Whether the Sixth Amendment right to confront and cross-examine adverse witnesses is binding on the States through the Fourteenth Amendment.
Holding
Yes. The right of confrontation is fundamental to a fair criminal trial and is enforceable against the States through the Fourteenth Amendment.
Reasoning
The Court followed the incorporation approach reflected in Gideon v. Wainwright and Malloy v. Hogan: a guarantee in the Bill of Rights that is fundamental and essential to a fair trial is made obligatory on the States by the Fourteenth Amendment. The Court held that confrontation meets that standard.
Confrontation necessarily includes the right to cross-examine the witnesses against the accused. Cross-examination is a central means of exposing falsehood, testing reliability, and developing the truth before the factfinder. The Framers' placement of the right in the Sixth Amendment confirmed its fundamental character.
The Court's precedents had repeatedly described confrontation and cross-examination as essential protections of life, liberty, due process, and a fair criminal trial. Earlier broad statements that the Sixth Amendment did not apply to state proceedings could no longer control after decisions such as Gideon had made particular Sixth Amendment guarantees applicable to the States.
Once incorporated, the confrontation guarantee applies against state action by the same standards that govern federal prosecutions. A State therefore may not use procedures that would violate the Sixth Amendment in federal court.
