Yes, This is it exactly. A favorable court decision, does not guarantee a return order or preclude years of appeals and stalling a child's return. Most countries seem to be sit up this way. In Mexico they have the Amparo and numerous other avenues for endless delays. SageDad has had 8 trials and I believe 5 Amparos, or appeals filed. It takes a terrible toll on left behind parents and most seem to give up, due to financial or the emotional toll it takes on them.
Hopefully, Brazil may be headed toward a precedent sitting case. Perhaps this will be one.
It is wonderful to know that for Connor this wonderful judge did the right thing and he is reunited with his sons. I wish them a wonderful future and all the blessings they so deserve.
