FROM: CLERK OF SUPREME COURT OF LOUISIANA

The Opinions handed down on the 18th day of December, 2025 are as follows:

BY Weimer, C.J.:

2025-C-00169 NGOC TROUNG VS. MARCUS DEWAYNE SANDERS AND OLD AMERICAN INDEMNITY COMPANY (Parish of Caddo)

AFFIRMED IN PART; REVERSED IN PART. SEE OPINION.

Hughes, J., dissents in part and would affirm the court of appeal. SUPREME COURT OF LOUISIANA

No. 2025-C-00169

NGOC TROUNG

VS.

MARCUS DEWAYNE SANDERS AND OLD AMERICAN INDEMNITY, COMPANY

On Writ of Certiorari to the Court of Appeal, Second Circuit, Parish of Caddo

WEIMER, Chief Justice.

The threshold issue in this case is whether a tortfeasor has a legal right to

deduct for betterment1 in connection with a tort victim’s claim for property damages

to a vehicle and, if not, whether the tortfeasor is liable for penalties for asserting such

a right. Because the law contemplates full indemnification of a third-party tort

victim, the court of appeal’s finding that the tortfeasor is not entitled to reduce the tort

victim’s property damage recovery for betterment in this matter is affirmed.

Nonetheless, because this matter does not involve a misrepresentation of pertinent

facts and presents a legal issue of first impression, the award of penalties is not

warranted and was, therefore, reversed.

1 Betterment is “[a]n improvement that increases the value of real property; esp., an enhancement in the nature of an alteration or addition that goes beyond repair or restoration to a former condition.” BLACK’S LAW DICTIONARY, p. 153 (12th ed. 2024). FACTS AND PROCEDURAL HISTORY

On January 21, 2023, Marcus Sanders rear-ended the 2019 Honda CR-V being

driven by Ngoc Troung. Mr. Sanders’ vehicle was insured by Old American

Indemnity Company (Insurer). As a result of the collision, Mr. Troung’s vehicle was

inoperable due to the damage to the exhaust system, components of the drive

assembly, and a tire.2 On February 6, 2023, the matter was assigned by Insurer to

appraiser Chad Rogers for review. He prepared an initial estimate that same day for

repairs to the rear bumper and the lift gate totaling $3,008.02, which was promptly

paid to Mr. Troung by check dated February 9, 2023. At Mr. Troung’s direction, his

vehicle was delivered to Roundtree/Mercedes-Benz of Shreveport Collision Center

for repair. On February 15, 2023, the repair shop requested supplementation of the

initial estimate to include replacement of a tire and repairs to the quarter panel, rear

body and floor, and exhaust system. Mr. Rogers, Insurer’s appraiser, completed the

supplement on February 16, 2023, which brought the estimated repair cost to

$6,421.08. The “Supplement of Record 1” reflects a $313.79 adjustment for

“[b]etterment applied for prior tread wear (5/32 tread remaining)” ($131.95) and

“[b]etterment applied for prior wear on mechanical part”–muffler and pipe ($130.38)

and rear muffler ($51.46). In light of the adjustment, the net repair cost was

$6,107.29, an increase of $3,099.27, which was paid directly to the repair shop by

check dated February 17, 2023. Additional requests were received from the repair

shop resulting in three more supplementations of the initial estimate by Mr. Rogers,

each reflecting the $313.79 betterment deduction with checks being issued on

February 23, 2023, for $301.87, March 3, 2023 for $127.16, and March 14, 2023 for

$259.37. In light of the betterment deduction first noted in the February 16, 2023

2 The accident pushed the muffler into the tire, melting the tire’s interior wall.

2 supplement, Insurer’s payments for the $7,109.48 damages to Mr. Troung’s car

totaled $6,795.69. Mr. Troung’s vehicle was in the shop for replacement of the

muffler, exhaust system pipes, front-wheel-drive components, and a tire through

March 16, 2023, or roughly one and a half months. When Mr. Troung went to

retrieve his vehicle, the repair shop refused to release it because of the $313.79

unpaid balance attributed to the betterment deduction asserted by Insurer. To enable

him to get his vehicle, Mr. Troung’s attorney paid the balance.

Despite demands, Insurer refused to provide reimbursement, resulting in Mr.

Troung filing suit. In his petition, Mr. Troung alleged that “Louisiana law does not

provide for ‘betterment’ and does not permit a [tortfeasor’s] liability insurer to

withhold any amounts from the full amount of money required to fix the damages

caused to a tort victim’s vehicle.” Mr. Troung sought penalties based on allegations

that Insurer’s “refusal to pay the full amount of the required repairs is baseless and

thus is also arbitrary and capricious and without probable cause.”

On July 6, 2023, Insurer issued a check for $667.83, double the amount of the

betterment deduction, to Mr. Troung and his attorney while maintaining the right to

a betterment deduction. In their pretrial order, the parties stipulated to all pertinent

facts and to the resolution of all issues of liability and damages. The only issues that

remained for trial were (1) whether Louisiana law provides for a betterment deduction

within the context of a third-party property/tort damage claim, (2) whether Insurer’s

assertion of a betterment deduction constituted a misrepresentation within the

meaning of La. R.S. 22:1973(B)(1), and (3) whether Insurer owed the penalties under

La. R.S. 22:1973(C). Pursuant to the agreement of the parties, the matter was

submitted to the trial court without live testimony, but with the presentation of

3 evidence (including the deposition testimony of Insurer’s appraiser Mr. Rogers and

his supervisor, Wesley Staley) and oral arguments.

According to Mr. Rogers, “betterment,” which “is the process of applying a

deduction to the cost of a component, due to the fact that it is replacing a part or

component [part] on a vehicle with a newer, unused part,” is a common industry

standard for third-party claims. For safety reasons, the tire and component of the

exhaust system could not be replaced with comparable used parts. Mr. Rogers

explained how he arrived at the deduction amounts for the wear and tear of the two

items in question:

For the tire [Insurer] took betterment of $131.95. That is a 50- percent betterment on the cost of the tire only, including tax, and we arrived at that from the tire tread depth gauge showing 5/32 of an inch tread remaining. Standard tread depth on a passenger vehicle tire is 11/32 when brand-new, so this was approximately half of the tread remaining on the tire, so we applied the 50-percent betterment.

....

[F]or the intermediate pipe, which is referred to on here as the muffler and pipe, we took $130.38. That is a betterment of 23 percent. For the rear muffler itself we took $51.46, which again is 23 percent. We arrived at that based on the calculation of the mileage on the vehicle at the time of loss versus a[n] expected life expectancy of 200,000 miles for wearable mechanical components.

Mr. Staley confirmed that betterment deductions for third-party claims are a

common practice in the insurance industry.

The trial court found that betterment as that term is used to establish a credit

against the amount due by the tortfeasor to the tort victim in connection with third-

party automobile property damage claim is allowed, as it is not expressly prohibited

by Louisiana law, the jurisprudence, or regulation.
