SCOTUS decision that reverses an Appeals Court judgment in MIMS v Arrow Financial Services to do with bringing private claims in federal court against telemarketers.

The Supreme Court decision opens the door for additional Telephone Consumer Protection Act (TCPA) claims against telemarketers - and apparently may permit federal class action litigation against TCPA violations (with potentially unlimited damages).

"The question presented is whether Congress’ provision for private actions to enforce the TCPA renders state courts the exclusive arbiters of such actions.
