It may depend on exactly what provisions we're talking about. If a minister has questions about how the cabinet system works, he may actually sit down and have a discussion with his deputy minister about that, or the clerk, but if we're talking specifically about the standards of conduct, one would expect that those are the questions that a minister would engage the Prime Minister or some of the Prime Minister's staff in.
