Oregon Revised Statutes Occupations and Professions § 676.220

(1) If at any time the board suspending or revoking the license of any licentiate of a health care profession determines that such licentiate is continuing to practice the health care profession notwithstanding, the board shall in its own name bring an action to enjoin such licentiate.

(2) If the court shall find that the licentiate has been or is continuing the practice of the health care profession for which the license has been revoked or suspended it shall issue an injunction restraining the licentiate. The commission of a single act constituting the practice of the respective health care profession shall be prima facie evidence warranting the issuance of such injunction.
