Unless otherwise provided in this Directive or in the national law to which the contracting authority is subject, in particular legislation concerning access to information, and without prejudice to the obligations relating to the advertising of awarded concession contracts and to the information to candidates and tenderers set out in Articles 32 and 40, the contracting authority or contracting entity shall not disclose information forwarded to it by economic operators which they have designated as confidential, including but not limited to, technical or trade secrets and the confidential aspects of tenders.

This Article shall not prevent public disclosure of non-confidential parts of concluded contracts, including any subsequent changes.

The contracting authority or contracting entity may impose on economic operators requirements aimed at protecting the confidential nature of information which it makes available throughout the concession award procedure.
