Oregon Revised Statutes Mortgages and Liens § 87.212

A person claiming a lien under ORS 87.152 to 87.162 for the storage of fungible chattels shall not sell more of those chattels than is necessary to pay charges due that person for the storage. If a person unnecessarily sells fungible chattels without the consent of the owner thereof, the person shall, for each offense, forfeit to the owner of the chattels a sum equal to the fair market value of the chattels unnecessarily sold and 50 percent of the fair market value in addition as a penalty. The owner shall recover such value and penalty by an action at law.
