Andrea Levy's Mother Jones article argues that fetal viability, the common compromise line in abortion law, is far more ambiguous than it appears, tracing the term from 1820s English courts through Roe v. Wade to its role in today's post-Roe battles. It centers on Kate Dineen, who was denied an abortion in Massachusetts after her son's catastrophic in-utero stroke, terminated in Maryland, and helped push the state to eliminate its viability line in 2025.
