“(1) Whereas, pursuant to Article 3(c) of the Treaty, the abolition, as between Member States, of obstacles to the free movement of persons and services constitutes one of the objectives of the Community;… (3) Whereas the completion of the internal market offers a dynamic environment for the transnational provision of services, prompting a growing number of undertakings to post employees abroad temporarily to perform work in the territory of a Member State other than the State in which they are habitually employed;… (5) Whereas any such promotion of transnational provision of services requires a climate of fair competition and measures guaranteeing respect for the rights of workers;… (20) Whereas this Directive does not affect either the agreements concluded by the Community with third countries or the laws of Member States concerning the access to their territory of third-country providers of services; whereas this Directive is also without prejudice to national laws relating to entry, residence and access to employment of third-country workers;… Article 1 Scope This Directive shall apply to undertakings established in a Member State which, in the framework of the transnational provision of services, post workers, in accordance with paragraph 3, to the territory of a Member State… Article 2 Definition 1. For the purposes of this Directive, ‘posted worker’ means a worker who, for a limited period, carries out his work in the territory of a Member State other than the State in which he normally works.”
“16. Finally, as one of the fundamental principles of the Treaty, freedom to provide services may be restricted only by rules which are justified by overriding reasons in the general interest and are applied to all persons and undertakings operating in the territory of the State where the service is provided, in so far as that interest is not safeguarded by the rules to which the provider of such a service is subject in the Member State where he is established… 18. In all the circumstances, it is important to note, first, that the Moroccan workers employed by Mr Vander Elst were lawfully resident in Belgium, the State in which their employer was established and where they had been issued with work permits. 19. Secondly, it is apparent from the documents and hearings before the Court that the short-stay visas held by the persons concerned, issued by the French Consulate at their request, constituted valid documents permitting them to remain in France for as long as was necessary to enable them to carry out the work. Consequently the national legislation applicable in the host State concerning the immigration and residence of aliens had been complied with… 21. Workers employed by an undertaking established in one Member State who are temporarily sent to another Member State to provide services do not in any way seek access to the labour market in that second State, if they return to their country of origin or residence after completion of their work…Those conditions were fulfilled in the present case… 26. The answer to the questions referred to the Court must therefore be that Articles 59 and 60 of the Treaty are to be interpreted as precluding a Member State from requiring undertakings which are established in another Member State and enter the first Member State in order to provide services, and which lawfully and habitually employ nationals of non-member countries, to obtain work permits for those workers from a national immigration authority and to pay the attendant costs, with the imposition of an administrative fine as the penalty for infringement.”
“31. A measure which would be just as effective whilst being less restrictive than the measure at issue here would be an obligation imposed on a service-providing undertaking to report beforehand to the local authorities on the presence of one or more of the deployed workers, the anticipated duration of their presence and the provision or provisions of services justifying the deployment. It would enable those authorities to monitor compliance with the Luxembourg social welfare legislation during the deployment whilst at the same time taking account of the obligations whereby the undertaking is already bound under the social welfare legislation applicable in the Member State of origin… 38. It should in this regard be borne in mind that, although the desire to avoid disturbances on the labour market is undoubtedly an overriding reason of general interest (see, to that effect C-113/89 Rush Portuguesa[1990] ECR I-1417 , paragraph 13), workers employed by an undertaking established in a Member State and who are deployed to another Member State for the purpose of providing services there do not purport to gain access to the labour market of that second State, as they return to their country of origin or residence after the completion of their work… 46. An obligation imposed on a service-providing undertaking to provide the local authorities with information showing that the situation of the workers concerned is lawful as regards matters such as residence, work permit and social coverage in the Member State in which that undertaking employs them would give those authorities, in a less restrictive but just as effective a manner as the requirements in issue here, a guarantee that the situation of those workers is lawful and that they are carrying on their main activity in the Member State in which the service providing undertaking is established…”
“28. I would add that, in general, undertakings intending to operate temporarily on the territory of another Member State with workers from third countries must bear responsibility for ensuring that these employees are legally resident in the Member State of establishment and that their employment conditions are in line with the relevant social legislation. To the extent that legal certainty may be invoked as a separate ground of general interest, which I doubt, it cannot be used to justify the fact that these prior controls provide service providers from other Member States with clarity beforehand. It must be presumed that bona fide undertakings operate in compliance with the applicable immigration and social legislation of the Member State of establishment. The host Member State may apply its own social legislation to service providers from other Member States to the extent that it provides further protection than that of the Member State of establishment of the service provider. In these circumstances, it is more appropriate that the host Member State restrict its intervention to verifying the requisite information provided by the service provider on commencing activities in the host Member State and to take repressive action where this proves necessary.”
“35. However, as the Advocate General observed in point 27 of his Opinion, a requirement that the service provider furnishes a simple prior declaration certifying that the situation of the workers concerned is lawful, particularly in the light of the requirements of residence, work visas and social security cover in the Member State where that provider employs them, would give the national authorities, in a less restrictive but as effective a manner as checks in advance of posting, a guarantee that those workers situation is lawful and that they are carrying on their main activity in the Member State where the service provider is established… 49. It is certainly in the interest of both the host Member State and the service provider to have, prior to the posting, the assurance that workers who are nationals of a non-member State are posted lawfully. 50. However, as the Advocate General noted in point 28 of his Opinion, it is for undertakings which do not comply with that legislation to bear the responsibility for a posting effected unlawfully. 51. Accordingly, the check in advance practised by the German authorities in respect of the posting of workers who are nationals of a non-member state cannot be justified by the necessity of ensuring that the posting is effected lawfully, and, therefore, it is a disproportionate means having regard to the objectives pursued by the Federal Republic of Germany… 55…In that regard [the Vander Elst requirement of lawful and habitual employment], it must be observed that the Court did not couple the concept of ‘lawful and habitual employment’ with a requirement of residence or employment for a certain period in the State of establishment of the service provider.”
“75. There is, in my view, no genuine posting of workers in these cases, there has been an improper attempt to invoke community rights, and there has been, in particular, an attempt by the Irish company to wrongfully secure an advantage over companies in UK. This case is an example of the abusive practices as explained by the court [the ECJ] in Halifax [plc v. Commissioners of Customs and ExciseCase C-255/02 [2006] 2 CMLR 36 ] at para 69 of the judgment in particular: “The application of community legislation cannot be extended to cover abusive practices by economic operators, that is to say transactions carried out not in the context of normal commercial operations, but solely for the purpose of wrongfully obtaining advantages provided for by Community law… 80. For the reasons which I have set out above, there is no European authority that supports [the claimants’ counsel’s] proposition. Article 49 is not engaged, but even if it were to be, it is my finding that the scheme is an abuse of European community law, and the [Secretary of State] has made no error of law in calling the scheme in the decision letter “spurious”.”
“13. Likewise, a Member State cannot be denied the right to take measures to prevent the exercise by a person providing services whose activity is entirely or principally directed towards its territory of the freedom guaranteed by Article 59 [49] for the purpose of avoiding the professional rules of conduct which would be applicable to him if he were established within that state...”
“68. …it must be borne in mind that, according to settled case-law, Community law cannot be relied on for abusive or fraudulent ends (see, in particularCase C-367/96 Kefalas and Others[1998] ECR I-2843 , paragraph 20;Case C-373/97 Diamantis[2000] ECR I-1705 , paragraph 33; andCase C-32/03 Fini H[2005] ECR I-1599 , paragraph 32). “69. The application of Community legislation cannot be extended to cover abusive practices by economic operators, that is to say transactions carried out not in the context of normal commercial operations, but solely for the purpose of wrongly obtaining advantages provided by Community law (see, to that effect, Case 125/76 Cremer [1977] ECR 1593, paragraph 21;Case C-8/92 General Milk Products[1993] ECR I-779 , paragraph 21; and Emsland-Stärke, paragraph 51).”
