Their own findings contradict your assessment. They didn’t side with the dad. They sided against the Christian influence on the daughter. Read what is written. Socially and academically well adjusted, in public school classes and extra curricular activities.
But needs to be in the public school MORE to counter the religious influence of the mother and challenge her beliefs.
That is not a ruling in favor of dad, it is a ruling against mom and homeschooling.
Does this mean the father has a say as well, or is it only the mother.
