Yes, I said that there's no clear dividing line between policy, operations, methodologies, and so on. What you don't want is to give the ministers the best of both worlds, what I would call “discretionary accountability”, where, when it pleases them, they can intervene and get their way through dinnertime directives, as I used to call them when I chaired the boards of crown corporations.
These instructions to the chief statistician at some point should come out in the open, but that's after a long process of back and forth. Then when the minister decides that he wants to overrule the chief statistician, or the government does—I think it should be a cabinet decision—then that becomes public, and the minister can boast and confess why he or she thought this was the right thing to do in the national interest. Presumably, there are skeptical, or if not, hostile, people in the opposition who will ask challenging questions for why this was the case.
I would even go so far as to say that the chief statistician should be allowed the opportunity to state publicly the reasons for his or her objections to a directive that related to operational matters.
