(1) The Commissioner of the Bureau of Labor and Industries shall enforce ORS 652.310 to 652.414 and to that end may:
(a) Investigate and attempt equitably to adjust controversies between employers and employees in respect of wage claims or alleged wage claims.
(b) Take assignments, in trust, of wage claims or judgments thereon, liens and other instruments of security for payment of wages from the assigning employees, spouses, parents or legal guardians, having a right to the wages of such employees. All such assignments shall run to the commissioner and any successors in office. The commissioner may sue employers on wage claims and other persons or property liable for any payment thereof thus assigned with the benefits and subject to existing laws applying to actions by employees for collection of wages. The commissioner is entitled to recover, in addition to costs, such sum as the court or judge may adjudge reasonable as attorney fees at trial and on appeal. The commissioner may join in a single proceeding and in one cause of action any number of wage claims against the same employer. If the commissioner does not prevail in such action, the commissioner shall pay all costs and disbursements from the Bureau of Labor and Industries Account.
(c) Make complaint in a criminal court for any violation of any law providing for payment of wages and imposing a penalty for its violation as for a crime.
(d) In any case where a civil action may be brought under this chapter for the collection of a wage claim, provide for an administrative proceeding to determine the validity and enforce collection of the claim. The administrative proceeding shall be conducted as provided in this chapter, and is subject to the employer’s right to elect a trial in a court of law.
(2) An assigning wage claimant shall not be regarded as a party to any court action brought by the commissioner under this section for any purpose.
