The Supreme Court on Monday ruled in favor of deferring to administrative agencies in determining the scope of their own jurisdiction, issuing a 6-3 decision that featured a sharp dissent from Chief Justice John Roberts Jr.

The decision was one of four issued Monday—none of them the marquee cases the court is expected to rule on before the end of June. Late May is when the court clears the underbrush of somewhat easier and less hot-button cases in advance of the blockbusters that dominate June. The court has handed down 46 decisions so far this term, with 30 left to go. The court also granted review in five new cases to be decided next term, including a potentially major First Amendment Establishment Clause dispute.
