Disclosures should be assessed and investigated discreetly, and in a way that maintains the confidentiality of the discloser and any subjects of a disclosure unless they have given consent for particular information to be disclosed.
The PID Act contains offence provisions that apply to the disclosure or use of information that does, or could, identify a disclosure.
When sending emails in relation to a potential PID, the subject line should make it clear that the email is for the addressee's eyes only.
