The Court's Opinion is
here. The majority (Roberts, Ginsburg, Breyer, Sotomayor and Kagan) wrote a very narrow opinion-- a law saying that no one but clinic staffers and patients can be within 35 feet of the clinic is too broad, because a narrower law could protect the clinics from disruption by protestors. The other four Justices (Kennedy, Scalia, Thomas, Alito) concurred in striking down the law, but would have decided it on much broader grounds-- they say any law that protects only abortion clinics but not other kinds of buildings is always unconstitutional.
