Filed: __________________________________________ Clerk

2 Justice Laurie McKinnon delivered the Opinion of the Court.

¶1 Kevin R. Frost (Kevin) appeals from the August 2, 2024 Order of the Twenty-First

Judicial District Court, Ravalli County, granting Sherri Frost’s (Sherri) motion for a new

trial. The District Court held that the jury’s award of $20,000 in damages was not

supported by substantial evidence because Sherri had established at least $20,000 in past

medical expenses alone, as well as proved that she was entitled to some compensation

related to at least one other category of damages. Sherri cross-appeals the District Court’s

order granting Frost Ranching Corporation’s (the Ranch) Rule 50 motion for judgment as

a matter of law. Sherri maintains the court erred in concluding the Ranch could not ratify

Kevin’s conduct absent a “successful benefit” to the Ranch.

¶2 Kevin presents the following issue for review:

1. Whether the District Court correctly held there was insufficient evidence to support the jury’s award of damages.

Sherri raises the following issue on cross-appeal:

2. Whether the District Court correctly held that the Ranch could not ratify Kevin’s conduct absent a “successful benefit” to the Ranch.

FACTUAL AND PROCEDURAL BACKGROUND

¶3 The origins of this matter date back to February 2016, when Kevin kidnapped his

estranged wife, Sherri. At the time, the two parties were engaged in a contentious divorce,

and they no longer resided together. On the morning of February 9, 2016, Kevin drove to

the house of Sherri’s new boyfriend, Brian Moore. He placed a garbage can in the driveway

so Sherri would have to stop to get out to move it. When she did, Kevin seized her and

forced his way into her vehicle. Kevin then took her to where he had parked a GMC Yukon 3 that he purchased two weeks previously. Kevin never told anyone in his family that he had

purchased the Yukon; the Yukon was not registered; and Kevin kept it parked in downtown

Hamilton far from his own property. Once the Yukon was retrieved, Kevin took Sherri to

a barn owned by a longtime associate of the Frost family, Dean Allen. Allen leased the

land from the Frost Ranch and paid Kevin to take care of his property any time he was out

of state. After holding Sherri for roughly six hours, during which Kevin forced her to

become severely intoxicated, he delivered her to the emergency room and turned himself

in to the Ravalli County Sheriff’s Office. Sherri’s Blood Alcohol Content was measured

at 0.140. Kevin plead guilty to partner family member assault and kidnapping, and served

a prison sentence from June 9, 2017, to September 16, 2020. Additionally, Kevin is subject

to a restraining order that prevents him from contacting Sherri.

¶4 On February 2, 2018, Sherri filed her initial complaint seeking damages and

demanding a jury trial. In addition to Kevin, the complaint named as defendants Margot

and Dean Allen, who own the property where Kevin took Sherri; the Frost Ranching

Corporation, which owns and operates Kevin’s family ranch; the Frost Limited Partnership,

which owns the land constituting the Ranch; and multiple insurance companies. In August

2020, she filed her first amended complaint, which did not include claims against the

insurance companies named in the original complaint. The amended complaint alleged

that Kevin had acted in the interests of or as an agent for Frost Limited Partnership and/or

the Ranch when Kevin kidnapped her. Specifically, Sherri argued that Kevin’s actions

were motivated, at least in part, by the Ranch’s goal of preventing Sherri from receiving

4 any part of the Ranch in the divorce. Margot and Dean Allen, as well as Frost Limited

Partnership and the Ranch, moved for summary judgment on the basis that Kevin’s

criminal actions were unrelated to them. The District Court granted the Allens’ motion for

summary judgment, and the claims against them were dismissed with prejudice. In an

October 2022 order, the District Court granted Frost Limited Partnership summary

judgment on all counts. Regarding the Ranch’s motion for summary judgment, the District

Court denied it in part, concluding that “reasonable minds could differ as to whether Kevin

was technically an employee of the [Ranch],” and therefore did not dismiss the count of

vicarious liability.

¶5 Following her husband’s death in 2015, Marilynn Frost became president, sole

shareholder, and director of the Ranch. The Ranch owns the cattle and ranching equipment,

but the land, however, is owned by the Frost Limited Partnership. The Ranch possesses a

1% general partnership interest, while the limited partnership percentages are: Marilynn

Frost 19%, Kevin Frost 40%, and Kevin’s brother, Randy Frost, 40%. Following Kevin’s

arrest for kidnapping, the Ranch paid $50,000 for his bail and provided an additional

$25,000 for his criminal defense attorney. Moreover, the decision to fund Kevin’s legal

fees with Ranch money was discussed and agreed upon by Marilynn and Randy. Marilynn

stated at trial that she used Ranch funds because she “didn’t have that kind of money in

[her] personal checking account at that time.” The Ranch, however, did have the money

because of a cattle sale held a few months previously. As the sole shareholder of the Ranch,

Marilynn is entitled to make distributions from its funds. Kevin and Marilynn have since

5 executed a promissory note where Kevin has agreed to pay back the funds she had loaned

on his behalf.

¶6 Kevin had an active role with the Ranch prior to the events of the kidnapping. Since

at least 1996, Kevin has held himself out as an employee of the Ranch. Since their father’s

illness, Kevin and Randy have overseen the day-to-day activities at the Ranch, which

include feeding the cattle and farming the land. Kevin has also helped in facilitating

business transactions for the Ranch. During the time he was released on bail prior to his

conviction and sentencing, and again after serving his sentence, Kevin worked at the Ranch

full-time and received a W-2, with a percentage of his wages going towards fulfilling his

obligations under the promissory note with Marilynn.

¶7 Kevin’s interest in the Frost Limited Partnership was a topic of discussion in Kevin

and Sherri’s divorce. Their respective counsel exchanged correspondence regarding the

status of the Frost Limited Partnership as marital property as early as December 2015. On
