Imposed separation of conjoined twins— moral hubris by the English courts?

Late last year the English Court of Appeal confirmed a lower court's ruling that doctors could impose an operation to separate recently born conjoined twins, overriding the refusal of consent of their parents. The fact is that there are-as is characteristic of all moral dilemmas-strong moral reasons for coming to two moral conclusions that are mutually inconsistent, at least in the sense that both cannot be achieved and sometimes in the sense, as here, that they are mutually contradictory. [...]there are strong moral reasons for not killing one baby to save the other even at the cost of the tragedy that both will die; and there are strong moral reasons for saving one baby's life rather than allowing both to die, even at the cost of the tragedy that one will be deliberately killed.
