Confidentiality is a fundamental principle in mediation. The parties, attorneys, the mediator and other persons who take part in the process are subject to a duty of confidentiality regarding information and documents obtained in the process, unless otherwise agreed. A mediation invitation, a proposed solution, a declaration of acceptance, or documents and statements prepared solely for the process cannot, within the limits in the law, be used as evidence in a later action or arbitration, and no testimony may be given about them.
However, if a contract, invoice, e-mail, delivery record, technical report or other evidence also exists outside mediation, the mere fact that it was presented at the meeting does not by itself make that evidence unusable. Confidentiality also does not give a right to conceal acts constituting a crime, to remove mandatory reporting obligations or to process personal data without limit.
In corporate and international files, the confidentiality agreement, data processing roles, access authorizations, virtual data room, and the obligations of interpreters and technical experts should be regulated separately.
Confidentiality and the prohibition on evidence do not have the same scope. The statutory prohibition on statements and documents in Law No. 6325 Art. 5 should not be reduced to a general confidentiality agreement alone. Disclosures required by law and cases necessary for implementing the agreement are assessed separately.
Legal basis: Law No. 6325 Arts. 4–5; the relevant data protection provisions.
