Supreme Court of Iowa May 7, 2003, 02-0415 (James Enterprises, Inc. v. City of Ames)

CARTER, Justice.

Plaintiffs and intervenor, who are the owners of food service establishments in the City of Ames, appeal from an adverse judgment in a claim seeking declaratory and injunctive relief that would preclude enforcement of a local ordinance banning smoking. It is the contention of the food service establishments that the ordinance in question contravenes controlling state law.
