Thanks, too, jno. I suppose what I was getting at was that this seemed to be a pretty pointless exercise. It was obvious (or at least it felt obvious, to me and presumably most others on AB) that the Colston Four were, in at least a literal sense, guilty of breaking the law already. But the Jury was entitled to acquit, and presumably remains entitled to acquit, in spite of this clarification. I suppose the removal of a particular line of defence, or at least the tightening of it, makes some difference, but really the point is that this is what happens with Jury trials. You take a group of common citizens, sit them in a room, ask them to reach a verdict without explanation, and accept that, at times, they'll decide that sure, this person broke The Law, but The Law is an ass, so "Not Guilty".
It's an important protection.
