Oregon Revised Statutes Procedure in Criminal Matters Generally § 135.763

(1) The district attorney, after receiving a notice requesting trial under ORS 135.760, shall, within 90 days of receipt of the notice, bring the inmate to trial upon the pending charge.

(2) The court shall grant any reasonable continuance with the consent of the defendant.

The fact of imprisonment is not good cause for the purposes of this subsection.
