If the respondent files a notice of defense admitting all parts of the accusation, or fails to file a notice of defense or fails to appear at the hearing, the Superintendent may take action based on the respondent’s express admissions or upon other evidence, including official reports, except that where the burden of proof is on the respondent to establish that the respondent is entitled to the action sought, the Superintendent may act without taking evidence. Nothing herein shall be construed to deprive the respondent of the right to make any showing by way of mitigation. (Amended by Ord. No. 139,419, Eff. 11/30/69.)
