ORS § 133.733
The contents of any wire, electronic or oral communication intercepted under ORS 133.724, or evidence derived therefrom, shall not be received in evidence or otherwise disclosed in any trial, hearing or other proceeding in any court of this state unless each party, not less than 10 days before the trial, hearing or proceeding, has been furnished with a copy of the court order, and accompanying application, under which the interception was authorized or approved. This 10-day period may be waived by the judge if the judge finds that it was not possible to furnish the party with the above information 10 days before the trial, hearing or proceeding and that the party will not be prejudiced by the delay in receiving such information.
