The change to the appeal committee is relevant but in practice the appeals that I seen turned over were in fact the case of the subject expressing their repentance better and in a different way at the appeal.
This may be what is changing. Remember, the Appeal Committee is hand-picked by the CO. They are not just local elders chosen at random. These Company Men will be there to protect the Borg. They will be entrusted to determine if the person being DF could pose a risk to the Borg if they are DF. Does the case open up any kind of liability to the Borg? Does it in any way make it possible to bring a charge of them violating Human Rights?
They won't be there to determine repentance. They will be there to determine risk!
