At least sixty days, but not more than two years, after submission of the proposed charter to the affected governing bodies, the proposed charter must be submitted to a vote of the qualified electors of each affected county and city at a primary or general election held concurrently. The question on the ballot at the election must be framed in a manner that fairly and accurately describes the substance of the proposed charter. If the proposed charter has been submitted to a vote of the qualified electors of a county or city, the governing body may call a special election to resubmit the proposed charter to a vote of the qualified electors, and the special election must take place at least sixty days after the call for the special election.
