In a significant ruling, the District Court of Appeal of Florida reversed a judgment in a landlord-tenant dispute, impacting how juror bias and expert testimony are handled in court. The case, Stout v. Cassity, No. 2D2025-1111, involved Jessica Stout, a tenant, who appealed a jury's decision favoring her landlord, Loretta Cassity. The court's decision on August 28, 2026, underscores the importance of fair jury selection and the admissibility of expert evidence in civil cases.
The case began when Jessica Stout rented a residential unit from Loretta Cassity. Shortly after moving in, Stout reported a dripping sound from the ceiling, which led to maintenance work by Cassity's son. However, the situation escalated when a heavy storm caused a leak from the kitchen ceiling. Cassity's son attempted to investigate by poking a hole in the ceiling, after which a portion of the ceiling collapsed on Stout, resulting in injuries.
The dispute arose over whether Cassity's son adequately warned Stout about the dangers posed by the damaged ceiling. Stout claimed she received no warning, while Cassity contended that her son did warn Stout. Following the incident, Stout filed a lawsuit against Cassity, both individually and as trustee for the Loretta Cassity Revocable Trust, seeking damages for her injuries.
The case reached trial, where Stout's counsel faced challenges regarding the exclusion of certain evidence and the denial of a juror interview after the verdict was rendered. Stout's legal team argued that a juror who had not disclosed her landlord experience during voir dire had potentially biased the jury's decision. The trial court denied the request for a juror interview, which Stout's team believed was necessary to explore this potential bias.
In its ruling, the District Court of Appeal found that the trial court erred in denying the juror interview and limiting the testimony of Stout's expert witness, R.J. Koning, a certified contractor. The court stated, "The trial court should have granted the juror interview because Tenant satisfied all three prongs of the De La Rosa test." This test assesses whether juror nondisclosure warrants a new trial based on materiality, concealment, and diligence.
The court emphasized that the juror's failure to disclose her landlord experience was significant, particularly since Stout's counsel had repeatedly questioned potential jurors about their landlord or property management experience. The court noted that had Stout's counsel known about the juror's background, they might have exercised a peremptory strike against her.
Regarding the expert testimony, the court ruled that the trial court had improperly limited Koning's testimony. Stout's team had disclosed Koning as an expert witness well before the trial, but the trial court restricted his testimony to a narrow interpretation of a two-page document he provided. The court stated, "Landlord's failure to seek this information was not a valid basis to exclude Tenant's expert's opinions at trial, particularly after Landlord deposed the expert during a break in trial."
The ruling highlights the importance of allowing full and fair testimony from expert witnesses, especially in cases where the evidence is critical to the outcome. The court concluded that the exclusion of Koning's testimony was harmful to Stout's case, necessitating a new trial.
The court's decision has broader implications for future landlord-tenant disputes and civil litigation in Florida. It reinforces the need for transparency during jury selection and proper procedures for admitting expert testimony. The ruling also serves as a reminder to litigants about the importance of thorough pretrial discovery and the potential consequences of failing to adequately prepare.
Moving forward, the case will be sent back to the lower court for a new trial, where both parties can present their evidence and arguments anew. The court's decision does not appear to be subject to further appeal, as it addresses procedural issues rather than substantive legal principles.
Overall, the Stout v. Cassity ruling emphasizes the judicial system's commitment to ensuring fair trials and the proper administration of justice in civil cases.
