The father brought a motion to change seeking a custody reversal and child support after the mother engaged in a concerted campaign of parental alienation.
Despite previous court orders for reunification therapy, the mother refused to comply.
The Office of the Children's Lawyer introduced expert and social worker evidence indicating the child's extreme views against the father had intensified, including threats of self-harm.
The court concluded that while the mother was responsible for the alienation, a custody reversal would likely fail and cause further harm to the child.
The child was ordered to remain in the mother's primary care with independent counselling, and the father's motion was dismissed.
