Summary: written with AI from the case record.

What it's about
Supreme Court to review her claim that her trial violated her right to question witnesses against her because a pathologist relied partly on a lab technician’s out-of-court evidence about a child’s death, and that Idaho’s highest court misapplied federal law. The Court refused to hear the case (denied review), so it did not decide whether her claims were correct.
The dispute arose from expert testimony at Stanfield’s trial and her later challenge to how Idaho’s courts handled it.
Question presented
1. Whether Katherine Stanfield was deprived of her Sixth Amendment right to confront her accusers when the trial court allowed the State’s expert pathologist to offer her opinion that a child had died from severe, non-accidental trauma to his brain, when that opinion that was based, in large part, on testimonial evidence prepared out-of-court by a lab technician. 2. Whether the Idaho Supreme Court’s opinion on the Sixth Amendment question was contrary to or an unreasonable application of clearly established federal law as determined by this Court.
