All exemptions and privileges recognized under Texas law are recognized in agency hearings to the same extent as they are recognized in civil cases in the courts of this state. If a party or witness is asked to reveal privileged material or conversations, the party may make a motion with the administrative law judge for such protective orders as are reasonable and necessary or may refuse to provide the information and assert the privilege in response to a motion to compel. The administrative law judge shall hold such hearings and issue such orders on motions to compel or requests for protective orders as are required by the law applicable to the facts and circumstances of the case.
