Iowa Code § 322A.3: New franchise.

In the event that a franchiser is permitted to terminate or not continue a franchise, and is further permitted not to enter into a franchise for the line-make in the community, no franchise shall thereafter be entered into for the sale of motor vehicles of that line-make in the community, unless the franchiser has first established, in a hearing held under the provisions of this chapter, that there has been a change of circumstances so that the community at that time can be reasonably expected to support the dealership.
