No. 26-6008 (D.C. No. 5:25-CV-01221-D) (W.D. Okla.)

Before HOLMES , Chief Judge, HARTZ , TYMKOVICH , MATHESON , BACHARACH , PHILLIPS , McHUGH , MORITZ , EID , CARSON , ROSSMAN , and FEDERICO , Circuit Judges.

On February 4, 2026, the court issued its order and judgment in this matter. An active judge of the court then called a poll, sua sponte , to consider en banc review of the panel decision. Following the call for a poll, Appellant filed Appellant Kendrick Simpson’s Petition for Panel Rehearing or Rehearing En Banc (“Petition”), which wasPage 2 circulated to the en banc court. Appellees were offered an opportunity to respond to the Petition but elected not to do so.

Appellant’s request for panel rehearing is denied.

A majority of the judges in regular active service voted against en banc rehearing; the poll failed and Appellant’s request for en banc rehearing is denied. See Fed. R. App. P. 40(c). Judges Rossman and Federico voted to grant en banc rehearing.

Judge Rossman and Judge Federico have prepared the attached written dissentals from the denial of en banc rehearing. Judge Federico joins Judge Rossman’s dissental.

The Petition is DENIED. The mandate shall issue forthwith.

Entered for the Court,

Per Curiam Page 3No. 26-6008, Simpson v. Quick ROSSMAN , J., dissenting from denial of rehearing en banc .

I respectfully disagree with today's decision to deny the petition for rehearing en banc .

This capital case implicates a question that, in my view, is not settled by our circuit law or Supreme Court precedent: whether, after Exxon Mobil Corp. v. Saudi Basic Industries Corp. , 544 U.S. 280 (2005), the RookerFeldman doctrine can be triggered by a state-court decision that is not “on the merits.” Mindful of the limited circumstances in which the RookerFeldman doctrine should apply but given the many cases in which it is actually applied, this court or the Supreme Court should resolve this question of exceptional importance.

Page 4No. 26-6008, Simpson v. Quick

FEDERICO , Circuit Judge, dissenting from denial of rehearing en banc.

Kendrick Simpson was convicted of a capital crime and sentenced to death under Oklahoma law. He is scheduled to be executed next week, Thursday, February 12, 2026 at 10:00 a.m. Simpson claims the Oklahoma execution statute is unlawful because it provides prison officials “near-total discretion” in deciding the method of his execution. And, he alleges, the prison has previously used this power to torture a man to death. In an attempt to avoid this fate, Simpson sought recourse in Oklahoma's courts. But the Oklahoma Court of Criminal Appeals (OCCA) found his claim had not ripened and declined to decide its merits.

So, Simpson filed an original action in the Western District of Oklahoma. Invoking 42 U.S.C. § 1983, he alleged that OCCA’s refusal to hear his claim violates his rights under the United States Constitution. The district court applied the Rooker -Feldman doctrine and dismissed his case.¹ But that cannot be correct. Had OCCA decided the merits of Simpson’s challenge, the district Page 5court, and now this court, could surely hear his case. See Reed v. Goertz , 598 U.S. 230 (2023); Skinner v. Switzer , 562 U.S. 521 (2011). There is no reason, in jurisprudence or common sense, that federal courts must abstain from hearing his due process challenge to the state court’s jurisdictional rule.

Nonetheless, a panel of this court affirmed the district court’s dismissal. In so doing, this court expanded a doctrine that the Supreme Court will soon consider overruling. See Brief for Petitioner at § II, T. M. v. Univ. of Md. Med. Sys. , No. 25-197 (U.S. Jan. 14, 2026) (certiorari granted; argument presented in alternative). To reach its holding, this court worked hard to distinguish three recent Supreme Court cases that all point the other direction, and then relied on an unpublished out-of-circuit case that cannot be squared with either our caselaw or that of the Supreme Court. Now, Simpson faces execution without an opportunity to vindicate his claims alleging violations of his constitutional rights.

Because Simpson's case presents “an issue of exceptional public importance” and the panel’s Order conflicts with the opinions of the United States Supreme Court and our circuit, we should rehear it before the en banc court. See 10th Cir. R. 40.1(B); accord Fed. R. App. P. 40(b)(2). I respectfully dissent.

Page 6This proceeding stems from crimes that were committed two decades ago. Simpson went to a nightclub and got into an argument with two men. An adversary hit him, and Simpson left the club. But when he saw them later the same night, Simpson shot and killed both men. The state charged him with two counts of first-degree murder, and a jury convicted, finding four aggravating circumstances. Simpson was sentenced to death.

From death row, Simpson sought relief in Oklahoma’s courts. In that litigation, he brought a facial challenge to the Oklahoma statute authorizing executions. His challenge took the form of an action for injunctive and declaratory relief on the theory that the execution statute violates the Oklahoma Constitution. The statute provides four methods of execution: lethal injection, nitrogen hypoxia, electrocution, and firing squad. Okla. Stat. tit. 22, § 1014. The statute lists the methods in order and allows prison officials to bypass a method if it is either unconstitutional or 'unavailable.' See id. Simpson argued that because the statute does not define unavailability, it creates an unlawful delegation of legislative power prohibited by the Oklahoma Constitution.

Simpson highlighted some of the prison's previous determinations of unavailability. He pointed to the execution of Charles Warner, who died by lethal injection. In the pleadings, Simpson alleged that the prison used the Page 7wrong drugs. Warner’s last words were: “My body is on fire.” R. at 23. Simpson alleged that this demonstrates “[t]he prison tortured a man to death because it failed to find that lethal injection was unavailable.” Id.

OCCA, though, found Simpson’s claim was not ripe. It reasoned: “Unless and until lethal injection is held unconstitutional by a court or is otherwise unavailable, there has been no harm” to Simpson. Underwood v. Harpe , No. PR-2024-637, slip op. at 3 (Okla. Crim. App. Sept. 17, 2024). Notably, OCCA’s order was filed before Simpson’s execution date was set.

Next, Simpson filed his original action in federal court, in the Western District of Oklahoma. There, he argued that he was subjected to a 'state process [that] singled out the execution statute as the one statute that cannot be challenged before enforcement.” R. at 17. He alleged that although state law provides for pre-enforcement challenges to the constitutionality of statutes, the construction of state justiciability doctrines uniquely prohibits such challenges to the execution statute. Simpson explained: 'Before execution, the case is unripe. After execution, the case is moot. Any challenge to the statute goes Page 8from unripe to moot instantaneously.” Id. at 21.² This, he argued, denied his rights to procedural due process, judicial access, and equal protection under the United States Constitution.

The district court applied the Rooker -Feldman doctrine and Eleventh Amendment immunity to conclude that it did not have jurisdiction over the case. Simpson timely appealed to this court, and a panel of this court affirmed. In my view, this affirmance should be examined by the en banc court. Given that this court has declined further review, I hope this case garners a hard look by the Supreme Court.

For all the judicial ink that has been spilled in its name, Rooker -Feldman is at least theoretically straightforward. The doctrine merely acknowledges the statutory edict that direct appeals from a state’s highest court may only be Page 9heard in the Supreme Court of the United States. Verizon Md., Inc. v. Pub. Serv. Comm’n of Md. , 535 U.S. 635, 644 n.3 (2002) (citing 28 U.S.C. §§ 1257, 1331); see also Campbell v. City of Spencer , 682 F.3d 1278, 1281 (10th Cir. 2012) (“[W]hen Congress vested the Supreme Court with appellate jurisdiction over state-court judgments, it implied that the lower federal courts lacked authority to review state-court judicial proceedings.'). But, some have observed that instead of hewing to this narrow path, federal district and circuit courts seized on Rooker -Feldman ’s potential as a “‘docket-clearing workhorse’” and transformed it into “an inscrutable abstention doctrine, an untethered way for federal courts to defer to state court litigation of related cases and controversies and a new way to avoid deciding federal questions.” VanderKodde v. Mary Jane M. Elliott, P.C. , 951 F.3d 397, 406 (6th Cir. 2020) (Sutton, J., concurring) (quoting Susan Bandes, The Rooker-Feldman Doctrine: Evaluating Its Jurisdictional Status , 74 Notre Dame L. Rev. 1175, 1175 (1999)).

In 2005, the Supreme Court, apparently concerned by the doctrine's expansion and frequent usage in district and circuit courts, issued Exxon Mobil Corp. v. Saudi Basic Industries , 544 U.S. 280 (2005). There, the Court provided the modern formulation of the doctrine:

The Rooker -Feldman doctrine, we hold today, is confined to cases of the kind from which the doctrine acquired its name: cases brought by state-court losers complaining of injuries caused by

Page 10state-court judgments rendered before the district court proceedings commenced and inviting district court review and rejection of those judgments.

Id. at 284.

In applying this standard, we 'follow the Supreme Court's lead' and require that 'an element of the claim [] be that the state court wrongfully entered its judgment.” Campbell , 682 F.3d at 1283. 'Thus, a federal-court claim is not barred by Rooker -Feldman as a complaint 'of injury caused by a statecourt judgment’ just because it seeks relief inconsistent with that judgment.” Id. (alterations adopted and internal citation omitted) (quoting Exxon , 544 U.S. at 284). So, where a federal complaint “does not challenge the adverse [state court] decision[]” but instead “targets as unconstitutional the [state] statute [] authoritatively construed,” it faces no Rooker -Feldman bar. Skinner , 562 U.S. at 532. Even though the state court decision itself may be unreviewable, “a statute or rule governing the decision may be challenged in a federal action.” Id.

We have apparently never applied Rooker -Feldman in an analogous case to bar review of a state court judgment that did not address the merits of the Page 11claim.³ There is good reason to think we should not do so now. A state court's jurisdictional determination may have preclusive effect, but Rooker -Feldman is distinct from preclusion. Exxon , 544 U.S. at 293; Mayotte v. U.S. Bank Nat’l Ass’n , 880 F.3d 1169, 1174 (10th Cir. 2018) ; Campbell , 682 F.3d at 1283. And it is the law of this circuit that Rooker -Feldman does not bar challenges to postjudgment state enforcement procedures. Graff v. Aberdeen Enterprizes, II, Inc. , 65 F.4th 500, 517 (10th Cir. 2023) (citing Kiowa Indian Tribe of Okla. v. Hoover , 150 F.3d 1163, 1171 (10th Cir. 1998)).

More to the point is our opinion in Merrill Lynch Business Financial Services, Inc. v. Nudell , where this court held that the Rooker-Feldman doctrine is inapplicable when a state court does not pass on the merits of the claim. See 363 F.3d 1072, 1076 (10th Cir. 2004) (citing Pittsburg Cnty. Rural Page 12Water Dist. No. 7 v. City of McAlester , 358 F.3d 694, 707 (10th Cir. 2004)).⁴ Because this case predated Exxon , we did not apply the now-operative standard. Instead, we applied the “inextricably intertwined” standard that the Supreme Court eschewed in its Exxon reformulation. See Campbell , 682 F.3d at 1283.

However, our analysis in Merrill Lynch did not rely solely on a determination that the state and federal claims were not 'inextricably intertwined.” See 363 F.3d at 1075-76. Instead, we made the threshold determination that no issue was 'actually decided' in state court and, therefore, the dismissal “not on the merits” did not “trigger” application of the 'inextricably intertwined' analysis. See id. at 1076. Thus, our subsequent reasoning in Campbell that we need not 'untangle the meaning of inextricably intertwined,' see 682 F.3d at 1283, does little to unmoor Merrill Lynch from its foundations. Even though it predates Exxon , this court has not explicitly overruled Merrill Lynch , so it may still be good law for the proposition that a state court's non-merits determination does not bring Rooker-Feldman into Page 13play. To the extent there is any doubt, this court should have considered the question en banc.

And recent Supreme Court jurisprudence reinforces this teaching. Thrice in recent memory the Court has reviewed challenges to a Texas postconviction DNA statute: Skinner ; Reed ; Gutierrez v. Saenz , 606 U.S. 305 (2025). All three of those challenges were, like this case, § 1983 suits brought in federal district court after Texas state courts reviewed and denied the defendants’ claims on the merits. Yet, in none of those cases did the Supreme Court find RookerFeldman to be a jurisdictional bar. To the contrary, the Supreme Court explicitly held in two of those cases that Rooker-Feldman did not apply. See Reed , 598 U.S. at 235; Skinner , 562 U.S. at 532 . These three cases demonstrate that if OCCA had decided on the merits whether the Oklahoma execution statute comports with the state constitution, then Simpson’s federal complaint would suffer no Rooker-Feldman bar. It is hard to see why a state rule of justiciability should be any less amenable to review than the “authoritative[] constru[ction]' of a statute, see Skinner , 562 U.S. at 532. Indeed, both statutes and “rule[s] governing the decision may be challenged in a federal action.” Id. The Rooker-Feldman doctrine may be appropriately invoked where a losing party seeks to appeal a state court judgment to a federal district and then circuit court. But it does not insulate from review on federal grounds a state court rule that prevents access to a state court determination in the first place.

Page 14Simpson’s federal complaint alleges that OCCA has applied its ripeness doctrine to render the execution statute unreviewable. R. at 17. In so many words, he argues that this “rule governing [the state court] decision,” Skinner , 562 U.S. at 532, prevents him from ever having access to a forum for his claim. Simpson “does ‘not challenge the adverse’ state-court decisions themselves, but rather ‘targets as unconstitutional the [Oklahoma doctrine] they authoritatively construed.’” Reed , 598 U.S. at 235 (quoting Skinner , 562 U.S. at 532). And these allegations are not in service of a request to merely revisit the state court judgment. They support an original federal action under 42 U.S.C. § 1983 alleging violations of Simpson’s constitutional rights. Simpson’s federal claims are outside the scope of Rooker-Feldman .

Resisting this conclusion, the panel cites to an unpublished per curiam disposition of our sister circuit: Rhoades v. Martinez , No. 21-70007, 2021 WL 4434711 (5th Cir. 2021). But the reasoning, which was joined by only two of the Fifth Circuit panel’s three judges, see id. at n*, does not translate.

In Rhoades , the Fifth Circuit distinguished Skinner because Rhoades had named as defendant a state judge, not a district attorney. Id. at *2. It acknowledged this distinction as 'fundamental.' Id. And in this case, of course, Simpson has named no judge as defendant. Even setting that difference aside, Rhoades cannot be squared with our precedent or that of the Supreme Court. Although the Fifth Circuit reasoned that a challenge to a jurisdictional Page 15determination “cannot be reframed as a denial of due process rooted in the state law rule,” it failed to explain how it reached that conclusion. Id. And, rather than applying the rule announced in Exxon , the Fifth Circuit cited to preExxon caselaw for the 'inextricably intertwined' standard. Id.

In Campbell , this court recognized that Exxon changed the standard we must apply when considering whether a claim is barred by Rooker -Feldman, and thereafter we dropped the “inextricably intertwined” consideration from our jurisprudence. 682 F.3d at 1283. But Rhoades explicitly applies the “inextricably intertwined” standard that this court has said no longer applies. The panel’s decision makes no mention of this aspect of Rhoades and, in my view, simply gives Rhoades more weight than it can bear.

I fear that we have departed from the precedent of this court and, more importantly, from the binding precedent of the Supreme Court. As I understand it, the Supreme Court has already given authoritative guidance on how the doctrine applies. Of course, the Supreme Court looks upon Rooker -Feldman from a far different vantage point than we do. But from where I sit, precedent compels reversal.

And certainly, this matter is of exceptional public importance – Simpson is set to be executed next week. Given the reasons explained above, I respectfully dissent from denial of en banc review.
