(a) An administrative review is an informal review that determines whether a decision or action was appropriate under applicable laws and rules. An administrative review is not a formal hearing and does not involve formal examination and cross-examination of witnesses.(b) If you do not waive your right to request an administrative review, we may not finalize any decision or action that is the subject of the review until you exhaust your due process rights concerning the decision or action. However, you may not be able to operate pending due process for some enforcement actions as provided by Division 3 of this subchapter (relating to Operating Pending and Administrative Review and Due Process Hearing).
