JP is the example you are referring to is the Lopez case where Losch did not attend the deposition. While yes Losch did defy the trial court's decision there is Due Process in the US and part of that is the fact that someone has the right to appeal to a higher level of court. If you don't think that it is right to appeal matters, that don't go in your favour, then I can't argue with you on your belief but it is the reality that is the way it is supposed to happen.
The 4th District Court of Appeals is also not the only court that has ruled that there is a distinction in the corporations and managing directors of those corporations used by Watchtower. There was also a Federal Court in the south that also ruled in that way. Watchtower provided the PMQ to answer questions so I am not sure what Mr Losch would have been able to offer, other than to attempt to humiliate him, which is a violation of California state law.
