OAR 137-003-0050: Evidentiary Rules

(1) Evidence of a type commonly relied upon by reasonably prudent persons in the conduct of their serious affairs shall be admissible. (2) Irrelevant, immaterial, or unduly repetitious evidence shall be excluded, and privileges afforded by Oregon law shall be recognized by the presiding officer. (3) All offered evidence, not objected to, will be received by the presiding officer subject to the officer’s power to exclude irrelevant, immaterial, or unduly repetitious matter. (4) Evidence objected to may be received by the presiding officer. Rulings on its admissibility, if not made at the hearing, shall be made on the record at or before the time a final order is issued. (5) The presiding officer shall accept an offer of proof made for excluded evidence. The offer of proof shall contain sufficient detail to allow the reviewing agency or court to determine whether the evidence was properly excluded. The presiding officer shall have discretion to decide whether the offer of proof is to be oral or written and at what stage in the proceeding it will be made. The presiding officer may place reasonable limits on the offer of proof, including the time to be devoted to an oral offer or the number of pages in a written offer.
