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

(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.

• 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 incident).

¶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,

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

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 F---ing photos.” Wierimaa left Cheng and S.W. and took H.C.

(who was then one year old) to the top of Machu Picchu.
