If I’m reading this right, the court only decided if the hospital can decide to give a blood transfusion after the operation. But the kid is still free to decide if they’ll accept the operation in the first place (or you know, just never show up), the kid knows about the court case, so they know if they accept the operation they are accepting a potential transfusion. So whilst everything you say is true, it doesn’t change the original issue I pointed out.
