Mississippi Governor Phil Bryant yesterday signed into law HB 1510, the Gestational Age Act (full text) (bill status history). It prohibits abortions after 15 weeks of gestation except in the case of medical emergency or severe fetal abnormality. There are no exceptions for rape or incest. Violations of the ban are defined as unprofessional conduct by a physician and may lead to suspension or revocation of the person's license to practice medicine. New York Times reports that the only abortion clinic in Mississippi quickly filed a complaint (full text) (press release) in Mississippi federal district court challenging the constitutionality of the law.
UPDATE: On March 20, a Mississippi federal district court granted a temporary restraining order against enforcement of the new law. (AP)
