I thank the hon. member for submitting that point of order.
As advised, I agree that the subamendment is beyond the scope. I will quote the section in Bosc and Gagnon that refers to it. It states:
Most of what applies to amendments applies equally to subamendments. Each subamendment must be strictly relevant to, and not at variance with the sense of, the corresponding amendment and must seek to modify the amendment and not the original question.
