1
This request for a preliminary ruling concerns the interpretation of the third paragraph of Article 267 TFEU, the principle of fiscal neutrality 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).
2
The request has been made in proceedings between Chaudfontaine Loisirs SA and the État belge (SPF Finances) (Federal Public Finance Service, Belgium) (‘the Belgian tax authority’), 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
3
Article 135(1)(i) of Directive 2006/112 provides:
‘Member States shall exempt the following transactions:
…
(i)
betting, lotteries and other forms of gambling, subject to the conditions and limitations laid down by each Member State.’
Belgian law
4
Article 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”:
(a)
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;
(b)
games, under whatever name, which offer participants in a competition of any kind the chance to win prizes or awards in cash 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.’
5
Article 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°
(a)
lotteries;
(b)
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
6
Chaudfontaine Loisirs offers online gambling.
7
That 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.
8
Those 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 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.
9
In 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.
10
Following those judgments, in the part of its VAT return for November 2019, relating to the VAT adjustments in its favour, Chaudfontaine Loisirs entered an amount of EUR 640 478.82, 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 630 240.56.
11
It reiterated that request in a letter of 16 December 2019, in which it stated that the Court had held, in its judgment of 27 June 2019, Belgisch Syndicaat van Chiropraxie and Others (C‑597/17, EU:C:2019:544), that a national court may not make use of a national provision empowering it to maintain certain effects of an annulled measure.
12
By decision of 1 December 2020, the Belgian tax authority rejected that request and stated that that judgment concerned a situation in which the annulled national provisions had been found to be contrary to Directive 2006/112, whereas, in its judgment of 22 March 2018, the Cour constitutionnelle (Constitutional Court) had annulled the national provisions at issue in the main proceedings because of an infringement of the rules allocating powers laid down by Belgian law.
13
On 7 December 2020, a statement of adjustment was drawn up by the Belgian tax authority, in which they stated that Chaudfontaine Loisirs owed an amount of EUR 640 478.82 in respect of VAT, an amount of EUR 64 047.88 in respect of fines and late interest payments at a rate of 0.8% per month on the amount of VAT payable from 21 December 2019.
14
On 13 April 2021, Chaudfontaine Loisirs brought an action before the tribunal de première instance de Liège (Court of First Instance, Liège, Belgium), which is the referring court, against that decision and that statement of adjustment. 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.
15
In 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:
‘(1)
Do Article 135(1)(i) of [Directive 2006/112] and the principle of fiscal neutrality permit a Member State to exclude from the benefit of the exemption contained in that provision only gambling which is provided electronically while gambling which is not provided electronically remains exempt from VAT?
(2)
Do Article 135(1)(i) of [Directive 2006/112] and the principle of fiscal neutrality permit a Member State to exclude from the benefit of the exemption contained in that provision only gambling which is provided electronically to the exclusion of lotteries which remain exempt from VAT whether or not they are provided electronically?
(3)
Does the third paragraph of Article 267 of the [TFEU] permit a higher court to decide to maintain the effects of a provision of national law which it annuls because of an infringement of national law without ruling on the infringement of EU law which was also raised before it, and, therefore, without referring for a preliminary ruling the question of the compatibility of that provision of national law with EU law or asking the Court about the circumstances in which it could decide to maintain the effects of that provision in spite of its incompatibility with EU law?
(4)
If the answer to one of the previous questions is in the negative, could the [Cour constitutionelle (Constitutional Court)] maintain the past effects of the provisions which it annulled because of their incompatibility with national rules on the division of powers when those provisions were also incompatible with [Directive 2006/112], in order to prevent budgetary and administrative difficulties from arising from reimbursement of taxes already paid?
(5)
If the answer to the previous question is in the negative, can the taxable person be reimbursed the VAT which it has paid on the actual gross margin on the gaming and betting which it operates on the basis of provisions incompatible with [Directive 2006/112] and the principle of fiscal neutrality?’
The application to reopen the oral part of the procedure
16
After the Advocate General delivered her Opinion at the sitting on 25 April 2024, Chaudfontaine Loisirs, by letter received at the Court Registry on 5 June 2024, requested the Court to order the reopening of the oral part of the procedure.
17
In support of that request, Chaudfontaine Loisirs submits 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 it has therefore been unable to submit its observations. Chaudfontaine Loisirs also disagrees with the Advocate General’s Opinion on that point.
18
In 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.
19
It 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).
20
Furthermore, 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).
21
In the present case, the Court considers, after hearing the Advocate General, that it has all the information necessary to give a ruling.
22
In particular, in the light of the case-law referred to in paragraph 20 above, it should be noted that, contrary to Chaudfontaine Loisirs’ submissions in support of its request for the reopening of the oral part of the procedure, in so far as the fifth 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 Chaudfontaine Loisirs had the opportunity to put forward its point of view in that regard.
23
Consequently, 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
24
By 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 and participation in other forms of gambling offered offline and, on the other hand, participation in forms of gambling other than lotteries offered online, by excluding the latter from the VAT exemption applicable to the former.
25
According 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.
26
It 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).
27
In 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).
28
However, 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).
29
According 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).
30
In 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).
31
Two 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).
32
In 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).
33
In 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).
34
Thus, 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).
35
Moreover, 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 or gambling 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).
36
However, 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).
37
In the present case, it is apparent from the order for reference that the legislation at issue establishes a twofold difference in treatment. First, that legislation distinguishes lotteries from other forms of gambling, by exempting from VAT any purchase of lottery tickets, whether online or offline. Second, that legislation establishes a difference in treatment between games of chance and gambling other than online and offline lotteries, by excluding online gambling from the exemption applicable to offline games.
38
Although it is for the referring court alone to assess, in the light of the considerations set out in paragraphs 29 to 37 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).
39
In 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, both between lotteries and other forms of gambling and between forms of gambling other than lotteries offered online and offline.
40
As regards, more specifically, in the first place, the examination of the similarity of lotteries and other forms of gambling, 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.
41
Lotteries, 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.
42
Such 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.
43
As regards, in the second place, the examination of whether participation in forms of gambling other than lotteries offered online and offline is similar, account must be taken, in particular, of the contextual factors surrounding those games.
44
Differences relating to the geographical and temporal accessibility of games, the possibilities of anonymity and the physical or virtual nature of the interactions between players or between players and the organisers of games 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.
45
In the light of the considerations set out in paragraphs 29 to 44 above, it seems, at first glance, that the services referred to in paragraph 37 above are not similar, which means that the differences in treatment such as those at issue in the main proceedings are 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.
46
Consequently, 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 and participation in other forms of gambling offered offline and, on the other hand, participation in forms of gambling other than lotteries offered online, by excluding the latter from the VAT exemption applicable to the former, provided that the objective differences between those 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 and fourth questions
47
By its third and fourth questions, which it is appropriate to examine together, the referring court asks, in essence, whether the third paragraph of Article 267 TFEU 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 EU law and without referring to the Court of Justice those questions concerning the interpretation of EU law.
48
According 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).
49
The 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).
50
In the present case, although the third and fourth questions concern 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.
51
In 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.
52
In those circumstances, it is necessary to reformulate the third and fourth questions referred for a preliminary ruling to the effect that, by those questions, 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.
53
It 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).
54
Therefore, 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).
55
It 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).
56
Article 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, paragraph 69 and the case-law cited).
57
It is true that, as has been pointed out in paragraph 26 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 by that provision.
58
That 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).
59
The 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).
60
It 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).
61
The 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).
62
The 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).
63
The 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).
64
Having regard to the foregoing considerations, the answer to the third and fourth questions 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 fifth question
65
By its fifth question, the referring court asks, in essence, whether a taxable person may be refunded the VAT paid, in breach of Directive 2006/112 and of the principle of fiscal neutrality, on the actual gross margin of gambling and betting which that taxable person offers.
66
In the present case, although the referring court refers, in its fifth question, to the method of calculating the refund of VAT paid in breach of EU law, it should be noted that it does not provide any explanation in that regard in its order for reference.
67
By contrast, it is apparent from that decision that, by its fifth 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 applicant in the main proceedings would have a right to a refund of the amount of VAT paid on the basis of that legislation.
68
That 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).
69
In those circumstances, and in the light of the case-law referred to in paragraphs 48 and 49 above, it is necessary to reformulate the fifth 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.
70
It 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).
71
It 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).
72
However, 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 the refund 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 adjustment in the case of incorrect rate), C‑606/22, EU:C:2024:255, paragraphs 34 and 35).
73
That 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).
74
Accordingly, 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 adjustment in the case of incorrect rate), C‑606/22, EU:C:2024:255, paragraph 28).
75
It 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 adjustment in the case of incorrect rate), C‑606/22, EU:C:2024:255, paragraph 38).
76
It follows that the answer to the fifth 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.
Costs
77
Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the referring court, the decision on costs is a matter for that court. Costs incurred in submitting observations to the Court, other than the costs of those parties, are not recoverable.
On those grounds, the Court (First Chamber) hereby rules:
1.
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 and participation in other forms of gambling offered offline and, on the other hand, participation in forms of gambling other than lotteries offered online, by excluding the latter from the value added tax exemption applicable to the former, provided that the objective differences between those 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.
2.
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.
3.
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.
