If this question is answered in the affirmative, how could that balance of interests be achieved in concrete terms? (3) Is the answer to Question 1 affected by the legal consequences of [the Withdrawal Agreement] in that one of the mothers listed on the birth certificate issued in another Member State is a United Kingdom national whereas the other mother is a national of an EU Member State, having regard in particular to the fact that the refusal to issue a Bulgarian birth certificate for the child constitutes an obstacle to the issue of an identity document for the child by an EU Member State and, as a result, may impede the unlimited exercise of her rights as [a Union] citizen? (4) If the first question is answered in the affirmative: does EU law, in particular the principle of effectiveness, oblige the competent national authorities to derogate from the model birth certificate [which is one of the model civil status certificates] applicable [at a national level]?’ Procedure before the Court 33 In its request for a preliminary ruling, the referring court requests that the case be dealt with under the expedited procedure provided for in Article 105 of the Rules of Procedure of the Court of Justice. The referring court states in particular that the Bulgarian authorities’ refusal to issue a birth certificate to S.D.K.A., who is a Bulgarian national, makes it very difficult for that child to obtain a Bulgarian identity document and, therefore, to exercise her right to move and reside freely within the territory of the Member States, which is guaranteed in Article 21 TFEU. 34 Article 105(1) of the Rules of Procedure provides that, at the request of the referring court or, exceptionally, of his own motion, the President of the Court may decide, after hearing the JudgeRapporteur and the Advocate General, that a reference for a preliminary ruling is to be determined pursuant to an expedited procedure where the nature of the case requires that it be dealt with within a short time. 35 In the present case, on 19 October 2020, the President of the Court decided, after hearing the JudgeRapporteur and the Advocate General, to grant the request for an expedited procedure mentioned in paragraph 33 of the present judgment. The reason for that decision was that S.D.K.A., a young child, is currently without a passport but resides in a Member State of which she is not a national. In so far as the questions referred are intended to determine whether the Bulgarian authorities are required to issue a birth certificate for that child and it is apparent from the request for a preliminary ruling that such a document is necessary, according to national law, in order to obtain a Bulgarian passport, an answer from the Court within a short period of time could help to ensure that that child is able to obtain a passport more quickly (see, to that effect, order of the President of the Court of 3 July 2015, Gogova, C‑215/15, not published, EU:C:2015:466, paragraphs 12 to 14). Consideration of the questions referred 36 By its questions, which it is appropriate to examine together, the referring court asks, in essence, whether EU law obliges a Member State to issue a birth certificate, in order for an identity document to be obtained according to the legislation of that State, for a child, a national of that Member State, whose birth in another Member State is attested by a birth certificate that has been drawn up by the authorities 25/08/2022, 16:46
