An application can not be rejected simply because of the absence of a certificate of professional qualification required by the consultation rules!
What you must remember :
The mere fact that a candidate does not possess a certificate of professional qualification required by the consultation rules is not sufficient to reject an application as incomplete or insufficient. The contracting authority must first verify whether the professional references produced in support of the application make it possible to demonstrate the candidate's ability to perform the contract correctly.
The rule of law:
Professional abilities make it possible to verify whether the candidate has the required qualifications, ie "proof of a certain level of professional competence". Proof of professional ability may be provided by any means, including references, professional justifications or certificates of professional qualification. As regards professional certificates, the contracting authority must specify that proof of the company's capacity can be provided by any means, in particular by professional identity certificates, attesting to the economic trader's competence to carry out the task. service for which he is applying.
