Barber v. Page
United States Supreme Court
390 U.S. 719 (1968)
Barber and Woods were jointly tried for armed robbery and shared counsel, Parks, until Woods waived self-incrimination to testify at the preliminary hearing, incriminating Barber; Parks (now representing only Barber) did not cross-examine Woods. At Barber's trial seven months later, Oklahoma (plaintiff) introduced Woods's preliminary-hearing transcript, claiming Woods was unavailable because he was in federal prison in Texas — but the state made no effort to actually secure Woods's testimony at trial, even though federal law allowed courts to issue a writ to produce federal prisoners as witnesses. Barber was convicted and, after unsuccessful state appeals, sought federal habeas relief.
Whether the Confrontation Clause's unavailability exception applies when the government has not made a good-faith effort to determine whether the witness is actually unavailable.
