Charter of Fundamental Rights of the European Union (‘the Charter’), in the light 
of the scope of judicial review with regard to whether an abnormally low tender 
has been submitted in a procedure to award a public contract. 
Questions referred for a preliminary ruling 
The referring court hereby refers the following questions for a preliminary ruling: 
‘1. Is Article 56 of Directive [2014/24] in conjunction with Article 69 thereof, 
or, respectively, Article 38 of Directive [2009/81] in conjunction with Article 49 
thereof, to be interpreted as meaning that a contracting authority, where it is 
objectively impossible to apply the criterion laid down in national law for the 
evaluation of an abnormally low tender and in the absence of a different criterion 
selected by the contracting authority and announced in advance, is not required to 
verify whether an abnormally low tender exists? 
2. Is Article 56 of Directive 2014/24 in conjunction with Article 69 thereof, or, 
respectively, Article 38 of Directive 2009/81 in conjunction with Article 49 
thereof, to be interpreted as meaning that the contracting authority is required to 
verify whether abnormally low tenders exist only if there is a suspicion regarding 
any tender; or, conversely, is the contracting authority required to always ensure 
that the received tenders are genuine, and state the relevant reasons? 
3. Does such a requirement apply to the contracting authority if only two 
tenders have been received during the procedure for the award of a public 
contract?  
4. Is Article 47 of the [Charter] to be interpreted as meaning that the 
contracting authority’s assessment as regards a lack of suspicion that an 
abnormally low tender exists, or, respectively, that contracting authority’s 
conviction that the first-ranked tenderer has submitted a genuine tender, is subject 
to judicial review? 
5. Should the previous question be answered in the affirmative: Is Article 47 of 
the [Charter] to be interpreted as meaning that a contracting authority in a 
procedure for the award of a public contract which has not verified whether an 
abnormally low tender exists is required to provide justification and reasons as to 
why there is no suspicion that an abnormally low tender has been submitted, in 
other words, that the first-ranked tender is genuine?’

SUMMARY OF A REQUEST FOR A PRELIMINARY RULING – CASE C-669/20 
 
4  
Succinct presentation of the facts and procedure in the main proceedings 
1 With Decision No 5785mpr-58/15.08.2019, the Deputy Minister for the Interior of 
the Republic of Bulgaria initiated a ‘restricted’ procedure for the award of a public 
contract, the subject of which was the ‘planning, establishment, and management 
of a Generation 2019 system for the issue of Bulgarian identity documents’. The 
contract notice no 158-363493 was published in the Official Journal of the 
European Union (2018/S). 
2 Ordinance No 5785mpz-106/16.10.2018 appointed an auxiliary commission 
whose task was to pre-select candidates and to examine, evaluate, and rank the 
tenders. 
3 With Decision No 5785mpr-40/03.07.2019, following this pre-selection, the 
names of the candidates to be asked to submit a tender were published, namely 
Veridos GmbH and the consortium Mühlbauer ID Services GmbH – S&T. 
4 Following an evaluation of the submitted tenders and with Decision No 5785-
mpr-35/29.04.2020 of the Deputy Minister for the Interior of the Republic of 
Bulgaria, the consortium Mühlbauer ID Services GmbH – S&T was awarded the 
public contract, and Veridos GmbH was ranked in second place.  
5 Veridos GmbH filed a complaint regarding the abovementioned Decision 
No 5785-mpr-35/29.04.2020 of the Deputy Minister for the Interior of the 
Republic of Bulgaria with the Komisiya za zashtita na konkurentsiyata (the 
Bulgarian Commission for Protection of Competition), as a result of which 
proceedings with reference number KZK-308/2020 were opened.  
6 With Decision No 510 of 25 June 2020, the Bulgarian Commission for Protection 
of Competition dismissed the complaint of Veridos GmbH with reference number 
KZK-308/2020. 
7 On 13 July 2020, Veridos GmbH filed an appeal on a point of law against the 
abovementioned decision of the Bulgarian Commission for Protection of 
Competition; legal proceedings were opened before the Varhoven administrativen 
sad (Supreme Administrative Court, Bulgaria) while observing the requirements 
to protect classified information. 
Succinct presentation of the reasoning in the request for a preliminary ruling 
8 The necessity for a reference for a preliminary ruling in this case emerges within 
the scope of assessing whether the contracting authority is required, in the light of 
the principles of EU law (transparency, non-discrimination and equal treatment), 
to carry out an evaluation of whether an abnormally low tender exists, in order to 
ensure an objective comparison of the tenders and to determine, under genuine 
competitive conditions, which tender is the most economically advantageous, 
without it being abnormally advantageous such as to distort competition.

9 In determining the legal framework that applies to the legal dispute, the referring 
court notes that the contract includes elements that fall under the scope of 
application of Directive 2014/24; however, the contracting authority took the 
decision and gave notice of a single contract in accordance with Directive 
2009/81. The identical content and analogous function of the relevant provisions 
of the two directives imply an analogous interpretation, in the referring court’s 
view. 
10 The legal dispute concerns the powers of the national legislature to regulate the 
criterion for evaluating an abnormally advantageous tender that it has exercised by 
means of enacting Article 72(1) of the Zakon za obshtestvenite porachki (Law on 
public procurement). That article provides for a criterion for the evaluation of an 
abnormally advantageous tender, namely the requirement that it is ‘20% lower 
than the mean value of the tenders submitted by the other tenderers in respect of 
the same evaluation factor’. In this way, the legislature implicitly requires that 
there are at least three tenders, whereby one tender is assessed against the mean 
value of the other two tenders.  
11 The decision at first instance in this legal dispute, namely that of the Bulgarian 
Commission for Protection of Competition, that the provision in Article 72(1) of 
the national Zakon za obshtestvenite porachki (Law on public procurement) 
cannot be applied, must be considered in this very context, since, in the present 
case, only two tenders were submitted and the mean value provided for by the 
legislature to ascertain whether abnormally advantageous tenders exist cannot be 
calculated. 
12 The contracting authority in the case at hand – the Ministry of the Interior – did 
not work out details for nor announce in advance any algorithm for assessing and 
analysing whether an abnormally advantageous tender exists, so as to allow the 
Varhoven administrativen sad (Supreme Administrative Court, Bulgaria) to assess 
that algorithm in the light of EU law, if there are grounds to assume that 
Articles 56 and 69 of Directive 2014/14, or, respectively, Articles 38 and 49 of 
Directive 2009/81, contain a sufficiently clear and unconditional standard of 
conduct – an obligation to carry out an evaluation.  
13 In this respect and in the light of the specific circumstances of this legal dispute, 
an assessment is a priori impossible, and the abovementioned provisions of EU 
law remain disapplied. 
14 The case-law of the Court of Justice of the European Union and of the General 
Court of which the referring court is aware, including proceedings concerning 
challenges of legal acts of institutions of the European Union in the latter’s 
capacity of contracting authority, is presented in the above list of judgments in the 
present summary. The referring court makes particular reference to the cases that 
formed the basis for the following judgments: 
15 Judgment of 29 March 2012, SAG ELV Slovensko and Others, С-599/10: 
SUMMARY OF A REQUEST FOR A PRELIMINARY RULING – CASE C-669/20

– the European Union legislature intended to require the awarding authority to 
examine the details of tenders which are abnormally low, and for that purpose 
obliges it to request the tenderer to furnish the necessary explanations to prove 
that those tenders are genuine (paragraph 28); 
– Article 55(1) of Directive 2004/18 requires the contracting authority to set out 
clearly the request sent to the tenderers concerned so that they are in a position 
fully and effectively to show that their tenders are genuine (paragraph 31). 
– Article 55 of Directive 2004/18, far from precluding a provision of national 
legislation, which, in essence, provides that if a tenderer offers an abnormally 
low price, the contracting authority must ask it in writing to clarify its price 
proposal, requires the inclusion of such a provision in the national legislation 
on public procurement (paragraph 33). 
16 Judgment of 4 July 2017, European Dynamics Luxembourg and Others, 
T-392/15: 
– compliance with the duty to state reasons must, in principle, be determined in 
accordance with the information available to the applicants, at the latest, when 
the action was brought. The reasons for a decision cannot be explained for the 
first time ex post facto before the Court. Only exceptional circumstances may 
justify the Court taking into consideration evidence adduced in the course of 
the proceedings (paragraph 74).  
– the abnormally low nature of a tender must be assessed by reference to the 
composition of the tender and the services at issue (paragraph 83). 
– the contracting authority’s obligation to check the seriousness of a tender arises 
where there are doubts beforehand as to its reliability, bearing in mind that the 
main purpose of that article is to enable a tenderer not to be excluded from the 
procedure without having had an opportunity to explain the terms of its tender 
which appears abnormally low. Thus, it is only where such doubts exist that the 
evaluation committee is required to request relevant information on the 
composition of the tender, before, if necessary, rejecting it. However, if a 
tender does not appear abnormally low under Article 158(4) of the 
Implementing Regulation, that article does not apply (paragraph 85); 
– in the first stage, the contracting authority need only determine whether the 
tenders submitted contain evidence likely to arouse suspicion that they might 
be abnormally low. That is the case in particular, where the price proposed in a 
tender submitted is considerably less than that of the other tenders submitted or 
the normal market price. If the tenders submitted do not contain such evidence 
and therefore, do not appear to be abnormally low, the contracting authority 
may continue the evaluation of that tender and the award procedure for the 
contract (paragraph 88). 
VERIDOS

– however, if there is evidence which arouses suspicion that a tender may be 
abnormally low, the contracting authority must, in the second stage, check the 
composition of the tender in order to ensure that it is not abnormally low. 
Where it carries out that check, the contracting authority must give the tenderer 
which submitted that bid the opportunity to set out the reasons why it considers 
its tender is not abnormally low (paragraph 89). 
17 judgment of 28 January 2016, Agriconsulting Europe, T-570/13: 
– the contracting authority may, in the course of its examination of the 
abnormally low nature of a tender, take into consideration all the factors that 
are relevant in the light of the services at issue (paragraph 55); 
– the existence of a proper exchange of views, at an appropriate time in the 
procedure for examining tenders, between the contracting authority and the 
tenderer, to enable the latter to demonstrate that its tender is genuine, 
constitutes a fundamental requirement in the award of public contracts 
(paragraph 71). 
18 judgment of 18 December 2014, Data Medical Service, C-568/13: 
– it is for the Member States and, in particular, the contracting authorities to 
determine the method of calculating an anomaly threshold constituting an 
‘abnormally low tender’ (paragraph 49); 
– the abnormally low character of a tender must be assessed ‘in relation to the 
service to be provided’. Thus, the contracting authority may take into 
consideration all the factors that are relevant in the light of the service at issue 
(paragraph 50). 
19 judgment of 4 May 2017, Esaprojekt, C-387/14, EU:C:2017:338: 
– the bids of all tenderers must be subject to the same conditions; all the 
conditions and detailed rules of the award procedure must be drawn up in a 
clear, precise and unequivocal manner in the contract notice or tender 
specifications so that all tenderers can understand their exact significance and 
interpret them in the same way and the contracting authority is able to ascertain 
whether the tenders submitted satisfy the criteria applying to the contract in 
question (paragraph 36).  
20 The referring court notes that the European Commission, in its ‘Guidance on the 
participation of third-country bidders and goods in the EU procurement market’, 
states that Member States are free to set up national rules or methods to be used 
for identifying tenders that are suspected of being abnormally low, provided that 
these rules are objective and non-discriminatory. Moreover, in case national law 
has not set up a method, contracting authorities themselves can establish 
transparent and non-discriminatory methods. The European Commission also 
stated that offers may appear to be abnormally low in relation to any of the 
SUMMARY OF A REQUEST FOR A PRELIMINARY RULING – CASE C-669/20 
 
8  
relevant parameters and award criteria. This may be the case, for example, if the 
relationship between the quality offered and the price is suspicious. As is clear 
from that communication, the contracting authority is under a legal obligation to 
request an explanation of the price offered. 
21 The inclinations of the referring court’s deliberations in relation to the decision in 
this legal dispute and possible answers to the questions referred are presented 
below. 
22 In accordance with the principle established in the Bulgarian Administrativno-
protsesualen kodeks (Code of Administrative Procedure), the absence of 
justification in respect of the decisive activity of the administrative authority 
constitutes a procedural defect of the administrative act, which precludes the 
possibility of defending the rights and interests of the parties concerned, as well as 
effective judicial review. The Court of Justice and the General Court have 
analogously made reference to the existence of similar principles in relation to the 
activity of EU institutions (judgments of 20 September 2011, Evropaïki Dynamiki, 
T-461/08, EU:C:2011:494, paragraph 100, and of 4 June 2013, ZZ, C-300/11, 
EU:C:2013:363, paragraph 53). 
23 In the light of the circumstances in the present case, it must be concluded that the 
national contracting authority does not have any evaluation criterion other than 
that in Article 72 of the national Zakon za obshtestvenite porachki (Law on public 
procurement (ZOP)). 
24 The term ‘mean value’ within the meaning of Article 72(1) of the national Zakon 
za obshtestvenite porachki (Law on public procurement) is a term that is not used 
as a criterion in EU law. It was introduced independently by the national 
legislature and is intended as a sub-criterion to clarify the term ‘abnormally low 
tender’ that is used in EU law. By doing so, the national legislature has implicitly 
introduced the requirement that three tenders are submitted.  
25 Article 56 of Directive 2014/24, and, respectively, Article 38 of Directive 
2009/81, set out for their part a legal principle that requires additional clarification 
as to how it is expressed and what conditions must be fulfilled in order to permit 
deviation from it or for it to be disapplied. 
26 Article 69 of Directive 2014/24 uses the term ‘abnormally low tender’, while the 
wording of Article 49 of Directive 2009/81 makes reference to ‘abnormally low 
tenders’, which implies some discretion in the choice of evaluation criteria, 
whether at a legislative level or by the contracting authority in question, in so far 
as the criterion is objective and is announced in advance. For its part, the national 
Zakon za obshtestvenite porachki (Law on procurement) circumscribes the powers 
by linking the term ‘abnormally advantageous tender’ to the criterion of the ‘mean 
value of the tenders’ and therefore implicitly also to the requirement for three 
tenders; this raises the question of whether it considerably restricts or limits the 
means of achieving the imperative and objective of the directive.

27 At the same time, even though Article 56 of Directive 2014/24, and, respectively, 
Article 38 of Directive 2009/81, have the character of a legal principle, it follows 
from the wording of Article 69 of Directive 2014/24 and Article 49 of Directive 
2009/81 that the assessment as to whether an abnormally low tender exists 
becomes mandatory if the tenders appear to be abnormally low. This particular 
wording requires an interpretation as to whether this assessment is a subjective 
option or whether it always has an objective nature, and, being a principle, 
whether it must be justified in the contracting authority’s decision on the ranking 
of tenderers. 
28 Next, it must be clarified, by means of interpretation, whether this requirement is 
only applicable if the contracting authority intends to reject an abnormally low 
tender, or whether carrying out an evaluation as to whether an abnormally low 
tender exists is of importance for the lawful conduct of the procedure and as such 
applies always. This is all the more relevant in the light of the present case, where 
only two tenders have been submitted and the second-ranked tenderer’s main 
objection is that an abnormally low tender has been submitted by the successful 
tenderer. 
29 In the alternative, if the contracting authority has not undertaken any evaluation as 
to whether an abnormally low tender exists, which implies a presumption that 
there is no suspicion, must the contracting authority provide justification in its 
decision on the ranking of candidates as to why there was no suspicion that the 
first-ranked tender may be an abnormally low tender? In other words, why it 
considers the submitted tenders to be genuine in accordance with Article 69 of 
Directive 2014/24, or, respectively, Article 49 of Directive 2009/81, so that the 
presumption of no suspicion can be subjected to judicial review. 
30 The existence of a criterion that is laid down in law but cannot be applied in 
practice, and the absence of a different criterion announced beforehand 
concerning the identification of abnormally low tenders, raise the question of 
whether the contracting authority is released from the requirement to undertake an 
evaluation of whether an abnormally low tender exists, given that the Court of 
Justice has expressly ruled in its case-law that the contracting authority must 
ensure that the submitted tenders are genuine. 
31 Is the contracting authority consequently required to always provide reasons in 
relation to the existence of an abnormally low tender, or can it defend its decision 
on the ranking of tenderers when it becomes a party to proceedings in which its 
decision is challenged in court, when it would do so by providing substantive 
arguments to be evaluated by the court? This question must be examined from the 
perspective of the case-law of the Court of Justice of the European Union, in 
which that court has consistently expressed the view that the reasons can be 
presented as part of proceedings to challenge the legal act only under exceptional 
circumstances. 
SUMMARY OF A REQUEST FOR A PRELIMINARY RULING – CASE C-669/20

32 Next, the absence of any definition of the term ‘abnormally low tender’ in the 
directive in conjunction with the term ‘appear to be’ used in relation to tenderers’ 
tenders creates a condition for the unequal treatment of economic operators by the 
various contracting authorities within the European Union. 
33 Since the existence of a ‘suspicion’ constitutes an internal, subjective element that 
forms part of the cognitive-analytical activity of the contracting authority or 
auxiliary authority in respect of the procedure for the award for a public contract, 
this raises the question, as far as the referring court is concerned, of whether the 
absence of any suspicion as to whether the tender is genuine must be duly justified 
by the contracting authority, in order to enable a judicial review. 
34 As their content shows, Article 69 of Directive 2014/24 and, respectively, 
Article 49 of Directive 2009/81, concern the contracting authority and impose 
specific obligations on it under certain circumstances. On the other hand, 
Article 56 of Directive 2014/24 and Article 38 of Directive 2009/81 contain a 
provision the purpose of which is to protect; in other words, it is intended to 
guarantee the lawful conduct of the procedure for the award of a public contract. 
The role of ensuring lawfulness for the purposes of the directive belongs, in fact, 
primarily and in the first place, to the contracting authority.  
35 The requirement of an effective judicial review implies for its part that all relevant 
aspects of the procedure can be duly contested by the parties, and evaluated and 
analysed by the court. 
36 If the reverse conclusion were to be drawn, it should be assumed that the absence 
of any suspicion as to whether a particular tender is genuine represents an 
irrebuttable presumption that forms an implicit part of the contracting authority’s 
decision in favour of a successful tenderer, without requiring reasons and 
justification for the legal act in that regard, and without allowing that presumption 
to be rebutted in a subsequent judicial review. However, such an outcome also 
does not categorically follow from the provisions of the directive and the case-law 
of the Court of Justice. 
37 The answers to the questions summarised above are not unequivocally apparent 
from the applicable legal basis of EU law. In the absence of any case-law of the 
Court of Justice of the European Union on a similar case, the referring court 
hereby refers the abovementioned questions to the Court of Justice for a 
preliminary ruling.
