(Request for a preliminary ruling from the Najvyšší súd Slovenskej republiky (Supreme Court of the Slovak Republic)

‛Public procurement — Qualitative selection criteria — Proof of an economic operator’s economic and financial standing — Judicial review of a decision to exclude an economic operator from a tendering procedure)’

1. In its reference to the Court of Justice for a preliminary ruling, the Najvyšší súd Slovenskej republiky (Supreme Court of the Slovak Republic) has referred three questions on the interpretation of the European Union provisions relating to the criteria for the award of public contracts and the procedures for review of decisions of contracting authorities.

2. The first two questions concern proof of the economic and financial standing of tenderers, within the meaning of Directive 2004/18/EC. ( *2 ) The referring court’s uncertainties concern proof of economic and financial standing and the time to which that proof has to relate. The third question concerns the review mechanisms provided for in Directive 89/665/EEC, ( *3 ) in relation to which the Najvyšší súd (Supreme Court) asks, in short, whether these remain effective where performance of the contract is almost complete by the time a ruling has to be given on the challenge.

I – Legal framework

A – EU law

1. The Charter of Fundamental Rights of the European Union

3. The first and second paragraphs of Article 47 provide: ‘Everyone whose rights and freedoms guaranteed by the law of the Union are violated has the right to an effective remedy before a tribunal in compliance with the conditions laid down in this Article. Everyone is entitled to a fair and public hearing within a reasonable time by an independent and impartial tribunal previously established by law. Everyone shall have the possibility of being advised, defended and represented.’

2. Directive 2004/18

4. In accordance with recital 33 in the preamble: ‘Contract performance conditions are compatible with this Directive provided that they are not directly or indirectly discriminatory and are indicated in the contract notice or the contract documents. They may, in particular, be intended to favour on-site vocational training, the employment of people experiencing particular difficulty in achieving integration, the fight against unemployment or the protection of the environment. For instance, mention may be made, amongst other things, of the requirements — applicable during performance of the contract — to recruit long-term job-seekers or to implement training measures for the unemployed or young persons, to comply in substance with the provisions of the basic International Labour Organisation (ILO) Conventions, assuming that such provisions have not been implemented in national law, and to recruit more handicapped persons than are required under national legislation.’

5. Recital 39 in the preamble states: ‘Verification of the suitability of tenderers, in open procedures, and of candidates, in restricted and negotiated procedures with publication of a contract notice and in the competitive dialogue, and the selection thereof, should be carried out in transparent conditions. For this purpose, non-discriminatory criteria should be indicated which the contracting authorities may use when selecting competitors and the means which economic operators may use to prove they have satisfied those criteria. In the same spirit of transparency, the contracting authority should be required, as soon as a contract is put out to competition, to indicate the selection criteria it will use and the level of specific competence it may or may not demand of the economic operators before admitting them to the procurement procedure.’

6. Article 26 (‘Conditions for performance of contracts’) provides: ‘Contracting authorities may lay down special conditions relating to the performance of a contract, provided that these are compatible with Community law and are indicated in the contract notice or in the specifications. The conditions governing the performance of a contract may, in particular, concern social and environmental considerations.’

7. Article 44, headed ‘Verification of the suitability and choice of participants and award of contracts’, provides in paragraph (2): ‘The contracting authorities may require candidates and tenderers to meet minimum capacity levels in accordance with Articles 47 and 48. The extent of the information referred to in Articles 47 and 48 and the minimum levels of ability required for a specific contract must be related and proportionate to the subject-matter of the contract. These minimum levels shall be indicated in the contract notice.’

8. Article 47 (‘Economic and financial standing’) stipulates: ‘1. Proof of an economic operator’s economic and financial standing may, as a general rule, be furnished by one or more of the following references: a) appropriate statements from a bank or, where appropriate, evidence of professional risk indemnity insurance; … 4. Contracting authorities shall specify, in the contract notice or in the invitation to tender, which reference or references mentioned in paragraph 1 they have chosen and which other references must be provided. 5. If, for any valid reason, the economic operator is unable to provide the references requested by the contracting authority, he may prove his economic and financial standing by any other document which the contracting authority considers appropriate.’

3. Directive 89/665 ( *4 )

9. Article 1 (‘Scope and availability of review procedures’) provides in paragraph (1): ‘… Member States shall take the measures necessary to ensure that, as regards contracts falling within the scope of Directive 2004/18/EC, decisions taken by the contracting authorities may be reviewed effectively and, in particular, as rapidly as possible in accordance with the conditions set out in Articles 2 to 2f of this Directive, on the grounds that such decisions have infringed Community law in the field of public procurement or national rules transposing that law.’

10. Article 2 (‘Requirements for review procedures’) states: ‘1. Member States shall ensure that the measures taken concerning the review procedures specified in Article 1 include provision for powers to: a) take, at the earliest opportunity and by way of interlocutory procedures, interim measures with the aim of correcting the alleged infringement or preventing further damage to the interests concerned, including measures to suspend or to ensure the suspension of the procedure for the award of a public contract or the implementation of any decision taken by the contracting authority; b) either set aside or ensure the setting aside of decisions taken unlawfully, including the removal of discriminatory technical, economic or financial specifications in the invitation to tender, the contract documents or in any other document relating to the contract award procedure; c) award damages to persons harmed by an infringement. … 4. Except where provided for in paragraph 3 and Article 1(5), review procedures need not necessarily have an automatic suspensive effect on the contract award procedures to which they relate. … 6. Member States may provide that where damages are claimed on the grounds that a decision was taken unlawfully, the contested decision must first be set aside by a body having the necessary powers. 7. Except where provided for in Articles 2d to 2f, the effects of the exercise of the powers referred to in paragraph 1 of this Article on a contract concluded subsequent to its award shall be determined by national law. Furthermore, except where a decision must be set aside prior to the award of damages, a Member State may provide that, after the conclusion of a contract in accordance with Article 1(5), paragraph 3 of this Article or Articles 2a to 2f, the powers of the body responsible for review procedures shall be limited to awarding damages to any person harmed by an infringement. 8. Member States shall ensure that decisions taken by bodies responsible for review procedures can be effectively enforced. …’

11. Article 2d (‘Ineffectiveness’) reads: ‘1. Member States shall ensure that a contract is considered ineffective by a review body independent of the contracting authority or that its ineffectiveness is the result of a decision of such a review body in any of the following cases: a) if the contracting authority has awarded a contract without prior publication of a contract notice in the Official Journal of the European Union without this being permissible in accordance with Directive 2004/18/EC; b) in case of an infringement of Article 1(5), Article 2(3) or Article 2a(2) of this Directive, if this infringement has deprived the tenderer applying for review of the possibility to pursue pre-contractual remedies where such an infringement is combined with an infringement of Directive 2004/18/EC, if that infringement has affected the chances of the tenderer applying for a review to obtain the contract; c) in the cases referred to in the second subparagraph of Article 2b(c) of this Directive, if Member States have invoked the derogation from the standstill period for contracts based on a framework agreement and a dynamic purchasing system. 2. The consequences of a contract being considered ineffective shall be provided for by national law. National law may provide for the retroactive cancellation of all contractual obligations or limit the scope of the cancellation to those obligations which still have to be performed. In the latter case, Member States shall provide for the application of other penalties within the meaning of Article 2e(2). 3. Member States may provide that the review body independent of the contracting authority may not consider a contract ineffective, even though it has been awarded illegally on the grounds mentioned in paragraph 1, if the review body finds, after having examined all relevant aspects, that overriding reasons relating to a general interest require that the effects of the contract should be maintained. In this case, Member States shall provide for alternative penalties within the meaning of Article 2e(2), which shall be applied instead. Economic interests in the effectiveness of the contract may only be considered as overriding reasons if in exceptional circumstances ineffectiveness would lead to disproportionate consequences. However, economic interests directly linked to the contract concerned shall not constitute overriding reasons relating to a general interest. Economic interests directly linked to the contract include, inter alia, the costs resulting from the delay in the execution of the contract, the costs resulting from the launching of a new procurement procedure, the costs resulting from the change of the economic operator performing the contract and the costs of legal obligations resulting from the ineffectiveness. …’

B – Slovak law

1. Law on Public Contracts (‘LPC’)

12. Article 27, entitled ‘Economic and financial standing’, reads: ‘1. Financial and economic standing shall generally be proved by: a) a statement made by a bank or a statement by a branch of a foreign bank, such as a loan commitment by the bank or a branch of a foreign bank, … 3. If the tenderer or competitor, for objective reasons, is not in a position to demonstrate his economic and financial standing by means of financial or economic references, the contracting authority may agree to such proof being provided by means of any other document.’

II – Facts of the dispute and the questions referred for a preliminary ruling

13. The Slovenský futbalový zväz (Slovak Football Federation) issued an invitation to tender ( *5 ) for a contract for ‘restructuring, modernisation and construction of football stadiums’ (‘the contract’), ( *6 ) the object of which was to erect stands in 16 football stadiums (eight of which were category 2, seven category 3 and one category 4). ( *7 )

14. According to the contract notice, candidates were required to provide proof of their economic and financial standing by means of ‘the presentation of a statement made by a bank or a statement by a branch of a foreign bank concerning the grant of credit of a minimum amount of EUR 3000000 for the period of performance of the contract (48 months).’ ( *8 )

15. In particular, the contract notice required a ‘statement by the bank (loan agreement or credit facility agreement) recording the bank’s undertaking to the effect that the tenderer, in the event of acceptance of its tender, will be in a position to provide a guarantee of EUR 3000000 to ensure performance of the contract. The evidence must show that the funds will be available to the tenderer after conclusion of the contract. The evidence must be certified by a person authorised by the bank for that purpose.’

16. The companies INGSTEEL spol. s r.o. and Metrostav, a.s (‘Ingsteel and Metrostav’) participated in the procurement procedure as a group of economic operators. The Regulatory Authority confirmed the rejection of their joint application because it did not satisfy the condition set out in clause III.2.2 of the contract notice.

17. Specifically, the Regulatory Authority did not accept as evidence of the economic and financial standing of Ingsteel and Metrostav the bank declaration confirming that the tender fulfilled all relevant requirements (which also contained information concerning the opening of a current-account credit facility for an amount exceeding EUR 5000000), or the sworn statement given by those companies stating that, if they were awarded the contract, they would have in their account, at the time of conclusion of the contract and throughout the period of performance of the contract, a minimum amount of EUR 3000000.

18. Ingsteel and Metrostav brought an action before the Krajský súd Bratislava (Regional Court, Bratislava, Slovak Republic) seeking annulment of the decision excluding them from the tendering procedure. The action was dismissed by judgment of 13 January 2015.

19. An appeal against the judgment at first instance was brought before the Najvyšší súd (Supreme Court), which has expressed doubts concerning the interpretation of Article 47 of Directive 2004/18, in particular, paragraphs 1(a) and (4) thereof. The Najvyšší súd (Supreme Court) questions whether the Regulatory Authority’s conduct is compatible with those provisions when, on the basis of the documents provided by the tenderer, it took the view that the tenderer had not established that its economic and financial standing satisfied the conditions set out in the contract notice.

20. The Najvyšší súd (Supreme Court) focuses its attention on the necessity of submitting, as evidence of economic and financial standing, a binding undertaking to grant credit and on the refusal to accept a statement by a national bank, formally lodged as such a binding undertaking to grant credit, that makes the grant of that credit conditional on the fulfilment of certain conditions set out in a subsequent contract. The referring court asks whether, in those circumstances, economic and financial standing can be proved by alternative means and whether a sworn statement confirming the existence of a credit arrangement with a bank, for an amount higher than that required in the contract notice, is sufficient.

21. Lastly, the referring court asks whether the fact that the contract has been almost completely performed is an impediment to the grant of the judicial protection required by Directive 89/665, in conjunction with Article 47 of the Charter.

22. The Najvyšší súd (Supreme Court) has therefore referred the following questions to the Court of Justice for a preliminary ruling: ‘(1) May the conduct of a national authority, which finds that a tenderer for a contract with an estimated value of EUR 3 million does not satisfy the selection criterion relating to economic and financial standing, even though a sworn statement submitted by the tenderer and a declaration provided by its bank, certify that it will be able to draw on funds under a secured loan which can be used for any purpose up to a maximum amount exceeding the value of the contract, be considered compatible with the objective of Article 47, in particular Article 47(1)(a) and (4), of 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? (2) Where, in a binding undertaking to grant credit, a bank operating on the banking-services market of a Member State, makes the release of funds conditional upon fulfilment of conditions for granting credit which are not specifically indicated in the loan agreement at the time of the tendering procedure, does such conduct constitute, for the purpose of Article 47(5) of Directive 2004/18, a valid reason why the tenderer cannot produce the references requested by the contracting authority, so that it is possible for the tenderer to prove its economic and financial standing by means of a sworn statement to the effect that its credit arrangement with the bank is sufficient for the purpose in question? (3) In an action for review of the decision of a national authority responsible for public tendering procedures to exclude a tenderer, may the fact that the successful tenderer has almost completed performance of the various contracts be regarded as an objective impediment precluding the national court from giving effect to the provisions of Article 47(1) and (2) of the Charter of Fundamental Rights of the European Union, in conjunction with Article 1(1) and Article 2(3), (6), (7) and (8) of Directive 89/665/EEC of 21 December 1989 on the coordination of laws, regulations and administrative provisions relating to the application of review procedures to the award of public supply and public works contracts?’

III – Proceedings before the Court of Justice

23. The order for reference was received at the Registry of the Court of Justice on 11 February 2016.

24. On 23 March 2016, the Court asked the Najvyšší súd (Supreme Court) to specify the value of the contract at issue in the proceedings. The reply, dated 25 April 2016, stated that the value was EUR 25500000 plus VAT.

25. The Slovak Government and the European Commission lodged written observations. Ingsteel and Metrostav declined to participate in the preliminary-ruling proceedings. It was not considered necessary to hold a hearing.

IV – Summary of the observations of the parties

A – The first question

26. The Slovak Government argues that the statement made by a bank that the tenderers had to provide included a guarantee of more than EUR 3000000 for the whole period of performance of the contract (48 months). The Slovak Government states that, although the wording of Article 47(1) and (4) of Directive 2004/18 does not provide for such a condition, the scheme and aim of the directive support the proposition that the tenderer is required to have available the necessary funds during the period of performance of the contract. That follows, by analogy, from Article 47(2) of that directive, which permits tenderers to rely on the capacities of other entities for performance of the contract.

27. The Slovak Government submits that it is contrary to the principle of effectiveness of the tendering procedure for a tenderer to participate in that procedure if the contracting authority may not require proof of genuine economic and financial standing, in order for performance of the contract to be guaranteed.

28. The Commission contends that Article 47 of Directive 2004/18 relates to the economic and financial standing of the tenderer at the time of award of the contract. However, the tenderer’s economic and financial standing during performance of the contract is governed by Article 26 of that directive, concerning conditions for performance of the contract. At all events, in the light of the wording of the question, the Commission suggests that the condition imposed on the tenderer should be examined under both Article 26 and Article 47 of Directive 2004/18.

29. According to the Commission, Article 26 of Directive 2004/18 provides that the conditions for performance must appear in the contract notice, a requirement fulfilled in this case, and must be compatible with EU law. Citing the case-law of the Court, the Commission argues that, as Directive 2004/18 does not exhaustively govern the special conditions for performance, those conditions may be assessed in accordance with primary EU law.

30. Having considered the difficulty in the light of Article 47 of Directive 2004/18, the Commission, after accepting that the contracting authority has broad discretion, points out that the difficulty lies in the method of providing evidence of economic and financial standing. The Commission questions whether the contract notice expressed clearly the necessity of having available a loan assigned to performance of the contract (which would afford the contracting authority certainty that the financial resources provided by the bank would actually be used for performance of the contract). In its opinion, given that the conditions for participation must be set out so clearly and precisely in the contract notice, a tenderer may not be excluded for failing to provide evidence of the grant of credit assigned to performance of the contract, unless such a requirement was precisely and unequivocally indicated in the contract notice.

B – The second question

31. The Slovak Government states that the group composed of Ingsteel and Metrostav lodged the documents substantiating its economic and financial standing on the date for submission of tenders, but did not prove that it would have funds during the period of performance of the contract, from which it followed that it did not satisfy the conditions of the tender.

32. As regards the question whether a sworn statement is acceptable as a means of proving economic and financial standing in accordance with Article 47(5) of Directive 2004/18, the Slovak Government denies that there were circumstances justifying this, for which purpose it relies on an examination of Slovak banking practice in relation to securing loans allocated for a specific purpose.

33. The Commission cites as sufficient reason for the application of Article 47(5) of Directive 2004/18 the existence of objective facts that cannot be attributed to the tenderer and prevent it from submitting the documents required by the contracting authority to guarantee its economic and financial standing.

C – The third question

34. The Slovak Government takes as its starting-point the fact Directive 89/665 does not provide for review proceedings against decisions on the award of public contracts to have suspensive effect and establishes mechanisms for annulment of the decision to award or formally execute the contract and for the award of damages.

35. The Commission submits that, by the third question, the referring court asks whether performance of the contract, even though the decision to exclude a tenderer has been challenged, is sufficient reason to stay the court proceedings. The Commission contends that Directive 89/665 does not provide a sufficient basis for such a stay.

V – Assessment

A – The first question

36. Although a dividing line, if there is one, cannot easily be drawn between the application, on the one hand, and the interpretation, on the other, of the legal provisions, it is for the referring court to apply its national law (including, in this case, the clauses of the invitation to tender) and for the Court of Justice to provide the national court with an interpretation of Article 47(1)(a) and (4) of Directive 2004/18. It is not the task of the Court of Justice but of the national court to determine whether the documents submitted by Ingsteel and Metrostav as evidence of their economic and financial standing complied with the contract notice.

37. I make that point because, in the first question, the referring court states that the national contracting authority took the view that the tender submitted by Ingsteel and Metrostav did not satisfy one of the criteria in the contract notice. The issue of whether or not that decision was legally correct is a matter which only the national courts can determine. By interpreting Directive 2004/18, the Court of Justice can provide the national courts with certain guidance as to interpretation, but cannot replace those courts for the purposes of carrying out their own tasks, which include that of analysing in detail the documents submitted by the excluded tenderer and establishing whether those documents satisfy the specific terms of the invitation to tender.

38. In accordance with Articles 44 and 47 of Directive 2004/18, in order to verify the suitability of tenderers, they may be asked for minimum levels of economic and financial standing, which they must prove either by means of the references stipulated in the contract notice (Article 47(1) and (4)) or by means of such other documents as the contracting authority considers appropriate (Article 47(5)).

39. In accordance with the Court’s settled case-law, Article 47 of Directive 2004/18 ‘leaves a fair degree of freedom to the contracting authorities’, for, unlike Article 48, it ‘expressly authorises contracting authorities to choose the probative references which must be produced by candidates or tenderers to furnish proof of their economic and financial standing. As Article 44(2) of Directive 2004/18 refers to Article 47, the same freedom of choice exists as regards the minimum levels of economic and financial standing’. ( *9 )

40. Clause III.2.2 of the contract notice required, as evidence of a tenderer’s economic and financial standing, the statement made by a bank concerning the grant of credit for a minimum amount of EUR 3000000 to state that that credit would remain effective ‘for the period of performance of the contract (48 months)’.

41. There is no dispute between the parties regarding the necessary level of economic and financial standing (which is reflected in the amount of the bank credit) or regarding the requirement that it should be proved by means of a document issued by a financial institution. Rather, the dispute concerns the temporal scope of the bank loan required in the contract notice: the credit was to remain available ‘for the period of performance of the contract’, that is, for the 48 months during which the contract was to be performed. Does that specific requirement infringe Articles 44 and 47 of Directive 2004/18? For the reasons I shall set out below, I think not.

42. As I have already observed, the Commission distinguishes the rules laid down in Article 26 from those laid down in Article 47 of Directive 2004/18: the latter is concerned with proof of the economic and financial standing of the tenderer at the time the contract is awarded, whereas Article 26 is appropriate for stipulating the conditions relating to the period of its performance.

43. I do not share that view. Article 26 of Directive 2004/18 focuses on certain special conditions for performance of the contract and applies, in particular, to social and environmental objectives. The wording of recital 33 in the preamble to the directive ( *10 ) is illuminating when it suggests that conditions for performance of the contract ‘may, in particular, be intended to favour on-site vocational training, the employment of people experiencing particular difficulty in achieving integration, the fight against unemployment or the protection of the environment.’

44. However, in requiring certain minimum levels of economic and financial standing, the presumption in Articles 44 and 47 of Directive 2004/18 is that the proof of that standing must refer to the period of performance of the contract. It would not be reasonable to require economic and financial standing only at the time of award of the contract and for the contracting authority not to have the right to request guarantees that the future successful contractor will retain its economic and financial standing during the period of performance of the contract.

45. In my view, it is consistent with that interpretation for Article 47(4) of Directive 2004/18 to permit, as an expression of the broad discretion granted to the contracting authority, the addition to the means of furnishing proof provided for in Article 47(1) of ‘which other references’, and for Article 47(2) to authorise a tenderer to ‘rely on the capacities of other entities’, if it proves to the contracting authority that, with their assistance, it will have the resources to carry out its undertaking.

46. The case-law of the Court provides valuable information about the aim of that legislation. While Directive 92/50/EEC was in force, ( *11 ) the judgment in Holst Italia ( *12 ) stated that ‘the contracting authority is required to verify the suitability of the service providers in accordance with the criteria laid down. That verification is intended, in particular, to enable the contracting authority to ensure that the successful tenderer will indeed be able to use whatever resources it relies on throughout the period covered by the contract.’ That judgment went on to state, in relation to resources resulting from links to other entities that, ‘in order to prove its financial, economic and technical standing with a view to being admitted to participate in a tendering procedure, … it must establish that it actually has available to it the resources of those entities or undertakings which it does not itself own and which are necessary for the performance of the contract’. ( *13 )

47. That finding that economic and financial standing must be assessed as an indicator of suitability for correct performance of the contract remains present in the case-law on the interpretation of Directive 2004/18. In the judgment of 18 October 2012, Édukövízig and Hochtief Solutions, ( *14 ) the Court observed that the aspects chosen by the contracting authority (in that case, aspects of the balance sheets of the undertakings) ‘to establish a minimum level of economic and financial standing must be objectively such as to provide information on such standing of an economic operator and … the threshold thus fixed must be adapted to the size of the contract concerned in that it constitutes objectively a positive indication of the existence of a sufficient economic and financial basis for the performance of that contract’. ( *15 )

48. Lastly, in other cases in which the right for tenderers to rely upon the capacities of third parties was analysed, the Court made that possibility conditional on those tenderers proving to the contracting authority that they would have at their disposal the resources necessary for performance of the contract. ( *16 ) When financial or economic resources are concerned, it is reasonable that these should not be ephemeral but should last until the contractual obligations have been performed.

49. To my mind, Articles 44 and 47 of Directive 2004/18, while enabling contracting authorities to require of tenderers a minimum level of economic and financial standing, also authorise those authorities to require, in the relevant contract notice, the provision of certain evidence establishing a sufficient economic and financial basis for the performance of the contract throughout the period of performance provided for. As I have already stated, the contracting authorities have broad discretion when it comes to giving concrete expression to that requirement.

50. Relying upon that freedom to formulate the conditions governing economic and financial standing and the means of furnishing proof of that standing, I believe that, in this case, the contract awarder was entitled to request the banking documents in the terms set out in clause III.2.2 of the invitation to tender, because: — The amount of credit of up to EUR 3000000 was related and proportionate to the subject-matter of the contract (the overall value of which came to more than EUR 25000000), as stipulated in Article 44(2) of Directive 2004/18. — The period to be covered by that guarantee of economic and financial standing, backed by a bank, was the same as the period of performance of the contract, which, I repeat, is consistent (and reasonable) in the light of the above considerations.

51. Those propositions having been set down, it is for the national court to establish whether, specifically, the documentary evidence furnished by Ingsteel and Metrostav satisfied the terms of the invitation to tender relating to their economic and financial capacity, including the term relating to the temporal scope of the bank credit and the assigning of that credit for performance of the contract throughout the period necessary for the contract to be performed.

B – The second question

52. Article 47(5) of Directive 2004/18 states that ‘[i]f, for any valid reason, the economic operator is unable to provide the references requested by the contracting authority, he may prove his economic and financial standing by any other document which the contracting authority considers appropriate.’

53. The application of that provision to the instant case would make it necessary to establish that Ingsteel and Metrostav were not in a position to accept the ‘normal’ conditions which the contracting authority had stipulated for providing proof of their economic and financial standing. That would be the case if, in Slovakia, a tenderer was unable to obtain from a financial institution credit linked to performance of the contract in accordance with the requirements of clause III.2.2 of the contract notice.

54. In those circumstances, the referring court asks whether a sworn statement by the tenderer stating that, if it were awarded the works contract, it would have available in its account a minimum amount of EUR 3000000, corresponding to the amount of credit required, both when the contract was concluded with the contract awarder and throughout the period of performance of the contract, is valid.

55. Application of Article 47(5) of the directive means, first, that the economic operator is unable to obtain the references requested by the contracting authority. Second, it means that that inability is due to a ‘valid reason’. Only if both criteria are satisfied can recourse be had to other means of proving economic and financial standing.

56. In the instant case, therefore, the ‘objective’ impossibility ( *17 ) of obtaining from a bank credit assigned to performance of the contract, throughout the period of performance of the contract, would have to be established. This is purely a finding of fact that must be made by the national court. That court must examine whether banking practice in Slovakia precludes undertakings bidding for contracts, like Ingsteel and Metrostav, from obtaining a statement made by a bank in the terms set out in the contract documents. ( *18 )

57. If the solution reached by the referring court is that in that country such an undertaking by a bank can be obtained, the argument in support of the application of Article 47(5) of Directive 2004/18 would simply not exist.

58. If, on the other hand, such an undertaking by a bank cannot be obtained, it will be possible to move on to the assessment of the alternative evidence of its economic and financial standing furnished by the tenderer. However, inability to provide the references required in the contract documents must be examined from an objective point of view: the mere fact that, owing to particular circumstances characterised specifically by a lack of economic resources, the tenderers could not obtain credit from a bank in accordance with the terms of the contract documents will not be a ‘valid reason’.

59. According to the order for reference, the tenderer provided, as an alternative reference, the sworn statement to which I referred above. The validity of that self-declaration of economic and financial standing must be examined, first, by the contracting authority, for it is that authority that, under Article 47(5), in fine, of Directive 2004/18, has the power to examine whether the document is ‘appropriate’ for that task.

60. The decision not to accept that document may, as is logical, be challenged before the national court which, in turn, must examine the grounds and the reasoning for the decision when determining whether the contracting authority exceeded the discretion granted to it by Article 47(5), in fine, to ‘[consider] appropriate’ the alternative proof submitted by the tenderer. Again, the Court may not replace the national court for the purpose of making that decision, which is closely connected to factual elements, or for the purpose of determining whether the sworn statement of the tenderer is, in a specific situation, a sufficient economic and financial guarantee for performance of the contract.

C – The third question

61. I agree with the Slovak Government that there is a certain lack of clarity in the third question referred by the Najvyšší súd (Supreme Court), in terms both of the facts it describes and of its content.

62. As regards the facts, the referring court transcribes, first, the view of the Regulatory Authority to the effect that the situation was ‘irreversible, and cannot be changed even in the event of a decision reviewing the award of the contract by the Board of the regulatory authority’ because performance of the contracts was already under way. ( *19 ) Second, the order accepts, as a premiss for the question referred for a preliminary ruling, the hypothesis that ‘the object of the initial administrative action, that is to say, taking part in the public procurement contract, has ceased to exist, and the tendering procedure cannot be relaunched because the contract has been performed by the successful tenderer.’

63. Following that approach, the referring court appears to ask, in short, whether, under Article 47 of the Charter, in conjunction with Article 1(1) and Article 2(3), (6), (7) and (8) of Directive 89/665, the fact that the performance of the contract has almost been completed is an impediment preventing the excluded tenderer from bringing the relevant action (review proceedings) against the award decision, including seeking annulment of that decision.

64. The articles of Directive 89/665 transcribed by the referring court are from its original version, no longer in force when the invitation to tender was issued (16 November 2013). Accordingly, the references to legislation must be brought into line with the consolidated text following the entry into force of the amendments introduced by Directive 2007/66. ( *20 )

65. In the Opinion in Connexxion Taxi Services, ( *21 ) I pointed out that ‘[w]ith regard to the decisions of contracting authorities (in so far as they concern, obviously, contracts falling within the scope of Directive 2004/18), Member States must ensure that the persons concerned have available review mechanisms suitable for determining, quickly and effectively, whether they have infringed EU law on public procurement or national rules transposing EU law into their respective legal systems. That is, ultimately, the purpose of Directive 89/665.’

66. With that general aim, Article 2 of Directive 89/665 provides for two different procedural situations: (a) interlocutory proceedings enabling interim measures to be adopted in the period before the contract is concluded, and (b) the other types of review procedure, aimed at securing annulment of the administrative act awarding the contract and, where appropriate, the award of damages; the order for reference refers only to the latter.

67. The action brought by Ingsteel and Metrostav before the Slovak courts being an action for annulment of the decision, if they should be successful in their claims that would, in principle, mean that the decision awarding the contract would be declared null and void. ( *22 ) However, the referring court assumes ( *23 ) that annulment would not, in practice, lead to retroaction of the procedure so that the situation created could be reversed.

68. As Article 2(4) of Directive 89/665 provides that a review procedure does not have automatic suspensive effect, it is logical that the directive should provide for the possibility that an action for annulment can be brought in relation to a contract which is either being performed or has already been performed.

69. In fact, Directive 89/665 does not provide for an unequivocal solution in that regard. In some cases (Articles 2d to 2f) the rules laid down in the directive are applied, ( *24 ) which even provide that national review bodies may not consider a contract ineffective, even though it has been awarded illegally, if there are overriding reasons relating to a general interest requiring the effects of the contract to be maintained, without prejudice to the imposition of the appropriate penalties and the award of damages. ( *25 ) However, in other cases (Article 2(7) of the directive), it is the rules of national law that determine the effect that review procedures are to have on concluded contracts.

70. Within that range of possibilities which the referring court (or the review body at first instance) will have to consider, it would be unacceptable for the de facto situation regarding the performance of the contract to be treated as an insurmountable obstacle to determining whether the decision excluding the tenderer was lawful. Whatever the procedural solution may be that is most compatible with Directive 89/665 (and with the national law transposing that directive), and its practical consequences for the effects of the contract, the appellants still have an interest in obtaining the appropriate judgment, at least with a view to obtaining damages, if their action is successful, for the loss and harm suffered as a result of having been unlawfully excluded from the selection process.

71. Once again, it is for the national court to assess the consequences of the possible annulment of the decision for the award of the contract concluded.

VI – Conclusion

72. In the light of the arguments set out, I propose that the Court reply as follows to the questions referred by the Najvyšší súd Slovenskej republiky (Supreme Court of the Slovak Republic): (1) Article 47, in particular Article 47(1)(a) and (4), of 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, does not preclude including in a contract notice, as selection criteria relating to economic and financial standing, the criteria included in the contract notice giving rise to the main proceedings. It is for the national court to establish whether the excluded tenderers satisfied those criteria. (2) It is for the referring court to determine whether there was a “valid reason”, for the purposes of Article 47(5) of Directive 2004/18/EC, precluding a tenderer from providing the references requested by the contracting authority. If that should be the case, the referring court must also determine whether, in accordance with Slovak law, a sworn statement by the tenderer concerning its economic and financial standing is acceptable as an appropriate economic and financial guarantee. (3) The fact that the successful tenderer has almost completed performance of the contract does not prevent the excluded tenderers bringing the appropriate proceedings, in accordance with the first and second paragraphs of Article 47 of the Charter of Fundamental Rights of the European Union, in conjunction with Articles 1 and 2 of Directive 89/665/EEC of 21 December 1989 on the coordination of laws, regulations and administrative provisions relating to the application of review procedures to the award of public supply and public works contracts.

( *22 ) In the Opinion in Prezes Urzędu Komunikacji Elektronicznej and Petrotel, C‑231/15, EU:C:2016:440, points 62 to 69, I stated that, as a general rule, the annulment of an administrative decision leads to the creation of retroactive effects so that, in the absence of an interim measure suspending the effectiveness of that decision, the invalidity of the administrative decision entails the obligation to undo, from the outset, its effects. However, that general rule is open to a number of exceptions which are not unknown in EU law, and I mentioned specifically the scope of the award of public contracts and the review system introduced into Directive 89/665 by Directive 2007/66.

( *23 ) As transcribed in paragraph 23 of the order for reference, the Regulatory Authority stated that ‘once the decision of the regulatory authority on the complaint became final, the contract awarder decided to resume the tendering procedure’.
