Article I of the Nebraska Constitution shall be amended by adding a new section 31 that states as follows:

All persons shall have a fundamental right to abortion until fetal viability, or when needed to protect the life or health of the pregnant patient, without interference from the state or its political subdivisions. Fetal viability means the point in pregnancy when, in the professional judgment of the patient's treating health care practitioner, there is a significant likelihood of the fetus' sustained survival outside the uterus without the application of extraordinary medical measures.
