The candidate's experience does not justify an abnormally low tender!
Rule n ° 1 :
When the public purchaser suspects an abnormally low offer, he is obliged to ask for explanations from the candidate. If there is no response or inaccurate response, the tenderer must be excluded from the consultation, pursuant to Article 55 of the Public Procurement Code.
Rule n ° 2 :
The candidate must provide clear and precise answers to the requests of the public purchaser. General explanations are insufficient. He must justify the proposed prices with regard to the object of the contract and his personal situation. The fact that companies have long experience and their status as previous market owners to justify their tariff proposal is not acceptable to the administrative judge. The Conseil d'Etat confirms its position already adopted in this sense (Conseil d'Etat, 29 October 2013, Département du Gard, application No. 371233) - the reasons given by the candidate's experience and the difficult economic situation are inadmissible ).
Rule n ° 3 :
In the event of rejection, the public purchaser must give reasons for his decision in order to allow the unsuccessful candidate to challenge the rejection before the pre-contractual judge. Failure to comply with these provisions constitutes a breach of transparency and competition requirements. The contracting authority may justify its decision a posteriori in the course of proceedings but imperatively before the judge rules.
