Old hippie,
I guess I'm one old hippie too.
Yes you can appeal and win some times, BUT and here is the big buts:
But if you are DF for apostacy, I don't think you stand a chance.
Hypothetical case in point:
Superior Authorities in Romans 13.
Say it is before 1960 and you go around the congregation and start telling every one that absolutely no-way can the superior authorities be Jesus and Jehovah, but according to the context are the governments.
So the elders form a judicial committee to DF you for apostacy. At this meeting you want to show why you are right, but they have to stick strickly to the WT explanation at the time.
Will they let you use reason and common sense logic to prove your point? No.
If after you get DF'd and appeal to the Society will they listen to your defense if it disagrees with their Official teaching on the subject, and reverse the elders desision to DF? NO!
And lets say 2 years latter 1962(I think) they change back to Superior Authorities are now the Governments.
Will they now reinstate you because you were right after all? NO.
They will let you stay DF'd even if they were wrong to DF you, and you were right in your interpetation.
Is that justice?
If someone lived a trillion X longer than you, and had a billion X more reasoning ability would he come to the same conclusions as you?
