On April 5, 2021, the Supreme Court issued its decision in Google v. Oracle, ruling 6-2 in Google’s favor on the issue of fair use. So ends a decade-plus battle between two tech giants that many viewed as having the potential to reshape how computer programs are written and licensed across the software industry. Google’s win—which is plainly indebted to the amici curiae who persuaded the Court of the policy rationale for a finding of fair use—thrilled those who saw a potential win by Oracle as an existential threat to settled norms in the software industry. Others have received the decision with skepticism, questioning how the Court could have blessed Google’s verbatim copying of Oracle’s code and struggling to reconcile the result with the plain text of the Copyright Act and established fair use precedent. Now, as the dust settles, those looking to Google v. Oracle for guidance on what they can and can’t do with proprietary software they don’t own must decide what, if anything, they can draw from its holding. The answer may prove elusive, and expensive.

We’ve followed this story since the Court first granted certiorari in 2019, with posts laying out the questions before the Justices, analyzing copyrightability and fair use, and summarizing oral argument. (For those new to the subject matter, these earlier posts will help you get up to speed on this complex case.) Now, in our final post in this series, we turn to the result.

Holding

Noting that Google v. Oracle does not “overturn or modify” earlier cases involving fair use, the Court held that Google’s re-implementation of a “user interface” (i.e., 11,500 lines of declaring code from 37 Java API libraries) owned by Oracle was a fair use of that material as a matter of law.

Justice Breyer wrote the majority opinion, joined by Justices Roberts, Sotomayor, Kagan, Gorsuch, and Kavanaugh. Justice Thomas dissented, joined by Justice Alito. Justice Barrett took no part in the decision.

The Majority Opinion

Although there were two questions before the Court, the majority ignored the first, making no express ruling on whether the declaring code at issue is copyrightable. As discussed below, this omission drew sharp criticism from the dissent, and is likely to exacerbate uncertainty over how the holding in Google v. Oracle should be applied. That said, the Court implicitly sided with Oracle on this question as fair use only comes into play if the underlying work is subject to copyright; the majority also acknowledged in several places that computer programs, including the declaring code at issue here, are “subjects of copyright.” This acknowledgement, however, only makes the majority’s silence on the first question before it more conspicuous and puzzling.

Instead of addressing copyrightability under 17 U.S.C. §§ 101 and 102, the majority devotes its opinion to an analysis of the fair use factors enumerated under 17 U.S.C. § 107, ultimately ruling that each one favors Google.

Factor 2: “The Nature of the Copyright Work.” Although this factor is actually the second fair use factor, for “expository purposes” the majority considered it first.

Under this factor, the majority compared declaring code and implementing code, and identified the attributes of declaring code that distinguish it from implementing code and—per the majority—weaken its protection under the Copyright Act. For example:

  • declaring code is “inextricably bound together” with the division of computing tasks that “no one claims is a proper subject of copyright;”
  • declaring code is “inextricably bound up” with the idea of organizing tasks in a manner that is not copyrightable;
  • declaring code is “inextricably bound up” with the use of commands, i.e., method calls, that Oracle did not claim were copyrightable; and
  • declaring code is “inextricably bound up” with implementing code, which Google did not copy from Oracle.

Although these observations were all made in the context of fair use, they track the arguments Google raised in objecting to the copyrightability of declaring code under the first issue before the Court. This, again, puts a spotlight on the majority’s decision to ignore the first issue before it, and invites the question of why it didn’t simply make these observations in that context. (More on that in our discussion of the dissent.) Further elaborating on the distinction between declaring code and implementing code, the majority concludes that declaring code “embodies a different kind of creativity” in that Oracle’s code was written to attract programmers by making it easy to remember and use.

Putting these ideas together, the majority observed that although both declaring code and implementing code are “functional in nature,” declaring code is “inherently bound together” with (1) uncopyrightable ideas (task division and organization) and (2) others’ new creative expressions, like Google’s Android implementing code. The majority thus ruled that the nature of declaring code weighs in favor of fair use.

Factor 1: “The Purpose and Character of the Use.” Here the majority considered whether Google’s use added “something new, with a further purpose or different character,” altering Oracle’s declaring code. First addressing traditional concepts derived from precedent to consider whether the use was “transformative” under this factor, the majority acknowledged that Google precisely copied the code at issue, and used it “in part” for the same purpose as Oracle. This would typically cut against Google, but the majority added that, in the context of computer programs, those cannot be reasons to rule against fair use because it would improperly limit the doctrine of fair use. Thus, the majority decided that Google’s purpose was to use declaring code created for use in desktop and laptop computers and apply it to smartphones. Although the majority stopped short of ruling that all such re-implementation of declaring code will weigh in favor of fair use under this factor, it observed that the record demonstrates that re-implementing declaring code in this manner “can further the development of computer programs.” In advancing this view, the majority cited the contributions of amici supporting Google, referencing briefs submitted by Copyright Scholars, Microsoft, Computer Scientists, R Street Institute, and American Antitrust Institute. The amici convinced the majority that Google’s use was transformative under this factor.

The majority also considered the commerciality and good faith of Google’s use, finding that Google’s commercial use was not dispositive in light of its “inherently transformative” use, and expressed skepticism regarding the role Google’s alleged bad faith should play in the analysis, choosing to give it no weight. The majority found this factor weighed in Google’s favor.

Factor 3: “The Amount and Substantiality of the Portion Used.” Google copied the declaring code for 37 packages of the Sun Java API, totaling approximately 11,500 lines of code. If considered in isolation, the majority acknowledged that would be a lot of copying. But the majority declined to consider it in isolation, and instead took into account the several million lines that Google did not copy in ruling that this factor weighed in Google’s favor.

Factor 4: “Market Effects.” Here, the majority declined to consider the market effects of Google’s copying by looking at the revenue Oracle lost as a result. Instead, the majority stressed Oracle’s poor position for success in the smartphone market, and weighed it against Oracle’s claim that Google’s copying harmed it. The majority also took into account whether Google’s copying produced “public benefits” related to the Copyright Act’s concern for the “creative production of new expression.” Significantly, the majority noted that a weighing of public benefit may not always be relevant, “not even in the world of computer programs.” But it nonetheless decided to weigh them here in determining the likely market effects of Google’s re-implementation.

Somewhat confusingly, in ruling against Oracle on this factor the majority reasoned that the success of a computer program may initially be attributable to its expressive qualities, but that over time it can instead become valuable “because users, including programmers, are just used to it.” Oracle had previously warned that a ruling in Google’s favor would effectively punish it for Java’s success. And although that may be a reductive summary of the decision overall, the majority’s reasoning here raises questions as to when the success of a copyrighted work shifts from its expressive qualities to the inertia arising from wide adoption, and why that should reduce its protection under the Copyright Act. Those wondering will find little comfort in the majority’s conclusion that “given programmers’ investment in learning the Sun Java API, to allow enforcement of Oracle’s copyright here would risk harm to the public.”

The Dissent

The dissent wasted no time before taking the majority to task for its failure to address the first question before the Court, i.e., whether declaring code is copyrightable. Noting that the majority “purports to assume, without deciding, that the code is protected,” the dissent concluded that the majority’s fair use analysis is “wholly inconsistent with the substantial protection Congress gave to computer code.” The implication here is that the majority sidestepped the first question because, had it fleshed out its position, the reasoning would have made its fair use analysis untenable. Per the dissent, “the majority purports to save for another day the question whether declaring code is copyrightable” because it “cannot square its fundamentally flawed fair-use analysis with a finding that declaring code is copyrightable.”

As to the nature of the work, the dissent rejected the majority’s attempt to distinguish implementing code from declaring code, noting that each observation made by the majority about implementing code is equally true of declaring code. The dissent added that “it makes no difference” that the value of declaring code depends on how much time third parties invest in learning it because “[m]any other copyrighted works depend on the same.” The dissent illustrates this point by analogy, explaining that although a Broadway musical script needs actors and singers to invest time learning and rehearsing it “a theater cannot copy a script—the rights to which are held by a smaller theater—simply because it wants to entice actors to switch theaters and because copying the script is more efficient than requiring the actors to learn a new one.”

The dissent also took a sharply different view of the market effects of Google’s copying, noting that whether or not Oracle could have built a smartphone on its own is only “half the picture” because Oracle could have licensed its software for use in Android. According to the dissent, Google’s copying destroyed that market for Oracle: “By copying Oracle’s work, Google decimated Oracle’s market and created a mobile operating system now in over 2.5 billion actively used devices, earning tens of billions of dollars every year. If these effects on Oracle’s potential market favor Google, something is very wrong with our fair use analysis.”

On the nature of Google’s use, the dissent accused the majority of conflating transformative use with derivative use, stressing that by the majority’s logic a movie studio’s unlicensed creation of a film based on a book would be transformative.

Finally, the dissent would find Google’s use substantial because it could serve as a “market substitute” for the original.

At bottom, the dissent rejects the majority’s view that there is a sufficient difference between implementing code and declaring code to render the former more protectable than the latter. The result of the Court’s ruling, per the dissent, is that it is now “difficult to imagine any circumstance in which declaring code will remain protected by copyright.”

Standard of Review

Many observers were surprised when, in 2018, the Federal Circuit reversed the jury’s 2016 finding of fair use, and Google argued that the appellate court applied the wrong standard of review by failing to give appropriate deference to the jury’s findings of fact. Google went so far as to argue that the Federal Circuit violated the Seventh Amendment’s right to a trial by jury, which raised eyebrows when it spurred a request for supplemental briefing from the Court.

But on these procedural questions, both the majority and dissent agreed with Oracle that the Federal Circuit applied the correct standard when it treated fair use as a mixed question fact of law. The Court held that appellate courts should defer to the jury on findings of underlying fact, and then consider de novo whether those facts support fair use. Although it made no difference to the outcome here, the Court’s ruling on these questions injects more uncertainty into future litigation by making appeals from a jury’s findings on fair use more viable than they would be had the Court sided with Google on this issue.

Where Do We Go From Here?

It is tempting to view the Court’s ruling as a clear win for software developers who want to re-implement portions of proprietary computer programs without a license—i.e., much of the software industry. But the holding may prove narrower and more uncertain than it appears. That’s because any fair use analysis necessarily mixes questions of fact and law, and is often—by design—uncertain. Indeed, the majority in Google v. Oracle stressed the doctrine’s “flexible” approach to the “sometimes conflicting” aims of copyright law, and that “its application may well vary depending upon context.”

With the above in mind, consider the meandering path Google’s fair use defense took in this case. During the first trial in 2012, the jury deadlocked on fair use. In 2016, after a second trial on fair use, the jury found for Google. Then, in a rare move, the Federal Circuit reversed the jury’s finding and ruled that only one of four factors favored Google, with two of the four strongly or heavily favoring Oracle. Now, in 2021, the Supreme Court has ruled that the 2016 jury got it right, not only reversing the Federal Circuit but holding that every single fair use factor favored Google. The dissent, examining the same facts, found only one factor favored Google.

In addition, as illustrated in the chart below, the many amici who weighed in were split across factors. 39 amici addressed at least one fair use factor, but very few of the 39 addressed each of the four factors. The first factor was the most addressed factor, with 31 amici offering arguments relating to the purpose of the use, followed by the fourth factor with 26 amici addressing market effects. Although more amici argued in favor of Oracle for each of the fair use factors, the amici who argued for Google generally provided a deeper analysis of the issues relevant to fair use. This is because most Oracle-supporting amici who addressed fair use also addressed copyrightability, whereas many Google-supporting amici who addressed fair use devoted their entire briefs to fair use. Google-supporting amici also tended to focus on fewer factors, often just one or two factors, whereas Oracle-supporting amici tended to address three, if not all four, of the fair use factors. And the majority was clearly persuaded by Google-supporting amici, as it cited several of their briefs in its opinion.

Now imagine you’re a software developer who must decide whether Google v. Oracle clears the way for you to use another company’s proprietary code. How do you determine whether the code at issue is more like implementing code, which the Court did not include in its ruling on fair use, or declaring code? And assuming you can determine that the code is like the declaring code here, do you look at the result—the Court ultimately found fair use, and resoundingly so—and find comfort to proceed without a license? Or does the expensive and uncertain path of a fair use defense make you hesitant to take on that risk? After all, like Google, you may prevail, but the victory may cost more in legal fees than a license would have. Or, you might lose outright because the highly factual analysis cuts against you. For example, a court might find that your use of the code did not result in a sufficiently successful product to warrant a finding of fair use under Google v. Oracle, or that the code’s owner is better placed to compete in your market than Oracle was to compete in the smartphone market, and rule against you on that basis. Moreover, it should not be lost on anyone that Google spent many millions in legal fees, and the collective investment by the amici who filed briefs in support of Google was also significant. Query whether the same result would have been possible for a litigant without such resources to spare.

At best, in situations where the code in question is closely analogous to the declaring code at issue in Google v. Oracle, the Court’s ruling may support an efficient resolution finding fair use. But the line between implementing code and declaring code in Java—not to mention its analogues in other programming languages—may prove difficult to draw. And in those situations, Google v. Oracle is unlikely to provide the sort of certainty that can lead to efficient resolutions of copyright disputes.

Conclusion

The Court ruled that, under the doctrine of fair use, Google was free to use 11,500 lines of code from 37 Java API libraries owned by Oracle when Google programmed its Android platform. For Google, this means it will not be liable for potentially billions of dollars in damages. What it means for everyone else remains to be seen, and in light of the fact-intensive and context-specific premises behind the Court's ruling Google v. Oracle may prove narrower than it first appears.

Energy Law: Month in Review - September 2026

Welcome to Dorsey’s Energy Law: Month in Review. We provide this update to our clients to identify significant developments in the previous month. Please reach out to any of the authors, listed above, to discuss these issues. Regulatory Developments Massachusetts Ratchets Up State and Local Regulation of AI Data Centers In early September, Governor Maura Healey of Massachusetts signed an executive order requiring that artificial intelligence data centers secure the approval of local communities as a precondition to proceeding with a given project. According to the terms of the order, data center developers will need to secure a “community benefits agreement” as a precondition to receiving permits from numerous state agencies, including the Department of Environmental Protection, the Energy Facilities Siting Board, and the Massachusetts Environmental Policy Act Office. Beyond requiring community benefits agreements, the order also mandates that developers mitigate utility costs to consumers, prohibits the use of nondisclosure agreements, and requires various state agencies to develop measures to limit data center impacts on the environment. North Carolina Regulators Decline Approval of Duke Energy Gas Turbine On September 18, 2026, North Carolina Utilities Commission (NCUC) denied Duke Energy’s application for a certificate of public convenience and necessity required to construct a gas-fueled combustion turbine at its Smith Energy Complex in North Carolina. The NCUC objected strongly to the $584 million price tag and noted that Duke appeared to be constructing the facility “based on anticipated data center customer additions.” The NCUC rejected that anticipated growth as “insufficiently reliable for the Commission to act at this point.” In rejecting Duke’s application, the NCUC also noted that Duke had signed the White House Ratepayer Protection Pledge, in which it represented that it would not shift data center costs to consumers. The NCUC observed that the record did not demonstrate how Duke “intends to adhere to its commitments under the Ratepayer Protection Pledge with regard to the Proposed Facility.” Notably, commission staff had actually supported the construction of the turbine, citing concerns about Duke’s reserve margins. The NCUC noted that it “understands the Public Staff’s expressed concerns,” but those concerns were outweighed by the NCUC’s reservations, including questions of demand. Department of Energy Approves Funds for Grid Improvement The U.S. Department of Energy (DOE) recently announced that it would fund 31 grid-improvement projects in 26 states. The funding initiative is part of the DOE’s “SPARK” initiative. The funding will include $1.9 billion in federal funding from DOE and $3.35 billion in recipient cost-sharing funding. The funds will go to projects designed to improve grid reliability and lower electricity costs. Recipients plan to reconductor over 1,500 miles of transmission lines and will deploy grid-enhancing technologies across approximately 21,000 miles. DOE stated that this initiative will make available over 23 additional gigawatts of electricity. Texas Moderates Rules Governing Data Center Interconnection The Texas Public Utility Commission adopted new regulations governing large-load interconnections. The rules impose a flat study fee of $100,000 for all proposed interconnections, which departs from the initial proposal to impose study fees using a tiered system based on project size. Additionally, the final rule eliminates the PUC’s previous proposal to impose a non-refundable interconnection fee of $50,000 per MW of contracted peak demand. The final rule also moderates the initially proposed regulations governing Electric Reliability Council of Texas (ERCOT) notifications for large-load customers’ non-utilized capacity. The proposed rules would have required notifying ERCOT within 30 days of missing a scheduled energization milestone by six months. The final rules, however, do not require informing ERCOT unless a scheduled energization milestone is missed by 24 months. FERC Denies TransAlta 202(c) Cost-Recovery Plan The Federal Energy Regulatory Commission (FERC) recently rejected TransAlta’s plan to recover $19.9 million in expenses stemming from a DOE order in which DOE prohibited TransAlta from retiring its coal-powered Centralia power plant. TransAlta had previously intended to retire the facility at the end of 2025. TransAlta’s cost recovery plan proposed spending an additional $23 million on repairs to continue operating the unit. FERC’s main objection had to do with geographic scope. TransAlta’s recovery plan called for recovering costs from California Independent System Operator (CAISO) and the Southwest Power Pool (SPP), but the DOE’s order requiring operation of the plant was designed to ensure reliability in the Northwest assessment area (Montana, Oregon, Washington, and parts of northern California and northern Idaho). Accordingly, FERC was unwilling to allow cost recovery from CAISO and SPP when the order that precipitated the additional costs only related to the Northwest assessment area. FERC informed TransAlta that it would only approve cost recovery from load-serving entities in the Northwest assessment area. FERC’s decision comes amid a rush of DOE emergency orders requiring the continued operation of coal-fired generating units. Litigation Appeals Court Upholds Washington Hydropower Plant With Caveats In a September 21, 2026, opinion, the Washington Court of Appeals largely upheld a Clean Water Act water quality certification by the Washington Department of Ecology for the Goldendale Energy Storage Project, a proposed pumped-water storage hydropower system adjacent to, but off-stream from, the Columbia River. A nonprofit (Columbia Riverkeeper) and the Confederated Tribes and Bands of the Yakama Nation appealed the certification, contending that it failed to impose necessary conditions and monitoring requirements to protect the water quality of the Columbia River. Most saliently, the plaintiffs argued that the project had the potential to leak 100 acre-feet of water per year into tributaries of the Columbia River. The Court of Appeals broadly rejected plaintiffs’ challenge to the state’s conclusion that “the project was designed not to leak.” That said, the Court of Appeals did reverse on one narrow issue. Specifically, the court determined that the state’s conclusion that “leakage from the project’s tunnels would be monitored and reported” was not supported by the evidence because the certification “does not explicitly require monitoring and reporting to determine whether there is any leakage.” Accordingly, the court remanded the matter to the state to impose monitoring and reporting requirements but otherwise affirmed the certification. Legislative Developments California Legislates Restrictions on Data Center Energy Use and Grid Costs On September 21, 2026, California Governor Gavin Newsom signed seven bills broadly regulating data centers in the state. SB 1168 directed the California Public Utilities Commission to assess the energy used by data centers. It also requires the PUC to pass costs of transmission and distribution upgrades and load increases on to data centers, rather than customers. SB 886 and SB 887 compel data centers to pay for infrastructure upgrade and generation costs, and wildfire mitigation costs, in addition to imposing environmental review. The statutes additionally increase local oversight of data centers. AB 1577 imposes a monthly reporting requirement that requires data centers to supply energy consumption and efficiency data to the California Energy Commission. AB 2383 contains incentives for data centers to use onsite clean energy generation. Finally, AB 2469 and AB 2619 require data center developments to assess water supply and develop a water scarcity plan. The statutes also mandate statewide water reporting as a precondition to obtaining and renewing business licenses.

SEC Proposes Expansion of Investment Adviser Performance-Based Compensation Rule

On September 30, 2026, the Securities and Exchange Commission (the “SEC”) proposed amendments to Rule 205-3 under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), which provides an exemption from the general prohibition under Section 205(a)(1) of the Advisers Act on registered investment advisers receiving performance-based compensation (the “Proposal”) so long as performance-based compensation is limited to “qualified clients”.1 Most notably for private fund sponsors, the Proposal would expand the definition of “qualified client” to include any investors that satisfy the “accredited investor” definition under Regulation D. The Proposal may also have implications for private fund managers that rely on exemptions from investment adviser registration under state law because certain state-level investment adviser registration exemptions incorporate or otherwise reference the federal qualified client definition. Expansion of the Qualified Client Definition Under the current Rule 205-3, an investor generally may qualify as a qualified client if, among other alternatives, the investor has at least $1.4 million under management with the adviser or has a net worth exceeding $2.7 million. These thresholds are higher than the financial thresholds applicable to many accredited investors under Regulation D. As a result, an investor may currently qualify as an accredited investor for purposes of investing in a private offering without qualifying as a qualified client for purposes of paying performance-based compensation. The Proposal would expand the qualified client definition to include any natural person or legal entity investor that satisfies the accredited investor definition under Regulation D. The Proposal would also remove the assets under management and net worth thresholds under the current Rule 205-3 qualified client test. For private funds relying on Section 3(c)(1) of the Investment Company Act of 1940, this change could reduce the need to apply a separate qualified client standard to investors that already qualify as accredited investors. Dorsey Observations and Next Steps If adopted as proposed, the expanded qualified client definition could be particularly significant for private fund managers. Most private fund offerings are already limited to accredited investors under Regulation D. However, the Proposal could expand the pool of prospective investors available to emerging private fund managers while reducing the regulatory burden associated with complying with Rule 205-3. The Proposal could also benefit advisers operating below the SEC registration threshold that rely on a state private fund adviser exemption. A number of states have adopted exemptions modeled on the North American Securities Administrators Association (“NASAA”) private fund adviser exemption, which may condition relief for advisers to certain funds relying on Section 3(c)(1) on each beneficial owner satisfying the federal qualified client definition. However, state requirements vary, and any effect of the Proposal would depend on the text of the applicable state exemption and how it incorporates Rule 205-3. Many emerging private fund managers may have a larger network of accredited investor relationships than qualified client relationships during the early stages of their investment advisory business. Currently, under Rule 205-3, private fund managers may receive performance-based compensation from investors who do not satisfy the qualified client definition if those investors were admitted to their private funds prior to registration with the SEC. Following registration with the SEC, however, managers may continue to permit investors that are not qualified clients to invest in future private funds but may not receive performance-based compensation from those investors with respect to such investments. In addition, because the net worth and assets under management thresholds for qualified client status are adjusted for inflation every five years, the pool of qualified client investors may diminish over time as previously eligible investors no longer satisfy the applicable thresholds. The Proposal could provide the dual benefit of greater flexibility for private fund managers to establish and maintain relationships with accredited investors as their businesses scale and they become registered with the SEC, and greater flexibility for certain accredited investors to participate in investment strategies that historically have been restricted to much larger institutional investors. Unless and until the Proposal is adopted, investment advisers should continue to comply with the existing qualified client requirements. If the Proposal is adopted, private fund sponsors should consider whether corresponding changes are appropriate for their subscription documents, investor questionnaires, and other offering materials. Advisers that are state-registered or rely on a state-level exemption should also consult the laws and regulations of each relevant jurisdiction before changing investor eligibility standards or performance-based compensation practices, because adoption of the federal amendments may not automatically modify state requirements. Comments on the Proposal will be due 60 days after publication in the Federal Register. 1 Investment Adviser Performance-Based Compensation Modernization, Investment Advisers Act Release No. IA-7022 (Sept. 30, 2026), available at https://www.sec.gov/rules-regulations/2026/09/s7-2026-28#33-11443proposed.

The Supreme Court Update - October 8, 2026

On September 29, 2026, the Supreme Court granted certiorari in one case: Department of Homeland Security v. D.V.D., No. 26-426: This case concerns the Trump Administration’s “third-country removal” procedures, where immigrants are deported to countries not listed in the removal orders. In granting certiorari, the Court granted the Government’s application to stay a lower court decision halting the practice, which will allow third-country removals to continue pending resolution of the case. The issues presented are: (1) Whether the district court had jurisdiction over respondents’ claims; (2) whether the district court had authority to enter class-wide declaratory relief and APA vacatur under 8 U.S.C. § 1252(f)(1); (3) whether the Government’s guidance on third-country removals is unlawful under 8 U.S.C. § 1231(b), the due process clause, or FARRA/CAT and its implementing regulations; and (4) such other questions that the Government determines are appropriate for the proper disposition of the case. On October 1, 2026, the Court granted certiorari in three additional cases: Rhoney v. Barbosa da Cunha, No. 26-104: Immigration officials detained Ricardo Aparecido Barbosa da Cunha—a Brazilian citizen who had lived in the United States for approximately twenty years after entering without inspection—and denied him a bond hearing under 8 U.S.C. § 1225(b)(2)(A). The Second Circuit held that his detention was instead governed by § 1226(a), which permits release on bond, because § 1225(b)(2)(A)’s mandatory-detention requirement applies only to noncitizens apprehended while entering the country or shortly thereafter. The question presented is: Whether 8 U.S.C. § 1225(b)(2)(A) mandates the detention pending removal proceedings of aliens who, like Barbosa da Cunha, are present in the United States without having been admitted. Missionaries of St. John the Baptist, Inc. v. Frederic, No. 25-113: A Catholic religious organization sought to build a shrine to the Virgin Mary on land the organization owned adjacent to its church in Park Hills, Kentucky. Local zoning restrictions prohibited the proposed construction. The question presented is: Whether a land-use regulation that prohibits a religious institution from building a religious structure on its own property constitutes a “substantial burden” on religious exercise under the Substantial Burden Provision of the Religious Land Use and Institutionalized Persons Act, 42 U.S.C. § 2000cc(a). Marschner v. Marschner, No. 25-1349: Under the Uniformed Services Former Spouses’ Protection Act (“USFSPA”), a veteran’s longevity-based retirement pay can be divided in a divorce, but retirement pay based on disability and retirement pay that was waived to receive disability pay are indivisible. The question presented is: Does the USFSPA require state courts to refuse enforcement of indemnification provisions in a divorce settlement agreement?

EPA Limits Title V Re-Litigation of NSR Permits

Overview On September 25, 2026, the U.S. Environmental Protection Agency (“EPA”) published a final rule that significantly limits the ability of third parties to use the Clean Air Act (“CAA”) Title V permitting process to revisit New Source Review (“NSR”) permitting decisions years after those decisions were made. The rule establishes that NSR permitting determinations generally must be challenged during the original permitting proceeding, thereby providing regulated sources with greater permitting certainty and finality for major capital projects. Published in the Federal Register titled Clarifying the Scope of “Applicable Requirements” Under State Operating Permit Programs and the Federal Operating Permit Program (Docket ID No. EPA-HQ-OAR-2023-0401), the rule amends 40 C.F.R. Parts 70 and 71 to codify EPA’s interpretation regarding when requirements established under other CAA programs may be reviewed, modified, or implemented through the Title V operating permit program. The rule becomes effective 30 days after publication. The rule addresses two principal issues: (1) the relationship between NSR preconstruction permitting and Title V operating permits, and (2) the treatment of the General Duty Clause under CAA section 112(r)(1). Most significantly, the rule provides greater certainty for sources navigating the NSR permitting process. EPA’s amendments are intended to ensure that NSR permitting decisions made through an approved public process are generally not revisited later through Title V permit proceedings. The rule responds to a circuit split between the U.S. Courts of Appeals for the Fifth and Tenth Circuits. In Environmental Integrity Project v. EPA, 969 F.3d 529 (5th Cir. 2020), the Fifth Circuit upheld EPA’s interpretation, concluding that it was consistent with the text, structure, and purpose of Title V. In contrast, the Tenth Circuit reached the opposite conclusion in Sierra Club v. EPA, 964 F.3d 882 (10th Cir. 2020), finding that the then-existing regulatory definition of “applicable requirement” did not support EPA’s position. By amending the regulatory language on which the Tenth Circuit relied and codifying the interpretation approved by the Fifth Circuit, EPA has established a nationwide framework governing the interaction between NSR and Title V. NSR and Title V: EPA Establishes a Uniform Nationwide Framework At the core of the rule is EPA’s effort to define the respective roles of NSR and Title V. The rule codifies the approach EPA has applied since 2017: once a source obtains an NSR permit under an EPA-approved permitting program, and that permit was issued following public notice with an opportunity for comment and judicial review, the permit establishes the NSR-related “applicable requirements” of the State Implementation Plan (“SIP”) or Federal Implementation Plan (“FIP”) for Title V purposes. Under this framework, Title V is not a vehicle for re-examining underlying NSR permitting decisions. EPA does not intend to use the Title V process to revisit applicability determinations, emissions calculations, control technology determinations, permit conditions, or other issues resolved through the NSR permitting process. This principle applies regardless of the stage of the Title V proceeding; whether the NSR permit was issued pursuant to a SIP or FIP; the type of NSR issue involved; or whether the NSR permit is incorporated into Title V sequentially or concurrently. Limited Exceptions EPA recognizes several circumstances in which NSR issues may still be reviewed through the Title V program: No NSR permit was issued at all; The permit was issued without public notice and an opportunity for comment and judicial review; or The issue involves substantive overlap between Title V and NSR requirements, such as the adequacy of monitoring provisions. As a result, the rule does not insulate unpermitted projects or foreclose review of matters that independently arise under Title V. Key Regulatory Amendments The rule revises the definition of “applicable requirement” in 40 C.F.R. §§ 70.2 and 71.2. Paragraph (1): Where an NSR permit is issued with public notice and an opportunity for comment and judicial review, the permit establishes and defines the applicable SIP or FIP requirements for Title V purposes. Paragraph (2): All NSR permit terms, including terms contained in minor NSR permits, constitute applicable requirements that must be incorporated into Title V permits. Paragraph (4): CAA section 112(r)(1) (the General Duty Clause) is expressly excluded from the definition of “applicable requirement,” while section 112(r)(7) Risk Management Program requirements remain included. EPA also amended 40 C.F.R. §§ 70.8 and 70.12 to clarify that alleged defects in requirements established outside the Title V process generally do not provide a basis for EPA objection to a Title V permit or for a Title V citizen petition. General Duty Clause Exclusion The rule also codifies EPA’s longstanding position that the General Duty Clause in CAA section 112(r)(1) is not an “applicable requirement” for Title V purposes. EPA points to several considerations supporting that conclusion, including the distinction between the General Duty Clause and Title V permit terms, the provision’s origins in the Occupational Safety and Health Act’s general duty clause, and the different enforcement structures applicable to the General Duty Clause and Title V permit requirements. Importantly, excluding section 112(r)(1) from the definition of “applicable requirement” does not eliminate EPA’s authority to enforce the General Duty Clause independently of the Title V program. The final rule instead clarifies that the General Duty Clause need not—and should not—be incorporated into Title V permits as an applicable requirement. Practical Implications for Regulated Sources Greater Finality for NSR Permits  For projects requiring PSD, nonattainment NSR, or minor NSR permits, the permitting process becomes the primary forum for resolving disputes regarding applicability determinations, emissions calculations, control technology requirements, offsets, and permit conditions. Once an NSR permit is issued through a qualifying public process, regulated sources should face substantially reduced risk that those same issues will be challenged years later through Title V permit proceedings. Reduced Risk of Collateral Permit Challenges Stakeholders have sometimes sought to use Title V permit issuance, renewal, revision, or citizen-petition proceedings to challenge underlying NSR determinations. The final rule makes clear that Title V is not the appropriate vehicle for challenging whether an applicable requirement was correctly established in the first instance. This should reduce the risk of permit delays and uncertainty associated with collateral challenges to previously issued NSR permits. The rule does not, however, eliminate all Title V challenges relating to an NSR permit. Challenges concerning the Title V permit itself—including whether it appropriately incorporates applicable requirements or contains adequate compliance provisions—remain possible. Increased Importance of the Initial NSR Proceeding Because Title V generally will not provide a second opportunity to challenge the substantive validity of an NSR determination, the administrative record developed during the NSR process becomes increasingly important. Permit applicants should ensure that applicability analyses, emissions calculations, control technology evaluations, modeling demonstrations, and supporting technical documentation are thoroughly developed during the original permitting proceeding. For significant projects, applicants may therefore have an additional incentive to identify and resolve potential permitting issues before the NSR permit is issued rather than assuming that unresolved issues can be addressed during a subsequent Title V proceeding. Potential Incentive for Broader Public Participation EPA also notes that permitting authorities may choose to provide public notice and an opportunity for comment for a broader range of NSR permits because permits issued through a qualifying public process receive the benefit of the finality framework established by the rule. Some permitting authorities may conclude that greater public participation at the NSR stage is preferable to uncertainty during subsequent Title V proceedings. Conclusion The final rule is principally a permitting-certainty measure. For sources that obtain NSR permits through a public process, EPA has substantially limited the ability of third parties to revisit underlying NSR determinations through the Title V program. As a result, regulated entities should benefit from greater finality regarding key permitting decisions, reduced risk of collateral permit challenges, and increased certainty when planning and implementing capital projects.
