The United Kingdom Court of Appeal has just rejected today’s appeals from the parents. (This little boy must die at the Alder Hey hospital.)
AFAIK the only way I know that this could be overruled would be for another EU state (i.e. Italy) to challenge this judgement in the Court of Justice of the European Union (Britain has signed up to the Maastricht Treaty on European Union) on a point of EU law : such as Britain failing to uphold the treaty in the matter of free movement between member states.
