KERN, Justice

[¶1.] Doug Gantvoort (Doug) sued his former wife, Mary Ranschau (Mary),

and her attorney, David Strait (Strait), after Mary placed a hidden recording device

in Doug’s office during their tumultuous divorce. Strait accepted fifty-one

recordings that Mary made of Doug, saved them onto his computers, and attempted

to introduce two of them into evidence during the divorce trial. One of the

recordings captured Doug’s comments while viewing pornography. In another, he

discussed his net worth and expressed love for his mistress. Doug brought claims

against Strait asserting he intentionally invaded Doug’s privacy, aided and abetted

Mary in her invasion of his privacy, and, by this conduct, engaged in a civil

conspiracy with Mary. The circuit court granted summary judgment in favor of

Strait on all counts. 1 We reverse the entry of summary judgment on Doug’s claim

1. Doug, his mistress, Dorothy Novak, and his friend, Keith Diekman, initially filed suit against Strait. On June 21, 2019, all three plaintiffs filed a notice of appeal of the circuit court’s entry of summary judgment. This appeal was dismissed pursuant to SDCL 15-26A-3 for failing to appeal from an order appealable as a matter of right. The circuit court subsequently filed a “Judgment and Final Order Dismissing Claims and Taxing Costs,” from which only Doug filed a notice of appeal on February 27, 2020. However, the notice of appeal was signed by Dorothy’s attorneys. Yet, in the appellate briefs, it appears that Doug is the only appellant. The title pages to appellant’s briefs list Doug as “Plaintiff/Appellant,” Dorothy as only “Plaintiff,” and do not list Keith at all. The appellant’s briefs refer to the “Appellant” in the singular throughout and make no arguments on Dorothy’s behalf; in fact, she is referenced only in passing a few times. Therefore, it appears that Dorothy is not an appellant in this case. Even if she were, her potential arguments are waived by her failure to present any arguments or present her claims in the briefs. See Duerre v. Hepler, 2017 S.D. 8, ¶ 28, 892 N.W.2d 209, 220 (“It is well-settled that the failure to brief an issue and support an argument with authority waives the right to have this Court review it.” (citations omitted)).

against Strait in Count 2 for aiding and abetting, but we affirm the entry of

summary judgment as to Counts 1 and 3.

Factual and Procedural Background

[¶2.] Doug and Mary married in 1996. During the course of their marriage,

they owned and operated a specialty restoration business in Clear Lake, South

Dakota, refurbishing antique tractors and vehicles. Mary worked as the sole

employee of the business following a motorcycle accident Doug had in 2006.

Sometime in late 2014, Mary began to suspect that Doug was having an affair.

Mary sought advice from private investigators about how to conduct electronic

surveillance of Doug. Thereafter, Mary purchased a voice-activated audio recording

device and hid it in the windowsill of Doug’s office. 2 On November 30, 2014, Mary

began recording Doug at times when she knew he would be in the office. She would

place the recording device in the room and return later to collect it and listen to the

recordings. 3 Mary made a total of fifty-one recordings.

2. The device would automatically turn on and start recording when someone in the room spoke or made a sound, and it would turn off when no noise was detected in the room.

3. SDCL 23A-35A-20(1)–(2), which criminalizes recordings made without consent provides that:

[A] person is guilty of a Class 5 felony who is not:

(1) A sender or receiver of a communication who intentionally and by means of an eavesdropping device overhears or records a communication, or aids, authorizes, employs, procures, or permits another to overhear or record, without the consent of either a sender or receiver of the communication;

(continued . . .) -2- #29265

[¶3.] Because Doug and Mary restored large antique items, the couples’

business consisted mostly of an open shop area with a small, enclosed office area.

The shop area had one large door which was used most often. The office area had

two doors, one leading into the shop and another allowing outside access. The door

leading into the shop did not have a lock, but the outside door did have a lock to

which Mary had a key. The office also had windows, a desk, a computer, and other

office equipment. The windows had cardboard on the inside preventing people from

seeing into the office. Doug frequently spent late evenings, and occasionally, he

spent nights in the office as it also had kitchen appliances, a restroom, and shower

facilities. Although Mary testified at her deposition that the office was Doug’s “man

cave, kind of,” she also testified that it was “not a man cave. It’s our office. It’s the

shop. It’s been a long time since it’s been really opened up to the public, but yet we

still have a lot of people come in . . . and they’ll walk around.” (Emphasis added.)

[¶4.] Mary’s recordings consisted mostly of Doug’s side of telephone

conversations occurring late at night, some of which allegedly involved his mistress,

________________________ (. . . continued) (2) A person present during a conversation or discussion who intentionally and by means of an eavesdropping device overhears or records the conversation or discussion, or aids, authorizes, employs, procures, or permits another to overhear or record, without the consent of a party to the conversation or discussion[.]

Further, placing such a device is a class one misdemeanor. SDCL 22-21-1(2), provides in part that:

No person may, except as authorized by law . . . [i]nstall in any private place, without the consent of the person or persons entitled to privacy there, any device for observing, photographing, recording, amplifying, or broadcasting sounds or events in such place, or uses any such unauthorized installation.

but one of the recordings captured the sound of Doug masturbating while he viewed

pornography in his office. After reviewing the first few recordings, Mary believed

Doug’s conversations confirmed her suspicions that Doug was having an affair

because he was “setting up trips for weekends” with a woman and spoke about

building a house for her. Mary contacted attorney Strait about filing for divorce.
