Opinion issued January 15, 2026

In The

Court of Appeals For The

First District of Texas ———————————— NO. 01-24-00087-CV ——————————— LI LI, Appellant V. TGS-NOPEC GEOPHYSICAL COMPANY, Appellee

On Appeal from the 190th District Court Harris County, Texas Trial Court Case No. 2019-84389

O P I N I O N

This appeal arises out of a lawsuit in which Li alleged sex discrimination and

retaliation against her former employer, TGS-NOPEC Geophysical Company. A

jury rejected Li’s claims, finding she did not prove discrimination or retaliation. Li argues that the trial court reversibly erred in refusing to offer two

permissive-pretext jury instructions that she requested. It did not.

Trial courts have considerable discretion as to jury instructions. For Li to

prevail, Texas law is clear: When a trial court refuses to submit a requested

instruction that is otherwise proper, we consider on appeal whether the requested

instruction was reasonably necessary for the jury to render a proper verdict.

Here, assuming for these purposes that the instructions Li requested were

proper, they were not reasonably necessary to enable the jury to render a proper

verdict—much like in our sister court’s decision in Johnson v. National Oilwell

Varco, LP, which addressed a closely analogous situation. 574 S.W.3d 1, 12 (Tex.

App.—Houston [14th Dist.] 2018, no pet.). We reject Li’s jury instruction argument.

Beyond this, Li also argues that there was factually insufficient evidence to

support the jury’s findings against her. We again disagree. The jury is the judge of

credibility, and the findings were not so against the great weight and preponderance

of the evidence as to be manifestly unjust, shock the conscience, or clearly

demonstrate bias.

We affirm the trial court’s take-nothing judgment as to Li’s claims.

2 BACKGROUND

TGS-NOPEC is in the business of providing geoscience data to oil and gas

companies. TGS-NOPEC terminated Li after she had been employed as a

geophysical software developer with the company for about three and a half years.

Afterward, Li sued TGS-NOPEC. Li alleged that TGS-NOPEC discriminated

against her because she is a woman, including by advancing and paying her less than

comparable male coworkers. Li additionally asserted that TGS-NOPEC retaliated

against her by terminating her employment after she complained about the

company’s discrimination. She brought claims under Texas statutory law (not

federal law). See TEX. LAB. CODE §§ 21.051, 21.055 (“[E]mployer commits an

unlawful employment practice if because of . . . sex . . . the employer . . . discharges”

employee or retaliates against employee for filing complaint).

The parties tried the suit to a jury over the course of five days. The jury heard

from four witnesses. These included Li and three TGS-NOPEC employees: Li’s

direct supervisor, Sampath Gajawada; Gajawada’s supervisor, Bin Wang; and a

member of the company’s Human Resources department, Heather Barker. In

addition, the parties introduced approximately 900 pages of documents as exhibits.

Li’s theory of the case was that she received less favorable treatment than

male coworkers, complained about it, and was eventually terminated in retaliation.

3 TGS-NOPEC denied either discriminating or retaliating against Li. It attributed her

termination to poor job performance.

At issue here, before the case was submitted to the jury, Li asked the trial court

to include two permissive-pretext instructions in the jury charge.

First, as part of the jury question inquiring whether Li’s sex (female) was a

motivating factor in TGS-NOPEC’s decision to terminate her employment, Li

requested that the trial court include the following instruction:

If you do not believe the reason TGS has given for discharging Li Li, you may, but are not required to, infer that TGS was motivated by Li Li’s sex (gender: female).

Second, as part of the jury question inquiring whether TGS-NOPEC

terminated Li’s employment because she complained about sex discrimination, Li

requested that the trial court include the following instruction:

If you do not believe the reason TGS has given for its decision to discharge Li Li, you may, but are not required to, infer that TGS would not have discharged Li Li but for discrimination complaints.

Without stating its reasons, the trial court refused the instructions.

The jury returned a defense verdict. It found that Li’s sex was not a motivating

factor in the company’s decision to terminate her employment. It also found that

TGS-NOPEC did not fire Li because she complained of sex discrimination.

4 Based on the verdict, the trial court rendered a take-nothing judgment.1 Li now

appeals.

DISCUSSION

I. We reject Li’s jury instruction argument: Her requested instructions were not reasonably necessary to enable the jury to render a proper verdict.

A. A trial court has considerable discretion in whether to submit proposed jury instructions.

“A trial court has broad discretion in constructing the charge, so long as it is

legally correct.” Emerson Elec. Co. v. Johnson, 627 S.W.3d 197, 208 (Tex. 2021);

see also Gunn v. McCoy, 554 S.W.3d 645, 675 (Tex. 2018). Similarly, a “trial court

has considerable discretion in determining which jury instructions are necessary and

proper in a particular case.” Johnson, 574 S.W.3d at 10.

An instruction is proper if it assists the jury, accurately states the law, and

finds support in the pleadings and evidence. Gunn, 554 S.W.3d at 676. But a

requested instruction does not become mandatory (and its refusal is not grounds for

reversal) merely because it is proper. Id. (“[T]he decision to refuse a requested

instruction remains within the trial court’s discretion, and a determination that a

requested instruction was proper does not render it mandatory.”). A jury also should

not be burdened with surplus instructions, even those that accurately state the law.

1 Li moved for judgment notwithstanding the verdict and for a new trial. The trial court denied both of Li’s motions.

5 Arocha v. State Farm Mut. Auto. Ins. Co., 203 S.W.3d 443, 445 (Tex. App.—

Houston [14th Dist.] 2006, no pet.).

We reverse based on asserted charge error only when the error (if there is

error) “probably caused the rendition of an improper judgment or prevented the

petitioner from properly presenting the case to the appellate courts.” Gunn, 554

S.W.3d at 675.

In a civil case like this one, Texas’s test is clear: “[W]hen a trial court refuses

to submit a requested instruction that is otherwise proper, the question on appeal is

whether the request was reasonably necessary to enable the jury to render a proper

verdict.” Emerson, 627 S.W.3d at 209 (quoting Gunn, 554 S.W.3d at 675); see also

Johnson, 574 S.W.3d at 10 (“When a trial court refuses to submit a requested

instruction, the question on appeal is whether the request was reasonably necessary

to enable the jury to render a proper verdict.” (citing TEX. R. CIV. P. 277 & 278));
