What it's about

This applies when the jury is instructed to consider the confession only against the codefendant, even if context implicates the defendant.

The case defines when the Confrontation Clause right to cross-examine witnesses limits evidence in joint trials.

Question presented

Does admitting a codefendant’s redacted out-of-court confession that immediately inculpates a defendant based on context violate the Confrontation Clause of the Sixth Amendment?

What the Court decided

Holding

The Confrontation Clause was not violated by the admission of a nontestifying codefendant’s confession that did not directly inculpate the defendant and was subject to a proper limiting instruction. Pp. 5– 17. (a) Stillwell’s formal, Mirandized confession to authorities is testimonial and thus falls within the ambit of the Sixth Amendment’s Confrontation Clause, which forbids the introduction of out-of-court “testimonial” statements unless the witness is unavailable and the defendant has had the chance to cross-examine the witness previously. See Crawford v. Washington , 541 U. S. 36, 52–54. The Clause, however, applies only to witnesses “against the accused.” Id. , at 50. Affirmed.

From the opinions

“The Confrontation Clause was not violated by the admission of a nontestifying codefendant’s confession that did not directly inculpate the defendant and was subject to a proper limiting instruction.”

— Justice Clarence Thomas(majority)

“This Court’s precedent bars the government from using John’s confession in that way.”

— Justice Elena Kagan(dissent)

What's next

Lower courts will apply this rule when deciding whether redacted codefendant confessions can be used at joint trials. Trial judges must assess the wording of the confession and give proper limiting instructions to jurors.

Why it matters

For example, jurors may hear that evidence against the confessing codefendant but must follow an instruction not to use it against the other defendant.
