If the purpose of the lawsuit is really to use legal proceedings to force WT to change, they failed.
That's rubbish. The GB will not ADMIT the need for change, because they are deluded by their own beliefs. The fact that they haven't changed, only serves to expose their flawed policies for what they are, and opens the door to further lawsuits by those who may have been molested...say, during field service. The GB are shooting themselves in their collective feet.
It's no more of a failure than Neville Chamberlain's declaration of 'peace in our time' in response to Hitler's actions. Well, guess who eventually won the war?
