Seems to me that future lawsuits must be directed both at the Watchtower [Corporation] AND at the Governing Body as well, since they clearly attempt to legally disentangle themselves, whilst 'spiritual oversight entity' over the Jehovah's Witnesses, from the Administrative, corporate entity. Therefore, who decides the doctrinally-driven policies isn't the Watchtower per se, but solely the Governing Body.
At least until some jurisprudence establishes a chain of command between the Governing Body and the Watchtower. We all know it exists, but prove it in a court of law is a whole other ball game. Remember, both entities were legally separated in 2000 under Henschel.
