Perhaps I've missed something, but the case of Alfie Evans isn't the first of its kind and his parents had to take their case all the way through the supreme court to the European court of human rights.
Surely, once they have received as much medical advice as they can, the care of their children should ultimately be in their hands. For a court to decide to pull the plug on their life support, appears not only unjust, but barbaric.
Alfie died earlier today, even though the Vatican had offered treatment in Rome, but his parents were not allowed to take him there.
This is a legal summary of the whys and wherefores.
