Section 60 ILCS 1/80-5 - Township board membership; officers(a) In each township, the township board shall consist of the supervisor and 4 other members elected at large from the township under Section 50-5. The township clerk shall be the clerk of the township board but not a voting member, except that in the case of a tie vote to fill a vacancy in a township office, the clerk shall be entitled to cast one vote. Each person on the township board shall cast but one vote. The supervisor shall be the chairman of the board.(b) In towns organized under Article 15, all the powers vested by law in the township board shall be exercised by the city council.(c) The designations "town auditors", "board of trustees", "board of town trustees", "board of township trustees", and "town board" are changed to "township board". Wherever the terms "auditors", "board of trustees", "board of town trustees", board of township trustees", or "town board" are used in this or any other Act to refer to township officers provided for by this Section, they mean the township board. Wherever the term "trustees" is used in this or any other Act to refer to township officers provided for by this Section, it means the members of the township board other than the township supervisor.(d) The change made by Public Act 79-341 does not reduce the term of any member of a town board of auditors elected before its effective date (October 1, 1975) nor does it invalidate any action taken by a board of town auditors or town trustees by reason of the designation used for the board in relation to the action taken.
