The Information Commissioner at the time recommended the banning of the pin-to-pin communication. What people need to understand is that employees of the public service need to respect their responsibilities under the act. Anything that they do should be, if it has a value for the work they do, saved somewhere on the government website.
The responsibility is on the employee to know, when they have these discussions with valuable information—where they provide the basis of decisions or basis of policies—that those should be in a memo, in a briefing note or in a document that is kept. If you have a bunch of emails back and forth, chats or pin to pin, those are actually very difficult to search. Sometimes, you'll end up with 50,000 exchanges just to find a little paragraph that talks about your decision-making power. This is where training and proper policy are needed.
