During his confirmation hearings, Chief Justice John Roberts indicated his preference for narrowly crafted decisions, dealing only with the case at hand.
That preference was demonstrated in both of today's 5-4 decisions. ObamaCare's contraceptive mandate was struck down, but only for businesses that are owned by a small number of people. Also, non-members of a single public employee union in Illinois won the right to refuse to pay dues to the union. Members of other unions gained no protection.
