American Traffic Solutions, Inc. v. The City of Knoxville, Tennessee, et al.

This appeal concerns the application of a statutory amendment to a contract the plaintiff had with the city. The plaintiff claims the amendment to Tennessee Code Annotated section 55- 8-198, effective July 1, 2011, violates article I, section 20 of the Tennessee Constitution. In the alternative, the plaintiff argues that the amendment does not apply to existing contracts. The trial court concluded that the retroactive application of the amendment was not a constitutional violation. The plaintiff appeals. We affirm.
