“5(1) States, regional and local government authorities and other bodies governed by public law shall not be considered taxable persons in respect of the activities or transactions in which they engage as public authorities, even where they collect dues, fees, contributions or payments in connection with these activities or transactions. (2) However, when they engage in such activities or transactions, they shall be considered taxable persons in respect of these activities or transactions where treatment as non-taxable persons would lead to significant distortions of competition. (3) In any case, these bodies shall be considered taxable persons in relation to the activities listed in Annex D, provided they are not carried out on such a small scale as to be negligible.”
“… the significant distortions of competition, to which the treatment as non-taxable persons of bodies governed by public law acting as public authorities would lead, must be evaluated by reference to the activity in question, as such, without such evaluation relating to any local market in particular.”
“… principally activities engaged in by bodies governed by public law acting as public authorities, which, while fully economic in nature, are closely linked to the exercise of rights and powers of public authority. In those circumstances, the fact that such bodies are not subject to VAT on those activities does not potentially have an anticompetitive effect, inasmuch as they are generally engaged in exclusively, or almost exclusively, by the public sector.”
“37. It is precisely to those activities that the second subparagraph of Article 4(5) of the Sixth Directive applies, in providing that bodies governed by public law, even when they act as public authorities, are to be considered taxable persons where their treatment as non-taxable persons would lead to significant distortions of competition. 38. The second and the third subparagraphs of Article 4(5) of the Sixth Directive are, consequently, closely linked since they pursue the same objective, namely the treatment of bodies governed by public law as taxable persons, even when they are acting as public authorities. Those subparagraphs are thus subject to the same logic, by which the Community legislature intended to limit the scope of the treatment of bodies governed by public law as non-taxable persons, so that the general rule stated in Articles 2(1) and 4(1) and (2) of that directive, under which any activity of an economic nature is, in principle, to be subject to VAT, is observed. 39. Consequently, the second and third subparagraphs of Article 4(5) of the Sixth Directive are to be interpreted as a whole. 40. It follows that the treatment of bodies governed by public law as taxable persons, either on the basis of the second subparagraph of Article 4(5) of the Sixth Directive, or on that of the third subparagraph of that provision, results from the carrying-on, as such, of a given activity, irrespective of whether or not those bodies face competition at the level of the local market on which they engage in that activity.’”
“60. It is important to record, as is clear from paragraph 30 of the present judgment, that the treatment of bodies governed by public law as non-taxable persons under the first subparagraph of Article 4(5) of the Sixth Directive constitutes a derogation from the general rule that any activity of an economic nature be subjected to VAT, and that this provision must, therefore, be interpreted strictly. But the second subparagraph of Article 4(5) restores that general rule in order to avoid such treatment of those bodies leading to significant distortions of competition. The latter provision cannot therefore be construed narrowly. 61. The scope of the first subparagraph of Article 4(5) of the Sixth Directive would be enlarged unduly if the treatment, under the second subparagraph of Article 4(5), of those bodies as taxable persons had to be confined to cases of distortion of actual competition, which would, were they confronted only with potential competition, permit their treatment as non-taxable persons. 62. In addition, the treatment of those same bodies as non-taxable persons is liable, by itself, to discourage potential competitors from entering the market for the provision of off-street car-parking facilities. 63. It follows that the expression ‘would lead to’, for the purposes of the second subparagraph of Article 4(5) of the Sixth Directive, encompasses not only actual competition, but also potential competition. 64. However, the purely theoretical possibility of a private operator entering the relevant market, which is not borne out by any matter of fact, or by any objective evidence or by any analysis of the market, cannot be assimilated to the existence of potential competition. To make such an assimilation, that possibility must be real, and not purely hypothetical. 65. Consequently, the reply to the second question must be that the expression ‘would lead to’ is, for the purposes of the second subparagraph of Article 4(5) of the Sixth Directive, to be interpreted as encompassing not only actual competition, but also potential competition, provided that the possibility of a private operator entering the relevant market is real, and not purely hypothetical.”
“75. … under the third subparagraph of Article 4(5) of the Sixth Directive, bodies governed by public law are taxable persons for the activities listed in Annex D thereto, provided they are not carried out on such a small scale as to be ‘negligible’. In other words, the treatment of those bodies as non-taxable persons is permitted provided that those activities are negligible, assuming thus that the distortions of competition which would result would also be negligible. 76. Since, as is clear from paragraph 38 of the present judgment, the second and third subparagraphs of Article 4(5) of the Sixth Directive are closely linked since they pursue the same objective and since they are subject to the same logic, the word ‘significant’ is to be interpreted as meaning that the treatment of public bodies as non-taxable persons can be permitted only in cases where it would lead only to negligible distortions of competition. … 79. Therefore the reply to the third question must be that the word ‘significant’ is, for the purposes of the second subparagraph of Article 4(5) of the Sixth Directive, to be understood as meaning that the actual or potential distortions of competition must be more than negligible.”
