Expert Witness Services in Portland

Multnomah County Circuit Court handles most substantial Oregon civil litigation and sets the practical tone for the state. Expert practice here runs on the OEC 702 framework developed in State v. Brown and refined in State v. O'Key — a standard that is neither Daubert nor Frye, and that is regularly mischaracterised as one or the other.

What admissibility standard applies in Portland?

Oregon evaluates expert and scientific evidence under OEC 702 through the framework the Oregon Supreme Court developed in State v. Brown and refined in State v. O'Key. It is related to the federal Daubert inquiry without being identical to it, and it is distinct again from Washington's Frye test across the Columbia.
