Don't get your hopes up that this signals some kind of sea change in the role of females in the organisation. I suspect that any modifications to the process will be only in cases of sexual assault and not some generic improvements that allow sisters to be involved in any case of fact finding.
I would suggest it would be something like:
- letter outlining some scriptural basis for a change that the GB have meditated on and decided to follow to keep JW processes regarding abuse way ahead of what everyone else is doing. Some kind of link to Deborah made. But a limitation made on "judging"
- announcement that anyone who wishes to report an allegation of sexual abuse can choose to talk to a couple of mature sisters
- either these are identified at a local level and publicly known within the congregation or the victim has to approach an elder and say they need to discuss a matter with the uber sisters and the elder assigns a couple of them to the victim
- sisters meet with victim and get victim's story
- report is made to the elders who then decide what to do
- sisters get reminded not to talk about anything to anybody but can't help wandering around with smug faces and making throwaway comments about "something going on but I couldn't possibly talk about it".
