Can a candidate for a public contract, on his own or at the invitation of the contracting authority, rectify a purely material error that taints his BPU?
Rule n ° 1:
In the context of a formalized procedure, the Council of State has already had occasion to recall that it is not possible to regularize an irregular offer, that is to say which does not comply with the requirements of the specifications (EC 4 March 2011, Reunion Region, application No. 344197).
Rule n ° 2:
In the context of a tendering procedure, the contracting authority may not negotiate with the candidates in the name of the principle of inviolability of tenders. The Council of State recalls that if this principle precludes any modification of the amount of the offer on the initiative of the candidate or the contracting authority, it can not be applied in the exceptional case where it is a question of rectifying a purely material error of such a nature that no one could rely on it in good faith in the event that the candidate sees his successful offer. Such is the case of a candidate who indicates to the contracting authority that he has made an error on one of the BPU prices which was 220 euros instead of 22 euros.
Rule n ° 3:
From the moment the initial tender submitted by the tenderer complies with the specifications, a contracting authority may not subsequently declare it irregular on the basis of the additional information provided by the exhibitor to the tenderer. further clarification that he asked him to provide if these clarifications do not change the content of the offer (TA Versailles, October 10, 2011, Sté SARL BAILLY Enterprises, No. 1105385).
