To determine whether a measure is selective it is necessary to compare the beneficiary companies to other companies which are in a similar situation and determine whether the latter receive the same advantage.
At the outset, the Court of Justice reiterated that “(58) the assessment of [selectivity] requires it to be determined whether, under a particular legal regime, 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”.
“(59) As regards the examination of the condition relating to the selectivity of an aid measure, the Court has held that that examination must be supported by sufficient reasons to allow full judicial review, in particular of the question whether the situation of operators benefiting from the measure is comparable with that of operators excluded from it”.
“(60) In this case, in paragraph 86 of the judgment under appeal, the General Court […] [found that] the measure at issue benefited only the broadcasting sector and that, within that sector, the measure at issue concerned only the undertakings active on the terrestrial platform market.”
“(61) That reasoning is vitiated by an error of law. The statement of reasons in the decision at issue — like, moreover, the statement of reasons in the judgment under appeal — contains no indication of the reasons why undertakings active in the broadcasting sector should be regarded as being in a factual and legal situation comparable to that of undertakings active in other sectors or why undertakings using terrestrial technology should be regarded as being in a factual and legal situation comparable to that of undertakings using other technologies. The Commission’s argument that no reasoning was necessary in that respect, since the selectivity condition is automatically satisfied if a measure applies exclusively to a specific economic sector or to undertakings in a particular geographic area, cannot be accepted. The Court has held that a measure which benefits only one economic sector or some of the undertakings in that sector is not necessarily selective. It is selective only if, within the context of a particular legal regime, it has the effect of conferring an advantage on certain undertakings over others, in a different sector or the same sector, which are, in the light of the objective pursued by that regime, in a comparable factual and legal situation (judgment of 21 December 2016, Commission v Hansestadt Lübeck, C‑524/14 P, EU:C:2016:971, paragraph 58).” For this reason, the Court of Justice upheld the plea.
It is worth recalling that the judgment in the Lübeck case concerned the charging of landing fees which were lower than those at other airports. The lower landing fees charged by Lübeck were found not to be selective because they applied to all airlines that used that airport and because they were decided autonomously by Lübeck airport. In other words, they applied uniformly to all airlines to which they could possibly apply. This was the case of a measure adopted by a sub-national authority and which had a narrow sectoral scope [applied only to one sector] and limited geographic application [the area of Lübeck]. Hence the case of Lübeck is not really comparable to measures adopted by central governments.
It is also worth citing the relevant text of the judgment of the General Court [here is a rough, non-official translation]:
(84) It should be noted that the criterion of selectivity within the meaning of Article 107 (1) TFEU requires that the measure in question favours certain undertakings or certain products. [.].. It must be held that [the measure in question] does not apply without distinction to all economic operators. It cannot therefore be regarded as a general measure of fiscal or economic policy which does not constitute State aid within the meaning of Article 107 TFEU. (85) As the applicants claim that the criterion of selectivity is not fulfilled because of the lack of comparability between land platform operators and that of other operators, it is sufficient to point out that, […], the notion of State aid does not refer to State measures introducing a differentiation between undertakings and, therefore, a priori selective, where that differentiation results from the nature or the economy of the system in which they fall […]. In the present case, the measure in question differentiated in that it subsidised the broadcasting sector in order to deploy digital television […]. (86) Regarding the argument that the statement of reasons for the selective nature of the measure in question is insufficient, it must be held that it appears from recital 113 of the contested decision that, according to the Commission, the advantage was selective, since the measure only benefited the broadcasting sector and, in this sector, this measure only concerned companies operating in the terrestrial platform market. Such a statement of reasons is sufficient in the present case in view of the precision of that criterion in the case-law (see paragraphs 84 and 85 above).
It is obvious that the General Court considered sufficient that a sectoral measure is prima facie selective. But this was not enough for the Court of Justice. The problem is that the Court of Justice does not indicate what is the required standard of comparability or, on the other hand, difference.
At any rate, when an appeal is well founded and the decision of the General Court is set aside, the Court of Justice may itself give final judgment in the matter. For this reason it proceeded to annul Commission decision 2014/489. This means that the Commission will have to re-open the case and correct the defective part of its decision. That is, the Commission will have to explain why the beneficiary broadcasters were in the same situation as other broadcasters or other companies in other sectors.
How will the Commission repair its own assessment of selectivity?
At first glance, this appears to be an impossible task. By definition a measure that supports digital terrestrial broadcasting cannot apply to non-terrestrial broadcasting or to other sectors. Moreover, no two companies are identical. How then can different companies be found to be “comparable”? Hence, one may conclude that, “in the light of the objective pursued by that regime” [i.e. the measure in question], no other company is in the same situation as terrestrial digital broadcasters. This, however, would be the wrong conclusion.
The measure was certainly selective, not just because it favoured a particular technology but primarily because it relieved from investment costs only certain broadcasters while it did not provide the same relief to companies investing in other technologies or sectors. But how can this be inferred, one may ask, since the measure in question did not refer to investment in other technologies or sectors?
According to the Court of Justice in case C-270/15 P, Belgium v Commission, a Belgian measure that paid for the cost of tests for BSE was selective because Belgium did not pay for the cost of tests for other diseases or for the cost of other obligatory tests in other sectors. In other words, the selectivity of a measure can be inferred by its own narrow scope of application. The Belgian measure provided relief only for BSE tests although similar tests were carried out in other sectors.
A similar reasoning was developed by the Court of Justice in case C-106/09 P, Commission v Gibraltar. A new tax regime in Gibraltar was designed in such a way as not to apply to offshore companies. But the Court of Justice inferred that it was selective by the fact that there was a mismatch between the aim of the tax [which was to tax profits] and the method by which the tax was levied. The method was too narrow as the tax was levied on the number of staff and size of office space.
The following example can illustrate how the aim or scope of application of an aid measure determines which companies are in a comparable situation. Assume that, following an urban health study, a public authority grants aid to owners of pubs and cafes to install air filtering equipment for the purpose of improving the quality of the air during winter months when doors and windows are closed. The measure refers only to pubs and cafes where there is a high density of persons per square meter. However, given the purpose of the measure, in a comparable situation this can also be the case in clubs, restaurants and even open-plan offices.
The answer, then, to the question posed at the beginning of this section is that it is not necessary to prove that companies are identical. In fact it does not matter that they are all very different. The only thing that matters is the scope of the objective of the measure in question. That is the determinant of whether different and distinct companies are in a comparable situation.
By applying the same logic as in the Belgian and Gibraltar cases, the Commission should conclude that the Spanish measure was selective because it offered investment aid only to one sub-sector whereas investment was carried out by companies in other sectors too.
