The Supreme Court issued the Mims v. Arrow Financial Services decision today.  According to the syllabus, the Supreme Court held:

The TCPA’s permissive grant of jurisdiction to state courts does not deprive the U. S. district courts of federal-question jurisdiction over private TCPA suits. Pp. 7–18.  (a) Because federal law creates the right of action and provides the rules of decision, Mims’s TCPA claim, in §1331’s words, plainly “aris[es] under” the “laws . . . of the United States.” Arrow agrees that this action arises under federal law, but urges that Congress vested exclusive adjudicatory authority over private TCPA actions in state courts. In cases “arising under” federal law, there is a presumption of concurrent state-court jurisdiction, rebuttable if “Congress affirmatively ousts the state courts of jurisdiction over a particular federal claim.” Tafflin v. Levitt, 493 U. S. 455, 458–459. Arrow acknowledges the presumption, but maintains that §1331 creates no converse presumption in favor of federal-court jurisdiction. Instead, Arrow urges, the TCPA, a later, more specific statute, displaces §1331, an earlier, more general prescription.  Section 1331 is not swept away so easily. The principle that district courts possess federal-question jurisdiction under §1331 when federal law creates a private right of action and furnishes the substantive rules of decision endures unless Congress divests federal courts of their §1331 adjudicatory authority. See, e.g., Verizon Md. Inc. v. Public Serv. Comm’n of Md., 535 U. S. 635, 642. Accordingly, the District Court retains §1331 jurisdiction over Mims’s complaint unless the TCPA, expressly or by fair implication, excludes federal-court adjudication. See id., at 644. Pp. 7–10.
