In every city there shall be elected, or appointed, for a term of four years, in a manner to be provided by law, one commissioner of revenue, whose duties and compensation shall be prescribed by law; but should he be elected by the people, he shall be ineligible for reelection to the office for the next succeeding term.

Sec. 120.  In every city there shall be elected by the qualified voters thereof one city treasurer, for a term of four years, but he shall not be eligible for more than two consecutive terms, nor act as deputy for his immediate successor; one city sergeant, for a term of four years, whose duties shall be prescribed by law; and, a mayor, for a term of four years, who shall be the chief executive officer of such city.  All city and town officers, whose election or appointment is not provided for by this Constitution, shall be elected by the electors of such cities and towns, or of some division thereof, or appointed by such authorities thereof as the General Assembly shall designate.

The mayor shall see that the duties of the various city officers, members of the police and fire departments, whether elected or appointed, in and for such city, are faithfully performed.  He shall have power to investigate their acts, have access to all books and documents in their offices, and may examine them and their subordinates on oath.  The evidence given by persons so examined shall not be used against them in any criminal proceedings.  He shall also have power to suspend such officers and the members of the police and fire departments, and to remove such officers, and also such members of said departments when authorized by the General Assembly, for misconduct in office or neglect of duty, to be specified in the order of suspension or removal; but no such removal shall be made without reasonable notice to the officer complained of, and an opportunity afforded him to be heard in person, or by counsel, and to present testimony in his defense.  From such order of suspension or removal, the city officer so suspended or removed shall have an appeal of right to the corporation court, or, if there be no such court, to the circuit court of such city, in which court the case shall be heard de novo by the judge thereof, whose decision shall be final.  He shall have all other powers and duties which may be conferred and imposed upon him by general laws.
