STATE OF WISCONSIN IN COURT OF APPEALS DISTRICT III

STEPHAN LANE,

PLAINTIFF-RESPONDENT,

V.

RILEY KUMMET AND ZACK DIECKMAN,

DEFENDANTS-APPELLANTS,

RUSK COUNTY,

DEFENDANT.

APPEAL from an order of the circuit court for Rusk County: BENJAMIN J. LANE, Judge. Affirmed and cause remanded for further proceedings.

Before Stark, P.J., Hruz, and Gill, JJ. No. 2024AP998

Per curiam opinions may not be cited in any court of this state as precedent

or authority, except for the limited purposes specified in WIS. STAT. RULE 809.23(3).

¶1 PER CURIAM. Riley Kummet and Zack Dieckman appeal a nonfinal order denying their motion for summary judgment on claims brought against them by Stephan Lane. On appeal, Kummet and Dieckman contend that they are entitled to qualified immunity on Lane’s claim against them under 42 U.S.C. § 1983.1 Like the circuit court, we conclude that genuine issues of material fact exist regarding Kummet and Dieckman’s entitlement to qualified immunity. We therefore affirm the order denying summary judgment on that issue and remand for further proceedings consistent with this opinion.

BACKGROUND

¶2 In January 2021, both Kummet and Dieckman were employed as investigators with the Rusk County Sheriff’s Office. At that time, the Rusk County Sheriff’s Office was investigating reports regarding a marijuana grow operation at Lane’s residence, which was located on Fritz Avenue in Ladysmith, Wisconsin.

¶3 As part of that investigation, on January 11, 2021, Kummet and Dieckman performed a “knock and talk” at Lane’s residence. A “knock and talk” is an investigative technique in which

1 On June 28, 2024, this court granted Kummet and Dieckman’s petition for leave to appeal the circuit court’s nonfinal order “as to the limited issue of whether the circuit court erred by denying [Kummet and Dieckman’s] motion for summary judgment on the issue of qualified immunity.” See WIS. STAT. RULE 809.50(3) (2023-24); see also Arneson v. Jezwinski, 206 Wis. 2d 217, 231, 556 N.W.2d 721 (1996).

police go to people’s residences, with or without probable cause, and knock on the door to obtain plain views of the interior of the house, to question the residents, to seek consent to search, and/or to arrest without a warrant, often based on what they discover during the “knock and talk.”

City of Sheboygan v. Cesar, 2010 WI App 170, ¶9 n.5, 330 Wis. 2d 760, 796 N.W.2d 429 (citation omitted).

¶4 Lane’s residence had a front door on the northern side of the house—that is, the side of the house facing Fritz Avenue. There was also a door on the back, southern side of the house, leading into a structure that the parties refer to as a “breezeway.” The breezeway had two windows on its south wall and had siding matching the rest of the house. The backyard area surrounding the breezeway on the southern side of the house was enclosed with a fence, which had a gate with a latch. There was a parking area to the west of the house, outside the fenced-in backyard on the south side of the residence.

¶5 When Kummet and Dieckman went to Lane’s residence to perform a “knock and talk,” they approached the southern door leading into the breezeway, rather than the front door on the north side of the house. They entered the fenced area on the south side of the residence through the gate, which they stated was latched, but not locked. They then proceeded into the breezeway and made their way to a closed door leading into the house, which had a Ring doorbell on it. After Kummet rang the doorbell, Lane opened the door leading from the breezeway into the house. At that point, Kummet could smell marijuana, and he also saw three planter pots inside the house that “had large stems that appeared to be marijuana already harvested.” Lane quicky shut the door behind him and then walked outside of the breezeway, into the backyard, to speak with Kummet and Dieckman.

3 No. 2024AP998

¶6 Based in part on his observations during the “knock and talk,” Kummet subsequently applied for—and received—a warrant to search Lane’s residence. During the execution of the search warrant, officers seized “THC plants that smelled of raw marijuana,” plantlike material that field-tested positive for THC, and other drug-related items. The State then charged Lane in Rusk County Case No. 2021CF24 with manufacture or delivery of THC, possession with intent to deliver THC, misdemeanor bail jumping, and possession of drug paraphernalia.

¶7 In his criminal case, Lane moved to suppress the evidence seized during the search of his residence, arguing that Kummet and Dieckman conducted an unlawful, warrantless search within the curtilage of his home when they entered the home’s breezeway to perform a “knock and talk.” Following a suppression hearing, the State conceded that Kummet and Dieckman had unlawfully entered the curtilage of Lane’s home without a warrant and that the subsequent search warrant was issued based on information obtained during the prior, unlawful search. The State therefore joined Lane’s motion to suppress. The circuit court in Lane’s criminal case granted the suppression motion and dismissed the charges against Lane.

¶8 Lane then filed the instant lawsuit against Kummet, Dieckman, and Rusk County, asserting a claim under 42 U.S.C. § 1983 based on Kummet and Dieckman’s alleged violation of Lane’s rights under the Fourth Amendment to the

4 No. 2024AP998

United States Constitution and article 1, section 11 of the Wisconsin Constitution.2 Lane also asserted state law claims for trespass and invasion of privacy. In addition, he alleged that Rusk County was liable for Kummet and Dieckman’s actions under the doctrine of respondeat superior.

¶9 Kummet, Dieckman, and Rusk County moved for summary judgment, arguing that: (1) Lane’s § 1983 claim failed as a matter of law because the undisputed facts showed that Kummet and Dieckman did not violate Lane’s constitutional rights (2) alternatively, Kummet and Dieckman were entitled to qualified immunity with respect to the § 1983 claim; (3) Lane’s state law claims failed as a matter of law; (4) alternatively, Kummet and Dieckman were entitled to governmental immunity with respect to the state law claims, pursuant to WIS. STAT. § 893.80(4); and (5) Rusk County was not liable for Lane’s state law claims under the doctrine of respondeat superior. Lane filed a response opposing the summary judgment motion, and both sides filed affidavits in support of their respective positions.

¶10 With respect to Lane’s § 1983 claim, the circuit court concluded that genuine issues of material fact existed as to whether Kummet and Dieckman had violated Lane’s constitutional rights and whether they were entitled to qualified immunity for any such violation. The court further concluded that genuine issues of material fact existed regarding Lane’s state law claims. The court therefore denied the defendants’ motion for summary judgment with respect to those issues.
