Tenth Circuit: § 2255(e) Savings Clause Does Not Permit § 2241 Brady/Giglio/Napue Attacks that Fail § 2255(h)

Introduction

In Moreno v. United States (10th Cir. Feb. 20, 2026), petitioner-appellant Bani Moreno—proceeding pro se—sought to reopen federal drug-trafficking convictions by filing a 28 U.S.C. § 2241 habeas application after he had already litigated (and lost) a 28 U.S.C. § 2255 motion. He alleged that the government suppressed exculpatory and impeachment evidence—specifically sealed plea agreements of cooperating witnesses—framed as violations of Brady v. Maryland, Giglio v. United States, and Napue v. Illinois.

The dispositive issue was procedural and jurisdictional: whether Moreno’s § 2241 filing was, in substance, an unauthorized second-or-successive § 2255 motion, and whether the § 2255(e) “savings clause” allowed him to proceed under § 2241 notwithstanding § 2255(h)’s gatekeeping limits. The Tenth Circuit denied a certificate of appealability (COA) and dismissed the appeal.

Summary of the Opinion

The Tenth Circuit held that no reasonable jurist could debate the district court’s conclusion that it lacked jurisdiction because Moreno’s § 2241 application was actually a second-or-successive § 2255 motion filed without circuit authorization. The court further held that the savings clause did not apply merely because (i) the asserted factual basis was allegedly withheld earlier, (ii) the claim was “newly discovered” in a factual sense, or (iii) Moreno could not satisfy § 2255(h) due to the alleged continued suppression of the plea agreements.

The court also rejected requests to create equitable exceptions to jurisdictional constraints, and it rejected Moreno’s contention that the district court failed to conduct de novo review of objections to the magistrate judge’s recommendations.

Analysis

Precedents Cited

  • Hunnicutt v. Hawk, 229 F.3d 997 (10th Cir. 2000) (per curiam)
    Role: Supplies the baseline rule that a COA is generally not required for appeals from dismissal of a § 2241 application challenging a federal conviction. The court distinguished that baseline because one ground for dismissal here was that the filing was an unauthorized successive § 2255 motion—triggering COA requirements under later authority.
  • United States v. Springer, 875 F.3d 968 (10th Cir. 2017)
    Role: Provides the controlling procedural rule: a COA is required to appeal dismissal of a filing treated as an unauthorized second-or-successive § 2255 motion. This determines the appellate gateway and frames the court’s analysis under the COA standard.
  • Slack v. McDaniel, 529 U.S. 473 (2000)
    Role: Establishes the COA test when the district court dismisses on procedural grounds: the applicant must show reasonable jurists could debate both (i) the constitutional claim and (ii) the correctness of the procedural ruling. The panel focused on the procedural prong because the successive § 2255 characterization was not reasonably debatable.
  • United States v. Moreno, 607 F. App'x 775 (10th Cir. 2015) and United States v. Moreno, 655 F. App'x 708 (10th Cir. 2016)
    Role: Establish the litigation history: the conviction was affirmed on direct appeal and Moreno already pursued an unsuccessful initial § 2255 motion—facts necessary to label the new filing “second-or-successive.”
  • Brady v. Maryland, 373 U.S. 83 (1963); Giglio v. United States, 405 U.S. 150 (1972); Napue v. Illinois, 360 U.S. 264 (1959)
    Role: These decisions define the constitutional theories Moreno invoked (suppression of exculpatory evidence; suppression of impeachment material; knowing use of false testimony). Importantly, the panel did not reach the merits because jurisdiction was absent.
  • United States v. McKye, 947 F.3d 1293 (10th Cir. 2020)
    Role: Supplies the jurisdictional axiom: absent circuit authorization, a district court lacks jurisdiction to address the merits of a second-or-successive § 2255 motion. This is the core authority supporting dismissal.
  • United States v. Nelson, 465 F.3d 1145 (10th Cir. 2006)
    Role: Provides the definitional and functional test for classifying post-conviction filings: it is “the relief sought, not [the] pleading’s title,” that determines whether a filing is a § 2255 motion. Moreno sought to invalidate convictions as unconstitutional, so the filing was treated as § 2255 in substance.
  • Prost v. Anderson, 636 F.3d 578 (10th Cir. 2011)
    Role: Anchors the Tenth Circuit’s narrow construction of the savings clause. The panel used Prost’s framework to reject the argument that § 2255 is “inadequate or ineffective” simply because the petitioner cannot satisfy § 2255(h) or previously failed under § 2255.
  • Cleaver v. Maye, 773 F.3d 230 (10th Cir. 2014)
    Role: Reinforces multiple key propositions: § 2241 generally cannot be used to challenge the validity of an underlying conviction; unsuccessful § 2255 litigation does not make § 2255 inadequate; and the petitioner bears the burden of showing the savings clause applies.
  • Caravalho v. Pugh, 177 F.3d 1177 (10th Cir. 1999)
    Role: Supports the principle that inability to bring a second § 2255 motion due to statutory restrictions does not itself render § 2255 “inadequate or ineffective.”
  • Hale v. Fox, 829 F.3d 1162 (10th Cir. 2016)
    Role: Directly addresses the situation where the factual basis for a claim is discovered only after an initial § 2255 motion and the new claim cannot meet § 2255(h). Hale (interpreting Prost) forecloses using § 2255(e) to pursue second-and-successive collateral claims that fail § 2255(h), which the panel applied to Moreno’s withheld-plea-agreement theory.
  • McQuiggin v. Perkins, 569 U.S. 383 (2013) and Bowles v. Russell, 551 U.S. 205 (2007)
    Role: Moreno invoked McQuiggin to argue for an equitable exception. The panel rejected that path by citing Bowles for the broader rule that courts have “no authority to create equitable exceptions to jurisdictional requirements,” and by emphasizing McQuiggin concerned a first habeas application, not a second-or-successive framework.
  • Kellogg v. Watts Guerra  LLP, 41 F.4th 1246 (10th Cir. 2022)
    Role: Used to dispose of the de novo review challenge: absent concrete indications otherwise, the appellate court declined to disbelieve the district court’s express statement that it conducted the required de novo review.
  • United States v. Morgan, 346 U.S. 502 (1954)
    Role: Addresses coram nobis procedure. The magistrate judge (and district court) rejected coram nobis in this civil action because Morgan describes coram nobis as a step in the criminal case rather than a separate civil proceeding; the panel did not reach the issue because Moreno did not press it on appeal.

Legal Reasoning

  1. COA gatekeeping applied because the filing was treated as successive § 2255.
    Even though § 2241 dismissals ordinarily may be appealed without a COA, the court treated Moreno’s filing as an unauthorized successive § 2255 motion, which—under United States v. Springer—requires a COA. The COA standard from Slack v. McDaniel then controlled.
  2. Substance-over-caption classification: the petition attacked the conviction, so it was § 2255.
    Applying United States v. Nelson and the general division between § 2241 (execution/nature of confinement) and § 2255 (validity of conviction/sentence) emphasized in Prost v. Anderson and Cleaver v. Maye, the court found the relief sought was vacatur of unconstitutional convictions. That makes it a § 2255 motion, regardless of being labeled § 2241.
  3. Because an initial § 2255 had already been litigated, the new filing was second-or-successive.
    With no intervening judgment identified, the earlier unsuccessful § 2255 counted as the first, rendering the new attack successive.
  4. No jurisdiction absent authorization.
    Under United States v. McKye, the district court lacked jurisdiction to consider the merits without circuit authorization under § 2255(h). This made the procedural ruling straightforward for COA purposes: reasonable jurists could not debate it.
  5. The savings clause did not apply, even if facts were “newly discovered” and even if § 2255(h) could not be satisfied.
    Moreno argued § 2255 was “inadequate or ineffective” because he could not have raised the suppressed-plea-agreement issue earlier and still could not satisfy § 2255(h) without access to the agreements. But the panel applied the Tenth Circuit’s narrow savings clause doctrine:
    • Prost v. Anderson and Caravalho v. Pugh: inability to satisfy second-or-successive restrictions does not itself make § 2255 inadequate.
    • Cleaver v. Maye: petitioner bears the burden to show the savings clause applies.
    • Hale v. Fox: even when the factual basis emerges after the first § 2255 and the claim fails § 2255(h), Prost forecloses resort to § 2241 via § 2255(e) for such second-and-successive claims. Because Moreno conceded he could not satisfy § 2255(h), Hale effectively resolved the savings-clause dispute.
  6. No equitable workaround to jurisdiction.
    Moreno’s reliance on McQuiggin v. Perkins did not help because (i) McQuiggin concerned a first habeas petition, and (ii) under Bowles v. Russell the court lacks authority to craft equitable exceptions to jurisdictional requirements.
  7. No debatable due-process error in district court review process.
    The panel rejected the contention that the district court failed to conduct de novo review, relying on the district court’s express statements and citing Kellogg v. Watts Guerra  LLP.

Impact

Although designated as nonbinding (except for law-of-the-case, res judicata, and collateral estoppel), the order consolidates and illustrates several practically important rules in the Tenth Circuit:

  • Brady/Giglio/Napue claims do not “escape” § 2255(h) through § 2241. Even serious allegations of suppressed plea deals and witness inducements will be jurisdictionally barred if brought as a successive collateral attack without authorization.
  • The savings clause remains exceptionally narrow. The decision underscores that the Tenth Circuit’s Prost/Hale line of cases largely ties savings-clause availability to whether the claim fits within § 2255(h)’s limited exceptions—rejecting arguments based on practical inability to meet those exceptions.
  • Equity cannot cure a jurisdictional defect. Litigants seeking “equitable” exceptions to successive-motion limits face the Bowles barrier; the court will not treat fairness considerations as a substitute for statutory authorization.
  • Strategic consequence: Petitioners who discover alleged suppression after an initial § 2255 must focus on the statutory avenues (authorization under § 2255(h), or potentially relief in the criminal case where available), rather than reframing the claim as § 2241.

Complex Concepts Simplified

§ 2255 vs. § 2241
§ 2255 is the usual vehicle for a federal prisoner to attack the validity of a conviction or sentence. § 2241 generally addresses the execution of a sentence (how it is carried out), not whether the conviction itself is lawful.
Second-or-successive § 2255 motion
After one full § 2255 motion, later attempts to attack the conviction are “second-or-successive” and require advance authorization from the court of appeals under § 2255(h). Without authorization, the district court has no jurisdiction to reach the merits.
§ 2255(e) “savings clause”
A narrow exception allowing a petitioner to use § 2241 if the § 2255 remedy is “inadequate or ineffective to test the legality of his detention.” In the Tenth Circuit’s Prost/Hale framework, the clause is not triggered merely because a claim is new, hard to prove, or barred by § 2255(h).
COA (Certificate of Appealability)
A threshold permission slip to appeal certain habeas-related rulings. Under Slack, when dismissal is procedural, the petitioner must show reasonable jurists could debate the procedural ruling (and the constitutional claim).
Brady / Giglio / Napue
Brady requires disclosure of material exculpatory evidence; Giglio extends Brady to impeachment evidence (e.g., benefits promised to witnesses); Napue prohibits the knowing use of false testimony (including misleading impressions about witness deals).
Coram nobis
An extraordinary remedy typically sought in the criminal case (not a separate civil case) to correct fundamental errors when the person is no longer in custody; the panel did not address it because Moreno did not pursue that ruling on appeal.
Rule 59(e)
A motion asking the district court to alter or amend its judgment, often used to argue clear error or newly discovered matters; here it did not change the jurisdictional outcome.

Conclusion

The Tenth Circuit’s disposition in Moreno v. United States reaffirms a stringent procedural boundary: a § 2241 petition that seeks to invalidate a conviction is treated as a § 2255 motion, and when it follows an earlier § 2255 it is second-or-successive—jurisdictionally barred absent circuit authorization. It also reiterates that, under Prost v. Anderson and Hale v. Fox, the § 2255(e) savings clause does not open an alternate path simply because a petitioner alleges newly discovered Brady/Giglio material yet cannot satisfy § 2255(h). The decision’s broader significance lies in its insistence that statutory gatekeeping—rather than equitable notions of fairness—controls access to successive federal post-conviction review.
