In Green v. City and County of San Francisco, published May 12, 2014, the 9th Circuit Court of Appeals reversed summary judgment granted to the defendant police officers and agency arising out of an incident in which a woman was mistakenly pulled over and held at gunpoint by officers on suspicion of driving a stolen vehicle. An officer's automatic license plate reader misread a digit on the plaintiff's car, and the plate came back as one belonging to a stolen vehicle that was a different make, model, color, and type of vehicle than the plaintiff's. The officer could not read the actual license plate. Because the officer was busy, he radioed dispatch with the mistaken number and the make and model of the plaintiff's car. Another officer knew about the license plate radioed in, that it belonged to a grey truck, and that the first officer had read it on a dark Lexus car. The second officer saw the plaintiff's car, read the first three digits on the plate, matched them to the report, followed the car until backup arrived, and then executed a "high risk" stop of the car. This involved four to six officers ordering plaintiff out of her car at gunpoint, handcuffing her, and searching her. The district court found that the officers make a reasonable mistake, and had used force appropriate for an investigatory stop; and that because the officers had not violated the plaintiff's rights, the agency was entitled to summary judgment as well.
The Ninth Circuit ruled that material issues of fact defeated summary judgment. Whether the initial officer was reasonable in reporting the license plate hit without visually confirming the license plate number, and whether the second officer was reasonable in relying on the message without visually confirming the entire license plate number (or matching the vehicle to the stolen-vehicle report) were issues of fact that defeated summary judgment on violation of the plaintiff's Fourth Amendment and California law rights. There were also triable issues of fact on whether plaintiff's detention was a de facto arrest (requiring probable cause rather than merely reasonable suspicion) and whether the officers used excessive force (because handcuffing and holding a person at gunpoint are generally excessive for stops based only on reasonable suspicion, absent circumstances indicating danger to the officers or others). Viewing the facts in the light most favorable to the plaintiff, there were issues of fact that defeated summary judgment based on qualified immunity. The issues of fact on the officers' liability defeated summary judgment for the agency.
