COA issues first impression decision on constitutionality of warrant to search contents of smartphone, holds “the warrant must specify the particular items of evidence to be searched for and seized from the [smart]phone,” and its authorization must be “limited to the time period and information or other data for which probable cause has been properly established… in the warrant’s supporting affidavit”
State v. Emil L. Melssen, 2024AP1942-CR, 11/20/25, District IV (recommended for publication); case activity (including briefs)
Emil Melssen appeals from a judgment of conviction following a jury trial, in which he was convicted of possession of methamphetamine with intent to deliver and related charges. He argues that the evidence was insufficient to sustain his conviction and the circuit court erroneously denied his motion to suppress evidence obtained in the execution of two search warrants. COA rejects Melssen’s sufficiency argument, but concludes that the warrant to search his smartphone violated the Fourth Amendment because it was overbroad and not carefully tailored to its justifications. The court remands for a determination on the remedy.
Eastern District holds that investigators violated 4th Amendment when they viewed suspected child pornography identified via “hash matching;” holds that good faith does not apply
United States of America v. Peter Braun, 24-CR-164 (E.D. Wis. 9/3/25).
In an interesting Fourth Amendment case, the Court holds that law enforcement violated Braun’s rights when it viewed suspected child pornography without a search warrant when that child pornography had not been previously viewed by an employee of an ESP.

City of Monona v. Erick J. Erickson, 2024AP312, District IV, 5/30/25 (one-judge decision; ineligible for publication); case activity
The COA affirmed Erick J. Erickson’s conviction following a bench trial for operating with a prohibited alcohol concentration and revocation of his operating privileges because he unreasonably refused to submit to a preliminary breath test (PBT). COA found that the circuit court correctly denied Erickson’s motion to suppress because police had probable cause to request the PBT and probable cause to arrest Erickson.

State v. Laquanda N. Strawder, 2022AP2112, 1/17/24, District 1 (one-judge decision; ineligible for publication); case activity (including briefs)
The circuit court held that police lacked probable cause to arrest Strawder for OWI and suppressed the resulting evidence, including her breath test results. The state appealed, claiming the circuit court’s factual findings and analysis were so lacking the court of appeals should review the factual record ab initio. The court of appeals thinks the trial court did the proper analysis and made sufficient factual findings, but disagrees with its legal conclusion. In the facts as found by the trial court, the court of appeals sees probable cause to arrest, and thus reverses and remands for the prosecution to continue.
COA reverses order suppressing evidence obtained after traffic stop
State v. Lauren Dannielle Peterson, 2023AP890-CR, 12/29/23, District 4 (one-judge case, ineligible for publication); case activity
Peterson’s circuit court win is short-lived after the court of appeals concludes that reasonable suspicion existed to initiate an OWI investigation and probable cause existed to ask Peterson to perform a preliminary breath test (PBT).
Defense win: taking man from home in squad, leaving him cuffed inside for 30 minutes was unlawful arrest
State v. Nicholas Anthony Stilwell, 2022AP1839, 7/20/23, District 4 (one-judge decision; ineligible for publication); case activity (including briefs)
This case has facts remarkably like those of State v. Cundy, a recommended-for-publication case the court of appeals decided the week before. Police received a report of a hit-and-run of a parked vehicle, and learned the truck that did the hitting and running was registered to Stilwell. They went to Stilwell’s apartment and found the truck parked nearby. They buzzed Stilwell and he answered the door. They eventually entered the apartment and determined, including by the use of a PBT, that Stilwell was intoxicated, though he denied having driven his truck. They cuffed him, told him he was being “detained,” and took him to the crash scene, where after about 30 minutes they secured other evidence that Stilwell had driven his truck; they thus arrested him.
