In this episode of Unwritten Law, NCLA’s Mark Chenoweth sits down with Senior Litigation Counsel Peggy Little to unpack the Supreme Court’s decision in McLaughlin Chiropractic Associates v. McKesson Corporation. Though the case began as a dispute over unwanted fax messages, the Court’s ruling has major implications for administrative law—particularly by striking down the restrictive "60-day rule" that previously blocked challenges to agency rules after an arbitrary, short deadline. Peggy explains why this decision restores meaningful judicial review, how it affects NCLA’s ongoing battles against administrative overstep, and why agencies can no longer avoid scrutiny simply by waiting out the clock.
