    (c) Notwithstanding the provisions of subsection (a), the offices of township treasurer and trustee of schools of any township located in a Class II county school unit shall be abolished as provided in this subsection if all of the following conditions are met:
        (1) During the same 30 day period, each school board
    
of each elementary and unit school district that is subject to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished gives written notice by certified mail, return receipt requested to the township treasurer and trustees of schools of that township of the date of a meeting of the school board, to be held not more than 90 nor less than 60 days after the date when the notice is given, at which meeting the school board is to consider and vote upon the question of whether there shall be submitted to the electors of the school district a proposition to abolish the offices of township treasurer and trustee of schools of that township. None of the notices given under this paragraph to the township treasurer and trustees of schools of a township shall be deemed sufficient or in compliance with the requirements of this paragraph unless all of those notices are given within the same 30 day period.
        (2) Each school board of each elementary and unit
    
school district that is subject to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished, by the affirmative vote of at least 5 members of the school board at a school board meeting of which notice is given as required by paragraph (1) of this subsection, adopts a resolution requiring the secretary of the school board to certify to the proper election authorities for submission to the electors of the school district at the next consolidated election in accordance with the general election law a proposition to abolish the offices of township treasurer and trustee of schools of that township. None of the resolutions adopted under this paragraph by any elementary or unit school districts that are subject to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished shall be deemed in compliance with the requirements of this paragraph or sufficient to authorize submission of the proposition to abolish those offices to a referendum of the electors in any such school district unless all of the school boards of all of the elementary and unit school districts that are subject to the jurisdiction and authority of the township treasurer and trustees of schools of that township adopt such a resolution in accordance with the provisions of this paragraph.
        (3) The school boards of all of the elementary and
    
unit school districts that are subject to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished submit a proposition to abolish the offices of township treasurer and trustee of schools of that township to the electors of their respective school districts at the same consolidated election in accordance with the general election law, the ballot in each such district to be in substantially the following form:
    ----------------------------------------------------------

    ----------------------------------------------------------
        (4) At the consolidated election at which the
    
proposition to abolish the offices of township treasurer and trustee of schools of a township is submitted to the electors of each elementary and unit school district that is subject to the jurisdiction and authority of the township treasurer and trustee of schools of that township, a majority of the electors voting on the proposition in each such elementary and unit school district votes in favor of the proposition as submitted to them.
    If in each elementary and unit school district that is subject to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished a majority of the electors in each such district voting at the consolidated election on the proposition to abolish the offices of township treasurer and trustee of schools of that township votes in favor of the proposition as submitted to them, the proposition shall be deemed to have passed; but if in any such elementary or unit school district a majority of the electors voting on that proposition in that district fails to vote in favor of the proposition as submitted to them, then notwithstanding the vote of the electors in any other such elementary or unit school district on that proposition the proposition shall not be deemed to have passed in any of those elementary or unit school districts, and the offices of township treasurer and trustee of schools of the township in which those offices were sought to be abolished shall not be abolished, unless in each of those elementary and unit school districts remaining subject to the jurisdiction and authority of the township treasurer and trustees of schools of that township proceedings are again initiated to abolish those offices and all of the proceedings and conditions prescribed in paragraphs (1) through (4) of this subsection are repeated and met in each of those elementary and unit school districts.
    Notwithstanding the foregoing provisions of this Section or any other provision of the School Code, the offices of township treasurer and trustee of schools of a township that has a population of less than 200,000 and that contains a unit school district and is located in a Class II county school unit shall also be abolished as provided in this subsection if all of the conditions set forth in paragraphs (1), (2), and (3) of this subsection are met and if the following additional condition is met:
        The electors in all of the school districts subject
    
to the jurisdiction and authority of the township treasurer and trustees of schools of the township in which those offices are sought to be abolished shall vote at the consolidated election on the proposition to abolish the offices of township treasurer and trustee of schools of that township. If a majority of the electors in all of the school districts combined voting on the proposition vote in favor of the proposition, then the proposition shall be deemed to have passed; but if a majority of the electors voting on the proposition in all of the school district fails to vote in favor of the proposition as submitted to them, then the proposition shall not be deemed to have passed and the offices of township treasurer and trustee of schools of the township in which those offices were sought to be abolished shall not be abolished, unless and until the proceedings detailed in paragraphs (1) through (3) of this subsection and the conditions set forth in this paragraph are met.
    If the proposition to abolish the offices of township treasurer and trustee of schools of a township is deemed to have passed at the consolidated election as provided in this subsection, those offices shall be deemed abolished by operation of law effective on January 1 of the calendar year immediately following the calendar year in which that consolidated election is held, provided that if after the election, the trustees of schools by resolution elect to abolish the offices of township treasurer and trustee of schools effective on July 1 immediately following the election, then the offices shall be abolished on July 1 immediately following the election. On the date that the offices of township treasurer and trustee of schools of a township are deemed abolished by operation of law, the school board of each elementary and unit school district and the school board of each high school district that is subject to the jurisdiction and authority of the township treasurer and trustees of schools of that township at the time those offices are abolished: (i) shall appoint its own school treasurer as provided in Section 8-1; and (ii) unless the term of the contract of a township treasurer expires on the date that the office of township treasurer is abolished, shall pay to the former township treasurer its proportionate share of any aggregate compensation that, were the office of township treasurer not abolished at that time, would have been payable to the former township treasurer after that date over the remainder of the term of the contract of the former township treasurer that began prior to but ends after that date. In addition, on the date that the offices of township treasurer and trustee of schools of a township are deemed abolished as provided in this subsection, the school board of each elementary school, high school and unit school district that until that date is subject to the jurisdiction and authority of the township treasurer and trustees of schools of that township shall be deemed by operation of law to have agreed and assumed to pay and, when determined, shall pay to the Illinois Municipal Retirement Fund a proportionate share of the unfunded liability existing in that Fund at the time these offices are abolished in that calendar year for all annuities or other benefits then or thereafter to become payable from that Fund with respect to all periods of service performed prior to that date as a participating employee in that Fund by persons serving during those periods of service as a trustee of schools, township treasurer or regular employee in the office of the township treasurer of that township. That unfunded liability shall be actuarially determined by the board of trustees of the Illinois Municipal Retirement Fund, and the board of trustees shall thereupon notify each school board required to pay a proportionate share of that unfunded liability of the aggregate amount of the unfunded liability so determined. The amount so paid to the Illinois Municipal Retirement Fund by each of those school districts shall be credited to the account of the township in that Fund. For each elementary school, high school and unit school district under the jurisdiction and authority of a township treasurer and trustees of schools of a township in which those offices are abolished as provided in this subsection, each such district's proportionate share of the aggregate compensation payable to the former township treasurer as provided in this paragraph and each such district's proportionate share of the aggregate amount of the unfunded liability payable to the Illinois Municipal Retirement Fund as provided in this paragraph shall be computed in accordance with the ratio that the number of pupils in average daily attendance in each such district for the school year last ending prior to the date on which the offices of township treasurer and trustee of schools of that township are abolished bears to the aggregate number of pupils in average daily attendance in all of those districts as so reported for that school year.
    Upon abolition of the offices of township treasurer and trustee of schools of a township as provided in this subsection: (i) the regional board of school trustees, in its corporate capacity, shall be deemed the successor in interest to the former trustees of schools of that township with respect to the common school lands and township loanable funds of the township; (ii) all right, title and interest existing or vested in the former trustees of schools of that township in the common school lands and township loanable funds of the township, and all records, moneys, securities and other assets, rights of property and causes of action pertaining to or constituting a part of those common school lands or township loanable funds, shall be transferred to and deemed vested by operation of law in the regional board of school trustees, which shall hold legal title to, manage and operate all common school lands and township loanable funds of the township, receive the rents, issues and profits therefrom, and have and exercise with respect thereto the same powers and duties as are provided by this Code to be exercised by regional boards of school trustees when acting as township land commissioners in counties having at least 220,000 but fewer than 2,000,000 inhabitants; (iii) the regional board of school trustees shall select to serve as its treasurer with respect to the common school lands and township loanable funds of the township a person from time to time also serving as the appointed school treasurer of any school district that was subject to the jurisdiction and authority of the township treasurer and trustees of schools of that township at the time those offices were abolished, and the person selected to also serve as treasurer of the regional board of school trustees shall have his compensation for services in that capacity fixed by the regional board of school trustees, to be paid from the township loanable funds, and shall make to the regional board of school trustees the reports required to be made by treasurers of township land commissioners, give bond as required by treasurers of township land commissioners, and perform the duties and exercise the powers of treasurers of township land commissioners; (iv) the regional board of school trustees shall designate in the manner provided by Section 8-7, insofar as applicable, a depositary for its treasurer, and the proceeds of all rents, issues and profits from the common school lands and township loanable funds of that township shall be deposited and held in the account maintained for those purposes with that depositary and shall be expended and distributed therefrom as provided in Section 15-24 and other applicable provisions of this Code; and (v) whenever there is vested in the trustees of schools of a township at the time that office is abolished under this subsection the legal title to any school buildings or school sites used or occupied for school purposes by any elementary school, high school or unit school district subject to the jurisdiction and authority of those trustees of school at the time that office is abolished, the legal title to those school buildings and school sites shall be deemed transferred by operation of law to and invested in the school board of that school district, in its corporate capacity under Section 10-22.35B of this Code, the same to be held, sold, exchanged leased or otherwise transferred in accordance with applicable provisions of this Code.
    Notwithstanding Section 2-3.25g of this Code, a waiver of a mandate established under this Section may not be requested.
