Indiana Code Title 8. Utilities and Transportation § 8-23-17-34

Sec. 34. This chapter is not applicable to the purchase of a parcel of real property by an agency if the agency head gives notice in writing to the owner of the property not later than the date of its first offer to purchase the property that the agency will not exercise a right it may have to acquire the property through exercise of the power of eminent domain. Proceedings in eminent domain may not thereafter be instituted by the agency with respect to the real property unless the notice is expressly revoked in writing. If the notice is revoked, the provisions of this chapter are applicable as if the agency had not given notice under this section.
