Section 1602 - Number of trustees; determination of change1. At the first annual meeting next after the erection of a common school district the electors shall determine, by resolution, whether the district shall have one or three trustees; and if they resolve to have three trustees, shall elect the three for one, two and three years, respectively, and shall designate by their votes for which term each is elected; thereafter in such district, one trustee shall be elected for three years at each annual meeting to fill the office of the outgoing trustee; and if they resolve to have one trustee, shall elect the trustee for a one-year term; thereafter in such district a trustee shall be elected for one year at each annual meeting to fill the office of the outgoing trustee.2. The electors of any common school district having three trustees shall have power to decide at any annual meeting by a majority vote of those present and voting, whether the district shall have a sole trustee or three trustees. If they resolve to have a sole trustee, the trustees in office shall continue in office until their terms of office shall expire. No election of a trustee shall be had in the district until the offices of such trustees shall become vacant by the expiration of their terms of office or otherwise, and thereafter but one trustee shall be elected for said district.3. The electors of a common school district having but one trustee may determine at an annual meeting, by a two-thirds vote of the legal voters present and voting thereat, to have three trustees; and upon the adoption of a resolution to that effect, shall proceed to elect three trustees or such number as may be necessary to form a board of three trustees, in the same manner as provided in this section for the election of three trustees at the first annual meeting after the erection of a district; and thereafter in such district, one trustee shall be elected for three years, at each annual meeting, to fill the office of the outgoing trustee.
