ORS 471.655: Owner may defend; evidence concerning nuisance.

(1) The owner of any property closed or restrained, or to be closed or restrained, may appear at any time between the filing of the complaint and the trial and show cause why the court should cancel or refrain from issuing any judgment orders as against the owner. In order to obtain such relief, the owner must prove to the satisfaction of the court that the owner is the lawful owner of the property and, further, that with reasonable care and diligence the owner could not have known of the illegal use of the owner’s property.

      (2) Evidence of the general reputation of the premises upon which a nuisance is alleged to exist is admissible in evidence for the purpose of proving the existence of the nuisance, and of knowledge of, and of acquiescence and participation therein, on the part of persons charged with maintaining or assisting in the maintenance of a nuisance.
