572 U.S. 393 (2014), U.S. Supreme Court
Navarette v. California sits at the intersection of public safety and Fourth Amendment privacy, addressing when police may stop a car based solely on an anonymous 911 report of dangerous driving.
Does the Fourth Amendment permit a traffic stop based solely on an anonymous 911 tip alleging dangerous driving, when officers corroborate only identifying details and observe no independent traffic violations before stopping the vehicle?
Under Terry v. Ohio and its progeny, an officer may conduct a brief investigatory stop when there is reasonable suspicion—specific, articulable facts, viewed under the totality of the circumstances—that criminal activity may be afoot. Anonymous tips can supply reasonable suspicion if they exhibit sufficient indicia of reliability, including a basis of knowledge (e.g., eyewitness account), contemporaneity, detailed identifying information, and features that enhance verifiability and accountability (e.g., 911 systems that can record, locate, and trace callers, and legal penalties for false reporting). Officers need not personally observe criminal behavior if the reliable tip provides reasonable suspicion of an ongoing or imminent offense.
Yes. The anonymous 911 tip exhibited sufficient indicia of reliability to create reasonable suspicion that the driver was engaged in drunk or reckless driving, thereby justifying the traffic stop under the Fourth Amendment.
Navarette refines the jurisprudence on anonymous tips and reasonable suspicion by identifying circumstances in which a 911 report can justify a vehicle stop without independent observation of illegality. It underscores that contemporaneous, eyewitness 911 tips about dangerous, ongoing conduct—especially drunk or reckless driving—may suffice under Terry's totality test. For students, the case is a key comparative with Alabama v. White (anonymous tip plus predictive corroboration is sufficient) and Florida v. J.L. (bare anonymous tip is insufficient), illustrating how reliability can be established through different combinations of factors, including the emergency context and 911 system features. It also highlights the balance courts strike between preventing imminent harms and guarding against overreliance on anonymous accusations.
