Michigan Compiled Laws, Chapter 290. Weights, Measures and Standards § 290.429a

Sec. 9a.Except as otherwise provided in this act, a referendum under this act shall be valid for 5 years. Every 5 years, the department shall conduct a referendum at which growers shall vote whether or not the commission shall continue to levy the assessments and otherwise carry out this act. If a majority of the growers voting who represent a majority of the hundredweight sold in the previous year vote against having the commission continue to function, the commission shall cease its operations and deliver its assets to the director who shall transfer the assets to Michigan state university for potato research. A grower is entitled to 1 vote and the grower must be able to verify the hundredweight claimed as being sold on the ballot.
