On this point of order, Mr. Chair, if I may, my understanding is that if an amendment or a subamendment would require the deletion of the entire thing it's trying to amend, the appropriate thing to do is proceed to a vote and then have a new amendment presented. I don't think an amendment can completely wipe out the entire content of a motion—in this case an amendment itself—that it's trying to amend.
