6. A public office holder is bound to discretion in regard to anything that comes to his knowledge in the performance or during the performance of his duties and is at all times bound to maintain the confidentiality of information thus received.
That obligation does not have the effect of preventing a public office holder from reporting to a specific interest group that he represents or to which he is linked, except where the information is confidential by law or where the board of directors requires that confidentiality be maintained.
