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.

Court Examines Requirements of Financing Provision in Purchase Agreement for  Residential Property

Purchase agreements for residential property routinely include financing provisions that require the buyer to show that he has applied for a loan. The Louisiana Fourth Circuit Court of Appeals recently analyzed such a provision in Abdelqader v. Ramos. The plaintiff in Abdelqader entered into a purchase agreement with the defendant for an unimproved lot on which the plaintiff planned to build his home.

The financing provision in the purchase agreement required the buyer to provide the seller with (1) written documentation; (2) from a lender; (3) that a loan application has been made; and (4) that Buyer authorized lender to proceed with the loan approval process. The provision also required that this documentation be provided to the seller “within 3 calendar days after” the date of Agreement.

After the parties executed the purchase agreement, various disputes led the seller to terminate the agreement and re-list the property for sale. The plaintiff sued for stipulated damages and attorney’s fees, which were allowed under the contract if either party breached the purchase agreement.

The buyer introduced evidence that his agent sent the seller’s broker a USDA pre-approval letter and certificate of eligibility for financing under a USDA Rural Development Program. These documents were sent to the seller’s agent before the parties executed the purchasing agreement. Generally, such pre-approval letters show the buyer appears qualified for a loan in the amount of the purchase. They do not confirm a loan was applied for or approved by the lender for the property to be purchased.

The seller argued that the pre-approval letter furnished by the buyer before the parties entered into the purchase agreement was not an actual loan application and did not verify that a loan application for the purchase had been made. The seller also argued that the buyer did not comply with the terms of the financing provision because he did not provide the subject documents within the three-day window after the purchase agreement was signed. The court rejected these arguments. The Court found the agreement did not require the buyer to produce his loan application to the seller or that the loan application be dated within three days of the Agreement. The buyer’s lender produced the pre-approval letter and the certificate of eligibility in response to the buyer’s application for financing and pursuant to the buyer’s instruction to proceed with the loan process. Though its ruling may be limited to the facts of this case, the Court found that the buyer complied with the terms of the financing agreement.

It appears the court viewed the seller’s claim that the seller did not comply with the financing provision of the purchasing agreement as after the fact justification for the seller unilaterally terminating the purchase agreement for some unrelated dispute. The Court found that the seller breached the purchase agreement and awarded the buyer stipulated damages of 10% of the contract price and attorney’s fees. This ruling also serves as a reminder that purchase agreements for residential properties are contracts, and breaches of these contracts can have consequences if terminated on a whim.

Keeping Testimony of Future Medical Expenses “Out of the Gate”

Ina recent case involving Keogh Cox attorneys, the Eastern District of Louisiana in MichaelBrander, Jr. v. State Farm Mutual Auto. Ins. Co., Civ. A. No. 18-982(Feb. 14, 2019), 2019 WL 636423 barred testimony of substantial projectedmedical expenses because it was not based on a reliable methodology. Thisruling stands to impact many other cases where plaintiffs seek to usefar-reaching projections of a life-long need for radiofrequency ablations("RFAs") or other pain-management modalities to "board" sixand even seven-figure numbers for future medical expenses.

InDaubert v. Merrill Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), theUnited States Supreme Court recognized the trial judge as the “gatekeeper” of expertopinion testimony and held that only reliable and relevant expert opinions maybe admitted. The reliability requirement serves to keep expert opinions“outside the gate” when they constitute unsupported speculation or meresubjective belief; only scientifically valid expert opinions are allowedinside. To ascertain whether an expert opinion is scientifically valid, Daubertinstructs the trial court to consider:

∙ whether theexpert’s theory can or has been tested;

∙ whether it hasbeen subject to peer review and publication;

∙ the known orpotential rate of error when applying the theory;

∙ applicablestandards and controls; and,

∙ the degree towhich the theory has been generally accepted in the scientific community.

InBrander, the plaintiff advanced medical testimony that he would needRFAs every year of his expected lifetime, a period of 36 years. The courtdisallowed the testimony, noting that the plaintiff’s physicians had less thanten years personal experience in administering RFAs to patients, the medicalliterature only considered the effectiveness of RFAs over a span of seven toten years, and there was no showing that the 36-year treatment plan was ingeneral acceptance by the medical community. According to the court, theexpert opinions offered by plaintiff failed Daubert “on all points.” Asa result, the plaintiff was permitted to introduce testimony of future RFAs foronly a seven-year period.

The reasoning of Brander may be equally applicable to projections of lifetime treatment involving other medical procedures, such as medial branch blocks, Botox injections, or spinal cord stimulators, for which the long-term efficacy has not been firmly established in the medical literature. Opinions unsupported by personal treatment experience and peer-reviewed medical studies are not scientifically valid and are properly halted “at the gate.”

Hurricane Ida: Governor Extends Legal Deadlines

We previously reported that the Louisiana Supreme Court issued Orders suspending prescriptive, peremptive and abandonment periods for thirty days in the wake of Hurricane Ida. Governor John Bel Edwards has now issued a Proclamation. In addition to other actions, the Proclamation provides that legal deadlines applicable to “legal proceedings in all courts, administrative agencies, and boards” are suspended until September 24, 2021.

The Proclamation also authorizes hotels and motels to cancel reservations which would result in the displacement or eviction of first responders, health care workers, or anyone performing disaster-related work.
