I think Don's comments are absolutely correct. The Speaker can make a decision on this matter if it's raised there, but whether it would be raised is another issue. Matters do come that way, occasionally, before the Chair. The Chair can decide whether Parliament's privileges have been breached by this kind of action. I think it probably would have been decided that way—that's my guess, anyway.
