LONDÖN (AP) — A 12-year-old boy who has been in a coma for four months died Saturday at a London hospital after doctors ended life-sustaining treatment that was the subject of a lengthy court battle.

Archie Battersbee’s mother, Hollie Dance, said he died at 12:15 pm, about two hours after the hospital began withdrawing treatment. British courts had rejected the family’s request to transfer Archie to a hospice, and the European Court of Human Rights refused for a second time to intervene in the case.

“He fought until the very end,” Dance said, weeping outside the hospital. “I’m the proudest mum in the world.”

Archie’s care became the subject of weeks of legal arguments as his parents sought to force the hospital to continue life-sustaining treatments and doctors argued there was no chance of recovery and he should be allowed to die.

The family asked for permission to move Archie to a hospice after British courts ruled it was in his best interests to end treatment. The hospital said Archie’s condition was so unstable that moving him would hasten his death.

On Friday, High Court Judge Lucy Theis rejected the family’s request, saying Archie should remain in the hospital while treatment was withdrawn.

“I return to where I started, recognising the enormity of what lays ahead for Archie’s parents and the family. Their unconditional love and dedication to Archie is a golden thread that runs through this case,″ Thies wrote in her decision. “I hope now Archie can be afforded the opportunity for him to die in peaceful circumstances, with the family who meant so much to him as he clearly does to them.’′

The dispute is the latest UK case pitting the judgment of doctors against the wishes of families. Under British law, it is common for courts to intervene when parents and doctors disagree on a child’s medical treatment. In such cases, the best interests of the child take primacy over the parents’ right to decide what they believe is best for their offspring.
