I know of no other situation in the past. I know of one situation when a commissioner asked for x and the panel said no, it's x minus y, and that was recommended to Treasury Board. But I don't know of a case in which an agent of Parliament went through the challenge function of Treasury Board Secretariat and a recommendation from the panel and what came out was different. I don't know of a case.
On June 3rd, 2009. See this statement in context.
