Sec. 2.01. BOARD OF TRUSTEES. (a) The fund is governed by a board of trustees consisting of the following nine members:

(1) the mayor of a municipality to which this Act applies or a qualified mayoral designee;

(2) two members of the governing body of a municipality to which this Act applies, appointed by that governing body;

(3) two active members who are fire fighters below the rank of fire chief, elected by secret ballot by a majority of the votes cast by the members of the fire department;

(4) two active members who are police officers below the rank of police chief, elected by secret ballot by a majority of the votes cast by the members of the police department;

(5) a retiree representative of the fire department, elected by secret ballot by a majority of the votes cast by the retirees of the fire department and the surviving spouses who are receiving benefits with respect to deceased members or retirees of the fire department; and

(6) a retiree representative of the police department, elected by secret ballot by a majority of the votes cast by the retirees of the police department and the surviving spouses who are receiving benefits with respect to deceased members or retirees of the police department.

(b) The board, through its secretary, shall administer the required elections of the active member and retiree representatives by mailing ballots to all eligible members, retirees, or beneficiaries. Only retirees and surviving spouses who are currently receiving benefits from the fund are eligible to vote for the retiree representatives. If no candidate receives a majority of the votes cast for any trustee position, the board shall hold a run-off election in which the only candidates are the candidates who received the highest and second-highest number of votes cast. If a candidate for trustee is unopposed in an election, the board shall certify the candidate as elected to the board on the executive director's certification that the candidate is eligible and is unopposed for election.
