CA9: Stop suppressed as based on a hunch and represented at suppression hearing as a mere conclusion

Defendant was seen leaving a stash house with a box, and he was followed from a distance where he went to a liquor store and then somewhere else. He was stopped but the stop was without probable cause. There was no showing that he had drugs when he left the stash house and his driving was not indicative of “counter-surveillance.” Officer’s alleged expertise that it was a stash house was a mere unsupported conclusion. United States v. Cervantes, 678 F.3d 798 (9th Cir. 2012):

The government asks us to place heavy reliance on Hankel’s conclusory statement that, based on Hankel’s training and experience, the white box in Cervantes’s possession came from a “suspected narcotics stash house.” But in the absence of any underlying facts as to why Hankel suspected the house was a “stash house,” this statement is entitled to little, if any, weight in the probable cause analysis.

“One of the themes which runs through the decisions on the Fourth Amendment probable cause requirement is that when the ultimate probable cause determination is made, whether by a magistrate when a warrant is sought or upon a motion to suppress evidence obtained without a warrant, mere conclusions will not suffice.” 2 Wayne Lafave, Search and Seizure: A Treatise on the Fourth Amendment § 3.5(e), at 297 (4th ed. 2004). See, e.g., Illinois v. Gates, 462 U.S. at 239 (noting that “wholly conclusory” statements of officers are insufficient to establish probable cause); United States v. Ventresca, 380 U.S. 102, 108-09 (1965) (noting that “purely conclusory” statements of officers, without detailing any of the underlying circumstances, will be insufficient to establish probable cause); Nathanson v. United States, 290 U.S. 41, 47 (1933) (noting that an officer’s “mere affirmance of suspicion or belief without disclosure of supporting facts or circumstances” is insufficient to establish probable cause).

In United States v. Thomas, we noted that a conclusory allegation by law-enforcement that a particular house was a suspected narcotics stash house, was entitled to little (if any) weight in determining whether officers had satisfied the lower reasonable suspicion standard required to stop a vehicle leaving the house. 211 F.3d 1186, 1189-90 (9th Cir. 2000). We explained that the conclusory allegation, without any foundational facts, was akin to an anonymous tip and, consequently, was entitled to little weight. Id. at 1190.

Here, as in Thomas, Hankel’s statements amount to nothing more than conclusory assertions. Hankel failed to provide any underlying facts as to why he, or any other officers, suspected the house was a “narcotics stash location.” While Hankel’s training and experience are factors to be considered, “it is incumbent upon the arresting or searching officer to explain the nature of his expertise or experience and how it bears upon the facts which prompted the officer to arrest or search.” 2 Wayne Lafave, Search and Seizure: A Treatise on the Fourth Amendment § 3.2(c), at 45 (4th ed. 2004) (internal quotation marks omitted). Conclusory statements and a general claim of expertise will not suffice. Id.; Thomas, 211 F.3d at 1189-92.
