enable it to live with its guardian in his or her host Member State.
