Judgment

Legal context and the dispute

1This request for a preliminary ruling concerns the interpretation of Article 4(3) TEU, Articles 107 and 267 TFEU, the principles of fiscal neutrality and effectiveness and Article 135(1)(i) of Council Directive 2006/112/EC of 28 November 2006 on the common system of value added tax (OJ 2006 L 347, p. 1).

2The request has been made in proceedings between Casino de Spa SA and 26 other applicants, on the one hand, and the État belge (SPF Finances) (Federal Public Finance Service, Belgium), on the other, concerning a decision relating to the value added tax (VAT) payable for the period from 1 July 2016 to 21 May 2018, as well as fines and late interest payments in relation to that VAT payable.

Legal context

European Union law

3Article 135(1)(i) of Directive 2006/112 provides:

‘Member States shall exempt the following transactions:

…

betting, lotteries and other forms of gambling, subject to the conditions and limitations laid down by each Member State.’

Belgian law

4Article 1(14) of the code de la taxe sur la valeur ajoutée (Value Added Tax Code) (Moniteur belge of 17 July 1969, p. 7046), as amended by the loi-programme du 1er juillet 2016 (Programme-Law of 1 July 2016),was worded as follows:

‘For the purposes of this Code, the following definitions shall apply:

1° “games of chance or gambling”:

games, under whatever name, which offer the chance to win prizes or awards in cash or in kind, and in which the players cannot intervene either at the beginning, during or at the end of the game, and the winners are determined solely by luck or by any other circumstance due to chance;

games, under whatever name, which offer participants in a competition of any kind the chance to win prizes or awards in money or in kind, unless the competition leads to the conclusion of a contract between the winners and the organiser of that competition;

2° “lotteries”: every circumstance which permits the purchase of lottery tickets, to compete for prizes or awards in cash or in kind, where the winners are determined by luck or by any other circumstances due to chance, over which they cannot exercise any influence.’

5Article 44(3) of the Value Added Tax Code, as amended by the Programme-Law of 1 July 2016, provides:

‘The following shall also be exempt from the tax:

…

13°

lotteries;

other forms of gambling, with the exception of those provided electronically as referred to in Article 18(1)(2)(16)’.

The dispute in the main proceedings and the questions referred for a preliminary ruling

6Casino de Spa and the other applicant companies in the main proceedings form the VAT group Gaming Ardent and offer online gambling.

7That activity was exempt from VAT in Belgium until 1 July 2016, when provisions were adopted repealing the VAT exemption for online gambling other than lotteries.

8Those provisions were annulled by the Cour constitutionnelle (Constitutional Court, Belgium), by judgment of 22 March 2018, on account of the infringement of rules allocating powers between the Federal State of Belgium and the Belgian regions laid down by Belgian law. In that judgment, that court did not examine the other pleas put forward before it, in particular those alleging infringement of Directive 2006/112, the principle of fiscal neutrality and Articles 107 and 108 TFEU, taking the view that those pleas could not lead to a more extensive annulment of those provisions. In that judgment, that court also decided to maintain the effects of those provisions by referring to the budgetary and administrative difficulties which the refund of taxes already paid would cause.

9In a judgment of 8 November 2018, the Cour constitutionnelle (Constitutional Court) stated that the effects of the provisions repealing the VAT exemption for online gambling other than lotteries, which it annulled by its judgment of 22 March 2018, were maintained in respect of taxes which had been paid for the period from 1 July 2016 to 21 May 2018.

10Following those judgments, in the part of its VAT return for September 2019, relating to the VAT adjustments in its favour, the VAT group Gaming Ardent entered an amount of EUR 29 328 371.20, which corresponds to the amount of VAT paid for the period from 1 July 2016 to 21 May 2018, and requested a refund of a balance of VAT of EUR 15 581 402.06.

11On 5 December 2019, an assessment was issued by the Belgian tax authority, in which they stated that that request was contrary to the judgments of the Cour constitutionnelle (Constitutional Court) of 22 March and 8 November 2018 and that, consequently, the VAT group Gaming Ardent owed an amount of EUR 29 328 370.36 in respect of VAT, plus fines and interest payments.

12Following an objection lodged by the VAT group Gaming Ardent against that assessment, the amount of the fines imposed on it was reduced.

13On 12 October 2020, the VAT group Gaming Ardent brought an action before the tribunal de première instance de Liège (Court of First Instance, Liège, Belgium), which is the referring court, against a decision of 14 August 2020 concerning the VAT due for the period from 1 July 2016 to 21 May 2018, fines and late interest payments. It claims, in the alternative, that the Belgian State is liable on account of fault on the part of the Cour constitutionnelle (Constitutional Court), in that that court decided to maintain the effects of the provisions which it annulled and, in the further alternative, the liability of the Belgian State on account of a fault on the part of the legislature.

14In those circumstances, the tribunal de première instance de Liège (Court of First Instance, Liège) decided to stay the proceedings and to refer the following questions to the Court of Justice for a preliminary ruling:

Must Article 135(1)(i) of [Directive 2006/112] and the principle of neutrality be interpreted as precluding a Member State from using different treatment for online lotteries offered by Loterie Nationale [(the Belgian national lottery)], a public establishment, which are exempt from [VAT], and other online games of chance offered by private operators, which are subject to [VAT], assuming that they are similar supplies?

In answering the previous question, in order to determine whether there are two similar categories which are in competition with each other and which require the same treatment for the purposes of [VAT], or whether there are separate categories which allow for different treatment, must the national court consider only whether or not the two forms of games are in competition with each other from the point of view of the average consumer, in the sense that services are similar where they have similar characteristics and meet the same needs from the point of view of consumers, the test being whether their use is comparable, and where the differences between them do not have a significant influence on the decision of the average consumer to use one or the other of those services (alternative criterion), or must it take into account other criteria such as the existence of a discretionary power on the part of the Member State to exempt certain categories of games from VAT and to subject others to it, the fact that lotteries belong to a distinct category of games, referred to in Article 135(1)(i) of [Directive 2006/112], the different legal frameworks which apply to Loterie Nationale and to other games of chance, the different supervisory authorities or the societal and gambler protection objectives pursued by the legislation applicable to Loterie Nationale?

Must the principle of sincere cooperation set out in Article 4(3) TEU, read in conjunction with Article 267 TFEU, the provisions of [Directive 2006/112] and, where applicable, the principle of effectiveness, be interpreted as meaning that they allow the constitutional court of a Member State to maintain – on its own initiative and without a reference for a preliminary ruling under Article 267 TFEU – on the basis of a provision of national law – in this case Article 8 of the loi spéciale du 6 janvier 1989 sur la Cour constitutionnelle (Special Law of 6 January 1989 on the Constitutional Court) – the retrospective effect of national provisions on [VAT] which were found to be contrary to the national Constitution and were annulled on that ground and whose non-conformity with EU law was also relied on in support of the action for annulment before the national court, without, however, that complaint having been examined by the latter, on the general ground of “budgetary and administrative difficulties which repayment of taxes already paid would cause”, thus completely depriving taxable persons subject to VAT of the right to reimbursement of the VAT collected in breach of EU law?

If the answer to the preceding question is in the negative, do the same provisions and principles, interpreted, in particular, in the light of the judgment of 10 April 2008Marks & Spencer, [(C‑309/06, EU:C:2008:211)], under which the general principles of Community law, including that of fiscal neutrality, give a trader who has made supplies a right to recover the sums mistakenly claimed in respect of them (judgment of 10 April 2008, Marks & Spencer, C‑309/06[, EU:C:2008:211)]), require the Member State concerned to refund to the taxable persons the VAT collected in breach of EU law where, as in the present case, it subsequently follows from a judgment of the Court of Justice, in response to questions referred for a preliminary ruling, that the annulled national provisions are not in conformity with [Directive 2006/112] and that the decision of the Constitutional Court to maintain the retrospective effect of the provisions annulled by it is not in conformity with EU law?

Does the different treatment introduced by Articles 29, 30, 31, 32, 33 and 34 of the loi-programme du 1er juillet 2016 (Programme Law of 1 July 2016), which were annulled by Constitutional Court judgment No 34/2018 of 22 March 2018, but the effects of which were maintained after that date in respect of the taxes already paid for the period from 1 July 2016 to 21 May 201[8], between lotteries, whether terrestrial or online, and other online games and forms of betting create a selective advantage in favour of the operators of those lotteries and thus aid granted by the Belgian State or through Belgian State resources which distorts or threatens to distort competition by favouring certain undertakings, which is incompatible with the internal market within the meaning of Article 107 TFEU?

If the answer to the preceding question is in the affirmative, does the obligation on the Member States to safeguard the rights of individuals affected by the unlawful implementation of the aid in question, in accordance with, inter alia, the judgment of 5 October 2006, Transalpine Ölleitung in Österreich, [(C‑368/04, EU:C:2006:644)], the principle of sincere cooperation and the general principles of Community law, including that of fiscal neutrality, which give a trader who has made supplies a right to recover the sums mistakenly charged in respect of them (judgment of 10 April 2008, Marks & Spencer, (C‑309/06[, EU:C:2008:211]), allow taxable persons who have been charged VAT on the basis of unlawful State aid to recover the equivalent of the tax paid in the form of damages for the loss suffered?’

The application to reopen the oral part of the procedure

15After the Advocate General delivered her Opinion at the sitting on 25 April 2024, the applicants in the main proceedings, by letter received at the Court Registry on 30 May 2024, requested the Court to order the reopening of the oral part of the procedure.

16In support of that request, the applicants in the main proceedings submit that the Opinion addresses a question of law relating to the recognition of direct effect in Article 135(1)(i) of Directive 2006/112 which was not submitted to the Court by the referring court and on which the applicants have therefore been unable to submit their observations. They also disagree with the Advocate General’s Opinion on that point.

17In that regard, it should be noted that, in accordance with Article 83 of its Rules of Procedure, the Court may at any time, after hearing the Advocate General, order the reopening of the oral part of the procedure, in particular if it considers that it lacks sufficient information or where the case must be decided on the basis of an argument which has not yet been debated between the parties.

18It must also be borne in mind that the Statute of the Court of Justice of the European Union and the Rules of Procedure make no provision for the parties to submit observations in response to the Advocate General’s Opinion (judgment of 31 January 2023, Puig Gordi and Others, C‑158/21, EU:C:2023:57, paragraph 37 and the case-law cited).

19Furthermore, under the second paragraph of Article 252 TFEU, the Advocate General, acting with complete impartiality and independence, is to make, in open court, reasoned submissions on cases which, in accordance with the Statute of the Court of Justice of the European Union, require the Advocate General’s involvement. The Court is not bound either by the Advocate General’s Opinion or by the reasoning which led thereto. Consequently, a party’s disagreement with the Advocate General’s Opinion, irrespective of the questions that he or she examines in his or her Opinion, cannot in itself constitute grounds justifying the reopening of the oral part of the procedure (judgment of 31 January 2023, Puig Gordi and Others, C‑158/21, EU:C:2023:57, paragraph 38 and the case-law cited).

20In the present case, the Court considers, after hearing the Advocate General, that it has all the information necessary to give a ruling.

21In particular, in the light of the case-law referred to in paragraph 19 above, it should be noted that, contrary to the submissions of the applicants in the main proceedings in support of their request for the reopening of the oral part of the procedure, in so far as the fourth question referred for a preliminary ruling concerns the effects which must be attributed to Article 135(1)(i) of Directive 2006/112 before a national court, the referring court necessarily asked the Court of Justice whether that provision should be recognised as having direct effect. It follows that the applicants had the opportunity to put forward their point of view in that regard.

22Consequently, the Court considers that it is not necessary to order the reopening of the oral part of the procedure.

Consideration of the questions referred

The first and second questions

23By its first and second questions, which it is appropriate to examine together, the referring court asks, in essence, whether Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, must be interpreted as precluding national legislation which differentiates between, on the one hand, the purchase of lottery tickets online and, on the other hand, participation in other forms of gambling offered online, by excluding the latter from the VAT exemption applicable to the former.

24According to Article 135(1)(i) of Directive 2006/112, betting, lotteries and other forms of gambling are exempt from VAT, subject to the conditions and limitations laid down by each Member State.

25It is apparent from the actual wording of that provision that it leaves a broad discretion to the Member States as regards the exemption or the taxation of the transactions concerned since it allows those States to fix the conditions and the limitations to which entitlement to that exemption may be made subject (see, by analogy, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 40 and the case-law cited).

26In addition, the Court has stated that the exercise of the discretionary power of the Member States to fix conditions and limitations on the VAT exemption provided for under that provision allows those States to exempt from that tax only certain forms of betting and gaming (judgment of 24 October 2013, Metropol Spielstätten, C‑440/12, EU:C:2013:687, paragraph 29 and the case-law cited).

27However, when the Member States exercise their power under that provision to lay down the conditions and limitations of the exemption and, therefore, to determine whether or not transactions are subject to VAT, they must respect the principle of fiscal neutrality inherent in the common system of VAT (judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 41 and the case-law cited).

28According to settled case-law, the principle of fiscal neutrality precludes treating similar goods and supplies of services, which are thus in competition with each other, differently for VAT purposes (judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 32 and the case-law cited).

29In order to determine whether two supplies of services are similar, account must be taken of the point of view of the average consumer, avoiding artificial distinctions based on insignificant differences (see, to that effect, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 43 and the case-law cited).

30Two supplies of services are therefore similar where they have similar characteristics and meet the same needs from the point of view of consumers, the test being whether their use is comparable, and where the differences between them do not have a significant influence on the decision of the average consumer to use one such service or the other (judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 44 and the case-law cited).

31In other words, it is necessary to determine whether the services at issue are interchangeable from the point of view of the average consumer. If that is the case, a difference in treatment for VAT purposes might affect the consumer’s choice, which, in turn, would indicate an infringement of the principle of fiscal neutrality (see, to that effect, judgment of 3 February 2022, Finanzamt A, C‑515/20, EU:C:2022:73, paragraph 45 and the case-law cited).

32In that regard, it is necessary to take account of not only the differences in the characteristics of the services at issue and the use of those services which are, therefore, inherent to those services, but also the differences relating to the context in which those services are supplied, to the extent that those contextual differences may create a distinction in the eyes of the average consumer, in terms of the satisfaction of his or her own needs, and may, therefore, influence that consumer’s decision (see, to that effect, judgment of 9 September 2021, Phantasialand, C‑406/20, EU:C:2021:720, paragraphs 41 and 42 and the case-law cited).

33Thus, the Court has held that cultural factors, such as customs or traditions, may be relevant in the context of such an examination (see, to that effect, judgment of 9 September 2021, Phantasialand, C‑406/20, EU:C:2021:720, paragraph 44).

34Moreover, the Court has stated, as regards gambling, that differences relating to the minimum and maximum stakes and prizes, the chances of winning, the formats available and the possibility of interaction between the player and the game are liable to have a considerable influence on the decision of the average consumer, as the attraction of games of chance lies chiefly in the possibility of winning (see, to that effect, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 57).

35Such factors may thus be relevant in determining whether the online purchase of lottery tickets and participation in other forms of gambling offered online are similar.

36Although it is for the referring court alone to assess, in the light of the considerations set out in paragraphs 28 to 35 above, whether those services are similar, it is for the Court to provide some useful indications in that regard to enable the referring court to decide the case before it (see, to that effect, judgment of 20 June 2024, GEMA, C‑135/23, EU:C:2024:526, paragraph 32).

37In particular, it should be noted that cultural factors and differences relating to the minimum and maximum stakes and winnings and the chances of winning may create a distinction, in the eyes of the average consumer, between lotteries and other forms of gambling.

38Furthermore, it is apparent from the order for reference that, in accordance with the national legislation at issue in the main proceedings, first, unlike other forms of gambling, in which the abilities of the player, such as skill or knowledge, may have an influence on the likelihood of winning, in the context of lotteries within the meaning of that legislation, the winners are determined solely by chance, without their abilities exercising any influence in that regard. Secondly, in that context, since the winner is determined on a specific date, the period between the purchase of the lottery ticket and the result may be significant.

39Lotteries, as defined by the national legislation at issue in the main proceedings, are accordingly characterised by a combination of a waiting period for the determination of winners and the complete absence of influence of the abilities of players on the outcome of the game.

40Such objective differences in relation to other forms of gambling appear likely to have a considerable influence on the decision of the average consumer to use one or other category of games, which it is, however, for the referring court to ascertain.

41On the other hand, it must be borne in mind that the identity of the providers, the legal form by means of which they exercise their activities, the licensing category the games concerned fall into and the applicable legal regime relating to control and regulation are, as a rule, irrelevant to the assessment of the comparability of those categories of games (see, by analogy, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraphs 46 and 51).

42Similarly, the objectives pursued by the national legislation at issue in the main proceedings and the fact that the lotteries are expressly referred to in Article 135(1)(i) of Directive 2006/112 are, in principle, irrelevant in the context of such an examination, since those factors do not appear capable of giving rise to a difference, in the eyes of the average consumer, in terms of the satisfaction of his or her own needs.

43In the light of the considerations set out in paragraphs 28 to 42 above, it seems, at first glance, that the services taken into consideration in those paragraphs are not similar, which means that a difference in treatment such as that at issue in the main proceedings is compatible with the principle of fiscal neutrality. It is nevertheless for the referring court to ascertain specifically, in the light of all relevant evidence, whether that legislation infringes that principle.

44Consequently, the answer to the first and second questions is that Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, must be interpreted as not precluding national legislation which differentiates between, on the one hand, the purchase of lottery tickets online and, on the other hand, participation in other forms of gambling offered online, by excluding the latter from the VAT exemption applicable to the former, provided that the objective differences between those two categories of gambling are liable to have a considerable influence on the decision of the average consumer to use one or other of those categories of games.

The third question

45By its third question, the referring court asks, in essence, whether the principle of sincere cooperation, as enshrined in Article 4(3) TEU, read in conjunction with Article 267 TFEU, Directive 2006/112 and the principle of effectiveness, must be interpreted as meaning that a national court against whose decisions there is no judicial remedy may make use of a national provision empowering it to maintain the effects of national provisions which it has held to be incompatible with the higher-ranking rules of its national law, without examining a claim that those provisions are also incompatible with that directive.

46According to settled case-law, in the procedure laid down by Article 267 TFEU providing for cooperation between national courts and the Court of Justice, it is for the latter to provide the national court with an answer which will be of use to it and enable it to decide the case before it. To that end, the Court should, where necessary, reformulate the questions referred to it (judgment of 16 May 2024, Toplofikatsia Sofia (Concept of the defendant’s domicile), C‑222/23, EU:C:2024:405, paragraph 63 and the case-law cited).

47The Court may extract from all the information provided by the national court, in particular from the grounds of the decision to make the reference, the legislation and the principles of EU law that require interpretation in view of the subject matter of the dispute in the main proceedings (judgment of 21 March 2024, Dyrektor Izby Administracji Skarbowej w Bydgoszczy (Possibility of adjustment in the case of incorrect rate), C‑606/22, EU:C:2024:255, paragraph 20 and the case-law cited).

48In the present case, although the third question concerns the obligations which EU law imposes on a national court against whose decisions there is no judicial remedy, it is apparent from the order for reference that that question is referred by a national court of first instance, which is uncertain as to the consequences of the possible incompatibility with Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, of a national provision which has been annulled by the constitutional court of its Member State on the ground of infringement of higher-ranking rules of its national law, the effects of which have been maintained by that constitutional court.

49In that context, it thus appears that the referring court is called upon, in the main proceedings, not to rule directly on the conduct of the constitutional court of its Member State, but, where necessary, to draw the appropriate inferences from the incompatibility of that national provision with EU law in a dispute between a taxable person and a tax authority concerning the amount of VAT payable by that taxable person.

50In those circumstances, it is necessary to reformulate the third question referred for a preliminary ruling to the effect that, by that question, the referring court asks, in essence, whether the principle of sincere cooperation as enshrined in Article 4(3) TEU and the principle of the primacy of EU law require the national court to disapply the national provisions held to be incompatible with Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, the existence of a judgment of the national constitutional court deciding to maintain the effects of those national provisions being irrelevant in that regard.

51It is clear from the settled case-law of the Court that, under the principle of cooperation in good faith laid down in Article 4(3) TEU, Member States are required to nullify the unlawful consequences of a breach of European Union law, and that such an obligation is owed, within the sphere of its competence, by every organ of the Member State concerned (judgment of 5 October 2023, Osteopathie Van Hauwermeiren, C‑355/22, EU:C:2023:737, paragraph 27 and the case-law cited).

52Therefore, where the authorities of the Member State concerned find that national legislation is incompatible with EU law, while they retain the choice of the measures to be taken, they must ensure that national law is brought into line with EU law as soon as possible, and that the rights which individuals derive from EU law are given full effect (judgment of 5 October 2023, Osteopathie Van Hauwermeiren, C‑355/22, EU:C:2023:737, paragraph 28 and the case-law cited).

53It should also be recalled that, in accordance with the principle of the primacy of EU law, the national court called upon within the exercise of its jurisdiction to apply provisions of EU law is under a duty, where it is unable to interpret national law in compliance with the requirements of EU law, to give full effect to the requirements of EU law in the dispute brought before it, by disapplying, as required, of its own motion, any national rule or practice, even if adopted subsequently, that is contrary to a provision of EU law with direct effect, without it having to request or await the prior setting aside of that national rule or practice by legislative or other constitutional means (judgment of 22 February 2022, RS (Effect of the decisions of a constitutional court), C‑430/21, EU:C:2022:99, paragraph 53 and the case-law cited).

54Article 135(1)(i) of Directive 2006/112 has direct effect (see, by analogy, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraphs 69 and the case-law cited).

55It is true that, as has been pointed out in paragraph 25 above, that provision leaves the Member States a broad discretion when adopting legislation laying down the conditions and fixing the limitations of the VAT exemption provided for in that provision.

56That being so, the fact that the Member States have, under a provision of a directive, a margin of discretion does not preclude judicial review from being carried out in order to ascertain whether the national authorities have exceeded that discretion (see, to that effect, judgments of 9 October 2014, Traum, C‑492/13, EU:C:2014:2267, paragraph 47; of 8 March 2022, Bezirkshauptmannschaft Hartberg-Fürstenfeld (Direct effect), C‑205/20, EU:C:2022:168, paragraph 30; and of 27 April 2023, M.D. (Ban on entering Hungary), C‑528/21, EU:C:2023:341, paragraph 98).

57The limits of that margin of discretion result, in particular, from the principle of fiscal neutrality. Accordingly, the Court has held previously that, where the conditions or limitations which a Member State imposes on the exemption from VAT for games of chance or gambling are contrary to the principle of fiscal neutrality, that Member State cannot rely on such conditions or limitations to refuse an operator of such games the exemption which he or she may legitimately claim under Directive 2006/112 (see, to that effect, judgment of 10 November 2011, The Rank Group, C‑259/10 and C‑260/10, EU:C:2011:719, paragraph 68).

58It must also be borne in mind that only the Court may, in exceptional cases, on the basis of overriding considerations of legal certainty, allow the temporary suspension of the ousting effect of a rule of EU law with respect to national law that is contrary thereto. Such a restriction on the temporal effects of the interpretation of that law, made by the Court, may be granted only in the actual judgment ruling upon the interpretation requested (judgment of 5 October 2023, Osteopathie Van Hauwermeiren, C‑355/22, EU:C:2023:737, paragraph 30 and the case-law cited).

59The primacy and uniform application of EU law would be undermined if national courts had the power to give provisions of national law primacy in relation to EU law contravened by those provisions, even temporarily (judgment of 5 October 2023, Osteopathie Van Hauwermeiren, C‑355/22, EU:C:2023:737, paragraph 31 and the case-law cited).

60The principle of primacy accordingly obliges the national court to disapply national provisions held to be contrary to EU law having direct effect, even where the national constitutional court has previously deferred the date on which those provisions, held to be unconstitutional, are to lose their binding force (see, to that effect, judgment of 19 November 2009, Filipiak, C‑314/08, EU:C:2009:719, paragraph 85).

61The Court has also stated that the national court, having exercised the discretion conferred on it by the second paragraph of Article 267 TFEU, is bound, for the purposes of the decision to be given in the main proceedings, by the interpretation of the provisions at issue given by the Court and must, if necessary, disregard the rulings of the higher court if it considers, having regard to that interpretation, that they are not consistent with European Union law (judgment of 5 October 2010, Elchinov, C‑173/09, EU:C:2010:581, paragraph 30).

62Having regard to the foregoing considerations, the answer to the third question is that the principle of sincere cooperation as enshrined in Article 4(3) TEU and the principle of the primacy of EU law require the national court to disapply the national provisions held to be incompatible with Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, the existence of a judgment of the national constitutional court deciding to maintain the effects of those national provisions being irrelevant in that regard.

The fourth question

63By its fourth question, the referring court asks, in essence, whether the principle of sincere cooperation, as enshrined in Article 4(3) TEU, read in conjunction with Article 267 TFEU, Directive 2006/112, the principle of effectiveness and the general principles of EU law, in particular the principle of fiscal neutrality, must be interpreted as conferring on a taxable person a right to a refund of the amount of VAT collected in a Member State in breach of Article 135(1)(i) of that directive.

64In the present case, it is apparent from the order for reference that, by its fourth question, the referring court asks whether, if it were to find that Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, precludes the national legislation at issue in the main proceedings, the applicants in the main proceedings would have a right to a refund of the amount of VAT paid on the basis of that legislation.

65That question must therefore be understood as concerning the interpretation of the rules of EU law on recovery of amounts wrongly paid (see, by analogy, judgment of 6 September 2011, Lady & Kid and Others, C‑398/09, EU:C:2011:540).

66In those circumstances, and in the light of the case-law referred to in paragraphs 46 and 47 above, it is necessary to reformulate the fourth question referred for a preliminary ruling to the effect that, by that question, the referring court asks, in essence, whether the rules of EU law on recovery of amounts wrongly paid must be interpreted as meaning that they confer on a taxable person a right to a refund of the amount of VAT collected in a Member State in breach of Article 135(1)(i) of Directive 2006/112.

67It is settled case-law that the right to a refund of taxes levied by a Member State in breach of the rules of EU law is the consequence and complement of the rights conferred on individuals by provisions of EU law prohibiting such taxes, as interpreted by the Court. A Member State is, therefore, in principle required to repay charges levied in breach of EU law (judgment of 28 September 2023, Administrația Județeană a Finanțelor Publice Brașov (Transfer of the right to reimbursement), C‑508/22, EU:C:2023:715, paragraph 34 and the case-law cited).

68It appears from this that the right to the recovery of sums unduly paid helps to offset the consequences of the duty’s incompatibility with EU law by neutralising the economic burden which that duty has unduly imposed on the operator who, in the final analysis, has actually borne it (judgment of 16 May 2013, Alakor Gabonatermelő és Forgalmazó, C‑191/12, EU:C:2013:315, paragraph 24 and the case-law cited).

69However, by way of exception, such a refund may be refused where it entails unjust enrichment of the persons concerned. The protection of the rights so guaranteed by the legal order of the European Union does not require repayment of taxes, charges and duties levied in breach of EU law where it is established that the person required to pay such charges has actually passed them on to other persons (see, to that effect, judgments of 16 May 2013, Alakor Gabonatermelő és Forgalmazó, C‑191/12, EU:C:2013:315, paragraph 25, and of 21 March 2024, Dyrektor Izby Administracji Skarbowej w Bydgoszczy (Possibility of correction in the event of an incorrect rate), C‑606/22, EU:C:2024:255, paragraphs 34 and 35).

70That exception must nevertheless be interpreted restrictively, taking account in particular of the fact that passing on a charge to the consumer does not necessarily neutralise the economic effects of the tax on the taxable person (see, to that effect, judgment of 2 October 2003, Weber’s Wine World and Others, C‑147/01, EU:C:2003:533, paragraph 95).

71Accordingly, even where it is established that the burden of the charge levied though not due has been passed on to third parties, the refund of that charge to the taxable person of the amount thus passed on does not necessarily entail that taxable person’s unjust enrichment, since even where the charge is wholly incorporated in the price, the taxable person may suffer as a result of a fall in the volume of that taxable person’s sales (see, to that effect, judgments of 6 September 2011, Lady & Kid and Others, C‑398/09, EU:C:2011:540, paragraph 21, and of 21 March 2024, Dyrektor Izby Administracji Skarbowej w Bydgoszczy (Possibility of correction in the event of an incorrect rate), C‑606/22, EU:C:2024:255, paragraph 28).

72It must also be borne in mind that the existence and the measure of unjust enrichment which the refund of a charge levied though not due from the point of view of EU law would entail for a taxable person can be established only following an economic analysis which takes account of all the relevant circumstances (see, to that effect, judgments of 10 April 2008, Marks & Spencer, C‑309/06, EU:C:2008:211, paragraph 43, and of 21 March 2024, Dyrektor Izby Administracji Skarbowej w Bydgoszczy (Possibility of correction in the event of an incorrect rate), C‑606/22, EU:C:2024:255, paragraph 38).

73It follows that the answer to the fourth question is that the rules of EU law on the recovery of amounts wrongly paid must be interpreted as meaning that they confer on a taxable person a right to a refund of the amount of VAT collected in a Member State in breach of Article 135(1)(i) of Directive 2006/112, provided that that refund does not entail the unjust enrichment of that taxable person.

The sixth question

74By its sixth question, which it is appropriate to examine before the fifth question, the referring court asks, in essence, whether the obligation on Member States to ensure that the rights of individuals affected by the unlawful implementation of State aid are safeguarded, the principle of sincere cooperation and the general principles of EU law, in particular the principle of fiscal neutrality, must be interpreted as meaning that a taxable person may receive an amount equivalent to VAT paid in the form of damages, where the exemption from that tax from which other operators have benefited constitutes unlawful State aid.

75In the present case, it is apparent from the order for reference that the sixth question concerns the State aid scheme and, more specifically, the obligations of the national courts when they find that the VAT exemption from which certain operators have benefited constitutes State aid paid without having given the prior notification required by Article 108(3) TFEU.

76In those circumstances, and in the light of the case-law recalled in paragraphs 46 and 47 above, it is necessary to reformulate the sixth question referred for a preliminary ruling to the effect that, by that question, the referring court asks, in essence, whether Article 108(3) TFEU must be interpreted as meaning that, where the VAT exemption from which certain operators have benefited constitutes unlawful State aid, a taxable person who has not benefited from such an exemption may receive, in the form of damages, an amount equivalent to the VAT paid.

77In that regard, it should be noted that, it is true that it is the task of the national courts to ensure that all appropriate action is taken, in accordance with their national law, to address the consequences of an infringement of the last sentence of Article 108(3) TFEU, particularly as regards both the validity of measures giving effect to the aid and the recovery of financial support granted in disregard of that provision, the essence of their task being, consequently, to adopt the appropriate measures to cure the unlawfulness of implementation of the aid, so that the aid does not remain freely available to the beneficiary until such time as the European Commission’s decision is made (judgment of 5 March 2019, Eesti Pagar, C‑349/17, EU:C:2019:172, paragraph 89 and the case-law cited).

78In addition, a national court may be required to rule on an application for compensation for the damage caused by reason of the unlawful nature of the aid (judgment of 5 October 2006, Transalpine Ölleitung in Österreich, C‑368/04, EU:C:2006:644, paragraph 56).

79Accordingly, in fulfilling their tasks, national courts may be required to uphold claims for compensation for damage caused by the unlawful State aid to competitors of the beneficiary (judgment of 23 January 2019, Fallimento Traghetti del Mediterraneo, C‑387/17, EU:C:2019:51, paragraph 56).

80That being said, if, having regard to the rules of EU law in relation to State aid, an exemption from a tax is unlawful, that is not capable of affecting the lawfulness of the actual charging of that tax, so that a person liable to pay that tax cannot rely on the argument that the exemption from which other persons have benefited constitutes State aid in order to avoid payment of that tax (see, to that effect, judgments of 5 October 2006, Transalpine Ölleitung in Österreich, C‑368/04, EU:C:2006:644, paragraph 51, and of 3 March 2020, Vodafone Magyarország, C‑75/18, EU:C:2020:139, paragraph 24).

81If a national court were to take the view that the VAT exemption from which certain operators have benefited constitutes State aid, the grant, in the form of damages paid, to a taxable person who has paid that tax, of an amount equivalent to the VAT paid, would have the precise effect of enabling that taxable person to avoid payment of that tax.

82Consequently, the answer to the sixth question is that Article 108(3) TFEU must be interpreted as meaning that, where the VAT exemption from which certain operators have benefited constitutes unlawful State aid, a taxable person who has not benefited from such an exemption cannot receive, in the form of damages, an amount equivalent to the VAT that that taxable person paid.

The fifth question

83By its fifth question, the referring court asks, in essence, whether Article 107 TFEU must be interpreted as meaning that the exemption from VAT of the purchase of lottery tickets and the exclusion of other forms of gambling offered online from such an exemption constitute State aid incompatible with the internal market.

84It is apparent from the order for reference that that question is raised in the context of an action brought by a taxable person seeking to recover, in the form of damages, the equivalent of the VAT which that taxable person has paid. In addition, it is not apparent from that decision that that question has another purpose.

85It follows from the answer to the sixth question that, where the VAT exemption from which certain operators have benefited constitutes State aid, a taxable person who has not benefited from such an exemption cannot receive, in the form of damages, an amount equivalent to the VAT that that taxable person paid.

86Therefore, in view of the answer given to the sixth question, there is no need to answer the fifth question.

Costs

87Since 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.

Operative part

On those grounds, the Court (First Chamber) hereby rules:

Article 135(1)(i) of Council Directive 2006/112/EC of 28 November 2006 on the common system of value added tax, read in conjunction with the principle of fiscal neutrality,

must be interpreted as not precluding national legislation which differentiates between, on the one hand, the purchase of lottery tickets online and, on the other hand, participation in other forms of gambling offered online, by excluding the latter from the value added tax exemption applicable to the former, provided that the objective differences between those two categories of gambling are liable to have a considerable influence on the decision of the average consumer to use one or other of those categories of games.

The principle of sincere cooperation as enshrined in Article 4(3) TEU and the principle of the primacy of EU law require the national court to disapply the national provisions held to be incompatible with Article 135(1)(i) of Directive 2006/112, read in conjunction with the principle of fiscal neutrality, the existence of a judgment of the national constitutional court deciding to maintain the effects of those national provisions being irrelevant in that regard.

The rules of EU law on the recovery of amounts wrongly paid must be interpreted as meaning that they confer on a taxable person a right to a refund of the amount of the value added tax collected in a Member State in breach of Article 135(1)(i) of Directive 2006/112, provided that that refund does not entail the unjust enrichment of that taxable person.

Article 108(3) TFEU must be interpreted as meaning that, where the value added tax (VAT) exemption from which certain operators have benefited constitutes unlawful State aid, a taxable person who has not benefited from such an exemption cannot receive, in the form of damages, an amount equivalent to the VAT that that taxable person paid.

OPINION OF ADVOCATE GENERAL

KOKOTT

delivered on 25 April 2024 ¹

(Reference for a preliminary ruling – Tax law – Value added tax – Directive 2006/112/EC – Article 135(1)(i) – Exemption of gambling – Direct effect of the exemption – Differentiation between online gambling and analogue gambling – Differentiation between various kinds of online gambling (lotteries and other forms of online gambling) – Inadmissibility of questions referred for a preliminary ruling – Temporary maintenance in force of national law without prior reference for a preliminary ruling – VAT exemption as aid)

I. Introduction

‘In gambling the many must lose in order that the few may win.’ (George Bernard Shaw, Anglo-Irish playwright and politician, 1856 to 1950).

1Although these and other dangers of gambling are generally recognised, Article 135(1)(i) of Directive 2006/112/EC on the common system of value added tax (‘the VAT Directive’) ² has always exempted betting, lotteries and other forms of gambling. At first sight, the European Union appears to seek to promote gambling in terms of VAT. However, that exemption only applies ‘subject to the conditions and limitations laid down by each Member State’.

2Belgium has opted no longer to exempt online gambling (except online lotteries) from VAT since 1 July 2016. Other forms of gambling (including lotteries), however, remain exempt from VAT. Online gambling providers in Belgium consider this selective exemption in this case and that of Chaudfontaine Loisirs SA (C‑73/23) ³ to be an infringement of the principle of neutrality. Here, it is also argued that the exemption of other gambling providers constitutes an unlawful State aid. In the end, a VAT exemption for online gambling is to be derived directly from EU law. This can only be successful in so far as the VAT Directive has direct effect in that respect, that is to say if that exemption already derives from it.

3Although the Court has dealt with the different taxation of various types of gambling in VAT law on several occasions in the past, ⁴ recent case-law gives cause to consider in depth the direct effect of Article 135(1)(i) of the VAT Directive in such a situation (selective exemption of individual types of gambling). At the same time, the Court has the opportunity to clarify whether and to what extent the principle of neutrality precludes a selective exemption of individual types of gambling.

II. Legal framework

A. European Union law

4Article 107(1) of the Treaty on the Functioning of the European Union (‘TFEU’) contains a prohibition on aid:

‘1. Save as otherwise provided in the Treaties, any aid granted by a Member State or through State resources in any form whatsoever which distorts or threatens to distort competition by favouring certain undertakings or the production of certain goods shall, in so far as it affects trade between Member States, be incompatible with the internal market.’

5Article 135(1)(i) of the VAT Directive governs the exemption of gambling from tax and is worded as follows:

‘1. Member States shall exempt the following transactions:

…

betting, lotteries and other forms of gambling, subject to the conditions and limitations laid down by each Member State.’

B. Belgian law

6Article 8 of the loi spéciale sur la Cour constitutionnelle du 6 janvier 1989 (Special Law on the Constitutional Court of 6 January 1989) stipulates:

‘If the action is well founded, the Constitutional Court shall entirely or partially annul the statute, decree or rule referred to in Article 134 of the Constitution against which the action was instituted. …

Where the Court so deems necessary, it shall, by way of a general provision, specify which effects of the annulled provisions are to be considered permanent or provisionally maintained for the period determined by the Court.’

7Article 9 of the special law provides:

Ԥ 1. Annulment judgments delivered by the Constitutional Court shall have the force of res judicata as from their publication in the Moniteur Belge.

§ 2. The judgments delivered by the Constitutional Court whereby actions for annulment are dismissed shall be binding on the courts with respect to the points of law settled by those judgments.’

8Article 44(3)(13) of the code de la taxe sur la valeur ajoutée (Value Added Tax Code) (as in force from 1 July 2016 to 21 May 2018) states:

‘The following shall also be exempt from the tax: …

13.

(a) lotteries;

(b) other forms of gambling, with the exception of those provided electronically as referred to in Article 18(1)(2)(16); …’

III. Facts and preliminary ruling procedure

9Twenty-seven companies governed by Belgian law, including Casino de Spa SA, which together constitute the ‘VAT unit’ GAMING ARDENT (‘the applicant’), and which are thus regarded as a single taxable person for VAT purposes, operate online games.

10Originally, transactions relating to gambling were exempt from VAT in Belgium. Articles 29 to 34 of the Programme Law of 1 July 2016 annulled that exemption. As a result, those transactions became taxable, while ‘conventional’ types of gambling and all lotteries (online and analogue) remained exempt from tax.

11However, the Cour constitutionnelle (Constitutional Court, Belgium) annulled the provisions in question of the Programme Law of 1 July 2016 by decision of 22 March 2018 on the grounds that it infringes the rules on the division of powers between the Federal State and the Regions (Article 177 of the Belgian Constitution). It stated that the taxes already paid for the period from 1 July 2016 to 21 May 2018 would nevertheless be maintained in view of the budgetary and administrative difficulties which would arise from their reimbursement.

12The applicant nevertheless applied for reimbursement of an amount of EUR 15 581 402.06, which it had paid as VAT on online games carried out from 1 July 2016 to 21 May 2018, after deducting the corresponding input VAT.

13In a report of 5 December 2019, the administration rejected that application on the ground that the conditions for reimbursement were not met. The applicant then brought an action before the referring court.

14The applicant considers that maintaining the effects of the annulled law is contrary to the principle of VAT neutrality, in that other forms of gambling are exempt, as well as contrary to other rules of EU law, including the prohibition of State aid. In the alternative, it claims that the Belgian State is liable on account of a fault on the part of the Cour constitutionnelle (Constitutional Court) in that temporarily maintaining the effects of the annulled provisions infringes Article 1 of the First Additional Protocol to the European Convention for the Protection of Human Rights and Fundamental Freedoms guaranteeing the protection of property. The defendant Belgian State, by contrast, considers that the claim is unfounded and that it cannot be ordered to refund the VAT.

15The tribunal de première instance de Liège (Court of First Instance, Liège, Belgium) seised of the action stayed the proceedings and referred the following six questions to the Court of Justice for a preliminary ruling under Article 267 TFEU:

Must Article 135(1)(i) of [the VAT Directive] be interpreted as precluding a Member State from using different treatment for online lotteries offered by Loterie Nationale [(the Belgian national lottery)], a public establishment, which are exempt from value added tax, and other online games of chance offered by private operators, which are subject to value added tax, assuming that they are similar supplies?

In answering the previous question, in order to determine whether there are two similar categories which are in competition with each other and which require the same treatment for the purposes of value added tax, or whether there are separate categories which allow for different treatment, must the national court consider only whether or not the two forms of games are in competition with each other from the point of view of the average consumer, in the sense that services are similar where they have similar characteristics and meet the same needs from the point of view of consumers, the test being whether their use is comparable, and where the differences between them do not have a significant influence on the decision of the average consumer to use one or the other of those services (alternative criterion), or must it take into account other criteria such as the existence of a discretionary power on the part of the Member State to exempt certain categories of games from VAT and to subject others to it, the fact that lotteries belong to a distinct category of games, referred to in Article 135(1)(i) of [the VAT Directive], the different legal frameworks which apply to Loterie Nationale and to other games of chance, the different supervisory authorities or the societal and gambler protection objectives pursued by the legislation applicable to Loterie Nationale?

Must the principle of sincere cooperation set out in Article 4(3) TEU, read in conjunction with Article 267 TFEU, the provisions of [the VAT Directive] and, where applicable, the principle of effectiveness, be interpreted as meaning that they allow the constitutional court of a Member State to maintain – on its own initiative and without a reference for a preliminary ruling under Article 267 TFEU – on the basis of a provision of national law – in this case Article 8 of the loi spéciale du 6 janvier 1989 sur la Cour constitutionnelle (Special Law of 6 January 1989 on the Constitutional Court) – the retrospective effect of national provisions on value added tax which were found to be contrary to the national Constitution and were annulled on that ground and whose non-conformity with EU law was also relied on in support of the action for annulment before the national court, without, however, that complaint having been examined by the latter, on the general ground of “budgetary and administrative difficulties which reimbursement of taxes already paid would cause”, thus completely depriving taxable persons subject to VAT of the right to reimbursement of the VAT collected in breach of EU law?

If the answer to the preceding question is in the negative, do the same provisions and principles, interpreted, in particular, in the light of the judgment of 10 April 2008, Marks & Spencer [(C‑309/06, EU:C:2008:211)] under which the general principles of Community law, including that of fiscal neutrality, give a trader who has made supplies a right to recover the sums mistakenly claimed in respect of them (judgment of 10 April 2008, Marks & Spencer, C‑309/06[, EU:C:2008:211)]), require the Member State concerned to reimburse to the taxable persons the VAT collected in breach of EU law where, as in the present case, it subsequently follows from a judgment of the Court of Justice, in response to questions referred for a preliminary ruling, that the annulled national provisions are not in conformity with [the VAT Directive] and that the decision of the constitutional court to maintain the retrospective effect of the provisions annulled by it is not in conformity with EU law?

Does the different treatment introduced by Articles 29, 30, 31, 32, 33 and 34 of the loi-programme du 1er juillet 2016 (Programme Law of 1 July 2016), which were annulled by Constitutional Court judgment No 34/2018 of 22 March 2018, but the effects of which were maintained after that date in respect of the taxes already paid for the period from 1 July 2016 to 21 May 201[8], between lotteries, whether terrestrial or online, and other online games and forms of betting create a selective advantage in favour of the operators of those lotteries and thus aid granted by the Belgian State or through Belgian State resources which distorts or threatens to distort competition by favouring certain undertakings, which is incompatible with the internal market within the meaning of Article 107 TFEU?

If the answer to the preceding question is in the affirmative, does the obligation on the Member States to safeguard the rights of individuals affected by the unlawful implementation of the aid in question, in accordance with, inter alia, the judgment of 5 October 2006, Transalpine Ölleitung in Österreich [(C‑368/04, EU:C:2006:644)] the principle of sincere cooperation and the general principles of Community law, including that of fiscal neutrality, which give a trader who has made supplies a right to recover the sums mistakenly charged in respect of them (judgment of 10 April 2008, Marks & Spencer (C‑309/06[, EU:C:2008:211]), allow taxable persons who have been charged VAT on the basis of unlawful State aid to recover the equivalent of the tax paid in the form of damages for the loss suffered?’

16The applicant, the Kingdom of Belgium, the Federal Republic of Germany, the Czech Republic and the European Commission submitted written observations in the proceedings before the Court. In accordance with Article 76(2) of the Rules of Procedure of the Court of Justice, the Court did not consider it necessary to hold a hearing.

IV. Legal assessment

17The six questions can essentially be broken down into three sets.

18Since the applicant in the main proceedings is challenging the levying of VAT on its services under national law, Questions 1 and 2 relate to whether those services are exempt from VAT under Article 135(1)(i) of the VAT Directive and the applicant is to be reimbursed the tax paid in breach of EU law despite the maintenance in force of national law to the contrary. This requires that an exemption for online gambling arises directly from the VAT Directive on which the applicant can rely (B).

19Questions 3 and 4, on the other hand, relate to whether the Belgian Constitutional Court could nevertheless order the continued application of national law without a prior reference for a preliminary ruling due to a possible infringement of EU law, which is why the tax arose under national law after all, and whether this precludes a claim for repayment of the tax possibly paid in breach of EU law. This already raises the question of the admissibility of these two questions referred (A).

20Questions 5 and 6, by contrast, concern whether different VAT treatment of lotteries (exempt) and other online games and online betting (taxed) also constitutes prohibited State aid (C).

A. Admissibility of Questions 3 and 4

21Questions 3 and 4 are admissible in preliminary ruling proceedings only if the answer to them is necessary and relevant in order to give judgment in the main proceedings.

22In principle, it is solely for the national court before which the dispute has been brought to determine both the need for a preliminary ruling in order to enable it to deliver judgment and the relevance of the questions which it submits to the Court. Questions concerning the interpretation of a rule of EU law enjoy a presumption of relevance. ⁵ The Court may refuse to rule on a question only where it is quite obvious that the interpretation of EU law that is 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. ⁶

23Even on the basis of the abovementioned presumption, Questions 3 and 4 are inadmissible in this case. The main proceedings concern the reimbursement of a tax which may have been paid in breach of EU law (or more precisely, in breach of the directive). The national statute was, although it had to be annulled for reasons of national law, also declared by the competent national court to be maintained in force for a certain period of time on reasons of national law (the order that it be temporarily maintained in force).

24National law thus requires taxation that may infringe the VAT Directive. Whether the applicant remains obliged to pay the VAT already paid for the period from 1 July 2016 to 21 May 2018 therefore results solely from the interpretation of the VAT Directive and thus from the answer to Questions 1 and 2. The remaining content of Questions 3 and 4 is thus reduced to the question whether the Cour constitutionnelle (Constitutional Court) could or even should have referred the matter to the Court of Justice before ordering that the national tax be maintained and whether, if that obligation is affirmed, a claim for refund follows therefrom. However, a potential obligation on the Cour constitutionnelle (Constitutional Court) to make a reference is irrelevant to the existence or otherwise of a payment obligation on the part of the applicant.

25Furthermore, it is not clear why an infringement of Article 267 TFEU by one court, namely the Constitutional Court, should have a bearing on the decision of another court, which referred the decisive questions of EU law to the Court of Justice for a preliminary ruling. The dissatisfaction with the conduct of the Belgian Constitutional Court in not making a reference for a preliminary ruling and the interpretation of Article 267 TFEU that is sought consequently bears no relation to the dispute in the main proceedings. Questions 3 and 4 are therefore inadmissible.

26Lastly, the referring court does not inform the Court of Justice of what the Cour constitutionnelle (Constitutional Court) can and may actually examine. If its national power of review is limited, for example, to compliance with the national rules on competence, a reference for a preliminary ruling can hardly be considered. Therefore, the Court of Justice does not have the necessary information to be able to examine an infringement of Article 267 TFEU. For this reason too, Questions 3 and 4 are inadmissible.

B. The exemption of online gambling pursuant to the VAT Directive (Questions 1 and 2)

27In the main proceedings, the applicant objects to the taxation of its online gambling services under national law (maintained in force). This appears to be unambiguous and cannot be interpreted in conformity with EU law. Therefore, the interpretation of Article 135(1)(i) of the VAT Directive is only relevant if that article has direct effect (1). Essentially, the applicant takes the view that its services should be treated in precisely the same way as other exempt gambling services. That could possibly also result from the principle of neutrality of VAT (2).

1. Direct effect of the exemption?

28According to settled case-law, whenever the provisions of a directive appear, so far as their subject matter is concerned, to be unconditional and sufficiently precise, they may be relied upon before the national courts by individuals against the Member State where the Member State has failed to implement the directive in domestic law within the period prescribed or where it has failed to implement the directive correctly. ⁷

29A provision of EU law is unconditional where it sets forth an obligation which is not qualified by any condition, or subject, in its implementation or effects, to the taking of any measure either by the institutions of the European Union or by the Member States. ⁸ On the other hand, a provision is conditional if it involves the application of national provisions determining the actual scope of the conditions under which EU law is applicable. ⁹ It is sufficiently precise where it sets out an obligation in unequivocal terms. ¹⁰

30In the light of this settled case-law, Article 135(1)(i) of the VAT Directive is neither unconditional nor sufficiently precise. It provides that gambling is to be exempted ‘subject to the conditions and limitations laid down by each Member State’. It does not make clear which forms of gambling specifically are to be exempted and therefore an obligation is not imposed on the Member State in unequivocal terms. On the contrary, it follows from the wording that only certain forms of gambling (chosen by the Member States) can be exempted.

31Nor is that obligation unconditional because, according to the clear wording of Article 135(1)(i) of the VAT Directive, it is qualified by ‘the conditions and limitations laid down by each Member State’. Consequently, the exemption of gambling requires, in its implementation or effects, the taking of a measure by the Member States.

32It is probably for that reason that the Court ¹¹ expressly ruled in 2010 that ‘Article 135(1)(i) of [the VAT Directive] must be interpreted as meaning that the exercise of the discretionary power of the Member States to fix conditions and limitations on the exemption from value added tax provided for by that provision allows those States to exempt from that tax only certain forms of gambling’. It subsequently confirmed that interpretation on two occasions. ¹²

33However, if – following the Court’s interpretation – Article 135(1)(i) of the VAT Directive allows Member States to exempt only certain forms of gambling, the same applies in this case as the Court of Justice has ruled on other tax exemptions. In so far as the Member States only had to exempt certain services (as in Article 132(1)(n) and (m) of the VAT Directive), those provisions have no direct effect. ¹³

34The expression ‘certain forms of gambling’ in the Court’s decision ¹⁴ indicates that that provision does not impose an obligation on Member States to make a general exemption for ‘all’ services that constitute gambling. ¹⁵ To interpret Article 135(1)(i) of the VAT Directive as meaning that, notwithstanding the use of the word ‘certain’, Member States are obliged to exempt ‘all’ forms of gambling would be liable to extend the material scope of the exemption. That would also be contrary to the Court’s case-law stating that the exemptions in the VAT directive are to be interpreted strictly. ¹⁶

35The very fact that Article 135(1)(i) of the VAT Directive allows Member States to exempt only ‘certain’ ¹⁷ forms of gambling militates against the direct effect of Article 135(1)(i) of the VAT Directive. ¹⁸

36The only (earlier) decision of the Court of Justice which, by contrast, attributed direct effect to the predecessor provision in Article 13(B)(f) of the Sixth [Council] Directive 77/388 [of 17 May 1977 on the harmonisation of the laws of the Member States relating to turnover taxes – Common system of value added tax: uniform basis of assessment (OJ 1977 L 145, p. 1)] in order to prevent the application of rules of national law which are incompatible with that provision, ¹⁹ has, in my view, been superseded by the more recent case-law on the direct effect of VAT exemptions ²⁰ and VAT options ²¹ and by the decision of the Court of Justice from 2010. ²²

37This is also convincing in terms of substance. That is because the exemption of gambling in Article 135(1)(i) of the VAT Directive is not linked to any particular evaluation under EU law. According to the Court, that exemption is merely based on practical considerations, in that gambling transactions do not lend themselves easily to the application of VAT. Unlike in the case of certain public interest services supplied in the social sector, there is no desire here to afford those activities more advantageous VAT treatment. ²³ It is more likely that that exemption reflects a compromise between the then six Member States, some of which already had special gambling laws and therefore taxed individual forms of gambling. By the exemption subject to the conditions and limitations of the Member States, they were able to retain their gambling laws and avoid double levying of VAT.

38In any case, it is not possible to see any reason why such an exemption should have direct effect for purely technical reasons (impractical levying or avoidance of double taxation) under the conditions and within the limitations of the individual Member States. There is therefore no need for a particularly extensive assumption of a direct effect of that exemption. The fact therefore remains that the exemption has no direct effect.

39However, if the applicant cannot in any event rely directly on the exemption laid down in Article 135(1)(i) of the VAT Directive in this case, there is no need to answer Questions 1 and 2. It is then for the Commission to bring infringement proceedings against Belgium if it believes that the taxation of the applicant (and other online gambling operators) infringes the VAT Directive. However, no such concerns are evident from the Commission’s observations.

2. Infringement of the principle of neutrality?

40The principle of fiscal neutrality is of no assistance to the applicant in this regard either. A Member State must also comply with the principle of fiscal neutrality when exercising its options or discretion. ²⁴ First, this cannot lead to the direct effect of an insufficiently precise or conditionally worded provision of a directive. Secondly, that principle ‘merely’ precludes that similar goods or services which are in competition with each other are treated differently for VAT purposes. ²⁵

41Goods or services are similar where they have similar characteristics and meet the same needs from the point of view of consumers, the test being whether their use is comparable. In addition, the differences between them must not have a significant influence on the decision of the average consumer to use one or the other of those goods, ²⁶ and those supplies can therefore, from the point of view of the average consumer, be exchanged one for the other. ²⁷ The assessment as to whether goods or services are similar from the point of view of a consumer entails by definition a degree of discretion.

42In connection with the adoption of tax measures, the Court recognises that the EU legislator is called upon to make political, economic and social choices, and to rank divergent interests or to undertake complex assessments. As a result, it must be granted broad discretion, so that judicial review must be limited to manifest errors. ²⁸ In particular, the Court cannot substitute its own assessment for that of the EU legislator. ²⁹

43In the light of the Court’s most recent case-law, the same applies in relation to the review of the discretion of national legislators. The Court thus increasingly points out the fact that the European Union is composed of States which respect and share the values referred to in Article 2 TEU. ³⁰ The values referred to in Article 2 TEU, on which the European Union is founded, include in particular the principle of democracy. According to that principle, it is the democratically legitimised legislator that is primarily responsible for discharging the discretion to make legislative decisions.

44Consequently, where EU law grants such discretion to a Member State, it is the elected parliament of that Member State that is responsible for exercising it. The powers of other bodies to review that parliamentary decision-making discretion are therefore, by definition, limited. They cannot substitute their own view as to the similarity of goods or services for that of the body democratically legitimised to form it. This applies to national courts just as much as to the courts of the European Union.

45On that basis, both the Court of Justice and a court of a Member State such as the referring court may, as a general rule, find the principle of neutrality to have been infringed by the democratically legitimised legislator only if it has clearly exceeded its decision-making discretion.

46This is the case, however, only if, from the point of view of the average consumer, the goods or services taxed at different rates are all but identical and could therefore readily be substituted for each other, ³¹ as the Commission also submits. It is only then that there is a distortion of competition between the providers of those goods or services which is no longer compatible with the principle of neutrality.

47For that reason, the Court has thus far been generally reluctant to find an infringement of the principle of neutrality, where, for example the Member States apply a reduced rate of tax, or an exemption from tax, only to fresh pastry goods and cakes (but not to those which exceed a certain best-before date ³²), only to mobile fairground entertainers (but not to stationary amusement parks ³³), not to all medicinal products (but only to certain ones, depending, inter alia, on how they are used ³⁴), only to taxis (but not to all forms of passenger transport by car ³⁵), or only to printed books (but not to books on other physical media ³⁶).

48In the light of this limited power of review of the courts, there is no manifest exceeding of decision-making discretion in this case. The differently taxed services (online gambling or non-lottery online gambling, on the one hand, and ‘analogue’ gambling or online lotteries, on the other) differ – contrary to the view taken by the applicant – from the point of view of an average consumer in several respects.

49For example, online gambling differs from ‘analogue’ gambling in terms of location (anytime and anywhere versus specific locations); the effort required to start such gambling (no effort, as possible anytime and anywhere via smartphone, versus physical movement to a specific location required); the lack of ‘social control’ of gambling in private which is possible at any time; the potential for addiction or the danger of gambling that is available and easily accessible at any time, and also the way in which the gambling is carried out (click on the computer versus physical action on a slot machine or even interaction with a person (for example, a croupier) on site). A visit to an ‘analogue’ casino can be described more as an ‘event’, whilst a ‘visit’ to a website (‘online casino’) can be described more as ‘gambling on the internet’.

50Having regard solely to the content of the service (in this case the satisfaction of a gaming need) is therefore of no assistance. Instead, the external factual and legal context must also be included in the point of view of an average consumer. ³⁷ The same applies in relation to any objectives that a parliamentary body may be pursuing by differentiation. The principle of neutrality of VAT does not prohibit objectively justified differentiations.

51The fact that the medium (online versus ‘analogue’) is a significant criterion for differentiation from the point of view of the EU legislator is, moreover, demonstrated by the provisions of the VAT Directive, some of which also differentiate according to whether a service is provided electronically (see, inter alia, the place of taxation (special provision in Article 58 of the VAT Directive) or the tax rate (Article 98(3) of the VAT Directive excludes certain reduced tax rates for services which are provided electronically)). All of this would be unnecessary if electronic and ‘analogue’ transactions were readily interchangeable.

52Consequently, for there to be an infringement of the principle of neutrality it is not sufficient for different types of gambling to satisfy a comparable gambling need (or a comparable gambling addiction). Nor is it sufficient that one or the other consumer may switch from one type of gambling to another, so that a certain degree of competition between the different providers cannot be ruled out. The decisive factor is rather whether the legislator considers that the two services can, from the point of view of the average consumer, (obviously) be exchanged one for the other.

53As a result of the circumstances of the use of the services and the associated different risks of gambling, ‘online’ and ‘analogue’ gambling can therefore also be taxed differently – as the Commission and Belgium submit.

54Nor can the distinction in Belgium between online lotteries and other forms of online gambling be called into question. Lotteries are a special type of gambling that is usually organised according to a specific programme in return for a fixed stake with the prospect of winning certain cash or non-cash prizes. The outcome is based on chance and is usually announced publicly. In that type of gambling – as the Commission rightly points out – the activity is limited to the purchase of a lottery ticket and in that respect differs from other forms of online gambling which are based on repeated activities of the player, who immediately learns of his or her good fortune (or more often bad fortune) and reacts spontaneously. As Belgium submits, the gaming element is missing in that case. There are also differences in the minimum and maximum permitted stakes, prizes and the chances of winning. ³⁸

55Furthermore, the histories of lotteries and certain (historical) tax laws of the Member States show a traditional separation between lotteries and other kinds of gambling. ³⁹ This indicates that for an average consumer, a lottery has probably always been something different from gambling in a casino or on a slot machine. It can therefore hardly be claimed that online lotteries and other forms of online gambling can, from the point of view of the average consumer, be exchanged one for the other. An infringement of the principle of neutrality is also not apparent in this regard.

3. Interim conclusion

56Article 135(1)(i) of the VAT Directive has no direct effect. Even if Article 135(1)(i) of the VAT Directive did have direct effect, Belgium’s differentiation between gambling which is provided electronically and gambling which is not provided electronically would not constitute an infringement of the principle of neutrality of VAT. The same applies in relation to the differentiation between gambling which is provided electronically and lotteries which are carried out electronically. In the absence of an infringement of EU law, EU law therefore does not require that the VAT owed under national law must be reimbursed to the applicant.

C. Prohibited aid on account of different VAT treatment (Questions 5 and 6)

57In so far as the referring court asks as to the existence of aid, those questions are also inadmissible. According to settled case-law of the Court, those liable to pay a tax cannot rely on the argument that the exemption enjoyed by other businesses constitutes State aid in order to avoid payment of that tax. ⁴⁰

58Only if the tax is used to favour other businesses is it necessary to examine whether the revenue from the tax is used in a manner compatible with the rules on State aid. ⁴¹ That is not the situation here, however. In the present case, the burden is imposed on the applicant in the main proceedings by a general tax (VAT), which is paid into the general public budget and does not therefore specifically favour any third party. Accordingly, in the present case the applicant is challenging only a tax notice addressed to it, which it considers to be unlawful because other taxable persons are not taxed to the same extent. This cannot succeed under the rules on State aid.

59In principle, unlawfully granted aid must be recovered. ⁴² However, not taxing the applicant would not amount to recovery, but would merely extend the State aid to the applicant in this case and thus not eliminate the distortion of competition, but intensify it. Therefore, in proceedings relating solely to a business’ own tax liability the question of State aid to a third party is not relevant to the decision and is not therefore admissible, as the Court has already ruled on several occasions. ⁴³

60Furthermore, no prohibited aid within the meaning of Article 107(1) TFEU is evident from a substantive point of view. According to the settled case-law of the Court, for that to be the case there must be a State measure which confers a selective advantage on the beneficiary. ⁴⁴

61If, as stated above, Article 135(1)(i) of the VAT Directive must be interpreted as meaning that the exercise of the power of the Member States to fix conditions and limitations on the VAT exemption provided for by that provision allows those States to exempt from VAT only certain forms of gambling, then that (selective) exemption is already laid down in EU law. However, correct implementation of EU law (see, in this respect, point 40 et seq. above) can hardly be regarded as a State measure by Belgium under the rules on State aid. Rather, it is a matter of EU law.

62Moreover, there is also no advantage of an undertaking, as Germany rightly points out. In VAT law, exemptions only benefit the recipient of the supplies because it is settled case-law of the Court that VAT is an indirect tax on consumption which is to be borne by the final consumer. ⁴⁵ In that regard, the taxable undertaking acts only as ‘tax collectors for the State and in the interest of the public exchequer’. ⁴⁶ From a material point of view, VAT is therefore intended to tax not the taxable undertaking but the financial capacity of consumers as reflected in their expenditure of assets to obtain a consumable benefit. ⁴⁷ However, if the liability to VAT of a service is intended to burden the consumer and not the provider, then a VAT exemption should only exempt the consumer and not the provider. The VAT exemption for gambling services is therefore an advantage of the consumer and not the provider.

63Furthermore, there is a selective advantage only if a national measure is such as to favour ‘certain undertakings or the production of certain goods’ over others, which, in the light of the objective pursued by that regime, are in a comparable factual and legal situation and which are accordingly subject to different treatment that can, in essence, be classified as ‘discriminatory’. ⁴⁸

64That requires a derogation from ‘normal taxation’, which is not justified. Both are lacking here. According to Article 135(1)(i) of the VAT Directive, normal taxation is the exemption of gambling, which is precisely the case here as regards ‘analogue’ gambling and all lotteries. Furthermore, the differentiation under VAT law between online gambling and other forms of gambling and also between online lotteries and online gambling is – as stated above (point 40 et seq.) – objectively justified and therefore not discriminatory. The rules on State aid also do not prohibit objectively justified differentiations in a general law. Consequently, the element of selectivity is also lacking.

V. Conclusion

65I therefore propose that the questions referred by the tribunal de première instance de Liège (Court of First Instance, Liège, Belgium) be answered as follows:

Article 135(1)(i) of the VAT Directive has no direct effect. It is neither unconditional nor sufficiently precise.

The principle of neutrality of VAT does not preclude a differentiation between gambling which is provided electronically and gambling which is not provided electronically. Instead, there are objective reasons for this and for the differentiation between gambling which is provided electronically and lotteries which are organised electronically.

In proceedings relating solely to a business’ own tax liability the question of State aid to a third party is inadmissible. In principle, those liable to pay a tax cannot rely on the argument that the exemption enjoyed by other businesses constitutes State aid in order to avoid payment of that tax.
