(a) Any applicant for promotion to any position in a paid police department may personally review such applicant's examination questions, answers and scores to all parts of any competitive examination within five days after the posting of results of the competitive examination. Such five days shall not include the day the examination results are posted, nor any day that the office of the recorder of the city is not open for business to the public. The commission shall not certify the list of eligibles until all procedures before the commission under this section have been exhausted. The commission shall provide any applicant requesting review of such applicant's examination questions, answers and scores with a location to review such materials.

(b) If any applicant feels aggrieved by the answers and/or scores received on a promotional competitive examination, the commission shall, at the request of such applicant made within five days as calculated above, appoint a date, time and place for a public hearing, at which time such applicant may appear, with or without counsel. The commission shall review all parts of the competitive examination questions, answers and scores of the aggrieved applicant, and testimony shall be taken.

The commission shall subpoena, at the expense of the applicant, any competent witnesses requested by such applicant.

(c) After such review, the commission shall render a decision either in favor of the applicant, and therefore adjust the certified eligibility list to provide for such applicant's adjusted score, or the commission shall rule that the applicant's prior score should remain unchanged. Any decision rendered by the commission under this section shall be in writing and shall set forth findings of fact and conclusions of law relied upon to reach such decision.

(d) The commission shall not certify a list of eligibles after the completion of a competitive promotional examination until all applicants for such position have exhausted the procedures before the commission set forth in this section.

(e) If any applicant is aggrieved by a decision rendered by the commission under this section, such applicant may, within twenty days of the date of the commission's decision, seek judicial review thereof in the circuit court of the county wherein such municipality is located. Nothing in this section shall be construed as depriving such applicant of the right to seek a writ of mandamus to the appropriate court within the time specified in this subsection.
