22   Confidentiality guideline

(1)  An investigating authority or public authority (or officer of an investigating authority or public authority) or public official to whom a protected disclosure is made or referred is not to disclose information that might identify or tend to identify a person who has made the protected disclosure unless:

(a)  the person consents in writing to the disclosure of that information, or it is generally known that the person has made the protected disclosure as a result of the person having voluntarily identified themselves (otherwise than by making the protected disclosure) as the person who made the protected disclosure, or

(b)  it is essential, having regard to the principles of natural justice, that the identifying information be disclosed to a person whom the information provided by the disclosure may concern, or

(c)  the investigating authority, public authority, officer or public official is of the opinion that disclosure of the identifying information is necessary to investigate the matter effectively or it is otherwise in the public interest to do so.

(2)  As part of its procedures for receiving, assessing and dealing with protected disclosures, a public authority must establish procedures for ensuring that a public official who belongs to the public authority maintains confidentiality in connection with a protected disclosure made by the public official.

Note. These procedures are required to be the subject of a policy of the public authority under section 6D.
