Supreme Court Clarifies Requirements of Unjust Enrichment Claim

Published on: August 12, 2025

Under Louisiana law, unjust enrichment is a cause of action that is based in equity and provides that no one should be enriched at the expense of another. The elements of an unjust enrichment claim are: (1) an enrichment; (2) an impoverishment; (3) a connection between the enrichment and the impoverishment; (4) an absence of justification or cause for the enrichment and impoverishment; and (5) no other available remedy at law. The Supreme Court recently addressed the fourth element regarding the absence of justification for the enrichment.

In H & O Invs., LLC v. Par. of Jefferson Through Sheng, a grass cutting contractor entered into a contract with the Parish for grass cutting in certain areas. The Parish separately contracted with a second contractor for weed control of the same areas. During the contract period, the grass cutting contractor notified the Parish that there was unanticipated weed growth and suggested that the weed control contractor was not properly applying the herbicide. The grass cutting contractor alleged that its work became more expensive because of the weed control contractor’s failure to perform its contractual obligation.

The grass cutting contractor sued the Parish alleging unjust enrichment. The Parish filed an exception of no cause of action, claiming that there was no claim for unjust enrichment because a contract existed between the parties. The Fifth Circuit disagreed and held that the contractor could bring a claim for unjust enrichment because there was no contractual claim between the contractor and the Parish, as both parties fulfilled their contract obligations.

The Supreme Court reversed, noting that a claim for unjust enrichment requires a showing that there was an “absence of justification or cause for the enrichment.” The Supreme Court held that when a contract exists between the parties, it serves as the law between them, and that contract is the legal cause or justification for the enrichment. Therefore, the contract between the contractor and the Parish was in fact the justification for the enrichment such that it could not be “unjust.” The Supreme Court dismissed the contractor’s suit against the Parish.

Louisiana Appeal Court Finds Nonparty “Nonresident” Industrial Site Owner Is Subject to Louisiana’s Subpoena Power

Can a nonresident corporation, who is not a party to a pending action, be compelled to respond to discovery in Louisiana? The Louisiana Fifth Circuit says YES. See Molaison v Cust-O-Fab Specialty Services, LLC, a case where Keogh Cox successfully handled the appeal.

The Molaison case involved an industrial accident claim where catastrophic injuries were alleged. In this context, the appellate court found that a non-resident company has sufficient presence in Louisiana to subject it to the court’s subpoena power. However, the trial court must first assess the scope of discovery to ensure it is calculated to lead to discoverable evidence and is not too onerous.

In Molaison, the owner of an industrial plant who employed the plaintiff claimed that its nonresident status prevented the parties from requiring it to respond to discovery by deposition or otherwise. The plant owner cited a Louisiana Supreme Court case that held personal jurisdiction, without more, did not subject a nonparty, out-of-state defendant to submit to discovery in this state.

But, in this case, the nonparty maintained a facility in Louisiana and employed the plaintiff. As a consequence, the Molaison court found that the Louisiana “discovery rules control” and “the trial court did not err in finding that (the company) was subject to the subpoena power of a Louisiana court.”

The contractor established it issued the subpoena to obtain evidence from the chemical plant owner that was relevant to the allocation of fault under Louisiana’s pure comparative fault tort system. Therefore, the appeal court reasoned that the nonresident plant owner was subject to the subpoena, “even if (the company) is not obligated to pay in tort by operation of workers compensation immunity.”

Of note, the court also held that the review of a discovery order that finds a nonresident company subject to the subpoena power is a final appealable judgment, as opposed to an interlocutory order subject the discretionary review on supervisory writ.

Nursing Home Liability: Big Brother is Watching Granny?

As an integral theme to his best-selling novel Nineteen Eighty-Four, George Orwell once used the slogan: “Big Brother is Watching You.” This slogan embodied the idea that a person’s actions and intentions are being monitored by the government as a means of controlling and suppressing the will of the populace.

Although not as extreme as Orwell’s dystopian novel, Louisiana families will now be able to install video monitoring systems in their loved ones’ nursing home rooms pursuant to Act 596 of the 2018 Regular Session of the Louisiana Legislature. According to the “Nursing Home Virtual Visitation Act,” nursing homes can not prohibit the cameras or retaliate against residents who want to install them. The video systems will monitor residents who often cannot speak for themselves.

However, several requirements must be met to abide by the Act:

  1. The resident, or family if the resident lacks capacity, must provide notice of installation to the facility;
  2. Visual recordings must include date and time;
  3. The device must be stationary and fixed, not oscillating;
  4. Residents must pay all costs for installation, upkeep, and removal;
  5. Written consent is required from all roommates;
  6. Room changes are required if a roommate does not consent;
  7. Residents and applicants cannot be retaliated against for authorizing devices; and
  8. Signage must be installed at the front door of the facility (at the facility’s cost) and at the resident’s room (at the resident’s cost) advising of surveillance in the rooms.

Furthermore, nursing homes must provide forms to nursing home residents, or their legal guardians, outlining the ways the cameras can be installed. Under the Act, surveillance should be addressed at admission as a resident right. To promote compliance, the Act prohibits the use of any recordings in litigation when the device was installed or used without the nursing home’s knowledge or used without adherence to the required forms. Additionally, compliance with the Act is a complete defense against lawsuits brought purely because monitoring devices are in use.

Nursing facilities and the families of residents and patients should take care to comply with all of the requirements in the act to ensure that the video footage is actually admissible and that the facilities are not opening themselves to privacy lawsuits from other residents. “Big Brother” might not be watching, but the increase in affordable, high quality, surveillance cameras, coupled with the Virtual Visitation Act, means nursing facilities should anticipate that someone could be watching very soon.

UM Waiver Completed by Insured’s Assistant Found Invalid

Uninsured/underinsured motorist coverage (“UM coverage”) is included in all automobile liability policies by Louisiana law unless the insured “rejects [UM] coverage, selects lower limits, or selects economic only coverage.” What constitutes an adequate rejection of UM coverage has been the crux of countless lawsuits across the state. Recently, in Havard v. Jeanlouis, et al, 2021-C-00810 (La. 6/29/22), the Louisiana Supreme Court examined the validity of a corporate representative’s signature in the context of execution of a UM waiver form. Louisiana courts have found that without a valid signature, UM coverage generally may not be waived.

The Havard court recognized that a corporation cannot “sign” its own name, and that an authorized representative must act on its behalf. Under the facts of this case, an administrative assistant attempted to execute a UM waiver form at the corporate representative’s direction with a stamp of the representative’s signature. The plaintiff argued that the use of the stamp did not meet the requirements for proper execution of the UM waiver form at issue.

Considering these facts, the court noted that Louisiana law of mandate provides that “when the law prescribes a certain form for an act, a mandate authorizing the act must be in that form.” The court continued: “Accordingly, where one individual signs a UM form on behalf of another individual and authority is not conferred by law, our Civil Code requires this authority be in writing.”

While the corporate representative in Havard verbally instructed his administrative assistant to complete the waiver with his signature stamp, no written mandate existed between the representative and the assistant to confirm this authority. Absent the written mandate, the court disregarded the express intention of the corporate representative and held the form invalid.

The court recognized the impracticality of its holding. However, it also commented “Concerns over the practical impact within the insurance industry in scrutinizing stamped signed UM forms are unavailing. Inconvenience is not absurdity. The insurer has the authority, opportunity, and responsibility to assure the UM form is completed properly. … Practical considerations regarding increased due diligence requirements are matters of policy best directed to the legislature.”

Cases involving UM waiver forms are fact-sensitive. Havard involved unique facts where the company’s authorized agent did not sign the UM waiver form personally. While Havard may be limited to its facts, it reminds that proper execution of a UM waiver form is necessary for UM coverage to be properly waived.
