| 13 | The Tribunale amministrativo regionale per il Lazio (Regional Administrative Court, Lazio, Italy) observes that, in its judgment of 2 June 2016, Pizzo (C‐27/15, EU:C:2016:404), and its order of 10 November 2016, Edra Costruzioni and Edilfac (C‐140/16, not published, EU:C:2016:868), the Court of Justice ruled on whether participants may be excluded from a public procurement procedure for failing to specify the costs relating to safety and security at work and whether such an omission can be regularised subsequently. On that occasion, the Court stated that, in a situation where a condition for participating in a procurement procedure, on pain of the tenderer being excluded, is not expressly laid down in the contract documentation and that condition can be identified only by a judicial interpretation of national law, the contracting authority may grant the excluded tenderer a sufficient period in order to regularise its situation. |

| 15 | The Tribunale amministrativo regionale per il Lazio (Regional Administrative Court, Lazio) entertains doubts as to whether the national legislation at issue in the main proceedings is compatible with the general principles of protection of legitimate expectations, legal certainty and proportionality, in particular where, as in the case before it, the financial tender, which does not contain a statement of labour costs, was drawn up by the undertaking participating in the tender procedure in conformity with the documentation devised for that purpose by the contracting authority, and where the substantive compliance with the rules on labour costs is not in doubt. |

| 17 | In those circumstances the Tribunale amministrativo regionale per il Lazio (Regional Administrative Court, Lazio) decided to stay the proceedings and refer the following question to the Court of Justice for a preliminary ruling:
  ‘Do the [EU] principles of the protection of legitimate expectations and legal certainty, together with the principles of the free movement of goods, the freedom of establishment and the freedom to provide services, laid down in the [FEU Treaty], as well as the principles deriving therefrom, such as equality of treatment, non-discrimination, mutual recognition, proportionality and transparency, referred to in Directive [2014/24], preclude the application of national legislation, such as the Italian legislation founded on the combined provisions of [Article 95(10) and Article 83(9) of the Code of Public Contracts], according to which the failure to list the labour costs separately in the financial tender in a procedure for the award of public services inevitably results in the exclusion of the tendering undertaking concerned without the possibility of supplementing or amending its tendering documentation [‘soccorso istruttorio’], even where the obligation to list those costs separately was not set out in the tender documents, and even though, in substantive terms, the tender in question actually took into account the minimum labour costs, in accordance, moreover, with a declaration for that purpose made by the tenderer?’ |

Consideration of the question referred

Consideration of the question referred

| 18 | By its question, the referring court asks, in essence, whether the principles of legal certainty, equal treatment and transparency, to which Directive 2014/24 refers, must be interpreted as precluding national legislation, such as that at issue in the main proceedings, according to which failure to list the labour costs separately, in a financial tender submitted in a procedure for the award of public services, results in that tender being excluded without the possibility of supplementing or amending the tendering documentation, even where the obligation to list those costs separately was not set out in the tender documents. |

By its question, the referring court asks, in essence, whether the principles of legal certainty, equal treatment and transparency, to which Directive 2014/24 refers, must be interpreted as precluding national legislation, such as that at issue in the main proceedings, according to which failure to list the labour costs separately, in a financial tender submitted in a procedure for the award of public services, results in that tender being excluded without the possibility of supplementing or amending the tendering documentation, even where the obligation to list those costs separately was not set out in the tender documents.

| 19 | In that regard, it is settled case-law of the Court that, first, the principle of equal treatment requires tenderers to be afforded equality of opportunity when formulating their tenders, which therefore implies that the tenders of all tenderers must be subject to the same conditions. Secondly, the obligation of transparency, which is its corollary, is intended to preclude any risk of favouritism or arbitrariness on the part of the contracting authority. That obligation implies that 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 specifications so that, first, all reasonably informed tenderers exercising ordinary care can understand their exact significance and interpret them in the same way and, secondly, the contracting authority is able to ascertain whether the tenders submitted satisfy the criteria applying to the contract in question (judgment of 2 June 2016, Pizzo, C‐27/15, EU:C:2016:404, paragraph 36 and the case-law cited). |

In that regard, it is settled case-law of the Court that, first, the principle of equal treatment requires tenderers to be afforded equality of opportunity when formulating their tenders, which therefore implies that the tenders of all tenderers must be subject to the same conditions. Secondly, the obligation of transparency, which is its corollary, is intended to preclude any risk of favouritism or arbitrariness on the part of the contracting authority.

| 20 | In the light of those considerations, the Court has held that the principle of equal treatment and the obligation of transparency must be interpreted as precluding an economic operator from being excluded from a procedure for the award of a public contract as a result of that economic operator’s non-compliance with an obligation which does not expressly arise from the documents relating to that procedure or out of the national law in force, but from an interpretation of that law and those documents and from the incorporation of provisions into those documents by the national authorities or administrative courts (judgment of 2 June 2016, Pizzo, C‐27/15, EU:C:2016:404, paragraph 51; see, to that effect, order of 10 November 2016, Spinosa Costruzioni Generali and Melfi, C‐162/16, not published, EU:C:2016:870, paragraph 32). |

| 21 | By contrast, those same principles do not, as a rule, preclude an economic operator from being excluded from a procedure for the award of a public contract because it has failed to comply with an obligation that is expressly imposed — on pain of the operator’s being excluded — by the documents relating to that procedure or provisions of national law in force. |

By contrast, those same principles do not, as a rule, preclude an economic operator from being excluded from a procedure for the award of a public contract because it has failed to comply with an obligation that is expressly imposed — on pain of the operator’s being excluded — by the documents relating to that procedure or provisions of national law in force.

| 22 | The foregoing applies all the more since, according to the settled case-law of the Court, where obligations were clearly imposed in the documents relating to the public procurement procedure — on pain of the operator’s being excluded — the contracting authority cannot accept any rectification whatsoever of failures to comply with those obligations (see, by analogy, judgments of 6 November 2014, Cartiera dell’Adda, C‐42/13, EU:C:2014:2345, paragraphs 46 and 48; of 2 June 2016, Pizzo, C‐27/15, EU:C:2016:404, paragraph 49; and of 10 November 2016, Ciclat, C‐199/15, EU:C:2016:853, paragraph 30). |

The foregoing applies all the more since, according to the settled case-law of the Court, where obligations were clearly imposed in the documents relating to the public procurement procedure — on pain of the operator’s being excluded — the contracting authority cannot accept any rectification whatsoever of failures to comply with those obligations (see, by analogy, judgments of 6 November 2014, Cartiera dell’Adda, C‐42/13, EU:C:2014:2345, paragraphs 46 and 48; of 2 June 2016, Pizzo, C‐27/15, EU:C:2016:404, paragraph 49; and of 10 November 2016, Ciclat, C‐199/15, EU:C:2016:853, paragraph 30).

| 23 | It should be added in that respect that under Article 56(3) of Directive 2014/24 Member States may restrict the situations in which the contracting authorities can request the economic operators concerned to submit, supplement, clarify or complete the supposedly incomplete, incorrect or missing information or documentation within an appropriate time limit. |

| 24 | Lastly, in accordance with the principle of proportionality, which is a general principle of EU law, since the purpose of national legislation relating to public procurement procedures is to safeguard the equal treatment of tenderers, such legislation must not go beyond what is necessary to achieve the intended objective (see, to that effect, judgment of 8 February 2018, Lloyd’s of London, C‐144/17, EU:C:2018:78, paragraph 32 and the case-law cited). |

| 25 | In the present case, it is apparent from the information provided by the referring court that the obligation, on pain of an operator’s being excluded, to list labour costs separately, is clearly apparent from reading Article 95(10) of the Code of Public Contracts in conjunction with Article 83(9) of that code, in force when the contract notice at issue in the main proceedings was published. On the basis of Article 56(3) of Directive 2014/24, the Italian legislature decided to exclude, in Article 83(9) of that code, use of the soccorso istruttorio procedure where, in particular, the missing information relates to labour costs. |

| 26 | Furthermore, although the referring court states that the contract notice at issue in the main proceedings did not expressly refer to the obligation on potential tenderers, under Article 95(10) of the Code of Public Contracts, to list their labour costs in the financial tender, it is nonetheless apparent from the information in the file available to the Court that the contract notice stated that ‘the rules of the [Code of Public Contracts shall apply] to matters not expressly provided for in this notice and the tender documents and specifications’. |

Furthermore, although the referring court states that the contract notice at issue in the main proceedings did not expressly refer to the obligation on potential tenderers, under Article 95(10) of the Code of Public Contracts, to list their labour costs in the financial tender, it is nonetheless apparent from the information in the file available to the Court that the contract notice stated that ‘the rules of the [Code of Public Contracts shall apply] to matters not expressly provided for in this notice and the tender documents and specifications’.

| 27 | It follows that any reasonably informed tenderer exercising ordinary care was, as a rule, in a position to be aware of the relevant rules applicable to the tender procedure at issue in the main proceedings, including the obligation to list labour costs in the financial tender. |

It follows that any reasonably informed tenderer exercising ordinary care was, as a rule, in a position to be aware of the relevant rules applicable to the tender procedure at issue in the main proceedings, including the obligation to list labour costs in the financial tender.

| 28 | In those circumstances, the principles of equal treatment and transparency do not preclude national legislation, such as that at issue in the main proceedings, according to which the absence of a statement of labour costs causes the tenderer concerned to be excluded with no opportunity to use the soccorso istruttorio procedure, even where the contract notice did not expressly refer to the statutory obligation to provide that statement. |

In those circumstances, the principles of equal treatment and transparency do not preclude national legislation, such as that at issue in the main proceedings, according to which the absence of a statement of labour costs causes the tenderer concerned to be excluded with no opportunity to use the soccorso istruttorio procedure, even where the contract notice did not expressly refer to the statutory obligation to provide that statement.

soccorso istruttorio

| 29 | Nevertheless, it is apparent from Gea’s written observations to the Court that it was not physically possible for the tenderers in the tender at issue in the main proceedings to list their labour costs separately on the tender application form that they were obliged to use. Moreover, the specifications for that tender procedure stated that tenderers could not submit any document that had not been specifically requested by the contracting authority. |

| 30 | It is for the referring court, which alone has jurisdiction to rule on the facts of the main proceedings and the documents relating to the contract notice at issue, to verify whether it was in fact physically impossible for the tenderers to list the labour costs in accordance with Article 95(10) of the Code of Public Contracts, and to assess whether, as a result, those documents gave rise to confusion in the minds of tenderers, even though they expressly referred to the clear provisions of that code. |

| 31 | Should the referring court conclude that this was in fact the case, it would then be necessary to add that, in such a situation, having regard to the principles of legal certainty, transparency and proportionality, the contracting authority may give such a tenderer the opportunity to regularise its position and comply with the obligations under the relevant national legislation within a period set by the contracting authority (see, to that effect, judgment of 2 June 2016, Pizzo, C‐27/15, EU:C:2016:404, paragraph 51, and order of 10 November 2016, Spinosa Costruzioni Generali and Melfi, C‐162/16, not published, EU:C:2016:870, paragraph 32). |

| 32 | In the light of all the foregoing, the answer to the question referred for a preliminary ruling is that the principles of legal certainty, equal treatment and transparency, as referred to in Directive 2014/24, must be interpreted as meaning that they do not preclude national legislation, such as that at issue in the main proceedings, according to which failure to list the labour costs separately, in a financial tender submitted in a procedure for the award of public services, results in that tender being excluded without the possibility of supplementing or amending the tendering documentation, even where the obligation to list those costs separately was not set out in the tender documents, in so far as that requirement and that possibility of exclusion are clearly provided for by the national legislation on public procurement expressly referred to in those tender documents. However, if the provisions of the tender procedure do not enable the tenderers to list those costs in their financial tenders, the principles of transparency and proportionality must be interpreted as not precluding tenderers from being allowed to regularise their position and to comply with the obligations under the relevant national legislation within a period set by the contracting authority. |
