A. Unless otherwise provided by law, the validity or applicability of a rule may be determined in an action for declaratory judgment in the district court of Santa Fe county, if the rule, or its threatened application, interferes with or impairs, or threatens to interfere with or impair, the interests, rights or privileges of the plaintiff. Any representative association, including but not limited to trade associations, labor unions or professional organizations, may file the action if one or more of its members could qualify as a plaintiff. The agency shall be made a party to the action. A declaratory judgment may be rendered whether or not the plaintiff has requested the agency to pass upon the validity or applicability of the rule in question.

B. The district court of Santa Fe county may enter orders after reasonable notice and hearing upon any matter not otherwise provided for in the Administrative Procedures Act, including but not limited to procedural or substantive matters of law or equity. This right may be utilized at any stage of a proceeding, and failure to utilize the right until final decision, action or order shall not be deemed a waiver thereof. If such questions are raised upon review or appeal in the court of appeals, the court of appeals may enter any orders which could have been entered by the district court.
