Oregon Revised Statutes Public Financial Administration § 293.485

When any instrument is paid, other than as authorized by ORS 293.465 to 293.480, such wrongful payment shall not relieve the political body issuing the instrument from liability to the true and lawful owner thereof; but the officer or person making such wrongful payment and the sureties on the official bond of the officer or person, if any, shall be responsible to the political body represented by the officer or person in making such payment, for the full amount of the loss occasioned thereby.
