Looking at it realistically from their perspective, if they win the appeal, don't you think they would gleefully put out a press release and a comment in any media coverage about the case? One that says something like "By overturning this unjust decision, the court system has vindicated the reality that the sole person responsible for this sad case of abuse was a former associate of a congregation of Jehovah's Witnesses who has since been expelled. No court has ever found the Jehovah's Witness organization to be responsible for a case of child abuse. Jehovah's Witnesses abhor child abuse in all its forms and do everything they can to protect their children from this evil."
It seems like fighting for the chance to make statements like that one would be fairly attractive. They know dubs would read it and eat it up, seeing no reason to further investigate child abuse issues.
