We don't have a constitution, you mean a change of legal precedent. I agree that's its and awful precedent to set. But it's already been done with Parliament declaring Rwanda safe, changing convictions doesn't seem so beyond the pale. I'm honestly not sure what else to do about it though. The sheer scale of incompetence and cover up in the post office and the software company will likely take years to sort through. Can the victims really wait that long? What is the alternative? Having everyone convicted file an appeal? After everything they've already gone through? Frankly, just wiping the slate clean and getting rid of all the convictions seem like the good move to me.
