It depends -- it would have to depend on what circumstances. I think that I've said earlier, in another forum, that the idea of having an audit trail on every single story that is published is probably not practical. However, if there is a story where there is a clear debate over public interest, then any standards panel should be able to say, "What were the exchanges here?" and: "We're going to need to see that documentation."
So as I said, it would depend on the individual case, but as a general rule, "Right, we want anything and everything", no.
