NARAL's press release calls the legislation's life of the mother exception "inadequate" and their background piece says the language for the life of the mother exception "confusing."
Is the following really "confusing?"
No licensed physician who performs a medical procedure designed or intended to prevent the death of a pregnant mother is guilty of violating section 2 of this Act. However, the physician shall make reasonable medical efforts under the circumstances to preserve both the life of the mother and the life of her unborn child in a manner consistent with conventional medical practice.
Seems pretty straightforward to me. A physician isn't guilty if he's trying to save the mother's life and also makes a reasonable effort to save the life of the child if it's possible.
