What it's about

The Supreme Court overturned Florida’s ruling, finding that Aldo’s training and testing records supported his reliability and that Wheetley had probable cause—a reasonable basis to believe a search would find drugs—because Harris did not undermine that evidence.

The dispute asked when a drug-detection dog’s alert gives an officer enough reason to search a vehicle without a warrant.

Question presented

Does a drug-detection dog's alert to the exterior of a vehicle provide an officer with probable cause to conduct a warrantless search of the interior of the vehicle?

What the Court decided

Holding

Because training and testing records supported Aldo’s reliability in detecting drugs and Harris failed to undermine that evidence, Wheetley had probable cause to search Harris’s truck. 71 So. 3d 756, reversed.

Result
Reversed

The Court's reasoning

The Court said Aldo’s training and testing records supported his reliability, and Harris did not undermine that evidence. On that basis, Officer Wheetley had enough reason to search the truck.
