Oh, Judas Priest!
I can just about imagine the sisters who get to "assist" with a case, forever after acting high and mighty because they had a "privilege" not usually granted to sisters in the congregation. I'm sure that gossip would spread among the new class of helpers, their being able to talk "confidentially" to others who are now in this "assistant to the judicial committee investigation" class.
Quite certainly, the publications will spin this as a "loving arrangement", to have sisters help out, there being no Biblical restrictions on such a thing as women assisting a judicial committee. But just like with the compilation of the elders manual, I'm sure there will be all sorts of legalistic minutia and prohibitions that will rein in the new "mature JW female" assistants.
