This is slightly off topic, but just to illustrate that the H.Spirit has NOTHING to do with JC decisions, a number of young B&S's had a party, a number stayed over, a Bro and Sis shared a bedroom for the night, only one bro. knew this for sure,(layout of the house, attic rooms) others guessed.
He, the one who knew for sure, was called before a JC and asked if they had shared a room, he lied and said "No", so the young couple got off. The "Bro" that gave false witness no longer believes any of the WT BS but attends to protect his mother from his abusive Elder father, the Elders are not aware that he no longer believes.
Holy Spirit ? It isn't in any JC proceedings.
OODad , why the question ? from the above, it has happened but rarely, so good luck.
