The Supreme Court ruled that although the Fourth Amendment to the United States Constitution may tolerate unrelated investigations that do not prolong the detention, the authority for the seizure or stop ends when the task tied to the traffic violation are, or should have been completed. The Court stated that the officer, in making the stop, must be diligent in not prolonging the stop for unrelated investigations.
In this case, the police had finished issuing all tickets and the occupants objected to a dog sniffing the vehicle for drugs. Following some period of time after traffic matter was concluded, the dog sniffed the vehicle and alerted the officers to the presence of narcotics. The detention past the time the traffic matter investigation's conclusion was an unlawful seizure according to the Court.
This is a significant decision as it reasserts the right to be free from unreasonable seizures.
