(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; 1989 c.599 §4]
