They simply need to:
(1) disband the HLC so they are not "guilty" of pressuring anyone to refuse treatment;
(2) relay to BOEs verbally via COs that due to Satan early hordes using the BT to attempt to destroy the Org, BT will NOT result in DF anytime a person "repents" (this is more or less the unwritten rule currently);
(3) gradually move it to a contentious decision that everyone must deal with personally between himself & Jehovah. When a question regarding a BT arises, it can be dealt with on an individual basis through the Service Dept (who will decide all cases should be ignored).
