Professor David Farrell:

The general rule of thumb is that one needs a decent critical mass. One of the leading people in this area, Kaare Strom, said about ten or 11 would be the ideal number. Obviously, it depends on the number of parliamentarians one has to play with. We have a small Parliament, so there are only so many Members available. That is why I was trying to suggest that one way to help move towards this ideal world that I tried to outline would be to move to a situation where a Member sat on only one committee.
