Groves (defendant), a police officer, saw a dog running loose in violation of the city’s dog leash ordinance. The dog was running towards Mrs. Enright’s (plaintiff) home. Groves came up to the home where he encountered Enright’s eleven year old son and asked him if it was his dog. The boy said yes and told him his mother was sitting in the car parked at the curb by the house. Groves told the boy to put the dog inside the house and Groves walked towards the car. Groves asked Enright for her driver’s license, which she refused to produce. Groves told her to show her license or go to jail. Groves thereafter arrested Enright and charged her with violation of the dog leash ordinance. There is no city ordinance that requires Enright to produce her license on demand. As a result of this incident Enright was later convicted of violation of the dog leash ordinance. Enright sued Groves and the city and won a judgment in her favor. Groves and the city appealed the judgment to the Colorado Court of Appeals.
