Here is the opinion in Ted W. v. State of Alaska. An excerpt:

This appeal arises from the superior court’s decision to allow a mother to revoke the Indian custodian status for her child’s father, whose own parental rights to the child had already been terminated. The father’s status as the child’s Indian custodian under the Indian Child Welfare Act was based solely on the mother’s temporary transfer of physical care and custody of the child to the father after termination of his parental rights. After the Office of Children’s Services (OCS) removed the child from the father and became the child’s temporary legal custodian, the mother joined in OCS’s motion to terminate the father’s status as the child’s Indian custodian. The superior court correctly reasoned that because the Indian custodianship was created solely by the mother’s temporary placement of the child with the father, that custodianship could be revoked by the mother who acted in concert with OCS as the child’s legal custodian. We therefore affirm the superior court’s decision.
