(1) Oral reprimand;

(3) Reduction in rank;
(4) Suspension;
(5) Discharge;
(B) Discipline may be imposed only for cause.
(C) Except as hereinafter provided, no policeman shall be suspended for more than five days, removed, or discharged except for cause, upon written charges, and after an opportunity to be heard in his own defense. The Chief of Police may be removed or discharged by the Mayor and cause need not be shown for removal of the Chief of Police. In any case the Mayor shall file with the City Council the reasons for the removal or discharge, which removal or discharge shall not become effective unless confirmed by a majority vote of the City Council. The City Council shall conduct a fair and impartial hearing of the charges. The City Council shall determine the sufficiency of cause for any removal or discharge.
(D) Nothing in this section shall be construed to prevent the Chief of Police from suspending without pay a member of his department for a period of not more than five days, but he shall notify the City Council in writing of such suspension. Any policeman so suspended may appeal to the City Council for a review of the suspension within 24 hours after such suspension, and upon such appeal the City Council may sustain the action of the Chief, may reverse it with instructions that the policeman receive his pay for the period involved, or may impose any other and further disciplining, depending on the facts presented.
