Thank you very much, Madam Chair.
Mr. Julian, you're referring to a case that occurred in 1993. When Ms. Champagne was Deputy Speaker of the House, she was also asked to chair a Progressive Conservative convention at which Ms. Campbell was elected party leader.
A question of privilege was then raised in the House regarding Ms. Champagne's participation in that partisan activity. The Speaker of the House at the time, Mr. Fraser, responded that expectations of impartiality and duties might not be as high for Deputy Speakers as for Speakers, as Deputy Speakers could at times attend their party's caucus meetings. In those circumstances, it therefore wasn't considered a question of privilege.
It seems to me he also noted the fact that the conduct of occupants of the chair is not normally criticized through a question of privilege but rather by means of a substantive motion.
