That was attempted actually during the course of the Justice Gomery inquiry. There were lawyers who wanted to take testimony before the public accounts committee and use it in those proceedings. We appeared before Mr. Justice Gomery. He was a bit surprised and ultimately ceded to the fact that it could not be allowed. The testimony given before the committee cannot be used in those proceedings. That was upheld later, when it was taken to court.
I don't know about the partisan witch hunt you referred to; I don't know what the connection is there. But the idea is that witnesses before this committee, or any other House committee, have the assurance that they can speak fully and frankly without concern that they're going to be somehow challenged in a legal proceeding elsewhere based on what they said.
I might further add that in my view it includes the police. They can't use testimony here as a basis to conduct an investigation. If they take testimony from here and find evidence that's helpful for some criminal prosecution purpose, they may be denied the opportunity to use that evidence because it's tainted; it has its genesis in an unlawful use of testimony.
