Rule 41(b) Dismissal Without Prejudice Requires No Ehrenhaus Analysis; Frivolous, Inadequate Appellate Briefing Supports Denial of IFP and Warning of Filing Restrictions

1. Introduction

In Strege v. Launch All Nuclear Missiles (10th Cir. Mar. 24, 2026), the Tenth Circuit reviewed the District of Colorado’s dismissal, without prejudice, of pro se plaintiff Adam Strege’s action under Federal Rule of Civil Procedure 41(b) for failure to prosecute—specifically, his failure to comply with a magistrate judge’s order to cure pleading and filing-fee deficiencies within 30 days.

The case featured an unusually wide-ranging set of named “defendants,” including individuals, entities, and abstractions (e.g., “God Loves Us,” “All Planets”). The central appellate issues were procedural: (i) whether the district court abused its discretion in dismissing under Rule 41(b) without prejudice, and (ii) whether Mr. Strege should be permitted to proceed in forma pauperis (“ifp”) on appeal.

2. Summary of the Opinion

The court affirmed. It held that the district court acted within its discretion when it dismissed the case without prejudice after Mr. Strege failed to file an amended complaint on the required form and failed to pay the fees or submit a completed long-form ifp application by the deadline despite an explicit warning.

The Tenth Circuit also denied ifp status on appeal, concluding the appeal was frivolous because the opening brief did not explain any legal error and consisted largely of irrelevant, illogical, and repetitious allegations. Finally, the court warned Mr. Strege—whose prior appeals had also been deemed frivolous—that additional frivolous filings could lead to filing restrictions.

3. Analysis

A. Precedents Cited

  • James v. Wadas, 724 F.3d 1312 (10th Cir. 2013): The court reiterated the governing approach to pro se filings—liberal construction, but no judicial advocacy. This principle framed the court’s refusal to supply arguments missing from Mr. Strege’s brief.
  • Nasious v. Two Unknown B.I.C.E. Agents, 492 F.3d 1158 (10th Cir. 2007): Provided the standard of review (abuse of discretion) for Rule 41(b) dismissals and, critically, the procedural distinction that when a dismissal is without prejudice, the district court may enter the order “without attention to any particular procedures.” This authority supported affirmance without requiring an extended sanction analysis.
  • Davis v. Miller, 571 F.3d 1058 (10th Cir. 2009): Confirmed that Rule 41(b) authorizes sua sponte dismissal when a plaintiff fails to prosecute or comply with procedural rules or court orders, and that dismissals may be with or without prejudice.
  • Ehrenhaus v. Reynolds, 965 F.2d 916 (10th Cir.1992): Cited to distinguish the higher procedural burden for a with-prejudice dismissal (the five Ehrenhaus factors) from a dismissal without prejudice. The court underscored that the Ehrenhaus framework is not required here.
  • Nixon v. City & Cnty. of Denv., 784 F.3d 1364 (10th Cir. 2015): Used to emphasize appellate briefing fundamentals—an appellant must explain why the district court was wrong. Mr. Strege’s failure to do so independently supported affirmance.
  • Garrett v. Selby Connor Maddux & Janer, 425 F.3d 836 (10th Cir. 2005): The court relied on this principle that wholly inadequate briefing can “disentitle” a litigant to appellate review, even after liberal construction of pro se submissions.
  • Wisehart v. Wisehart, No. 21-1148, 2021 WL 5895130 (10th Cir. Dec. 14, 2021): Reinforced that incomprehensible, conclusory, irrelevant, and abusive briefing generally defeats meaningful appellate review.
  • Barnes v. U.S. Dist. Ct., 815 F. App'x 295 (10th Cir. 2020) (unpublished): Offered persuasive support for affirming a Rule 41(b) dismissal without prejudice based on failure to comply with an order to cure deficiencies.
  • Wheeler v. Comm'r, 528 F.3d 773 (10th Cir. 2008), and Rainey v. Bruce, 74 F. App'x 8 (10th Cir. 2003) (unpublished): Cited for the proposition that an appeal consisting of rambling, incoherent assertions can be deemed frivolous—supporting denial of ifp.
  • Pierce v. Shorty Small's of Branson Inc., 137 F.3d 1190 (10th Cir. 1998), and Carolina Cas. Ins. Co. v. Burlington Ins. Co., 951 F.3d 1199 (10th Cir. 2020): Applied to limit appellate jurisdiction to orders designated in the notice of appeal. Because Mr. Strege designated only the dismissal order, the court lacked jurisdiction to review denial of reconsideration.
  • Strege v. Comm'r, SSA, 848 F. App'x 368 (10th Cir. 2021); Strege v. Comm'r, SSA, No. 21-1311, 2022 WL 500543 (10th Cir. Feb. 18, 2022) (unpublished); Strege v. Gmail-Google, No. 24-2012, 2024 WL 3175746 (10th Cir. June 26, 2024) (unpublished): These decisions established a documented pattern of frivolous appeals, which informed the court’s renewed warning.
  • Andrews v. Heaton, 483 F.3d 1070 (10th Cir. 2007): Supported the court’s authority to impose filing restrictions after repeated frivolous filings, grounding the warning in established circuit practice.

B. Legal Reasoning

  1. Rule 41(b) authority and standard of review. The court applied abuse-of-discretion review under Nasious v. Two Unknown B.I.C.E. Agents and reaffirmed, via Davis v. Miller, that a district court may dismiss sua sponte when a plaintiff fails to prosecute or comply with a court order.
  2. Dismissal without prejudice reduces procedural prerequisites. Because the district court dismissed without prejudice, the panel relied on Nasious to hold the district court was not required to undertake any “particular procedures” (in contrast to the Ehrenhaus v. Reynolds factors applicable to dismissals with prejudice).
  3. Clear notice and noncompliance. The magistrate judge ordered Mr. Strege to (a) file an amended complaint on the proper form with a “clear and concise statement” of defendants and claims, and (b) either pay the filing fees or submit a fully completed long-form ifp application, warning dismissal would follow noncompliance within 30 days. The record showed no cure. On those facts, the dismissal was a straightforward application of Rule 41(b).
  4. Appellate waiver/forfeiture through inadequate briefing. The panel emphasized that Mr. Strege’s opening brief did not identify any error in the district court’s reasoning (Nixon v. City & Cnty. of Denv.) and was “wholly inadequate” (Garrett v. Selby Connor Maddux & Janer), leaving no developed argument to review.
  5. Jurisdictional limitation from the notice of appeal. Applying Pierce v. Shorty Small's of Branson Inc. and Carolina Cas. Ins. Co. v. Burlington Ins. Co., the court declined to review the denial of reconsideration because it was not designated in the notice of appeal.
  6. Denial of ifp for frivolous appeal. With the appeal lacking any coherent legal challenge and consisting of irrelevant, illogical content, the court deemed it frivolous (Wheeler v. Comm'r; Rainey v. Bruce) and denied ifp.
  7. Warning regarding filing restrictions. Given the pattern of frivolous appeals in Mr. Strege’s prior cases, the panel invoked Andrews v. Heaton to warn that continued frivolous filings could result in restrictions.

C. Impact

Although the disposition is an “Order and Judgment” designated as non-precedential (except for law of the case, res judicata, and collateral estoppel), it consolidates several practical, recurring procedural lessons:

  • District courts have broad discretion to dismiss without prejudice under Rule 41(b) when a plaintiff ignores clear deficiency-cure orders, and such dismissals are relatively easy to sustain on appeal because they do not trigger the heightened Ehrenhaus framework.
  • Pro se status does not relieve the obligation to brief issues coherently on appeal. A failure to explain error can effectively end the appeal without reaching the merits.
  • Repeated frivolous filings can escalate to filing restrictions. The opinion functions as a documented, incremental warning—often a precursor to restrictions in later cases.
  • IFP is not a vehicle for meritless appeals. The decision reinforces that frivolousness forecloses ifp status.

4. Complex Concepts Simplified

Rule 41(b) dismissal for failure to prosecute
A court may dismiss a case when the plaintiff does not move the case forward or disobeys court orders (for example, failing to file required documents or fix deficiencies by a deadline).
“Without prejudice” vs. “with prejudice”
“Without prejudice” means the case is dismissed but can generally be refiled. “With prejudice” means the case is ended permanently. Because a with-prejudice dismissal is harsher, courts typically must consider additional factors (the Ehrenhaus v. Reynolds factors in the Tenth Circuit).
In forma pauperis (ifp)
Permission to pursue a case or appeal without paying filing fees due to inability to pay. Courts may deny ifp when an appeal is frivolous (lacking any arguable legal or factual basis).
“Frivolous” appeal
An appeal that offers no meaningful legal argument or factual basis—often characterized by irrelevant, incoherent, or purely conclusory assertions.
Notice of appeal limits appellate jurisdiction
The appellate court typically reviews only the judgments or orders the appellant identifies in the notice of appeal. If an order is not designated, the appellate court may lack jurisdiction to review it.
Filing restrictions
Court-imposed limits on a litigant’s ability to file new actions or appeals without prior permission, typically used to address repeated frivolous or abusive filings.

5. Conclusion

The Tenth Circuit’s decision affirms a straightforward application of Rule 41(b): when a plaintiff, even a pro se litigant, receives clear instructions and a clear warning but fails to cure deficiencies, a dismissal without prejudice is well within the district court’s discretion and does not require a detailed Ehrenhaus sanction analysis. On appeal, the court reinforced that inadequate, incoherent briefing can forfeit meaningful review and support a finding of frivolousness, justifying denial of ifp status and a warning that continued frivolous litigation may lead to filing restrictions.
