(2)The Hamburg Commissioner for Data Protection and Freedom of Information shall be obliged, including after termination of the official relationship, to maintain secrecy regarding matters that have come to his or her knowledge in an official capacity. This shall not apply to communications in official dealings or to facts that are publicly known or that by their nature do not require confidentiality.
