"At the argument, Justice Sotomayor sparred with Scott Stewart, Mississippi’s solicitor general, who was defending a state law banning most abortions after 15 weeks of pregnancy. “I’m not trying to argue that we should overturn those cases,” she said of the other decisions. “I just think you’re dissimilating when you say that any ruling here wouldn’t have an effect on those.” Mr. Stewart tried to distinguish the three other rulings from Roe, saying they were clearer, had given rise to more public reliance and did not “involve the purposeful termination of a human life.” Justice Sotomayor was unimpressed, saying all of the cases were grounded in the same kind of constitutional reasoning. “I’m not sure how your answer makes any sense,” she said."
