Louisiana Ports May Not Expropriate Property Solely to Lease for a Private Company’s Exclusive Use (Post-2006 “Public Purpose” Limits)

1. Introduction

In Plaquemines Port Harbor & Terminal District v. Tuan Nguyen (La. 2026-03-06), the Supreme Court of Louisiana addressed a recurring modern eminent-domain question: whether a public port authority can use Louisiana’s “quick-take” expropriation power to acquire private land primarily to lease it to a private industrial user for that user’s exclusive project operations.

The Plaquemines Port, Harbor & Terminal District (“Plaquemines Port”) sought to expropriate roughly 29 acres of unimproved immovable property owned by Tuan Nguyen, located within the footprint of the “Delta LNG Project,” a liquified natural gas and container port complex. Plaquemines Port intended to lease acquired lands to Venture Global LNG for the project’s facilities and berthing docks.

The case presented two central issues:

  • Procedural: In a quick-take expropriation under La. R.S. 19:141 et seq., what is the proper procedural mechanism to challenge “public use/public purpose”?
  • Constitutional: Does expropriation to lease property to a private company for its exclusive development and use qualify as a “public purpose” under La. Const. art. I, §4 as amended after Kelo?

2. Summary of the Opinion

The Court affirmed the trial court and the Fourth Circuit, holding that Plaquemines Port’s taking was not for a public purpose as required by La. Const. art. I, §4(B). Although public ports are listed in the constitution as a recognized “public purpose,” the Court concluded the constitution requires that the property be dedicated to use as a public port to facilitate public transportation of goods/persons in commerce—not acquired so that a private company can operate what is, in substance, a private port facility for its own goods.

The Court also rejected Plaquemines Port’s attempt to reframe Nguyen’s motion to dismiss as an exception of no cause of action; under La. R.S. 19:147, a motion to dismiss is the correct device to contest public use in a quick-take and must be tried contradictorily.

3. Analysis

3.1 Precedents Cited

Lafayette City-Parish Consolidated Government v. Lucile B. Randol Heirs, L.L.C.

The Court relied on Lafayette City-Parish Consolidated Government v. Lucile B. Randol Heirs, L.L.C., 2021-778 (La. App. 3 Cir. 8/3/22), 362 So. 3d 639, 643, writ denied, 2022-01533 (La. 12/6/22), 351 So. 3d 368, to confirm the proper procedural vehicle in a quick-take setting: a motion to dismiss under the applicable quick-take scheme—not a peremptory exception. That precedent supported the Court’s conclusion that the public-use challenge is not confined to the four corners of the petition and is instead resolved through a contradictory hearing, as the statute states.

St. Bernard Port, Harbor & Terminal District v. Violet Dock Port, Inc., LLC

The Court treated St. Bernard Port, Harbor & Terminal District v. Violet Dock Port, Inc., LLC, 2017-0434 (La. 1/30/18), 239 So. 3d 243, as the key post-2006 constitutional benchmark for port takings. It used St. Bernard Port for two propositions:

  • Method: Start with the constitutional text when evaluating “public purpose.”
  • Substance: A port taking can satisfy public purpose when it is a logical extension of port services and the taking is for continued operation as a public port even if operations are managed under a lease.

The Court distinguished this case from St. Bernard Port: there, the taking preserved and expanded the function of a public port; here, the taking was for the “sole purpose” of leasing land so the lessee could conduct its own private LNG operations and transport its own goods—making the “public port” label functionally nominal.

Kelo v. City of New London

The Court referenced Kelo v. City of New London, 545 U.S. 469 (2005), primarily as historical context for Louisiana’s 2006 constitutional amendment. It treated Kelo as the model Louisiana voters rejected: using eminent domain to transfer land between private parties for “economic development.” The Court’s interpretation of La. Const. art. I, §4 emphasized that Louisiana’s amended text is designed to prevent takings that resemble Kelo in substance, even if they are structured through public ownership plus a private lease.

Snowton v. Sewerage and Water Board; Menard v. Targa Resources, L.L.C.; Perschall v. State

These cases were cited for interpretive principles:

  • Snowton v. Sewerage and Water Board, 2008-399 (La. 3/17/09), 6 So. 3d 164: constitutional provisions are interpreted similarly to statutes.
  • Menard v. Targa Resources, L.L.C., 2023-00246 (La. 6/27/23), 366 So. 3d 1238: begin with the provision’s text.
  • Perschall v. State, 96-0322 (La. 7/1/97), 697 So. 2d 240: read words in context; courts should not adopt constructions that detract from a provision’s manifest meaning.

Together, they provided the Court’s interpretive toolkit to read “public purpose” narrowly, textually, and contextually—particularly significant because the constitution itself uses limiting language (“shall be limited to”).

State Through Dept. of Transp. and Development v. Estate of Davis

The Court invoked State Through Dept. of Transp. and Development v. Estate of Davis, 572 So. 2d 39 (La. 1990), for the rule that expropriation laws are strictly construed against the expropriating authority because they derogate from private ownership. That strict-construction stance reinforced the Court’s refusal to expand “public ports” into a general power to condemn land merely to function as a revenue-producing landlord for private industrial development.

Concurrence authorities (property-rights framing)

Justice McCallum’s concurrence cited a series of sources to underscore the primacy of property rights and the danger of diluting “public use,” including Lynch v Household Finance Corp., 405 U. S. 538 (1972); Buchanan v. Warley, 245 U.S. 60 (1917); Holden v. Hardy, 169 U. S. 366; Hawaii Housing Authority v. Midriff, 467 U. S. 229(1984); and Kelo v. City of New London, 545 U. S. 469 (2005) (including Justice Thomas’s dissent). While not the majority’s doctrinal engine, the concurrence frames the decision as part of a broader constitutional tradition requiring a genuine, demonstrable public interest, not an asserted “public utility” or revenue/job justification.

3.2 Legal Reasoning

(A) The procedural holding: La. R.S. 19:147 governs public-use challenges in quick-take

Plaquemines Port argued Nguyen’s motion to dismiss should be treated as an exception of no cause of action, limiting review to pleadings and requiring allegations be accepted as true. The Court rejected that reframing. It emphasized:

  • Plaquemines Port proceeded under La. R.S. 19:141 et seq. (quick-take).
  • La. R.S. 19:147(A) explicitly authorizes a motion to dismiss to contest public use/purpose and requires it be tried contradictorily.
  • The statutory structure makes a public-use challenge a distinct, expedited adjudication, and failure to bring it timely waives defenses other than compensation (La. R.S. 19:147(B)).

Practically, this confirms that “public purpose” disputes in quick-take cases are intended to be resolved by an early evidentiary contest—not deferred into valuation-only litigation.

(B) The constitutional holding: “public port” status is not satisfied by public ownership plus a private-exclusive lease

The Court’s constitutional analysis turned on the post-2006 text of La. Const. art. I, §4, especially:

  • §4(B)(1): takings only for public purposes, and not (with limited exceptions) for predominant use by a private entity or transfer of ownership to a private entity;
  • §4(B)(2): “public purpose” is limited to enumerated categories, including “[c]ontinuous public ownership of property dedicated to… [p]ublic ports… to facilitate the transport of goods or persons…”;
  • §4(B)(3): economic development, tax revenue, and incidental public benefits are excluded from the “public purpose” calculus.

From this structure, the Court reasoned that the constitutional “public port” category is not a blanket endorsement of any taking by a port authority. Rather, it demands that the taking be for property dedicated to use as a public port. On the Court’s characterization of the record, Plaquemines Port was taking Nguyen’s land solely to lease it to Venture Global for Venture Global’s own project and goods—making the project’s “port” function effectively private-exclusive.

(C) Article VI, section 21 did not salvage the taking

Plaquemines Port argued that Article VI, section 21 supplies an “exception” allowing acquisition and leasing of property (including via expropriation) to induce industrial enterprises and facilitate port operations. The Court rejected that pathway because, in its view, Plaquemines Port failed the threshold requirement: the taking was not for a constitutionally defined public purpose under Article I, §4 as limited after 2006. Without a public purpose, the Court deemed the “predominant private use” exception framework inapplicable.

(D) Economic-development justifications were constitutionally irrelevant

Plaquemines Port argued the project aligned with “economic growth, job creation, energy security, and environmental stewardship.” The Court treated these as precisely the types of considerations barred by La. Const. art. I, §4(B)(3). The opinion thus reinforces that Louisiana’s constitution deliberately removes familiar policy arguments from the takings analysis; the inquiry is not whether the project is beneficial, but whether it is a constitutionally enumerated public purpose.

3.3 Impact

(A) A sharper boundary for port expropriations tied to private megaprojects

The decision draws a firm line: a port authority cannot condemn property merely to assemble land for a private industrial user, even when the resulting facilities relate to maritime commerce, if the property’s dedicated use is essentially for the private party’s exclusive operations. This will likely require ports to demonstrate a stronger nexus to public port functions (e.g., shared access, general public/shipper service, integrated port operations) rather than a landlord-tenant structure built around a single private beneficiary.

(B) Litigation dynamics in quick-take cases

By reaffirming the La. R.S. 19:147 motion-to-dismiss mechanism and its contradictory-hearing design, the opinion incentivizes early, front-loaded litigation over public purpose. Expropriating authorities should expect—and prepare for—early evidentiary challenges focused on the real-world use and operational control of the property.

(C) Post-2006 constitutional text remains a meaningful constraint

The ruling signals that Louisiana courts will enforce the 2006 amendments as substantive limits, not formalities satisfied by public ownership titles. It also reduces the likelihood that “public-private partnership” labeling or lease structuring can substitute for the constitution’s requirement of a genuinely public-dedicated use.

4. Complex Concepts Simplified

  • Expropriation / eminent domain: the government’s power to take private property, but only for a constitutionally valid public purpose/use and with just compensation.
  • Quick-take (La. R.S. 19:141 et seq.): a procedure allowing certain entities (including ports) to obtain title/possession early by depositing estimated compensation, while specific defenses (like “not a public use”) must be raised quickly.
  • Motion to dismiss under La. R.S. 19:147: the statutorily prescribed method for a landowner to challenge whether the taking is for a public use/purpose in a quick-take case; it is heard contradictorily (both sides present).
  • Public purpose (Louisiana, post-2006): not a broad “public benefit” test; it is limited to enumerated categories in the constitution and excludes economic development/tax revenue as justifications.
  • “Public ports” as a public purpose: the constitution recognizes ports as public purposes only where there is continuous public ownership of property dedicated to port use facilitating transport in commerce—meaning the property must function as a public port facility, not merely be owned by a port while used privately.
  • Predominant private use: taking property mainly so a private entity can use it is constitutionally disfavored; Louisiana’s post-2006 framework is designed to prevent “take from A to give to B” economic-development condemnations.

5. Conclusion

establishes (and clarifies) a practical rule under Louisiana’s post-2006 takings regime: a port authority may not expropriate private property solely to lease it to a private company for that company’s exclusive development and use, because such a taking is not a constitutionally defined public purpose under La. Const. art. I, §4.

The decision reinforces two broader takeaways: (1) Louisiana’s constitution meaningfully limits eminent domain beyond federal Kelo-style “public benefit” reasoning, and (2) in quick-take proceedings, the legislature has provided landowners an expedited, evidentiary path—via La. R.S. 19:147—to test whether the asserted public purpose is real, lawful, and constitutionally sufficient.
