Well, Mr. Chairman, I welcome that question, because it goes to the heart of what a parliamentary committee is about. Never mind legal proceedings or legal issues. You're a parliamentary committee: ask your questions, get your answers. The only thing you have to think about is not to comment on a case that's before the court; that's the court's business, and you shouldn't be commenting on that case.
What they say here stays here, in that sense. So the witness does not have to worry about what he is saying here, relative to some other proceedings somewhere else, because it doesn't go there. And the parliamentary committee members must be mindful of the fact that while they act responsibly throughout, and not be needless or reckless about what they say, it is still a proceeding of its own purpose, and its integrity rests with itself.
It's not the case that you have to be concerned about what may be said here impacting on legal rights or interests arising elsewhere.
