Here's my suggestion.
If you move it now that means we move to that item. The minister is here and has no obligation to participate in the discussion, which he's not going to do, and at 4:30 he leaves. We're losing our opportunity to talk about the estimates, which is what we brought him here for.
The option in my view would be for you to give us notice that in the second hour, in your turn—because we will start over again, you will get another turn—you move it then and that the committee deals with it then. If you want to ask questions of the minister of your motion that you intend to move in the second hour, then it will be part of your time. Otherwise we move on to debate on that particular motion.
I'm leaving it to you to decide what you prefer to do. He will not be responding because he's not a witness to this. That's committee business that you're moving. He's not on the committee.
