Each residence permit must state whether the taking-up of paid employment has been authorised. A foreign national who is not in possession of a residence permit for the purposes of taking up employment cannot be authorised to take up employment unless the Federal Labour Agency has indicated its agreement or a regulation provides that taking up such employment without that agency’s authorisation is permissible. Any restrictions imposed on the issue of the authorisation by that agency must be mentioned in the residence permit. ...

23. Mr Gülbahce, a Turkish national, married a German national in June 1997. On 8 June 1998, he entered Germany with a visa issued on the ground of family reunification. In July 1998, the German authorities granted him a residence permit which was subsequently extended in June 1999, August 2001 and January 2004. At the same time, on 29 September 1998, the competent employment office granted Mr Gülbahce a work permit of unlimited duration.
24. In July 2005, the German authorities learned that Mr Gülbahce’s wife had made a declaration, in November 1999, that she had been living apart from him since 1 October 1999. After having heard Mr Gülbahce, and by decision of 6 February 2006, which was confirmed by decision of 29 August 2006, the Freie und Hansestadt Hamburg withdrew, with retroactive effect, the extensions of Mr Gülbahce’s residence permit granted in August 2001 and January 2004. According to the Freie und Hansestadt Hamburg, the extensions to Mr Gülbahce’s residence permits were invalid because Mr Gülbahce had not lived in matrimonial cohabitation with his wife for two years. Moreover, Mr Gülbahce was not entitled to have that residence permit extended under the first indent of Article 6(1) of Decision No 1/80 as he had not been employed with the same employer for at least one year.
25. By judgment of 3 July 2007, the Verwaltungsgericht Hamburg (Administrative Court, Hamburg) dismissed the action brought by Mr Gülbahce. On appeal, the Hamburgisches Oberverwaltungsgericht, by a judgment of 29 May 2008, varied that judgment.
26. According to the Hamburgisches Oberverwaltungsgericht, although Mr Gülbahce had not established the existence of matrimonial cohabitation for two years and although he could also not rely on the first indent of Article 6(1) of Decision No 1/80, his residence permit ought to have been extended on account of the combined effect of the work permit of unlimited duration granted to him in September 1998 and Article 10(1) of Decision No 1/80, read in conjunction with the case‑law of the Court of Justice concerning the prohibitions of discrimination laid down in the agreements entered into by the European Union with the Republic of Tunisia and the Kingdom of Morocco.
27. In that regard, the Hamburgisches Oberverwaltungsgericht held that, in so far as Mr Gülbahce was duly registered as belonging to the labour force in both August 2001 and January 2004, the right actually to engage in employment could have been denied to him only on grounds of the protection of a legitimate national interest; such grounds, however, did not exist in the present case.
28. On appeal by the Freie und Hansestadt Hamburg, the Bundesverwaltungsgericht (Federal Administrative Court) set aside, by judgment of 8 December 2009, the judgment of the Hamburgisches Oberverwaltungsgericht of 29 May 2008 and referred the case back to that court for it to rule on the matter afresh.
29. According to the Hamburgisches Oberverwaltungsgericht, the Bundesverwaltungsgericht took the view that Article 10(1) of Decision No 1/80 conferred neither a right to be granted a retroactive resident permit nor a right of residence independent of specific employment. In that regard, the work permit issued before the entry into force of the AufenthG, namely 1 January 2005, only constituted an internal administrative authorisation from that date onwards. In addition, such legislation cannot be found to be contrary to the ‘standstill’ clause in Article 13 of Decision No 1/80 since the granting of a work permit of unlimited duration for spouses of German nationals was introduced by the ArGV only in September 1998, whereas the law in force in 1980, to which Article 13 relates, allowed a work permit of unlimited duration to be issued only after a regular and uninterrupted period of residence of 8 years.
30. The Hamburgisches Oberverwaltungsgericht took the view that an interpretation of European Union law was required to enable it to determine the dispute before it, and accordingly decided to stay the proceedings and to refer the following questions to the Court of Justice for a preliminary ruling: ‘1. Is Article 10(1) of Decision No 1/80 to be interpreted as meaning: (a) that a Turkish worker who has been duly granted a permit to take up employment in the territory of a Member State for a particular period (which may be unlimited) that extends beyond the duration of his residence permit (“overrunning work permit”) may exercise his rights under that permit for the whole of that period provided that this is not precluded on grounds relating to the protection of a legitimate national interest such as public policy, public security or public health; (b) and that a Member State is prohibited from refusing a priori to recognise that permit as having any effect on his residence status on the basis of national provisions in force at the time when the permit was granted which make the work permit dependent on the residence permit (in accordance with the judgments in Case C‑416/96 Eddline El-Yassini [1999] ECR I‑1209, paragraph 3 of the summary of the judgment, paragraphs 62 to 65 of the grounds, concerning the scope of the first paragraph of Article 40 of the [Cooperation Agreement between the European Economic Community and the Kingdom of Morocco, signed in Rabat on 27 April 1976 and approved on behalf of the Community by Council Regulation (EEC) No 2211/78 of 26 September 1978 (OJ 1978 L 264, p. 1)], and Case C‑97/05 Gattoussi [2006] ECR I‑11917, paragraph 2 of the summary of the judgment, paragraphs 36 to 43 of the grounds, concerning the scope of Article 64(1) of the [Euro-Mediterranean Agreement establishing an association between the European Communities and their Member States, on the one hand, and the Republic of Tunisia, on the other, concluded in Brussels on 17 July 1995 and approved on behalf of the European Community and the European Coal and Steel Community by Decision 98/238/EC, ECSC of the Council and the Commission of 26 January 1998 (OJ 1998 L 97, p. 1)])? If that question is answered in the affirmative: 2. Is Article 13 of Decision No 1/80 to be interpreted as meaning that the “standstill” clause also prohibits a Member State, by means of a legislative provision (in this case, [the AufenthG]), from depriving a Turkish worker duly registered as belonging to its labour force of the possibility of relying on a breach of the principle of non-discrimination contained in Article 10(1) of Decision No 1/80 by reason of a work permit previously granted to him for a period extending beyond the duration of the residence permit? If that question is answered in the affirmative: 3. Is Article 10(1) of Decision No 1/80 to be interpreted as meaning that the principle of non-discrimination there laid down does not in any event prohibit the national authorities, in accordance with national provisions, from withdrawing, after their period of validity has expired, residence permits of limited duration wrongfully granted to a Turkish worker under national law for such periods of time during which the Turkish worker actually made use of a work permit of unlimited duration which had previously been duly granted to him and was in employment? 4. Is Article 10(1) of Decision No 1/80 further to be interpreted as meaning that that provision covers only employment in which a Turkish worker who is in possession of a work permit which has been duly granted to him by the national authorities for an unlimited period and without restrictions ratione materiae is engaged at the time when his residence permit, which has been granted for a limited period for a different purpose, expires, and that a Turkish worker in that situation cannot therefore ask the national authorities, even after having permanently left that employment, to grant him a further right of residence for the purposes of new employment - which may be taken up after an interval of time needed to look for another job? 5. Is Article 10(1) of Decision No 1/80 further to be interpreted as meaning that the principle of non-discrimination (only) bars the national authorities of the host Member State from taking measures, after the last-issued residence permit has expired, to repatriate a Turkish national duly registered as belonging to its labour force to whom it originally granted specific rights in relation to employment which were more extensive than his rights of residence, in so far as such measures do not serve to protect a legitimate national interest, but does not require them to issue a residence permit?’ The questions referred for a preliminary ruling
31. At the outset, it should be noted that, even though, formally, the referring court has limited its questions to the interpretation of Articles 10(1) and 13 of Decision No 1/80, such a situation does not prevent the Court from providing the referring court with all the elements of interpretation of European Union law which may be of assistance in adjudicating on the case before it, whether or not that court has specifically referred to them in the questions (see Case C‑251/06 ING. AUER [2007] ECR I‑9689, paragraph 38, and Case C‑434/09 McCarthy [2011] ECR I‑3375, paragraph 24).
32. In that regard, it should be recalled that the Court has consistently held that, in the application of Article 267 TFEU, it may extract from the wording of the questions formulated by the referring court, and having regard to the facts stated by the latter, those elements which concern the interpretation of European Union law, for the purpose of enabling that court to resolve the legal problems before it (Case C‑420/07 Apostolides [2009] ECR I‑3571, paragraph 63 and the case‑law cited).
33. In the present case, the referring court points out in its decision that the withdrawal, with retroactive effect, of the decisions of August 2001 and January 2004 extending the duration of Mr Gülbahce’s residence permit was based on the fact that he had been living apart from his spouse since 1 October 1999, matrimonial cohabitation constituting a condition to which the right of residence was subject pursuant to the combined provisions of the AuslG, the AEVO, the SGB III and the ArGV.
34. The referring court also states that, at the time of that retroactive withdrawal, namely 6 February 2006, Mr Gülbahce had been employed by the same employer for more than one year, with the result that, in principle, the conditions for considering that he was duly registered as belonging to the labour force within the meaning of the first indent of Article 6(1) of Decision No 1/80 were satisfied.
35. It is thus necessary to reformulate the questions referred into one single question which must be understood as seeking, in essence, to ascertain whether the first indent of Article 6(1) of Decision No 1/80 must be interpreted as precluding the competent national authorities from withdrawing the residence permit of a Turkish worker with retroactive effect from the point in time at which there was no longer compliance with the ground on the basis of which his residence permit had been issued under national law if that withdrawal occurs after the completion of the one-year period of legal employment provided for in the first indent of Article 6(1).
36. In that regard, it should be borne in mind that the rights which are conferred on Turkish workers by the provisions set out in Article 6(1) of Decision No 1/80 are progressively extended in proportion to the duration of paid legal employment and are intended to consolidate progressively the position of the persons concerned in the host Member State (see, inter alia, Case C‑230/03 Sedef [2006] ECR I‑157, paragraph 34).
37. As is apparent from the first indent of Article 6(1) of Decision No 1/80, a Turkish worker is entitled, after one year’s legal employment, to continue in paid employment with the same employer.
38. According to the case‑law of the Court, that right, in order to be effective, necessarily implies a concomitant right of residence for the person concerned (see, inter alia, Case C‑383/03 Dogan [2005] ECR I‑6237, paragraph 14).
39. The legality of the employment of a Turkish national in the host Member State, within the meaning of the first indent of Article 6(1) of Decision No 1/80, presupposes a stable and secure situation as a member of the labour force of that Member State and, by virtue of this, implies an undisputed right of residence (Case C‑237/91 Kus [1992] ECR I‑6781, paragraph 22, and Case C‑337/07 Altun [2008] ECR I‑10323, paragraph 53).
40. In the present case, as stated in paragraph 34 above, it is common ground that the condition of legal employment for one year laid down in the first indent of Article 6(1) of Decision No 1/80 had been fulfilled at the date of the retroactive withdrawal of the extensions granted to Mr Gülbahce’s residence permit, namely 6 February 2006.
41. According to the national authorities, such a withdrawal is based on the finding that, on the one hand, that condition had not been fulfilled in August 2001 and January 2004, the times at which extensions were granted to Mr Gülbahce’s residence permit, and, on the other, Mr Gülbahce was no longer, on those dates, in compliance with the condition of matrimonial cohabitation with a German national to which his residence permit was subject.
42. Consequently, according to the national authorities, if a Turkish worker no longer complies, in the course of the first year of employment, with the conditions subject to which his residence permit has been issued to him, his right of residence is no longer uncontested, with the result that, as from that point in time, the periods of work completed by that worker cannot be taken into account for the purpose of the acquisition of the rights referred to in the first indent of Article 6(1) of Decision No 1/80 on the ground that that worker does not comply with the condition of one year’s legal employment in accordance with the Court’s case‑law.
43. However, such an argument has been expressly rejected by the Court, specifically with regard to provisions of national law which made a Turkish national’s right to residence subject to matrimonial cohabitation with a national of the Member State concerned.
44. In its judgment of 29 September 2011 in Case C‑187/10 Unal [2011] ECR I‑9045, delivered after the reference for a preliminary ruling had been made in the present case, the Court has already had occasion to hold that, in the case where a Turkish national may legitimately rely on rights pursuant to a provision of Decision No 1/80, those rights are no longer dependent on the continuing existence of the circumstances which gave rise to them, as no condition of that nature is laid down by that decision ( Unal , paragraph 50).
45. In that regard, it was pointed out that, under the first indent of Article 6(1) of Decision No 1/80, a Turkish worker needs only to have been in legal employment for more than one year in order to be entitled to the renewal of his permit to work for the same employer, since that provision does not make recognition of that right dependant on any other condition, such as the circumstances under which the right of entry and residence was obtained ( Unal , paragraph 38 and the case‑law cited).
46. Thus, the Court held that a Turkish worker who has been employed for more than one year under a valid work permit has to be regarded as fulfilling the conditions laid down in the first indent of Article 6(1) of Decision No 1/80, even though his residence permit had initially been granted to him for a purpose other than that of engaging in paid employment ( Unal , paragraph 39 and the case‑law cited).
47. It is true that, as European Union law stands at present, Decision No 1/80 do es not at all encroach upon the competence of the Member States to refuse Turkish nationals the right of entry into their territories and to take up first employment there. Nor does that decision preclude those Member States, in principle, from regulating the conditions under which those persons work for up to one year as provided for in the first indent of Article 6(1) of Decision No 1/80 (see Unal , paragraph 41 and the case‑law cited).
48. Article 6(1) of Decision No 1/80 cannot, however, be construed as permitting a Member State to modify unilaterally the scope of the system of gradual integration of Turkish workers in the host Member State’s labour force by denying to a worker who has been permitted to enter its territory and who has lawfully pursued a genuine and effective economic activity for a continuous period of more than one year with the same employer the rights which the three indents of that provision confer on him progressively according to the duration of his employment (see Unal , paragraph 42 and the case‑law cited).
49. Such an interpretation would render Decision No 1/80 meaningless and deprive it of any practical effect, since the wording of Article 6(1) of that decision is general and unconditional in that it does not permit the Member States to restrict the rights which that provision confers directly on Turkish workers ( Unal , paragraphs 43 and 44 and the case‑law cited).
50. It is true that the employment of a Turkish national under a residence permit which was issued to him as a result of fraudulent conduct which has led to a conviction or under a provisional residence permit which is valid only pending a final decision on his right of residence cannot give rise to any rights in favour of that national under Article 6(1) of Decision No 1/80 (see Unal , paragraph 47).
51. However, in the case in the main proceedings, and in contrast to the case which gave rise to the judgment in Case C‑285/95 Kol [1997] ECR I‑3069, which involved a sham marriage, it is not apparent from the order for reference that Mr Gülbahce was employed under a residence permit which had been issued to him as a result of fraudulent conduct or that his residence permit was valid only pending a final decision.
52. In addition, under Paragraph 2(1)(2) of the AEVO and Paragraphs 2(1)(1) and 5 of the ArGV, Mr Gülbahce had a right of residence which allowed him to engage freely in paid employment from 29 September 1998, that is to say, the date on which the competent employment office granted him a work permit of unlimited duration. The referring court has stated in that regard that it has not been found that Mr Gülbahce’s right to enter and reside in Germany was obtained by fraud.
53. It is not, therefore, in dispute that Mr Gülbahce complied with the conditions laid down by law or regulation in the host Member State as far as entry into its territory and employment were concerned.
54. In those circumstances, not to accept that Mr Gülbahce has been legally employed in Germany for more than one year would be contrary to the first indent of Article 6(1) of Decision No 1/80.
55. Consequently, the periods of employment which were completed by Mr Gülbahce after he had obtained a residence and work permit, and before the withdrawal, with retroactive effect, of the decisions extending the duration of that residence permit, must be regarded as satisfying the condition of one year’s legal employment within the meaning of the first indent of Article 6(1) of Decision No 1/80.
56. In the light of the foregoing, the answer to the questions referred, as reformulated by the Court, is that the first indent of Article 6(1) of Decision No 1/80 must be interpreted as precluding the competent national authorities from withdrawing the residence permit of a Turkish worker with retroactive effect from the point in time at which there was no longer compliance with the ground on the basis of which his residence permit had been issued under national law if there is no question of fraudulent conduct on the part of that worker and that withdrawal occurs after the completion of the period of one year of legal employment provided for in the first indent of Article 6(1) of Decision No 1/80. Costs
57. Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the referring 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.
