I'll come back to Mr. Barnes. I have a question on the same point.
Just to remind other colleagues, particularly those who aren't permanent members of the committee, we had requested a paper, Mr. Barnes, with respect to historical past practices. I find it fascinating that Tom is now raising it in his presentation. I wanted to get a sense of what status that might be at, because the point with that was to inform us about every time we had major changes to the Standing Orders. If you have that evidence or research, Tom, or if we could get a sense from the analyst, from Mr. Barnes, of the status with respect to that paper, it would be informative to us as a committee.
