In this episode, we unpack the Supreme Court’s unanimous decision in Cunningham v. Cornell University — a landmark ERISA case with major implications for retirement and health plan fiduciaries. We explain the facts behind the case, what “prohibited transactions” really mean, and why the Court's ruling on affirmative defenses matters. If your health plan pays fees to TPAs, PBMs, IDR vendors, or brokers, this episode is for you.
