SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-28/23 
 
2  
 
Subject matter of the main proceedings 
Request for a preliminary ruling – Construction of a football stadium – Public 
works contract – Agreement to enter into a future agreement– Grant agreement – 
Classification of an agreement as a public contract – Absolute and relative 
invalidity of an agreement – Directives 2014/24/EU, 2004/18/EC and 89/665/EEC 
Subject matter and legal basis of the request 
Interpretation of EU law, Article 267 TFEU 
Questions referred for a preliminary ruling 
1 Do a grant agreement and an agreement to enter into a future sales 
agreement, concluded between a ministry (the State) and a person governed by 
private law selected outside competition procedures, constitute ‘public works 
contracts’ within the meaning of Article 1(2)(b) of Directive 2004/18 or 
Article 2(6)(c) of Directive 2014/24 where the grant agreement constitutes State 
aid approved by the European Commission for the purposes of Article 107(3)(c) 
TFEU, the grant agreement contains an obligation on the State to grant a subsidy 
as well as an obligation on the person governed by private law to construct the 
building in accordance with conditions specified by the ministry and to allow a 
sports organisation to use a part of that building, and the agreement to enter into a 
future agreement contains a unilateral option conferred on the person governed by 
private law in the form of an obligation on the State to purchase the constructed 
building, while those agreements constitute a framework of mutual obligations 
between the ministry and the person governed by private law which are linked in 
terms of time and subject matter? 
2 Does Article 1(2)(b) of Directive 2004/18 or Article 2(6)(c) of Directive 
2014/24 preclude national legislation of a Member State under which any legal act 
which by its content or purpose contravenes or circumvents the law or is contrary 
to accepted principles of morality is absolutely invalid (that is to say, from the 
outset/ex tunc) where that infringement of the law consists of a serious 
infringement of the rules on public procurement? 
3 Do Article 2d(1)(a) and Article 2d(2) of Directive 89/665 preclude national 
legislation of a Member State under which any legal act which by its content or 
purpose contravenes or circumvents the law or is contrary to accepted principles 
of morality is absolutely invalid (that is to say, from the outset/ex tunc) where that 
infringement of the law consists of a serious infringement (circumvention) of the 
rules on public procurement, as in the main proceedings?

4 Must Article 1(2)(b) of Directive 2004/18 or Article 2(6)(c) of Directive 
2014/24 be interpreted as precluding ex tunc the assumption that an agreement to 
enter into a future sales agreement, such as that at issue in the main proceedings, 
has produced legal effects? 
Provisions of European Union law [and case-law] relied on 
Directive 2004/18/EC of the European Parliament and of the Council of 31 March 
2004 on the coordination of procedures for the award of public works contracts, 
public supply contracts and public service contracts; Article 1(2)(b) 
Directive 2014/24/EU of the European Parliament and of the Council of 
26 February 2014 on public procurement and repealing Directive 2004/18/EC; 
Article 2(6)(c) and Article 18(1) 
Council Directive 89/665/EEC of 21 December 1989 on the coordination of the 
laws, regulations and administrative provisions relating to the application of 
review procedures to the award of public supply and public works contracts;

circumvents the law or is contrary to accepted principles of morality shall be 
invalid’ (absolute invalidity of a legal act) 
– Paragraph 40a: ‘If the ground for invalidity of a legal act arises from 
Paragraph 49a, [Paragraph] 140, Paragraph 145(1), Paragraph 479, 
Paragraph 589 or Paragraph 701(1), the legal act shall be deemed to be valid, 
unless the person affected by the legal act claims that it is invalid. Invalidity 
cannot be claimed by the person who caused it. The same applies if the legal 
act was not performed in the form stipulated by the parties (Paragraph 40). If a 
legal act is contrary to the generally applicable rules on prices, it shall be

Succinct presentation of the facts and procedure in the main proceedings 
1 The Government of the Slovak Republic (‘the Government’) adopted a number of 
resolutions between 2006 and 2013 with the intention of constructing a Národný 
futbalový štadión (national football stadium; ‘the stadium’) in Slovakia which 
would meet UEFA standards. The investor/contractor for the project was to be 
selected through an open procedure. 
2 On 10 July 2013, the Government adopted, without conducting any tender or 
competition procedure, Resolution No 400/2013, under which the Ministerstvo 
školstva, vedy, výskumu a športu Slovenskej republiky (Ministry of Education, 
Science, Research and Sport of the Slovak Republic; ‘the Ministry of Education’) 
was to conclude with a specific company, namely Národný futbalový štadión, a. s. 
(the legal predecessor of the applicant, NFŠ, a. s.), a memorandum which was to 
set out the conditions for the grant of a subsidy and the construction of the 
stadium. The final text of that memorandum already formed part of the 
Government Resolution in question. The memorandum o spolupráci pri realizácii 
výstavby a prevádzke športovej infraštruktúry „Národný futbalový štadión“ 
(memorandum on cooperation in constructing and operating the sports 
infrastructure ‘Národný futbalový štadión’ (national football stadium)’; ‘the 
memorandum’) was signed on 11 July 2013. 
3 On 15 August 2013, the Ministry of Education concluded with Národný futbalový 
štadión, a. s., the Zmluva o podmienkach poskytnutia dotácie na výstavbu 
Národného futbalového štadióna (Agreement on the conditions for granting a 
subsidy for the construction of a national football stadium). Pursuant to that 
agreement, Call for Applications for the grant of subsidies in the field of sport 
No 2013-11- ‘Národný futbalový štadión’ (‘the call for applications’) was 
published within 60 days of the agreement’s entry into force, that is to say, on 
20 September 2013. Under the call for applications, the only person stated as 
eligible to submit an application was Národný futbalový štadión, a. s.. 
NFŠ

4 On 21 November 2013, the Ministry of Education concluded with Národný 
futbalový štadión, a. s., on the basis of the call for applications, the Zmluva o 
poskytnutí dotácie zo štátneho rozpočtu (Agreement on the grant of a subsidy 
from the State budget). The subsidy was granted without making a selection from 
a wider range of interested parties (outside competition procedures), since, in 
accordance with the wording of the call for applications, the only eligible person 
was Národný futbalový štadión, a. s., as set out in Government Resolution 
No 400/2013. 
5 The Ministry of Education undertook to grant a subsidy in the amount of 
EUR 27 200 000 for the stadium construction project. 
6 Národný futbalový štadión, a. s., undertook to co-finance the stadium in an 
amount corresponding to at least 60% of the expenditure incurred in its 
construction. 
7 On 10 May 2016, the Ministry of Education, acting on behalf of the Slovak 
Republic, as the future purchaser, concluded with NFŠ, a. s., as the future seller, 
Zmluva o budúcej (kúpnej) zmluve č. 0385/2016 (Agreement to enter into a future 
(sales) agreement No 0385/2016) [(‘the agreement to enter into a future 
agreement’)], which set out the conditions for the conclusion of the promised sales 
agreement for the stadium on the basis of the call to NFŠ, a. s., whereby the risks 
attached to owning and operating the stadium would be transferred to the Slovak 
Republic upon sale. [The agreement to enter into a future agreement] included 
annexes containing detailed specifications of the technical and material 
parameters of the constructed building, namely the stadium. The characteristics of 
the building were thus determined by the Slovak Republic, as represented by the 
Ministry of Education. 
8 On the same date, namely 10 May 2016, the Ministry of Education concluded 
with the applicant Annex No. 1 to the grant agreement, which excluded the 
possibility of free use of certain areas of the stadium by the Slovenský futbalový 
zväz (Slovak Football Association, Slovakia). 
9 For [the agreement to enter into a future agreement] to produce legal effects, three 
conditions had to be satisfied, namely (1) the publication of the agreement in the 
State Central Register of Contracts, (2) the issuing by the European Commission 
of a decision assessing the transactions provided for in [the agreement to enter 
into a future agreement] and the grant agreement from the perspective of the 
permissibility of State aid, and (3) the adoption of a position by the Úrad pre 
verejné obstarávanie Slovenskej republiky (Office for Public Procurement of the 
Slovak Republic, Slovakia) [(‘the Office’)], as the national public procurement 
supervisory authority, on the compatibility of the transactions provided for in [the 
agreement to enter into a future agreement] with the rules on public procurement. 
10 By Decision SA.46530 of 24 May 2017, the European Commission declared the 
State aid in the form of the above subsidy and sales option compatible with the 
SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-28/23 
 
6  
internal market for the purposes of Article 107(3)(c) TFEU, which meant that the 
second of the abovementioned conditions for [the agreement to enter into a future 
agreement] to produce legal effects was satisfied. 
11 With regard to the third of the abovementioned conditions for [the agreement to 
enter into a future agreement] to produce legal effects, [the Office] did not, despite 
a request by the Ministry of Education, adopt a binding position; nor did it carry 
out any checks in relation to the transaction provided for in [the agreement to 
enter into a future agreement]. It therefore did not approve the transaction 
provided for in that agreement. The Chair of [the Office] merely sent a non-
binding response in the form of a letter dated 8 July 2016. 
12 The following legal disputes are currently underway: (1) the Ministry of 
Education and the Slovak Republic are suing NFŠ, a. s., for repayment of the 
entire amount of the subsidy in the amount of EUR 27 200 000, plus interest and 
costs, on the ground that the grant agreement is absolutely invalid in that it is 
incompatible with the law, (2) NFŠ, a. s., is suing the Ministry of Education and 
the Slovak Republic to determine the content of the unenforceable provision of 
[the agreement to enter into a future agreement] which lays down the procedure 
for calculating the sales price of the stadium, (3) NFŠ, a. s., is suing the Slovak 
Republic and the Ministry of Education for payment of a contractual penalty in 
the amount of EUR 48 000 000 for failure to conclude the promised sales 
agreement for the stadium under the terms of [the agreement to enter into a future 
agreement], and (4) NFŠ, a. s., is suing the Slovak Republic and the Ministry of 
Education for damages in the amount of EUR 47 349 262.73 in connection with 
the stadium project, plus interest and costs. 
The essential arguments of the parties in the main proceedings 
13 The applicant claims that without State support in the form of a subsidy and sales 
option, construction of the stadium would have been unfeasible for a private 
investor (the applicant). State support for that project consisted of two 
instruments, namely (i) the subsidy provided for in the grant agreement and (ii) 
the option provided for in [the agreement to enter into a future agreement]. In the 
view of the applicant, the [Agreement on the conditions for granting a subsidy for 
the construction of a national football stadium] and the memorandum jointly 
created a legal framework which was intended to guarantee that, if the applicant 
were successful in the call for applications for the grant of a subsidy for the 
construction of a stadium, it would be assured of State support. 
14 The applicant further claims that that no obligation to construct the stadium and 
subsequently sell it to the Ministry of Education arises from [the agreement to 
enter into a future agreement]. In the view of the applicant, that agreement does 
not meet the definition of a public contract, since, according to the case-law of the 
Court of Justice, in order for an agreement to be regarded as a public contract, 
there must be an obligation to perform certain works, the performance of which is 
NFŠ 
 
7 
judicially enforceable. However, [the agreement to enter into a future agreement] 
contains no such obligation. The applicant disputes the assertion that [the 
agreement to enter into a future agreement] is for consideration, arguing that that 
agreement merely concerns an option granted to the applicant and not an 
obligation on its part to implement the agreement. 
15 The Ministry of Education contends that the rules on public procurement were 
infringed in the construction of the stadium. It expresses the view that the 
Agreement on the grant of a subsidy from the State budget was concluded in 
breach of the law, since the subsidy was granted and the agreement was concluded 
on the basis of a call [for applications] which did not provide a competition 
between the persons applying for funds. Thus, in the view of the Ministry of 
Education, the grant agreement is invalid within the meaning of Paragraph 39 of 
the Civil Code (absolute invalidity). 
16 The Ministry of Education further argues that the failure to apply public 
procurement procedures and the essentially direct award of the contract to NFŠ, a. 
s., infringed not only public procurement legislation, but also other legislation of 
the Slovak Republic which provided for the application of a competition or 
established an obligation to manage public funds sparingly and effectively. 
17 The Ministry of Education considers that the Agreement on the grant of a subsidy 
from the State budget and [the agreement to enter into a future agreement] 
constitute a set of mutual rights and obligations of the Ministry of Education and 
NFŠ, a. s., which are linked in terms of time and subject matter, by which there 
has been an intentional circumvention of Zákon č. 25/2006 Z. z. o verejnom 
obstarávaní a o zmene a doplnení niektorých zákonov (Law No 25/2006 [of 
14 December 2005] on public procurement and amending and supplementing 
certain laws), as subsequently amended, or Zákon č. 343/2015 Z. z. o verejnom 
obstarávaní [a o zmene a doplnení niektorých zákonov] (Law No 343/2015 [of 
18 November 2015] on public procurement [and amending and supplementing 
certain laws]), and is therefore absolutely invalid from the outset as it is contrary 
to or circumvents the law on public procurement. 
18 The Ministry of Education is of the view that the selection of the contractor or 
investor should have taken place through a transparent competition and preference 
should not have been given to a particular person governed by private law. 
19 The Ministry of Education contends that the grant agreement laid down the 
conditions which the stadium had to satisfy (it had to be a Category 4 Stadium 
within the meaning of UEFA’s regulations [and] meet certain requirements 
regarding capacity, equipment, dimensions, technical parameters, training of 
sports representatives, and so on). The Ministry of Education was a member of the 
committee managing and monitoring the construction of the stadium, which gave 
it an opportunity to comment on the progress of the construction and use thereof, 
as well as on other issues concerning construction, financing, and the analyses and 
opinions of external advisors. The tasks and control of the monitoring committee 
SUMMARY OF THE REQUEST FOR A PRELIMINARY RULING – CASE C-28/23 
 
8  
were also laid down directly in [the agreement to enter into a future agreement] 
(point 4.1.1 of that agreement). 
20 Furthermore, the Ministry of Education considers that point 2.2 of [the agreement 
to enter into a future agreement] expressly provides for a pecuniary consideration 
by calculating the sales price (also stating the upper limit thereof). The agreement 
itself therefore sets out the procedure for determining the price at which the State 
is to buy the stadium under the promised sales agreement. The entire transaction 
provided for in [the agreement to enter into a future agreement] can therefore be 
actually valued in monetary terms and it is completely irrelevant whether the final 
sum is entered into the promised sales agreement, since it is already absolutely 
clear from [the agreement to enter into a future agreement] that there is a 
transaction for consideration between the parties thereto. Acceptance of the 
concept of ‘consideration/not for consideration’ put forward by NFŠ, a. s., would 
make it possible in practice, by this deliberate and unlawful method, to transform 
any agreement for consideration into an agreement not for consideration, and this 
would be done by transforming an agreement for consideration into a commitment 
to a future agreement, with the right of a ‘unilateral option’ to conclude an 
agreement for consideration being granted to only one of the contracting parties 
(the tenderer). 
Succinct presentation of the reasoning in the request for a preliminary ruling 
21 It is necessary to clarify whether (i) an agreement on the grant of a subsidy for the 
construction of a building which, in addition to commercial purposes, will also 
serve publicly to promote sport and (ii) an agreement to enter into a future 
agreement, concluded between the Ministry of Education (the State) and a person 
governed by private law selected outside competitive procedures, constitute 
‘public works contracts’ within the meaning of Article 1(2)(b) of Directive 
2004/18 or Article 2(6)(c) of Directive 2014/24 where: 
– the grant agreement constitutes State aid approved by the European 
Commission for the purposes of Article 107(3)(c) TFEU, 
– the grant agreement contains an obligation on the State to grant a 
subsidy as well as an obligation on the person governed by private law 
to construct the building in accordance with conditions specified by the 
Ministry of Education and to allow a sports organisation to use a part 
of that building, and 
– the agreement to enter into a future agreement contains a unilateral 
option conferred on the person governed by private law in the form of 
an obligation on the State to purchase the constructed building, 
NFŠ 
 
9 
– while those agreements constitute a framework of mutual obligations 
between the Ministry of Education and the person governed by private 
law which are linked in terms of time and subject matter. 
22 The parties to the main proceedings argue that it is not settled in the relevant 
academic legal writings and case-law whether an infringement of the law on 
public procurement gives rise to absolute invalidity of an agreement (invalidity 
from the outset – ex tunc) or whether it involves relative invalidity of that 
agreement (ex nunc). 
23 In this regard, the applicant points, in its application for determination of the 
content of [the agreement to enter into a future agreement] in so far as it fixes the 
sales price, to the fact that ‘neither in the relevant academic legal writings nor in 
the case-law has it been fully settled whether an infringement of the law on public 
procurement gives rise to absolute or relative invalidity of an agreement’. In this 
context, the applicant argues that the invalidity of a legal act (agreement) cannot 
be claimed by the person who caused that invalidity (Paragraph 40a of the Civil 
Code). 
24 The Ministry of Education is seeking a declaration of absolute invalidity of the 
legal act (agreement), since the contested set of agreements leads to a blatant 
circumvention of the rules on public procurement laid down in the law on public 
procurement and in EU law. 
25 Case-law at the national level on this issue is not uniform. The applicant refers to 
judgments of the Krajský súd v Bratislave (Regional Court, Bratislava, Slovakia) 
which has applied the concept of relative invalidity of an agreement in relation to 
an infringement of the rules on public procurement. The Ministry of Education, on 
the other hand, refers to a decision of the Ústavný súd (Constitutional Court of the 
Slovak Republic, Slovakia), which links an infringement of the rules on public 
procurement to absolute invalidity ex tunc, and a decision of the Krajský súd v 
Bratislave (Regional Court, Bratislava), in which that court held that the award of 
a contract which should have been awarded in accordance with the procedure laid 
down by [public procurement] law, but was not so awarded, also renders such an 
agreement absolutely invalid. 
26 In the light of the foregoing, it is necessary to determine whether Article 2d(1)(d) 
and Article 2d(2) of Directive 89/665 preclude national legislation of a Member 
State under which any legal act which by its content or purpose contravenes or 
circumvents the law or is contrary to accepted principles of morality is absolutely 
invalid (that is to say, from the outset/ex tunc) where that infringement of the law 
consists of a serious infringement (circumvention) of the rules on public 
procurement.
