The appellant in the main proceedings and her three children, all four of whom are German nationals, have their registered domicile in Germany. The husband of the appellant in the main proceedings, who is the father of the three children, is a Brazilian national and has never had a registered domicile in Germany.

| 27 | Since 2002, the appellant in the main proceedings has worked as a development aid worker. Between 2013 and 2016, the family lived alternately in Germany and Brazil, where the husband of the appellant in main proceedings owns land and worked as a farmer. |

Since 2002, the appellant in the main proceedings has worked as a development aid worker. Between 2013 and 2016, the family lived alternately in Germany and Brazil, where the husband of the appellant in main proceedings owns land and worked as a farmer.

| 28 | On 6 September 2016, the appellant in the main proceedings entered into a contract of employment with an Austrian non-governmental organisation. Under that contract, the place of employment of the appellant in the main proceedings was Vienna (Austria) and both she and her family members were covered in relation to social security by the Wiener Gebietskrankenkasse (Local Health Insurance Fund, Vienna, Austria). After completing a preparatory course in Vienna between 6 September and 21 October 2016, the appellant in the main proceedings started an assignment in Uganda on 31 October 2016. That assignment, during which she was accompanied by her family, lasted until 15 August 2019 and was only interrupted, between 17 October 2017 and 7 February 2018, on account of the birth of the third child of the appellant in the main proceedings. During that interruption, the appellant in the main proceedings stayed in rooms made available to her at her parents’ home in Germany and received a childbirth allowance paid by the Local Health Insurance Fund, Vienna. From 15 August to 15 September 2019, that is to say the last month before her contract of employment ended, the appellant in the main proceedings was granted a reintegration period in Vienna. During that period, just like during the preparatory course she completed, the appellant in the main proceedings had a domicile in Vienna which had been made available to her by her employer subject to certain conditions, namely that the appellant in the main proceedings and her family could make use of it only during the training course and the reintegration period. While the appellant in the main proceedings was posted abroad, the accommodation in question was made available to other development aid workers. During those periods, the appellant in the main proceedings, as well as her children and her husband, were registered as having their primary residence in Austria. |

During those periods, the appellant in the main proceedings, as well as her children and her husband, were registered as having their primary residence in Austria.

| 29 | When the appellant in the main proceedings was carrying out her duties as a development aid worker, her husband, who accompanied her on her assignments abroad, took charge of the domestic tasks. Over the period in which she was on assignment, the appellant in the main proceedings spent her holidays in Germany, where she has bank accounts. |

Over the period in which she was on assignment, the appellant in the main proceedings spent her holidays in Germany, where she has bank accounts.

| 30 | Up until September 2016, the appellant in the main proceedings received a family allowance paid by the competent Germany authority for her first two children. By decision of that authority of 26 September 2016, that allowance was cancelled on the ground that the Republic of Austria was competent for family benefits, in view of the fact that the appellant in the main proceedings now worked in Austria and that her husband did not carry out any professional activity in Germany. |

| 31 | On 5 October 2016, the appellant in the main proceedings submitted an application for family allowances to the tax authority for her first two children and, on 8 January 2018, made the same application for her third child. She claimed that her family had no joint residence in Germany or Brazil, since all her family members habitually accompanied her to her places of employment during her assignments aboard. When the appellant in the main proceedings submitted those applications, her place of employment was Uganda. |

She claimed that her family had no joint residence in Germany or Brazil, since all her family members habitually accompanied her to her places of employment during her assignments aboard. When the appellant in the main proceedings submitted those applications, her place of employment was Uganda.

| 32 | The tax authority rejected the applications made by the appellant in the main proceedings on the ground that she was not entitled to Austrian family benefits because her activity as a development aid worker was carried out in a third country. She was therefore not pursuing activity as an employed person in Austria, within the meaning of Article 11(3)(a) of Regulation No 883/2004, and therefore did not fall within the scope of that regulation. In addition, the apartment occupied by the appellant in the main proceedings in Vienna does not constitute a ‘residence’ any more that it allows for a ‘stay’ there, within the meaning of Article 1(j) and (k) of the Regulation, and consequently the Republic of Austria is not the Member State of residence within the meaning of Article 11(3)(e) of the same regulation. Moreover, nor is the appellant in the main proceedings entitled to family benefits under national legislation. |

Moreover, nor is the appellant in the main proceedings entitled to family benefits under national legislation.

| 33 | The appellant in the main proceedings lodged an appeal against those decisions, arguing that the Republic of Austria is the Member State in which she pursued an activity as an employed person, within the meaning of Article 11(3)(a) of Regulation No 883/2004, since, according to her contract of employment, Vienna was her place of employment. In addition, she received her instructions from Vienna and both the preparatory course and the reintegration month also took place in that city. Moreover, she was registered in Vienna and the centre of her interests was located there. |

Moreover, she was registered in Vienna and the centre of her interests was located there.

| 34 | In those circumstances, the Bundesfinanzgericht (Federal Finance Court, Austria) decided to stay the proceedings and to refer the following questions to the Court of Justice for a preliminary ruling:





  ‘(1) | Is Article 11(3)(e) of Regulation (EC) No 883/2004 to be interpreted as covering a situation in which a female worker who is a national of a Member State in which she and her children also reside enters into an employment relationship as a development aid worker with an employer established in another Member State, and that employment relationship is subject to the compulsory insurance scheme under the legislation of the State of establishment, and she is posted by the employer to a third country not immediately after being employed but after completing a preparatory period and returning to the State of establishment for reintegration periods? |

Consideration of the questions referred

Consideration of the questions referred

The first question

The first question

| 35 | By its first question, the referring court asks, in essence, whether Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as meaning that an employed person who is a national of a Member State in which she and her children reside, who is hired under a contract of employment as a development aid worker by an employer established in another Member State, who is covered, pursuant to the legislation of that other Member State, by the compulsory social security scheme of the other Member State, who is posted to a third country not immediately after being employed but after completing a training course in the other Member State and who subsequently returns there for a reintegration period is to be regarded as pursuing an activity as an employed person in that Member State, within the meaning of that provision, or whether, if not, the situation of such a worker comes under Article 11(3)(e) of that regulation. |

By its first question, the referring court asks, in essence, whether Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as meaning that an employed person who is a national of a Member State in which she and her children reside, who is hired under a contract of employment as a development aid worker by an employer established in another Member State, who is covered, pursuant to the legislation of that other Member State, by the compulsory social security scheme of the other Member State, who is posted to a third country not immediately after being employed but after completing a training course in the other Member State and who subsequently returns there for a reintegration period is to be regarded as pursuing an activity as an employed person in that Member State, within the meaning of that provision, or whether, if not, the situation of such a worker comes under Article 11(3)(e) of that regulation.

| 36 | In order to answer that question, it should, first of all, be recalled that, according to the case-law of the Court, the mere fact that a worker carries on his activities outside the territory of the European Union is not sufficient to exclude the application of the EU rules on free movement of workers, in particular Regulation No 883/2004, as long as the employment relationship retains a sufficiently close connection with that territory (judgment of 8 May 2019, Inspecteur van de Belastingdienst, C‐631/17, EU:C:2019:381, paragraph 22 and the case-law cited). |

| 37 | A sufficiently close connection between the employment relationship in question and the territory of the European Union derives, inter alia, from the fact that an EU citizen, who is resident in a Member State, has been engaged by an undertaking established in another Member State on whose behalf he carries on his activities (judgment of 8 May 2019, Inspecteur van de Belastingdienst, C‐631/17, EU:C:2019:381, paragraph 23 and the case-law cited). |

| 38 | In the present case, and in the light of the information contained in the request for a preliminary ruling, it must be held that there is a sufficiently close connection between the employment relationship at issue in the main proceedings and the territory of the European Union, more specifically with Austria. The employer of the appellant in the main proceedings is established in Austria and it was in that Member State that she undertook a period of training before her assignment in Uganda as well as a reintegration period following that assignment. In addition, the contract of employment was concluded in accordance with Austrian law, the appellant in the main proceedings is covered by the Austrian social security scheme and she carries out her assignments in the context of the development aid provided by the Republic of Austria. Those factors are likewise relevant for the purposes of applying the principle that persons are to be subject to the legislation of a single Member State, as laid down in Article 11 of Regulation No 883/2004. |

| 39 | Next, with regard more specifically to whether a person such as the appellant in the main proceedings is to be regarded as having pursued her activity as an employed person ‘in a Member State’ (here: the Republic of Austria), within the meaning of Article 11(3)(a) of Regulation No 883/2004, or whether she is covered by Article 11(3)(e) of that regulation, it must be recalled that the latter provision is a residual rule which is intended to apply to all persons who find themselves in a situation which is not specifically governed by other provisions of the Regulation, with a view to introducing a complete system for determining the applicable legislation (see, to that effect, judgment of 8 May 2019, Inspecteur van de Belastingdienst, C‐631/17, EU:C:2019:381, paragraph 31). |

Next, with regard more specifically to whether a person such as the appellant in the main proceedings is to be regarded as having pursued her activity as an employed person ‘in a Member State’ (here: the Republic of Austria), within the meaning of Article 11(3)(a) of Regulation No 883/2004, or whether she is covered by Article 11(3)(e) of that regulation, it must be recalled that the latter provision is a residual rule which is intended to apply to all persons who find themselves in a situation which is not specifically governed by other provisions of the Regulation, with a view to introducing a complete system for determining the applicable legislation (see, to that effect, judgment of 8 May 2019, Inspecteur van de Belastingdienst, C‐631/17, EU:C:2019:381, paragraph 31).

| 40 | In view of that subsidiarity, it is necessary to examine whether the situation covered by point (a) of Article 11(3) of Regulation No 883/2004 corresponds inter alia to a situation such as that at issue in the main proceedings, it being understood, from the outset, that those envisaged in points (b) to (d) of that paragraph 3 are unconnected with such a situation. |

In view of that subsidiarity, it is necessary to examine whether the situation covered by point (a) of Article 11(3) of Regulation No 883/2004 corresponds inter alia to a situation such as that at issue in the main proceedings, it being understood, from the outset, that those envisaged in points (b) to (d) of that paragraph 3 are unconnected with such a situation.

| 41 | In that regard, in the present case, whilst it appears, prima facie, that the appellant in the main proceedings did not pursue her activity ‘in a Member State’, since she was on assignment in Uganda, the fact remains that it is apparent from the documents before the Court that, before leaving on assignment and following that assignment, the appellant in the main proceedings worked in Austria, where her employer is established, and that that employer even provided her with accommodation there. Furthermore, the appellant in the main proceedings, her children and her husband had their primary residence in Austria for the duration of the contract of employment and enjoyed social security cover there provided by the Local Health Insurance Fund, Vienna. |

In that regard, in the present case, whilst it appears, prima facie, that the appellant in the main proceedings did not pursue her activity ‘in a Member State’, since she was on assignment in Uganda, the fact remains that it is apparent from the documents before the Court that, before leaving on assignment and following that assignment, the appellant in the main proceedings worked in Austria, where her employer is established, and that that employer even provided her with accommodation there. Furthermore, the appellant in the main proceedings, her children and her husband had their primary residence in Austria for the duration of the contract of employment and enjoyed social security cover there provided by the Local Health Insurance Fund, Vienna.

| 42 | Even assuming that the appellant in the main proceedings had her residence in the territory of another Member State, as the tax authority argued before the referring court, a situation thus characterised has similarities with that at issue in the case that gave rise to the judgment of 29 June 1994, Aldewereld (C‐60/93, EU:C:1994:271), which concerned the interpretation of Regulation (EEC) No 1408/71 of the Council of 14 June 1971 on the application of social security schemes to employed persons and their families moving within the Community (OJ, English Special Edition, 1971(II), p. 416), which was repealed and replaced by Regulation No 883/2004. That case concerned an employee of an undertaking established in a Member State other than the employee’s State of residence who carried on his activities outside the territory of the European Union. In paragraph 24 of that judgment, the Court held that, in such a situation, the ‘legislation of the Member State of the worker’s residence cannot be applied since there is no factor connecting that legislation with the employment relationship, unlike the legislation of the State where the employer is established, which must therefore be applied’. |

Even assuming that the appellant in the main proceedings had her residence in the territory of another Member State, as the tax authority argued before the referring court, a situation thus characterised has similarities with that at issue in the case that gave rise to the judgment of 29 June 1994, Aldewereld (C‐60/93, EU:C:1994:271), which concerned the interpretation of Regulation (EEC) No 1408/71 of the Council of 14 June 1971 on the application of social security schemes to employed persons and their families moving within the Community (OJ, English Special Edition, 1971(II), p. 416), which was repealed and replaced by Regulation No 883/2004. That case concerned an employee of an undertaking established in a Member State other than the employee’s State of residence who carried on his activities outside the territory of the European Union. In paragraph 24 of that judgment, the Court held that, in such a situation, the ‘legislation of the Member State of the worker’s residence cannot be applied since there is no factor connecting that legislation with the employment relationship, unlike the legislation of the State where the employer is established, which must therefore be applied’.

| 43 | It follows that, notwithstanding that, on the facts, the work for which the appellant in the main proceedings was engaged by her Austrian employer was carried on outside the territory of the European Union and that she retained ties in her country of origin, namely the Federal Republic of Germany, through the accommodation made available there by her parents, the view must be taken that Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as designating the legislation of the Member State of her employer, that is to say Austrian legislation, as the only legislation to which that appellant must be subject, without there being any need to have recourse to the subsidiary rule laid down in point (e) of that paragraph 3. |

It follows that, notwithstanding that, on the facts, the work for which the appellant in the main proceedings was engaged by her Austrian employer was carried on outside the territory of the European Union and that she retained ties in her country of origin, namely the Federal Republic of Germany, through the accommodation made available there by her parents, the view must be taken that Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as designating the legislation of the Member State of her employer, that is to say Austrian legislation, as the only legislation to which that appellant must be subject, without there being any need to have recourse to the subsidiary rule laid down in point (e) of that paragraph 3.

| 44 | In those circumstances, the first question must be answered to the effect that Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as meaning that an employed person who is a national of a Member State in which she and her children reside, who is hired under a contract of employment as a development aid worker by an employer established in another Member State, who is covered, pursuant to the legislation of that other Member State, by the compulsory social security scheme of the other Member State, who is posted to a third country not immediately after being employed but after completing a training course in the other Member State and who subsequently returns there for a reintegration period is to be regarded as pursuing an activity as an employed person in that Member State, within the meaning of that provision. |

In those circumstances, the first question must be answered to the effect that Article 11(3)(a) of Regulation No 883/2004 is to be interpreted as meaning that an employed person who is a national of a Member State in which she and her children reside, who is hired under a contract of employment as a development aid worker by an employer established in another Member State, who is covered, pursuant to the legislation of that other Member State, by the compulsory social security scheme of the other Member State, who is posted to a third country not immediately after being employed but after completing a training course in the other Member State and who subsequently returns there for a reintegration period is to be regarded as pursuing an activity as an employed person in that Member State, within the meaning of that provision.

The second question

The second question

| 45 | By its second question, the referring court asks, in essence, whether the second paragraph of Article 288 TFEU is to be interpreted as precluding the adoption, by a Member State, of national legislation the scope ratione personae of which is broader than that of Regulation No 883/2004, in that it provides for nationals of the Contracting Parties to the Agreement on the European Economic Area to be treated in the same way as its own nationals. |

ratione personae

| 46 | It is apparent from the request for a preliminary ruling that the referring court considers that the second paragraph of Article 288 TFEU precludes a national provision, such as Paragraph 53(1) of the FLAG, in so far as, as is clear from paragraph 11 of the judgment of 10 October 1973, Variola (34/73, EU:C:1973:101), such a national provision is capable of concealing from those subject to it the directly applicable EU law and thus of effectively undermining the monopoly over the interpretation of EU law conferred on the Court. |

It is apparent from the request for a preliminary ruling that the referring court considers that the second paragraph of Article 288 TFEU precludes a national provision, such as Paragraph 53(1) of the FLAG, in so far as, as is clear from paragraph 11 of the judgment of 10 October 1973, Variola (34/73, EU:C:1973:101), such a national provision is capable of concealing from those subject to it the directly applicable EU law and thus of effectively undermining the monopoly over the interpretation of EU law conferred on the Court.

| 47 | In that regard, it appears appropriate to point out that, in accordance with the case-law of the Court, whereas, by virtue of their very nature and of their function in the system of sources of EU law, the provisions of regulations generally have immediate effect in the national legal systems without its being necessary for the national authorities to adopt measures of application, some of their provisions may, however, necessitate, for their implementation, the adoption of measures of application by the Member States (see, to that effect, judgment of 21 December 2011, Danske Svineproducenter, C‐316/10, EU:C:2011:863, paragraphs 39 and 40 and the case-law cited). |

| 48 | Member States may adopt rules for the application of a regulation if they do not obstruct its direct applicability and do not conceal its Community nature, and if they specify that a discretion granted to them by that regulation is being exercised, provided that they adhere to the parameters laid down in it (judgment of 21 December 2011, Danske Svineproducenter, C‐316/10, EU:C:2011:863, paragraph 41 and the case-law cited). |

Member States may adopt rules for the application of a regulation if they do not obstruct its direct applicability and do not conceal its Community nature, and if they specify that a discretion granted to them by that regulation is being exercised, provided that they adhere to the parameters laid down in it (judgment of 21 December 2011, Danske Svineproducenter, C‐316/10, EU:C:2011:863, paragraph 41 and the case-law cited).

| 49 | In the present case, and without it being necessary for the Court to rule on whether or not a provision such as Paragraph 53(1) of the FLAG is regarded as a measure of application of Regulation No 883/2004, it is sufficient to observe that, in any case, the direct applicability of that regulation has the effect of allowing the national courts to review the compliance of the national measure with the content of that regulation (see, to that effect, judgment of 27 September 1979, Eridania-Zuccherifici nazionali and Società italiana per l’industria degli zuccheri, 230/78, EU:C:1979:216, paragraph 34), and, where appropriate, to disapply that measure in order to ensure the primacy of EU law, that is to say, in the case in the main proceedings, that of Regulation No 883/2004. |

In the present case, and without it being necessary for the Court to rule on whether or not a provision such as Paragraph 53(1) of the FLAG is regarded as a measure of application of Regulation No 883/2004, it is sufficient to observe that, in any case, the direct applicability of that regulation has the effect of allowing the national courts to review the compliance of the national measure with the content of that regulation (see, to that effect, judgment of 27 September 1979, Eridania-Zuccherifici nazionali and Società italiana per l’industria degli zuccheri, 230/78, EU:C:1979:216, paragraph 34), and, where appropriate, to disapply that measure in order to ensure the primacy of EU law, that is to say, in the case in the main proceedings, that of Regulation No 883/2004.

| 50 | Therefore, EU law does not preclude the adoption of a provision such as Paragraph 53(1) of the FLAG provided, however, that that national provision is interpreted in accordance with Article 4 of Regulation No 883/2004 and the primacy of that regulation is not called into question. |

Therefore, EU law does not preclude the adoption of a provision such as Paragraph 53(1) of the FLAG provided, however, that that national provision is interpreted in accordance with Article 4 of Regulation No 883/2004 and the primacy of that regulation is not called into question.

| 51 | In the light of the foregoing, the second question must be answered to the effect that the second paragraph of Article 288 TFEU is to be interpreted as not precluding the adoption, by a Member State, of national legislation the scope ratione personae of which is broader than that of Regulation No 883/2004, in that that legislation provides that nationals of the Contracting Parties to the Agreement on the European Economic Area are to be treated in the same way as its own nationals, provided that the legislation is interpreted in accordance with that regulation and that the primacy of that regulation is not called into question. |

The fifth and sixth questions

The fifth and sixth questions

| 53 | By its fifth and sixth questions, the referring court asks, in essence, whether the obligation laid down in Article 60(3) of Regulation No 987/2009 to take a provisional decision vis-à-vis the national legislation applicable by priority is incumbent solely on the competent national institution to which the application for family benefits has been made or also on the national court seised of an action in that context and, if so, at what point in time that court must take such a decision. |

| 54 | As a preliminary point, it should be recalled that, according to settled case-law of the Court, questions concerning the interpretation of EU law submitted by a national court in the regulatory and factual context which that court determines as a matter of its own responsibility, the accuracy of which is not for the Court to verify, enjoy a presumption of relevance. The Court may refuse to give a ruling on a request for a preliminary ruling from a national court only where it is quite obvious that the interpretation of EU law sought bears no relation to the actual facts of the main action or its purpose, where the problem is hypothetical, or where the Court does not have before it the factual or legal material necessary to give a useful answer to the questions submitted to it (judgment of 16 June 2015, Gauweiler and Others, C‐62/14, EU:C:2015:400, paragraph 25 and the case-law cited). |

| 55 | In the present case, it must be observed that it is clear from the request for a preliminary ruling that, in the context of the dispute in the main proceedings, the referring court has already taken a provisional decision ordering the competent Austrian institution to forward the application for family benefits at issue in the main proceedings to its German counterpart and to open a dialogue procedure with the latter. |

In the present case, it must be observed that it is clear from the request for a preliminary ruling that, in the context of the dispute in the main proceedings, the referring court has already taken a provisional decision ordering the competent Austrian institution to forward the application for family benefits at issue in the main proceedings to its German counterpart and to open a dialogue procedure with the latter.

| 56 | That decision is quite clearly based on an application by analogy of Article 60(3) of Regulation No 987/2009, even though it is apparent, paradoxically, from the request for a preliminary ruling that that court considers, first, that it does not have jurisdiction to adopt such a provisional decision and, second, that there is no applicable provision where an action such as that at issue in the main proceedings is brought. |

| 57 | However, since the referring court has already taken that decision and the decision is capable of being fully effective, if only on a provisional basis, the fifth question is no longer relevant to the resolution of the dispute in the main proceedings and is, therefore, hypothetical. |

However, since the referring court has already taken that decision and the decision is capable of being fully effective, if only on a provisional basis, the fifth question is no longer relevant to the resolution of the dispute in the main proceedings and is, therefore, hypothetical.

| 58 | That finding is borne out by the fact that, as is clear from the answer to the first question, the Republic of Austria is, in the present case, to be regarded as being the Member State having primary competence, pursuant to Article 68(1)(a) of Regulation No 883/2004, to provide the family benefits at issue in the main proceedings, such that the Austrian authorities are not obliged to take, on the basis of Article 60(3) of Regulation No 987/2009, a provisional decision as to the national legislation applicable by priority. In those circumstances, the question of whether the referring court has to take such a ‘provisional’ decision in place of the Austrian authorities is hypothetical and must, therefore, be declared inadmissible. |

The seventh question

The seventh question

| 61 | By its seventh question, the referring court asks, in essence, whether Article 68(3)(a) of Regulation No 883/2004 and Article 60 of Regulation No 987/2009 are to be interpreted as being mutually binding on the institution of the Member State having primary competence and the institution of the Member State having secondary competence, such that the applicant for family benefits must submit only one application to one of those institutions and that it is then for those two institutions to deal with that application jointly, or whether the applicant has to make two separate applications to each of those two institutions. |
| --- | --- |

61

By its seventh question, the referring court asks, in essence, whether Article 68(3)(a) of Regulation No 883/2004 and Article 60 of Regulation No 987/2009 are to be interpreted as being mutually binding on the institution of the Member State having primary competence and the institution of the Member State having secondary competence, such that the applicant for family benefits must submit only one application to one of those institutions and that it is then for those two institutions to deal with that application jointly, or whether the applicant has to make two separate applications to each of those two institutions.

| 62 | In that regard, it must be observed that, pursuant to Article 68(3) of Regulation No 883/2004, if an application for family benefits is submitted to the competent institution of a Member State whose legislation is applicable, but not by priority right on the basis of paragraphs 1 and 2 of that article, ‘that institution shall forward the application without delay to the competent institution of the Member State whose legislation is applicable by priority, inform the person concerned and, without prejudice to the provisions of the Implementing Regulation concerning the provisional award of benefits, provide, if necessary, the differential supplement mentioned in paragraph 2’ and ‘the competent institution of the Member State whose legislation is applicable by priority shall deal with this application as though it were submitted directly to itself, and the date on which such an application was submitted to the first institution shall be considered as the date of its claim to the institution with priority’. |
| --- | --- |

62

In that regard, it must be observed that, pursuant to Article 68(3) of Regulation No 883/2004, if an application for family benefits is submitted to the competent institution of a Member State whose legislation is applicable, but not by priority right on the basis of paragraphs 1 and 2 of that article, ‘that institution shall forward the application without delay to the competent institution of the Member State whose legislation is applicable by priority, inform the person concerned and, without prejudice to the provisions of the Implementing Regulation concerning the provisional award of benefits, provide, if necessary, the differential supplement mentioned in paragraph 2’ and ‘the competent institution of the Member State whose legislation is applicable by priority shall deal with this application as though it were submitted directly to itself, and the date on which such an application was submitted to the first institution shall be considered as the date of its claim to the institution with priority’.

| 63 | The wording of Article 68(3) of Regulation No 883/2004 thus sets out in clear terms that, where an application for family benefits is submitted to the competent institution of a Member State whose legislation does not have priority, that institution must forward the application without delay to the competent institution of the Member State whose legislation is applicable by priority and inform the applicant accordingly. In such circumstances, that second institution is required to deal with the application in question as if it had been submitted to it directly on the date on which it was submitted to the first institution. |

63

The wording of Article 68(3) of Regulation No 883/2004 thus sets out in clear terms that, where an application for family benefits is submitted to the competent institution of a Member State whose legislation does not have priority, that institution must forward the application without delay to the competent institution of the Member State whose legislation is applicable by priority and inform the applicant accordingly. In such circumstances, that second institution is required to deal with the application in question as if it had been submitted to it directly on the date on which it was submitted to the first institution.

| 64 | It is equally clear from the wording of Article 60(2) and (3) of Regulation No 987/2009 that, if the institution to which an application is made in accordance with paragraph 1 of that same article concludes ‘that its legislation is applicable by priority right in accordance with Article 68(1) and (2) of [Regulation No 883/2004], it shall provide the family benefits according to the legislation it applies’ and that, if it takes the view that its legislation is applicable, but not by priority right, ‘it shall take a provisional decision, without delay, on the priority rules to be applied and shall forward the application, in accordance with Article 68(3) of [Regulation No 883/2004], to the institution of the other Member State’ and ‘shall also inform the applicant thereof’. |
| --- | --- |

64

It is equally clear from the wording of Article 60(2) and (3) of Regulation No 987/2009 that, if the institution to which an application is made in accordance with paragraph 1 of that same article concludes ‘that its legislation is applicable by priority right in accordance with Article 68(1) and (2) of [Regulation No 883/2004], it shall provide the family benefits according to the legislation it applies’ and that, if it takes the view that its legislation is applicable, but not by priority right, ‘it shall take a provisional decision, without delay, on the priority rules to be applied and shall forward the application, in accordance with Article 68(3) of [Regulation No 883/2004], to the institution of the other Member State’ and ‘shall also inform the applicant thereof’.

| 65 | It therefore follows both from Article 68(3)(a) of Regulation No 883/2004 and from Article 60(2) and (3) of Regulation No 987/2009 that the applicant must submit only one application to only one competent institution. That institution, depending on whether it regards itself as having primary or secondary competence, is obliged, in the former scenario, to provide the family benefits applied for itself and, in the latter scenario, to forward the application in question to the competent institution of the Member State which it regards as having primary competence, all with a view to ensuring that such an application for family benefits is dealt with promptly. |
| --- | --- |

65

It therefore follows both from Article 68(3)(a) of Regulation No 883/2004 and from Article 60(2) and (3) of Regulation No 987/2009 that the applicant must submit only one application to only one competent institution. That institution, depending on whether it regards itself as having primary or secondary competence, is obliged, in the former scenario, to provide the family benefits applied for itself and, in the latter scenario, to forward the application in question to the competent institution of the Member State which it regards as having primary competence, all with a view to ensuring that such an application for family benefits is dealt with promptly.

| 66 | In the light of the foregoing, the seventh question must be answered to the effect that Article 68(3)(a) of Regulation No 883/2004 and Article 60(2) and (3) of Regulation No 987/2009 are to be interpreted as being mutually binding on the institution of the Member State with primary competence and the institution of the Member State with secondary competence, such that the applicant for family benefits must submit only one application to only one of those institutions and that it is then for those two institutions to deal with that application jointly. |

The eighth and ninth questions

The eighth and ninth questions

| 67 | By its eighth and ninth questions, the referring court asks, in essence, whether Article 4(4) and Articles 45 and 208 TFEU, Article 4(3) TEU and Articles 2, 3, 7 and Title II of Regulation No 883/2004 are to be interpreted as precluding a Member State from withdrawing, as a general rule, the family benefits that it previously provided to development aid workers who take their family members to the third country to which they have been posted. |

| 68 | In order to answer that question, it should be recalled, with regard to Article 45 TFEU, first, that any Union national who, irrespective of his place of residence and his nationality, has exercised the right to freedom of movement for workers and who has been employed in a Member State other than that of residence falls within the scope of that provision (see, to that effect, judgment of 12 December 2002, de Groot, C‐385/00, EU:C:2002:750, paragraph 76 and the case-law cited). |

| 69 | Although Article 45 TFEU precludes any measure which, even if applicable without discrimination on the basis of nationality, is capable of hindering or rendering less attractive the exercise by Union nationals of the fundamental freedom of movement guaranteed by that article, that article does not confer on a worker travelling to a Member State other than his Member State of origin any entitlement, in the host Member State, to the same social welfare coverage as that which he enjoyed in his Member State of origin under the legislation of the latter State (judgment of 19 September 2019, van den Berg and Others, C‐95/18 and C‐96/18, EU:C:2019:767, paragraph 57 and the case-law cited). |

| 70 | As regards, second, Article 48 TFEU, which provides for a system for coordinating, and not harmonising, the legislation of the Member States, substantive and procedural differences between the social security schemes of individual Member States, and hence in the rights of persons who are insured persons there, are unaffected by that provision, as each Member State retains the power to determine in its legislation, in compliance with EU law, the conditions pursuant to which benefits may be granted under a social security scheme (judgment of 19 September 2019, van den Berg and Others, C‐95/18 and C‐96/18, EU:C:2019:767, paragraph 59 and the case-law cited). |

| 71 | It must be added that nor does Regulation No 883/2004 establish a common scheme of social security, but allows different national schemes to exist and its sole objective is to ensure the coordination of those schemes in order to guarantee that the right to free movement of persons can be exercised effectively. Therefore, according to the Court’s settled case-law, Member States retain the power to organise their own social security schemes (see, to that effect, judgment of 23 January 2020, Bundesagentur für Arbeit, C‐29/19, EU:C:2020:36, paragraph 39 and the case-law cited). |

| 72 | However, in exercising that power, Member States must comply with EU law and, in particular, the provisions of the FEU Treaty giving every citizen of the European Union the right to move and reside within the territory of the Member States (judgment of 23 January 2020, Bundesagentur für Arbeit, C‐29/19, EU:C:2020:36, paragraph 41 and the case-law cited). |

| 73 | In the present case, it is therefore necessary to examine whether the Republic of Austria did not infringe those provisions when it decided to withdraw the entitlement to the family benefits which it previously provided to development aid workers who take their family members to the third country to which they have been posted. |

| 74 | In that regard, it is apparent from the request for a preliminary ruling that that withdrawal, decided upon by the Austrian legislature, is general in nature and applies indiscriminately both to recipients who are nationals of that Member State and to nationals of other Member States; this is, however, for the referring court to verify. |

It does not appear therefore that that withdrawal, which took effect from 1 January 2019, gives rise to direct discrimination on the ground of nationality.

| 76 | With regard to possible indirect discrimination based on the nationality of the workers concerned, according to the Member State in which they or their family members reside, it must be observed that neither the provisions of Regulation No 883/2004, specifically Articles 7 and 67 thereof, the purpose of which is to prevent a Member State from making entitlement to and the amount of family benefits dependent on residence of the members of the worker’s family in the Member State providing the benefits (see, to that effect, judgment of 5 October 1995, Imbernon Martínez, C‐321/93, EU:C:1995:306, paragraph 21), nor Article 45 TFEU provide that the right to freedom of movement for workers applies outside the territory of the European Union. On the contrary, it is apparent from the clear wording of Article 45 TFEU that freedom of movement for workers ‘shall be secured within the Union’. |

On the contrary, it is apparent from the clear wording of Article 45 TFEU that freedom of movement for workers ‘shall be secured within the Union’.

| 77 | The withdrawal of the family benefits for development aid workers residing with their family in a third county cannot therefore constitute indirect discrimination in the territory of the European Union if – and this is a matter to be verified by the referring court – the treatment applied to such officials with effect from 1 January 2019 in relation to family benefits does not differ according to whether or not they have exercised their right to freedom of movement by having left their Member State of origin to settle in Austria, but rather depends exclusively on whether the children of the development aid workers concerned reside in a third country or in another Member State, including in Austria. |

| 78 | That finding is not called into question by the fact that development aid workers who had previously acquired an entitlement to family benefits for periods in the past lost that entitlement further to the entry into force, on 1 January 2019, of the new legislation, since it does not appear that the loss of that entitlement is due to the exercise of their right to free movement, which is for the referring court to verify. |

| 79 | In that regard, it must be added, first, that no relevant guidance for the answer to those questions can be derived from the judgments of 12 June 1980, Laterza (733/79, EU:C:1980:156), and of 26 November 2009, Slanina (C‐363/08, EU:C:2009:732), since the cases that gave rise to those judgments are not comparable in fact or in law to the situation at issue in the case in the main proceedings, as described in the request for a preliminary ruling. Those cases were concerned with changes to entitlements acquired following the exercise, in the territory of the European Union, of the right of free movement by an EU national. However, here, the legislative amendment concerns development aid workers on postings whose children reside with them outside the territory of the European Union. |

| 80 | Second, the possibility, mentioned by the referring court, that the withdrawal of the family allowances for development aid workers may hinder the freedom of movement for workers and, as the case may be, make it less attractive, or even entail a decline in demand for the profession of ‘development aid worker’, even though that would be have to be verified on the facts, cannot, in any case, give rise to a situation that is incompatible with Articles 45 and 48 TFEU. As is clear from paragraphs 71 and 72 of this judgment, those provisions do not harmonise the social security schemes of the Member States, since Member States retain the power to organise their social security systems in accordance with EU law and the FEU Treaty offers no guarantee to a worker that extending his activities into more than one Member State or transferring them to another Member State will be neutral as regards social security. Given the disparities in the social security legislation of the Member States, such an extension or transfer may be more or less advantageous or disadvantageous for the worker in terms of social welfare. It follows that, even where its application is thus less favourable, such legislation is still compatible with Articles 45 and 48 TFEU if it does not place the worker concerned at a disadvantage as compared with those who pursue all their activities in the Member State where it applies or as compared with those who were already subject to it there, and if it does not simply result in the payment of social security contributions on which there is no return (judgment of 14 March 2019, Vester, C‐134/18, EU:C:2019:212, paragraph 32 and the case-law cited). |

| 81 | In the light of those considerations, the eighth and ninth questions must be answered to the effect that Articles 45 and 48 TFEU are to be interpreted as not precluding a Member State from withdrawing, as a general rule, the family benefits that it provided previously to development aid workers who take their family members to the third country to which they have been posted, provided, first, that that withdrawal applies indiscriminately both to recipients who are nationals of that Member State and to recipients who are nationals of other Member States and, second, that the withdrawal entails a difference in treatment between the development aid workers concerned not according to whether or not they exercised their right to free movement before or after that withdrawal, but depending on whether their children reside with them in a Member State or in a third country. |
