What I'm suggesting is.... If you recall, one doesn't have to think too hard about the expert witnesses who gave rise to people pleading guilty to offences they never committed. There were a lot of them. That happens very often. A court of appeal would never touch those cases. They would simply go to prison without appeal. Those are the cases that we think about. I think there would be a lot of those cases.
In fact, I think the vast majority of cases would be that way. Consequently, if you're relying on a court of appeal to give a decision on it, you're going to miss out on the vast majority of cases that are entitled to it.
