No party to an arbitration including, but not limited to, a property owner, a property owner's agent, an appraisal district, or an arbitrator, may seek the comptroller's advice or direction on a matter relating to a pending arbitration under Tax Code, Chapter 41A. An arbitration is pending from the date a request for arbitration is filed and continues until delivery of the arbitrator's final arbitration determination and award pursuant to Tax Code, §41A.09. The prohibition in this subsection shall not apply to administrative matters assigned to the comptroller, such as the processing of arbitration requests and deposits.
