The county commissioners may call a referendum on approval of a property tax levy. The referendum may be held at the same time as any other referendum or election, but may not be otherwise held within the period of time beginning 30 days before and ending 10 days after any other referendum or election to be held in the county and already validly called or scheduled by law at the time the tax referendum is called. The referendum shall be conducted by the county board of elections. The clerk to the board of commissioners shall publish a notice of the referendum at least twice. The first publication shall be not less than 14 days and the second publication not less than seven days before the last day on which voters may register for the referendum. The notice shall state the date of the referendum, the purpose for which it is being held, and a statement as to the last day for registration for the referendum under the election laws then in effect.
The proposition submitted to the voters shall be substantially in one of the following forms:
If a majority of those participating in the referendum approve the proposition, the board of commissioners may proceed to levy annually a property tax within the limitations (if any) described in the proposition.
The board of elections shall canvass the referendum and certify the results to the board of commissioners. The board of commissioners shall then certify and declare the result of the referendum and shall publish a statement of the result once, with the following statement appended: "Any action or proceeding challenging the regularity or validity of this tax referendum must be begun within 30 days after (date of publication)." The statement of results shall be filed in the clerk's office and inserted in the minutes of the board.
Any action or proceeding in any court challenging the regularity or validity of a tax referendum must be begun within 30 days after the publication of the results of the referendum. After the expiration of this period of limitation, no right of action or defense based upon the invalidity of or any irregularity in the referendum shall be asserted, nor shall the validity of the referendum be open to question in any court upon any ground whatever, except in an action or proceeding begun within the period of limitation prescribed herein.
Except for supplemental school taxes and except for tax referendums on functions not included in subsection (c) of this section, any referendum held before July 1, 1973, on the levy of property taxes is not valid for the purposes of this subsection. Counties in which such referendums have been held may support programs formerly supported by voted property taxes within the general rate limitation set out in subsection (c) at any appropriate level and are not subject to the former voted rate limitation.
The proposition submitted to the voters shall be substantially in the following form: "Shall the property tax rate limitation applicable to ____ County be increased from ____ on the one hundred dollars ($100.00) value of property subject to taxation to ____ on the one hundred dollars ($100.00) value of property subject to taxation?"
If a majority of those participating in the referendum approve the proposition, the rate limitation imposed in subsection (c) shall be increased for the county.
