Yes, but I can speak to that as well.
It's called redundancy. In other words, the purpose of the two amendments is very similar, if not identical, but the wording is different.
PV‑6 is in order, but if it were adopted in addition to the BQ‑5 we adopted a moment ago, it would create redundancy, which would lead the legislative clerks and department lawyers to have to arbitrate the will of the committee. Since the committee would have adopted two very similar amendments, it would be up to the experts in the department and the House of Commons to arbitrate for the committee, since these two amendments would be redundant.
