Utah Code § 7-1-309
The commissioner may conduct or cause to be conducted hearings relating to matters within his supervisory jurisdiction and shall establish rules for discovery and other procedures applicable to the hearings consistent with the provisions of the Utah Rules of Civil Procedure. The decision whether or not to hold a formal hearing on any matter coming before the commissioner under this title shall be solely within the discretion of the commissioner. His failure or refusal to hold a formal hearing is not a ground for reversal of any decision or order of the commissioner unless the reviewing court finds that such failure or refusal has deprived an interested party of due process of law, or that a formal hearing is required by the provisions of this title.
