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.
i don't know what country you're from, but it's most certainly NOT the law in the united states.
