Mo. Rev. Stat. § 621.175
Hearings in cases filed pursuant to section 536.050, RSMo, shall not be deemed to be contested cases and the procedures established by chapter 536, RSMo, or any other procedural requirements applicable to contested cases shall not apply to such hearings unless required by the provisions of the law relating to the administrative hearing commission, other independent statute or by constitutional provision. Unless the administrative hearing commission rules that special circumstances so require, and sets forth in writing such special circumstances and the reasons why they so require, evidentiary submissions shall be limited to written exhibits, physical evidence, testimony of persons present at the hearing, and affidavits. Cross-examination of persons testifying may be permitted, but shall be limited to situations where there are genuinely disputed questions of material facts. The administrative hearing commission shall maintain a transcript of all testimony and proceedings in hearings, and copies thereof shall be made available to any interested person upon the payment of a fee which shall in no case exceed the reasonable cost of preparation and supply. Rules of discovery shall not apply to hearings held under this section, but the administrative hearing commission, at the request of a party, or on its own motion, may issue subpoenas duces tecum, but not subpoenas ad testificandum, subject to and consistent with the procedures set forth in section 536.077, RSMo. In cases heard under this section the administrative hearing commission may take judicial notice of judicially cognizable facts as well as generally recognized technical or internal administrative facts of which the administrative hearing commission has specialized knowledge. Parties shall be notified either before the hearing, or during the hearing, or by reference in preliminary reports, or otherwise, of the material so to be noticed and shall be afforded an opportunity to contest or to object to the noticing of such material.
