(D) Within sixty business days after receipt of the complaint, or, if an informal meeting is held, within sixty days of such meeting, the investigator shall file a written report of the results of the investigator's investigation with the superintendent. Within fourteen business days thereafter, the superintendent shall review the report and determine whether there exists reasonable and substantial evidence of a violation of section 4735.18 of the Revised Code by the licensee. If the superintendent finds such evidence exists, within seven business days of the determination, the superintendent shall notify the complainant and licensee of the date of a hearing to be held by a hearing examiner pursuant to Chapter 119. of the Revised Code within fifteen days but not prior to seven days thereafter, except that either the superintendent or the licensee may request an extension of up to thirty business days for good cause shown. If the superintendent finds that such evidence does not exist, within five business days thereafter, the superintendent shall so notify the complainant and licensee of the superintendent's determination and the basis for the determination. Within fifteen business days after the superintendent notifies the complainant and licensee that such evidence does not exist, the complainant may file with the division a request that the commissioners review the determination. If the complainant files such request, the commissioners shall review the determination at the next regularly scheduled meeting held at least fifteen business days after the request is filed. The commission shall hear the testimony of either the complainant or the licensee at the meeting upon the request of the complainant or licensee. If the commissioners affirm the determination of the superintendent, the superintendent shall so notify the complainant and the licensee within five business days thereafter. If the commissioners reverse the determination of the superintendent, a hearing shall be held and the complainant and licensee notified as provided in this division. After the date of a hearing to be held by a hearing examiner has been scheduled pursuant to division (D) of this section, but before the issuance of the report of findings of fact and conclusions of law pursuant to division (E) of this section, the superintendent upon receipt of additional evidence, may withdraw the notice of hearing. Withdrawal by the superintendent does not constitute evidence that the original notice of hearing was not substantially justified. Upon withdrawal of the notice of hearing, the superintendent shall notify the complainant and licensee of the superintendent's determination and basis for the determination. Within fifteen business days after the superintendent notifies the complainant and licensee, the complainant may file with the superintendent a request that the Ohio real estate commission review the determination. The commission shall review the request as provided in division (D) of this section.
