EPA Green Bank En Banc Ruling Leaves Forum Question Open

Last verified: August 5, 2026, 00:00 UTC. Case: Climate United Fund v. Citibank, N.A., D.C. Circuit Nos. 25-5122 and 25-5123. Primary materials checked: the D.C. Circuit docket entries for the August 4, 2026 en banc judgment and related clerk’s stay order, and the September 2, 2025 panel opinion that was later vacated when rehearing en banc was granted. This record is for litigation tracking and court-obligation analysis, not legal advice.

The short answer for anyone briefing the EPA green bank appeals ruling is this: the D.C. Circuit’s August 4 en banc disposition keeps alive the core protection barring EPA from terminating the green bank grants, but it does not finally settle, as binding D.C. Circuit law, whether the broader grant-clawback disputes belong in district court or in the Court of Federal Claims. The court affirmed paragraph two of Judge Tanya Chutkan’s April 15, 2025 preliminary injunction, the anti-termination paragraph. The remaining injunctive relief was affirmed without a memorandum opinion by an equally divided en banc court, according to the docket language and the court’s Rule 40(d) procedure cited there.[1]

That distinction is the point. A practical victory for these grantees is not the same thing as a precedential answer for the next federal grant recipient whose award is frozen or terminated. For a disposition-focused sibling record on what the en banc court did to the injunction itself, see What the en banc court held in the EPA green bank clawback suit. This article tracks the narrower forum question: what lawyers can safely say the D.C. Circuit established.

The disposition preserved relief, but only part of the ruling carries ordinary precedential force

The August 4 docket entries matter more than the shorthand. They show a split treatment of Judge Chutkan’s April 15 preliminary injunction. Paragraph two, the paragraph barring termination of the grants, was affirmed. The rest of the relief was affirmed by an equally divided court without a memorandum opinion under the D.C. Circuit’s en banc procedure.[1]

The no-precedential-weight conclusion for the equally divided portion should be stated as a procedural inference from that docket language and D.C. Cir. R. 40(d), not as a separate reasoned holding by the court. An equally divided affirmance resolves the judgment before the court. It does not provide a majority rationale that district courts, agencies, or later D.C. Circuit panels can quote as the circuit’s answer to the Tucker Act question.

That is why the case is both highly important and easy to overstate. The grantees keep the anti-termination protection. The D.C. Circuit did not leave EPA free to end the awards on the spot. But the en banc court also did not produce a majority opinion holding that APA-style prospective relief for federal grant recipients is available in district court despite the Tucker Act.

The vacated panel opinion remains the best map of the government’s forum theory

The September 2, 2025 panel decision did give EPA the kind of forum ruling the government wanted. Judge Neomi Rao, joined by Judge Gregory Katsas, treated the grantees’ claims as contract claims governed by the Tucker Act, placing them in the Court of Federal Claims rather than in district court. The panel majority also rejected the grantees’ constitutional theory as meritless.[2]

On the panel’s account, the plaintiffs were not really asking a district judge to police unlawful agency action in the ordinary APA sense. They were seeking to enforce payment and performance obligations under grant agreements. If that characterization controls, the Tucker Act does the forum work: the Court of Federal Claims hears the money claim, and district-court injunctions preserving grant access become suspect because they function as contract enforcement by another name.[2]

That panel judgment no longer governs. Rehearing en banc, granted on December 17, 2025, vacated the panel judgment. The majority opinion’s forum holding therefore should not be described as D.C. Circuit precedent after en banc review. It is still useful because it states, cleanly and forcefully, the theory EPA and other agencies can be expected to press in grant-termination cases. It is not a holding later litigants can cite as controlling circuit law.

Pillard’s dissent explains the stakes, but it is not the holding either

Judge Cornelia Pillard’s panel dissent is the sharpest account of the grantees’ forum position. She objected to what she called a “misguided and breathtakingly expansive conception of the Tucker Act,” and warned that the majority’s approach would let the government seize funds based on “spurious and pretextual allegations” while forcing grantees into a damages forum unable to preserve ongoing program access.[2][3]

For grant recipients, that distinction is not academic. A lump-sum damages remedy after the fact does not necessarily keep a financing program alive, preserve counterparties, or prevent the downstream consequences of a frozen award. Pillard’s dissent gives lawyers the developed answer to EPA’s contract-channeling theory: the plaintiffs were seeking prospective relief against allegedly unlawful agency action, not merely compensation for a broken promise.

But the dissent should be used with the same discipline as the vacated majority. It is an argument source, not a circuit holding. After the en banc disposition, neither the panel majority’s Tucker Act rule nor the panel dissent’s district-court rule emerged as the D.C. Circuit’s binding answer.

EPA’s “simple contract fight” framing remains the cleanest opposing theory

EPA’s procedural pitch has been straightforward: this is a contract dispute over grant agreements, and the proper forum is a court that can award a lump sum, not a district court ordering the government to keep grants in place. The Associated Press described that as the administration’s “simple contract fight” framing in its report on the August 4 ruling.[4]

That position gains force whenever the requested relief looks like payment control. It becomes harder when plaintiffs characterize the government’s conduct as agency action taken for reasons outside the grant terms, or as an attempt to use termination machinery to accomplish a policy reversal Congress did not authorize. The hard cases are the ones in between: grant terms exist, agency discretion exists, and the remedy sought is prospective enough to look like APA relief but financial enough to trigger Tucker Act objections.

Climate United is valuable because it puts that conflict in a clean posture. It does not remove the conflict. The en banc court’s split means neither side can honestly say the D.C. Circuit has now adopted its forum theory for the broader federal grant-termination wave.

The Supreme Court’s NIH emergency signal helped shape the panel, not this en banc holding

The panel did not write on a blank slate. In August 2025, the Supreme Court’s emergency order in American Public Health Association v. NIH signaled that challenges to federal grant terminations may belong in the Court of Federal Claims, and that signal framed the D.C. Circuit panel’s treatment of the EPA green bank dispute.[5]

The word “signal” is doing work here. An emergency order can affect lower-court behavior without supplying a merits opinion that answers every remedial and forum question in later cases. The Rao panel followed the direction it understood from the NIH order. The en banc court then failed to produce a majority rationale that converted that direction into a D.C. Circuit rule for the EPA grants.

The funding figures are large, but the legal question is narrower

The panel opinion described the dispute as involving roughly $20 billion across eight National Clean Investment Fund and Clean Communities Investment Accelerator grantees. It identified Climate United’s award as $6.97 billion, Coalition for Green Capital’s as $5 billion, and Power Forward Communities’ as $2 billion.[2]

Those figures sit inside the Inflation Reduction Act’s broader green bank structure, but the statutory and program background should not obscure the procedural issue. Citibank’s role as financial agent, the architecture of climate finance, and the politics of the Greenhouse Gas Reduction Fund all matter to the program. For litigation teams, the immediate question is whether an allegedly unlawful freeze or termination can be stopped in district court before the program architecture collapses, or whether the recipient must proceed in the Court of Federal Claims after the fact.

The repeal wrinkle may matter, but it does not supply the missing forum rule

The One Big Beautiful Bill Act repeal issue belongs in the record because it appears to have affected at least some judges’ views of prospective access to funds. AP reported that one of the six judges in the reported 6-4 split said repeal complicated whether grantees could access funds going forward, while the four judges siding with EPA said the repeal gave the agency authority to end the grants.[4]

That reporting is useful but not a substitute for the docket-confirmed disposition. The precise vote alignment should be checked against separately filed opinions as they are reviewed. AP’s account of six judges and Climate United’s reported statement that five judges voted to affirm can be reconciled with a 6-4 affirmance of the termination bar and a 5-5 equally divided affirmance of the remaining relief, but the operative legal treatment should be tied to the court’s own entries rather than to advocacy summaries or press framing.[1][4]

Why this matters beyond EPA’s green bank grants

The same forum dispute is appearing across the grant-clawback landscape. NIH termination litigation put the Supreme Court’s emergency posture into view. DOE and other grant disputes raise similar questions about when a recipient is asking for contract money and when it is asking for prospective relief against unlawful agency action. The EPA green bank litigation became the cleanest appellate vehicle because the money, the injunction, and the Tucker Act argument all arrived in one record.

The result is unsatisfying only if one expected a final circuit answer. For actual forum tracking, it is clarifying. Even after full D.C. Circuit review, the question remains open enough that parties in later cases will still need to brief it from first principles, emergency-order signals, district-court orders, vacated appellate reasoning, and the limits of equally divided affirmances.

That is also why the ruling should be read alongside the earlier forum-question record, California Rail Funding Cut Leaves the Forum Question Open. The green bank case is the natural follow-on: the D.C. Circuit got the full en banc opportunity in a major grant-termination dispute, and still did not generate a controlling forum rule for the next case.

The Solar for All parallel track is the live test to watch

The separate $7 billion Solar for All tranche is already being litigated in the Court of Federal Claims, making it a live parallel test of the government’s preferred forum for climate-grant disputes.[6]

That parallel matters because Climate United does not end the strategic choice for other recipients. A plaintiff that files in district court will face the Tucker Act channeling argument. A plaintiff that files in the Court of Federal Claims may preserve a damages path but may lose access to the kind of prospective program-preserving relief that made Judge Chutkan’s injunction consequential. The August 4 en banc judgment supplies arguments for both sides and relief for these parties; it does not remove the forum risk.

How to cite the ruling without overstating it

• Safe: The D.C. Circuit sitting en banc affirmed the anti-termination paragraph of Judge Chutkan’s April 15, 2025 preliminary injunction in Climate United Fund v. Citibank.
• Safe: The remaining injunctive relief was affirmed by an equally divided en banc court without a memorandum opinion, according to the docket entries.
• Safe: The September 2, 2025 panel opinion adopted a Tucker Act forum theory, but that panel judgment was vacated when rehearing en banc was granted.
• Unsafe: The D.C. Circuit has now definitively held that green bank grant recipients may pursue all APA-style prospective relief in district court.
• Unsafe: The D.C. Circuit has now definitively held that these grant-termination disputes belong exclusively in the Court of Federal Claims.
• Better: Climate United is the most developed appellate record on the forum fight, but its en banc disposition leaves the controlling rule unresolved for later cases.

That last formulation is the one least likely to cause trouble in a brief, client alert, or internal KM note. The ruling matters because it preserved practical relief for these grantees and because the vacated panel opinions lay out the competing forum theories in unusual detail. It is not the dispositive D.C. Circuit precedent federal-litigation teams may have hoped for, or feared.
