The Oregon Revised Statutes are the codified laws of the State of Oregon. The ORS is published every two years. Each edition incorporates all laws, and changes to laws, enacted by the Legislative Assembly through the odd-numbered year regular session referenced in the volume titles for that edition.
See the Instructions for Using 2016 Oregon Laws for details on how to determine the current state of the law. Each ORS chapter below that is affected by an Act of the 2016 regular session contains a notice (directly below the ORS chapter number) describing how the ORS chapter is affected. To see how an entire ORS volume is affected by the 2016 regular session, see the 2016 Update to 2015 Oregon Revised Statutes.
