For redaction, it's pretty straightforward, actually, in the act. Every now and then you'll see a document come out of two departments and it will be the same document slightly differently redacted, but the same criteria are being applied. It's human beings who are applying them. They make judgments, and sometimes they're different, but they aren't dramatically different. There is guidance in this, and one puts one's mind to asking, is this a true challenge to the national interest, to national security, for instance? Is this going to compromise an investigation under 16.1? Is this going to reveal advice to ministers?
Under section 21 it says you do not release advice to ministers. I think the release of the document of CIDA's president's advice to Minister Oda was wrong and shouldn't have been released. I know the Department of Justice thinks differently, but that was advice to a minister. I think what happens is there is a chill that comes out to public servants if they see their advice coming out in public. It is not desirable and it's better to keep it secret.
