Michigan v. Thorpe (Opinion on Application)Annotate this Case
In these consolidated cases, the Michigan Supreme Court addressed the propriety and scope of expert testimony in cases alleging child sexual abuse. In Thorpe, the Court addressed the admissibility of testimony from an expert in the area of child sexual abuse and disclosure about the rate of false reports of sexual abuse by children to rebut testimony elicited on cross-examination that children can lie and manipulate. In Harbison, the Court addressed the admissibility of expert testimony from an examining physician that “diagnosed” the complainant with “probable pediatric sexual abuse” despite not having made any physical findings of sexual abuse to support that conclusion. In Thorpe, the Court held expert witnesses may not testify that children overwhelmingly do not lie when reporting sexual abuse because such testimony improperly vouches for the complainant’s veracity. And because Thorpe established that this testimony more likely than not affected the outcome of the case, the Supreme Court reversed the Court of Appeals and remanded to the circuit court for a new trial. In Harbison, the Supreme Court held that examining physicians could not testify that a complainant has been sexually assaulted or has been diagnosed with sexual abuse without physical evidence that corroborates the complainant’s account of sexual assault or abuse because such testimony vouches for the complainant’s veracity and improperly interferes with the role of the jury. Because the Supreme Court concluded this was plain error, affected Harbison’s substantial rights, and seriously affected the integrity of his trial, it reversed the Court of Appeals and remanded for a new trial.
