A circuit court denied the motion, ruling the search was lawful because the bag was within Coffee's reach. An appellate court also concluded the search was lawful, but said the facts of the case were irrelevant because as a matter of law, police may always search the passenger compartment of a vehicle upon an OWI arrest.
