of the foetal membranes. " [1] On the same principle P. Antonelli thinks that it is lawful to remove an ulcerated womb which is threatening the life of a pregnant mother though the operation cause the death of the foetus, as also to remove an extrauterine foetus whose further growth would cause the certain death of the mother.

All who unlawfully procure abortion incur the penalty of excommunication, the absolution of which is reserved to the Bishop by Canon 2350.
7. Craniotomy, or any other similar operation which has for its immediate and direct effect the destruction of the life of the foetus, is a direct killing of the innocent, and is never allowed. If the child is already dead, there is of course no difficulty in permitting craniotomy or embryotomy, but if it is still alive it is not lawful to kill it, even if otherwise both child and mother were certain to die. Evil must not be done that good may come of it. The end does not justify the means. Some medical men consider the foetus, until it is born, as a portion of the mother which may be destroyed to save her life. This view is not in keeping with Christian principles, according to which the child has a soul of its own, and has its own independent right to live.
Some theologians used to think that such operations were lawful if the mother's life could not otherwise be saved, because the child might be considered a materially unjust assailant of its mother's life, and so be lawfully killed; or because when there is a conflict of rights the stronger right should prevail. However, in no sense can it be allowed that the child is an unjust assailant of its mother's life; it is where nature placed it, through no fault of its own, and it has a right to be there and to be born. If either is an unjust assailant of the other's life, it is the mother, who voluntarily undertook the obligations of motherhood. In the same way, when the stronger of two conflicting rights prevails, this is due to the fault of the other party, and such fault is out of the question in this case. This doctrine is now theologically certain after the repeated declarations of the Holy See that no operation which tends directly to the destruction of the life of the foetus is lawful.
When the child cannot be born in the natural way, and the life of both mother and child is in danger, Caesarian section or some similar operation may be, and should be, performed,
