On June 20, 2019, the Supreme Court released its long-awaited decision in PDR v. Carlton & Harris Chiropractic.

Instead of deciding that issue, however, the Court vacated the Fourth Circuit’s ruling and remanded the case for further development. How the Fourth Circuit rules on remand may ultimately provide more insight on how much deference is owed to the FCC’s TCPA interpretations.
