I think that Caleb is actually going to move to Brazil. Another LBP indicated to me that he too will be moving to Brazil within a few months. It seems that some people have circumstances (family, work, etc.) that make it easy to justify capitulation.
As for my case, the AGU filed the appeal about two months ago. I received a copy of it and wrote a detailed response to the judge's initial ruling and the AGU's appeal. I have not heard from anybody in the past few months. Aside from the case, I speak to my son every day (and my daughter maybe once a week) on the phone and am going to visit them next week. I will be in Brazil for three weeks (their winter vacation).
