Americans for Prosperity Foundation Applauds Trump EPA’s Decision to Repeal Endangerment Finding and Restore Democratic Accountability

Feb 17, 2026

Americans for Prosperity Foundation applauds the Trump EPA’s decision to repeal the agency’s 2009 Endangerment Finding—a document the agency has used as a springboard to claim sweeping power under the Clean Air Act to unilaterally set national transportation and energy policy by administrative edict without Congress’s permission. The Endangerment Finding has underpinned a host of burdensome and expensive EPA regulations impacting the entire national economy and the daily lives of Americans, including the price we pay for basic consumer goods. By repealing it, President Trump, Administrator Zeldin, and EPA have taken yet another bold step to unleash prosperity, restore American energy dominance, and lower costs. As the Washington Post Editorial Board said, supporting the decision, “It’s about time.” This historic deregulatory action will make buying a new car more affordable and save over a trillion dollars in costs.

But even more fundamentally, the repeal is a win for constitutionally limited government, democratic accountability, and the rule of law. As AFPF argued in a comment supporting EPA’s proposal without taking a position on any scientific or technical issues: “EPA has used its standalone 2009 Endangerment Finding to arrogate to itself unilateral power to set national policy on a global issue—power that properly belongs to Congress alone.” The Trump EPA—unlike its predecessor—recognizes that the Finding “exceeded the agency’s authority” because the power to decide whether and, if so, how to regulate “lies solely with Congress.” That is a big deal.

The era of “trust us, we’re the agency” is over

The Supreme Court’s landmark decision in Loper Bright Enterprises v. Raimondo overruling Chevron deference played an important role in EPA’s decision. Loper Bright is cited twenty-five times in the final rule. There, EPA explains that “[a]s the Supreme Court made clear in Loper Bright,” EPA “can no longer rely on statutory silence or ambiguity to expand [the agency’s] regulatory power.” Instead, as EPA recognizes, quoting Loper Bright, “‘the scope of an agency’s own power’ is determined not by deference to asserted expertise, but by ‘the best reading of the statute,’ which is fixed at the time of enactment.” The agency concluded “the best reading” of its statutory authority under the CAA, “as informed by Loper Bright and principles of statutory interpretation, does not authorize the EPA to assert jurisdiction” to regulate “in a standalone endangerment finding.”

There is also a deeper story here. Loper Bright is not just changing outcomes; it is changing how regulations are written, justified, and defended. EPA’s Endangerment Finding repeal shows what it means to recast regulation for a post-Chevron world and is a prime example of an agency taking its duty to ascertain and respect statutory limits on its authority seriously, instead of reimagining the laws Congress passed as the agency wishes them to be. The era of “trust us, we’re the agency” is over.

It’s up to Congress to Decide

Applying the major questions doctrine—which requires Congress to clearly, not just plausibly, authorize agencies to make important policy choices—EPA independently found that it lacked legal authority to regulate for a second reason: “the Nation’s potential response to global climate change concerns is an issue that has significant economic and policy impacts, including to Americans’ basic way of life, that Congress did not clearly authorize the EPA to decide” and is therefore “a question for Congress to decide in the first instance.” In other words, the issue is of such consequence that the very question of whether to regulate—as opposed to how to regulate—should presumptively be up to Congress to decide, at least absent clear congressional authorization and subject to constitutional limits. Administrator Zeldin recently echoed this sentiment in common-sense terms, explaining the “best reading of the law” and Supreme Court precedent “makes it clear that if you’re going to regulate the heck out of greenhouse gas emissions with trillions of dollars of regulatory costs on Americans, that’s something that Congress should have a debate and a vote on.” Exactly so.

In sum, by repealing the Finding, the EPA disclaims power it has never legitimately possessed and puts it back where it belongs under our system of checks and balances: the halls of Congress. The Constitution promises that highly consequential policy choices, and the tradeoffs involved, must be made by the People’s elected representatives—not unelected bureaucrats acting alone. Whatever one thinks about the wisdom of EPA’s climate regulations, it’s up to Congress to decide whether and, if so, how to address global issues through the deliberately difficult legislative process. That is how is as it should be. And we should all celebrate the Trump EPA’s decision to respect bedrock limitations on the Executive Branch’s power by repealing the Finding.

NCLA’s “Unwritten Law” Podcast Explores Amici Arguments in Relentless

Feb 10, 2026

The New Civil Liberties Alliance’s podcast, “Unwritten Law,” has released a new episode that explores the arguments presented in seven amicus briefs recently filed at the First Circuit in Relentless v. Department of Commerce, the companion case to Loper Bright Enterprises v. Raimondo.  American for Prosperity Foundation’s brief is one of the seven discussed.

From NCLA:

In this episode of Unwritten Law, NCLA Senior Litigation Counsel John Vecchione and NCLA President Mark Chenoweth discuss a major development in NCLA’s challenge to a federal rule requiring fishermen to pay for government monitors placed on their boats—despite no clear statutory authorization.

After a district court upheld the rule using a theory that conflicts with the Supreme Court’s decision in Loper Bright, NCLA appealed to the First Circuit.  Now, seven separate amicus briefs—from across the legal and ideological spectrum—have weighed in, each highlighting a different flaw in the district court’s analysis.

John and Mark walk through the most compelling arguments from the amici, including post-Loper Bright de novo review, the misuse of “necessary and appropriate” authority, clear-statement rules, the Major Questions Doctrine, constitutional limits on agency power, and why reviving Chevron-era reasoning under new labels is not permissible.

Sixth Circuit Highlights Loper Bright’s Impact on Other Deference Regimes  

Jan 30, 2026

An interesting question after Loper Bright is how the demise of Chevron deference intersects with other deference doctrines that are still on the books, albeit perhaps on life support, such as Auer deference (which allows courts to defer to agency interpretations of their own regulations) and Stinson deference (which teaches that courts should defer to Sentencing Commission commentary on federal sentencing guidelines). 

In Niblock v. University of Kentucky, a recent Sixth Circuit decision addressing a challenge to the adequacy of the University’s sports programs under Title IX, Chief Judge Sutton, joined by Judge Murphy, authored a thoughtful concurring opinion highlighting this broader Loper Bright implementation question. The Sixth Circuit resolved this case on narrower grounds, declining to address the University’s argument that the Department of Education’s Title IX “guidance does not survive” Loper Bright and Kisor because the plaintiffs’ claims failed for other reasons. Nonetheless, the opinion—also authored by Chief Judge Sutton—noted “the many developments in administrative law since 1979” when the guidance was first issued, noting that the Sixth Circuit “has not looked at the validity of the guidance since Loper Bright and Kisor.” 

The concurrence expressed skepticism about the guidance’s validity, notwithstanding prior circuit law upholding it. This guidance was “adopted the guidance in a different world . . .  where courts routinely deferred to agency interpretations of statutes and regulations,” Judge Sutton observed, “[b]ut a lot has changed since 1979.” Citing Loper Bright, he explained that courts “no longer defer to agency interpretations of the statutes they administer” but instead “now treat all laws alike, ‘independently interpret[ing] the statute and effectuat[ing] the will of Congress subject to constitutional limits,’ without abdicating that responsibility to executive agencies.” Citing Kisor, he noted that courts “no longer lightly defer to agency interpretations of their own regulations” under Auer and thus this doctrine plays far less of a role today in statutory interpretation. 

Tying this together, Judge Sutton’s concurrence continues: 

The fate of these erstwhile deference-to-agency regimes remains linked. One reason that an agency’s interpretations of its own rules received deference under Auer was that its views of the relevant statute also received deference under Chevron. Knock out Chevron, and the scope of Auer deference narrows considerably, if indeed it remains meaningful at all. Loper Bright and Kisor should prompt us to revisit the 1979 guidance in an appropriate case. 

This point is important, underscoring Loper Bright’s broader potential significance in realigning the relationship between federal courts and the executive branch. It may well be that Loper Bright’s reaffirmation of Article III courts’ obligation to independently interpret statutes in cases involving agencies has fatally undermined the theoretical underpinnings of whatever remained of Auer deference after Kisor—and the continuing vitality of other sundry deference doctrines. And it will be interesting to see whether the Supreme Court will build on Loper Bright by squarely overruling Auer in a future decision and fully restoring Article III’s promise of judicial independence in saying what the law is.  

SCOTUS Relist

Dovetailing with Judge Sutton’s observations in Niblock on the relationship between the defunct Chevron doctrine and whatever remains of Auer, the future of Stinson deference is also in flux in the wake of Loper Bright’s overruling of Chevron. And it just so happens that the Court has before it an ideal opportunity to clarify how its decisions in Loper Bright and Kisor impact other deference doctrines. As Recasting Regulations has previously written about here and here, a now-thrice-relisted cert petition raises a related question in Poore v. United States, asking the Court to address “[w]hether the limits on agency deference announced in Kisor and Loper Bright constrain the deference courts may accord the Sentencing Commission’s interpretation of its own rules via commentary.” If the Court agrees to decide this case on the merits, it will provide an important opportunity to elucidate the broader meaning and significance of Loper Bright.  

AFP Foundation Files Amicus Brief in Relentless v. Department of Commerce

Jan 23, 2026

Americans for Prosperity Foundation (“AFPF”) has filed an amicus brief in Relentless v. Department of Commerce—the companion case to the historic Loper Bright Enterprises v. Raimondo.  With Loper Bright held in abeyance on remand, the outcome in Relentless may have significant implications for proper implementation of the Magnuson-Stevens Act (“MSA”), as well as the understanding of de novo review in the post-Chevron administrative‑law landscape.

A Case Shaped by Loper Bright

Relentless returns to the First Circuit following the Supreme Court’s 2024 decision in Loper Bright, which ended Chevron deference and restored to federal courts their proper role of providing independent, best readings of the law.  Because the Court vacated the First Circuit’s earlier decision upholding the legality of industry-funded monitoring in the Atlantic herring fishery, the case was sent back to the district court for reconsideration under Loper Bright’s de novo standard of review. 

Even without the benefit of Chevron deference, however, the government again prevailed.  The district court ruled the agencies’ position “reflect[ed] reasoned decisionmaking” and was consistent with their discretionary authority to implement regulations “necessary and appropriate” for the conservation of the fishery.

The District Court Failed to Undertake Meaningful De Novo Review

As AFPF’s brief explains, courts must now provide their best reading of a statute and not merely rubber-stamp a “reasonable” one advanced by an agency.  The district court in Relentless relied on its old Chevron Step Two reasoning and failed to provide an independent reading of key statutory terms like “carry,” “necessary,” and “appropriate.”  In doing so, it ignored important clarifications in the Supreme Court’s recent opinion in Seven County Infrastructure Coalition v. Eagle County.  Rather than police the boundaries of Congress’s delegation to the government, the district court assumed, without explanation, that industry-funded monitoring was the kind of measure that could be justified either as a compliance cost or something falling within the bounds of the government’s discretionary authority to implement “necessary and appropriate” rules in the fishery.

The Magnuson–Stevens Act Does Not Authorize Industry Funding

The underlying legal dispute in Relentless, like Loper Bright, turns on two provisions of the MSA: (1) Section 1853(b)(8), which permits regulators to require observers or monitors “be carried” aboard fishing vessels, and (2) Section 1853(b)(14), a residual catch-all clause that provides authority for certain “necessary and appropriate” regulations.  AFPF argues that neither provision authorizes the government to force fishermen to finance supplemental at-sea monitoring programs.

First, the original public meaning of “carry,” as used in Section 1853(b)(8), is restricted to physical conveyance and related incidental costs.  Nothing in the text or its common usage suggests Congress authorized regulators to oblige fishermen to pay monitors’ salaries, which could consume up to 20% of their returns.

Second, Section 1853(b)(14)’s “necessary and appropriate” language cannot bear the weight the government places on it.  Drawing on the Supreme Court’s 2024 decision in Harrington v. Purdue Pharma, AFPF emphasizes that catch-all provisions must be read in context.  They only provide authority for regulatory measures similar to those expressly listed in the surrounding statute—not sweeping funding mechanisms Congress never contemplated.

So What?

Allowing agencies to invent funding schemes without clear statutory authority would dangerously erode Congress’s power of the purse.  As AFPF notes, if regulators can require fishermen to pay government monitors, what stops them from imposing even more burdensome financial mandates?  The government and courts have never offered any limiting principle.

More importantly, the district court’s reconsideration of Relentless failed to engage in the sort of robust textual analysis anticipated under Loper Bright and a de novo standard of review.  The First Circuit cannot allow the lower court’s veering into arbitrary-and-capricious review, and its focus on “reasonableness,” as if Chevron were still good law, to stand.  In this sense, Relentless presents a crucial (and high-profile) test of the impact and durability of Loper Bright.

Federalist Society Event on Limits of Agency Authority

Jan 16, 2026

The Federalist Society is hosting a webinar on the “Nondelegation and the Limits of Agency Authority after Consumers’ Research and Loper Bright” next Friday, January 23 at 2:00 PM ET. Details and registration link below:

The panel will discuss the questions left open—or raised—by the Supreme Court’s decisions in FCC v. Consumers’ Research and Loper Bright Enterprises v. Raimondo, about the proper approach to statutory construction and the role that the nondelegation doctrine should play as a background principle in statutory analysis in cases where an agency has claimed broad authority to weigh competing public values when promulgating legislative rules.

Featuring:

  • Prof. Jonathan Adler, Tazewell Taylor Professor of Law and William H. Cabell Research Professor, William & Mary Law School; Senior Fellow, Property and Environment Research Center
  • Prof. Ilan Wurman, Julius E. Davis Professor of Law, University of Minnesota Law School
  • (Moderator) Adam White, Senior Fellow, American Enterprise Institute; Director, Scalia Law’s C. Boyden Gray Center for the Study of the Administrative State

Federalist Society Event on SEC Rulemaking

Jan 15, 2026

The Federalist Society is hosting a webinar on the “Loper Bright Fallout for SEC Rulemaking” next Tuesday, January 20 at 12:00 PM ET. Details and registration link below:

In an unprecedented action, the SEC in July dismissed with prejudice a pending enforcement case concerning an alleged violation of a rule promulgated under the Investment Company Act of 1940 (ICA). In 2023, the SEC had charged the defendants (a mutual fund, its investment advisor, and independent directors of the fund) with violating its 2016 “liquidity rule,” which limits the percentage of assets investment companies may hold in “illiquid” investments. The independent directors argued that the ICA did not authorize the SEC to make rules concerning fund liquidity and that its decision to do so based on a protection of investors rationale was owed no deference under the 2024 Supreme Court decision in Loper Bright.

The district court ordered supplemental briefing on Loper Bright implications, but before the SEC filed its supplemental response, it dismissed the case against all defendants, citing “policy reasons”, without more explanation.

Our panelists will discuss the numerous legal and policy issues and questions raised by this sequence of events.

Featuring:

(Moderator) Michael Piwowar, Executive Vice President, Milken Institute Finance

Jan Folena, Partner and Co-Chair of Securities & Regulatory Enforcement, Stradley Ronon

Supreme Court Conference Preview: Two Loper Bright Cert Petitions, Plus a Loper Relist

Jan 8, 2026

Tomorrow, the Supreme Court will consider for the first time two cert petitions at its conference presenting Loper Bright-related questions. A third, more tangentially Loper Bright-related petition will return as a relist.

United National Foods is Back

The petition in United National Foods, Inc. v. NLRB raises at least two Loper Bright implementation questions:

Whether Loper Bright Enterprises v. Raimondo . . .  permits a court to (a) accept an agency’s reasonable construction of a statute without exhausting all relevant tools to find the single, best meaning or (b) give precedential weight to decisions affording deference under Chevron . . . when the court evaluates different agency action.

By way of background, this case returns to the Court for a second time after United National Foods’s original cert petition was GVR’d in light of Loper Bright.  In an earlier decision, a divided Fifth Circuit panel relied on Chevron deference to uphold the authority of the NLRB’s General Counsel to unilaterally dismiss an administrative complaint after a party has filed for summary judgment, concluding the National Labor Relations Act was ambiguous on that point. On remand from the Supreme Court the same divided panel ruled once more in favor of the agency. Judge Oldham again dissented, suggesting “‘further consideration’ was an empty formality. . . .  Same reasoning, same result, different day.”  In his view, “that result conflict[s] with Loper Bright and the Supreme Court’s GVR order[.]” Should the Court grant cert, it will also have the opportunity to clarify that Loper Bright applies with full force to the NLRB’s interpretation of the NLRA, putting that arguably open question to rest.

Poore Over This Sentencing Commission Case

The petition in Poore v. United States likewise raises an important question about the applicability of the principles announced in Loper Bright:  Whether the limits on agency deference announced in Kisor v. Wilkie and Loper Bright constrain the deference courts may accord the Sentencing Commission’s interpretation of its own rules via commentary. The New Civil Liberties Alliance filed an amicus brief in support of Mr. Poore’s petition, underscoring the importance of the question. Recasting Regulations previously covered the Poore petition in greater detail here.

Loper Relist Watch

The Court has also relisted the petition in Tennessee v. Kennedy. Although the questions presented do not directly implicate Loper Bright, the decision below does insofar as it addresses the broader question of the scope of statutory stare decisis that applies to Chevron-era precedent after Loper Bright. That is, the decision below raises the question whether statutory stare decisis travels with the specific agency action at issue or with the agency’s interpretation of the statute. Recasting Regulations has covered this case in greater detail here.

Loper Bright Looms Large in EPA’s Exempted Renewable Fuel Reallocation Plan 

Dec 19, 2025

Earlier this month, a group of Republican U.S. Senators, led by Ted Cruz (Texas) and Mike Lee (Utah), sent a letter to the Environmental Protection Agency (“EPA”) discouraging the agency from moving forward with a proposal to reallocate exempted renewable volume obligations pursuant to the agency’s Renewal Fuel Standard program. Loper Bright figured prominently in the coalition letter and, specifically, the legislators’ argument that Congress’s failure to authorize such reallocation by statute deprived the EPA of authority to do so in the face of statutory silence.

Applying Loper Bright, Federal Circuit Upholds OPM Overtime Rule

Dec 19, 2025

AFP Foundation’s Michael Pepson mentioned Lesko v. United States as a case to watch for understanding how Loper Bright might guide restraint over agency authority without Chevron deference earlier this year. At the time, the Federal Circuit had ordered en banc review to reconsider whether the Court of Federal Claims correctly upheld the Office of Personnel Management’s (“OPM”) overtime regulations. Last week, the full Circuit ruled in favor of OPM after applying the new Loper Bright paradigm for judicial review.

DOJ Eliminates Disparate-Impact Liability from Title VI Regulations in the Wake of Loper Bright 

Dec 12, 2025

When the Supreme Court decided Loper Bright Enterprises v. Raimondo, overturning Chevron deference, it clarified the principle that federal agencies cannot extend their authority beyond what has been clearly authorized by Congress. In declaring that “statutes . . . have a single, best meaning,” the Court made clear that agencies must follow the law as written and not their policy preferences. Over the past year, this clarity has prompted many agencies to scrutinize long-standing policies, even those created before Chevron deference.  The Trump Administration has even made such reevaluation a central pillar of its deregulatory agenda, as reflected in Executive Order 14219 and guidance from the Office of Management and Budget. The Department of Justice’s (“DOJ”) new Title VI rule, which eliminates disparate-impact liability, is just one of the clearest and most recent examples of the real impact Loper Bright is having on the American regulatory space.
