It probably exists today. But to go back a step, when somebody submits a request to an institution, and in it there is his or her personal information--his name, his address, his date of birth--it's provided for a specific purpose: to obtain access to information in records. If you're going to use this personal information for any purpose other than satisfying the request, then you can do it in one of two ways. You can either ask consent of the individual, saying, “Do you give me consent to divulge or to disclose?”, or whatever, or do it on an issue of public interest. The Privacy Act says you can disclose personal information on an issue of public interest.
If it is not one of those two issues, then you're in violation of the Privacy Act. If you're going to say you will now use this information to let your communication staff or anybody else--deputy ministers or political staff--say, “By the way, John Smith has asked this request because of...whatever”, that is not required to process a request and to disclose records, and that would be in violation of it.
