In United States v. McDonald, 55 M.J. 173 (C.A.A.F. 2001), the CAAF has held that the Sixth Amendment confrontation right does not apply at sentencing, but that the Fifth Amendment does.
Here is an interesting case from the Supreme Court of Arkansas, Vankirk v. State, which applies the confrontation right to a jury (members) case. Here are Prof. Friedman’s thoughts:
I think this case is a good illustration of the issue of confrontation rights in sentencing. Suppose the girl had testified live at the sentencing proceeding, but at the conclusion of direct, as defense counsel was rising to cross-examine, the judge said, "You are excused. We have no need for cross-examination, so I will not allow it." I think that would plainly be unconstitutional – if not under the Confrontation Clause, because the Clause is construed not to apply to this type of proceeding, then under the Due Process Clause. So should the result be any different when the witness testifies just outside the courtroom on videotape and the tape is played at the proceeding? When I refer to the speaker as a witness and say that she is testifying, I am drawing on one of the essential points of Crawford: Simply because a person (such as Sylvia Crawford) speaks out of court does not mean that she is not testifying, and indeed the central focus of the Confrontation Clause is to require that testimony be given in court, under prescribed procedures[.]
