No. 22-899Jun 21, 2024Crime and Law EnforcementVacated and remanded

The question

Whether the Confrontation Clause bars the prosecution from introducing an absent forensic analyst's statements through a testifying expert who relies on them as the basis for the expert's own opinion.

Smith v. Arizona

What the Court decided

The Court held that when a testifying expert conveys an absent analyst's out-of-court statements to support the expert's opinion, and those statements support the opinion only if they are true, the statements are admitted for their truth. A state evidentiary rule labeling such statements "basis" evidence rather than evidence offered for its truth does not control the constitutional inquiry, which courts must conduct independently. Because the absent analyst's factual statements were admitted for their truth and the defendant had no chance to cross-examine her, the Confrontation Clause was implicated. The Arizona court's contrary ruling could not stand, and a remaining question was left open on remand.

The Court's opinion

Kagan, joined by Sotomayor, Kavanaugh, Barrett, Jackson, Thomas, Gorsuch

The Court held that an out-of-court statement conveyed by a testifying expert to support the expert's opinion is offered for its truth when the statement supports the opinion only if true. State evidentiary rules authorizing admission for the limited purpose of showing the basis of the opinion do not control; courts must independently determine whether a statement is admitted for its truth. Here the absent analyst's factual statements were admitted for their truth, the defendant could not cross-examine her, and the Confrontation Clause was therefore implicated. Sotomayor, Kavanaugh, Barrett, and Jackson joined in full; Thomas and Gorsuch joined as to Parts I, II, and IV.
