STATE OF WISCONSIN IN COURT OF APPEALS DISTRICT IV

STATE OF WISCONSIN,

PLAINTIFF-RESPONDENT,

V.

TYLER C. SPETH,

DEFENDANT-APPELLANT.

APPEAL from a judgment and an order of the circuit court for Jefferson County: BENNETT J. BRANTMEIER, Judge. Affirmed.

Before Kloppenburg, Nashold, and Taylor, JJ.

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). No. 2025AP638-CR

¶1 PER CURIAM. A jury convicted Tyler Speth on seven counts of sexual assault-related conduct. Speth filed postconviction motions seeking judicial recusal and a new trial. The circuit court denied both motions. On appeal, Speth argues that the court erred in denying his recusal motion; that he is entitled to a new trial based on 14 instances of ineffective assistance of trial counsel and newly discovered evidence; and that he is entitled to a new trial in the interest of justice. We reject Speth’s arguments and, accordingly, affirm.

BACKGROUND

¶2 In November 2022, the State filed a criminal complaint charging Speth with exposing genitals to a child, causing a child to expose the child’s intimate parts, and sexual intercourse with a child. The charges arose from conduct that A.B. described in statements to Lake Mills Police Officer Brandon Hanley and in forensic interviews.1 In those statements, A.B. said that, between June and November 2022, when she was 16 years old and working at an insurance office in Lake Mills, her employer, Speth, offered to pay her for sexual favors and sexually assaulted her.

¶3 The case proceeded to a jury trial on seven counts as charged in the third amended information: soliciting a child for prostitution; exposing genitals to a child; two counts of sexual intercourse with a child; causing a child to expose the child’s intimate parts; and two counts of child enticement. The soliciting a child for prostitution count related to Speth’s alleged proposal and subsequent practice of paying A.B. for more hours than she actually worked in return for sexual

favors. Three of the counts—causing a child to expose the child’s intimate parts, one count of sexual intercourse with a child, and one count of child enticement— related to an incident in which Speth allegedly had penis-to-vagina intercourse with A.B. in the basement of the insurance office. The remaining three counts— exposing genitals to a child, one count of sexual intercourse with a child, and one count of child enticement—related to an incident in which Speth allegedly had A.B. perform oral sex on him in the sales office on the ground floor of the insurance office.

¶4 The trial took place over the course of five days in July and August 2023. During the trial, the jury heard testimony from 23 witnesses including A.B., A.B.’s mother, several of A.B.’s friends, several of A.B.’s former coworkers and other employees at the insurance office, police officers involved in the investigation, mental health professionals, a Wisconsin State Crime Laboratory DNA analyst, and Speth’s wife. Speth did not testify.

¶5 After the close of evidence, the circuit court allowed the State to file a fourth amended information. The fourth amended information switched the dates of the offenses for two of the counts. Defense counsel declined the court’s offer to reopen evidence for the defense to offer additional information or evidence in response to the fourth amended information.

¶6 The jury found Speth guilty on all seven counts as charged in the fourth amended information. The circuit court ordered concurrent sentences totaling five years of initial confinement and six years of extended supervision.

¶7 Speth subsequently moved the circuit court to recuse itself from all postconviction proceedings, based on the court’s alleged personal relationships

with two persons purported to be connected with A.B. The court issued an oral ruling denying the recusal motion.

¶8 Speth also filed a postconviction motion seeking a new trial based on multiple claims of ineffective assistance of trial counsel and on newly discovered evidence consisting of A.B.’s claims in the civil lawsuit that she filed against Speth after his conviction. The circuit court held a Machner hearing on Speth’s postconviction motion.2 At the hearing, the court heard testimony from several witnesses, including A.B.’s former coworkers and a former intern at the insurance office, Speth, and both of Speth’s trial counsel.

¶9 After further briefing and oral argument from the parties, the circuit court denied Speth’s postconviction motion in its entirety.

¶10 Speth appeals.

¶11 We will present additional pertinent background, testimony, and details of the circuit court’s rulings in our analysis of each of Speth’s appellate arguments.

DISCUSSION

I. Recusal

¶12 Speth argues that the circuit court erred in denying his motion for recusal, because the court’s purported “personal relationship with two individuals

2 See State v. Machner, 92 Wis. 2d 797, 804, 285 N.W.2d 905 (Ct. App. 1979). A Machner hearing is “[t]he evidentiary hearing to evaluate counsel’s effectiveness.” State v. Balliette, 2011 WI 79, ¶31, 336 Wis. 2d 358, 805 N.W.2d 334.

involved in this prosecution gives the appearance of bias.” We conclude that Speth fails to show that the circumstances presented in the record provide a basis for rebutting the presumption of the court’s impartiality.

¶13 “‘The right to an impartial judge is fundamental to our notion of due process.’” Miller v. Carroll, 2020 WI 56, ¶15, 392 Wis. 2d 49, 944 N.W. 2d 542 (quoted source omitted). “We presume that a judge has acted fairly, impartially, and without bias.” Id., ¶21. “To overcome that presumption, the burden is on the party asserting judicial bias to show bias by a preponderance of the evidence.” Id. “In determining whether a defendant’s due process right to trial by an impartial and unbiased judge has been violated, Wisconsin courts have taken both subjective and objective approaches[.]” State v. Herrmann, 2015 WI 84, ¶26, 364 Wis. 2d 336, 867 N.W.2d 772.

¶14 The question of subjective bias is whether the judge has determined that the judge cannot be impartial. State v. McBride, 187 Wis. 2d 409, 415, 523 N.W.2d 106 (Ct. App. 1994). Here, Speth does not contend that the judge determined that he was subjectively biased. Rather, he contends that the judge was objectively biased.

¶15 In determining whether a judge is objectively biased, “[w]e ask whether there is ‘a serious risk of actual bias—based on objective and reasonable perceptions.’” Miller, 392 Wis. 2d 49, ¶24 (quoted source omitted).
