Ind. Code § 36-7-4-610.5
This section applies to a proposal, as described in section 602(c) of this chapter, to change the zone maps incorporated by reference into the zoning ordinance. If, not later than one hundred eighty (180) days after adoption of the proposal, the legislative body finds that the proposal was adopted as a result of a person's intentional misrepresentation or omission of material facts, the legislative body may, by a three-fourths (3/4) vote (as described in IC 36-1-8-14), adopt an ordinance to nullify any change in the zone maps that resulted from the misrepresentation or omission. Such an ordinance may be adopted by the legislative body without being referred to the plan commission for consideration and recommendation under sections 604, 605, and 608 of this chapter.
