Whether the Confrontation Clause bars a State from admitting a testifying witness’s prior inconsistent out-of-court statements as substantive evidence merely because the defendant could not cross-examine the witness when the statements were originally made.
Holding
No. The Confrontation Clause does not require exclusion when the declarant testifies at trial, acknowledges or can be shown to have made the prior statement, and is subject to full and effective cross-examination about both the earlier and current accounts.
Reasoning
California’s evidence rule reflected a permissible departure from the traditional hearsay rule. Hearsay doctrine and the Confrontation Clause protect related interests, but they are not identical. A State’s decision to admit evidence that traditional hearsay rules might exclude does not automatically create a constitutional violation.
Historically, the central evil targeted by the Confrontation Clause was trial by ex parte affidavits, depositions, and similar evidence in place of a live witness. The Clause principally protects the accused’s opportunity to confront the witness before the factfinder rather than constitutionalizing every common-law hearsay restriction.
When the declarant appears at trial, many ordinary hearsay dangers are substantially reduced. The witness must, under oath, affirm, deny, or explain the earlier statement; the defendant can cross-examine the witness about perception, memory, motive, and the inconsistency; and the factfinder can observe the witness’s demeanor while assessing the competing accounts.
The Court rejected the California Supreme Court’s categorical view that cross-examination must be contemporaneous with the prior statement. Where a witness has changed his story in a way favorable to the defendant, later cross-examination may be especially useful because the witness can provide explanations that undermine the earlier accusation.
Earlier confrontation cases concerned absent declarants or declarants who could not be effectively examined, such as the accomplice in Douglas v. Alabama and the non-testifying codefendant in Bruton v. United States. Those cases did not require exclusion of a prior statement when its maker appears and can be questioned at trial about its truth.
