"Mary Ziegler, a Florida State University law professor and the author of “Abortion and the Law in America: Roe v. Wade to the Present,” said it was “impossible to overstate” the threat to Roe. She added that the court does not have to actually overturn the decision to void its impact, by eliminating fetal viability as the point at which bans are allowed. Without viability, it is not clear whether the court will impose any limit on abortion bans,” Ziegler said."
