Preliminary observations
30
The European Commission submits that, despite the referring tribunal’s findings in that respect, it is far from clear whether, in operating the two toll roads at issue in the main proceedings and collecting tolls, the NRA is to be regarded as acting as a public authority.
31
It must be recalled, first, that it is the responsibility of the national court to define the legislative and factual context of the dispute before it (see, to that effect, judgment of
21 September 2016,
Radgen
, C‑478/15, EU:C:2016:705, paragraphs 27 and 32
and the case-law cited).
32
Secondly, in the context of the cooperation between the Court and the national courts provided for in Article 267 TFEU, it is solely for the national court before which a dispute has been brought, and which must assume responsibility for the subsequent judicial decision, to determine in the light of the particular circumstances of the case 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. The right to determine the questions to be put to the Court thus devolves on the national court alone and the parties to the main proceedings may not change their tenor (judgment of
16 October 2014,
Welmory
, C‑605/12, EU:C:2014:2298, paragraph 33
and the case-law cited).
33
In the present case, it is apparent from the order for reference that the referring tribunal considers unequivocally that, in the dispute in the main proceedings, the NRA is acting as a public authority when it engages in the activity of making road infrastructure available on payment of a toll.
34
In those circumstances, the Court must proceed on the basis that the NRA, a body governed by public law, acts as a public authority in its activity of making the road infrastructure concerned available on payment of a toll, and therefore that that activity must be regarded as falling within the scope of Article 13(1) of the VAT Directive.
The questions referred
35
By its two questions, which should be considered together, the referring tribunal seeks essentially to know whether the second subparagraph of Article 13(1) of the VAT Directive must be interpreted as meaning that, in a situation such as that in the main proceedings, a body governed by public law which carries on an activity consisting in providing access to a road on payment of a toll must be regarded as competing with private operators who collect tolls on other toll roads pursuant to an agreement with the public law body concerned under national statutory provisions.
36
It should be recalled that the second subparagraph of Article 13(1) of the VAT Directive provides for a limitation of the rule stated in the first subparagraph of that provision that bodies governed by public law are to be treated as non-taxable persons for VAT purposes in respect of the activities or transactions in which they engage as public authorities. That second subparagraph thus aims to restore the general rule set out in Article 2(1) and Article 9 of the VAT Directive, according to which any activity of an economic nature is in principle to be subject to VAT, and cannot therefore be construed narrowly (see, by analogy, judgment of
4 June 2009,
SALIX Grundstücks-Vermietungsgesellschaft
, C‑102/08, EU:C:2009:345, paragraphs 67 and 68
).
37
However, that cannot mean that the second subparagraph of Article 13(1) of the VAT Directive should be interpreted in such a way that the derogation from treatment as a taxable person for VAT laid down in the first subparagraph of Article 13(1) of the directive for bodies governed by public law acting as public authorities is deprived of effectiveness (see, to that effect, judgment of
20 November 2003,
Taksatorringen
, C‑8/01, EU:C:2003:621, paragraphs 61 and 62
, and of
25 March 2010,
Commission v Netherlands
, C‑79/09, not published, EU:C:2010:171, paragraph 49
).
38
Under the second subparagraph of Article 13(1) of the VAT Directive, those bodies are to be regarded as taxable persons in respect of the activities or operations in which they engage as public authorities, where their treatment as non-taxable persons would lead to significant distortions of competition.
39
According to the Court’s case-law on that provision, first, what is envisaged here is the situation in which bodies governed by public law engage in activities which may also be engaged in, in competition with them, by private economic operators. The aim is to ensure that those private operators are not placed at a disadvantage because they are taxed while those bodies are not (see, to that effect, judgment of
25 March 2010,
Commission v Netherlands
, C‑79/09, not published, EU:C:2010:171, paragraph 90
and the case-law cited).
40
Secondly, that limitation of the rule that bodies governed by public law acting as public authorities are treated as non-taxable persons for VAT purposes is only a conditional limitation. Its application involves an assessment of economic circumstances (see, to that effect, judgment of
17 October 1989,
Comune di Carpaneto Piacentino and Others
, 231/87 and 129/88, EU:C:1989:381, paragraph 32
).
41
Thirdly, the significant distortions of competition which treatment as non-taxable persons of bodies governed by public law acting as public authorities would lead to must be evaluated by reference to the activity in question, as such, without that evaluation relating to any particular market, and by reference not only to actual competition, but also to potential competition, provided that the possibility of a private operator entering the relevant market is real and not purely hypothetical (judgments of
25 March 2010,
Commission v Netherlands
, C‑79/09, not published, EU:C:2010:171, paragraph 91
and the case-law cited, and of
29 October 2015,
Saudaçor
, C‑174/14, EU:C:2015:733, paragraph 74
).
42
The purely theoretical possibility of a private operator entering the relevant market, which is not borne out by any matter of fact, any objective evidence or any analysis of the market, cannot be assimilated to the existence of potential competition (judgment of
16 September 2008,
Isle of Wight Council and Others
, C‑288/07, EU:C:2008:505, paragraph 64
).
43
As follows from the wording of the second subparagraph of Article 13(1) of the VAT Directive and from the case-law on that provision, its application presupposes, first, that the activity in question is carried on in competition, actual or potential, with that carried on by private operators and, secondly, that the different treatment of those activities for VAT purposes leads to significant distortions of competition, which must be assessed having regard to economic circumstances.
44
It follows that the mere presence of private operators on a market, without account being taken of matters of fact, objective evidence or an analysis of the market, cannot demonstrate the existence either of actual or potential competition or of a significant distortion of competition.
45
In the present case, according to the documents submitted to the Court, the primary function of the NRA is to ensure the availability of a safe and efficient network of national roads. For that purpose, it has overall responsibility for the planning and construction of all national roads and for the supervision of works for the construction and maintenance of those roads. On that basis, only it can prepare a plan for establishing a toll scheme for access to those roads and make the bye-laws it considers necessary for their operation and management, those bye-laws setting the maximum amount of the tolls which may be levied for access to a toll road, whether it is operated by the NRA or a private operator.
46
It also appears from those documents that private operators can enter the market of making road infrastructure available on payment of a toll only if the NRA authorises them to do so. Furthermore, the fact that the management of a national road has been entrusted to a private operator does not in any way alter the fact that the NRA always retains ultimate responsibility for national roads, so that, if the private operator is no longer willing or no longer able to fulfil his commitments, the NRA is required to ensure the proper functioning of those roads.
47
It appears in this respect that, for the Westlink motorway, the agreement between the NRA and the private operator provided for the operator to collect the tolls by means of a conventional toll barrier system. However, moving from toll booths with barriers to an electronic barrier-free toll system, which was necessary to ensure a better traffic flow on that motorway, required substantial investment and involved assuming the risk inherent in operating a barrier-free toll system. As the private operator was unwilling to make that investment without additional commitments on the part of the NRA, the NRA negotiated the termination of the agreement, took over operation of the Westlink motorway in August 2008, and installed an electronic toll system in the public interest of ensuring the flow of traffic.
48
It is clear that in such circumstances the activity of making road infrastructure available on payment of a toll, which is thus not limited to the collection of tolls, is carried out exclusively by the NRA under conditions that are such as to ensure in all circumstances that a safe and efficient network of national roads is available. In doing so, the NRA assumes, on its own account or where a private operator withdraws, in compliance with specific statutory obligations that apply only to it, the function of operating and maintaining that network.
49
It is, moreover, common ground that there is no real possibility of a private operator entering the market in question by constructing a road that could compete with already existing national roads.
50
In those circumstances, it is apparent that the NRA engages in its activity of making road infrastructure available on payment of a toll within the legal scheme peculiar to it. Consequently, as the referring tribunal also found, that activity cannot be regarded as being carried on in competition with that, carried on by private operators, consisting in collecting tolls on other toll roads pursuant to an agreement with the NRA in accordance with national legislative provisions. Furthermore, in line with the case-law referred to in paragraph 42 above, there is no potential competition either, in so far as the possibility of private operators carrying on the activity in question on the same conditions as the NRA is purely theoretical. Accordingly, the second subparagraph of Article 13(1) of the VAT Directive is not applicable to a situation in which, as in the dispute in the main proceedings, there is no real competition, actual or potential, between the public law body in question and private operators.
51
In the light of all the foregoing, the answer to the questions referred is that the second subparagraph of Article 13(1) of the VAT Directive must be interpreted as meaning that, in a situation such that in the main proceedings, a body governed by public law which carries on an activity consisting in providing access to a road on payment of a toll may not be regarded as competing with private operators who collect tolls on other toll roads pursuant to an agreement with the public law body concerned under national statutory provisions.
