I think I spoke to this issue. I hope that it wasn't during the whips' meeting, where the majority of people were not in attendance, including the clerk. The wording of Standing Order 115(5), which is going to be rewritten, refers to the first division bells sending members to a vote. However, a quorum call is not a vote. Not all committees will suspend. As I understand it, it's only when there is a vote.
As long as the magic number... It will be up to other members and the whips to round up other members not sitting on the committee. I understand that committees will not stop their deliberations when there is a quorum call. We are talking about votes.
