On Thursday afternoon, Mississippi attorney general Lynn Fitch filed a brief in the most important Supreme Court abortion case in three decades. 

In the brief defending the constitutionality of Mississippi's law prohibiting abortions after 15 weeks of gestation (with exceptions for when the life or physical health of the mother is endangered and in cases of severe fetal abnormalities that would prove fatal to the child), Attorney General Fitch argues that the Supreme Court's Roe and Casey decisions should be overturned and state legislatures should be allowed to pass laws protecting the lives of human beings in the womb.
