Indiana Code Title 36. Local Government § 36-7-4-1212

Sec. 1212.  ADVISORY.  Because long range planning studies of population, land use, schools, recreation, and public ways involve substantial expenditures, a township that joins with a municipality or county may not withdraw from the joinder, unless:

If the petition is received, the township executive shall certify the petition to the county election board under IC 3-10-9-3.  The board shall place the question on a ballot to be submitted at the next general election for the township in the form prescribed by IC 3-10-9-4.  If the township repays the amount expended for planning and zoning purposes that exceeds the amount contributed by the township and a majority of the voters voting in the election vote in the affirmative, the township may withdraw from its joinder with the municipality or county.
