| 25 | As the appeal brought by the Europäische Schule München was not successful, it brought an appeal on a point of law (‘Revision’) before the Bundesarbeitsgericht (Federal Labour Court).

| 26 | In that context, the Bundesarbeitsgericht is uncertain as to whether German courts have jurisdiction to deal with the disputes in the main proceedings.

  Is the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools to be interpreted as meaning that the conclusion of a contract between the headteacher of a European school and a part-time teacher concerning the fixed-term nature of the part-time teacher’s employment relationship constitutes an act which is performed by the headteacher in relation to that part-time teacher and which adversely affects the latter? |

| 29 | In this regard, it should be borne in mind that an agreement entered into by the Council of the European Union under Articles 217 TFEU and 218 TFEU is, as far as the European Union is concerned, an act of an EU institution within the meaning of point (b) of the first paragraph of Article 267 TFEU and, as from its entry into force, the provisions of such an agreement form an integral part of the EU legal system; within the framework of that system the Court has jurisdiction to give preliminary rulings concerning the interpretation of such an agreement (see judgment in Demirel, 12/86, EU:C:1987:400, paragraph 7). |

| 32 | First of all, it should be borne in mind that the European schools system is a sui generis system, which achieves, by means of an international agreement, a form of cooperation between the Member States and between those States and the European Union (see judgment in Miles and Others, C‐196/09, EU:C:2011:388, paragraph 39). |

| 33 | It also follows from the case-law that the European schools are an international organisation which, despite the functional links which it has with the European Union, remains formally distinct from it and from its Member States (see, to that effect, judgment in Miles and Others, EU:C:2011:388, paragraph 42). |

| 34 | Therefore, although the Convention defining the Statute of the European Schools constitutes, as far as the European Union is concerned, an act of one of the institutions of the European Union, within the meaning of point (b) of the first paragraph of Article 267 TFEU, it is also governed by international law and, more specifically, as regards its interpretation, by the international law of treaties (see, to that effect, judgment in Brita, C‐386/08, EU:C:2010:91, paragraph 39). |

| 35 | The international law of treaties was consolidated, essentially, in the Vienna Convention. Under Article 1 of that convention, the latter applies to treaties between States. However, under Article 3(b) of that convention, the fact that it does not apply to international agreements concluded between States and other subjects of international law is not to affect the application to such agreements of any of the rules set forth in the Vienna Convention to which they would be subject under international law independently of that convention. |

Question 1

Question 1

| 39 | By Question 1, the referring court asks, essentially, whether the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools must be interpreted as meaning that part-time teachers employed by a European school, who are not seconded by the Member States, are among the persons covered by that provision, unlike the administrative and ancillary staff, who are excluded from it. |

| 40 | In this regard, it must be noted that, under the first sentence of the first subparagraph of Article 27(2) of that convention, as well as under the second subparagraph of Article 27(2) thereof, first, the Complaints Board of the European Schools is to have sole jurisdiction in the first and final instance, once all administrative channels have been exhausted, in any dispute concerning the application of that convention to all persons covered by it, with the exception of administrative and ancillary staff, and, second, the conditions and detailed rules relative to these proceedings are to be laid down, as appropriate, by the Service Regulations for the teaching staff or by the Conditions of Employment for Part-time Teachers. |
| --- | --- |

40

In this regard, it must be noted that, under the first sentence of the first subparagraph of Article 27(2) of that convention, as well as under the second subparagraph of Article 27(2) thereof, first, the Complaints Board of the European Schools is to have sole jurisdiction in the first and final instance, once all administrative channels have been exhausted, in any dispute concerning the application of that convention to all persons covered by it, with the exception of administrative and ancillary staff, and, second, the conditions and detailed rules relative to these proceedings are to be laid down, as appropriate, by the Service Regulations for the teaching staff or by the Conditions of Employment for Part-time Teachers.

| 41 | It follows therefore from the wording of Article 27(2) of the Convention defining the Statute of the European Schools that part-time teachers are among the persons referred to in the first sentence of the first subparagraph of that provision of the Convention, unlike the administrative and ancillary staff, who are excluded. |

41

It follows therefore from the wording of Article 27(2) of the Convention defining the Statute of the European Schools that part-time teachers are among the persons referred to in the first sentence of the first subparagraph of that provision of the Convention, unlike the administrative and ancillary staff, who are excluded.

| 42 | Such an interpretation is also supported by the context of Article 27(2) of the Convention defining the Statute of the European Schools. |
| --- | --- |

42

Such an interpretation is also supported by the context of Article 27(2) of the Convention defining the Statute of the European Schools.

| 43 | As noted by the Commission in its observations, it is clear from that convention, in particular Article 19.4 and 19.6 and the first paragraph of Article 22 thereof, that it draws a clear distinction between the teaching staff, on the one hand, and the administrative and ancillary staff, on the other. |

| 44 | Consequently, the answer to Question 1 is that the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools must be interpreted as meaning that part-time teachers employed by a European school who are not seconded by the Member States are among the persons covered by that provision, unlike the administrative and ancillary staff, who are excluded from it. |

Question 3

Question 3

| 45 | By Question 3, which it is appropriate to examine before Question 2, the referring court asks, essentially, whether the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools must be interpreted as meaning that an agreement concerning the fixed-term nature of the employment relationship contained in the employment contract entered into between the school and the part-time teacher constitutes an act adversely affecting that part-time teacher. |

| 46 | It should be noted, in this regard, that that convention contains no definition of the notion of an ‘act ... adversely affecting’ a person contained in the first sentence of the first subparagraph of Article 27(2) thereof. |

46

It should be noted, in this regard, that that convention contains no definition of the notion of an ‘act ... adversely affecting’ a person contained in the first sentence of the first subparagraph of Article 27(2) thereof.

| 47 | As noted by the Europäische Schule München and the Commission, there is a discrepancy between the different language versions of that convention in regard to the words ‘act ... adversely affecting’, some of which, including the Spanish, English, French and Italian versions, use, respectively, the words ‘un acto’, ‘any act’, ‘un acte’ and ‘un atto’, which are broader in scope than that used in the German version, namely ‘Entscheidung’, or, literally, ‘decision’. |

| 48 | In that regard, it must be recalled that, according to the fifth indent of the fourth recital in the preamble to the Convention defining the Statute of the European Schools, that convention has, among its objectives, that of providing to the teaching staff, as well as to other persons covered by that convention, adequate legal protection against acts of the Board of Governors or the Administrative Boards. |

| 49 | Since nothing, moreover, in the convention or in the measures adopted to give it effect, which must be taken into account by reason of Article 31(3)(c) of the Vienna Convention, opposes it, it is appropriate, having regard in particular to the objective reiterated in the preceding paragraph of the present judgment, to favour, in the present case, a broad interpretation of the notion of an ‘act ... adversely affecting’ a person. |

| 50 | It should be noted that, in accordance with the second subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools, the Conditions of Employment for Part-time Teachers, which determine, inter alia, the conditions and detailed rules relative to proceedings brought before the Complaints Board, provide, in point 3.2, that Article 80 of the Regulations for Members of the Seconded Staff, which features in Title VII thereof, dealing with appeals, applies to part-time teachers, as the Complaints Board of the European Schools has sole jurisdiction in the first and final instance in any dispute between the management organs of the European schools and part-time teachers regarding the legality of ‘any ... act adversely affecting’ the latter. |

It should be noted that, in accordance with the second subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools, the Conditions of Employment for Part-time Teachers, which determine, inter alia, the conditions and detailed rules relative to proceedings brought before the Complaints Board, provide, in point 3.2, that Article 80 of the Regulations for Members of the Seconded Staff, which features in Title VII thereof, dealing with appeals, applies to part-time teachers, as the Complaints Board of the European Schools has sole jurisdiction in the first and final instance in any dispute between the management organs of the European schools and part-time teachers regarding the legality of ‘any ... act adversely affecting’ the latter.

| 51 | In this regard, it is clear that Article 80(1) of the Regulations for Members of the Seconded Staff is formulated in a manner analogous to Article 91 of the Staff Regulations of Officials of the European Communities (Regulation (EEC, Euratom, ECSC) No 259/68 of the Council of 29 February 1968 laying down the Staff Regulations of Officials and the Conditions of Employment of Other Servants of the European Communities and instituting special measures temporarily applicable to officials of the Commission (OJ, English Special Edition 1968(I), p. 30)), under which the Court of Justice of the European Union is to have jurisdiction in any dispute between the European Union and any person to whom the Staff Regulations apply with regard to the legality of an act adversely affecting such a person within the meaning of Article 90(2) thereof. |

| 53 | According to established case-law of the Court, only acts which directly and individually affect the legal position of the persons concerned may be regarded as acts adversely affecting them. Likewise, the Court has repeatedly interpreted the expression ‘act adversely affecting’ a person, within the meaning of Article 90 of the Staff Regulations of Officials of the European Union, as referring to any act that is capable of directly affecting an official’s legal position (see, inter alia, order in Strack v Commission, C‐237/06 P, EU:C:2007:156, paragraph 62 and the case-law cited). |

| 55 | Consequently, the employment contract of a part-time teacher must be regarded as constituting an ‘act adversely affecting’ that person within the meaning of Article 80 of the Regulations for Members of the Seconded Staff, a fortiori where, as in the present case, the matter in issue is an element of the contract imposed by the applicable law, such as its duration, which arises directly from the application of point 1.3 of the Conditions of Employment for Part-time Teachers. |

| 56 | In the light of the foregoing, the answer to Question 3 is that the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools must be interpreted as not precluding an agreement concerning the fixed-term nature of the employment relationship, contained in the employment contract concluded between the school and the part-time teacher, from being regarded as constituting an act adversely affecting that part-time teacher. |

Question 2

Question 2

| 57 | By Question 2, the referring court asks whether the first sentence of the first subparagraph of Article 27(2) of the Convention on the Statute of the European Schools must be interpreted as meaning that an act carried out by the headteacher of the school in the exercise of his powers comes under that provision. |

| 58 | It must be noted that the mere fact that the acts of the headteacher are not expressly mentioned in the first sentence of the first subparagraph of Article 27(2) of that convention cannot have the effect of excluding them from the scope of that provision. |

It must be noted that the mere fact that the acts of the headteacher are not expressly mentioned in the first sentence of the first subparagraph of Article 27(2) of that convention cannot have the effect of excluding them from the scope of that provision.

| 59 | First, it must be recalled that, under the second subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools, the conditions and detailed rules relative to proceedings brought before the Complaints Board are to be laid down, as appropriate, in particular by the Service Regulations for the teaching staff or by the Conditions of employment for part-time teachers. |

| 60 | Second, the Convention defining the Statute of the European Schools must be interpreted, in particular, in accordance with Article 31 of the Vienna Convention, under which it is appropriate to take into account any relevant rules of international law applicable in the relations between the parties and to attach great importance to any subsequent practice in the application of the Convention defining the Statute of the European Schools. |

| 61 | In that regard, as is clear from the case-law of the International Court of Justice, the subsequent practice followed in the application of a treaty may override the clear terms of that treaty if that practice reflects the parties’ agreement (ICJ, Case concerning the Temple of Preah Vihear (Cambodia v Thailand), judgment of 15 June 1962, ICJ Reports 1962, p. 6). |

| 62 | Therefore, in order to determine the scope of the words ‘act ... on the part of the board of Governors [or] the Administrative Board of a school’ contained in the first sentence of the first subparagraph of Article 27(2) of the Convention, it is appropriate to refer to any relevant rule of international law applicable in the relations between the parties and to any subsequent practice in the application of the Convention defining the Statute of the European Schools. |

| 63 | In the present case, it should be noted that, under Article 80 of the Regulations for Members of the Seconded Staff, to which point 3.2 of the Conditions of Employment for Part-time Teachers refers and which determines, in accordance with the second subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools, certain conditions and detailed rules relating to proceedings before the Complaints Board of the European Schools, the sole jurisdiction of the latter extends to any dispute between the management organs of the European schools and members of staff regarding the legality of any act which adversely affects the latter. It is clear, in particular from the last paragraph of Article 7 of that convention, read in conjunction with the second paragraph of Article 21 thereof, and from Article 6(a) of and Annex I to the Regulations for Members of the Seconded Staff, that the headteacher of a European school is a management organ of that school. |

In the present case, it should be noted that, under Article 80 of the Regulations for Members of the Seconded Staff, to which point 3.2 of the Conditions of Employment for Part-time Teachers refers and which determines, in accordance with the second subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools, certain conditions and detailed rules relating to proceedings before the Complaints Board of the European Schools, the sole jurisdiction of the latter extends to any dispute between the management organs of the European schools and members of staff regarding the legality of any act which adversely affects the latter. It is clear, in particular from the last paragraph of Article 7 of that convention, read in conjunction with the second paragraph of Article 21 thereof, and from Article 6(a) of and Annex I to the Regulations for Members of the Seconded Staff, that the headteacher of a European school is a management organ of that school.

| 64 | The wording of Article 80 of the Regulations for Members of the Seconded Staff therefore differs from that of the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools. |

The wording of Article 80 of the Regulations for Members of the Seconded Staff therefore differs from that of the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools.

| 65 | The case-law of the Complaints Board of the European Schools has subsequently developed on the basis of Article 80 of the Regulations for Members of the Seconded Staff; according to that case-law, it is possible to bring proceedings against acts adversely affecting an individual carried out by the management organs of the European schools. That case-law should be considered to be a subsequent practice in the application of the Convention defining the Statute of the European Schools within the meaning of Article 31(3)(b) of the Vienna Convention. |

That case-law should be considered to be a subsequent practice in the application of the Convention defining the Statute of the European Schools within the meaning of Article 31(3)(b) of the Vienna Convention.

| 66 | That practice has never been the subject of challenge by the parties to that convention. The absence of any challenge by those parties must be regarded as reflecting their tacit agreement to such a practice. |

That practice has never been the subject of challenge by the parties to that convention. The absence of any challenge by those parties must be regarded as reflecting their tacit agreement to such a practice.

| 67 | It follows that it is appropriate to categorise that practice, based on Article 80 of the Regulations for Members of the Seconded Staff, as establishing the agreement of the parties on the matter of the interpretation of the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools. That same practice is therefore liable to override the wording of Article 27(2) of the Convention, which must therefore be read as not precluding the acts of the management organs of the European schools from, in principle, being regarded as covered by Article 27(2) of the Convention defining the Statute of the European schools. |

| 68 | With regard to the effect of point 3.4 of the Conditions of Employment for Part-time Teachers on the dispute in the main proceedings, it should be borne in mind that, under that provision, the courts of the country in which a European school is situated are to have jurisdiction in any dispute to be resolved concerning the conditions of appointment and dismissal of part-time teachers, teachers of religion and temporary staff who are to be governed by the courts of the country in which that school is situated with respect to employment-relationship, social-security and taxation regulations, without prejudice to the provisions above. |

| 69 | To the extent to which that dispute concerns the limitation of the duration of the employment contract, such as provided for in point 1.3 of the Conditions of Employment for Part-time Teachers, it cannot come within the jurisdiction of the courts of the country in which the European school concerned is situated. Moreover, that finding is also reflected in Article 10(2) of the teaching contracts concluded between the parties to the main proceedings. |

| 70 | It follows that it is appropriate to take the view that points 1.3, 3.2 and 3.4 of the Conditions of Employment for Part-time Teachers must be interpreted as meaning that a dispute as to the legality of an agreement on limiting the duration of the employment relationship included in the employment contract entered into between a part-time teacher and the headteacher of a European school comes within the exclusive jurisdiction of the Complaints Board of the European Schools. |

| 71 | Furthermore, contrary to what Ms Oberto and Ms O’Leary submitted at the hearing, it should be noted that that interpretation of the relevant provisions of the Convention defining the Statute of the European Schools and of the Conditions of Employment for Part-time Teachers, according to which that Complaints Board has exclusive jurisdiction to rule on a dispute such as that at issue in the main proceedings, does not adversely affect the right of the interested parties to effective judicial protection. |

| 72 | So far as the Complaints Board of the European Schools is concerned, the Court has held that it satisfies all of the requirements which must be met in order for a body to be recognised as ‘a court or tribunal’ for the purposes of Article 267 TFEU, in particular that it is established by law, is permanent, its jurisdiction is compulsory, its procedure is inter partes, it applies rules of law and it is independent, with the exception of the requirement that it be a court or tribunal of one of the Member States (see, to that effect, judgment in Miles and Others, EU:C:2011:388, paragraphs 37 to 39). |

| 74 | Finally, although the Court stated in the judgment in Miles and Others (EU:C:2011:388, paragraphs 43 to 45) that it did not have jurisdiction to answer the question raised by the Complaints Board of the European Schools because the latter does not constitute a ‘court or tribunal of a Member State’ within the meaning of Article 267 TFEU, it also accepted the possibility, or indeed the obligation, which that Complaints Board has to refer a question to the Court in the course of a dispute between teachers seconded to a European school and that school, in which it is appropriate to apply the general principles of EU law, but that it was for the Member States to reform the system of judicial protection established by the Convention defining the Statute of the European Schools currently in force. |

| 75 | The view must therefore be taken that the obligation for the respondents in the main proceedings to bring their dispute relating to the legality of an agreement on limiting the duration of the employment relationship included in their employment contracts entered into with the headteacher of the Europäische Schule München before the Complaints Board of the European Schools, which rules in the first and final instance and is not entitled to apply to the Court for a preliminary ruling, does not affect the respondents’ right to effective judicial protection. |

| 76 | In the light of the foregoing, the answer to Question 2 is that the first sentence of the first subparagraph of Article 27(2) of the Convention defining the Statute of the European Schools must be interpreted as not precluding an act carried out by the headteacher of a European school in the exercise of his powers from coming, in principle, within the scope of that provision. Points 1.3, 3.2 and 3.4 of the Conditions of Employment for Part-time Teachers must be interpreted as meaning that a dispute concerning the legality of an agreement on limiting the duration of the employment relationship included in the employment contract concluded between a part-time teacher and that headteacher comes within the exclusive jurisdiction of the Complaints Board of the European Schools. |
