"(4) Because Chevron’s justifying presumption is, as Members of the Court have often recognized, a fiction, the Court has spent the better part of four decades imposing one limitation on Chevron after another. Confronted with the byzantine set of preconditions and exceptions that has resulted, some courts have simply bypassed Chevron or failed to heed its various steps and nuances. The Court, for its part, has not deferred to an agency interpretation under Chevron since 2016. But because Chevron remains on the books, litigants must continue to wrestle with it, and lower courts—bound by even the Court’s crumbling precedents—understandably continue to apply it. At best, Chevron has been a distraction from the question that matters: Does the statute authorize the challenged agency action? And at worst, it has required courts to violate the APA by yielding to an agency the express responsibility, vested in “the reviewing court,” to “decide all relevant questions of law” and “interpret . . . statutory provisions.”" "Stare decisis, the doctrine governing judicial adherence to precedent, does not require the Court to persist in the Chevron project. The stare decisis considerations most relevant here—“the quality of [the precedent’s] reasoning, the workability of the rule it established, . . . and reliance on the decision,” Knick v. Township of Scott, 588 U. S. 180, 203 (quoting Janus v. State, County, and Municipal Employees, 585 U. S. 878, 917)—all weigh in favor of letting Chevron go. Chevron has proved to be fundamentally misguided. It reshaped judicial review of agency action without grappling with the APA, the statute that lays out how such review works. And its flaws were apparent from the start, prompting the Court to revise its foundations and continually limit its application."
