29In those circumstances, the Bezirksgericht Linz decided to stay the proceedings and to refer the following questions to the Court for a preliminary ruling:1.(a) Are Articles 43 EC and 49 EC to be interpreted as in principle precluding legislation of a Member State, such as Paragraph 3 in conjunction with Paragraph 14 et seq. and Paragraph 21 of the [GSpG], under which— a concession for lotteries (e.g. lotteries, electronic lotteries, etc.) may be granted only to a single applicant for a period of up to 15 years, and the applicant must inter alia be a capital company established in Austria, must not set up branches outside Austria, must have a paid-up nominal or share capital of at least EUR 109000000, and may in the circumstances be expected to achieve the best yield in terms of federal taxation;— a concession for casinos may be granted to no more than 12 applicants for a period of up to 15 years, and an applicant must inter alia be a share company established in Austria, must not set up branches outside Austria, must have a paid-up share capital of EUR 22000000, and may in the circumstances be expected to achieve the best yield in terms of taxation for the local authorities?These questions arise particularly against the background that [Casinos Austria] holds all 12 casino concessions, which were granted on 18 December 1991 for the maximum period of 15 years and have since been extended without a public tendering procedure or notice.(b) If so, can such legislation be justified for reasons in the public interest in a restriction of betting activities even if the holders of concessions in a quasi-monopoly structure for their part pursue an expansionist policy in the field of games of chance by means of an intensive advertising effort?(c) If so, must the referring court, when examining the proportionality of such legislation, which aims to prevent criminal offences by monitoring the economic operators active in this sector and thereby steering gaming activities into channels subject to such monitoring, take account of the fact that the legislation also covers cross-border service providers who are subject in any event in the Member State of establishment to the strict obligations and checks associated with their concessions?2. Are the fundamental freedoms of the EC Treaty, in particular the freedom to provide services under Article 49 EC, to be interpreted as meaning that, irrespective of the fact that the Member States in principle remain competent for the regulation of criminal law, a provision of a Member State’s criminal law is nevertheless to be measured against Community law if it is liable to prohibit or obstruct the exercise of one of the fundamental freedoms?3.(a) Is Article 49 EC in conjunction with Article 10 EC to be interpreted as meaning that the checks carried out in a service provider’s State of establishment, and the safeguards provided there, must be taken into account in the State in which the services are provided, on the basis of the principle of mutual trust?(b) If so, is Article 49 EC to be interpreted further as meaning that, where the freedom to provide services is restricted for reasons in the public interest, consideration must be given to whether sufficient account is not already taken of this public interest by the legal provisions, checks and investigations to which the service provider is subject in the State in which he is established?(c) If so, when examining the proportionality of a provision of a Member State imposing penalties for the cross-border provision of gaming services without a licence granted in that State, must consideration be given to the fact that the regulatory interests on which the State in which the services are provided relies in order to justify the restriction of the fundamental freedom are already sufficiently taken into account in the State of establishment by a strict authorisation and supervision procedure?(d) If so, must the referring court take account, in the context of its examination of the proportionality of such a restriction, of the fact that the relevant provisions of the State in which the service provider is established provide for a degree of control which actually exceeds that of the State in which the services are provided?(e) Does the principle of proportionality, in the case of a prohibition on pain of criminal penalties of games of chance that is imposed for regulatory reasons such as the protection of gamblers and the fight against crime, further require the referring court to draw a distinction between providers who offer games of chance without any authorisation whatsoever and those who are established and hold concessions in other Member States of the European Union and conduct their activities in the exercise of their freedom to provide services?(f) In the examination of the proportionality of a provision of a Member State prohibiting on pain of criminal penalties the cross-border provision of gaming services without a concession or authorisation granted in that State, must account be taken, finally, of the fact that, as a result of objective, indirectly discriminatory barriers to access, it was not possible for a provider of games of chance duly licensed in another Member State to obtain a licence in the first Member State, and the licensing and supervisory procedure in the State of establishment offers a level of protection that is at least comparable to that of the first Member State?4.(a) Is Article 49 EC to be interpreted as meaning that the temporary nature of the provision of services precludes the service provider from equipping himself with a certain infrastructure (such as a server) in the host Member State without being regarded as established in that Member State?(b) Is Article 49 EC to be interpreted further as meaning that a prohibition directed at support service providers within a Member State of facilitating the provision of services by a provider established in another Member State constitutes a restriction of that service provider’s freedom to provide services even if the support service providers are established in the same Member State as some of the recipients of the service?’
