The respondent against whom a verified complaint, as the same may have been amended, is filed and on whom a notice of hearing has been served, may file a written verified answer in person or through an attorney within ten (10) days from the service of the notice of hearing. The answer shall contain a general or specific denial of each and every allegation of the complaint controverted by the respondent or a denial of any knowledge or information thereof sufficient to form a belief and a statement of any matter constituting a defense. Any allegation in the complaint which is not denied or admitted in the answer in the above manner, shall be deemed admitted. The answer or any part thereof may be amended as a matter of right at any time prior to ten (10) days before a public hearing and thereafter in the discretion of the presiding member on application duly made therefore. The commission may proceed, notwithstanding any failure of the respondent to file an answer within the time provided herein, to hold a hearing at the time and place specified in the notice of hearing and may make its findings of fact and enter its report and order upon the testimony taken at the hearing.
