The DA announcement is only "supposed" to happen when the subject "willingly and unrepentantly takes blood." Even then, the elders are to investigate the person's attitude to see if he or she is repentant. Also, they need to consider the circumstances such as extreme pressure being placed on the individual at that time. If the person shows repentance, or remorse, then the person would be removed of privileges, and possibly an announcement made in these words, "The elders have handled a matter having to do with Insert name here. You will be glad to know that spiritual shepherds are endeavoring to render assistance." If the person doesn't show repentance or remorse, then the DA announcement is made.
Although not written in the Flock book, when one recieves a transfusion unconsciously, its pretty much handled the same way. They're looking for repentance, or remorse, and also why the individual recieved a transfusion in the first place considering that the publisher should have had information on hand stating their beliefs on blood transfusions.
Oompa, I'm thinking in your situation, they were looking to axe you anyway. Your accident and the transfusion given later simply landed in their laps conveniently. Me personally, I say move on, but if you have a warrior's heart, then go ahead and make life difficult on them.
