Although the Court split 5-4, it did not split along usual left-right or formalist-pragmatist lines. Justice Kennedy wrote the majority opinion, joined by Justices Ginsburg, Breyer, Alito and Kagan. The Chief Justice dissents, joined by Justices Scalia and Thomas, and Justice Sotomayor dissents as well, albeit on quite different grounds. The Chief argues against restitution in this case, while Justice Sotomayor argues the majority’s opinion it too limiting.
