NOT PUBLISHED PURSUANT TO C.A.R. 35(e) Announced April 9, 2026

Artemis Law, LLC, Leigh Horton, Denver, Colorado, for Plaintiff-Appellant

The Burnham Law Firm, P.C., Brian D. Teed, Centennial, Colorado, for Defendant-Appellee ¶1 Plaintiff, Thomas Wierimaa, appeals the trial court’s judgment

entered on a jury verdict finding that he assaulted defendant, Anna

Cheng, his then-wife, and awarding her $468,750 in damages. We

affirm in part and reverse in part and remand the case to the trial

court with directions.

I. Background

¶2 Cheng has two children from a previous marriage, S.W. and

H.C. She and Wierimaa married in 2017 and had one daughter,

B.W., in 2019. During their relationship, Cheng was mostly

unemployed; Wierimaa worked full-time and attended law school.

Wierimaa filed for legal separation in September 2021, and the

couple finalized their divorce in January 2023. During the divorce

proceeding, Cheng told people that Wierimaa was abusive to her

and the children.

¶3 Wierimaa filed the underlying lawsuit on February 10, 2023.

He brought claims of (1) abuse of process; (2) defamation (child

abuse); (3) defamation (domestic violence); (4) intentional infliction

of emotional distress (public smear campaign); (5) intentional

infliction of emotional distress (kidnapping minor child); and

1 (6) tortious interference with parental relations (September 2022

kidnapping of minor child).1

¶4 Cheng denied the allegations and filed counterclaims for

(1) abuse of process; (2) defamation per se; (3) extreme and

outrageous conduct (emotional distress); (4) assault; and

(5) battery. Cheng supported her counterclaims by alleging the

following incidents:

• In February 2016, while on vacation in Cancun, Mexico,

Wierimaa grabbed Cheng by the wrist, threw her onto a bed,

and caused her to fall on a hand mirror, which left her with

bruises and a back injury (the Cancun incident).

• On February 4, 2018, Wierimaa disciplined H.C. while

watching the Super Bowl. When Cheng protested, Wierimaa

yelled at her and told her to leave the home. She and the

children left (the Super Bowl incident).

1 Wierimaa later amended his complaint and added claims of

(7) abuse of process (2023 statements to child protective services); (8) malicious prosecution (2023 statements to child protective services); (9) defamation (false allegations of child abuse after February 14, 2023); (10) defamation (false allegations of domestic abuse after February 14, 2023); and (11) exemplary damages.

2 • On September 8, 2019, Wierimaa yelled at Cheng. She tried to

leave the home with all her children, but Wierimaa would not

let her take B.W. She left with S.W. and H.C. (the September

8 incident).

• On March 10, 2021, Wierimaa became angry because Cheng

didn’t know he was leaving on a business trip (the March 10

incident).

• On September 16, 2021, Wierimaa told Cheng that he had

filed for legal separation and called her a “child,” “immature,”

and a “cunt” (the September 16 incident).

• On March 11, 2022, Wierimaa threatened that he would

litigate against Cheng until B.W. turned eighteen (the March

11 incident).

• On July 5, 2022, police came to Cheng’s home to perform a

welfare check. During the visit, Cheng contacted Wierimaa

and put him on speaker phone. The officers noted that

Wierimaa sounded controlling and threatening (the July 5

3 ¶5 Wierimaa and Cheng filed separate special motions to dismiss

under Colorado’s anti-SLAPP2 law, which the court denied.

Wierimaa filed a second motion to dismiss, which the trial court

partially granted with respect to Cheng’s assault claim concerning

the Cancun incident (because it was outside the statute of

limitations) and allowed her to amend her counterclaims, which she

did. She removed the Cancun incident and added more details

about the September 8 incident. Specifically, she indicated that

when she was getting the children ready that morning, Wierimaa

verbally berated her and the children. Cheng went to B.W.’s room

to pick her up from her crib and console her after she started

crying. B.W.’s crib was in the bedroom’s walk-in closet. Wierimaa

followed Cheng into the bedroom, continued to yell at her, used his

body to block Cheng in the closet, and “physically snatched” B.W.

out of Cheng’s arms. Cheng left the closet, grabbed S.W. and H.C.

along with their things for the day, and then left with the two older

children. During this time, Wierimaa continued to berate her,

Hinds v. Foreman, 2026 CO 9, ¶ 1.

4 saying she was a “horrible mother,” a “mistake,” and a “horrible

person.”

¶6 Wierimaa moved for summary judgment at the conclusion of

discovery, arguing that (1) no battery occurred because there was

no physical contact during the alleged events; (2) no assault

occurred because Cheng was not placed in apprehension of any

immediate physical contact; (3) Cheng could not prove any abuse of

process; (4) Cheng’s defamation per se claims were barred by the

absolute litigation privilege and the doctrine of substantial truth;

and (5) Cheng could not prove or establish extreme and outrageous

conduct. The court granted the motion with respect to Cheng’s

counterclaims of (1) abuse of process; (2) defamation; and

(3) extreme and outrageous conduct, but it denied summary

judgment with respect to Cheng’s assault and battery claims arising

from the September 8 incident.

¶7 Wierimaa filed two motions in limine. The first was to exclude

evidence of Cheng’s dismissed counterclaims and to limit evidence

and testimony on Cheng’s assault and battery counterclaims to the

events that occurred on September 8, 2019. The second was to

exclude evidence of a phone call Wierimaa had with a health care

5 insurance agent in May 2024 to illustrate his “aggressive

character.” During the pretrial conference, the court granted

Wierimaa’s motions because the challenged testimony would be

unduly prejudicial. However, the court noted that the evidence

could be admitted at trial if it became relevant.

¶8 At trial, Cheng testified that she and Wierimaa had the

following acrimonious arguments during their relationship:

• During a family trip to India in 2016, Cheng asked Wierimaa

to get off his phone during breakfast. An argument ensued,

Wierimaa began yelling at Cheng, and Wierimaa went to pack

his bags to return home to Denver. Cheng and her children

didn’t have a flight home, so Cheng begged Wierimaa to return

to the hotel room, which he eventually did (the India incident).

• During a family trip to Peru in 2016, Cheng asked Wierimaa to

take a picture of her and the children at the base of Machu

Picchu, to which Wierimaa responded, “No, you have enough
