Unpleaded Burnside and Independent Subrogation Claims Cannot Be Revived by a Pretrial Order in a Maritime Limitation Case

1. Introduction

Aries Marine v. American Longshore (5th Cir. Sept. 14, 2026) arises from the capsizing of Aries Marine Corporation’s liftboat, the L/B RAM XVII, while chartered to Fieldwood Energy, LLC for offshore platform work. Six employees of Fluid Crane & Construction, Inc. (a Fieldwood subcontractor) were aboard. Fluid’s insurer, American Longshore Mutual Association, Ltd. (“American”), paid benefits under the Longshore and Harbor Workers’ Compensation Act (“LHWCA”).

Aries filed a federal maritime limitation-of-liability proceeding seeking exoneration or limitation. Fluid and American filed a timely claim primarily aiming to obtain reimbursement. The litigation later narrowed after (1) a waiver-of-subrogation ruling (already affirmed in a prior appeal), and (2) settlements and dismissal of the limitation case. The district court allowed only a “limited motion to reopen” for any truly “live” remaining claim.

The core issue on appeal was procedural but consequential: whether Fluid and American could reopen the case to litigate (i) a general maritime negligence “Burnside” claim and (ii) Fluid’s purported “independent” subrogation claim—when those theories were not clearly pleaded and were, at most, referenced in portions of a massive proposed pretrial order.

2. Summary of the Opinion

The Fifth Circuit affirmed the denial of the motion to reopen and the motion for reconsideration. Applying abuse-of-discretion review for denials of Rule 59(e) and Rule 60(b) motions, the court held:

  • Fluid and American’s original limitation claim did not adequately plead a Burnside cause of action; the allegations read as a standard LHWCA reimbursement/subrogation claim, not a distinct tort claim.
  • The joint pretrial order did not “properly incorporate” the new theories where the district court had directed discussion of legal relationships “with reference to the claims” in a specific section—and that section contained no reference to the asserted Burnside or independent-subrogation theories.
  • Given the late stage, expired amendment deadlines, and the district court’s discretion to construe pretrial orders narrowly, the district court did not abuse its discretion in refusing to treat scattered references elsewhere in the pretrial order as adding new claims.

3. Analysis

A. Precedents Cited

1) Standard of Review for Reconsideration/Reopening

Trevino v. City of Fort Worth, 944 F.3d 567 (5th Cir. 2019) supplied the lens: denials of Rule 59(e) and Rule 60(b) motions are reviewed for abuse of discretion. That deferential standard was decisive because Fluid and American needed to show more than a plausible alternative reading of the record—they had to show the district court acted unreasonably in managing pleadings and the pretrial process.

2) The Nature of a Burnside Claim

The opinion anchors the asserted tort theory in Fed. Marine Terminals, Inc. v. Burnside Shipping Co., 394 U.S. 404 (1969), and then relies heavily on Fifth Circuit elaboration in Hartford Acc. & Indem. Co. v. Costa Lines Cargo Servs., Inc., 903 F.2d 352 (5th Cir. 1990).

Hartford is quoted for the key doctrinal separation: a Burnside claim “is entirely separate, both in nature and in origin, from an employer/carrier’s subrogation right.” It “allows an employer/carrier who has paid [LHWCA] compensation to assert a direct action in tort (or other applicable theory) against the third party or parties who caused the injury.”

That framing drove the pleading analysis: merely alleging “fault” or “negligence” as a predicate to reimbursement is not the same as pleading a direct tort claim with a duty, breach, and causation theory attributable to the vessel/operator.

3) The Function and Enforcement of Pretrial Orders

The panel placed the pretrial-order dispute within established doctrine:

  • Flannery v. Carroll, 676 F.2d 126 (5th Cir. 1982): a pretrial order clarifies “which of the claims pleaded will actually be tried,” and appellate courts are “hesitant” to interfere with a district court’s discretion; district courts are encouraged to construe pretrial orders narrowly “without fear of reversal.”
  • Rockwell Intern. Corp. v. United States, 549 U.S. 457 (2007): a pretrial order “supersede[s] all prior pleadings and control[s] the subsequent course of the action.”
  • Hodges v. United States, 597 F.2d 1014 (5th Cir. 1979): the Fifth Circuit will not deem it arbitrary for a district court to treat an unclear pretrial order as failing to provide fair notice.
  • Wilson v. Muckala, 303 F.3d 1207 (10th Cir. 2002): courts do not normally expect to see claims appear for the first time in a pretrial order, especially in cursory form, because it deprives adversaries of fair notice.

The Fifth Circuit also distinguished Homoki v. Conversion Services, Inc., 717 F.3d 388 (5th Cir. 2013). In Homoki, the amended complaint plausibly stated the claim and the pretrial order merely clarified it (even if in the wrong section). Here, by contrast, the initial claim “says nothing” about the newly asserted causes of action—so the pretrial order could not “clarify” what had never been pleaded in substance.

4) Prior Appeal in the Same Limitation Proceeding

The procedural posture mattered. The court referenced the earlier affirmance: Aries Marine Corp. v. Am. Longshore Mut. Ass'n, Ltd. (In re Aries Marine Corp.), No. 23-30564, 2024 WL 1461945 (5th Cir. Apr. 4, 2024), which upheld summary judgment enforcing a waiver-of-subrogation clause (while preserving an offset right under 33 U.S.C. § 933(f)). That history contextualized why Fluid and American later attempted to re-characterize their position as a direct tort claim (Burnside) and a distinct “independent” subrogation right.

B. Legal Reasoning

1) Why the Original Claim Failed to Plead Burnside

The panel treated pleading content, not labels, as dispositive. Fluid and American’s limitation claim sought recovery of “all damages incurred,” including reimbursement for LHWCA benefits and related expenses, and referenced “fault, negligence, or error” only in the conditional sense common to third-party reimbursement narratives.

Under Hartford Acc. & Indem. Co. v. Costa Lines Cargo Servs., Inc., a Burnside claim is a direct tort action; it requires allegations that a third party (here, Aries) owed and breached a duty causing injury—i.e., a recognizable tort theory rather than a reimbursement entitlement tethered to LHWCA compensation payments. The court emphasized Fluid and American “said nothing” about duty and breach, and their use of the word “negligence” was consistent with an LHWCA subrogation framework rather than a distinct Burnside theory.

2) Why the Pretrial Order Could Not Do the Work of an Amendment

The court accepted the general principle from Rockwell Intern. Corp. v. United States that a pretrial order supersedes pleadings. But it paired that with Flannery v. Carroll’s strong deference to district courts in “creating, enforcing, and modifying” pretrial orders—and the encouragement to construe them narrowly.

The district court had directed the parties to identify legal relationships “with reference to the claims” in a specific section. That section omitted the Burnside and independent-subrogation theories. References “buried” elsewhere, particularly after amendment deadlines had passed and where the claims were not previously asserted, did not provide adequate notice and did not “properly incorporate” new causes of action.

The Fifth Circuit’s reasoning mirrors fair-notice concerns expressed in Hodges v. United States and Wilson v. Muckala: litigation should not turn on surprise claim insertion at the pretrial stage, especially where other parties have not had a fair chance to develop defenses, discovery strategy, or dispositive motions directed to those theories.

3) The Procedural Posture Amplified Discretion

Because the appeal challenged denials of reopening/reconsideration, Trevino v. City of Fort Worth’s abuse-of-discretion standard gave the district court wide latitude. The panel’s conclusion was less that Burnside claims are hard to plead, and more that a party cannot use post-dismissal motions and an unwieldy pretrial order to resurrect (or newly create) causes of action that were not distinctly pleaded when it mattered.

C. Impact

  • Clear pleading requirement for Burnside theories in the Fifth Circuit. Parties seeking Burnside relief must plead it as a distinct direct action—identifying the duty, breach, and tort basis—rather than relying on reimbursement-style allegations typical of LHWCA subrogation claims.
  • Pretrial orders are not a safe vehicle for late-introduced claims. While pretrial orders can supersede pleadings, this decision reinforces that district courts may demand that claims be integrated in the proper, court-designated parts of the order and may reject scattered, late-stage references as inadequate notice—particularly after amendment deadlines.
  • Limitation proceedings require disciplined claim presentation. Maritime limitation actions often involve multiple claimants, insurers, contractual risk-transfer provisions (like waivers of subrogation), and settlement-driven narrowing. The decision underscores that any claimant trying to preserve alternative theories must state them plainly early, or timely amend, rather than attempt to reframe the case after dispositive rulings and dismissal.
  • Practical effect for LHWCA carriers/employers. When contractual waivers foreclose subrogation avenues (as earlier rulings did here), carriers/employers may look to Burnside-type tort claims; this opinion signals that such pivots must be made through clear pleading and timely procedural steps, not via reconsideration or pretrial-order ambiguity.

4. Complex Concepts Simplified

Limitation of liability
A maritime procedure allowing a vessel owner/operator to seek to cap liability for a casualty, consolidating claims in one forum and potentially limiting total exposure under federal maritime law.
LHWCA benefits and subrogation
The LHWCA provides workers’ compensation-type benefits for certain maritime workers. When an insurer/employer pays benefits, it may seek reimbursement from a negligent third party via subrogation—unless waived by contract.
Waiver of subrogation
A contract clause requiring a party/insurer to relinquish the right to step into the injured party’s shoes to seek reimbursement from others. Here, such a clause was central to the earlier summary judgment affirmed in 2024.
Burnside claim
A distinct, direct tort action recognized in maritime/LHWCA contexts that allows an employer/carrier who paid LHWCA compensation to sue the third party that caused the injury—separate from ordinary subrogation rights. It must be pleaded like a real tort claim (duty, breach, causation), not merely as a reimbursement request.
Pretrial order
A case-management document that sets what will actually be tried. Although it can supersede pleadings, courts enforce it to ensure clarity and fair notice—so parties cannot smuggle new claims into stray sections late in the case.

5. Conclusion

The Fifth Circuit’s decision reinforces a procedural rule with substantive bite: a Burnside negligence theory and an “independent” subrogation claim must be clearly and timely pleaded, and cannot be revived post-dismissal or effectively introduced through scattered references in a pretrial order. Relying on Hartford Acc. & Indem. Co. v. Costa Lines Cargo Servs., Inc. for the distinct nature of Burnside claims and on Flannery v. Carroll and Rockwell Intern. Corp. v. United States for pretrial-order doctrine (tempered by district-court discretion and fair-notice concerns), the court affirmed that disciplined pleading and orderly case management control—even in complex, multi-claimant maritime limitation litigation.
