La. R.S. 30:29 Remediation Cases: Partial Summary Judgments on Environmental Damage/Responsibility Are Not Appealable Absent La. C.C.P. art. 1915(B) Certification (and Are Not “Declaratory Judgments” by Label)

1. Introduction

Case: WMH Farms, LLC v. Apache Corporation (Of Delaware), et al., No. 2026-C-0223 (La. May 19, 2026) (per curiam).
Parties: WMH Farms, LLC (plaintiff landowner) vs. Apache Corporation and others, including JP Oil Company, LLC (defendants/operators).
Context: A remediation action under La. R.S. 30:29 (“Section 29”), Louisiana’s statutory framework governing evaluation and remediation of environmental damage to immovable property (often in oilfield contamination disputes).

The dispute reached the Louisiana Supreme Court not on the merits of contamination, but on a threshold procedural question: whether the court of appeal had appellate jurisdiction to review a district court’s summary judgment that (i) declared environmental damage existed on the property and (ii) declared JP Oil was legally responsible—while the case still had further Section 29 steps ahead (agency plan development/review and later court adoption of a plan).

Key issue: Is such a ruling a final, appealable judgment, or an interlocutory/partial judgment that requires La. C.C.P. art. 1915(B) certification (or, alternatively, supervisory writ review)?

2. Summary of the Opinion

The Court held that the challenged summary judgment was not appealable because it was only a partial final judgment that did not dispose of the case “in whole,” and it was rendered under La. C.C.P. art. 966(E) without an express La. C.C.P. art. 1915(B) designation of finality.

  • The Third Circuit’s decision entertaining the appeal was vacated.
  • The district court’s summary judgment was reinstated.
  • The matter was remanded for further proceedings under Section 29.

The Court further rejected the defendant’s attempt to characterize the judgment as an immediately appealable declaratory judgment under La. C.C.P. art. 1871 et seq. merely because the district court used the word “declare[d]”.

3. Analysis

3.1 Precedents Cited (and How They Shaped the Holding)

Finality and Appellate Jurisdiction

  • La. C.C.P. art. 2083 and La. C.C.P. art. 1841 (general rule): Appeals lie only from final judgments that “determine the merits in whole or in part.” The Court used these provisions to frame the question as one of finality, not practical importance.
  • Quality Environmental Processes, Inc. v. Energy Dev. Corp., 16-0171 (La. App. 1 Cir. 4/12/17), 218 So. 3d 1045: cited for the proposition that a judgment partially determining the merits is a partial final judgment appealable only if authorized by La. C.C.P. art. 1915. The Court adopted this analytic pathway: determine whether the judgment is partial; then ask whether Article 1915 authorizes appeal.

Section 29’s Structure and the “True” Final Judgment in Remediation Cases

  • State v. La. Land & Expl. Co., 12-884 (La. 1/30/13), 110 So. 3d 1038: The cornerstone for understanding Section 29’s phased process. The Court relied on it to describe: (i) the factfinder’s role in determining environmental damage and responsibility; and (ii) the subsequent statutory plan-development and funding mechanism culminating in a court-adopted plan. This structure matters because it clarifies that “responsibility” findings are often not the endpoint under Section 29.
  • La. R.S. 30:29(C)(6)(a) (statutory finality rule): The Court treated this as a legislative marker for when the matter becomes appealable as of right: a judgment adopting a plan and ordering deposits for implementation “shall be considered a final judgment ... for purposes of appeal.” The Court used this to show the summary judgment at issue was not the type of Section 29 judgment the Legislature expressly made final.

Declaratory Judgments vs. Piecemeal Litigation

  • Ehlenberger v. Guardian Medical Group, LLC, 19-446 (La. App. 5 Cir. 5/29/20), 298 So. 3d 375: The Court drew heavily from Ehlenberger for two points:
    1. A declaratory judgment that only partially determines the merits is still a partial final judgment, appealable only through Article 1915.
    2. Declaratory judgment practice is generally meant to resolve controversies before coercive relief is available, not to slice issues out of ongoing litigation for early appellate review.
  • Chauvet v. City of Westwego, 599 So. 2d 294 (La. 1992); Schmill v. St. Charles Par., 96-894 (La. App. 5 Cir. 3/12/97), 692 So. 2d 1161; Reyes v. S. Envtl. of LA, 13-380 (La. App. 5 Cir. 12/19/13), 131 So. 3d 450: These cases (quoted in Ehlenberger) supplied the conceptual limits of declaratory relief and reinforced that when factual issues are involved, declaratory judgments require appropriate procedural safeguards (trial on the merits).
  • Hodgins v. Hodgins, 98-1009 (La. App. 5 Cir. 1/26/99), 726 So. 2d 466: cited (via Ehlenberger) to show that declaratory judgments embedded within ongoing suits are not automatically appealable absent Article 1915(B) designation.
  • Tyler v. Grantham, 26,678 (La. App. 2 Cir. 7/21/94), 641 So. 2d 632: used to emphasize that declaratory judgment procedure cannot be used “merely to try issues ... involved in a pending case.” This supported the Court’s rejection of the “it’s declaratory, therefore appealable” argument.
  • La. C.C.P. art. 1876: invoked to reinforce that courts may refuse declaratory relief if it would not terminate the controversy—highlighting why “declaratory” labeling should not enable piecemeal appellate review in a still-unfolding Section 29 process.

Article 1915 and the Certification Gatekeeper

  • R.J. Messinger, Inc. v. Rosenblum, 04-1664 (La. 3/2/05), 894 So. 2d 1113: cited for the modern rule: a judgment adjudicating fewer than all claims is appealable only if it fits Article 1915(A) or is certified under Article 1915(B). This case supplied the controlling framework for the Court’s jurisdictional conclusion.
  • Henry v. Reeves, 19-550, 19-456 (La. App 5 Cir. 4/28/20), 296 So. 3d 1076: provided a close analogy: a partial summary judgment on liability under La. C.C.P. art. 966(E) is not appealable without 1915(B) designation.
  • Sweet Lake Land & Oil Co., LLC, 21-169 (La. App. 3 Cir. 12/1/21), 362 So. 3d 486, writ granted in part on other grounds and remanded, 22-00497 (La. 9/20/22), 345 So. 3d 1022: cited to reinforce that partial adjudications in the Section 29 context—particularly those tied to 966(E)—require compliance with the partial-final-judgment framework.

When Interlocutory Rulings Can Be Reviewed

  • People of Living God v. Chantilly Corp., 251 La. 943, 207 So. 2d 752 (La. 1968): used for the rule that interlocutory rulings may be reviewed on appeal from a subsequent final judgment. Here, the Court pointed to Section 29(C)(6)(a)’s “plan adoption” judgment as the moment when earlier rulings (like this summary judgment) can be examined.
  • Saucier v. Waterfront E. Homeowner's Ass'n, 24-0980 (La. App. 1 Cir. 2/28/25), 406 So. 3d 1260: cited to explain the procedural safety valve: when a party improperly appeals a non-appealable interlocutory judgment, an appellate court has discretion to convert to a supervisory writ—but only if timely as a writ.

3.2 Legal Reasoning

  1. Start with the jurisdictional premise: only final judgments are appealable. The Court treated appellate jurisdiction as non-negotiable and analyzed whether the judgment met finality requirements under the Code of Civil Procedure, not whether early review would be useful.
  2. Understand the Section 29 “phases.” Section 29 requires (i) a determination of environmental damage and responsibility (by admission or factfinder), then (ii) agency plan development/review, then (iii) court adoption of an approved plan and funding orders. The Court stressed that the judgment here expressly contemplated further proceedings before the Department and the district court.
  3. Apply the Legislature’s explicit finality trigger in Section 29(C)(6)(a). A judgment becomes “final ... for purposes of appeal” when it adopts a plan and orders deposits for implementation. Because the challenged judgment did not adopt a plan, it did not qualify as the Section 29 final judgment.
  4. Reject “declaratory judgment” as an end-run around Article 1915. Even assuming the judgment “declared” rights in a way reminiscent of La. C.C.P. art. 1871, it still did not decide the Section 29 dispute “in whole,” making it, at most, a partial final judgment. Under Ehlenberger v. Guardian Medical Group, LLC, partial declaratory judgments are governed by Article 1915.
  5. Classify the ruling as a 966(E) partial summary judgment and enforce the certification requirement. The Court treated the ruling as a partial determination (environmental damage + legal responsibility) that required La. C.C.P. art. 1915(B) designation to be appealable. No designation existed, so the court of appeal lacked jurisdiction and should have dismissed the appeal.
  6. Address policy concerns raised by the court of appeal (jury trial/legislative intent) and reject them as jurisdictionally misplaced. The Supreme Court explained that defendants are not deprived of judicial review: they can (i) seek timely supervisory writs, and/or (ii) obtain review of interlocutory orders when appealing the later plan-adoption final judgment designated by Section 29(C)(6)(a).

3.3 Impact

  • Sharper limits on piecemeal appeals in Section 29 cases. Parties should expect that early “responsibility” or “damage exists” determinations—particularly via La. C.C.P. art. 966(E)—will not be appealable unless properly certified under La. C.C.P. art. 1915(B) (where applicable) or unless they fit within La. C.C.P. art. 1915(A).
  • Reduced incentive to rebrand partial summary judgments as “declaratory judgments.” The opinion discourages semantic reframing (“declare”) as a strategy to obtain immediate appellate review.
  • More reliance on supervisory writ practice for midstream review. Litigants who believe a partial summary judgment is outcome-determinative must be prepared to pursue timely writs (or risk waiting until the plan-adoption appeal stage).
  • Procedural clarity for Section 29’s appellate timing. The Court reinforces the Legislature’s chosen “appeal point” in La. R.S. 30:29(C)(6)(a), aligning remediation litigation with an orderly, staged process: judicial determination → agency plan process → court adoption/funding → appeal as of right.

4. Complex Concepts Simplified

Final judgment vs. interlocutory judgment
A final judgment is one that can be appealed as of right because it decides the merits (all or some portion authorized by law). An interlocutory ruling decides something along the way but does not end the case; it is usually not immediately appealable.
Partial final judgment
A decision that resolves some claims/issues but leaves others for later. Whether it can be appealed immediately depends on La. C.C.P. art. 1915.
La. C.C.P. art. 966(E) partial summary judgment
A summary judgment that decides a specific issue (like liability) without ending the whole case. These rulings commonly require Article 1915(B) certification to be appealable immediately.
Declaratory judgment (La. C.C.P. art. 1871 et seq.)
A procedure to declare rights/status—typically to resolve uncertainty before coercive relief is necessary. It is not intended to carve out appealable “mini-judgments” from ongoing litigation when doing so would not end the overall dispute.
Section 29 plan adoption as the appeal trigger
Under La. R.S. 30:29(C)(6)(a), the judgment that adopts the remediation/evaluation plan and orders deposits to implement it is statutorily treated as the key “final judgment” for appeal purposes in many remediation cases.
Supervisory writs
A discretionary appellate review mechanism used to challenge certain non-appealable interlocutory rulings. Timing is critical; an untimely writ request can forfeit early review.

5. Conclusion

WMH Farms, LLC v. Apache Corporation (Of Delaware) re-centers Section 29 litigation on a strict finality doctrine: a partial summary judgment determining environmental damage and legal responsibility—especially one rendered under La. C.C.P. art. 966(E)—is not immediately appealable without compliance with La. C.C.P. art. 1915. The Court also makes clear that calling such a ruling “declaratory” does not bypass the partial-judgment certification regime.

Practically, the decision channels midstream disputes into either (i) timely supervisory writ practice or (ii) later review on appeal from the statutorily recognized final judgment under La. R.S. 30:29(C)(6)(a) once a Department-approved plan is adopted by the district court. The result is a more disciplined appellate timeline in remediation cases, limiting piecemeal appeals while preserving eventual review of earlier interlocutory rulings.
