I think those are all fair points. Even if your desire is perhaps not to be partisan, sometimes having a minister in front of you is just a temptation that's too hard to resist. Maybe I can suggest that we do invite the department, as David mentioned, to send a written brief, if they wish. Then there's no worry about that leading to any kind of back-and-forth. It's part of the testimony as a written brief submitted. This happens with our studies, of course. Written briefs are submitted. As I understand it, they are as much a part of the evidence as anything else. There's just not the back-and-forth questioning piece of it.
So let's be intentional about inviting that input, if it's desired. I think that will help strengthen our study while leaving the hearings themselves for the outside witnesses.
