Where does it say that the biological parents signed permanent custody to them. Can they show the paperwork? I doubt it.
Normally, don't you have to show abuse and refusal to change to lose parental right (at least in my State). Where is the evidence for that? Most Courts I know of prefer family reunification as soon as possible. Why was this not done in this case?
Um yes, the signed papers were presented in court. It was in the findings of facts in the middle beginning (it is a long read). It was also a finding of fact that the bio parents knew and understood what they were doing and that they did it voluntarily and without coercion. They sought the Bakers out and asked them to assume custody and that all subsequent behavior by them indicated that it was their intent and purpose to give up custody.
Until the INS came knocking to send them back to China. Then they file suit and the INS drops proceedings against them pending outcome. This happened not once, but twice. The second time the custodial family countersued to sever the parental rights to protect the child.
As for refusal to change - that was the judge's first point in his decision agains the bio parents.
