Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024), is a landmark decision of the Supreme Court of the United States in the field of administrative law, the law governing regulatory agencies. Together with its companion case, Relentless, Inc. v. Department of Commerce, it overruled the principle of Chevron deference established in Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. (1984), which had directed courts to defer to an agency's reasonable interpretation of an ambiguity in a law that the agency enforces.

In lieu of Chevron, the decision assigns the determination of congressional ambiguity to the judicial branch, with executive agency expertise still to be considered under the weaker Skidmore deference. Existing rules and case law already decided under Chevron deference were to remain in place from this decision. Both cases originated from fishing companies challenging a rule established by the National Marine Fisheries Service (NMFS) for fishing companies to pay for the cost of federal monitors that may be assigned to their boats, under authorization of the Magnuson–Stevens Fishery Conservation and Management Act (Magnuson–Stevens Act (MSA)). The company claimed that the Act did not allow NMFS to pass the monitors' costs to the fishing companies, challenging Chevron deference that was applied in favor of the NMFS during lower court hearings.Loper Bright Enterprises, Inc v. Gina Raimondo, 45 F.4th 359, 365 (D.C. Cir. 2022) (found online at https://law.justia.com/cases/federal/appellate-courts/cadc/21-5166/21-5166-2022-08-12.html, p. 6)

Background In 1976, Congress passed the Magnuson–Stevens Fishery Conservation and Management Act, which was intended to provide for the management of marine fisheries in United States waters.16 U.S.C. 1801(b)(1) (found online at https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title16-section1801&num=0&edition=prelim) One of the Act's provisions authorizes the National Marine Fisheries Service (a subsidiary agency of the United States Department of Commerce) to require fishing vessels to "carry" federal monitors on board to enforce the agency's regulations, particularly to prevent overfishing.

The New England Fisheries Management Council (NEFMC) is a council that regulates fisheries in federal waters under the Magnuson-Stevens Fishery Conservation and Management Act. NEFMC develops fishery management plans for fisheries off the coasts of Maine, New Hampshire, Massachusetts, Rhode Island, and Connecticut. One such fishery is the Atlantic herring fishery. Unlike in North Pacific and foreign fisheries, the Magnuson–Stevens Act (MSA) does not explicitly require Atlantic herring fisheries to pay the costs of federal monitors. In addition, budgets for NMFS had been falling in recent years. As a result, NMFS had been unable to pay for increased monitor coverage in the Atlantic herring fishery.

Starting in 2013, the NEFMC started to implement a workaround to this issue. It began to develop an amendment to the New England fishery management plans that would give the council the power – though not explicitly given in the MSA – to require the fishing industry to pay the costs of additional monitoring. The NEFMC submitted this amendment to the NMFS, which in February 2020 published its final rule establishing a standardized process that would require industry-funded monitoring across New England fisheries.

Prior precedent The Supreme Court ruled in Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., , that courts must defer to the authority of an administrative agency's interpretation of a statute whenever both the intent of Congress was ambiguous and the agency's interpretation is reasonable or permissible. In its opinion, the Court outlined a two-step test on when to grant deference, known as Chevron deference. The Court reasoned that ambiguities in statute may be a delegation of authority from Congress, thus limiting a federal court's ability to review an agency's interpretation of the law. In the specific case at the heart of Chevron, the challenge arose from the United States Environmental Protection Agency's interpretation of what defined a source of production of pollution in its authority granted by Congress through the Clean Air Act.

In the first step of the test, the Court would ask whether there was an unambiguous expression of Congressional intent contained within the statute. If so, then the Court must yield to Congressional intent. If not, then the Court would proceed with the second step of the test. It would ask whether the agency's application of the statute was based on a "reasonable" interpretation of ambiguous wording. If so, then the Court would defer to the agency's interpretation of the statute. If not, then the agency's interpretation would likely be deemed impermissible. Here, reasonability was determined by the specific factual circumstances present in the case.

Since being handed down, Chevron had become among the most frequently cited cases in American administrative law. Over 17,000 lower federal court decisions and 70 decisions by the Supreme Court itself cited Chevron. Between 2003 and 2013, circuit courts applied Chevron in 77% of decisions regarding regulatory disputes.

In years prior to the current case, the Supreme Court, with a majority of conservative justices, had been seen as leading towards weakening or overturning Chevron. In West Virginia v. EPA, , the Supreme Court ruled against parts of an emissions-related rule created by the United States Environmental Protection Agency, asserting that the agency did not consider the costs of implementation of their rule. While this case did not overturn Chevron, it defined the major questions doctrine that was used in future cases to question the interpretation of administrative law when the financial impact of the law had not been considered by the agency, such as in Biden v. Nebraska, , which blocked President Joe Biden's student loan forgiveness project under the HEROES Act for failing to account for its financial cost to states.

Lower courts Loper Bright Enterprises is a New Jersey–based family-owned herring fishing company operating in the waters of New England; the company estimated the cost of federal monitoring to be about $700 per day. In February 2020, Loper Bright filed a lawsuit in the United States District Court for the District of Columbia alleging that the MSA did not authorize the NMFS to mandate industry-funded monitoring of herring fisheries. The District Court, applying Chevron, granted summary judgment in favor of NMFS. Despite Chevron providing deference in the case of an ambiguously worded statute, the District Court found that the MSA unambiguously provides for industry-funded monitoring of the herring fishery, and thus concluded its analysis at the first step of Chevron. The Court acknowledged Loper Bright's arguments regarding ambiguity in the statutory language, but noted that even if these arguments successfully argued for ambiguity in the text, NMFS's interpretation of the MSA would have been a reasonable reading of the statute.

A three-judge panel of the United States Court of Appeals for the District of Columbia Circuit heard oral arguments in the case on February 8, 2022. The panel included then-Circuit Judge Ketanji Brown Jackson. Later that month, Jackson was nominated to replace Justice Stephen Breyer on the Supreme Court. Chief Judge Srinivasan was drawn to replace Justice Jackson after her confirmation. Despite hearing oral arguments, Justice Jackson took no part in the decision of the case.

The court affirmed the judgment of the district court. However, the Circuit Court did not rest its analysis at the first step of Chevron, concluding that the language of the MSA was not completely unambiguous about whether or not it provides for industry-funded monitoring of the herring fishery. Instead, they concluded their analysis at the second step of Chevron, stating that the NMFS reasonably interpreted the MSA when it came to what the Court deemed the "silence on the issue of cost of at-sea monitoring". Judge Justin R. Walker dissented.

Supreme Court

On November 10, 2022, Loper Bright petitioned the Supreme Court to hear its case. In its petition for a writ of certiorari, Loper Bright presented two questions to the Court. First, it asked the Court to rule on whether granting the NMFS the power to require domestic vessels to pay the salaries of monitors it carries was based on a proper application of Chevron. Second, it asked the Court to rule on whether Chevron should be overruled outright, or at least limited in its scope. On May 1, 2023, the Court granted the petition, limited to the second question presented. Due to her prior involvement in the case, Justice Jackson recused herself from its proceedings. The Supreme Court later granted the petition to Relentless, Inc. v. Department of Commerce in October 2023, a closely related case originating out of the First Circuit also challenging the fees issued by the NMFS and Chevron deference, with which Justice Jackson had no conflict.

Loper Bright was heard alongside Relentless, Inc. on January 17, 2024. The cases were argued by Roman Martinez (on behalf of Relentless), Paul Clement (on behalf of Loper Bright Enterprises), and Solicitor General Elizabeth Prelogar (on behalf of the United States in both cases). Although Justice Jackson recused herself in the Loper Bright decision, she did hear arguments in the consolidated case, Relentless, Inc. The oral arguments and questions from the justices were centered largely around the role of the courts in policy interpretation, and what might happen to the courts should Chevron be overruled. Additionally, attention was given to the impact which overruling that precedent would have on certain industries, with healthcare being center-stage.

On June 28, 2024, the Supreme Court issued its decision striking down Chevron deference. Loper Bright was 6–2 with Justice Jackson excused and Relentless was 6–3. Chief Justice John Roberts wrote the majority opinion, which held that Chevron deference conflicted with the Administrative Procedure Act (APA) as "under the APA, it thus remains the responsibility of the court to decide whether the law means what the agency says." Justice Roberts continued that "Congress expects courts to handle technical statutory questions", and the judicial venues allows for additional input from interested parties via amicus briefs. Justice Roberts' opinion stated that prior administrative actions and court decisions decided under Chevron deference are not overturned by this decision, and in lieu of Chevron, agency interpretation can still be respected under the weaker Skidmore deference established in Skidmore v. Swift & Co. (1944). However, Justice Roberts said, the principle of stare decisis does not apply to Chevron deference in general as the court had been struggling to apply it over the last several years, making it unworkable. In the specifics of the Loper Bright case, the majority opinion also found that the 1976 Magnuson–Stevens Fishery Conservation and Management Act did not authorize officials to create industry-funded monitoring requirements.

Justice Thomas wrote a concurrence, stating that Chevron deference was inconsistent with both the APA as well as the separation of powers established in the Constitution. Justice Gorsuch also wrote a concurrence, stating "Today, the Court places a tombstone on Chevron no one can miss. In doing so, the Court returns judges to interpretative rules that have guided federal courts since the Nation’s founding." Justice Gorsuch further wrote that the only change in administrative law going forward is that federal courts should "resolve cases and controversies without any systemic bias in the government's favor."
