Each division may have an executive director appointed by the mayor with the approval of a vote of five members of the council, who shall be an officer of the city and shall be responsible for the supervision and control of such officer's jurisdiction. Said executive director shall not be subject to the city merit system and shall serve at the pleasure of the mayor; provided, however, each such officer shall be removed from office only upon recommendation of the mayor and approval of five council members. Upon the first vacancy, of any nature whatsoever, in the office of police chief or fire chief, the mayor may appoint the police chief and fire chief, respectively, from outside the said merit system, with the approval of five members of the council who shall serve at the pleasure of the mayor; provided, however, such officers shall be removed from office only upon recommendation of the mayor with the approval of five council members.

In addition to the city attorney, the mayor, from time to time in his sole discretion, is authorized to obtain additional legal counsel outside of the city merit system to advise and defend him in his capacity of mayor and in the pursuit of the operation of government.
(c) Upon approval by a majority of those present and voting, the council, from time to time when it deems necessary and reasonable, is authorized to obtain legal counsel outside the city merit system to advise and defend them in their respective capacities as council members and in the pursuit of the operation of government.
