But “after-birth abortion” is a term invented by two philosophers, Alberto Giubilini and Francesca Minerva. In the Journal of Medical Ethics, they propose:

[W]hen circumstances occur after birth such that they would have justified abortion, what we call after-birth abortion should be permissible. … [W]e propose to call this practice ‘after-birth abortion’, rather than ‘infanticide,’ to emphasize that the moral status of the individual killed is comparable with that of a fetus … rather than to that of a child. Therefore, we claim that killing a newborn could be ethically permissible in all the circumstances where abortion would be. Such circumstances include cases where the newborn has the potential to have an (at least) acceptable life, but the well-being of the family is at risk.

Saletan explores how the pro-infanticide position derives logically from pro-choice premises, then says:

The challenge posed to Furedi and other pro-choice absolutists by “after-birth abortion” is this: How do they answer the argument, advanced by Giubilini and Minerva, that any maternal interest, such as the burden of raising a gravely defective newborn, trumps the value of that freshly delivered nonperson? What value does the newborn have? At what point did it acquire that value? And why should the law step in to protect that value against the judgment of a woman and her doctor?
