ORS 34.670 Replication following return; hearing

The plaintiff in the proceeding, on the return of the writ, may, by replication, signed as in an action, controvert any of the material facts set forth in the return, or the plaintiff may allege therein any fact to show, either that imprisonment or restraint of the plaintiff is unlawful, or that the plaintiff is entitled to discharge. Thereupon the court or judge shall proceed in a summary way to hear such evidence as may be produced in support of or against the imprisonment or restraint, and to dispose of the party as the law and justice of the case may require.
