Unless prohibited by the national organic program, the department, the attorney general, an individual, a private organization or association, a county, or a city may bring an action in district court to restrain a producer, handler, or retailer from selling an agricultural product by false or misleading advertising claiming that the agricultural product is organic. A petitioner shall not be required to allege facts necessary to show, or tending to show, a lack of adequate remedy at law, or that irreparable damage or loss will result if the action is brought at law or that unique or special circumstances exist.
