It would be totally inappropriate in the middle of a bell summoning members to vote in the chamber for the chair to be replaced with 17 minutes left. I think that's inappropriate, and I would move that it's not a situation wherein a vice-chair should convene a meeting in the absence of a chair who was here in the first place.
I don't know what you're up to, Andrew, but there's 16 minutes before a vote is required and we need to be in the House, and all members should be marshalling towards the House during a bell. I would say it's totally inappropriate for you to assume jurisdiction of any kind, as vice-chair, under those circumstances.
