This certification request from the District IV Court of Appeals in Waukesha, involves questions about the constitutionality of a dog sniff of the exterior of a vehicle at the tail end of a traffic stop. The stop, which started with a police officer’s suspicion of traffic violations, ultimately resulted in the discovery of cocaine and a switchblade stashed in the cushions of the front seat.
The Supreme Court has been asked to determine if a dog sniff of a stopped vehicle constitutes a "search" under the Wisconsin Constitution, and if the dog sniff impermissibly extended the amount of time required for a traffic stop. From Clark County.
