Amendment One says this:
Shall Article I, of the Constitution of Tennessee be amended by adding the following language as a new, appropriately designated section:
Nothing in this Constitution secures or protects a right to abortion or requires the funding of an abortion. The people retain the right through their elected state representatives and state senators to enact, amend, or repeal statutes regarding abortion, including, but not limited to, circumstances of pregnancy resulting from rape or incest or when necessary to save the life of the mother.
