I hadn't given much thought to whether it should go to one individual or a number of individuals, but I think it's the concern of Mr. Tilson that if there are frivolous complaints, there is no need to bog down an already bogged-down system with frivolous complaints.
I think it's also a quick way to determine if an individual has really committed a grievous action in that hearing. For instance, there was a judge at the Federal Court who was found to lack gender sensitivity, to put it lightly, and a complaint was filed by a number of crown lawyers in Calgary. It was deemed to be well founded by the Federal Court and the supervisors there. He was very quickly removed from hearing any gender-based claims.
It's the idea that justice has both to be done and seen to be done. I think that's the only effective way to do that.
