I'm glad we're having this discussion because I too am learning something new. My understanding of this, the way it has been put forward, is that for any three of the vice-chairs—assuming a third one was created—if Mr. Richards also happened to be the deputy whip of his party, he would have to forgo one of the salaries. It doesn't need to indicate which one, which I think might be problematic. Does he get to pick or how is which one he forgoes chosen?
I thought that the intent of this originally was that if you are the vice-chair of this committee and you're the vice-chair of another committee, then you shouldn't be double-dipping. You can only take the salary from one of them. It doesn't apply to any other duties or responsibilities that have been assigned to you.
Along with what Mr. Turnbull is saying, I would agree that I see the potential problem in playing two vice-chair roles in taking the salary twice, but I don't see the problem if Mr. Richards was also the deputy whip of his party. The demands that would bring would be completely separate from the demands a committee would bring.
