LONDON (AP) — Britain’s Supreme Court declined Friday to hear an appeal from a mother and father who want to take their terminally ill toddler to Italy for treatment instead of allowing a hospital to remove him from life support.

The decision is another setback for the parents of 23-month-old Alfie Evans, who have been engaged in a protracted legal fight with Alder Hey Children’s Hospital over their son’s care.

The Supreme Court decision means an earlier Court of Appeal ruling will stand. Justices in that court upheld a lower court’s conclusion that it would be pointless to fly the boy to Rome for treatment.

Alfie is in a “semi-vegetative state” as the result of a degenerative neurological condition that doctors have been unable to definitively identify. Earlier court rulings blocked further medical treatment and ordered the boy’s life support to be withdrawn.

In appealing the rulings, Alfie’s parents, Tom Evans, 21, and Kate James, 20, argued their son had shown improvement in recent weeks. But doctors said his condition was irreversible.

Pope Francis prayed Sunday for Alfie and others who are suffering from serious infirmities.

It was the second time the pope offered his views about a case involving a terminally ill British child. In July, Francis spoke out on behalf of Charlie Gard, who died a week before his first birthday from a rare genetic disease after his parents fought in court to obtain treatment for him outside of Britain.
