(2) The Citizens' Utility Board shall not intentionally make any false material statement in any material submitted to a utility for inclusion with a billing. If the utility believes that the Citizens' Utility Board has intentionally made false material statements in an enclosure, it may file a complaint with the Public Utility Commission of Oregon within five days of receipt. The Public Utility Commission of Oregon must review the complaint within 10 days, and if the commission determines that the Citizens' Utility Board has intentionally made false material statements, the commission shall give the Citizens' Utility Board of Governors written notification that specifies any false material statements made and the reasons why the commission determines the statements to be false.
