Whether a sniff by a drug-detection dog conducted in the common area of an apartment building is a Fourth Amendment search under Florida v. Jardines

QUESTIONS PRESENTED Police entered an apartment building through an unlocked outer door and led a trained narcotics detection dog to a third-floor hallway, where the dog alerted to the presence of narcotics outside of respondent’s unit. Police obtained a search warrant based on the dog’s alert and, upon executing the warrant, seized cannabis from respondent’s apartment. The questions presented are: 1. Whether a sniff by a drug-detection dog conducted in the common area of an apartment building is a Fourth Amendment search under Florida v. Jardines, 569 U.S. 1 (20138). 2. If the dog sniff was an unreasonable search, whether the good-faith exception to the exclusionary rule applies.
