My guess is that there might be new rules stipulating that judicial matters come under the direct purview of the CO and not the branch or headquarters (like they did with the appointment of elders and ministerial servants). So all records of a judicial nature will be sent to the CO and not the branch or headquarters. Of course what the CO decides to do with those records is his prerogative, without nothing in writing stating the CO has to pass those records on to the branch or headquarters, Watchtower cannot be held liable because some CO decides to share information with them on his "own initiative", can they?
So maybe the elders might receive a new shepherd the flock book eliminating all the references to judicial committees and the secret record-keeping that surrounds them. Then when the CO comes and he has his special meeting with the elders he'll just give them his own "suggestions" on how to handle judicial matters, which the elders would have to record in their own hand in their own notebooks. Of course, there will be striking similarities between the CO's "new" rules for judicial matters and the old rules that were given by the organization in the shepherd book. The major difference here will be that any legal ramiffications resulting from the judicial process will now fall squarely on the back of the CO and not Watchtower.
