However - round our way when this sort of thing rarely arose the elder on the body with lots of opinions and usually with his family all in will make waves about successful faders and waffle on about what the GB really want us to do even if it's not in print. (roll eyes).
If there are enough of them they will lean on the party giver or the party giver will be so conditioned that they will ask the advice of the elders either before or after inviting a fader.
When there is a "conscience decision" to be made - they (most JW elders) are a bunch of tight-knickered assholes looking to maintain control to look good in the eyes of the CO or Branch. Nothing to see here ...
