Oregon Revised Statutes Chapter 138 § 138.670 — Admissibility,

Admissibility, at new trial, of testimony of witness at first trial. In the event that a new trial is ordered as the relief granted in a proceeding pursuant to ORS 138.510 to 138.680, a properly authenticated transcript of testimony in the first trial may be introduced in evidence to supply the testimony of any witness at the first trial who has since died or who cannot be produced at the new trial for other sufficient cause. Such transcript shall not be admissible in any other respect, except that the transcript of testimony of a witness at the first trial may be used at the new trial to impeach the testimony at the new trial by the same witness.
