That's a matter for the investigators, not for me. There are two issues particularly that have been mentioned. One is cross-examination of witnesses—that's not appropriate for an inquisitorial process. That happens in a trial—as a lawyer, I know that.

Second is the suggestion that witnesses should be compellable. Again, there's no legal basis for doing that in a non-statutory inquiry. So, there is a restriction on what can be done in terms of the law.
