Oregon Evidence Code – 2026
Chapter 40 of the Oregon Revised Statutes is the Oregon Evidence Code. It governs the admissibility of evidence in Oregon courts: general provisions and judicial notice, presumptions, relevance and its limits, privileges, witness competency and impeachment, opinion and expert testimony, hearsay and its exceptions, authentication and identification, and the contents of writings, recordings and photographs. Most of its sections carry two numbers — ORS 40.160 is also Evidence Rule 401 — and Oregon lawyers cite both, so each section is listed by its ORS number with the Evidence Rule number shown in its title.
