APPEAL and CROSS-APPEAL from a judgment and an order of the circuit court for Milwaukee County: GWENDOLYN G. CONNOLLY, Judge, and WILLIAM W. BRASH, III, Reserve Judge. Affirmed.

Before Donald, C.J., Colón, P.J., and Geenen, J.

¶1 DONALD, C.J. Auto-Owners Insurance Company and Treider Industries, Inc. (Treider) appeal from the judgment and order finding it negligent in Walter McGuinness’s death and awarding $1,665,000 in damages in favor of the Estate of Walter McGuiness and Judith McGuinness, Walter’s wife. The Estate and Judith (collectively the Estate) cross-appeal from the same, arguing that the statutory cap on loss of society and companionship pursuant to WIS. STAT. § 895.04(4) (2023-34)1 is unconstitutional. Treider argues that there was insufficient evidence to support the verdict and damages award; the testimony of four expert witnesses should have been excluded; a spoliation jury instruction was unwarranted; and a new trial should be ordered as a result of the Estate’s prejudicial arguments. We conclude that these arguments fail. We further conclude that the statutory cap is constitutional. Therefore, we affirm.

BACKGROUND

¶2 This case arises from Walter’s fatal injury caused by falling on the basement stairway in his home on October 5, 2020. It is undisputed that prior to the incident, the McGuinnesses hired Treider to paint the interior of their home. In preparation, employees removed the handrail from the wall in the stairway to the McGuinnesses’ basement on October 2. On October 5, Judith and Daniel

McGuinness, their son, were in the house and heard a thump when Walter fell. Judith and Daniel found Walter and called 911 for emergency help, but Walter died as a result of his head and neck injuries sustained from the fall.

¶3 The Estate filed an action for negligence in February 2022. It argued that Treider was negligent for removing the handrail from the stairway for multiple days while painting the McGuinnesses’ home. The Estate named experts to testify to safety standards related to stairs, handrails, and painting; the mechanics and timing of Walter’s fall; and Walter’s cause of death and conscious pain and suffering. Treider moved to preclude several expert witnesses in a Daubert2 challenge, asserting that the experts could not support opinions on how and why Walter fell and whether he experienced conscious pain and suffering. The circuit court denied the motion, concluding the expert witnesses were sufficiently reliable and relevant.3

¶4 The case proceeded to trial. An issue arose when Bernard Treider, the owner of the company, and Max Netschajiwsky, the Treider employee who removed the handrail, claimed for the first time at trial that Netschajiwsky taped over the doorway to warn the household about the missing handrail. The Estate impeached both men’s testimony with their deposition testimony that did not mention taping the doorway. Bernard also testified that he received a photograph from Netschajiwsky of the taped doorway; however, he deleted it. Further, Bernard testified that he called Judith and Walter and updated them on the

painting job, informed them that the handrail was off, and was told they would stay out of the basement.

¶5 Judith denied that Netschajiwsky and Bernard told her or Walter that the handrail had been removed and denied that warning tape had been placed across the opening to the stairway. Treider did not disclose any photographs in discovery, and during Bernard’s deposition, he stated only that Netschajiwsky might have photographs. As a result, the Estate requested, over Treider’s objection, that the circuit court give a spoliation instruction that the jury could “infer that these actions unfavorably affect [Bernard’s] credibility.”

¶6 The jury found that Treider was negligent on or prior to the date of Walter’s fall, and its negligence was a cause of Walter’s injuries. While the jury also found Walter negligent and that his negligence was a cause of his injuries, the jury attributed 90% of the negligence to Treider and 10% to Walter. The jury awarded $1.5 million to the Estate as compensation for Walter’s pain and suffering from the accident up to the time of his death and $5 million to Judith for loss of society and companionship.

¶7 The parties filed motions after verdict. Treider argued the circuit court should change two of the jury’s verdict answers: that Treider’s negligence was a cause of Walter’s injuries because there was no evidence of the cause of Walter’s fall presented at trial; and that the award for pain and suffering should be reduced to $0 because the evidence showed that Walter experienced pain and suffering for less than 1.2 seconds. The Estate argued that the circuit court should

4 No. 2024AP1844

not apply the statutory cap on loss of society and companionship pursuant to WIS. STAT. § 895.04(4) because it is unconstitutional.4

¶8 The circuit court denied both motions. After reducing the awards for Walter’s 10% contributory negligence and the statutory cap, the court entered a judgment of $1.35 million for the Estate and $315,000 for Judith. This appeal and cross-appeal follow.

DISCUSSION

¶9 Treider argues that the judgment should be reversed and a new trial ordered. We group its arguments under four issues: sufficiency of the evidence of causation and damages, admission of expert witness testimony, the spoliation jury instruction, and prejudicial arguments by the Estate. In its cross-appeal, the Estate argues that WIS. STAT. § 895.04(4) is unconstitutional.

I. Treider’s Arguments

A. Sufficiency of the Evidence

¶10 Treider argues that the jury resorted to impermissible speculation in reaching its verdicts. First, it asserts there was no evidence presented on the causation of Walter’s fall. Second, it contends that Walter’s pain and suffering occurred over such a short time span that the jury was incapable of fairly and reasonably determining damages.

4 Judith’s recovery for the loss of society and companionship damages awarded by the jury is capped by WIS. STAT. § 895.04(4). The statute caps the damages as “not to exceed $500,000 per occurrence in the case of a deceased minor, or $350,000 per occurrence in the case of a deceased adult[.]”
