Let me refer you to the Speaker's ruling on the point of privilege by Mr. Jay Hill, who I believe was the whip at the time, on the last day of the last Parliament, in which he raised on a privilege precisely the point that you just made. The Speaker said, “I have received nothing from the committee. I can't make a ruling on it. But should a report come and I deem it to be beyond the mandate, it would not be receivable by the House.”
Your point is well taken, but those are the rules. The Speaker has no basis for making a ruling until he gets something formal from this committee.
