Boys Refuses Chemotherapy

I read an article today about a young thirteen year old boy who is suffering from Hodgkin's Lymphoma. This young man and his family had decided that chemotherapy was not something they did not want. The boy, Daniel Hauser said that the treatment made him very sick and did not believe the chemotherapy would help him get better. The parents believe that chemotherapy is harmful to the body. They believe the alternative treatment he is following is getting him healthy and reducing the tumor in his body - which is vitamin supplements, ionized water, organic foods, and other dietary restrictions. His tumor has shrunk....
Well, a judge in Brown County and a team of oncologists where they reside - believe Daniel needs to be on Chemotherapy and yesterday the court ordered the parents to bring their son back to his chemo treatments.... In addition - the judge has ruled that Daniel is need of child protective services because they believe the mother may take her son and flee... she had done that previously to avoid the court discussion on the subject of chemotherapy.. The parents are seeking the court's forgiveness for fleeing and pleading with the court to let Daniel stay home surrounded by his family... the ruling is still pending..
The good new is that the most recent x-rays show a significant change in the tumor - what was once solid black is white and see through.. I will pray for this family..
My question is... when is it okay for a court to interfere in family's religious and/or alternative medicine choices... This I believe is a tough question... really tough... What do you think?
