Article 57 of that directive, entitled ‘Exclusion grounds’, provides in paragraphs 4 to 7 thereof: ‘ 4. Contracting authorities may exclude or may be required by Member States to exclude from participation in a procurement procedure any economic operator in any of the following situations: … (c) where the contracting authority can demonstrate by appropriate means that the economic operator is guilty of grave professional misconduct, which renders its integrity questionable; … (g) where the economic operator has shown significant or persistent deficiencies in the performance of a substantive requirement under a prior public contract, a prior contract with a contracting entity or a prior concession contract which led to early termination of that prior contract, damages or other comparable sanctions; (h) where the economic operator has been guilty of serious misrepresentation in supplying the information required for the verification of the absence of grounds for exclusion or the fulfilment of the selection criteria, has withheld such information or is not able to submit the supporting documents required pursuant to Article 59; … … 5. … At any time during the procedure, contracting authorities may exclude or may be required by Member States to exclude an economic operator where it turns out that the economic operator is, in view of acts committed or omitted either before or during the procedure, in one of the situations referred to in paragraph 4. 6. Any economic operator that is in one of the situations referred to in paragraphs 1 and 4 may provide evidence to the effect that measures taken by the economic operator are sufficient to demonstrate its reliability despite the existence of a relevant ground for exclusion. If such evidence is considered as sufficient, the economic operator concerned shall not be excluded from the procurement procedure. For this purpose, the economic operator shall prove that it has paid or undertaken to pay compensation in respect of any damage caused by the criminal offence or misconduct, clarified the facts and circumstances in a comprehensive manner by actively collaborating with the investigating authorities and taken concrete technical, organisational and personnel measures that are appropriate to prevent further criminal offences or misconduct. The measures taken by the economic operators shall be evaluated taking into account the gravity and particular circumstances of the criminal offence or misconduct. Where the measures are considered to be insufficient, the economic operator shall receive a statement of the reasons for that decision. An economic operator which has been excluded by final judgment from participating in procurement or concession award procedures shall not be entitled to make use of the possibility provided for under this paragraph during the period of exclusion resulting from that judgment in the Member States where the judgment is effective. 7. By law, regulation or administrative provision and having regard to Union law, Member States shall specify the implementing conditions for this Article. They shall, in particular, determine the maximum period of exclusion if no measures as specified in paragraph 6 are taken by the economic operator to demonstrate its reliability. Where the period of exclusion has not been set by final judgment, that period shall not exceed five years from the date of the conviction by final judgment in the cases referred to in paragraph 1 and three years from the date of the relevant event in the cases referred to in paragraph 4.’
