THE PEOPLE DID NOT DEMONSTRATE PROBABLE CAUSE FOR THE TRAFFIC STOP; THE 911 CALL WAS NOT PUT IN EVIDENCE AND THE RELIABILITY OF THE CALLER AND THE BASIS FOR THE CALLER’S KNOWLEDGE WERE NOT DEMONSTRATED; THE FACT THAT THE RELEVANT EVIDENCE WAS PRESENTED AT TRIAL WAS IRRELEVANT (CT APP).

The Court of Appeals, reversing the Appellate Division, determined the People did not present sufficient evidence at the suppression hearing. Probable cause for the traffic stop was based on a 911 call. But no evidence was presented to demonstrate the reliability of the caller or the basis for the caller’s knowledge. The fact that the relevant evidence was presented at trial did not matter. The appeal focuses on the evidence presented at the suppression hearing:

… [T]he officer’s only justification for the stop was the dispatcher’s report that a 911 caller had asserted that one of the vehicle’s occupants possessed a “long gun.” Initially, defendant claims that the stop was invalid because possession of a “long gun” is lawful in New York. We reject that claim as meritless (see Penal Law 265.00 [22]). However, the People failed to introduce the 911 recording, failed to introduce any evidence indicating whether the 911 caller was an identified citizen informant or an anonymous tipster, and failed to offer any explanation of the basis of the caller’s knowledge. In sum, the People put forward no relevant information concerning the circumstances surrounding the call at the hearing. Contrary to the People’s suggestion that an appellate court can consider evidence subsequently admitted at trial to justify affirmance of an order denying suppression, “the propriety of the denial must be judged on the evidence before the suppression court” … . Therefore, on the record of the suppression hearing, “whether evaluated in light of the totality of the circumstances or under the Aguilar-Spinelli framework, the reliability of the tip was not established” … . People v Walls, 2021 NY Slip Op 04949, CtApp 9-2-21
