In a 5-4 decision announced Monday, the Supreme Court struck down a Louisiana law that severely restricted abortion in the state, marking a win for abortion rights advocates.
Chief Justice John Roberts, a crucial conservative swing vote, sided with liberal Justices Breyer, Ginsburg, Sotomayor and Kagan in issuing the majority opinion.
According to The Associated Press, Roberts has favored restrictions on abortion in two previous Supreme Court rulings.
