you're right, IF there are complications that would kill or cause serious permanent injury to the mother. otherwise, you're wrong.
There are no such legal restrictions.
It goes to the legal definition of 'birth'. If any part of the baby remains in the canal, it's not a legal live birth. Abortion procedures must be performed prior to birth, by definition.
I'm not going to argue with you anymore. That's the law. If you don't want to believe it, that's not my problem.
