That's a good question. But I rather feel that we look at these "experts" as if they are infallible at times? Whatever side we may belong to. For when the defence employ experts they are quickly didmissed by the ccrc experts. So in the light of that I think we also have a right to challenge their views?
Yes I agree, and they are being challenged, the CCRC doesn't, or rather shouldn't simply dismiss things without reason, they should provide an explanation as to why something was dismissed, we just don't get to see the explanations that they give unless the defence choose to publish them.
I'm guessing at least in part, this is what the application for a Judicial Review is all about.
