2011 ORS § 25.200¹
Arrest of obligor for failure to appear

(1) If the obligor fails to appear for examination or further examination, the Attorney General or a district attorney may apply to the court which issued the order to appear for an order directing the issuance of a warrant for the arrest of the obligor. The motion shall be accompanied by an affidavit which shall state the relevant facts and whether the obligor contacted the Department of Justice or district attorney, as appropriate. If the court finds that the obligor had notice and failed to appear, the court shall order the issuance of a warrant for the arrest of the obligor in order to bring the obligor before the court to show cause why the obligor should not be held in contempt for a failure to appear as ordered.

(2) If the matter has been certified to the court for a contempt hearing and the obligor, having been properly served, fails to appear, the court shall order the issuance of a warrant for the arrest of the obligor. Upon arrest, the obligor shall be brought before the court to show cause why the obligor should not be held in contempt for a failure to appear as ordered. [Formerly 23.845 [bad link]; 1989 c.599 §4]
