Within 90 days after final approval by the temporary corn marketing program committee of any proposed corn marketing program, the Director shall determine by referendum whether the affected producers assent to such proposed corn marketing program. The proposed corn marketing program is approved when a majority of those voting in the referendum vote in favor of such proposed corn marketing program. Following such approval the Department shall file the program with the Secretary of State as provided in Section 5-65 of the Illinois Administrative Procedure Act.
If any proposed corn marketing program is not approved by such referendum, no additional referendum on such corn marketing program may be held for 2 years from the date of the close of such referendum period. A succeeding referendum shall be called by the Director upon request by petition of 2,500 producers of corn with at least 10 signers of such petition from each of 50 counties. Prior to holding a succeeding referendum, the Director shall appoint a temporary corn marketing program committee who are corn producers and shall follow the procedures as set forth in Section 6.
