When such a city council has decided to establish and maintain, or to purchase and maintain, a public hospital under this Division 23, the mayor, with the approval of the city council, shall appoint a board of 3 directors for the hospital.
One of the directors shall hold office for one year, one for 2 years, and one for 3 years, from the first day of July following their appointments. At their first regular meeting the directors shall cast lots for the respective terms. Before the first day of July each year thereafter, the mayor, with the approval of the city council, shall appoint one director to take the place of the retiring director, who shall hold office for 3 years, and until his successor is appointed.
The city council may, by resolution, increase the membership of the board to 5 directors. Such resolution shall not affect the terms of the incumbent directors. Before the first day of July following the adoption of such resolution the mayor with the approval of the city council, shall appoint 3 directors, one to succeed the incumbent whose term expires and the 2 additional provided for in the resolution, for terms of 3, 4 and 5 years from July 1 of the year of the appointment. Thereafter, upon the expiration of the term of any director his successor shall be appointed for a term of 5 years and until his successor is appointed for a like term.
If the city council has, by previous resolution, increased the membership of the board to 5 directors, the city council may by new resolution increase the membership of the board by 2 new members in any one year up to a maximum of 11 directors. Such new resolution shall not affect the terms of incumbent directors. Before the first day of July following the adoption of the new resolution the mayor with the approval of the city council shall appoint a sufficient number of directors so that there will be a successor for the full term of each incumbent whose term expires, and the 2 additional provided for in the resolution for terms of 4 and 5 years from July 1 of the year of appointment. Thereafter, upon the expiration of the term of any director, his successor shall be appointed for a term of 5 years and until his successor is appointed and qualified for a like term.
The mayor, with the consent of the city council, may remove any director for misconduct or neglect of duty. Vacancies in the board of directors, however occasioned, shall be filled for the unexpired term in like manner as original appointments. No director shall receive compensation for serving as a director. No director shall be interested, either directly or indirectly, in the purchase or sale of any supplies for the hospital.
