No Collateral-Order Jurisdiction Over Immunity Appeals When Denial Is Incident to Mediation and Without Prejudice

Introduction

Lopez v. Ramirez (5th Cir. Apr. 1, 2026) is the Fifth Circuit’s third encounter with an interlocutory posture in a First Amendment retaliation suit brought by twelve employees of the Rio Grande City Consolidated Independent School District. Plaintiffs allege they suffered demotions, reassignments, and pay cuts after publicly supporting candidates in a 2018 school-board election. They sued under 42 U.S.C. § 1983, naming three school-board members (Eduardo Ramirez, Noe Castillo, and Basilio D. Villareal, Jr.) and a former interim superintendent (Roel Gonzalez).

Defendants asserted absolute legislative immunity and, alternatively, qualified immunity, seeking dismissal. After two prior remands (because the district court denied immunity motions without analysis), the district court entered a new order: it referred the case to mediation, cancelled scheduling deadlines, and denied all pending motions—including the immunity-based motion to dismiss— without prejudice to refiling after mediation.

The key issue on this third appeal was jurisdictional: whether such a “denial without prejudice” entered as an incident to a mediation referral is an immediately appealable “final decision” under 28 U.S.C. § 1291 via the collateral order doctrine.

Summary of the Opinion

The Fifth Circuit dismissed the appeal for lack of jurisdiction. Although denials of immunity (and some refusals to rule on immunity) are often immediately appealable under the collateral order doctrine, the court held that the district court’s mediation order did not “conclusively” deny immunity. Instead, it temporarily paused the case, denied motions only to facilitate mediation, and expressly allowed the immunity motion to be refiled promptly if mediation failed. Because the order was not an appealable final decision under § 1291, the Fifth Circuit could not reach the merits.

The panel also reiterated its concern that the district court still had not provided the reasoned, individualized immunity analysis demanded by the Fifth Circuit’s prior mandates.

Analysis

Precedents Cited

  • Backe v. LeBlanc, 691 F.3d 645, 647 (5th Cir. 2012) (citing Steel Co. v. Citizens for a Better Env't, 523 U.S. 83, 94-95 (1998))
    Role in the opinion: Establishes the court’s obligation to address jurisdiction first. The Fifth Circuit invoked this as the threshold discipline: before considering immunity or procedure, it must confirm appellate jurisdiction.
  • Mohawk Indus., Inc. v. Carpenter, 558 U.S. 100, 106 (2009) (quoting Swint v. Chambers Cnty. Comm'n, 514 U.S. 35, 42 (1995))
    Role in the opinion: Provides the modern formulation of the collateral order doctrine: the order must be (1) conclusive, (2) resolve important questions separate from the merits, and (3) be effectively unreviewable after final judgment. The panel’s analysis turned primarily on the first element—conclusiveness.
  • Digital Equip. Corp. v. Desktop Direct, Inc., 511 U.S. 863, 868 (1994)
    Role in the opinion: Emphasizes the collateral order doctrine’s “stringent” conditions and narrow scope, supporting a restrained approach to interlocutory appeals even when important rights are asserted.
  • Walton v. City of Verona, 82 F.4th 314, 320 (5th Cir. 2023) (collecting cases); Helton v. Clements, 787 F.2d 1016, 1017 (5th Cir. 1986)
    Role in the opinion: These authorities recognize that typical denials of immunity—or a district court’s refusal to rule on immunity—may be immediately appealable because immunity protects against the burdens of litigation, not merely liability. The panel used them to distinguish the usual appealable immunity denial from the mediation-related, non-conclusive order here.
  • Mitchell v. Forsyth, 472 U.S. 511, 526 (1985) (quoting Harlow v. Fitzgerald, 457 U.S. 800, 816-18 (1982))
    Role in the opinion: Explains why immunity decisions can qualify for immediate appeal: immunity is a right not to stand trial (and not to bear broad discovery). If litigation burdens are imposed, the right can be irretrievably lost, making post-judgment review inadequate. The panel acknowledged this logic but concluded the mediation order did not impose those burdens in a way that “conclusively” denied immunity.
  • Lopez v. Ramirez, No. 21-40235, 2022 WL 3230442 (5th Cir. Aug. 10, 2022) (per curiam) (unpublished) (Lopez I)
    Role in the opinion: Shows the procedural history and the Fifth Circuit’s prior instruction that the district court must reassess immunity “plaintiff-by-plaintiff, defendant-by-defendant” and give reasons.
  • Lopez v. Ramirez, No. 23-40461, 2024 WL 1168048 (5th Cir. Mar. 15, 2024) (per curiam) (unpublished) (Lopez II)
    Role in the opinion: Reiterates that the district court again denied immunity “with no analysis period,” prompting a second vacatur and remand. In the 2026 decision, this history frames the panel’s frustration and its closing admonition that immunity issues should be addressed promptly and consistently with mandates.
  • Ueckert v. Guerra, 38 F.4th 446, 450 (5th Cir. 2022) (quoting State Nat. Bank of El Paso v. United States, 488 F.2d 890, 893 (5th Cir. 1974))
    Role in the opinion: Supplies language for identifying when a district court effectively “intends to have nothing further to do” with a motion. The panel used this to characterize the mediation order as the opposite: the district court signaled the motion could be renewed after mediation.
  • De Leon v. Munoz, No. 24-40215, 2025 WL 957500 (5th Cir. Mar. 31, 2025) (per curiam) (unpublished)
    Role in the opinion: The key persuasive comparator. There, a denial of a qualified-immunity motion “without prejudice to refile after mediation” was held not to be a final, unequivocal refusal to decide immunity, and thus not appealable under § 1291. The panel treated the order in Lopez as “materially indistinguishable,” driving the jurisdictional dismissal.
  • Ballard v. Burton, 444 F.3d 391, 401 n.7 (5th Cir. 2006); 5th Cir. R. 47.5.4
    Role in the opinion: Clarifies that unpublished Fifth Circuit opinions are not binding but may be persuasive—relevant because De Leon, Lopez I, and Lopez II are unpublished.

Legal Reasoning

The court’s reasoning is a tightly cabined application of § 1291 finality and the collateral order doctrine’s first requirement: conclusiveness. While the parties agreed that immunity-related orders commonly fall within the collateral order doctrine, the panel focused on a more specific question: does an order that denies an immunity motion without prejudice solely as part of a mediation referral “conclusively” determine the immunity issue?

The panel’s answer was no, for several linked reasons:

  1. The order did not finally resolve immunity. It expressly allowed refiling within seven days after mediation concluded and did not communicate an “unequivocal refusal” to decide immunity pretrial.
  2. The order functioned as a temporary pause rather than a litigation escalator. By cancelling the Rule 16 schedule and “pending setting,” the district court suspended forward litigation activity rather than forcing discovery and trial to proceed despite an immunity claim—reducing the risk that the immunity “right not to stand trial” would be irretrievably lost in the interim.
  3. This was not a “refusal to rule until trial.” Distinguishing Helton v. Clements, the panel found no indication that the district court was postponing immunity until trial; it was channeling the parties into mediation and contemplating a renewed immunity motion afterwards.
  4. Consistency with recent Fifth Circuit practice. De Leon v. Munoz provided a near-identical template: “deny without prejudice to refile after mediation” is not a final, appealable decision.

Notably, the Fifth Circuit also explained why the first two interlocutory appeals in the same litigation were different: those earlier minute-entry denials operated as conclusive rejections at the pleadings stage, forcing continued litigation without any articulated immunity ruling. The mediation-related denial, by contrast, left the door open to a prompt immunity determination after mediation and halted scheduling in the meantime.

Impact

Although unpublished, the decision reinforces a practical jurisdictional boundary in Fifth Circuit interlocutory immunity practice:

  • Mediation-first case management can defeat immediate appellate jurisdiction when the district court denies immunity motions only without prejudice and signals an intent to address immunity upon prompt refiling post-mediation. Defendants seeking an interlocutory appeal must show a conclusive denial (or an unequivocal refusal to decide) rather than an administrative pause.
  • District courts retain procedural tools to manage cases (e.g., mediation referrals and temporary denial of pending motions) without automatically triggering collateral-order review—so long as the order does not amount to a final determination or a de facto forcing of litigation burdens that immunity is designed to avoid.
  • Mandate compliance and reasoned immunity analysis remain critical. The panel’s closing footnote signals that, even if jurisdiction is absent now, continued deferral without analysis risks further appellate intervention once a truly conclusive immunity ruling is entered.

Complex Concepts Simplified

Interlocutory appeal
An appeal taken before the case ends in the trial court. Most such appeals are barred unless an exception applies.
28 U.S.C. § 1291 “final decision”
Typically, only decisions that end the case in the district court are appealable as of right.
Collateral order doctrine
A narrow exception allowing immediate appeal of a small class of orders that (1) conclusively decide an issue, (2) concern an important issue separate from the merits, and (3) would be effectively unreviewable after final judgment.
Qualified immunity
A defense that can shield government officials from suit and liability unless they violated clearly established law.
Absolute legislative immunity
A stronger immunity that can protect certain legislative acts from being challenged in court, even if allegedly unconstitutional.
“Denied without prejudice”
The motion is denied for now, but the party is permitted to file it again later; it is not a final resolution of the issue.

Conclusion

Lopez v. Ramirez establishes (at least persuasively, given its unpublished status) a clear Fifth Circuit jurisdictional rule: a district court order that denies an immunity-based motion to dismiss without prejudice as part of a mediation referral—while pausing case deadlines and contemplating prompt refiling—is not a conclusive denial and therefore is not immediately appealable under the collateral order doctrine and § 1291.

At the same time, the opinion underscores that immunity is meant to protect officials from the burdens of litigation, and it admonishes district courts to provide prompt, reasoned, individualized immunity analysis consistent with prior appellate mandates once the issue is properly re-presented.
